Adding IDE drive to SCSI system
System: Adaptec 2940U2W
IBM 9LZX 9 gig h/d -2- Plextor SCSI CD-ROM's Castlewood Orb 2.2 Gig removable drive Win98 FE + updates Have tried to add a Western Digital 120 GB IDE drive to the system, setting it up to only have an extended DOS partition with -4- logical drives. However, when I run FDISK, it shows as Disk 1 and it keeps giving me a message that I have to create a Primary DOS partition. It shows the SCSI boot drive as Disk 2 (drives C, D, E, F) and the Orb drive as Disk 3 (no drive letter assignment; in Win Explorer, it shows as Drive G). Well, I don't want to !! If I do that , then the drive letter assignments on the existing SCSI boot drive become screwed up. I just finished adding the same model drive to another system (all IDE) and had no problems doing the extended partition & logical drive(s) setup on it. BIOS settings are set so that the boot order is "SCSI, A, C". Have enabled the IDE ports on the motherboard; the IDE drive is recognized properly. IDE drive is jumped as a "single drive". What do I need to do to make this work ?? thanks ray |

Hi,
I had done something like it before, waht I had to do is to disable the "AUTO DETECT" feature in the BIOS, so that the IDE drive wouldn't be recognized by the system, but once in Windows everything was working perfectly. Windows detected the drive and set it up with drive letters after the SCSI drives. but the order of the drives was all IDE HDD first, and then SCSI, but the main thing was that the drive letters were correct -- Good Luck Bonne Chance Martin "thinman" wrote in message news:w5Xoc.36575$pJ1.11116@lakeread02...

What do I need to do to make this work ?? thanks ray The BIOS for the motherboard loads before the BIOS for the SCSI controller. That means the IDE ports are scanned first. Adding an IDE hard disk means it will be detected as the first physical drive rather than those on the SCSI controller. See http://support.microsoft.com/?kbid=51978. Driver-only support drives, like CD-ROMs get assigned last (because they aren't found until the OS loads their drivers). Windows NT/2K/XP are different in that they put signatures on the disks in the MBR and record them in the registry so the drive letters will remain fixed even after adding more drives. You won't have that in Windows 98. This problem isn't just with SCSI. If you use an IDE controller expansion card the same thing will happen because the BIOS for the expansion card loads after the BIOS for the motherboard. Maybe configuring the motherboard's BIOS to boot from SCSI might make it the physical scan order change but I doubt it. You could also try NOT defining hard drives in the BIOS (i.e., leave the IDE ports enabled but configure NONE for drives in the basic drive setup screen). -- __________________________________________________ __________ *** Post replies to newsgroup.

Win 98 always assigns IDE drives their letters BEFORE it assigns SCSI
drives. If you combine IDE and SCSI drives with Win 98, the boot drive must be IDE. Time for Windows XP, perhaps? -- DaveW "thinman" wrote in message news:w5Xoc.36575$pJ1.11116@lakeread02...

Nope, the boot drive most certainly does not need be "IDE" for Win98, nor for ANY other OS for that matter. The choice of boot drive is a pre-OS condition, has nothing to do with the OS used, rather is a feature of any bios made in the past few years with rare exception of when an OEM might, through bad judgement, hide and disable this standard feature. |

Well, the only way I got it to work was to run FDISK
from within Win98 (dos box) . The IDE drive came up as Disk #3 and all that was left was to set it up as an extended partition and -4- logical drives. As I speak, ScanDisk is running to verify media integrity (?); started it last night around 9 pm and it's now 8 am and the first 12 gig partition is approximately 80% checked. Don't think I'm going to do the remaining 145 gigs+/-. Thanks for the suggestions. Have saved the posts for future reference. Ray. "thinman" wrote in message news:w5Xoc.36575$pJ1.11116@lakeread02...
