I just got an Pioneer DRM-604 SCSI CDRom Changer.

What is the best filesystem-driver to use with the Amiga?

I know ASIM-CDFS will work.  Is it the best? what about OS 3.9's CDFS?

What are your experiences?  I never had a CDRom Changer before.

Hmm, afaik ASIM-CDFS is the only one that has a choice for one in prefs.

Do you remember this quote, "There can be only one!"  

Regardless, it is not the file system per se, but the controlling software; ASIMware's CDFS know to use the unit numbers of the SCSI ID numbers.  You are aware that an A2091 (for example) uses ID #7 for the controller, leaving you 0 to 6 ID numbers for your device.  Each device can have 7 unit numbers: a CDROM changers set to be device 3 will access each of its CD Drives by the unit numbers (0 to 7).  There by each drive gets a number like 035 where the drive is unit 5 on device (ID#) 3.

You can do this by hand and set up a mountlist for each drive in a changer, or just use ASIM-CDfs that also allows each drive to be used with a GUI.

AS I recall, you can have up to 7 controllers or so, in your computer, in which case the mountlist might contain "235" for controller 2, ID 3, drive 5.

Thanks for both or your replies.

I will try using ASIM-CDFS.   I own (actually multiple versions as always got the upgrade) ASIM-CDFS since AmigaOS 1.3 through 3.1.   I started using the internal file amiga CDFS at 3.5 and above.  more or less I was wondering if there were better configuration or easier you use configurations or more powerful configurations than ASIM-CDFS offers.

I think with this some units you are partly correct.  I think some of the CD changers are set up the way you describe, but some use luns.
 I think this one uses luns (as this is a Six disk changer).  So you really need a SCSI controller that can handle Luns, like an A3000 internal, or a gvpscsi.  If my memory serves, (it as been a while) the 235 you are referring to is correct, the 2 is controller, the scsi ID is the 3, but the Luns or "drive" is the 5.  (correct me if I am wrong).  Most fixed hard drives have a lun of 0, but drives with multiple media (like a multi card reader) have multple luns with one id,  so the CD changer is "probably" lun 0-5.  Otherwise you would quickly run out of Scsi IDs which is not the case with may readers.

No need to correct, you are right.

When I say Unit Numbers, I mean Logical Unit Numbers or lun's.  The "logical" part of that seems not needed IMHO.  Mike is correct, Mech's SCSI card readers use the same thing.

Had one of these when I ran my BBS and used ASIM with great luck.

Was an absolute delight watching BBS users hit the CD changer, rotating discs, pulling files remotely :)

Back then, the concept of 700+ MB x 6 online on a BBS, on demand, was mindblowing.

Duce, very cool!  It will be fun to try replicating such a thing.  I have a couple fred fish disks and a couple older aminet disks.
