I found myself with a defunct notebook computer containing a 5GB hard disc (formatted Fat32 under windows 98SE).
I found a USB 1.1/2.0 external disc housing (for about 12 pounds stering, which I though was pretty nifty). It can takes power from the USB wire, when using USB 1.1 connection (theres a switch on the case).
Therefore I extracted hard disc (IBM Travelstar), placed in housing, set switch to 1.1 and attached to PSR 3k.
Recognised instantly as a 5 Gig drive. All the files and drives present (from the Win98 installation on the PC) were visible. I used the "Function / Utility / USB Device / Initialiase" function to reformat the drive.
No worries.
So everything seems wonderful now... except the hard disc housing is only suitable for thin (7mm thick) drives, wheras the one I'm using is 12mm think so the housing doesn't re-assemble properly!
So now I'm scouting around for a thin portable hard disc. But at least I am now totally confident that this will work.
I though you all should know!
The hard disc case is an "Argosy HD 522". I think this is no longer in production, but the Argosy USA web site is here:
