SD Card is Damaged. Try Reformatting it.

Anyone else getting this with their S4? I bought my S4 two weeks ago and a Sandisk 64gb card to go with it and started seeing this error about twice a day. I returned it for a Samsung SD and didn't see the error for almost a week until today.
The card actually appears to be fine, all I have to do is remount it after seeing the message and all is good, it's just worrisome cause I store all my photos on there. I'm wondering if it could be the phone itself? I have one day left to exchange it, but it's rooted.

SD Errors are because the card is physically moving when its being written to. This cause bad sectors on the card. Try putting a piece of thin scotch tape and cut to shape of the face of the SD Card. See if it fits more snug....
Are you jogging with the S4 or something? Samsung SD's are class 10 which I think write faster. Maybe that is less likely to cause damage because its written so fast? Not sure....
Try the tape trick and see if it reduces the problem. Else its a physical problem with the slot.

i also have a class 10 64gb, some guy on the forum posted this problem too, he said that by formating the card with a PC and then formating it with the format utility in the phone settings has solved his problem. If not, might be a slot problem like slider mentionned

I had this problem too with my 32 gig class 10. When I put my shock absorbant case on it my problem went away

I had never had an issue with a Sandisk card until my S3 ate a 32GB. I then started readibg how the S3 ate non- Samsung cards. I have been using a Samsung card with no issues

hope you make regular sdcard backups and copy to pc
polish_pat is correct, reformat your card with sdformatter, use Full Erase On and Size Adjustment On
Of course backup first
you shouldn't have to reformat again in phone--
if the card is good this should solve your issue

I had tried 3 different San disk 64GBP class 10 cards and had this problem, the fourth one works so far...doing some searching I found lots of complaints from lots of different device forums about this card. Only fix I found was running chkdsk repair on the card in Windows but this only worked for a few people ( couldn't save my first three cards)
anyway, imo exchange the card or better yet buy a different brand

Posting here as doing a search revealed this is the closest to the problem that I'm having. I've had my AT&T Samsung Galaxy S4 for approximately 1 month now. I purchased a Sandisk 32GB SD Card for the phone. Two days ago I began experiencing issues where when unlocking the phone I would notice the card would unmount then remount (this was in the notification bar). Later that night, the card unmounted and there wasn't any way to get it recognized again. I posted in some other forums and someone said there were some good posts here.
I've contacted Sandisk regarding the card and they refused any involvement stating it's a problem with the phone, not the card. They determined this because once I was able to get the phone to recognize the card and plugged the phone into the PC, the card was able to be read. As long as it's readable, it's fine. After dealing with this I eventually found my MicroSD to SD reader and plugged it into my media reader in my printer. I had quite a few issues from time to time reading the card, however I can't 100% for sure say whether this is the card or the printer.
Anywho, I grabbed copies of what I needed. Formatted the card on the PC, then formatted it on the phone. I began to copy my entries however at one point instead of saying I had 29.* GB Available, it said something like 2.0 EV of 3.0 PE or something like that... these weren't the typical numbers I've seen nor the units of storage space. I apologize that I can't recall that information. I reformatted again and it worked. Left the card in the phone empty over night then tried to copy files later today. This worked.
Now, approximately 48 hours after the problems began, I noticed more issues. SD card stated that it had been damaged and that I should reformat it. While this message stayed in notifications, I confirmed I was still able to read files on the SD card. When googling that error hoping I'd find more resources, the card again unmounted.
One of the resources I found had me do a CHKDSK /F /X on the card. I did this and found no issues. I've replaced it back into the phone and it seems to be working for the moment.
1) Are there any confirmations if this is a bad card, or if perhaps any applications are causing the card to do this? I do have QuickPic and have enabled some of the hidden file features if that helps.
2) Do we know if there are any logs that can be pulled to help verify this?
3) Is it a specific card? (I've heard SanDisk 32gb, but also have heard non-Samsung SD will fail)
Looking to get this resolved ASAP. This card was purchased directly from AT&T when the phone was purchased. I am just looking for some confirmation that if I have to buy another card, I'm not going to gamble if that's going to have the problem as well.
Thanks! If I forgot anything please ask!
Edit: Per the thread, this is a Class 4 card. Also the phone was not moving when it was writing data. I've been couch-ridden all day and unlocked it. I don't believe the phone was in deep-sleep mode as I had received a text not long before I began noticing these messages.

same problem
i have the same problem and guess what ?
the phone is acting like the ***** it stays ok for 3 weeks while that time i download to many stuff to my ext card 32g Elixir Memory after that it crach and give me notification that sd card is damaged and i have to reformat it sucks
by the ****in way this's the fifth time it crash i changed the memory to sony and same and changed to Kodak and the same
so abso****inlotley its the S3 for me soon its going to trash

This works! It fixed the issue I was having with my SanDisk 64GB.

