RE: recovering after a /dev/sda failure on raid1

I would agree about Fujitsu, Hitachi, & Seagate SCSI disks being very
reliable.

Do note that the server-class drives should have consistent mode page
settings and firmware levels from the vendor.  Fixes to most early-life disk
problems boil down to changes to either the firmware or the mode page
settings.  Even the IBM problems can be helped significantly by upgrading
firmware and careful mode page settings.  

There are DOS utilities to check/update these, and I have some tools for
Linux to help check or update disk firmware and mode pages, if you are
interested.

The IDE disk you mention were discontinued a year ago.
In our experiences Fujitsu disks have as low a failure rate as can be

found.

Drives we have used with higher failure rates (SCSI) came from IBM and 
Seagate.
The best failure rate we have seen is from Hitachi.
In the case of Fujitsu, Hitachi, and Seagate the rates are very close.
Quantum/Maxtor SCSI are a bit worse.
IBM are substantially worse.
This is based on our DOA and in service SCSI disk failures over the past 
year.
