In regards to Lacie.
Many people have had huge amounts of success and reliability with the older Lacie drives. I'm not surprised at all that your 160GB drive is still working fine.
I work at a film school helping with post production, and we used to recommend all the student purchase Lacie drives. In the last year and a half we have had MANY Lacie failures. The drives themselves are usually not the problem, but the chipset/enclosure. Seems that the chipset or board is corrupting the data structure on the drive. Sometimes its recoverable if the drive is removed right away and then recovered in a separate non-Lacie enclosure.
Also Lacie uses a variation of drive manufacturers in their enclosures. Sometimes you are getting a western digital, but I've seen LOTS of Maxtors in there.
I think 2+ years ago Lacie was great, and the creative professionals used the drives and had good experiences, and still do with those old drives, but now, there is no way I'd buy a Lacie.
Just my 2 cents. I own about 3TB or HDD space, and I only trust seagate.
I know seagate bought Maxtor, so hopefully they will rub off on them, but only time will tell.
GOOD LUCK.
