Thanks everyone ....The nice man at Amiga kit sorted me outHave you selected install the the hard drive? After this, you need to read the drives configuration & from that, you should get to see all the partition space on the drive when you go back into the HDToolbox program from the re-boot. On this visit, select Partition Hard Drive & the whole 30+ GB should be showing.
If this still fails, try HDInsTool from Aminet & if still no joy, be sure OS3.9 is patched with both BB's.
If still no go, you could have a really bad hard drive & it could be worth trying another if you can't run a pee-cee hard drive diagnostics program on it.
