Adaptec 2400a and failed harddrives

At the moment I have the following problem:

When I look in the bios of the Adaptec 2400a (By pressing Ctrl A at bootup)the first drive of my aray is missing:

(0,0) Missing Compl

And the status of the array is: "Degraded"

The systems boots normally into Windows 2000 and everything works fine.

My Question is: How do I get the drive back in the bios of the controller without loosing any data? (Does the Raid 5 still work at this moment?)

I have experienced simular problems before.

The first time the status of 1 of my drives was "failed". I replaced it with another 60 GB drive, deleted the raid 5 array end created a new one (unfortunately I lost all data in that proces). Then I tested the "failed" drive and it worked perfectly fine.

The second time I had one "failed" drive and one completely missing drive. The status of the array was death. When I deleted the array and created a new one (this time without replacing the failed and dissappearing harddrives), all the drives where the again and the status was "optimal" for all drives.

I don't think the drive is defect this time (Not any of the drives was with the former problems). But I would really like to know why the drives dissappear or get a "failed" status and how I can solve the problem. I have the latest bios version for the Adaptec 2400a (It was allready in there).

Strange thing is that Windows is still booting and working properly. The other 2 times Windows could not be booted anymore. Update! Windows doesn't boot properly anymore.

I don't think this is the solution, because the harddrives where perfectly ok last time (And I think the drive will be this time). Is the controller itself the problem?
 
A RAID 5 array will work with one drive dead (More can die if you have hot spares and there is enough of a delay to rebuild).

I would follow their advise and go into the Adaptec 2400 BIOS and mark the drive hot spare.

I have no idea why your drives are disappearing and failing. When the drive disappeared did you try to reboot to get the drive to reappear? (The death status tells me that your RAID 5 array can handle one failed drive, but not two -- this is the normal RAID 5 situation and they only thing some RAID 5 controllers support).

If you can take the drives that are failing and put them in another system format them, do a surface test, and they come out fine, then I would bug Adaptec into explaining why the drive failed if it is a perfectly good drive.

Disclaimer: I have not worked with IDE RAID only SCSI RAID. I have worked with Adaptec SCSI RAID controllers.

I really doubt that the problem here is with anything other than the Adaptec 2400.

I have a bunch of friends that used to work at Adaptec in their QA department, but were layed off with most of the rest of the QA department last year. Too bad I can't get them on here to answer these types of questions. They probably signed a contract stating they wouldn't provide Adaptec support for X years after leaving the company anyways.
