Got A-Data 4gb card yesterday and it worked initially until it started to look strange when I was transferring big files unto it. Seems like I couldn't end the transfer and on it appeared a catalog named xxxxxxx.xxx. I disconneced tilt during this transfer and neither tilt no Dell 1420 with SDHC reader can see this card anymore. Nothing happens at all when I plug it in. I hoped that reformatting will work but Dell doesn't see card even in disk management tools (Vista). Regular size SDHC card is read by dell just fine.
Card hardware failure or filesystem problem? Thanks!
I have experienced this issue as well with both a 2GB and an 8 GB card. I have noticed the corruption mostly happens when I take the cards out to transfer big files using a USB reader. Do not touch the surfaces of the cards, handle them by the edges to minimize the risk of losing your data.
Thanks, I will remember that but if card is not seen as a drive by PC can I still return it to workable state?
You will likely have to format it with FAT32. Obviously your data will then be toast (but in all fairness it probably already is). If you can't format it then you need to google for memory card data rescue utilities. If none of these suggestions pan out, I would start the warranty procedures with the manufacturer to get it replaced.
Hope this helps!
EDIT: Nevermind. I'm new to OSX and didn't realize that when I delete a file on the sd card it doesn't actually delete the file until I empty trash on mac.
I bought a 16GB Class 6 Adata micro sdhc card from Newegg several months ago. I never thought there was any issue with the card as it showed up as 16GB on my PC and in phone settings.
Yesterday the sd card memory was full which seemed weird since I knew I didn't have that much data on there. On my PC it said the sd card was 15.9GB full out of 16GB. I roughly added up the size of all the files on the SD card and it came out to slightly under 4GB. It appears my 16GB sd card is really a 4GB sd card.
Has anyone else had this experience with the Adata 16GB card from Newegg? I know it was a fairly popular buy.
This may just be a case of me being genuinely unlucky in my purchases but humour me anyway!
Like you lot I have an SGS and with all the recent mods regarding sound I like to use it as my mp3 player, so buying a micro sd card for additional storage was a must.
I had a spare 4gb class 2 card lying around so I've been using that for some months. Finally decided to upgrade to a more meaningful 16gb class 4 card.
Ordered one off Amazon through a seller. As soon as I put the card in the phone, it refused to recognise it but my PC, digital camera, old blackberry 9000 and n95 saw it just fine. So I formatted the card in the pc using the downloadable SD Card formatter as some googling suggested this might return the card to a working state. After that the phone saw a 16gb card, so I copied some music onto it, it worked for about 30 mins and then the card died totally. Upon reinserting it into the pc, windows only saw an 8mb card in RAW format and nothing I've done since has recovered the card. Card was dead.
Anyway I contacted the seller who posted me a nice shiny Kingson 16gb class 6 card right away.
New card arrived last night, appeared in the phone straight away as a 16gb card. Great start.
Plugged the phone in, started copying some music on it - the write speed was incredibly slow. I mean really slow, 100mb of mp3s was taking the best part of 3 minutes. Popped the card in the PC, same problem.
I find that I can actually write data to the card till its full (albeit slowly) but once you've written more than around 4gb of data, the files start to vanish.
I know it sounds incredibly stupid but anything written after around the 4gb mark just doesn't appear when I plug it into the phone or the PC. The card claims it is full, but only 4gb of data is visible, let alone accessible. I've done the usual formatting of the card and changing card readers etc etc but the result is the same and this is starting to grow boring.
So, question. Am I just incredibly unlucky in my purchases or is my SGS killing cards? Because I'm quite weary of buying yet another card now.
Funny enough my old 4gb card still works just fine like it has for years.
I know you'll have a FAT (file allocation table) that usually reserves a predetermined amount of space on the card for file locations. But your memory card should not be able to accept more than whats available and should be displayed correctly no matter what your using. IE pc or phone. Kingston are fairly reputable, but is your dealer reputable. There are a lot of counterfeits out there. I don't believe the phone itself is damaging these cards. Since your stating your old trusty card still works like a champ

