Errors on \Device\Harddrive1

Asked by rkricketts in Hard Drives & Storage, Removable Backup Media, Computer Hard Drives

Tags: An error was detected on device \Device\Harddisk1 during a paging operation.

I have a computer running SBS 2003 with two 500GB SATA drives in a RAID1 config. I also have a 500GB external USB hard drive (well, several) that I backup to in rotation.

The two internal drives are configured as a RAID1 mirror at the controller level, presenting a single drive to the OS. I've partitioned the drives thus:
C: = 50GB
D: = Remainder of drive, 450GB

I backup every night using NTBACKUP. Last night, NTBACKUP puked, producing this:

-----Begin snipped from backup log-----
Backup started on 2008-01-09 at 23:29.

Error: The device reported an error on a request to write data to media.
Error reported: Invalid command.
There may be a hardware or media problem.
Please check the system event log for relevant failures.
The operation was ended.
Backup completed on 2008-01-10 at 04:17.
Directories: 26871
Files: 218358
Bytes: 128,669,641,591
Time: 4 hours, 47 minutes, and 57 seconds

Error: D: is not a valid drive, or you do not have access.
-----End snipped from backup log-----

The event log shows this:
An error was detected on device \Device\Harddisk1 during a paging operation.

Couple of questions:
1. How to decipher "\Device\Harddisk1"? Are my two RAID1 drives "\Device\Harddisk0" and "\Device\Harddisk1" ? Or is the external USB drive "\Device\Harddisk1"

NTBACKUP says drive D: isn't valid, yet I can access it fine. At the same time, the USB status in the icon tray says there's an error with drive G:, impartial write (or something), save data to another drive.

So, is drive D: choking? If so, which drive in the mirror is it? Or is drive G: choking?

Any primer on decoding the "\Device\Harddisk[n]" nomenclature? I've googled it but found no joy.

thanks...
