yes an no as ted explains the cpu when loading a hd makes up a macro of the hd catalog this lets it see all the folders on the hd when you remove a disk and insert another it still has the other disks catalog and can put errors on the hd or cf card or zip
the proper way to do it is to change to floppy drive first before removing the hd zip cf this then lets the cpu to look at the floppy disk and its catalog and so deletes the information of the hd in its memory and as there is no disk in floppy will just let you know now you can remove the hd cf zip and place in the new one when you access the scsi it will do a new look up catalog table of the cf hd or zip this stops you from errors
some samplers like the asr10 and eps16+ if you dont do the floppy trick and remove a cf card or zip and put in a new disk and then you try to load something it goes on a constant loop looking for the original macro catalog file that was previously stored in its memory
i have had others akai mpc3000 that get checksum errors by just swapping cards and adding extra samples and it has added corrupted data the proper way to do it is to change to floppy drive first before removing the hd zip cf this then lets the cpu to look at the floppy disk and its catalog and so deletes the information of the hd in its memory and as there is no disk in floppy will just let you know now you can remove the hd cf zip and place in the new one when you access the scsi it will do a new look up catalog table of the cf hd or zip this stops you from errors

remember this devices came out before removable drives when a 20mb drive was considered huge at the time the syquest drives came out a little later but still samplers have never had the atapi protocol but do have rescanning of scsi bus so that the catalog tables could be updated
the asr10 works properly like this and not crashing the machine

-TYMMV, but again, I don't recommend swapping flash.A zip drive works more like a floppy and has a disk change sensor in the mechanism. Flash media drives don't work in quite the same way.I am just going by my experience.... Hot swap of flash type media have given me corrupted catalog / HD errors .. happened to me on different drives on different Emaxes....

Interesting. Is this true for any drive connected to the scsi chain or just the boot drive can't be hot swapped?I don't own a Zip drive but I was under the impression you could swap one of those disks w/o powering down. Is that not true?Thanks,Jim
