Two days ago and while I was synchronicing the phone it had a crash and all of the files on the micro SD card were deleted or at least that was what I thought, I reinstalled the apps....no problem there, but to my surprise I loosed around one giga or maybe more of space on the SD according to the phone.
I have explored for files and the sum of my real files is not bigger than 2G, but the phone keeps saying there's only 200 mb remaining of space remaining on the card. Is a format the only way to go? Any advice? Thanks !
Copy all the files from the card to your PC with a reader, format, copy the files back. You can try a scandisk before, but I wouldn't even bother.
I have AT&T Tilt with Sakajati's HyperDragon IV Windows Mobile 6.1 OS ROM, I also have this 8 GB micro SD card, which has around 3.5 GB of data, but for some reason I am not able to write on it any more. When ever I tried to format it I get this message which says " The card is write protected" I don't remember putting any password or anything. I can read data from that card on any computer or phone, but can write anymore data on the card. I can't delete anything from the card either.
Can someone suggest what could be wrong with the card and how can I unlock it?
I have tried low level format also, the format completes without any error, but when see in file explorer all the files are still there. If I try to format from SD formatter, I get error "The memory card is write protected", windows format doesn't give any error, just runs and in the end says "Windows can't comeplte the format". Card is working file and have no problem in reading the data it has, just can't write new one ot delete old one.
This is very weird problem... any help/comment is good.
Not sure if this will help....
I've had very similar issues over time...
Because of high TomTom & Music Use.
Both are loaded and work off my SD Card (6 GB worth)
What I finally found that worked for me, was to get a 2nd card and backing up my SD card to my Desktop PC, so later I could transfer to the 2nd SD Card when needed.
Then I do a Complete Format [Full FAT32 Format] of the old SD Card, via the Mini SD adapter on my Desktop PC.
I found that formating within the phone doesn't always work...
If this is not the case I can think of 2 other reasons for potential problems..
~Some ROM's require the removal of SIM & SD Cards when installing?
~If you were using an adapter formating the SD Card and it was not set to write mode?
Best of Luck!
JAC,
Thanks for your reply, but I have already tried FAT32 formatting using micro sd card, but as I said before, but it errored out.I even tried low level format, but didn't work. There is no locking swithc or anythign in micro SD card, not sure how the data can be locked. If it was ecrypted I was not able to read data on other devices. So what happened? Any help!!!
Like everything else, sometimes things just wear out, break or are just low quality to begin with. If you can read it on other devices, then transfer it and get a new card.
There is also a trick used by nefarious suppliers that takes a 4GB (or any size chip) and format it in a way that it appears as a larger chip. Then when you go to write to it the whole thing goes crazy.
This is why I recommend using reputable resellers and buying good quality Name Brand Chips, Like Sandisk or Kingston.
Hey guys,
Im new to the forum but ive been following quietly for a while. I thought id make my first post, a new thread because ive been having an issue which i dont know is common or not but has been killing me for the past 4 days and i havent been able to find a solution.
BASICALLY,
My MicroSD 64GB (Master UHS-1 Class 10) has all of a sudden decided not to work on me and here is the problem.
First let me establish a few things.
-> MicroSD reads on any computer (im running mac)
-> MicroSD was formatted on my Xperia Z and has been working for the last 3 weeks
-> I have ejected the MicroSD several times without properly unmounting it from the phone (being honest)
-> Files can be read and copied onto the computer
-> Files can be copied onto the MicroSD but once ejected from the computer and reinserted, the files disappear. Its as if the files that are existing on the MicroSD are locked there forever.
-> Files can be deleted and do appear to have been deleted, however once the MicroSD is reinserted into the computer, (Via usb or SD reader), the files just appear again.
Problems:
-> I am trying to format the MicroSD using Disk Utlilty on Mac but to no avail. i have tried every single option and i have even used SD formatter 3.1 which is a third party program. On mac, all i get is an error saying "Mac OSX was unable to repair the disk" -"you can still open or copy files on the disk, but you cant save changes to files on the disk. Back up the disk and reformat as soon as you can."
-> windows gives me the same error. in windows format. I can do exactly the same i.e copy and paste files onto the MicroSD which disappear, i can delete files which reappear and when i attempt to format using even MS-DOS's "DiskPart" utility, which is supposed to be epic, it still does not work..
I just want to reformat the disk and kill everything on it and return it back to normal.
Ive looked at so many searches and read so many web pages, forums, blogs, everything but i could not find a solid solution. Nothing Works.
MY FINAL PROBLEM!!
Once the Micro SD is placed into the Xperia Z, a message pops up saying "preparing micro SD card.. Checking Errors" This message DOES NOT disappear for hours. ive had it on for half a day and it drained my battery to 26% before i realised that it was killing my battery. it was on standby aswell. I have an old 2GB microsd which i used and the message pops up for about 1 second before it disappears.
This is my problem. I cant use the MicroSD on my Xperia Z anymore. The phone just wont read it. It will prepare it for the next century.
If anyone has any suggestions to how i can get these haunted files off my MicroSD and get it back in working order id really appreciate your help!!
Thanks!!
FAT32, NTFS or exFAT?
Running stock or rooted?
I'm running third party software (paragon), and using NTFS.
17gb bluray movie worked without stuttering, and overall seems stable.
I'm rooted.
Thanks benziii for your reply!
My Xperia Z is rooted and with unlocked bootloader. I think it may have something to do with corrupted files? because of removing the MicroSD without unmounting it all the time perhaps? or i really dont know.
By the way its formatted as MS-DOS (FAT) at the moment =/ cant seem to do anything still. or change it.
Tired formatting in different format with no luck
& im trying to get access to a windows computer atm because i find there are many more third party apps on windows than there is on mac.
My Xperia Z is unlocked and rooted and I am using Sandisk 64gb class 10 sd card and no problems. But its just me! :laugh:
If I were to guess I'd say that the card has been corrupted. It may work with a low level format, or it may not.

