Only 8GB of 20GB HDD showing in OS 3.9

[MarkWatson]

I recently got an A1200 again. I put an old 20GB 2.5" disk I had sitting around in. The plan being to turn it into a WHDload box and maybe other stuff...

I'm aware of the 4GB limit, so I initially just partitioned 4GB of my drive (512MB main and 3GB other). Then I installed OS3.9 and BBag 2 before trying to partition the rest. Unfortunately OS3.9 only show 8GB as being available. A total of 16382 cylinders.

I'm not aware of any 8GB limit, so presumably its just confused about my drive geometry. How can I change that? I don't want to blank the HDD since I have no CDROM and installed this via floppy and wireless ethernet...

Thanks,

Mark

P.S. I tried searching and didn't find the answer to this. If someone is going to post a "please search" reply, please put the keywords to search in;-) Of course I'll probably work them out immediately after I post this!

Thanks for the suggestions. No luck, yet though:(

scsi is version 43.43. I don't think there is an 8GB jumper on the disk. It does report as 18GB and I was using it all on the PC laptop before.

The HDtoolbox bug sounds most promising. I tried entering a number higher than 16382 into HDtoolbox when creating the new partition. It just goes straight back to 16382. Do I have to go "Install drive" and enter the details there? If I do that should I be able to put in the same partition details as my existing partitions? It warns it will delete everything. I don't want to wipe everything on the existing partitions.

Thanks,

Mark

Thanks, that did the trick. Though I broke it at first and didn't have HDToolbox for OS3.0+ around. Luckily I still had an OS2.04 install disk complete with HDToolbox. Phew...

Now I just need to sort out some large filesystems.

Thanks,

Mark

I think I originally set up the drive with the OS3.0 HDToolbox. The OS3.9  (from AmigaOS XL CD, which includes BB1) + BB2 version detects the correct settings if I use "Install Drive".

Interestingly when I broke it, I used OS2.04's HDToolbox to fix it. That detected the drive with the correct number of cylinders to give 18.6GB! Quite surprising for such an old version.

Thanks,
