Sure, I received it 2 days ago in the mail, opened it, plugged it in, and transferred all my games/music/skins etc. About halfway through the transfer, it stopped, asking me to re insert the disk into the drive, and when I tried again, it came up in my explorer as 'Removable Disk' with an unknown format, 0kbs of space.
Turns out I was using a regular SD reader, not SDHC, by SanDisk. May I ask what program you used, so I don't have to buy a new one if I don't have to? Also do you think the fact I used a regular one first might have contributed to this?

Thats what worked for me. I have 2 AData 4gb cards. I had problems with the Cyclo evo card reader and both versions of the R4 readers. The readers would disconnect randomly, not recognize cards, and freeze during transfers. I have been using a rosewill and a sandisk adapter recently without problem.
Oh the cyclods reader has problems with SDHC? Oh my. I'll keep that in mind when getting an SDHC in the future, but one thing I'd like to know about these, are there any speed issues, on let's say Class 6 cards, on the cyclo.
