Because of : Win95, that slice is no longer truly a DOS partition in all respects. It *is* actually strictly in FreeBSD. I installed a 140Mb FreeBSD slice (40Mb root, 100Mb swap) alongside a 1.45Gb MSDOS partition. The MSDOS partition was version 6.2 and had *nothing* except the 3disk installed MSDOS. I booted FreeBSD, got this error & copied some files to the DOS disk. This resulted in corrupting not only the FreeBSD partition on that disk, but also a FreeBSD partition on a different disk on a different controller ! : I understand the FreeBSD team are working on the necessary adjustments : to allow FreeBSD to handle it correctly. Until then, I suggest you : forget writing to it from FreeBSD. I suspect that keeping your DOS partition sizes less than 512Mb will circumvent the problem - seems to for me .... but *DON'T* quote me on that ! This bug jumps up and seems to hit people for no reason ! If ya wanna experiment, do a backup first ! As Ken says, wait for the new & improved version :) -- Brian <brian@awfulhak.demon.co.uk> Don't _EVER_ lose your sense of humour....
