When moving large files (ISO, movies and so on) there is a noticably higher CPU time, and you can forget the use of DMA transfers, you're up into CPU level again. however.. partition recovery... OUCH OUCH OUCH. I had a glitchy cable on an IDE drive, with an 80 gig encrypted partition. All data got completely unrecoverable due to both that. Directory indexes were permanently fucked up with errors after the encryption was done.. Very upsetting for me at the time, and has made me re-evaluate the use of encryption for such cases. Loop-aes is decent, but requires patches to util-linux to make it work. dmcrypt is more official and actually appears to be a better implementation on the paper. (ok. there was an issue with the IV's but thats so far out on the theoretical display that its hardly funny anymore) //Spider -- begin .signature Tortured users / Laughing in pain See Microsoft KB Article Q265230 for more information. end
