This message is in MIME format. The first part should be readable text, while the remaining parts are likely unreadable without MIME-aware tools. --98048-834439379-1580767505=:14434 Content-Type: text/plain; charset="iso-8859-2" Content-Transfer-Encoding: quoted-printable probe.bin prints: Boot sector C=3D0x3D H=3D0x10 S=3D0x3G Press key 0x3G is a rather strange hex value... I assume off-by-one error while=20 doing 'A' + h. I looked at what fdisk on different systems prints about this 32MB CF=20 card. On Linux (fdisk -c=3Ddos /dev/sdX): cyls: 1024, heads: 1, sects: 61 On Linux (fdisk -c=3Ddos on FreeDOS image): cyls: 3, heads: 16, sects: 63 On FreeDOS (fdisk /info /tech): TC: 61 TH: 15 TS: 63 I've tried all of those values, with the same effect (....4!). Also I think the name of config option in kernel configuration is=20 misleading. Tracks refers to number of tracks per cylinder which is heads=20 * sectors. I assume what this option really expects is 'cylinders', and=20 IMO should be named that way. There's a chance that the problem with FDD is not with the drive itself.=20 I'm waiting for delivery of used 3.5'' 720k DD floppy disks to verify this = suspicion, should arrive in a week.
