I just keep having bad luck with my RAID 5 array. One drive (out of 4
WD15EARS drives) was dropped from the array due to powerfailure and
rebuild failed because of bad sectors on another drive. I have been
spending the last few days with ddrescue, copying the data from the
drive with bad sectors to the dropped one. The problem is now that the
drive has bad sectors have spread where the md superblock used to be
on the faulty drive (the very last sectors of the drive, right?), so
how do i force it to assemble without it and with one drive missing?
What drives are by the way the best consumer grade drives to use for
RAID operation?
I really, really hope this is the last time i need to ask you guys for help.

Well, just a little bit off-topic, but...:
For me, and probably others as well, it does not harm in any way to keep asking
questions. I find it interesting and insightful reading some of the answers to
these questions.
So please do ask.

So should I just bite it and build a new array? All the really
important stuff is backed up elsewhere, the rest is, well, just crap i
got of the Internet, you know...
One last thing, I've been thinking about. What copying the superblock
from one of the working drives to the defect one and using a hew
editor to change the drive number and alignment? Is there much device
specific data in the superblock?