Blank SD Card SD card is blank or has unsupported files

I bought a generic 64GB sd card off ebay. Card worked in my phone till i tried to transfer files to it then all of a sudden after reboot it shows "Blank SD Card SD card is blank or has unsupported files" The funny thing is this card read in any other phone my wifes s3 my mothers LG and even my co workers S4 (granted shes on ATT) It does not matter how many times i take it out and put it back in I still get the blank SD. I put it in a card reader and all the files are there. I have formated it to ext4 fat32 and it came fatext and once in a while if i format it it shows up in phone again till i try to put files on it and back to blank sd. I can read and write files to it no problem in another phone and sd card reader. plug and unplug it all day and it still loads up. Except on my phone. Im thinking i have a defect on my new phone. Anyone else have this problem? I even updated to the MF9 to see if this was a bug maybe they fixed. But i think its the phone when i was rooted with TWRP even twrp would freeze if i had the card plugged in till i ejected it. Oh yea cant even format it in the phone it has the option but does not work either. Some times it just keeps telling me its safe to remove card no matter how many times I hit mount.

These are the sort of things generic cards do. Your best solution is to get an authentic sd card. Be it big name brand or small.

I had this issue on my first sgs4, it also had some issue where it wasn't reading the battery properly (always at 100%). The first 32 GB card did this,read it fine at first then the sd went and did the issue you're having. Returned the phone and the same thing happened on the new phone. The card was some off brand (pny I think). Picked up a 64GB SanDisk has been working so far, but I saw this error come up fora moment but it quickly remounted.
Kind of scared it would happen again (my alarm clock will fail if the sd card dismounted). So I had to go get an old fashioned alarm clock for the first time in7 years.

SD Card Issue in S5

Hello All,
Im Hoping Someone Would Be Able to Help me with an issue....
ive got the samsung galaxy s5 SM-G900I with telstra here in Australia, on the 26th of last month i went to my fathers wedding, i was taking photos on my phone with the camera it spent most of its time on the camera app (once closed itself down prob due to inactivity) anyways after a while it stopped taking pictures.... the capture button on screen was grayed out but i could still see through the camera.... i though ok weird and closed the app down and opened it with the same result... then a popup came up that said "Camera Failed" when i pressed ok the camera app closed.... tried to bring it up again and it was a no go so i decided to reboot my phone..... it shut down properly but never turned back on so i though ok maybe it turned itself off so i tried to turn it back on and got nothing..... i pulled the battery out and put it back in and the phone turned on and the camera was working perfectly fine again so i though oh ok glitch but all good.... anyways i went back to taking and i found that all the pics i had taken that day were gone from the SD card...
it took me a minute to relize that all the photos on my card were gone.... i went to investigate and say that the card wasnt mounted under storage and i though all good again and hit mount and nothing happened.... then i saw a notification saying either an unformatted card or an unsupported file system... i checked in another phone with it and got the same issue and it seemed the card had gone bad, anyway i got home that night and plugged the card into my computer and found that the card was reading up as a raw file system.... so i went stright to data recovery but before the data recovery could finish scanning the card all of a sudden there was my sd card reading up perfect in my laptop... which was weird to me as i havnt seen that happen before, so i backed up everything on my card to my computer and plugged the card back into my phone and it came up with a different error i think it said something about the card maybe being corrupt.... so i put it back into my computer and ran a chkdsk on it and it showed that everything on the card was corrupted..... so i decided to wipe the card and start again and i transfered everything back onto it and everything was working perfectly fine as if nothing had happened...anyway fast foward to monday this week and i went to take some photos and recorded a video on my phone (went stright to the SD card) and i checked it afew hours later because i got busy and i had found that everything i had done that day had corrupted and photos that i had taken about 4 or 5 days ago were also corrupted... images that i had seen to be working fine.... so i backed up my SD card again and though ok im gunna have to buy a new sd card and i redirected the save location for photos back to internal storage.... anyway today my SD card was still in my phone... all of my music is on it still and i was listening to music while i was heading out to the shops.... and i noticed that afew of my songs were playing for a second or 2 then skipping to the next or just pausing and throwing an error about the song being corrupt...
so i put the SD Card into my Samsung Galaxy Tab S and the songs that were "Corrupt" on the SD Card were working fine on the tablet..... so i am wondering.... is it the SD Card or the Phone?
thanks Help would be amazing!

