Memory card keeps getting "damaged"

If I leave my 16gb mem card in my phone without taking it out, it never corrupts. As soon as I start unmounting it and using it in my tablet and going back and forth, something is causing the card to corrupt.
Thank God I back everything up the the cloud or my hard drive at home or I'd be pretty pissed off.
Is this happening to anyone else? Any suggestions of what is causing this?

I've already replaced this card once. Either the manufacture is crap or something inside android on one of my devices is corrupting them. Maybe they aren't unmounting correctly.

Are these SD cards brand-name items purchased from a reputable vendor?
Or, are they cheap discount $5 cards purchased from a 3rd-party vendor via Amazon or Ebay?
If they're the cheap no-name $5 cards, they're probably piece-of-crap 2GB cards made to look like 16GB cards.

Try this out. It repaired my "damaged" SD car Sometimes the filesystem on the card gets corrupted. It can happen for example if the card was ejected while a file operation on it was in progress. When that happens you might have trouble accessing some of the files, loading times for some directories in file explorer may be very slow. You can attempt to fix it using the desktop windows' built-in chkdsk utility. Open up command prompt (start->run->cmd.exe) and type chkdsk /X /F <SD card drive letter> My SD card reader is X:\ drive, so i wold use the following command: chkdsk /X /F X: SD card reader is recommended, but probably not necessary because it should also work with WinMo's built-in USB mass storage function or wm5torage.
Under linux you can check/fix the card's filesysterm and in some cases undelete a file using fsck.vfat or dosfsck (single tool, two possible names). Refer to its help for more details.

I would make sure you get nothing less than a class 6 card. 1) its faster (6MB/s for class 6) and 2) the faster cards are usually better quality. Just my experience with sd cards and data integrity on them.

I have a feeling I may somehow be pulling the card before its ready. Sometimes it unmounts and disappears from the status bar on the tablet but doesn't give me the message that its safe to remove. Maybe I should wait longer. If that doesn't work ill upgrade to a class 10. I have a class 4 right now.

Wintec cards are name brand, but in the past I know I have heard about compatability issues with a few different HTC devices.
Class 6 is not always better nor always needed. It depends on the card. I have class2 sandisks that read and write faster than a kingston class6 card. Some companies over rate and some under rate. You may purchase 2 like sd card from the same company. One might be made in china and the other in taiwan. Companies may use different manufacturers which means not all cards are equal.
Also I have yet to see someone speak of it. My last phone was an HTC HD2. Very similiar specs to the Inspire. The HD2 was incapable of read/write speeds more than what a class2 card offered. So having a class6 or even a class10 made little or no difference.

My Atrix corrupted the first Wintec card as well now that I think of it. At least I think it did.
I think there's a very real possibility that im ejecting the card before its read. I may be ejecting it as soon as I see the card drop from the status bar but before it says safe to remove.

[Q] 64gb SD card?

Does the phone support 64g SD card?

Officially no, but supposedly, microsdxc is compatible with microsdhc, so you may be able to use it.

wow
64 gb! this could change everything... I could finally frag my old 80gb ipod! I dont have anyone got this yet? I really would love to know if i need to buy one, but how long would it take to scan the media card?

I'm curious if anyone ever tried this. I'm an avid audiobook listener, and have a large collection. It would be a pain to swap cards, so I'd rather have a larger one if it would accept it. I know that Samsung has said this was a SDHC phone, but other "SDHC" phones have had success with the 64GB cards. Anyone have a clue on this?

I have no clue, but you could use the Google Drive app or Google Books to store your collection - that way, you won't need a card.

That would be great, if I had unlimited data or constant access to wifi. I do not have the first, and at work, the wifi is locked with a password only the bosses get. I have a usb wifi adapter on my computer that will share my internet with my ad-hoc enabled devices, but alas, the charge does not have this capability either (unless my endless searching has missed something somewhere). So direct storage and access is my only chance (also, I have limited space on my computer, so storing and listening to them there is not feasible either.

well, you don't have to download all of the files at once - just one at a time. perhaps the night before you can sync the book you want to listen to your phone to have it ready the next day.

