I did not test this assumption, thinking that powering on the drive while running may injure the drive, yes/no? I believe (all asssumptions on my part as well) that the hot swap issue is a harddrive recognition issue. The IDE drive is preconfigured in the bios and recognized at boot. I surmise that one could hot swap an IDE drive if the swap is between two identical drives and one of the drives was recognized at boot. SCSI drives (more assumptions) in Win95/98 may offer more options. One can refresh the SCSI controller in Device Manager. You can add SCSI components and recognize them without a boot. It works for scanners and removable MO drives. I do not know how it works for harddrives. If my memory is correct drive letter sequences can be affected this way. When I tried it with the MO drive the drive letter was assigned after the CDROM..it normally is assigned before the CDROM. Does anyone know if there is a way to 'refresh' a SCSI controller in NT?..Linux?? Zeuspaul

Mowa What do you mean by "hot-swappable Zp's assumptions about drive lettering sound correct. I am able to remove one of two identically configured and matched (two of same drive maker, model, size) IDE drives, with the computer running, and the drive letter stays the same. I'm using Dataports (not DataStors). I don't know if these are different as far as hot-swapping goes. When I was researching removable trays it was a little confusing as to which systems where hot-swappable and which were not or if they all were. One of the things that tipped my scales toward the DataPorts was that they came right out and said, in plain English, that their units were hotswappable. I was under the impression that I would need a special (IDE) controller to actually add/remove drives while the computer was running. No don't need anything other than your regular IDE controller. Just make sure the drive activity light is not on and wait an extra minute after that to turn off the power switch on your frame and pull out the cartridge and drive. thinking that powering on the drive while running may injure the drive, yes/no? Computer running no. Drive running yes..injury definite. The drive must not be accessing data when you turn off its power. Turning on drive power when computer is running is ok. Again this is how the DataPorts work and I would assume others also but I don't know this as fact. Maybe reviewing the DataStor docs and web site would either confirm or negate similarities with DataPorts. Clarence
