A little help, please? I'm having a problem doing the sfdisk. It gives me this error: BLKRRPART: Invalid argument OK Warning: start=63 - this looks like a partition rather than the entire disk. Using fdisk on it is probably meaningless. (Use the --force option if you really want this.) (Edit) Looks like someone else just had the same problem, heh. In any case, I am using sfdisk, but it keeps telling me that "fdisk" part. Also, tried umount again, and it's telling me that's also invalid.
