storage card disappearing

Anyone have trouble with their storage card disappearing and reappearing? I hae a 1GB Sandisk. If WMP is active it will randomly detect the card is inserted and ask to scan it for media.
I saw another thread that listed several apps that might cause this (magic button, resco, ???). I don't have any of the ones listed but I do have 100 other apps/games installed either in ram or on the card.

I have had this problem before as well. I have the same card that you have and when I took out my miniSD card and re-inserted it, the card would not show up. I tried several soft resets with the card in and out of the device after the boot but no dice. I had to hard reset to fix the problem quickly.

I had this with a few months ago. My nightly backup would fail cause the SD card had gone AWOL. Sometimes if you took it out and put it back it would come back but this wasn't reliable. Since I upgraded to Faria's 3.2 I haven't had the problem so I know its not a faulty SD card.

Tytn freezes because of micro SD card, help!!

My device switches on by itself and then crashs with the screen on, it is not possible to access any thing and the only thing it responds to is to do a soft reset.
The only difference between now and when it was working fine is the usuage of a micro SD card. My device works perfectly when there is no SD card installed, if I install a SD card the device starts to show the stange behaviour straight away.
The SD card which I am using is a 1 GB Sandisk card. What do you think? Do you think it is a device hardware problem or what?
Thanks in advance for any offered help!

Have you tried reformatting the card in a PC card reader? FAT32, allocation size of 512. and make sure contacts on card are clean.
Mike

I did that already but with no improvement. What I don't understandis, why my device switchs on by itself, as if it detects a new SD card inserted while it is off!!
I don't want to be fast concluding it is a hardware problem, it is still under warranty, but I would like to send it only when I am sure it is hardware problem!

Need to establish if it's the card or device. Don't suppose you can access another card?
Mike

I have only one card, it seems I will have to buy another one, just to do the test! I will do that today in the evening, unless someone has better ideas.
thx

There's a bit discussion going on already... see this thread: http://forum.xda-developers.com/showthread.php?t=294324

Well, I had some similar problems. Now I make sure that EVERY application & service running is on the main device memory (RAM). eMail attachments, browser cache, all today add-ons and all applications that run with a schedule (like Backup etc.) - Only documents, Tomtom Maps and Games are left on the SD card. Reduced freezes to one in a week.
Well, and I just ordered a Kingston card and will compare it to SanDisk. Both 2GB.

I tried another 512 Mbyte card, it seems better so far (only since 1 day). I didn't have any freezes, but the device wakes up by itself from time to time, although the option to wake up when a key is pressed is disabled. I can't understand this!!

Kingston 2GB card working perfect so far. Running WM6 (check my signature).

HD2 destroyed my SD card?

Hello.
After trying the android booting, for 5-6'th time (all working), now the phone can't see the SD card. I thought it was only on the phone, but when i insert the card, in adapter and connect to pc, then NOTHING happens. Like if the card wasn't there.. Hmm, any clue? Usually I just formatted. But now, I can't format a SD card which "isn't there."
Please.

any one??? :S

Sounds like your sd card maybe corrupt, they can die for no apparent reason, its happen to me twice in about 4yrs, tho i always buy from CEX they offer a 1yr warranty & just replace it if its within that time.
There's been a few threads about this;

What is the brand of the memory card?

hey dude,i got the same problem as yours few days ago..cant do much abt it,i just buy a new one..some says the htc that makes the sd card problem

Hi,
My 8 GB sd card lags when i`m scrolling in the file manager.
In addition, the sd card drains the HD2 battery. I loose 35% in 6 hours in flight mode, but only 4% when not in flight mode without the sd card... ( this also yields for the original sandisk 2 GB sd card that was supplied with the phone).
Anyone experienced the same issue?
Is this hardware or software related, and can i fix this myself?