1. Removing the card without unmounting it is seriously asking for problems.
2. My Xperia Z documentation says it supports up to 32gb cards. i.e. not 64gb.

Perhaps, but it's doubtful they can do anything you can't do on your Mac or Linux.
On OS X, you can run the following two items from the terminal as root:
1. fdisk
2. newfs ((I assume you want "dos" or "exfat" file system types).
Just, you know, make sure you get the drive right and don't nuke your Mac's hard drive by accident!
I thought max size was 32gb also

Officially it is, but I've seen 64gb cards referenced as working many times. I think it's just a matter of the phone not working to SDXC specifications. Though that's hardly a good reason, as everything else on the phone is first class...
Everyday is a learning day.

It seems your SD card is dead My SXZ broke one SD card (32GB Transcend Ultimate, 10 class) in the first week of using - now it is recognized as 1 GB unknown disk with RAW filesystem. So I had to buy new one (32 GB Sandisk Ultra, 10 class).
My phone just loses SD sometimes and doesn't recognize it till restart. Before installing .434 firmware update I met this problem very often. Now (after installing .434) I meet it sometimes when open stock Camera app. I think that is firmware bug, so waiting for next updates.

I was doing some research and realised that before a MicroSD card dies, it will write protect the data before the MSD card dies so that you can back up any data. you can delete files and copy files but they will autodelete themselves after the card is remounted. thats exactly the problem that i have.. oh well thanks guys. i sent the card back for replacement!! hopefully next one i wont screw over too.
Lesson learnt. never eject sd card without unmounting on phone first!! thanks guys!

