Problem with SCSI drive not working on A500 hd8+

[countzero]

I'm trying to use an IBM 4.3 gb scsi drive (model DCAS-34330) with no succes. I'm trying to set this up on an A500+ with 2.04 roms, wb 2.1, using HDinstTools from aminet placed on wb 2.1 install disk. GVP A500hd8+ has 4.15 Roms I recently bought from TJlaser. Drive starts spinning during boot, but HDInstTools will not find the drive. I guess I'm doing something wrong with the jumper settings. I'ld be glad if someone can give me advice what jumpers to set on.

Available jumpers are :
1 Spare (50 pin) id bit 3 (for wide)
2 id bit 2
3 id bit 1
4 id bit 0
5 Disable auto spin
6 SCSI term on
7 disable unit attn
8 TI sync nego
9 auto start delay
10 delay start 6/12
11 disable parity
12 led out

The factory default scsi id of the hd is 6. I've tried with id bit 1, scsi term and disable parity (on and off). I have no idea what the 7 and 8 pins do. btw, I have two identical drives, and I tried with both.

Another question about the a500 hd8+, what does the jumper2 do on the hd8+ (it's under the rf shield, under the hd) ? and what is the factory setting ?

*bump*

I noticed something about the ICD trifecta drive at amiga-hardware.

"Please note, it does not support Western Digital or IBM hard drives"

does anybody know if the same thing goes for the gvp a500hd+ as well ?

Also, is there a way to check if the gvpscsi.device is properly loaded ? (with some kind of command or utility ?)

You specify the right driver when launching HDInstTools right? The program should be started from CLI/Shell with gvpsci.device as a parameter.

Oh no, never knew about that  :angry: I'll try this and the gvp install disk (if hdinsttools doesn't work) this monday and I guess I'll manage to solve this problem. Thanks everyone for the great information.