YES you absolutely can run the SanDisk 64GB class 10 micro SDXC card in your HD2. The phone does read the full 64GB and can access it all. You do have to reformat it first as it is in exFAT which can't be read. It needs to be formatted in FAT32. The kicker with that if you try to format in your PC, MS has deemed that FAT32 is 32 GB max and if you use the inbuilt format in any version of Windows, it will only format it in exFAT or NTFS. I also tried using a program called SDFormatter but it would not allow me to format in FAT32 either. I ended up using EaseUS Partion Master Home Edition, which is a free program. It worked a charm, and was very fast as well, Then I xxcopy'ed my SD card contents onto the new 64GB card and installed it in my phone. Both my WM 6.5.5 and my SD Android 2.2 are working perfectly, though the Android may be just a bit slower now and then. Both my 32GB and my 64GB are class 10s. I use XXcopy to keep a backup of my SD card on my computer, just in case. I update the backup every couple weeks or if I have updated anything significantly (which seems to be all the time with Android apps). I am running Core Cell Evo v4.1 and CoreDroid v.08.

Sorry I was in an HD2 forum trying to post this, and the XDA system told me there were similar messages I should check out first. I was in a rush and it never occurred to me it would look for messages in other forums. I assumed it searched for similar messages in the same forum. My bad, expected the XDA system to be smarter than that. Ditto for deleting a message. I'd gladly delete the SOB but after wasting 1/2 hour I didn't have trying to figure out how the hell you to delete a message, I just gave up. If any moderators see this and want to delete my messages here in this forum, PLEASE feel free.

[Q] 64GB SDcard format question

I ordered a new Sandisk 64GB SDcard but after reading many threads on the topic here, I have a question about the format. From what I've read, in order to have the card recognized by CWM and other custom recoveries, it needs to be in Fat32 format rather than exFAT. Many people have suggested that you can use a Windows based 3rd party software to properly format the card, but I don't have a SDcard reader on my PC so I'm not sure what my options are at this point. I tried searching the forums about posts from people in a similar situation (i.e no card reader on PC) but was unable to find anything. Any suggestions or ideas on what I can do to retain the full 64gb capacity and still be compatible with CWM without having access to a SDcard reader? Thanks very much.
Link to card: http://www.newegg.com/Product/Product.aspx?Item=N82E16820171582

Will need to find a PC to format it. It comes ExFat and not only recoveries won't see it but roms/kernels may not see it either. The program is guiformat. Can Google and find it easily. The site is little confusing. Click on the picture of the app and it will give you the download.

Thanks very much for the response. I was afraid that would be the case. I honestly don't know anyone who has access to a SDcard reader, so I might have to just end up returning it to Newegg for a 32gb version instead. Thanks again, I sincerely appreciate the info.

I thought these issues were exclusive to just the 64gb variants.
I actually dug around in my basement and found my old PC tower that has a built in 8 in 1 card reader that supports SDcards. If I can find a way to extract it from the old tower and hook it up to my new one, I may yet find a way. Thanks again for the continued help.

Yea. Only difference between 32 and 64 is don't need a special program for 32. Windows can do it natively. Good luck.

I realize this question may sound ridiculous, but I figured there was no harm in asking.
Is there any chance I could stick the 64gb card in my old Droid X, connect it to my PC, and then use the program you suggested to format it to FAT32? I guess I was hoping the phone could act like a SDcard reader of sorts for my PC. Thanks again.

I had a droid x but I'm not sure if it handled a 64gb but if it does you should be able to format it the way you want.I bought a $4 usb micro sd card reader for my SanDisk 64gb card and I hooked it up to my pc usb slot and used a partition program and was able to successfully format it to fat32.Have not had one problem with it being recognized by any Rom or kernel, think it gave me 59gb total after it formatted.

Won't work from phone but go to radio shack and get cheapest one of these you can find. May be able to get with 1GB card. Take pic and show them what you want. Sorry I been busy and didn't think about it. Good call Droid. $12 max.

So I purchased a SDcard reader, hooked it up to my PC, and formatted it with the guiformat program that was recommended earlier in the thread. I set the allocation size to 65536 and left the Quick Format option checked. However, after it finished, both Windows and the S3 only show it as a 32gb card (approximately 27 GB total storage space). Is there another formatting program for Windows or any other ideas you could recommend so I can get the correct storage size (64gb)? Thanks again.