Interesting.
I bought a 32GB Transcend class10 MicroSD card from Amazon at the same time as I ordered my Xperia Z.
I did manage to copy around 10Gb of music to it, using Sony Bridge For Mac before it was suddenly 'disconnected' part way through the copy process (I was filling it to 25Gb with music from an iTunes Playlist).
After that I tried it in the Mac directly and a Windows laptop, neither of which would write to the MicroSD card, some of the files could be read, but not many. While SDFormatter claimed to have formatted the card, the files (or their names at least) were still visible, further attempts at formatting the card (with SDFormatter) claimed it was write protected.
Putting it directly into the Xperia Z would cause it to reboot after 2-3 minutes.
I returned the card to Amazon. If it had worked on my Mac (or laptop) I might have kept it, but working on nothing made it useless.
I am currently using an old 8Gb MicroSD card that came with (I think...) the Sony Arc I had a few years back and it seems to work perfectly. I'm loath to buy another 32Gb card to find that it doesn't work.
I assume there is no reason why the Xperia Z shouldn't work with a 32Gb MicroSD card? Do I need to ensure that I get a different class of card, or is a class 10 card suitable? Is it just not compatible with the Transcend card?
Any suggestions you have will be most helpful.

same thing happens to me! files remove and reappear ! "chkdsk /f command" in windows shows that one of my files is cross-linked! here is the message:
\App\install\.goutputstream-5JN7ZW is cross-linked on allocation unit 1181239.
i i tried formatting with windows paragon linux (fdisk,mkfs.msdos,gparted,testdisk...)even i ran windows 98 and ran scandisk for fixing cross-link issue ! but till now no luck.
can anyone help me with this
thanks in advance!
in my opinion there is no way to repair this, just throw it in trashbin.. ive tryd almost all..
I'm in the middle of an RMA with SanDisk right now. It seems that once the sd decides to be read only to protect itself, it's done. Replacement is the only option.

i have the same problem with my 32gb sandisk sdcard,Tried almost everything and nothing worked.
Hi guys, I have a 64GB SanDisk Ultra MicroSD class 10 card. I use it on my Samsung Galaxy s3. Couple of days ago I went to my friend and ask him to give me some movies. He was sending it via data cable but we got frustrated and we had to go somewhere so in the middle of transferring data he unplugged the cable and now my SDcard isn't working anymore. I mean can it be damaged just because we unplugged it in the middle of transferring? I've done it so many times before but it wasn't really a problem. Anyway I'll try to explain what I did with my card since then and what was it's response.
1. The data in the card is intact, I've backed it up as well and when I put my card into my phone it works perfectly. (btw the card was in FAT32 format)
2. I can copy stuff into my card but when I put into my phone it wouldn't show and when I put it back on card reader again the file disappears.
3. I can delete stuff from my card then I take it out and put it back again and the file that I've just deleted comes back.
4. I've tried formatting it but it would give me an error.
5. I've used Easeus partition manager but it would give me an error as well.
6. Then I've used the software I've used when I first formatted the card to FAT32. Guiformat. It would format my card normally but when I go into my card all the files are there.
7. I've tried using commands like "chkdsk d:/r or chkdsk d:/f etc but after like 44% it would say certain files are invalid and can't continue the do the checkdisk command (the file it shows was the files I tried to get from my friend)
8. I've tried so many other stuffs but none of them seems to able to format my card.
now my question to you guys is my card really dead? can it be dead just for interrupting file transfer? is there any way to get my card back to normal? anyway I can format my card? I'd really appreciate it if any of you guys can help. Thanks
Help!
1) I cannot save correctly any file on my external 128GB SD memory card. PDF files are saved in a corrupted format. If I create with Total Commander a new folder, it gets deleted later on.
2) The tablet is not rooted.
3) I even tried to copy files via Windows to the tablet via USB-cable and I receive the same error.
Is there a way to check the SD card for errors through Android?
Thank you!
Agreed, doesn't matter which SD card I use.
I have the same issue, I've tried both a cheap, ebay purchased SD card and Samsung SD card from a store. I have the SM-T813. Both of the SD cards had exactly the same issue. I've not rooted the tablet yet, though this is a key reason I'd like to try rooting the tablet.
If this were my problem, I'd pop the card, put in in a USB reader, and try it out directly under Windows. It may need to be reformatted or even re-partitioned.
I contacted the manufacturer. I'll get a replacement because it's broken physically.
