That's interesting about the Trancend Class 10 I've just bought an 8gb one to use with
a Samsung GX-20 and yesterday when I put the card in having already used it about
3 times, the Camera flashed up CARD ERROR. I switched off and took the card out, put
it back in again then the camera on and this time it worked OK. I took about 10 photos
and looked at them on a XP Desktop and they were fine.
I looked at some from the day before on the same card but in the previous days
directory some of them showed up OK others just showed a Black picture. I tried
copying them to the HD but Explorer couldn't do it. I tried deleting one of them and it
couldn't do that either so I tried Scandisk on the card and it didn't find any errors
although it did say it would need to re-boot to fix any it found, which I thought was
ridiculous, Windows 98 could fix stuff on a removable drive without a re-boot.
Obviously something wrong so I took the card to a Windows 7 Desktop and ran
Scandisk on the card and it found truncated files in the Dir I had problems with.
I let it fix them but the images were messed up so I deleted the dir. Only about
12 unimportant images were lost.
This morning when I booted the XP machine up, Scandisk stopped it from starting until I did a scan. It seemed to fix it but I'm concerned that some files may be damaged.
I've never had any problems at all with my usual cards, Toshiba White in 4 and 8GB.
The Toshiba White's even though Class 6 are also faster.

Very slow Random Write speed 512KB : 0.946 MB/s with the Transcend although
I doubt if we ever actually use that with photos.
I'm very concerned that not only the camera noticed a problem, but also that
the previous days files were trashed. I'd return the card except I threw away
the receipt and packaging.
