Removing the memory hack is quite easy.
I followed
Random667 and
Skinski solutions (thank you guys) with some slight changes.
So that's what you've got to do:
1) Use Check Flash 1.10
2) selected the drive, selected as a “physical device”, Selected “low level initialization”. Hit Start.
3) In the new window, you should see 4 empty partitons!
Select the 0 (zero) one.
4) Click new, and create a FAT32 partition of 3.84GB
5) After finishing with CheckFlash, format the drive in Windows (I use XP)
Viola!
I've done all that and it still shows as 32gb :-( I don't know if I'm doing the right thing when the program tells me to "replug device"?
Anyone had similar issues?
