Help with SCSI CD ROM

Help with SCSI CD ROM

2014-02-06 by <xxxdna@...>

Hi All,

I picked up a S1100 a few months ago and have been slowly working to bring it into the 21st century. It had a dead LCD and floppy drive so I replaced the LCD and ditched the floppy. In its place I installed an internal Compact Flash read (PDC-60B) which is working great. I have one or two 1gb CF cards that I can hot swap and save/load files from. I also updated the EEPROM chips so it is running OS 4.3

I recently decided to get a SCSI CD ROM for use with the AKAI. I have been using SCSI for quite some time with computers/sampler so I know the usual culprits but for some reason I cannot get this drive to work with the S1100. Here is the config

- PDC-60B scsi card reader connected internally to IB103 on ID 5

- external SCSI CD ROM (Toshiba XM-5401B aka XM-5401 TA) connected to IB103 centronics connection on rear of the sample on ID 3. This is physically terminated with a passive centronics terminator.

Akai settings:

- in the HDSK menu the following is configured:
"SCSI Drive ID = X" (normally set to 5 for the card reader, but i change it to 3 to read the cdrom)
"S1100 SCSI ID = 6"

When I adjust SCSI Drive ID to 3 the CDROM disc starts spinning and it's activity LED flashes but I get the error "Device is not ready"

The CDROM works fine with my EMU Ultra sampler on any ID I choose and can read the media I burned to test with. I've checked the pin options on the CDROM drive and the only things I can choose to play around with are the Mode Select pins: "PRTY" (not sure what that is), PRV/ALW, TEST, and TERM..

I'm still fiddling with it but any suggestions would be wonderful!

Just to be certain it wasn't a conflict with the PCD60B card reader or the CDROM enclosure I tested it by disconnecting the card reader and connecting the CDROM directly to the internal scsi header and power.. still errors... I get "hard disk read error" or "bad directory".. When ever I hit "load" the cdrom light flashes so it appears the sampler is trying to read something...
so this may be a compatibility problem? except XM5401 drives are listed as compatible on most places I've seen
or there is an issue with the media itself.. is there anything 'special' that needs to be done to burn an akai CD? i just used an ISO of an akai CD and burned it with gburner..

both of these problems seem quite odd.. and i don't think it's a problem with the media because my other sampler can access/load the data just fine from the CDROM.

OK - so apparently it was a problem with the way i was burning the ISO. i had to make sure that the burning software was set in a specific way.. something that gburner doesn't allow.

now everything is working nicely :D

hello,have you got a termination block on the end of the scsi cable,I remember that been important.also look into the formating type of the cds used,Im clutching at straws for you,keep me posted if you find a solution, have an s1100 too but havent done anything with it yet,and some of the add on modules.

is the other sampler an akai one?if so then there shouldnt be a problem loading data.
I dont know what other equipment you have got and what your experience is.These samplers can only read 16bit,they cannot read 24 32 and all the rest.I am trying to remember this stuff myself.Is the id of the scsi changable?moving pins and stuf or those little rocker switches?You need to have the scsi id match the scsi identity for the drive on the scsi id via the akai sampler,you probably already  know this but just voicing off in the hope it might trigger some line of thought/solution

Thanks for your replies. You may have missed it but I posted the solution which turned out to be the way the AKAI sample cd was being burned with my burning software. I have been using SCSI sampler devices for years so I am pretty confident I can get through any SCSI problem, which was why this one was a tricky one. I didn't think that the burning rate and block size need to be set to specific values to get the CD to be read by the S1100.

It's working now and I'm happy. Although the S1100 is a little touchy about reading the discs.. If the drive isn't spinning up just right, or you go too fast switching through partitions/banks I get read errors... but I just give it some time and it reads the discs when it's read ;) Figures for something that is 20+ years old at this point!
