180G IBM hard disk

[Jimmy Wang]

Hi,

I have a 180G IBM harddisk. The mother board recognises as a 180G hard disk
but the windows only recognise as 130G.

Is there a reason for that and how would i over come that.

Thanx in advance.

Jimmy

Yes, the OS doesnt have 48 bit LBA support.

and how would i over come that.

Add that 48 bit LBA support.

There are other versions of that for Win 2K etc, search on 48 bit.

I have the same. I've upgraded to SP1 on Windows XP - and it's still
only seen as 137gb by Windows. Help...! I don't know what to do next and
I've been googling half the evening without success...

TIA

Run Disk Management (right click My Computer > Manage > Disk
Management). It should show some unallocated space on the disk.

It doesn't - just shows the disc as 137gb and no unallocated space.
Thanks to Rod Speed who responded as well - however my mobo *does*
support discs over 180gb, and it's correctly recognised in the BIOS and
by the Raid controller. Just not on XP (SP1)

Thanks for responding

What software was used to partition the drive? Maybe it "hid" the
unused drive space.

Pretty sure I used PM8 from DOS.... Things have moved on, however, cos I
*certainly* used that last night. And it recognised the extra space.
XP's disk management lets me create a partition (as does PM8 under XP)
in the 'new' space. However, any attempt to format the partition results
in an error. The error is just "Format failed" - or similarly
uninformative - both in XP and also if I try it in PM8.

Ok, *if* I originally partitioned the drive with XP's setup CD (can't
quite recall now.... I've done so many things!) then the space above
180gb wouldn't have been seen at that time bc it's a pre-SP1 release.
Certainly after installing XP the next thing I did was install SP1.
Soo..o..m my question is, would XP Setup have done something to the
partition/mbr/whatever that now isn't getting changed by all my retro
efforts? I hope that makes sense!

In summary, XP-SP1 now sees that the HD is 180gb. There are 2 partitions
of 60gb and ~70gb and ~43gb of 'unused space'. I can create a logical
drive in that space. I can't format it. Disk Doctor and chkdsk can't
check it.

It shouldn't have. If this drive is connected to a raid controller,
perhaps its driver is causing some problem.
