Replacing failed drive in D8300 Promise SATA RAID.

I have a 250GB RAID (mirror) and have to replace a failed drive. Two questions:

1) The dead drive is a WD2500JD - 75GBB0. I can't find one - the nearest equivalent is WD2500JS or WD2500KD. Will either of these work?

2) Do I have to format the drive or is the Promise clever enough to do that?

Config: D8300, Promise SATA150 TX21, 2x DVD, 3GB RAM, WinXP Prof. etc. etc.

Thanks,

Steve.

Any drive 250gb or larger will work, if it is larger than 250, you will lose any extra space on that drive.. Raid will configure the pack to the smallest drive in the array.

Yes, Promise utility should rebuild the drive even if it is raw.

The attempted replacement of a failed drive did not succeed. The rebuild kept exiting after 1 or 2 %. Tried to recover from the other drive, got "Rebuild not applicable". Both old drives, and the new drive all work fine when plugged into the motherboard (non-RAID) SATA sockets.

My conclusion is that the ancient TX2 controller has failed (an early model, it was always a bit flaky, I often had to do rebuilds, but it was never really clear which drive had failed).

Anyway, I'm running without RAID and doing backups onto the new disk.

I'm considering buying a new RAID adapter, perhaps the FastTrack TX2300. Anyone had experience with this (or other solutions)?

"FastTrack TX2300"

Yes that is what I am using in my Dim5150 and it works great so far. 2X250gig WD drives configured Raid0, 128kb stripe size, the default 64kb stripe size did not perform well.

This is not a factor if you are going to use Raid1

Have you updated the firmware for the old controller card? This may cure the flakyness.
