A problem with my SD card

Hi guys.
I've got an original 16gb Lexar, Class 10, bought on Amazon. My software is Gingerbread 2.3.3.
A few days ago I got a "Blank SD Card" error. The only solution seemed to be the format of the card. I have put the card into a card reader in my computer to try and get the data back, but all I managed to recover was some pictures from my holiday (I used a program for that). The card was in RAW state. I couldn't format it with my phone (nothing happened when I did) so I formatted it using my computer. I also did a factory reset to start from a scratch.
The same error appeared today morning. I did the same thing, but I insalled only trusted and well known apps such as Go Locker, Zedge and Fancy widgets. Everything was fine up to now - I didn't get an error this time, but everything on my card has been deleted (only the system folders such as DCIM and Android are on it, but there's nothing inside of them). All the application installed on my card are unavailable.
I'll be grateful for any help, I have no idea what to do. :crying:
Thanks,
Draggy
Edit: It's a Micro SDHC card of course, sorry for the mistake.

Are you sure it's a legit card?
Check if there is holographic stickers or anything that mark the product genuine.

Master 64 GB MicroSD SDXC unable to format/delete files

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.

[Q] S3 LTE Problem with 64GB External SD Card

Hallo everybody ,
i bought a 64 GB SD Card for my S3 LTE, Im currently on PAC Rom´s nightly (JB 4.4.2) and everything works fine.
My 16 GB Sd works without any Problems, also did my 8 GB one´s
If i insert my 64 Card it´s also working ok, i can copy paste anything to it and use the moved data.
BUT.
Here´s the point.
If i Restart the Phone or remount the Card it shows up "preparing sd card" and nothing happens.
i thought it may take a little bit longer but 2 day´s should be more than enought
Tried it several times, only way to use it again is to format it.
So if there is data on it, it doesn´t work, empty everything is fine.
Any suggestions ?
May be a littlebit crashy english but im from germany and in a Hurry right now hope you understand everything

Ok, first: Are you sure it's a 64 gb one ? Test it.
Second, how and where are you formating it ?

Had the same problem with my 32GB* micro SD card on my S3 I9305 LTE, it kept saying preparing SD card, it was constantly mounting and unmounting. It was due to the fact the the 32GB card was a Chinese counterfeit. It says 32GB on both the card and in settings>storage, but when tested using H2W, it was only 4GB. I bought an original Samsung 64GB Micro SD and the problem was resolved. Almost all the cheap memory card found on eBay are counterfeit. Buy your card at an official distributor of the brand. don't be tempted by the cheap ones on eBay.

It's a 64 gb card, I formatted it with paragon and it worked, it also said 64gb, I formatted it into exfat, ntfs, fat, and fat32 neither worked :/
Any solutions?

Try on a computer if you can actually store 64GB of data on the card, and then read it back successfully. H2testw is the best way to do this.

Same here with different ROMs and a Sandisk 64GB (real ) -...
Tested all kind of ROMs and kernels to no avail
Gave up and live with 32GB since ....

[Q] XT1068 keeps rebooting if extSD is on

Hello everyone, I would like to ask for your help.
About 1,5 month ago I acquired my XT1068 at the time it was on android 4.4.4. I installed my 16gb SDcard (SanDisk, class 4) and everything looks going well.
After one week I started experiencing some issues, sudden warnings "SD card has been removed suddenly". After that error, my SD is no longer recognized, unless I put it on the computer and format it (FAT32). Over the time, the problem is becoming more common.
Motorola released the official update to 5.0.2, and after the update the problem persisted. At this time I've already rooted my phone and using TWRP in recovery.
So I though it really was the SD card. I bought a new one, a Kingston 8gb class 10, and now the cellphone instead of simply dismount the SD, it keeps rebooting every time I turn off the screen. Here's a little list of thing I've already tried (all doesn't have affected the problem):
-Change the ROM:
Downgrade to 4.4.4 Stock
The Titan Prime ROM
MicroKAT v1.0
Shohat
-SD cards
16gb Sandisk class 4 (keeps unmounting)
4gb SanDisk class 4 (keeps unmounting)
8gb Kingston Class 10 (keeps rebooting on standby)
- Apps
SD booster
Link 2 SD
So, I don't have any ideas left, I goggled e visited forum of all kinds, doesn't found anything like my problem. This can be a hardware problem? Permissions?
I've thinking, there is a way to trick the system and change the internal storage/system partitions to the external SD? Maybe this solve the problem, i don't know...
Sorry my english, and thank you in advance.
Greetings!

I don't really know. I had this problem on my previous phone (SGS+, the unmounting problem). I solved it by buying an new sd-card... But since you have multiple sd-cards with the same problem? Occuring on KitKat aswell as Lollipop? Or your cardholder has a defect or you're buying very cheap sd-cards!
Bye the way, Link2SD is a great app for providing more space, but known to be a SD-Card killer due to the very frequent writes and deletes on the SD-card while opening and closing apps.

SD-Booster? Probably is the guilty one...
Try without SD-Booster...

Thanks for your response Poeta.
Already did. In all ROM installations, the problem was present even before I install any app.

With a clean MicroSD? Or the old one, without formatted the SD?

I only installed SD booster one time, and as soon I realized it don't solve the problem, I uninstalled it. Yes, every time I inserted the SD card, I've formatted it on the computer previously.

My SD Card keeps dissapearing. Help!

Hello there. My moto is thea, the 2nd gen with LTE, but this forum is way more active so I write here instead. Overall the phone is great, running Lineage OS 14.1 smooth as butter. One problem keeps bothering me though: my 64GB SanDisk Ultra Class 10 XC I SD Card keeps dissapearing out of nowhere. No ejection notification, nothing. Rebooting the device doesnt help aswell, except for some strange cases when it reappears back out of nowhere. Only reinserting the sd card works until its gone again.
It's not because of the rom - happened on stock aswell. I tried the card on another phone, works without a problem.
Browsing pictures on my sd from the gallery seems to cause this problem aswell, but somehow browsing them from the file manager doesnt.
I dont have another sd card to test if its the phone, but somewhere ive read the Moto G2 has a problem with this excact SanDisk card.
Any help would be appreciated. Thanks.

Clean Flash Another ROM Or Flash STOCK And Insert SD After Formatting.
Try To Format SD Card By "DISKPART" Command On Windows (Search It On Google How To Use Diskpart To Format SD If You Don't Know).
