I take it an explicit 'DiskChange' would not be sufficient to take care of this since FFS 'doesn't understand removable media. But, do you know if FFS understands the ACTION_FLUSH packet? If so, a simple program which sends this packet to the FFS could make changing disks 'safe(er)'. -- Aaron Avery (avery@puff.cs.wisc.edu) ({seismo,caip,allegra,harvard,rutgers,ihnp4}!uwvax!puff!avery)
