how does hexedit change my boot record without sudo
 in all partition in tc user [without root permision]
example `hexedit /dev/sda6` and change NTLDR in to GRLDR in FAT16
 [and the old GRLDR file copy {grub4dos} boot correctly from sda6]

gerald_clark:
Sounds like you should not be using hexedit.

Lee:
Sounds like you should not be able to use hexedit for this purpose, as a non-root user.  I'd be curious to know the details about for every thing involved.

I've often mistakenly used the mount and umount commands w/o sudo and had them work.  This sort of thing is worrisome, though no biggie in my personal situation.  I've always chalked it up to some misconfiguration on my part - one of those things I'll look into some day.

Hi Lee
If the drive you wish to mount is listed in  /etc/fstab  and the fourth column (mount options) contains
the word  users , you don't need  sudo  to mount it, just  mount /mnt/sdb1  will suffice, as will
mount /dev/sdb1.
