Hard Disk Crash predicted: Which one?

[SaSi]

In Event Viewer, I noticed the following message appearing almost once a day for the past 3 days:

The driver has detected that device \Device\Harddisk2\DR2 has predicted that it will fail. Immediately back up your data and replace your hard disk drive. A failure may be imminent.

Data:
0000: 0e 00 03 00 01 00 5e 00 ......^.
0008: 00 00 00 00 34 00 04 80 ....4..€
0010: 02 00 00 00 00 00 00 00 ........
0018: 00 00 00 00 00 11 2d 00 ......-.
0020: 00 00 00 00 00 00 00 00 ........
0028: 00 00 00 ...

The problem is, DR2 is not a meaningful designation for a drive. I have 8 HDs on my system. Obviously drive letters don't mean a thing because I changed drive D: to O: yesterday and Event log still shows DR2 as imminent for failure.

The disk arrangement in my system is as follows:
Primary Motherboard IDE controller:
1 HD as master in first channel (C: - OS)
1 HD as master in secondary channel

SATA controller on southbridge chipset
2 HD attached

GigaRAID IDE controller
2 HD in primary channel
2 HD in secondary channel

And I am running WinXP-SP2. Anybody has experience as to what this "Harddisk2\DR2" means? I looked the whole thing up in Microsoft's knowledgebase and support sites and the only relevant hit was the following:

http://support.microsoft.com/default.aspx?scid=kb;en-us;830051
which relates to Event 51 and Windows 2000 SP4. Event 51 (although close), has to do with cache not supported by a drive. And I am not getting tons of them. Only one per day.

Thanks in advance to anyone who can help.

I don't want to give you any wrong information on determing your drive #, so I won't

However, if you have S.M.A.R.T atributes turned on in bios, you might be able to determine the bad drive using an small app called DTEMP

Just unzip and run it. It will load into your system tray. Right click on it to see the SMART attribute info.

Thanks a lot for the link. DTemp verified my suspicion that the offending drive was one of the brand new SATA drives. Thankfully it also displayed the serial number of the drive (and thankfully Western Digital records serial numbers to their drives) so I am able to easily identify it.

Again this proves the theory that a HD will fail either within the first month or after a long time.

I Absolutely agree with that. It will either die immediately, or after 5 years.