Regardless, I sincerely appreciate the help I got from the folks in this thread and via PM. Thanks again for your time and effort.

There's another thread detailing all the issues with exfat 64gb cards here:
http://forum.xda-developers.com/showthread.php?t=1698672
I encountered the same "hiccup" as you pertaining to the 32 gb issue.
I ended up using a program called EaseUS Partition Master to finally get all back to normal. I wiped my sdxc partition, it did come back with some message that something didn't complete ???, but then I formatted as fat 32, primary partition, and got the entire 64gb back and so far... ( fingers crossed ),.. all seems to be working well.
With the card formatted as exfat, as soon as I got around 8 gb of music, photos, etc.. the card simply would loose its' file structure and just start acting weird. All files would still show up if I pulled the card and put in an sdxc reader on the PC... but my Galaxy S3 never would recover them properly.
This has got to be some kind of "bug" in the phone as you'll see in the other thread this problem is quite common.
For what it's worth.. I seemed to have much better luck transferring large chunks of data with the card in the reader opposed to hooked up while in the phone. ( speeds kept dropping via the phone cable )
Good luck!

Thanks for the info. I actually tried the EaseUS Partition program you referred to, but it still remained at 32gb. I ended up returning the card to Newegg and will just get a 32gb to replace it as I'd rather not have to repeat this process. Thanks again for the useful info. I sincerely appreciate it.

Sure... I vaguely remember I had to try to format as NTFS first for some reason before I got it to properly format with entire 64gb fat 32. I spent countless hours trying to work out all the bugs with this card and exfat. Samsung states the Galaxy S3 phone is compatible with it... but there is definitely an issue with file structure once you start loading it up.

Quick update:
I ended up returning my Sandisk 64GB and replaced it with a G.Skill 32GB (Class 10) that was on sale for $22 from Newegg. Surprisingly, it came already formatted as FAT32 so I didn't have to mess around with it to get it working with CWM and custom kernels. Seems to be working great so far, and is plenty fast, so I'm pretty happy with the end result. I guess it might have been nice to have an extra ~30GB, but I mainly stream all my music/video anyways, so I'll have a tough time even filling up this new card.
Thanks again to everyone who gave me their advice and input on trying to get my first SDcard formatted correctly. Even though I wasn't ultimately successful, I sincerely appreciate everyone's time & effort.

[Q] 32 gig SD card dead?

Hey guys, would appreciate if someone could give me some help on an issue I'm having with a 32 gig SD card (SanDisk Class 10 bought at Best Buy so it's definitely legit). Anyway it worked great for a long time, however, recently I tried to use the Gremlin Remover on my phone, it crashed and burned in the middle of the process as I've heard can often happen with Gremlin Remover. I did a restart, and after that problems began to appear with my SD card. Almost all the data on it disappeared and it started to constantly mount and dismount from the phone. I thought it might have just been the failed Gremlin Remover run, so I reformatted it in Windows, put Gremlin Remover, black hole system wipe, and my ROM back on and did a complete wipe and restore of the phone, card seemed to be working okay, but then the next day it started dismounting and saying it had been unexpectedly disconnected again. Now I can't get the phone to recognize it at all so I can't connect it to Windows to get it formatted. The strange thing is that my tablet (Asus Transformer TF300) can mount the card and read the data on it. However I can't reformat from the Asus since it won't mount as USB storage in Windows. Is it probable that the card is completely fried? Or does it maybe just need a good reformat? If a reformat would fix it, how would I go about doing it? Is it possible to reformat through terminal commands? Or some other way? Anyway thanks in advance for any help.

I too have a Sandisk class 10 uSD card that just recently failed on me. It started losing files one night, then it stopped mounting. Now it just shows up as a 30-something MB drive that I can't format. I have tried many methods of restoring it to no avail.

Maybe try to format it using external sd card reader? microsd to sd?

I think there's a known issue with these cards. I bought one of these a couple wks ago from a deal posted on slickdeals.
I haven't had any problems with mine but after the purchase I started reading comments in the thread about how these cards are known for mount/dismount trouble and high failure rates. I believe in still under my return period with Amazon so I've been debating exchanging it for a different brand like Samsung. Sorry, I'm at work posting on my phone so I can't post a link.

