[clug] Re: cfdisk

[Rodney Peters]

Al,

The "subtle" way is called hacking.  Partitions on large disks are allocated 
in increments of about 7.8 MB.  So guess the size in MB then change units 
display to sectors.  If the number of sectors in the "new" partition does not 
match that of the lost partition then "delete" the "new" partition and try 
again with an amended number of MB.

cfdisk & parted may define "MB" differently.  Try to use what was originally 
used to partition the disk.
