Akai S1000 / S1100 samplers

After a couple of weeks documenting and researching me into the ends of the network, I managed to install on PC a PCI SCSI controller brand model Tekram DC-395U, (the same type that the Adaptec 2940 PCI I arrived and did not work, so I could be fried or comes fried ....) 

I did it with a Plextor CD-ROM reader that chained with a 4.3GB hard drive and 512 blocks / sector in the PC, all connected to the internal connection of the controller. The controller is connected to the sampler with a Centronics adapter cable 50 - SCSI II 50, so I tried a bridge because the hard drive and the CDROM into the internal SCSI card sampler not recognized, always launch error "Hard Disk not ready "I even thought I had breack it ... But a strange thing 'cuase external connection works.

I managed to load samples from the CDROM (monsters the ZERO-G!)

But I still have the problem of hard disk. Is empty, not formatted and when I select it in the sampler continuously read the error "HARD DISK ERROR. " I tried to format with the same sampler and an infinite "HARD DISK FORMATIING ... Waiting ..." for 8 hours. I know that the sampler will not read or do anything beyond 512 mg, but seeing this post I understand that
Is not formatted to 512 mg and stops, but remains "caught"?
What AKAI format program I can give, if that program exists? Or should I format it in DOS?

The PC detects the sampler and displayed on-device manager as <| SCSI Optical Device> but only when I select the SCSI ID of the sampler CD-ROM, if I select the hard disk ID and refresh the Adm. Device disappears. Regardless, both the disk as the CDROM and the controller are fixed in place Adm. XP devices.