sorry about that.... not the best when it comes to that lol, i just edited it i hope it makes it easier to read

I'm not trying to give you a hard time, but that is still hard to read. If I got the gist of your post, you had a camera failed message and apparently SD card corruption.
There isn't enough information (or maybe it's in the middle of those paragraphs) to tell what happened. Probably just a temporary glitch, but you could have anything from an actual camera failure to a physical SD card defect.
Try clearing your system cache. I wouldn't worry about the failed camera message if it doesn't recur. If it does, search for the camera failed threads, Samsung was providing warranty replacements for some early production camera failures.
If you are searching for photos, see if your phone put them on the internal sdcard (since the external SD wasn't accessible). Otherwise you could consider a data recovery app to see if photos can be recovered from your external SD card.
Is your external SD card bad? We don't have enough information to know yet? Do a search for an app to test the card integrity or you can probably use the fsck command to test the card and correct (if possible) filesystem errors, followed by reformatting and remounting the card. The fact that the card was readable on another device doesn't differentiate between an marginal or unstable card and a sound card. You'll have to test and reformat the card to really tell.

thats ok i know your not trying to give me a hard time on it im sorry that its so dificult to read, ill see if i can try this alittle better
on the 26th of last month i was taking photos for my fathers wedding when the camera stopped working, it wouldnt let me take photos so i closed the camera app and opened it again thats when i got the camera failed message
i tried to reboot my phone but it froze during the reboot and didnt start up again so i pulled the battery out and put it back in, when the phone started up again the camera was working perfectly fine but the SD card was coming up as unreconized file system or unformatted,
i got the SD card to my Laptop and the File System Read up RAW i started data recovery and while it was scanning the card everything started working again and i got all my photos back without the need for using data recovery
put the SD card back into my phone and it read corrupt so i reformatted it and restored everything back into it and the card worked fine,
Fast Foward to Monday This Week and i recorded a 10 minute video at 1GB size and took some photos.... and they corrupted.... no issues with the camera or anything like that.
Today i Was Listening to Music that was stored on my SD Card (64GB Class 10 Transcend) and it skipped a song about 2 seconds into it and another song it tried to play and failed coming up with an error about it being corrupt, ive taken the SD Card out of my phone and put it into my Samsung Galaxy Tab S and the songs that were "Corrupt" worked perfectly fine on my tablet
so im wondering if it could be the SD Card or the Card Reader in the Phone? the System Cache in the phone has been cleared.
Thanks i hope thats helped you able to understand it better and again i am sorry for my poor writeing skills

Thank you for going through that again.
The basic question or mystery that we are trying to solve is why does the external SD card only appear to have problems in your phone and not the tablet? And how can we tell if it is a card issue or something other aspect of your phone?
While it could be some problem with your phone e.g. bent or damaged SD card slot, corrupt driver or other causes.. it would be hard to track down without further hints. i.e. there are so many possible causes that we need to narrow it down.
So it's easier to tackle this by elimination. Lets test the hell out of the card because that is easier to do.. and despite the fact that it appears to work in your tablet, it's still more likely to be a card problem. Why would it only affect your phone and not the tablet if it is a card problem? There are lots of reasons, but just to give one example.. it could be a problem on just one area of the card.. and that happens to be where your phone is preferentially storing files.
If that makes sense so far.. then the plan is to see if we can identify a card defect. So.. grab an app that will check for file system errors (chkdsk, fsck, etc), check partition structure and do extended read /write tests on the card. At a glance perhaps one of these apps: Lewy or Dewy.
Most likely you have some bad clusters which fsck or chkdsk could repair. But it's best to run an extended card test.. that may take a few hours but it's still a lot quicker than trying to search for all the possible causes of phone problems. If your card passes with no issues.. I'd be inclined to back up your phone and then install a brand new, 100% fresh and stock firmware temporarily. That should in one swoop tell you if it is a hardware or software issue. Again, we are looking for expedient ways to narrow down the possible causes.

i will give u a hint ... try to make your topics, in your case, a loooooot less than your post so a lot more people would help you.

