Usually I run WinNT 4.0 SP5 on my machine. I am using Drive Image to backup
my U2W SCSI hard disk (IBM, 9GB). The HDD is partitioned in 2 primary NTFS
partitions, 1 logical NFTS and 1 logical FAT partition. All is fine and
recognized under NT.
To use DI, I have to boot into DOS. Drive Image provides OpenDOS 7.01 for
creating boot disks. The theory is that the FAT partition should be
recognized as a C drive under DOS. Unfortunately, it is not recognized.
Here's what I attempted so far:
DOS recognized an IDE drive (FAT formatted logical partition, 860MB) as
drive C, and DI was happy producing my drive image using the same boot disks I
use now. As I have onboard SCSI (ASUS P2B-S board), the IDE HDD prolonged
booting, and I decided to get rid of it again.
The DOS config.sys has two drivers, first is driver=a:\aspi8u2.sys (for
U2W SCSI), second is driver=a:\aspicd.sys with some parms also referenced in
autoexec. My CDROM/CDRW drives (also SCSI) are recognized and readable.
The aspi8U2 driver installs just fine via 13H interrupt. So the theory is
that the FAT partition should be readable.
Are there special parameters for the driver to be used that I do not know
about? Are there restrictions in OpenDOS for the order of partitions on a
HDD? (The FAT partition, 850MB, is physically last.)
The SCSI BIOS has recognized all three devices with their correct SCSI id,
and Drive Image can get all information about the HDD to be backed up. It
just cannot write the image file as there is no C drive under DOS. (Invalid
drive specified is the error message from a dir c: command).
Any idea what I might be doing wrong is greatly appreciated.
