which is the "C" drive? Geoff Cox 07-05-08

Hello,

I have a PC with 2 SATA hard disks in it (logical C and D drives) and
wish to replace the "C" drive with a new hard disk.

How do I know which is the "C" drive in the case?

I once before got the wrong and the PC tried to boot off the "D" drive
which then made the files on this disk inaccessible.

Thanks

Geoff

If you open Disk Management, Disk 0, (which may or may not be your
boot disk), will be connected to SATA 1, and Disk 1 will be connected
to SATA 2. That's if they are connected to the Southbridge SATA
connectors. If your drives are connected to an additional SATA
controller, such as a jMicron its connectors will assume SATA 0 and
SATA 1.

Ian,

Thanks for the info.

Going to Disk Management I see that

Disk 0 is C:

Disk 1 is D:

but no mention of SATA - so far I haven't found anything to tell me
which is which drive when I open the case - have I?!

Cheers

Geoff

If the drives are not identical, you should be able to identify each in "my
computer", but then you'll have to be able to read the nameplate on the
drive to know which is which. You can also take a 50-50 shot, and just
disconnect one. The worst thing that'll happen is the machine won't boot.
Then you'll have to remove the non boot drive , in the bios, from the boot
order

'afraid the drives are identical in make and size!

plus! as I said I had the previous bad experience with the 50:50
approach in that the PC failed to boot off what wa the D: drive but
after putting the C: drive back I couldn't access the D: drive.

can I tell which is which from the cables?

Cheers

Geoff