Error check your microSD card using your computer then switch your phone off, put the card back in it and switch your phone back on. The phone will need to index your music/video files etc so go to the relevant tabs and let it do its stuff. See how that helps.

i got a new HD2 and it came with a MicroSD card. I put a couple of cooked ROMs on it and everything was fine for about a week and then the card jsut stopped working. I didnot use it on any other phone or on my PC and it just died.
I own an HTC Hero as well and i put the card in it but it wouldnt recognize it. It has never happened to me before. Never has a card died on me.
I think its a problem with the way the HD2 accesses the SDcard. I wouldnt know specifics but this is the first phone that fried my SD card.

Hey guys, I had the same issue. The SD card stopped working and cannot be formatted now via computer.

My experience with Windows Mobile is that the SD/CF driver is the weakest link. The problem seems to be simultaneous accesses drive it bonkers. I've had the disappearing card problem on other PDAs but usually removing it, doing a reboot with it out, and then inserting it after the reboot is complete will fix it. If it doesn't show up immediately DON'T do anything for a while, it could be doing a CHKDSK on the card, and if you mess with it it will screw it up worse.
Once it shows up what I would recommend is hooking up via USB in CF Disk mode (not Activesync) and doing a format on the drive from Windows.
Last night I got a new 32gb Class 4 MicroSD from China (unnamed) and stuck it in, worked fine, so I backed up all my data to my 'puter off the T-Mobile Class 2 16gb and changed to the new 32gb SD. I started the copy and after a while went to bed.
This morning I got up and it had died during the copy. It was giving me an error on the new MicroSD. It had copied about 75% but was asking to continue or skip. I ended up having to cancel it because it appeared full but it was not. After a reboot I found a ton of FILEXXX.CHK files which indicated it was doing a chkdsk.
Looking at it with SoftWinter.com's Storage Tools the disk was formatted with 512 byte cluster size, way too small for such a large disk, so it was not really out of space just out of cluster nodes. If you have lots of files (I had 10,000) each takes up at least one, even if the file is only 5 bytes. So I reformatted it from the 'puter to 32k cluster size and started the copy over. Seems to be working better now.
Please note that using larger cluster size also will help performance when writing and reading large files as it has to do less directory accesses. Small cluster size is good if you have a lot of small files as it doesn't waste as much space. You lose on average 1/2 the cluster size for each file, as the last node is almost never full.

Hey
i hope for your sake im wrong, but as far as ive been able to find out in my own searching, only san disk has released a 32gb micro sd & its only class 2.
there has been a lot of talk of fake 32gb micro sd's from china, most are actually 4gb re-programed to read as 32gb on your phone or pc, but when you start to fill them with files more than their actual capacity they will only overwrite prev' files & become corrupt.
i actually pick up 1 (32gb) last weekend from a local store, tried to copy the contents of my 16gb, 7gb copied then an error occurred, 2nd attempt 9gb copied but files unreadable by phone or pc, fortunately i always buy from this store & they refunded (£50), straight away, still have 2 16gb cards ive had for about 9mnths with no probs.
there is another longer thread over in the Q&A section, you guys may find some useful feed back over there: http://forum.xda-developers.com/showthread.php?t=646731

Well, the one I got says SanDisk and I have done a full format and surface analysis, it checks out, but I am having trouble writing to it. Not sure what is up with it right now. I knew it was a fake but I thought it was a real fake, not a piece of junk. I hope you are wrong.

