[Q] Issues with SD Card

Hi everyone,
I am having an issue with my SD card and hope someone can help.
I have bought an SD card for my HTC Desire HD. This is a Lexar (High-Speed) 32GB Micro SD-HC card. I have had this for around 3 months.
All has worked well until recently. I have been unable to sync and access anything on the card. For example, I use root explorer on the mobile to view all of the files within the SD card. This has worked previously, but recently hasn't. When I try to view the SD card files the app crashes.
Also, when I try to sync any files to the mobile using HTC sync, the sync seems to progress and complete according to my PC, but nothing seems to be available on the SD card. I tried to sync music files to the card, HTC sync carried the sync out to my phone, but nothing is showing when I use this with any music apps.
I am now constantly receiving messages on my mobile asking me to download my language pack again for my SMS application. I may also receive a message saying the SD card is read only, press here to fix. I have tried to press this and the SD card seems to be re-set but doesn't actually fix anything.
I have also tried to format the SD card through the phone. Have taken the SD card out of the phone and re-inserted this. Still no luck.
Does anyone have any idea as to what else I can possibly do or is this SD card basically become faulty and I'm going to have to replace this?
Any help and suggestions are much appreciated.

I think your SD card just became problematic, and maybe soon it will become unusable too. Maybe you should try replacing it if it still in warranty time. (life-time wrranty?).

sd card
Maybe your card is broken. You'd better buy a new one.

Have your tried to read your SD with your computer?

Lexar
I don't want to extrapolate from my Lexar SD Card to every other SD Card of the same brand, but my Lexar 16 GB class 6 card had a lifetime of roughly 3 months, too and then started to make problems. Coincidence..??
I had a case of total data loss including bad sectors etc...
Even reformatting at the PC and doing a chkdsk helped only for another few weeks, then the first bad sectors re-appeared.
I changed now to a SanDisk which was much cheaper and is faster anyway, despite the fact that it has no class XX defintion printed on. ;-)
But regular backup is your friend, anyway, nandroid and titanium saved my day, at least to 90% of the data.
cheers

Yeah, I can read the card on my PC. I try to add files manually on to the card (without HTC sync) this adds but when I try to view with the mobile and doesn't seem to show the file. I then try to read the card again and the file I have added has gone.
Thanks for the help guys. I think I'll buy a new card and go for sandisk. I'll try and find one with a good warranty or lifetime warranty. Anyone got examples of cards or suppliers who provide a lifetime warranty?

[Q] SD Card problems

Hey everyone,
I've been looking everywhere to get some help with a problem I have with my 32GB SD card.
I'm using an Xperia Play (R800) rooted, unblocked and bloteware removed. Whenever I try to move files, I use one of 2 methods:
1) moving files by connecting the phone to my PC via USB cable and dragging files
2) unmounting the SD card from the phone and use a card reader to move files
In both cases, no matter how I try or how I move the files, eventually the phone will either freeze / freeze + reset / reset / or everything combined several times. Once the system boots up again, it restarts itself several times while trying to read the memory card.
This is really frustrating because it happens to me for the past 4 months, ever since I bought the phone and tried working on it. No matter what I try to do, I always end up with this problem, which eventually leads my SD card to randomly delete files. This includes music, transferred PSX games and such. It's really bugging me, and I really need some help.
If anyone can help me out, I'd deeply appreciate it.
Thanks a bunch in advance
NOTE:
The card was later formatted to 2 partitions: FAT32 and EXT2. This DID NOT help, so re-partitioning my card won't help. Think of something else.

Repartioning your sdcard over and over can result to data loss. Why did you have 2 partitions? You should only be using FAT32 as your primary partion.

I only did that once, and it doesn't have anything to do with the data loss as this happened before I partitioned the SD card. I have 2 partitions for Link2SD app. And even if I do have FAT32 as my primary partition, it still deletes my files at random...

