In my experience, the IBM drives with 15gb platters have had quality control problems. I would recommend against buying that generation if you can help it. Of 8 30gb IBM drives about 80% have failed. Of 2 75gb IBM drives, 100% have failed. (This is not a very big test set, I know) Never a complete failure...just an ever growing number of bad sectors...which as far as I can tell, IDE drives are not good at remapping. I don't know the interworkings of hard drives, so my statement there might be completely wrong. You can dump from one drive onto the other in one step. Something like: cd /mnt/new dump -au -0 -f - /dev/ad4s1a | restore -rf - Note: restore needs a /tmp directory that it can write some of its inode lists or something to. Make sure whatever contains /tmp is mounted R/W. ----- Original Message ----- From: "Kory Hamzeh" <kory@avatar.com> To: "Brian Szymanski" <brian.szymanski@cornell.edu> Cc: <freebsd-hardware@FreeBSD.ORG> Sent: Sunday, September 09, 2001 21:11 Subject: RE: EIDE Drive Errors - Please Help! > You're scaring me, man!
