Puzzled over over the relationship between the partition and geometry of hard disk.

Not sure why solaris couldn't detect the geometry of a hard disk which has a working OS of winxp pro.

Is it due to the different OS that the partition information is stored in different location?

When I type '"format" it is shown as below,

c3d1 < drive type unknown>
/pci@0,0/pci-ide@1f,1/ide@0/cmdk@1,0

I was quite puzzled, since it is unknown to Solaris, that means, Solaris wouldn't know the disk structure, however, i could mount it as ntfs-3g and copy files onto it.

Anyone here can explain this and would be much appreciated!

Thanks...

First of all, did you check if the hard-drive is supported on a SUN machine?

it is an IDE hard disk..it is 40GB western digital .

Sorry Im not asking for this. Whats the system model? A SUN server ONLY supports HDDs of certain part-number provided by SUN. Not any disks. Not recommended at all.

If the drive type isn't discovered automatically via format. I believe the only other thing you can try is manually setting the cylinder counts and what not. You'd have to lookup the drive at the manufacturers website to get those details. Still no guarantee that it'll work correctly though, since its most likely not supported.

Ops.. i;'m using a x86 machine..