I have 2 partitions for same reason as you Link2SD! That should not be a problem.
Couple of questions
(1) Is this a new SD card and have you used the card before on other phones (Could be a fault with card try different SD card)
(2)Have you been on the same rom since this problem started (If yes i would try a different rom could be a software problem.)
I would try these options to narrow down what the problem is seems like you have tried all the partition and formatting options already :fingers-crossed:

To answer your questions:
1) This SD card has not been used on other phones since this is my FIRST smartphone (took me a while to move to the next step )
2) I never use roms, only the default stock rom.
I find it hard to believe that the SD card is the problem, but what do you think?

I think only way to know if SD card is to blame is try another one,there are apps on Google Play that can test SD card but I don't know how reliable these are.Also you said you deleted bloatware did you delete something you should not have?It would be good if you could try another card then you would know for sure a smaller SD card just to test?

Well, oddly enough the problem WAS the SD card all along! I've been trying a new SD card for the past week and everything went smoothly.
Funny, but the solution was only to replace my SD card.
With that in mind, I'm changing my question. I guess there have been many posts about it, but I'm going to ask this anyway:
What would be the best SD card for the Xperia Play? The bad one I used recently was a SanDisk 32 GB Micro SD card, and the one I'm using now is a small sized 8 GB.
Can anyone help me out on this one?

The best sdcard for the xperia play is a Sandisk class 4 or 6 sd card. Preferably stick with the class 4.

Thanks for the reply. Do you happen to have a link to a thread that can prove your point?

To prove my point? Your the one asking for help why dont you research it yourself.

You didn't understand me... Thanks a bunch though
As far as I'm concerned, this thread is closed.

[Q] [Pro] Problem with new microSD card

I've just bought a brand new 32GB Class 10 microSDHC card from SanDisk, but I'm having terrible trouble with it in my Xperia Pro.
The symptoms are that, if I move apps to SD (using the built-in method in Gingerbread), they will start force-closing. Files stored on the SD card sometimes won't copy from one folder to another. The terminal shows "I/O errors". Eventually the SD card will seem to disappear completely from the system. Sometimes the whole device will spontaneously reboot.
If I put back in the original 8GB Class 4 card, everything works fine.
I am sure the 32GB card is genuine and it works fine on a PC (tested with h2testw). I have tried re-formatting it in both a PC (using Windows and Linux, and using native OS methods with various cluster sizes and with the SD Card Association app) and in the device. However I format it makes no difference.
I haven't yet tried a different ROM on my Xperia Pro (I'm using stock Gingerbread at the moment, although I have rooted it).
Do you think a different ROM might help? Or is it just that this card isn't compatible with the Xperia?

Default [Q] [Pro] Problem with new microSD card
:crying: Hi see you have tried the re-formatting option this is good because first thing people start suggesting is re-format option lol.There can be a number of things wrong and I have seen many post's with same problem as you(and after trying lots of options it does boil down to a faulty card) Even when the card as been tested.Not saying that is your problem but it is strange your old card works and also this being a new card so untested on other phones etc.It would be good if you could test on another phone although this can be unpractical I know everyone as not got a spare phone.
Also as you suggest could be the rom follow the link below this might help
Try this option link http://forum.xda-developers.com/showthread.php?t=1010807 it may help:good:
With regards to moving apps to SD card I have always found using the app link to SD the best solution for me it as never let me down.Only thing with that you need to partition your card with minitool but it is well worth it because you can link apps with widgets without any problems.
Just a few suggestions maybe some others have some too:good:

[Q] SD card not letting me add or delete files

I've been spending waaay to much time trying to get this phone to work as I had expected with previous phones (even my LG G2x) giving me less problems. I recently bought a Sandisk 32gb, class 10 micro sd card and after transferring old music, pictures and videos from my old LG G2x with a 16gb card, placing files from my computer back onto my S4 with the 32gb card is a nightmare! Photos are transferred but too out of order to try and deal with although it's more the music problem that has me bugging. I have some success after putting about 3gb or so onto the new*32gb sd card but after that, the sd card flips out and starts using special characters for file names. Below I attached a screenshot of what I'm going through with another app called V1 Golf for Android. I'm stuck and any help is much appreciated. I can't delete anything on my sd card nor can I add. I've reformatted this card about 4 times now without success. Some say that a Sandisk have been nothing but problems for them, you think a Samsung card could be the fix?
I'm also running windows 7 on my computer as some people have said that could interfere with the transfer but it seems like that's not the problem being that downloading apps from google play shows corrupted files depicted below.

