Hi! > Boot sector unreadable, disk not yet formatted.
You can skip that check by explicitly requesting a not undoable formatting, see FORMAT /? and use /U or better /Q /U for quick unconditional format. > Cannot find existing format - Not saving UNFORMAT data.

As you say /D made no difference, did /D display useful extra details? D for debug mode, that is. If I understand you correctly, you tried to make tha partition FAT32 in FDISK? Have you checked if it worked by looking at the FDISK status after a reboot? > format version is 0.91w > Same results with format d: /d This version is the first which uses OpenWatcom C, can you check whether FORMAT 0.91v works better? > If I do the same with a bigger virtual HD (ca. 550 MB size) fdisk > creates a FAT32 partition and format has NO problems. > I tried both two times. > > Any ideas? Is it reproducable? As said, please compare FORMAT 0.91v here. You should also ask WHICHFAT D: to see which partition type the DOS kernel wants for D: or you could even check whether using a non-FreeDOS kernel makes a difference for you.
