So I emailed them, and complained that this is the second failure, that has died a couple of months after warranty period... and I asked if they can fix it at their charge. They said NO, and want $115 for the repair, which is more than the cost of the drive brand new. How is that for service? Plextor customer service is bull. Their RMA *ignores* e-mails that does not come in with a special form filled out. If you fill it out incorrectly, they will ignore it. For example, one of the items on the form is a serial number you obtain on the back of the drive, essentially you have to dismantle the computer to get it out. What a pain in the butt! If you don't fill that number in, they ignore you.
Anyway, Plextor is BAD NEWS.
