Problem:
WD EIDE drives are dropped from an IDE RAID array or system after several
days or weeks of error-free operation.
Of course I looked at 3ware, at WD and in google to find to find an answer. I found both the articles you posted.
One applies to PATA drives, which we don't have. It gives no hint about software versions for SATA drives and I did not find a firmware upgrade at WD either.
The other one applies to SATA drives. When I found this, I checked with smartctl in another machine (smartctl does not see single drives on the 3ware) all the RAID drives. Acoustic management was disabled on all disks. This does not really surprise me, though. 10 krpm disks are probably meant for servers and to deliver high performance - switching on acoustic management by default on these drives would not be very smart.
Thanx anyway,
Oliver

Oliver,
Call 3ware's support, they were kind enough to point out a drive incompatibility I had at a previous job with a 3ware SATA RAID controller and some WD drives! The drives were not performing as well as they should and occasionally one would get flagged as bad when it wasn't. Call 3ware they will be a world of help and their support was good.
