Strange HD2 SD Card Problems

My HD2 worked fine for the first few months I had it, but then one day my SD card unexpectedly crashed... completely... no reformatting, no salvaging, it wasn't recognized by the phone or my computer or any other device I tried it in.
No big deal, I thought, it happens.
I got a new SD card. Used the opportunity to try a new ROM (dZenkins 1.80.0515).
Started reinstalling stuff and after about 2 days, the new SD card started losing data, in less than a half a day it died too. Same thing, completely fried.
So I got another one. This one, in less than 6 hours, has started showing the same symptoms. I'm expecting it to die any minute.
All 3 cards were 8 GB, Micro SD. Seem legit (even if they're not 100% genuine cards, its unlikely all 3 would experience the same failure).
Also, it happened on my original ROM and now on the new ROM, so I think it's unlikely to be software related...?
With this last (3rd) card, I was very careful to always plug it in to the computer as a "hard drive" and to always eject it through Windows before taking the USB out.
So, I'm totally stumped. Any thoughts?
I did some research and it seems like from time-to-time HTC phones have had a problem with destroying their removable storage cards. Has anyone experienced this with the HD2?
Living in Kunming, China, its going to be tough to get an HTC repair on this thing...

Have you tried another MicroSD Brand?

Yep, tried different brands, still the exact same symptoms.

Same here. My card last only 2 days after purchased. Same problem, it just crashed, not even able to be reformatted or read by pc. It just "gone". Now I'm using 16G, and still working on the replacement. By the way, I'm in Jakarta.

same problem here
i use 16 gb micro sd
i started to have acces troubles to some of my folders
my firts card died 2 days ago
is not recogised anymore what so ever

Contacted HTC, they said try hard reset.
Of course I already did that, no change in the problem. I hard-reset after each failure, but the problem keeps recurring.
Other people who have experienced this problem: Did changing to a different size card help? Or changing how you synced your device?

Today I gave the HTC distributor a visit. They said that they HAD ALREADY WARN ALL THE SELLERS ABOUT SANDISK PROBLEM WITH HTC HD2!
Wow, that's quite a revelation!
So, maybe next time you better buy memorycard other than Sandisk.

I've had problems with the HD2 and microSDHCs. Decided to disable the storage card power saving features on a just in case basis and haven't had any problems since (touches his wood). Purely anecdotal but it worked for me.

Answer is here !!!
Hey Guys !!! I have HAd the same problem when i newly got my Leo ... three 8GB sandisk cards were ruined .. read only 30 MB ... i have changed to kingstone 8GB and now i have been working very good using my new card for more than two months !!

yep same thing happend to me last nite . i had a sandisk 8 gig card , and try to format it though my pc and still nowt .
i wont be buying a sandisk card again.

I'm using kingston 8Gb card since ever, no problem with it.

I been using a transcend sd card 8 gig and works fine, never though the cheap brand would be so good

Me too, Using free 8G scandisk .. 2 week gone, then change another 8G scandsk 1 mth gone, then downgrade to 4G scandisk .. 2mth usage gone, now change to 4G kinsgton, already 2mth old ...hope that fine ..
but my old Tytn II, from already 3 years old ..the 2gb kinsgton never let me down ...
Is it the phone structure cause the Sd card burn??? if I not wrong the HD2 processor is under the memory card ....

Reformatted card in my NIKON
Hi, I have had the same problem with my 16Gb SDHC card in HD2. Neither Windows or Linux could reformat/read/write the card correctly.
Tried my camera (nikon) which can reformat the card. Success!
Still the card failed when i copyed the old rescued /backup contents.
Then I removed the exchange sync to the card and moved the thousands of pictures and videos (Camera folder) (renamed folder).
And now the card seems to work again?!?
now I am able to take pictures and videos without getting a corrupted card...

hi,i'm from nanjing,china,maybe you got three 括容卡,i just buy two cards which were you described. Now i am using a real 8G kingston SDHC card and a 4G card

this problem also happen to me, twice ...sandisk and transcend 8G...now still looking the best SDHC for my HD2

If you were using WP7 then switched to Android than the WP7 is the problem. WP7 formats your SD card with a funky format, I forget what it is called. You see WP7 uses the SD card as the internal memory, WP7 native devices also do this to as they use SD cards for internal memory. Anyway the easiest way to fix this is to SD card in a adapter and put it in a digital camera and formatting it then format it on your computer with Fat 32. The digital cameras can remove that funky format and you will not have to get special software to do it.

