>How do I give back the 1Gb partition to Windows? run the windows version of fdisk (FDISK.EXE ?) using win-fdisk, delete the 1Gb partition and in the free space create a new partition. Hopefully windows is clever enough to detect an unformated windows partition and offer to format it next time you reboot.
Otherwise, C:>format d: assuming that the partition that win-fdisk creates is assigned as d: next time you reboot. Disclaimer: It's a long time since I've done this sort of thing in windows. The above would have worked in ms-dos+windows 3.1 yuri
