- Hello,I have some problems with old disks formatted with fdformat 1.8,
- if I have used the option "-x:2 -Y:3" which will give some sector
- sliding that results in faster access. Alas this access seems to be
- too smart for OS/2 as it won't read files from those disks without
- some "sector not found"-errors. Anyone having a solution for this
- problem?
- Another problem: if I used fdformat's ability to format a 720k-Disk
- on a 1.2Mb-Drive (which needed a resident program that fixed the
- double-step-flag in the BIOS-area), then these disks are also un-
- reachable under OS/2.
- If i can understand the latter problem I don't understand the first
- problem with sector sliding. Are those OS/2 disk-drivers (IBMFLP1.ADD
- by the way) that dumb, that they have to forfeit if they meet a slightly
- unusual disk layout?
- Can anyone please tell those guys at IBM responsible for OS/2 about
- this problem ? (As i know the same thing happens with disks formatted
- by VGACOPY a nice copy program from Germany which tries to optimze
- the speed of disk-access by using the sector slide scheme too).
