kaypro iv/10 disks? They look like they're 10 sector (numbered 0x0a -
0x13), rate=2 disks.
Sure that isn't 5K before failure?
Notice that side "B" of a disk formatted by Kaypro does NOT have the
correct value for "head number" in the sector headers. With a PC (NEC765
type chip), you will have to go below the BIOS (Int13h) for reading those
sectors. It is not very hard to do, but can introduce some additional
fun, particularly with relatively new machines.
I'll probably mount the 5.25" DSDD drive in
my linux box as well, but
it'd be nice to know how to read disks without hassle :)
TRY formatting the disk IN KAYPRO FORMAT on the PC. The good news (what
little there is) is that the Kaypro (WD type chip) although it puts the
wrong value for "head number" in the sector headers, does not object to
finding the correct value there.