Im Sorry it took so long to reply to you, The 2 apps u suggested did not work they wouldnt detect the SD Card, i put it into my laptop and backed up my data and i ran a chkdsk on it and it came back clean said nothing was wrong with it, i have hard disk sentinel installed on my laptop and ive run a surface scan on it that is doing read write read test selection on 2 passes and has been running all day.... the first pass came back clean on it but the second pass has picked up 4 bad blocks near the end of it... its come up "7/08/2014 9:43:09 PM ! Verify error, Sector: 99480300" afew times with different sectors on it, im wondering if the camera issue i experenced could have caused my card to screw up like this? or even the phone not booting back up without taking the battery out first after the camera issue happened? would you consider Transcend a good brand for SD Cards? mine was a Transcend Premium 300X Class 10 Micro SD Card 64GB, im thinking of getting a 64gb Samsung Pro Micro Sd Card now... are those good?

Hey mate! finally i have someone who has the same issue as me! this happened to me last week. i was going through my photos and they looked to be all corrupted. i didnt take much notice as i didnt really need them. i was at the gym and my music was all gone. it was all saved to my samsung 32gb SD card. i got home and there was a message saying SD card is damaged. i lost everything. i did a format and nothing happened. it still said SD card failed.
i went and bought a new Samsung Evo 32gb SD card and it is doing the same thing. i plug it into my laptop it works fine. when i chuck it back into my s5 it says its corrupt. i have no idea whats going on. SD card reader in the phone maybe damaged somehow? i dont i have ever dropped my s5. its driving me mad.

My wife's 64GB card is now doing the same. Formatted and working twice. Images all saved to cloud but a pain waiting for it to happen again.
Ordered a new 64GB card today. Hoping that sorts the issue. If not its return to store time. Happy knox is intact.
Sent from my Galaxy S5 running NeatRom 0X1

my galaxy S5 does not read SD card also..
i think most likely is the software issue.

Just wanted to chime in here. I have a hardware failure with my s5 SD reader, and it was my fault. I had to replace my digitizer, hence putting My Straight talk sim into a temp phone for a fee days.
I cut my sim down to nano size for the temp phone, then stuck the now nano sim back in the s5 after repair, I didn't have a sim converter, and ended up bending pins. Thankfully the sim still works but I toasted my SD slot. Not only will it not read any SD card, it breaks any working one i put in it. I'm a hardware guy, so I'm going to give a go at fixing it, but I'm pretty sure the whole assembly is soldered to the board, no replacing this assembly. At least I don't believe so.

Moto X Play - SD card damaged

I've just bought a Moto X Play ( UK ) which comes pre-installed with Lollipop from carphone warehouse, I have Samsung 64 GB SD Card Class 10 which is official SD card, been using it on my old S4 phone & computer without issue However when used on my Moto and reboot the phone I get a message saying the SD Card is damaged, and I can't access anything.
If I put the card into my computer or old S4, the card is fine and can be read no issues. i've been playing around with it and what i've noticed is that I think I can now replicate this problem at will and just wondered if any others are noticing this problem.
To replicate the problem:
1. Move an App from internal to SD Card.
2. Reboot the phone, the phone will say the "SD Card is damaged, try re-formatting it" ( don't do it! )
To resolve the corruption, I just took the SD Card out of my moto put it into either my Samsung S4 or a PC, go to the SD Card and clear down the contents of the "Android" folder sitting in the root of the card.
Put the card back into the Moto on startup, the phone is happy with the SD card!, no corruption and all files ( Music, Video, Images etc ) work without issue on the moto.
Repeat the steps again and bang the card goes corrupt again!, very annoying.
It appears to me that there is a bug in the moto SD card implementation which needs addressing as I can't put apps onto SD card and re-start my phone without this problem arising.
I've tried replicating this fault with another memory card and get the same problem
Can anyone else confirm if they are having the same problem?, if you aren't could you tell me what brand of memory card you are using, and the exact software version you are on?, when I do a software update it says I have the latest version.
My Phone Version is:
Android version: Android 5.1.1
Hardware SKU : XT1562
Build Number: LPD23.118-10

Have the same with a (the one) SanDisk 128GB card...

