Question : Find  \Device\Harddisk1\Partitio<wbr />n1 in Windows NT 4.0 (bad sectors)

hi experts I get the event 7 (bad sector in \Device\Harddisk1\Partition1)

Problem is can't figure out which Harddisk is meant
I have four harddisk, one cd-rom and one tape drive

As far as I understand there is a RAID 1 installed on disk 1 and 2 (with two partitions), and another software raid 1 on disk 3 and 4 (with only one partition)

First, I followed the instruction given here:
http://support.microsoft.com/kb/159865/en-us

But I couldn't find a targetId=1.

So to what does \Device\Harddisk1\Partition1 actually refer?

Hope you can help

You can also try going to microsoft.com and download sysinternals suite.http://technet.microsoft.com/en-us/sysinternals/bb842062.aspx

If you run diskext then it will give you a map.  Also ntfsinfo provides good info.  

But, whether hardware or software RAID, the problem is one of these:

1. You have a drive failure and the system is running in degraded mode (half of the RAID is offline), and surviving disk has unrecoverable read error.  (Make sure hardware is OK and all 4 disks online and no errors in RAID event log)

2. The RAID is not degraded, and both disks happen to have an unrecoverable read error at same block (unlikely . data is bad at that block so you need to scan using some software to find out what file is involved -- more tricky but let's eliminate 1 & 3 first as they are more likely)

3. Filesystem corruption (run chkdsk /f) so that the filesystem thinks that a chunk of the file is on a block that doesn't exist, i.e, the next block number is higher than the highest possible block number for your available storage.
