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 all,
Was just wondering if anyone had encountered this issue. I'm on latest stock firmware (V20b), and I recently bought a 32gb Samsung SD card to upgrade from the 16gb Lexar card I had been using.
The card is from a reputable seller and works fine in my laptop and old Android phones. It also checks out fine with h2testw 1.4.
However, it does NOT work in my 4X HD. In the 'Storage' menu it recognises the capacity, but attempting to transfer anything via the USB cable results in failure. Formatting the card in the phone appears to work, but causes popups like 'Unfortunately, Google+ has stopped'.
Opening any app which uses the SD card (camera, music, etc) results in that application crashing immediately.
I tried putting in an old 2GB Samsung card, and got the same results.
Is anyone using Samsung SD cards with success in this phone? Don't want to factory reset if it's unlikely to fix it.
64 gig Samsung card works fine in mine, however I only used it for about 10 minutes while stock, just long enough to unlock it and flash carbonrom xD
I've been always using a 16 gb Samsung sdcard

Hmm, thanks for that. Might have to do a factory reset or something.

I'm using 16GB Samsung sd card too.
Ok, just a follow up. Did a factory reset and it works fine now, so I can't fathom what was wrong before.
Thanks everyone for letting me know my efforts wouldn't be in vain.
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
I had my Samsung Galaxy Mini for over a year now and had absolutely no problems what so ever even after rooting it.
Week ago every application I try to install gives the "usb memory not mounted" error, so after searching and trying to solve this problem as it is an internal memory space issue couldn't solve and gave up eventually.
Days after I tried to install another application and it did install successfully, but then I restarted the phone and it was gone along with all pictures I captured at this duration were all gone, so I thought it was a SD card issue and started on trying to figure what was that.
I tried to add, remove files via the PC but after mounting the SD card to the device like there's lock and nothing happened. Tried to format the SD card using the device settings and the PC but still after reconnecting the SD card nothing changed.
Thought perhaps the SD card is broken, so I bought a new one which worked fine before mounting it to the device tried to take a picture and there it was, then I unmounted the SD card and mounted it once more in to the mobile and the picture was gone and the same story happened again. I even tried with another 3 brand new SD card, same story happened.
Please if you know what is that and if there any way to unlock the card tell me what to do.
PS. The microSD adapter isn't locked. And I'm not an android professional I'm a newbie XD
Hi
This is my first time posting so apologies in advance if something similar to this has been asked.
I have recently purchased a Kingston Micro SD Card 16GB for use with my Moto G.
After formatting it, once on my pc and also once on the phone itself, I decided to try and move some of my apps from phone to SD, which when I did, would not respond or even boot up the app. I also tried moving data to the card, to no avail as none of the audio files would be opened. I own the newest updated KitKat version as I have not yet been given the option to update to Lollipop.
Am I doing something wrong? Would the issue be in a faulty Micro SD card or would it be possible that this is some issue with the phone itself?
Thanks
Reformat card using phone and try again.
