Got a Lexar 1gig CF card, was copying some files, copied them all ok but next time I started the machine and went to access them it kept saying its couldn't recognise any card.

Tried it in several other machines and zilch, cant even reformat it as its not even recognised.

It hasn't been dropped, smacked, heated or anything like that, is it possible for one of these cards to screw up for no apparent reason?

Dont suppose theres any recovery gadget out there that can fix it?
