- answering and fax machine.

- external case a3k case
-
- using that setup causes every 1 to 3 days a system lockup (mousepointer
- freezes) or read/writeerror requester popping up for harddisk volumes. if i
- hit the retry gadget the system continues it`s work. not very funny if i`m
- not at home...
-
- now i removed the cdrom from the setup...

- external case a3k case
-
- ...and everything worked fine. if you consider two weeks without a guru or
- lockup and 2 gb dat backup plus verify as ok.
-
- now i added the cdrom again and tried several setup variations:
- - removing streamer and scanner from the chain - still lockups and errors
- - removed the external terminator and terminated cdrom internally - again
- lockups and errors.
-
- and i swapped the cdrom filesystems:
- - original amiga dos 3.1 cdfilesystem - lockups and errors and it
- recognises a cdrom in drive only if inserted after mounting cd0:
- - asim cdfs 3.5 - lockups and errors
- - amicdfs 2.10 from aminet - lockups and errors
-
- so, almighty amiga gurus, i ask for help.
