Install Workbench on CF card problems

[alexh]

Does anyone know what these values should be?

IDE devices (which are ATA5 or lower) have a command set with an 8-bit "sector count" field.
SCSI devices (which are SCSI10) have a command set with a 16-bit "sector count" field.

A sector has been defined (until recently) as 512 bytes.

By setting the MAX TRANSFER to a value of "0x1FE00" (255 * 512) prevents the scsi.device for IDE interfaces from creating malformed IDE commands.

While IDE commands support 8-bit sector counts, not all devices like them. Windows (and other operating systems) tend to transfer data using 128 sector commands. By setting your max transfer to "0xFE00" (127 * 512) you pretty much guarantee "sector count" compatibility with any IDE device.

One more thing Sim. When you install the card in your HD8+, test it with copying a disk to your CF card. For example your Workbench disk.
Like you said, the errors appear at random. So it's probably best to copy a large bunch of files to your CF card.
I changed my maxtransfer at least 20 times, and every time I copied my WB install disks I got (random) errors on the CF card.

Yes, you can change it after partitioning and installing WB.
 
Good luck.

From where can I change the MaxTransfer and Mask values after workbench is installed?

Open your Workbench partition then the Tools drawer. Run HDToolBox and change the values from in there.

When I change these values it does not allow me to "Save Changes to Drive" and when I enter again to change these two values I get the original 0xfffffe and 0xffffff again. I am afraid these are not being saved.

I have set the hardrive to allow both read/write operations.

Something else,

At the moment when I connect the CF card to the GVP HD8+ I first get a black screen for a long time and then the insert disk screen. Could this be related with the SCSI_DEVICE_NAME or the MASK value of the partitions?

When you change something in the maxtransfer and mask fields, you have to press ENTER for the changes to be accepted.

When you use HDtoolbox on your real amiga, the SCSI_DEVICE_NAME tooltype should be 'gvpscsi.device'.
Try to boot from your 3.1 install floppy, and start hdtoolbox (with the correct scsi_device_name).
Does it recognize the CF card then?

no problems with sandisk CF IV did not change any settings.

I formatted the CF card again and I plugged it in the GVP. I then Insert workbench install disk and change the SCSI_DEVICE_NAME to 'gvpscsi.device'.

However when I open HDToolBox I have all the buttons disabled again. I guess this means that the GVP is not recognising the CF card (or that there is anything connected to it).

Does the MASK value effect this? (However there is not way to change the MASK value of a formatted CF card if HDToolBox does not even want to see it connected right!?)

Doublecheck if you connected things the right way. Maybe you forgot to connect the powercables to your SCSI-IDE adapter (I know it's a long shot, but you never know).
 
Does your HD8+ have it's own PSU, or did you perform the PSU mod, so it is powered by the same PSU that powers the A500? If so, maybe the PSU of the A500 doesn't provide enough juice to power both the A500 and the GVP.

Everything should be connected right. The IDE -> CF adapter card has a right light turning on. This would not turn on unless properly connected with the SCSI -> IDE card.

No the GVP has its own power supply. When I try to autoboot I can see the GVP trying to access the drive without any luck.

I was wondering if maybe it is a Jumper setting on the SCSI -> IDE card.

Do you have a manual of the SCSI-IDE adapter?
 
If you have a spare IDE harddisk, you can try to connect it to the SCSI-IDE, and see if that works.

No it did not arrive with a manual. I am trying to contact the seller to see if he has any knowledge about how the Jumper settings should be set!

Yes I was going to try and test each part of hardware by it's own. Like that I'll know if each peace of hardware works fine or not.

[MozzerFan]

What CF-IDE and SCSI-IDE adapter are you using?
Do you have some links to the sites where you bought them?
 
Edit: Never mind. I found an old post of yours.

[MozzerFan]

I have found a PDF with the jumper settings of your SCS-IDE.
