A1200 Hard Drive install

[amigakit]

You need HDInstTools from Aminet to prep,partition and format the hard disk first.  However because the HD is bigger than 4GB you will need IDEFIX if you have 3.0 ROMs and a suitable filesystem such as SmartFileSystem.

If you have 3.1 ROMs you will need NSDPatch, PatchStrip and SFS.

Drag and drop is the quickest or DOpus

BTW:  If you are using Kickstart 3.0 and use the normal FFS and make partitions over 4GB mark then data corruption will occur.

Hopefully you gave installed the patches I recommended and a better File System such as SmartFileSystem(SFS)
