Akai S1000 / S1100 samplers

Hi! Dear friends:


I have a problem with an AKAI S1100 sampler and do not know the cause. Well, I think the problem is in the SCSI system but not sure.

I tried first with an MO drive, set to ID 5 and S1100 in ID 6. When I inserted the disc it starts to turn but soon stops and the sampler does not detected it "Disk drive not ready ..." MO drive is apparently in good condition and with the terminator position.

Later I tried connecting to the internal SCSI connection IB 103 a HD  installed in a ITX pc case with power supply. Surprise! The HD works if I just plug the power wire , if I connect the SCSI ribbon cable does not turn, and of course is not detected by the sampler "waiting for hard disk ..." 
The HD has the ID properly configured and the terminator position.

I read on this web http://akaiscsifaq.digidude.net/ about terminator fuse, I checked the fuse and is in good condition. However I'll try to change it to see the results.

I'm starting to get a little desperate.

Thanks and sorry for used a google traslator, I'm from Spain
