Wasn't that 2048 bytes per physical sector, last time ? > Start? 163,840B > End? 167,772,160B > Error: The maximum head value is 254. > WTH? I didn't tell it heads, I think it takes the commas for a CHS addrss and the "772" for heads. See in https://www.gnu.org/software/parted/manual/html_node/unit.html the example (parted) unit chs print Disk geometry for /dev/hda: 0,0,0 - 14946,225,62 > So what sort of figures does it need to be happy?

It probably thinks of cylinders or maybe of the 32 MiB which fdisk reports as "optimal". > Looking at fdisks initial screen, it claims the physical sector is 4096? That's what parted says above. > I/O size (minimum/optimal): 4096 bytes / 33553920 bytes 32 MiB ? I wonder what kind of i/o that would be. 1 MiB as partition start is modern tradition and said to be ok for about everything. Have a nice day :) Thomas
