[NBLUG/talk] [Fwd: extended partition does not start at a cylinder boundary]

[Ian Sutherland]

No takers on this one? I am trying to delete a NTFS partition in Fedora
2. Because the partition does not end on cylinder boundary, I cannot use
Parted to remove it.

Thanks, Ian

I have created a problem that I do not know how to fix, "extended
partition does not start at a cylinder boundary". Help.

[root at localhost sbin]# sfdisk -l /dev/hdd

For this listing I'll assume that geometry.
