The hard drive appears to have gone belly up on my 9890 (tries to boot but gets stuck with desktop half loaded even in safe mode and a chkdsk from recovery console won't even attempt to run, immediately kicking out an error that "this volume appears to contain one or more unrecoverable errors").

So my question is what hard drive do I need for a replacement and where can I find one? Thanks in advance for your assistance!

PS.. This is a non-raid model although did need to load promise drivers to get it to work.
