I have a 3Ware 6200 with the latest firmware with a pair of drives in a 
RAID1 config.  One of the drives flaked out, the 6200 marked the drive 
as bad, and kept on running - all is good.  I replaced the failed drive 
and tried to rebuild the array, but original drive that's still on the 
6200 comes up with a read error towards the end of the disk and the 
firmware aborts the rebuild.  Help!

3Ware says the latest 3dm on Windows and Linux has a "force rebuild" 
option that will ignore read errors during a rebuild.  Unfortunately it 
doesn't look like this option is available from the 3Ware BIOS or from 
the FreeBSD version of 3dm.  Does anybody know a trick to initiate a 
"force rebuild" short of booting Linux or Windows on the box?

Any other suggestions on recovery?  I'm down to either booting Windows, 
rebuilding the array, and then replacing the second flaky drive; or just 
giving up and doing a complete reinstall (after replacing the flaky drive).

Any comments on FreeBSD's support of 3Ware these days?  It appears that 
after Mike Smith left the project no one has done any significant work 
(e.g. getting the latest 3dm).  I don't exactly feel comfortable with 
the 3Ware/FreeBSD combo any more.

Jim
