I did chkdsk two nights ago, which said “volume appears to be ok so no check was completed. to check anyway, use /p.” So i did chkdsk /p, which gave me “one or more errors was found on the drive.” I didn’t know about chkdsk /r. I’m running it now.

How do I check that my RAM is good?

If not WD or Maxtor, then who? Seagate? http://shop1.outpost.com/product/4596277
