Akai S1000 / S1100 samplers

Hi all,

I am trying to install internal HD into my s1100. I bought Conner
CFA540s scsi disk and data cable. Disk starts if I plug in only power
cable but if I plug data cable too then it doesn't power up.. and I am
sure that power cable was made correctly.. I also tried to set
different ids for disk but no success.. disk is terminated.
It looks like AKAI doesn't send power on p125 if disk is plugged to
scsi card (I checked with instrument). Is there anything else that I
should set up. I would understand that disk is not recognized or
something but it is realy strange that it doesn't get electricity..
Anyone had similar ploblems? All sugestions are welcome..

thanks,
Miha
