Yeah, something is not quite right here...
The card was put back into the A1200. The pfsformat returns an "Initializing disk..." message and then nothing. It should have finished in a few seconds. I can still move my mouse cursor but cannot open any volumes. Like the whole IDE bus just locked up. Here is the command I entered:
pfsformat drive DH1: name "Work" quick noicons fnsize=107
I even tried to do the DOS Format within the HDInstTools program. It too locked up.
I know my CF card is okay as it works great in WinUAE and it came from another A1200 using a different adapter. It was prepped in OS 3.9 before.
I think I will try finding another one of the same adapters.