Ok So I picked up a sandisk 64GB pixor external sd card, I was able to transfer files to it fine by connecting to a windows machine, sometimes. Apps like wifi transfer and airdroid failed every time to upload files to external sd card, but transferred fine to internal storage. I managed to get some music on the card, and after playing one song, the rest gave me errors.
Ok, corrupted SD card, no big deal. returned it a got another one. Sandisk "Ultra Plus" 64GB, I have yet to try a hard wire transfer on a windows machine, but so far wifi transferring is still failing. I'm beginning to think it may be a phone issue instead of a card issue.
Has anyone else had problems using wifi transfer to external SD card? Any advice would be appreciated!!
Its a KitKat issue. Some devices have fixes and patches. Might find one if you do enough digging.

I had the same issue. Download NextApp SDFix from the Play store. It makes all your access issues go away.
I would link you but this is my first post and I'm not allowed to.
Greetings!
I purchased a new SD card from SanDisk with 400GB.(didn't use my old one on this phone because of low storage size)
My problem is that i'm unable to copy/move/delete files to my SD card.
I can't even create a new folder.
I tried several explorers and activated the permissions for writing but no success.
I was also trying another SD card but the same problem.
If I format the card over my phone as internal storage the phone freezes, formatting as external storage is working though.
I also formatted the card on my PC but still the same issue.
Remounting the card in the settings sometimes works for a few seconds.(creating a folder,etc..)
My razer phone 2 has the newest FW with Android 9.

Heya buddy,
Just a quick enquiry, from where did you purchase your MICROSD? it sounds like you may have a fake card, the memory size is worrying indication, normally cards are sold in denominations of 32, 64, 128, 512,GB not 400 GB. Have you run a check to see if it's reporting the correct capacity size on a SD card checker. Sounds like it's a fake and when it tries to format, it goes into a loop state and crashes as the card is formatted over and over and over trying to reach the stated size but never reaches it due to it not being 400gb in size.
Sorry to spread the bad news, have had the same happen to me, I am so dam careful over which company I buy my cards from.
Let me know if I can help.
Yours

Phone says it has 393GB.
I bought it on amazon. Its a SanDisk Ultra 400GB that also appears on the official homepage. I'm pretty sure its not a fake.

Ok, that clears up the possibility of it being fake good good..
..hmmmmm. Do you have any old phones at your disposal that have a card slot? If so,. Try it in those and see if you can access it and read/write/modify files on it. Maybe format it with another device and then stick it in the razer and see if it works.
I'm sure now that cards a real deal as Amazon don't seem to allow frauds to be sold the only other thing I can think of is that it's a faulty card, it happens, they are just mass produced. Maybe a replacement if it's dudd.
I am having an SD card issue as well. I have had my Razer Phone 2 since last Monday brand new from Ebay. I purchased a Samsung 128GB class 10 (u3) SD card for it from Amazon. If I format the SD card as "internal", it shows that there is 131GB's of system files on my SD card. It shows I'm using 131GB's of storage from a total of 320GB's. The Razer Phone 2 has 64GB;s plus my 128GB SD card which would be 192GB;s total. I have tried many file manager apps, move to SD apps, etc and I cannot transfer any files. When I format the 128GB SD card as "portable", it shows the correct amount of storage space in both the phone and the card but once again I cannot transfer any files to the card. I have tried a 16GB SD card as well. The phone did recognize it and read the available storage on the phone and the card correctly. I did not format that card as I have music, photos and documents on it. I did try to transfer an app from my phone to the 16GB card and once again I could not do that. Any help would be appreciated. Thank you in advance and take care.
I have had similar problems with my Razer2. It ruined a 512g scandisk brand microsd card. Copying, or moving files, is a real problem for this device! It hangs up sometimes and ruins the files. Never had these issues, this bad, with any other phone
I have a bunch of music on my SD card, my music app sees some of them. If I move the whole folder to my phone storage, music app sees all. If I boot to twrp (per arters kernel) and try to backup to external SD card, it fails. If I save it to the phone, works fine. It's like it doesn't constantly see the SD card slot properly.
Exfat is needed with art kernel. Stock formats as vfat a old file system. I have a 400gb exfat formatted and works perfectly
I'll have to look into getting that kernal
