Is there anyone who can be trusted to supply a disk that actually works!

I crossed Samsung off a long while ago thanks to the F1. (3 out of 6 HD501LJ's still working, 4 of 4 HD103UJ's drop off the bus occasionally.) so far 6 HD154UI's working ok as long as they are not plugged into a Marvell 6145 sata controller.
Seagate (1.5TB drama & seizing spindles, I have 2 out of 4 seagate 500GB still working).
Hitachi, I have a 1TB HDS721010KLA330 which randomly loses it's partition table but only when connected to an Adaptec sata controller! Otherwise it's good :-P
WD, (power management bug).
Many Many dead Maxtor Diamondmax 9 drives, usually a week out of warranty.

No we don't get lots of earthquakes and thunderstorms here.

Does that leave anyone? The Intel SSD I bought last week hasn't failed yet ;-)

Thanks for the warning, I was about to buy 2x 2TB drives for a raid 1 next week, I think I'll be buying two different manufacturers, hopefully when they break it will be in different ways and hopefully at different times!
