Beat the Theives

momentusSeagate has developed DriveTrust technology which automatically encrypts all the data written to the disk, making it inaccessible to anyone who doesn't have the correct password when the computer first boots up.

"There is no processor and memory consumption, because the encryption is all happening down in the drive. Tests we have done internally have shown minimal impact on throughput and write-read performance." said Scott Shimomura, senior product marketing manager at Seagate.

DriveTrust is already available in Seagate's DB35 disk drives for digital video recorders and other digital entertainment devices. The company plans to ship a hard-disk drive for notebooks that features the technology, called the Momentus 5400 FDE 2 in the first quarter of next year. The encryption on the Momentus drive will use a 128-bit Advanced Encryption Standard, or AES, algorithm. It will be available in capacities up to 160 GB.

Sounds great doesn't it?.. Unfortunately the boot-up password required to unlock the data on the disc could also prove to be a weakness in the DriveTrust protection. The encryption is unlocked as long as a computer isn't completely switched off, meaning potential problems with Windows Vista, which by default goes into "hibernation" mode, instead of shutting down.

I for one wont let this put me off, for starters I won't be using Windows Vista, and secondly any protection is better than none.
