greetings, it has been a long time and i do not recall all the specifics if one loads CentOS Linux on a machine with an PATA IDE or SCSI hard drive interface then i should be able to interchange that drive on virtually _ANY_ machine with an PATA IDE or SCSI respectively right?? (ignore physical connector differences on SCSI) i believe the answer(s) to be yes... now, what about the newer SATA? will it hold true there as well or are there enough minor differences in SATA creation and growth where one could run into an occasional problem? the bottom line appears to be that almost _ALL_ relevant hardware drivers from the past and the present are included in the distribution correct? can anyone comment on any major recent "gotchas" or other relevant situations they experienced in moving drives from machine to machine or ??? tia and regards, - rh -- Robert Hanson Abba Communications http://www.abbacomm.net
