I have two basic hardware questions, concerning hard drives in trays
which plug into the computer.
Firstly, if there are several hard drives, each with a different OS on,
should they all be of the same make and model? Will booting from drives
of different makes "confuse" the BIOS, or doesn't it care?
Secondly, does it matter if some trays are labelled UDMA133 and others
UDMA60/100 - assuming they all slot into the same carrier?
Hope the answer to both questions is that it doesn't matter - it'll get
me out of a bit of a mess!!
Sorry this isn't directly related to Mandriva!
Thanks for any advice.

If you are cold-plugging the drives, and the BIOS is set to auto-detect
the drive on boot, then the drive size does not matter. If the BIOS is
set to a fixed size drive, then you may have to go into the BIOS and
change settings if you want to use the full size of the drive. This
depends on the OS installed - if the OS does not use the BIOS
information in determining the drive configuration, then as long as the
boot loader can find its files, it doesn't matter what the BIOS thinks.
If you are how swapping drives, then the BIOS doesn't matter. The OS you
are running has to be able to handle the drive change. (And the hardware
has to be rated for hot swapping!)
As far as the speed ratting, it probably does not matter. It would not
supprise me if the carriers are the same, but some were built before
UDMA133 was introduced. If you are not using UDMA133, then you definitly
will not have problems, as they will all work with the slower transfere
rates. If some of the drives you are using do not support UDMA133, then
use them is the UDMA66/100 carriers just to be on the safe side...
