remotely encrypt flash drives

hi all,

i recently lost my 4gb titanium cruzer flash drive, and it has some private files on it. is there anyway I can remotely disable/lock/encrypt it via my account, etc.? (i have nothing security-wise on it currently.)

no, the drive doesn’t not have any of these capabilities. 

Are there any commercial programs that can do that?

definitely none that could be used after the fact. and no I am not aware of any software that could do this. enterprise level secure usb flash drives have a remote erase ability but you they are managed by a server much like a work PC on a domain.
