Selected partition is not formatted

Posted on 1999-01-11

I have partitioned and formatted a 6.4GB hard drive in an IBM PC 350 (6587 model), installed OS/2 WARP4 and other software. When I reboot I select drive C: from boot manager. Everything works OK. I then physically remove the hard drive from that machine and place it in an IBM PC 350 (6586 model). When I select drive C: from boot manager I get a message "Selected drive is not formatted" and I can't go any further. The drive I am using does work in the IBM PC 350 (6586) when I partition and format it in the actual machine. I only have the problem when I migrate from one machine to another. Any ideas?

What's the date of the BIOS on the IBM PC 350 (6586) model?
Older BIOSes may have trouble with "large" (over 2GB or 4GB) disks,,
and a "flash-update" to the BIOS may be needed.

Also, until you apply an IBM "fix" to OS/2 Warp (3 or 4),
OS/2 will have problems when you try to install it or run it
with an IDE-style disk which is larger than 4GB.

Do both computers support 'LBA' mode?

What's the output from 'FDISK /QUERY' against the drive?

Do the 'LBA' configuration-parameters match on the two computers?

Both Bios settings must be the same for the HD parameters. Otherwise you will not be able to access your system correctly. With autodetect the parameters may not be the same. You have to enter manualy ALL settings (heads, cylinders, mode, ...) to the second PC.

Great minds think alike, or one plagiarizes the other.

Thanks, RBR, for rephrasing my comment,
and then posting it as an "answer".

Since this seems to be the only question ever asked by 'xpbbws',
you will probably be awarded the points when the "auto-grade" function kicks in.
