A4k SCSI->IDE->CF project (problems)
« on: March 17, 2010, 08:26:18 PM »
Hi all,
I've recently started a project to replace the old and rather limited in capacity SCSI HDD on my A4000 with a CF card. The project called for 2 conversion steps: 1) SCSI->IDE and 2) IDE->CF adaptor.

First of all, my config:
Cyberstorm 060 MK2 with SCSI module and 128MB RAM
Deneb USB
PiccoloSD64 gfx card
Indivision scandoubler

The SCSI->IDE adapter I got myself is the R-IDSC-E/R, from eBay. I connected a 20GB WD IDE disk on it and everything worked perfectly. I transferred my data from the SCSI disk to that with no problems and successfully replaced it altogether afterwards.

I connected the CF card (a Sandisk Extreme III 8GB) to an external USB card reader (using the Deneb card) and partitioned it with HDToolbox, formatted it to FFS and copied all my data once again over there.

The problem I've been having is when trying to use the IDE->CF adaptor on top of the SCSI-IDE one. The system starts but doesn't boot (not even Early Startup Menu) with the HDD led staying on continuously (as if it was a jumper issue on the HD). The IDE-CF adaptor has it's jumper set on "Master".

I've tried setting the jumper to Slave, whereas the system starts but fails to find any disk and displays the Kickstart "insert disk" screen.

I've tried checking the jumpers on the SCSI-IDE adapter, but everything seems fine there and no tests I've tried helped the situation (for example disabling DMA mode and enabling PIO). With the exact same jumper settings, the HD works normally anyway (instead of the CF adapter with a CF card).

Arggg... I can't think of anything else to try! The adapter itself shouldn't be an issue, as CF cards are basically IDE devices, right?

Anyone with any suggestions? Any at all?

@Tension: I can't really, the SCSI->IDE adapter only has one port. So it's either Master or Slave on that port and I have no second SCSI->IDE adapter to attach another device.

Still, I doubt that would be the issue, since as I mentioned above the configuration works if there's a HDD attached (jumper as single, WD drives are a bit strange about jumper configs - single, master, slave). The problem only occurs with the IDE->CF adapter and a CF card on it.

Thanks for the reply.

I will try to test the system with another IDE to CF adapter then, preferably a Addonics one. Unfortunately it costs about 20 times the price I got the first one... :-P