Stupid WP7!!!!
I destroyed 2 SD cards so far within 1 day. It happened when I installed that new updateable YukiXbmod Windows phone 7.5 ROM. It just RUINED my Stock 2GB Sandisk and my 8GB Transcend!
I really hope that it isn't the phone f*****g those Sds up! Otherwise I don't know what to do!
---------- Post added at 10:22 PM ---------- Previous post was at 10:09 PM ----------
Pls if ANYONE else has issues related to this ROM or WP7 in general tell me if you have a solution!
EDIT: I feel stupid... My SD cards are both functioning and they are NOT ruined. They are only locked by that WP7 ROM. I find it embarrasing I missed out on the part with the 1:1 chance of locking your SD.
EDIT2: And it's quite easy to retrive the cards

I had 2 8Gb cards 'killed' by Xbmod Yuki Mango + Gingerbread Android off SD. One card lasted a week before just dying. Had it formatted in Nokia N95 phone, but even though the format went ahead, the message read that the card is locked and demanded password. I formatted again, after which it was no longer functioning at all - nothing could be done. So I got it swapped for the same, which lasted 2 weeks - the same story - it just died. When I came to the shop to see if they'll swap it again, they questioned the chances of 2 cards just failing within a short period of time like that. Now on a third card, different brand, but if it goes, I say it's the ROMs, not the cards.

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
Sent from my SAMSUNG-SGH-I337

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
Sent from my SAMSUNG-SGH-I337 using xda premium

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

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

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.

Strange external micro SD card problem with Moto X Pure 1575, please help!

Similar issue like in this post:
http://forum.xda-developers.com/moto-x-style/help/sd-card-problems-moto-x-pure-t3447789
But even worse. The external SD card suddenly vanishes from phone, now it only shows up shortly after phone re-starts, then the external SD card will disappear again. Don't know what's wrong. Then I put a new SD card, it happens like that after I used it for two days. The external SD card is used as portable storage.
When I tried to format the SD card when phone just started, it fails to do so, then it disappears.
I took both SD cards to Windows computer, they show up correctly and I can copy the files out from them. However, I cannot format them, they give out error: the exFAT card is writable protected. How a micro-SD card is locked for writing?
Tried to search online, but couldn't figure out how to solve the issue. It seems to me the phone has some issue with the card and changed the card somehow.
Can anyone help?
Thanks a lot!

I've had similar issues with SD cards that were going bad - weird, inconsistent behavior. Do you have another SD card you can test the phone with to confirm it isn't a rom or tray problem?
I once had a card that would work fine in TWRP, fine in a PC w/ adapter, but just show up as removed and added over and over again in a rom. Had another that could be read, but not written or formatted. It was full of music, but music players could only play about 5 seconds then they'd skip to the next song. Both of these cards failed in short order after starting this flaky behavior.
Based on my experience, I'd say recover your data and RMA if it is an option. Having microSD to supplement storage is convenient, but those things are cheap for a reason.

Thanks, I've tried the second one(which works perfectly before I put in the phone) already, it ends up as the same bad state. I am afraid to brick the third SD card I throw into there...but I will try another one later.

I should have read more carefully. I wouldn't throw a third card at it if you've already tried two and had the same result.
Is this with the stock rom?

Yes, stock ROM, but I did root the phone.
I tried to contact Moto support and request a repair, funny enough it didn't go through because I don't have US address, which I did and put it right there!
For test, I put another small capacity card in the phone again to see what's going to happen...It might be the card, but two cards in a row...and they are different brand...Anyway, Lexar card will replace my card without trouble. But I still want to know if it's the phone's problem...Will see.

Be interesting to see if the small card behaves. If it is <32 gb it is probably fat32.
Some of the problems I described above started after letting an old phone format a high capacity card that started out as exfat to fat32. Some people say they do it and it is not a problem, but I tried formatting one 64 gb card from exfat to fat32 and broke it twice. Once using a phone and the second time using a laptop and gparted. Manufacturer did replace it both times. Left as exfat I'm still using the same card in my XT1575 several years later.

Just thought I would chime in and say since you unlocked your bootloader moto legally will not offer a repair unless you pay for it since you're warranty is now null and void.

Now I put 4GB card there, it works fine now, need to wait for a few days. My original cards are 64GB, both were formatted as exFAT, now both say being locked fro writing(what...the micro SD card is locked for writing...I want to know how...)

SO SD Card Issues

So I got this phone a few days ago. I use jet audio plus for my music and have about 30gb of music on my SD card. Pulled the card outta the old phone and put it in here. It reads it fine and saves all my photos. I noticed that the music app will sometimes go blank for a minute and my playlists will empty. After a few seconds, the music all comes back like it is rereading the SD card. First thought was maybe a problem with the app so I emailed the dev and they told me to troubleshoot and see if it happens with music not on the SD and then try music on the SD on Google play music.
Problem did not occur with music on internal memory. Problem did happen in Google play music. So then I checked my photo and noticed the galleries do the same thing and go blank for a second and then reload.
The memory card is maybe 2 months old and it's a higher quality one with a good speed rating. Before I was gonna reformat it, I figured I'd check online and see if anyone else reported an issue. Sure enough, I see samsung.com has a topic in their forum and tons of people are complaining about the same issue with many different sizes and types of cards. I was surprised that this wasn't posted here yet (at least from my quick searches).
Anyone else experience anything similar? Any feedback? News?
Auto correct changed S8 to So in the title*

Still no update on this issue. Thread on Samsung forum is 8 pages long of people troubleshooting, so far no solid fix. I'm not (knock on wood) experiencing the random reboot issues that others are. Perhaps those who are should download SD card monitor and see if their card is going crazy too.

All I can say that when my card started disconnecting like this on my previous Samsung phones, it went bad withing few weeks, I mean bad like not able to access it at all. If I may suggest, do full back of everything on that card, also check LOST.DIR, if anything is there you already have some files corrupted/lost. I don't know if this is SD card issue or phone error corrupting the card, but I lost about 4 cards this way over the years, but nothing recently and my S8 works fine.

Try backing up the card and reformatting in the new phone. I had a similar experience going from the s6 to the s7. No issues with s7 to s8, so far, though.

I've had very bad experiences with memory cards and cell phones. To be fair though, those were crappy memory cards I'd bought and I certainly got what I paid for. Now with this new 256gb Samsung EVO card, I'm hoping good things for it. Reviews certainly paint it in a good light.

I'm running the Xtreme level SanDisk. I am worried about the card being burnt up, but I don't know if it's the problem. Tried other cards like other people have in the topic I posted, same results.

I just want to say that I have personally have had VERY bad luck with SD cards I get off of Amazon. The ones I buy at a store never suffer such issues.
This is just my own personal experience, others may differ.

Issue still on going. More and more people reporting this on the Samsung forum.

Have people tried formatting using the phone? I haven't had a problem yet.

I formatted a Samsung 64gb ultra as card that I got from target with my phone. It disconnects. It has nothing to do with Amazon, or cheap sd cards.

One thing I thought of, make absolute sure the card is seated flush in the holder. Sometimes a corner will fight its way out. I put it on my desk and lightly pressed until it clicked. Obviously you may have too but I'm just trying to think of things before blaming the card reader in the phone.

Yes, people have tried all kinds of trouble shooting. A lot of people formatted in the phone and on the pc

Yeah right after I made my last comment I went and checked that. It didn't go back in until it was as flat as possible. It seems to be working so far. I also polished the pins with brass polish to ensure a proper connection. I'll come back later to update if everything stays okay or not.

Having the same sd card problems with my Sprint S8+. Sometimes it reads it and sometimes it doesn't(ghost icons) with constant different sd card notifications .
It's a new 256gb samsung evo pro card that came with the $99 immersive bundle from Sam but tried my 64gb pro card out of my Note 4 and same thing. Of course tried formatting,reseating card and sam support said it had to be encrypted which was no help.They did give me a ticket and label to send it to them for repair.'
Now the question I have.......are there people that are having NO sd card problems with putting apps and folders and such on it ????Wanting to know if it's a possible bug/software problem that will have a fix or a hardware problem with my phone and think that I should send it in. Never had any problems like this with my Note 4!

My sd card seems to be fine after reinserting it.

I have not come across any issues with my SD card (Samsung Evo 256GB) on US S8. No error messages what so ever. Actually kind of surprised, since in the past almost every Android version update brought some new permissions and messed up some form of SD card access. The messages about removing SD card is not normal and it will corrupt SD card if it happens during write cycle.

Did you encrypt your micro sd?

No apps. Hundreds of folders, thousands of files. SanDisk 200 gb.
I am getting some strange issues related with write permissions on micro sd with some apps. I think are related with encryption. I am testing.

No encryption, I don't believe in full encryption, most of the stuff is pictures and videos which don't need to be encrypted, for things that need to be secured I use secure folder or encrypt the file itself. Also I don't care what anybody says, encryption increases usage of CPU, slows it down and uses battery. It also increases the risk of corruption and file error and in case of some errors there is no way to access it from computer to recover data.

Update: disabled micro sd encryption today and write access permission issues seem to be solved so far.

Sd card disconnected again. So obviously the slot is loose garbage. I put the phone in my pocket while listening to music and the music stopped. I pulled the phone out and the sd card was unmounted. The sd was a huge reason I went with this phone and It's ****!