I had the same problem with a 32gb Samsung Evo SD card, yesterday I searched for a solution on the internet and found some suggestions about to format the card from Windows with "quick format" unchecked.
I gave it a try, it took 10-15 minutes to format it but I had no more problems so far!

Hi
What I did was to buy a new memory card from Curry's, won't buy an SD card off places like amazon/ebay due to the number of fakes knocking around on there.
I got a 64 GB PNY Class 10 memory card ( £17.99 ) , plugged it into the phone ,it was instantly recognised, I decided to Erase card using the Menu option before moving apps and data onto it and everything is working fine so far, have re-booted the phone several times without any problems!
I think probably re-formatting the existing Samsung memory card in the computer would probably do the trick as well. however I've got a new use for that memory card as it's going to be used in the car sat nav instead.
It's a strange issue but i'm glad it's solved.

same problem here, can´t use SD as internal becoz it freezes at 40% of formatting and later says that is damaged.
Have the same problem with 2 or 3 sd

I found this good utility for SD Cards, download it on your PC and try scanning your SD Card with this tool, perhaps there is an fault with your sd card, it's called macrorit , I can't post a link as the forum rules won't let me.
There is a free version for download, just go to google and type "macrorit download"
This tool is also good if you need to format a 64GB SDCard as FAT32 instead of exFat, something my car sat nav wants and Windows 10, with diskpart can't do

I am sure there are bugs in both the Android 5 & 6 code but when it comes to SD cards my first suspicion is the card itself. You have to understand that these things barely work and are only marketable because they have internal processing that corrects problems on the fly. Even manufacturers with the best reputations produce flakey batches of SD cards. My experience has been that cards can have invisible latent problems which manifest only when usage changes. eg: a swath is bad but never exposed until a size boundary is crossed, or a storage allocation scheme changes with a new or updated filesystem.
Micro SD cards are vulnerable to physical handling problems including excess g force or static electrical damage.
FWIW, my experience:
1. If even one device reports a problem then the card likely is not 100%. Replace it.
2. Never store valuable and irreplaceable data on it without an active and complete backup process in place.
3. Buying an expensive high capacity device? Get the extended warranty or in store replacement extension. Keep the packaging with all of the batch coding on it. Make sure the replacement is from a different batch.
Also, there are a lot of counterfeits. Buying from a big store says nothing about the true nature of the device.
Hard drives: Very good, predictable service times
SSDs: Almost as predictable.
SD cards: Very unpredictable even if not counterfeit. Easily reprogrammed by anyone with some tech savvy.

One more thing, if the SD card is 100% ok then you should be able to completely rewrite the card every day for at least a couple years.
If your card is under warranty and giving an error in even just one situation then back it up and throw a heavy "burn in" program at it. Let it run until it dies and get it replaced. Better in a burn in program than in your phone.
When you get a new card, make sure you run a tester that writes/reads the complete capacity at least a couple of times. Make sure the data is random.
Again, my opinion only.
Never think of SD cards as being reliable like the phone internal storage. They just are not. They could be but then you would be paying a lot more for them.

I bought a brand new 32GB strontium class 10 card and only managed to use it for a day before the phone kept notifying me that the card was removed and I have to restart the phone to be able to use it again. This happened multiple times before I changed the card with my other one, bought 4 years ago, a class 4 16gb sandisk. no problem whatsoever with it. Now I'm getting a replacement for the new card.

My moto x play is not supporting Samsung evo 32 GB memory card how can I fix this problem plzz help

I have the same problem here with my Samsung 64gb SD-card. Did you find a solution? Before I tried to format it as an internal device is was using it as an external sd card and didn't met any problems.

I have the same problem Android v 6.0.1, system v. 24.61.52.lux_retail_ds.retla.en.01 retmx

I am facing the same problem.. I need to restart my phone repeatedly to get my sd card accessible and that too that becomes accessible only for a few minutes.. And then agaun the same problem occurs

I have the same issue as Shivi10.
I previously found the same issue on a sandisk (32 GB class 10) and asked for a replacement.
Now I found same issue on a new Sandisk same size and class bought on a local shop.
I'll burn in this card on a PC and see the result. If the card passes the burn in the phone itself could be the cause for me.

