Changing a partition's device name
« on: April 11, 2006, 02:13:44 PM »
Is changing a partition's device name (e.g. HD0) destructive? I have just installed a replacement hard drive and want to change the partition device names to what they were on the old drive. Can I do this without losing data? The partitions are formatted with SFS under OS3.9.

You can do this in HDToolbox.

Copy the data over first from the original drive.  Then remove the original drive or rename its partitions. The rename the new drive to you desired labels.

It is important not to have two drive with the same device labels.

Thanks - that's what I thought. I'm familiar with the fields in HDToolBox but didn't know if changing from QDH0 to HD0 and QDH1 to HD1 would destroy the data within the partition.

I can't be totally certain, but I didn't think changing the labels destroyed the partition.

I know for certain that I've done it myself years ago, but I can't remember having any problems afterwards. I did have an RDB problem about a year later, but that's probably unconnected.

I'll try it. If it does destroy the data then it's still on the IDE drive anyway.

Changing partition name is safe. Using same name twice is safe too, the system temporarily renames duplicate partition to something else.

Hi mate, no not yet. The hard drive I have just installed is also SCSI, so now that is working I know the SCSI controller and SCSI chain are ok, and the problem must lie with the CDRW drive. I'm going to try a lens cleaner and see if that helps.

Cheers

You can do this at any time without damage. You can change almost everything in HDToolbox as long as the position, size and organisation (block size, file system) of the partition does not change.

And even then, HDToolbox warns you before it saves any destructive changes. And even the warning might be too pessimistic. If you know better what you are doing, changes causing warnings might not be destructive. E.g. changing filesystem from FFS to MuFS. Or from PFS3 to PFS3ds.

Bye,
Thomas