This has already been tried, without any luck. I tried to format via Disk Utility on Mac OS, numerous drives tools under Windows, and gdisk under Ubuntu, and nothing will revive it. Zed's dead.

I too saw a number of reviews that noted the same type of failure, so I may end up giving another brand (like Samsung, as you suggested) my business. Sandisk does not seem to want to take any responsibility for my uSD card failing after only 8 months of normal use.

That's how I was able to get my 64GB to work in all my other devices. Primary partition is one of those things I never thought about..I always just left it as the default "Logical". Figured it out when trying to use my card with the M.O.J.O.
If it works for you, let us know..I'm ready to run to Best Buy and buy one if it does.

2 or more people have reported that it worked with their tap pro 8.4 although it says it only supports 64g

Yes. That is why I asked if anybody has tried it on the Pro 12.2

Just received mine, it worked straight out of the retail packaging. Shows 119 GB free on the Note Pro. Looking at it on a PC, it was formatted FAT32 and had a primary partition on it.

Thanks for this. I know what I'm spending my overtime monies on.

☆☆☆Yes! Mine is showing 119 Gb free on the Note Pro as well!☆☆☆
1. You must format at FAT32.
2. You must set it as the Primary Partition.
Developers don't need no stinkin' signature!
If I've been able to help you, please hit the "Thanks" button.

So its working right out of the box?

Sounds like it, but if not you can use MiniTool Partition Wizard.

Can someone check if you can use NTFS? Can't copy HD movies larger than 4 GB with FAT32.

I sincerely doubt it will work with anything other than FAT32...Most devices don't. There may be a workaround, but I've not tested it...nor do I really need to as I don't have any large files to worry with.

Cant you just use a compressor and get the video just under 4gb? Ive done that before with full hd movies to pretty good success.

I haven't seen or heard of an Android device that handles NTFS. There might be, but usually problems with large SD cards that can't be read get fixed when they are changed from NTFS to FAT32.

Good to hear that 128gig card will work.
However, it must be a mistake of the software included in the tablet that it recognizes the card as FAT32. First reason is that the specification of FAT32 fs itself says that it supports up to 32gigs. That btw was the reason of initial problems with running 64gig, the only drivers around were propertiary drivers owned by Microsoft, until Samsung decided to include exfat drivers in all of their products (and also made it open source, which allowed developing concurrent fuse driver that offered support for other devices/aosp based roms on samsung, without need of touching the kernel).
If it is 128gig then IT IS NOT FAT32!!! Dont think that is is some variation also, coz Sandisk is a serious company and releasing card, which is formatted in fs that haven't been seen anywhere else, sounds impossible. I think it has to be exFAT (linux fs like ext4 will not be seen in windows by default, so it's not a good choice for default fs too if thinking on earning money on average users, who dont know what even linux is.
Mistake may result from the fact that 128gig cards were not available at all when the firmware was developed, and the programmer assummed somewhere, that the border is still 64gig, so the exfat drivers from kernel works well in general and sd is supported, but the procedures displaying its info go crazy coz the size is bigger than possible, some code fail in a way that was not expected and return wrong info.
If ur rooted, type in terminal:
su -c cat /proc/mounts
and look for type of fs related to your 128gig sd. Info given back by kernel may be more reliable that the one given by an high-level app.
Also, can anyone check what does windows say about fs on the card?
I guess it will say exFAT - and this will be a proper fs which you shall format your sd to, even if the samsung settings shows otherwise.
As i am planning to buy n12.2, would be glad if anyone checks it.

Actually it was his windows desktop computer that shows the sd card as fat32. This was released for mobile devices (many of which don't support exfat). SanDisk must have realized this and formatted accordingly. You can format any size storage in fat32. Just windows (USED to) limit it to 32 storage mediums. Even windows 8 can do it with a built in tool now.

Wonder if it is the windows who limited fat32 or is it a standard specification which were violated by sandisk.
Good it works.
And i understand that there IS 4gb filesize limit?

There is a 4GB limit, yes. And yes, in order for this to work in our tablet it must be formatted as FAT32 and set as a Primary partition. If upon purchase it is NOT formatted correctly, there are pieces of software available that can format large disks appropriately. My personal favorite is MiniTool Partition Wizard because it is free.
