I've had 4 of the 75GXP models fail on me, 2 where in RAID-0, then thought maybe it was the drives that couldn't handle the RAID-0 so when i go its replacements back from IBM i just used them as a single Master and Slave drive on my Promise ATA-100 controller, 3 months later both burned out about the same time, i looked at the serial numbers and they were both off the same line next to each other. Have not called IBM yet to replace them
