CDTV+SCSI....=Problem :/

[bombermax]

Ok folks.
I have unnamed (made in 2010) SCSI controller for CDTV.
It comes with a Seagate 50pin drive http://stason.org/TULARC/pc/hard-dri...CSI2-FAST.html
I'm having problems, when copying/extracting files from CDTV CD to hard disk or even from disk to the same disk.
errors? - "I/O error", "cannot find file", "infinite loop" and many more anomalies. Mainly I've tried to instal ClassicWB, tried many methods, with help from budies from polish amiga board - no success. I'm damn sure that archives are ok. It breaks copy/extract action in the same place.... always..
Sometimes, when copying larger amount of files or bigger file suddenly CD is disappearing from the system (no object found error)... after that I need to eject CADY and pack it back inside... An yes, I've tried WB from 1.3 to 3.1 - no luck.


I was thinking about termination topic....
Is it possible that I don't made coorect?
As far as I know, contoller has it own terminator, diode, and fuse protection. If it comes for the hard drive, it's SCSI-II with own terminator. The jumper on the hard drive is set to take power for the terminator from the CDTV PSU, but i don't know, if the controller has it own power source for the terminator. On hard drive label a label is sticked with the jumper configs, I can choose from options:

" - Terminator power to the drive terminator and the SCSI bus- install jumpers on pins 21 and 23 and on pins 22 and 24 of J8. This is the default. - Terminator power to the drive terminators only-install a jumper on pins 23 and 24 of J8. - Terminator power from another device to the bus and the drive's terminator disabled-install a jumper on pins 21 and 23 of J8. - Terminator power to the bus only and the drive terminator disabled-install a jumper on pins 22 and 24 of J8."

But i fear that if I am to choose wrong setting, I can damage device/s

and what about the CDTV CDROM? And termination?

Can anyone assist me to resolve my problem?

My CDTV spec:

Original MC68000
1MB Chip ECS + 2MB FAST RAM
controller SCSI + Seagate
Kickstart 3.1
FDD.............

One more thing- WB works fine on the disk, playing black crypt, hired guns (install from a floppy disk) etc. also, when copying/extracting from floppy also..I get errors like this:

Do you have separate power supply for the drive? If not, perhaps CDTV's power supply is getting overload.

CDTV CDROM isn't SCSI so technically SCSI adapter or wrong termination shouldn't affect CDROM unless SCSI chip is damaged (they still use same DMA controller)

That's a good comment. I have power from the same PSU unit from CDTV. I'll try to connect drive to different PSU and let You know if it works.
Thanks

I've turned off floppy disk, tried to do the same operations as earlier - no success :/
