Partition an 8GB CF in ClassicWB: No devices found

[remotenemesis]

I've also posed this over in project.ClassicWB but this might be more familiar to somebody here:

I've setup a basic ClassicWB ADVSP install running on macOS in FS-UAE which I'd like to copy over to an 8GB CF.

Everyone has rw permission on the device.

I started out with no file-system on the disk (thanks to gparted on a linux install). A disk icon for the CF shows up Workbench but MyFiles:Install/LargeHD/HDInstTools shows no drives whatsoever.

I was able to Quick Format the disk with FFS and I later installed SFS, neither of caused any devices to appear in HDInstTools.

Am I approaching this correctly?

You must tell HDInstTools to use uaehf.device

Aha, thank you! Some progress but now showing as unsupported.

If you can format the CF card before you even created a partition, then there's something wrong. You probably added the card to UAE as a super-floppy rather than a real HDD.

In order to let UAE recognise a harddrive as a real harddrive, you have to set the values for Surfaces, Sectors and Reserved to 0. In WinUAE there is a button "RDB mode" which does this. I have no idea how it's done in FS-UAE.

I have RDB (maybe) set this way:



hard_drive_2 = /dev/disk2
hard_drive_2_type = rdb

I used this:

to make my 8GB and 16GB CF cards. Saved me a lot of time. Maybe it will help you.

Thanks for taking the time to post this. I don't have a Windows machine, so I'm trying to get this working on macOS or Linux.


I did make a little progress (maybe) by using rdbtool to partition the drive. However it looks like it only supports OFS and FFS. I ended up with 4 partitions of 800 or so MB when trying to partition an 8GB drive.

Hi!

Did you check permissions of /dev/disk2?
It must be read-/writable for your normal user, which isn't the default.
To find out, type the following line in the terminal:
ls -lA /dev/disk2

Alternatively, you have to run fs-uae as root, which I don't recommend.
Also ensure that your AmigaOS is working properly with >=4GB devices (device driver and filesystem driver).

I did.

I can try running FS-UAE as root. However, ClassicWB can access the disk but not format to 8GB...hmmmm...

Sorry, must have overlooked it. Did you actually test it with a simple dd command like:
dd if=/dev/disk2 of=/path/to/your/home/disk2.img bs=512 count=1

/path/to/your/home/disk2.img should have the first 512 bytes of your disk.

Did you check AmigaOS compatibility with >= 4GB drives? You'll need both a compatible file system and device driver.

Also try the following (while FS-UAE is not running):
echo 'RDSK' | dd of=/dev/disk2 bs=4 count=1 conv=nocreat,notrunc

This will write the RDSK identifier to the drive. Maybe it helps your partitioning program to recognize it properly.
