Hard disk won't work after changing case

[jggimi]

You are correct, you would use # disklabel -E sd0 to start the disklabel editor.

Thank you, by the way, for reviewing the man page.

1. Use the "a" command to add a new partition.
2. Select a partition letter. You may use anything from a-p except for c, since that is the physical drive.
3. Since you have told us that this is a FAT filesystem, even though it is an NTFS partition, use "msdos" as the partition type.
4. The starting sector number is 63.
5. The editor should show the remaining sectors of the drive as the default, press the ENTER key to accept the default. You can also use an asterisk, *, to specify the remaining sectors of the drive. If you need to, you can type out the number of sectors manually, which if my math is correct, is 3907023940.
6. Use the "w" command to write the revised disklabel to the drive.
7. You may then use the "q" command to quit.

You may then attempt to mount the partition.
