HD Installation Problems

[Oldsmobile_Mike]

Your problem is going to be if you want to use the full capacity of the 18.6GB of available space.  3.1 doesn't support drives that large by default (you'll generally be limited to about 4GB).  There's various methods of hacking and patching 3.1 to use large capacity drives, which vary pretty widely depending on controller, file system, version of the operating system, etc.  It's not hard and instructions exist all over the forums (just a google search away!).

My personal opinion is to use 3.9 instead, but an easier method, if you just want something simple, might be to get a CF card and just reinstall 3.1 fresh.  OS disks and CF adapters are dirt-cheap and will save you a lot of headache.

Thanks for the info guys, I've managed to get WB3.1 loaded and running but still on the PC. Next step is Amiga 1200 surgery. I guess my next headache will be getting software ported from PC to Amiga once the HD is fitted.

Lots of options for this, too.  Various serial & parallel transfer methods, adding a USB solution to the 1200, probably the easiest (IMHO) would be a Fat95-formatted CF card with adapter in the PCMCIA slot.  Have fun!

What file system? Didn't you read my comment above about not using more than 4gb with 3.1?
