Hard drive appears twice

By skopas ·
Dear all,

I have a problem with a server.
A hard disk drive, which is the system drive, appears twice with different drive letters. Do you know anything about that?

My guess would be 2 partitions on the same spindle.

Do you have a second HD?

If you do, the possible cause may be either RAID 1 was broken or ghosting was done on the second HD.

If you do not,
1. Spyware or virus might be the cause.

Free Antispyware

1. Ad-Aware SE Personal:
2. Spybot S& Http://
3. MS Antispyware:
4. SpywareDoctor:
5. SpySweeper (trial version):

Free Virus scan

1. Panda Software Activescan:
2. TrendMicro Housecall:
3. BitDefender Scan online:
4. MacAfee FreeScan:

2. Boot to Safe Mode. If it is OK there, run MSCONFIG to find the program that causes the problem. If it is not, MBR may have been corrupted. Run FIXBOOT and FIXMBR from Recovery Console. You may also try FDISK /MBR after booting the computer from Windows 98 Startup disk.
Make sure to back up data before trying these.

I have seen this phenomena if the RAID is made up of SATA drives. The drives will appear as C and D or E and it is perpefctly normal, that is the way SATA RAID works. Another reason why something like this appears is if you have the good old DOS Subst command invoked to run some hard wired DOS application. Check this possibility

At last, I have the answer. The problem is that I have dynamic disks on the server, not basic ones. The problem appeared when I installed the Windows 2000 SP4 Update Rollup Pack. The actual problem is that the System Disk becomes mirrored.
There are three solutions to this issue:
? Remove the Windows 2000 Update Rollup Pack and this can be done using Add/Remove programs. This should however only be attempted when the system is running on the "C:" (you need to check this by opening a cmd prompt and typing "set windir").
? Apply v2 of the Windows 2000 Update Rollup Pack. This is a Beta version, so it is not recommended.
? Change dynamic disk to basic disk. There are several programs which can help you to do this. Maybe you will loose Data, so it is not recommended, too.
