I experiencing a very annoying problem with my external SD card.
It seems I am not the only one: http://talk.sonymobile.com/t5/Xperia-Z1-Z1s/Z1-destroy-files-on-SD-card/td-p/418011
Basically I loose random data when I store them on external SD card.
Many random data: let's say about 30-40% of what I stored.
This happens:
* if I copy data from internal memory to external direcly with the phone
* if I copy data from the PC to external card using USB connection while the card is in the phone
* even if I copy data onto the card and THEN insert it into the phone
The SD card is a brand new Samsung Class 10 64GB and I tried also with an old 32GB Sandisk with the same result.
I formatted the card either exFAT or FAT32 and in both cases I can fill it without loosing a single byte with the PC.
I am on .157 stock firmware (only rooted to use Titanium Backup and a few tools) but I had the same problem with .133.
Any possible solution in your expert opionions? It is really frustrating to have only 11GB storage in such a great phone!!!
Got three guesses
It does not correctly unmount the card when connecting the phone to the PC in Mass Storage mode
Kernel Bug. On exFat I would expect that, not on fat32. Can be ruled out if it does not happen with custom roms
Voltage on the SD Card suddently drops for some hardware design reason. Should happen on all ROM's
Sounds like some testing is needed? For example #2 is easy to test when someone with the problem flashes a custom rom with and tests the same sd card again.

Help,
After i flashed my KAISER i have a problem. The sd card is not recognised anymore. Is there a solution for this problem?
I hope so, otherwise i have a brick
Storage card problem
I always used a 4 gig card, just tried an 512 mb card, and that one was recognised. Strange isn't it?
First, which method did you use to flash your new ROM?
If you used the USB method to flash your new ROM, did you remove your SD card during the flash process?
If you used the SD card method to flash your new ROM, did you do a hard reset with your SD card inserted?
Second, do you have an SD card reader for your computer? I would probably try to verify that the file system and data are intact on your SD card. If you have an SD card reader, you can also use it to reformat your card.
If none of this is helpful, provide some more information to fill in the gap between your microSD card working properly and not showing up on your phone.
Re
I flashed to TPCV5.1 full today. No sd in my phone.
My cars reader in the computer doesn't recognise the sd card either.
Strange thing is , when i use an other 4 gig sd card, the phone still doesn't recognise it, my card reader on my computer does, so why not on my phone.
I had a 2 gig sd card, and put all the data again on it, and it's working.
Stilli have a problem that my phone won't recognise a 4 gig sd card.
So far my story.
Does seem odd. What file system is your 4GB card formatted with? If it shows up as "RAW" or anything, I would definately format it to FAT32.
Edit: I was referring to your "other" 4GB card. I don't think I have any advice for the original one.
i hav htc t-mobile wing
i have inserted micro sd card in the sd card slot of it
but in the storage card memory it says "total storage card memory : not installed"
i have also tried other cards (witch acually ran in other phones and also on pc) but they does not work with my htc
PROBLEM HISTORY: previosly my phone was working all right. even with 2gb micro sd card.
on that day i have oped file explorer<storage card
i slided the phone it stoped showin up storage card
some time later it automatically showed the card
but again later it disapeared
(b4f that i also used to pull out my sd card regularly for data transfer)
the i stopped doing it and for aroud 10 5 to 6 days it worked properly and then this p[roblem came up
SOLUTIONS I TRIED:
1,SOFT FORMATD
2,HARD FORMATED
3,ROM UPGRADE (rom downloaded from this site)
so any solution u people got ............................
Did you try to read the SD card in another place (ie PC) ?
Maybe you must format the card using any of the apps to format or data-recover. This happens sometimes with the cards, so that you must backup them in your computer and reformat them, or the phone will crash.
(That's what is happening me now... and I missed soem data)
no this dose not work
Some info:
LG optimus 2x
MIUI rom
16GB SD card
Fat 32 format
only 392mb used
PC recognises full 16gb (well, 14ish due to formatting) and phone sees 5.50GB. It also says that its only got 40-50mb space remaining which is completely wrong.
I've formatted the SD card through the phone & PC (using the slower format too)
The SD card was used as a recovery SD for my Nook Colour before the current phone and I'm not sure whats wrong.
Any suggestions?
Just to make sure:
Check that you're not looking at the internal sd (since that one is 5.5 GB)
Hmm, how embarrassing. I think I am looking at the internal SD card.
However under the SD card menu, I can unmount/mount the (5.5gb) internal memory and format it (which I've already formatted )
Any thoughts on how to view the external SD card? there doesnt seem to be a menu for it in the MIUI settings
I would look in /mnt/emmc, sound likes the mount points have been switched.
I have the above memory card for my N7000 (Rocket Rom v3) and am having problems verifying its capacity.
H2testw (Windows utility) verified it as having no errors and as 32Gb
ES File Explorer's SD card analyst displays capacity as 11.06Gb
SD Tools displays capacity as 11.6Gb
I have tried copying music (21Gb) to the sdcard using two methods. Firstly connecting the phone as a media device which was very slow and started to throw up errors after a while. Then secondly by removing the SD card from the phone and plugging it into my laptop (Win7) which was far quicker. This second method didn't throw up any errors BUT when I put the card back into my phone no files were found!
I am beginning to think I have a fake SD card which when plugged straight into my laptop is telling it 'Yes I'm a 32GB card' but for some strange reason allows it to copy too many files to the card without complaint. I am going to do some tests to check this out.
In the meantime is there an alternative utility which is guaranteed to verify what my card is either on Android or MS?
Thanks
Please try to do a SD card format on your laptop before putting it in your phone
It might be an issue with its storage that is preventing android from detecting the full size
If that didn't work, try to format the memory card over the phone (using settings)
Best of luck

Okay there were 2 problems, the first one was getting the memory card to be read by my note which I've now managed to do, not sure what I did but there you go, but it certainly wasn't reading before.
The second problem and this is a little embarrassing but when ES File Explorer opens up it displays the contents of the "/sdcard/" by default which on my old desire was the external sdcard but on my note its the internal memory! Not the external sdcard! To view the external sdcard you need to navigate to "/storage/extSdCard/" which is downright misleading unless you come from a Unix mindset of course
SDTools just seems incapable of picking up the external SD card and can only see the internal memory.
Solved
Hi all,
I have a sandisk SD card in my phone set as internal storage since I got it.
Today it is going funny...I can see it in the list of storage but when I browse it I don't see any contents.
I plugged the phone into PC and it shows as 22.8gb free of 119gb but also will not show any contents.
I have removed and reinserted the SD card, I have tried setting it as internal storage again but no luck.
Even in ES File Manager I see the SD card name but once selected no content.
Currently cannot try the SD card in computer directly as I am in office and don't have an Micro to standard SD adaptor card with me. I am not too concerned about data loss as all my photos are backed up on Onedrive and my music on my laptop.
Did anyone else have issues such as this in the past?
Any tips on how to resolve without having to format SD card and copy everything back?
Cheers
Ok, very strange.
In my laptop using card directly everything is there with no issues but phone just sees the 22gb empty part of SD card.
I tried another blank Samsung SD card and it works fine so I copied the data from the card with the issue and everything works fine.
Formatted the card playing up and also is fine.
So no idea why the phone decided not to see all the data on the SD card that was in it for last 6 months.
