I also had a Kingston 32GB card go non responsive in my Xperia Z, luckily I had done a backup about a week earlier - My reply from Kingston was that there has been problem's with some SD card's, not just their SD card's but other manufacturer's too and it's not just the SONY phone's/Tablet's that are affected, a quick browse round the net and i found load's of other mobile brand's were having the same problem - Samsung being the most talked about (probably as so many people have Galaxy's). So, the problem is between the SD card and the OS not the phone's/Tablet's themselve's ! Kingston sent me out a new 32GB card very quickly - Thank's :-) and my Xperia Z was back to normal once my backup was re-installed :-) Xperia Z & Tablet Z are fantastic pieces of kit.

Not sure if this is the right place, since I have a ZL and a Z2.
The ZL has over the last 6 months (from new, back in Jan) burned up three micro SD cards:
- Lexar 16GB, class 10
- No Name 2GB, class 6
- Kingston 32GB, Class 10
All have the same issues:
- work fine for a period of time
- no warning, and then get something like:
"SD Card not mounted", "Error Transferring to SD card", "Transfer interupted. Check SD for files"
The card will no longer work. Tried loading into SD Card carier on my PC - not recognized. Can't format it, etc.
So far, the ZL (3 months old) is okay. BUT, I'm backing up the SD card contents every 2 days since I'm pretty sure it's going to get killed as well.
The forumns say it's an issue with Android 4.4.2 writing to the SD card 100's, if not 1000's of times a day.

I think the problem relies in the android version. I have the same problem than you, but it all started when I upgraded from android 4.2.2 to 4.4.4. The only software that seems to work fine is the file commander from xperia. My other devices can read and write to the microsd cards.

I've been using a 64 GB Samsung micro SDXC on my Xperia Z1 for a while. It used to work fine but today my phone started behaving oddly (it turned off and rebooted all on its own, and it didn't ask for password number afterwards...) and some hours later it started launching a message saying the sd card was removed. This message appears for less than a second and disappears, being replaced instantly by another message saying that an sd card is now conected. This message also disappears really fast, and it goes on and on like this, in a cycle.
I can't access the card through my phone and when I try to format it with my pc it says it's locked (when it certainly wasn't prior to this problem), although I can access its content. I used windows diskpart to clear the readonly problem, but it didn't work, so I think the phone probably damaged the micro SDXC card in an unusual way. I know for a fact that the card fits perfectly, it isn't loose, it isn't dusty or scratched or wer or inserted backwards.... I've tried every obvious solution for the problem and many not-so-ovious too. This wasn't an inexpesive card by my standards and I can't afford to be ruining SDXC cards on a regular basis so a solution for this problem would be greatly appreciated.
