IDE & Geometry & Portability of disks between controllers

IDE & Geometry & Portability of disks between controllers

[bert hubert]

Recently I moved an IDE disk to another machine and some weird things
happened.

LILO booted from RAID and both halves of the RAID mirror were transplanted to
the new machine. 

1) When booting 'LIL' appeared and then nothing happened for a few seconds,
   after which the final 'O' appeared, and the system would boot normally.

2) Booting worked but writing to the mirror quickly lead to very bogus
   'attempt to access beyond end of device' errors.

Not, this together leads me to the question - should I expect to be able to
move an IDE disk from one machine to another and have it function correctly,
always? 

Thanks for your time.

Regards,

bert
