Disk Number Assignment ?
In Disk Management I see that disks are assigned numbers.
Is primary master always designated as "Disk 0"? Primary slave always designated as "Disk 1"? Secondary Master always as "Disk 2"? That's the way it is on my system, at least right now. Could anything happen that would change this disk number assignment? One might think that "Disk 3" would always designate a Secondary Slave disk. But on my system, I don't have a secondary master drive installed, and so a USB Compact Flash reader is designated as "Disk 3". |

The disk numbers are assigned dynamically following the 'first availlable' rule. If you take out the primary slave then next time a different drive becomes disk 1, the secondary master if it exists. The order is as you described for IDE drives. I don't know how it works for other bus types. Uwe |
