Re: Partition Manager feedback
Posted: Wed Nov 09, 2022
I entered "50MB" in to IDETool as you requested. *free says 52,396,032 free, 32,768 used. I'm not sure how else to tell the "exact size" you're asking for.JonAbbott wrote: Wed Nov 09, 2022 Could you please confirm the exact size of "One" so I can figure out which words hold the partition size and offset to the next partition.
Well, as far as I'm aware, from what I remember, I'm "pretty sure" that's not likely to be the case. This is a "CloudDisc" CF card bought brand new from Amazon, put straight in this RiscPC and formatted with RISC OS 4's HForm to E+ format. And that's it. I'm "pretty sure" I did no other buggering about with any other HForm or partitioning before putting it in here. 2.91GB would be a completely bizarre size to pick anyway. Either way, PartMgr's not really showing the live reality of what the drive's doing in the machineJonAbbott wrote: Wed Nov 09, 2022A debug log will probably explain what you're seeing, but if I was to guess:So I suspect you have an MBR that's mismatched with the contents of the drive.
- the drive was initially formatted with an HForm that writes a MBR partition table
- the MBR partition table has a 2.91GB partition entry that isn't the "official" Acorn type
- the drive was later reformatted as "16GB" with a formatter that doesn't clear or update the MBR