First, did you format this 32gb sdcard using fat32, exFAT or NTFS or ?
If you did not format it with fat32 then that could have caused the problem.
First you need to remove the card from the phone and plug it into your
computer using the adaptor which came with the microsd card so it can be
tested and repaired in windows.
Once the card is plugged into the computer and it's recognized by windows make note of the drive letter.
Then open a cmd prompt in windows by going to the start menu clicking on RUN then type "CMD" and click OK to open the DOS prompt.
Then in the black DOS window type: chkdsk E: /F then press "enter" to scan and fix errors on your microsd card.
NOTE: The E: is just an example, check the actual drive letter of the sdcard which is plugged into the computer.
Please note, doing the above will not delete any files or folders unless they are deemed unusable and cannot be fixed.
The chkdsk will NOT not format your microsd card.
Good luck!

Unfortunately I ran into a very similar situation with a 64gb SanDisk card. After several months of using it successfully without issue, out of nowhere some 20 gigs of data were stuck. It seems that 1 file in a nandroid was corrupt. After formatting, re-partitioning, deleting etc, etc. with Windows 7 as well as MiniTool Partition Wizard I was unable to ever get the corrupt file to delete. Thus leaving the $60+ card useless and a prime candidate for the trash. I chalked it up too a "bizarre" instance. I have since purchased 2 64gb cards, one to replace and one for my new S4. Haven't had the issue since (knock on wood). Not sure what the exact culprit was, the recovery? (TWRP), a freak occurrance? or Just a defective card? If you have any luck saving your card please post how you did. Although I realize this probably isn't helpful except to know your not the only one.

My sd card seems to be stuck.
About 20 of 64 gb being used.
Now I can't delete anything. Or add anything.
It appears to delete and then it just comes back.
Does that mean my sd card is dead.

scandisk 64gb
Had the same thing just happen to me. Transferred a few kernel files yesterday and today couldn't delete, add or format anything. I was able to copy all files to computer but that's it.

same thing happen to my sandisk 64gb class 10 microsdcard as well
is it a virus?

I had the exact same issue with a San-disk 64gb micro sdcard, I contacted San-disk, they offered me a replacement card.I suggest you do the same, hopefully they will exchange it for you.

You can use another SD card to try whether this sd card is dead.
If anothe SD card can delete files, it proves that this sd card is dead, vice versa.

Did your problem solve? I'm experiencing now like with your problem. And I'm looking for an answer.

[Q] tab pro can save to some sd cards only

Hi guys.
let me say first that I am aware of whole writing/permission issue with KitKat.
And I am happy to use the build in file manager to copy stuff around.
But as I had some issues with my sd card(files were copied then dissapear etc) I bought Samsung! Sd card Class10 32GB and to this card i am not able to write at all!
I can format, create a folder but that's about it. Not able to copy anything using the 'internal' file manager.
Everything works fine if I can connect the card via OTG.
Any ideas? As i am stacked now with 2 SD cards I cannot use.
And btw with all this write restriction explanations. Why I cannot write to internal card slot only?! If it is OTG I can do anything with any application. Somehow all the explanations I have read do not add up in this part.
Any enlightment highly appreciated.
Cheers

Sounds to me like you bought a counterfeit /fake MicroSDCard , if you purchased it off ebay then chances are it's a fake. the packaging looks identical to real Samsung products and it is very hard to tell the difference.
Do you have a card reader for your pc, you can do a test on it to tell if its fake, there are several programs that can do this but the most popular is H2testw .
Take a look at these threads for more info
http://forum.xda-developers.com/galaxy-s3/accessories/samsung-micro-sd-cards-beware-fakes-t1727546
http://forum.xda-developers.com/general/accessories/fake-samsung-evo-64gb-micro-sd-cards-t2852818
The issue you are describing where files just disappear is a telltale sign of these fake or counterfeit cards, usually the cards only have about 2GB of writable space and the rest is bad memory.
Btw on a side note: I have no problems on my tab pro 8.4 , I have every single GB of my Sandisk 64gb sdcard filled. and have no problems with it..