I used the suggested macrorit utility to check sd card integrity.
I erased, formatted the card on a pc. Then I did several cycles of write, read with macrorit, erase. All these cycles went good. The card is clearly ok (this is the second one, the first was returned but I suspect it was good).
I decided to return back the phone. Appraisal for amazon who agreed on a money back. Excellent.
This phone is awesome, but I'm tired to go around finding bugs and losing my pictures. I'll look for something else.

My problem started after I was using my Strontium Nitro card as internal memory and dropped the phone, my moto doesn't accept any card since then

Have you got the solution to your problem? I am also facing the same for last 3 month

Have the same problem with 2 or 3 sd[/QUOTE]

the issue is with the andriod / phone . i had the same issue as i twerk with electronics i had tried checking the sd card on my pc and all the data is present perfectly . I have then used a spare SD card in the phone and then removed it after config and then used the issue SD card . to my surprise it is working . this i have done multiple times . for some reason when we eject the sd card the system feels as corrupted SD card and ask for format . Hope this will save ur data if you dont format before checking the same in PC.

"SD Card Damaged : Try reformatting" and SD card randomly unmounting itself.

"SD Card Damaged : Try reformatting" and SD card randomly unmounting itself.
I'll start from the beginning. I purchased the phone on 2/14/16 from Best Buy for a $1 upgrade fee. The phone worked fine from day one with the Sandisk 64gb Ultra card I have had installed and running in my three prior phones (Samsung Galaxy S3, Samsung Galaxy Note 3, and LG G3) with no problem. Basically just used the card to hold music I had downloaded off of Google Play Music. I believe I used about 40-45gb of the available space.
This past Monday, the phone was at 20% battery when I went to bed so I powered the phone off and charged it overnight with it off to get the most charge before work. When I powered it on Tuesday morning, I had a notification that said "Damaged SD Card: Try Reformatting." Upon seeing this, I attempted a reformat and nothing happened. Tried again and again to nothing happening. Being rather upset, I dealt with the lack of a SD Card for the day until I could get to Best Buy and see what they had to say.
Stopped by Best Buy after work and their "tech guys" told me they had no clue, attempted a few fixes (all to no avail) and ended by telling me I should buy a new SD Card and give that a shot. Being it was close to closing time, I grabbed the 128gb Samsung Evo + which, per a few internet searches, was the "best SD card in 2016." Drove home, powered off the phone, pulled the SIM/SD tray, installed the new card, popped the SIM/SD tray back in, powered up and...nothing.
The phone wouldn't recognize that there was a SD card in it. Read a few articles from a few Google searches and pulled the card and verified that it was working by putting it in my Chromebook. The Chromebook recognized it, my Lenovo PC recognized it, the phone would not. I tried reformatting it on the PC and reinstalling it just for it to recognize the card and have the card unmount itself literally within two minutes of being recognized.
Frustrated, I called Verizon and asked what they could do. They overnighted me a replacement phone. Get home from work today, try the new phone and ...nothing. Same issue. I read a few threads on this forum that stated that Motorola doesn't want to take responsibility for the issue but I don't see how it isn't the phone's fault. My Chromebook can use the card. My PC can use the card. The previous three phones I had could use the 64gb Sandisk card. What gives?
Sadly, looking around Google, I don't see many articles or forum posts about my issue so I have yet to find a solution. Can anyone shed some light on this? Is there a way to fix this? Is my best option to get irate with Verizon until they replace this phone with yet another replacement to which has the same problem? Do I wait for the Marshmallow update and hope for the best? Do I continue being irate with Verizon in hopes that they'll replace this phone with a different model by a different manufacturer? What is my best options?
TL;DR - SD Card will mount in phone but will unmount itself immediately after powering on. Lack of Google results. Is there a fix?

Try to format sd card with your phone. I had similar problem with my previous phone.
I have exactly the same sd card as you and works flawlessly in my Force.

I've tried numerous times. When I hit "Erase everything" it starts and reads "Unmounting SD" for like a minute then gives me the error that the SD card was removed before it could finish though it hasn't. I don't know what the problem is.

Try removing the Micro SD-Card and use Windows to run "Error Checking" on it (right click drive, click on properties, click on "Tools" tab").
This fixed my SD-Card concerns.