I´ve got problems too. I have two SanDisk 16 GB microSDHC cards and both of them are giving similar problems.
I´ve got my HD2 a few days ago and initially I used my old 16 GB card I bought with the X1 (then used with my TP2 and latest the HD2). Everything was working fine initially but then the problems arose. Now I have those problems:
1. Audio Manager has problems reading my music library. iPlay can read it though. Windows Media Player takes a long time building my music library but manages to do that eventually.
2. HTC Album can read my albums sometimes - sometimes not.
3. Resco Photo Manager can read the albums but sometimes it takes a long time to do it.
4. The computer can access the card without any problems after formatting and it seems not to be any problems reading or writing files to it. Installations of cabs stored on the memory card works.
5. Total Commander can access the card without any problems but takes slightly longer time than before to show all folders.
6. Running chkdsk in Windows gives the result of a perfectly working card.
7. The phone is draining battery in an abnormal way with the card inserted.
8. Flashing ROMs from the card worked initially but not any longer. Now it shows the threecolor bootloader screen instead.
The interesting thing is the fact both of my 16 GB cards has the exactly the same symptoms. I will try them in my X1, TP2 and Vivaz later to check out their behaviour.
When I inserts my old 8 GB card (everything made by SanDisk) everything works without any problems. Flashing ROMs work normally etc.
I´m running the Omega XT 3.0 and are using HardSPL3. The 16 GB card has worked perfectly initially with this ROM and HSPL so I don´t think they are related.
The whole thing seems to indicate some kind of "incompatibility" between the phone and the 16 GB cards. It´s like it is unable to handle that size of card correctly. It seems like it "trashes" the file system. My older 16 GB card started to behave badly which caused me to buy a replacement and now that replacement has the exactly the same behaviour.
My 8 GB card is an "ultra" SanDisk card. The troublesome cards are Class 2 cards. I began to have the impression the problem is some kind of issue with Class 2 - because the cards itself seems to be working after formatting.
I have formatted them with either Panasonic SDFormatter and the Format SD application on the phone. Both options gives the same result.

HD2 fried my 16GB card?

Ok, I have SPB backup to backup my device every morning at 2am. I have been doing this for the past few months, with no problems at all. Anyway this morning I woke up, and there was a message on the screen saying "backup unsuccessful" but the HD2 did soft reset, because I seen the splash screen for a few seconds.
Anyway I noticed that the wallpaper was not showing, and didn't think anything of it at first. But when I tried playing some music, my device didn't show the Micro SD card as being installed. So I popped the card out, and back in, and still the HD2 couldn't read it. Also under the "SD card & phone memory" it shows no SD card installed, even though the card it in the HD2.
Got home, and tried putting the Micro SD card in my PC, and even my PC won't read the card. Don't get any error messages, put it just shows nothing?
Bit gutted about this, as I had my last 3 backups on the SD card, along with other documents I need.
Suggestions please?

seems the hd2 is hard on memory cards. I scan and fix mine about 3x a week just to be sure. Since then I haven't had any problems.

My memory card would not allow me to add anything on to it.,.,pics I took wouldn't save and such.,I even tried it in a digital camera with the same results. I couldn't even format it on my PC.,just gave me an unsuccessful reply. One thing I did notice was I couldn't move certain stuff off the card (I think it was in opera) it would show me the file and when I tried to move it off the card it said the item no longer exists.,or something along those lines.,(sorry I'm at work and it's been a while since I have had this happen..,I could always reattempt and post results if you guys would like) I threw in an 8G card and everything has been fine.,but would really like my 16g card back

Gonna keep that in mind. Purchased a new 8GB card, but had to restart my phone from SCRATCH!

Hi
There is a quick link to find out if you cards are real or not? I cannot post this link , but Google detecting usb counterfeit drives.
I know a lot of people buy cheap from ebay etc, and few are real good copys. Always remember to buy sealed branded makes with the class in the circle (2,4 or 6)
Living here in Thailand i know all about the copies!! I bought a few, and yes they were copies not 8gb, but 2gb. so at least with the link above it can keep you right.
Also when you get your new real card, erase it in you mobile, then format it before use.
I back up my SD to my D/Drive, but i unhide and show all files on the main computer to make sure all files are transfering over, including the hidden ones.
Just a few tips lads.

Hi, My 2 MicroSdHC 8GB Memory card experienced the same. 1st card only work for 1 and a half day and the 2nd card only work for 1 day!! It's showed NO SD CARD on my HTC HD2 Leo. I bought both card on Ebay. They sent me the replacement card. Unfortunately both card are same. They claimed that they are selling 100% Genuine Micro SD Card!! Lucky I am getting my full refund from them after open a dispute!! Now, I am trying to get other 16GB MicroSDHC for mh HD2 Leo. Hopefully the new 16GB card work well with my HD2 Leo.

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.
---------- Post added at 12:46 AM ---------- Previous post was at 12:33 AM ----------
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.

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

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.
