It does.
I gave up with that disk after using an new partition or an extended
partition freshly created in NT. Found out after experimentation that
wd0{a,b,c,d,e,f,g,....} refer only to the active partition. Is there any way
of bypassing this instead of fdisk -a? If you'd like the disklabel for
partition 1 just email... I'll have to recreate the partition but thats no
prob.
I then chucked in a spare drive and used the whole thing rather than trying
to hit the second partition, and formatted as fresh FAT from NT.
From NetBSD-current, the FAT drive would no load at all. An fdisk revealed
the active partition was partition 4; changed this to 0 and saved data. Then
looked at disklabel. This showed nonsense (its gone now but easy to recreate)
so I hacked the partition definitons appropriately and the drive now happily
mounts as msdos and everything is fine.
However, NT obviously is responsible for this disk info or there are some
probs in the code. I suggest this is reviewed as every time I have used FAT
disks, I have had to hack disklabel stuff........may not be NetBSD issue,
rather inconsistant DOS,Win,NT,ME formatting,fdisking I don't know.
