Sounds like the same basic description of my unit. Basically just an old
style type AT case and power supply with the 4 drive bays. My unit
includes 2 bridges that have to be cabled in serial with each other if
they are to be on the same bus.

The last description sounds like it is tagging each drive by the LUN. If I
recall a SCSI device can have 8 LUN's 0~7. I haven't seen this. But I
only use 2.4.x kernels.

I had the same problem you described when I first purchased my enclosure.
Back then I was using kernel 2.4.18. When I rebuilt using the CVS drivers
it all worked well. I think 2.4.22 kernel had the same shortcoming. I
had to get the latest drivers again. Currently, I am running 2.4.24 and
when I checked my sources I had replaced the ieee1394 tree with current
drivers again. But I do not think it was for the same reason. Maybe
becuase they wouldn't build. But if you desire to build a 2.4.xx kernel I
can send the tree that I am using that I know works. Or you can get the
latest drivers. The difficulty of this process depends greatly on what
distro you are currently running. Be glad to help if I can.

I do not know about any of the 2.6.x kernels or the drivers. Still too
unstable for me. At the current rate, maybe version 49 or so I might try
it. :)

But I have been using my enclosure for well over a year now with a hard
disk, zip drive, and 2 x DVD+RW drives. Works very well.
