hi, it's somewhat known already how to attache a scsi-device to a running system (echo "add..."> /proc..), and it works well. but what if you deattache a device. i want to move my external dat-streamer to some other machien. is there any harm with just plugging it of an runnung system? i expect so. is there a distinct way to deatache propperly? something like `echo "remove..." >/proc...`? gerhard
