GAZZA's MAXIM: The bigger the storage, the more you lose in one go when your drive craps out.
Earlier this year I used partionmagic to quickly set up a new WD drive. After it was formatted, I filled the drive completely with stuff from from several drives. The whole thing worked fine for about a week, then the data disappeared. The drive was still good, just the whole drive was empty. Got on the warez newgroups and DLd every drive and file recovery software I could find, but only recovered little fragments here and there - directory structures and a couple files each, mostly all corrupted. Luckily it was all music and audiobook mp3s and box office movie and TV show video files, not porn LOL
Anyway, eventually I re-parted and formatted the drive, using Windows setup and the old slow method. The drive has been fine ever since. Nothing like losing "roughly" 200GB to sober you up though. All I could come up with was that the "quick" format method doesn't lay down as strong of a magnetic "roadway" for the info as the slower formatting. Don't know if that is true, just something to think about. I had heard it from one source in the past, though it escapes me at the moment.
I'm still looking forward to getting a few of these drives though when the price falls.
