Question Some basic MFSTools questions about different boot CD's.

I'm gearing up for another Tivo upgrade and in doing my research I've come across a few different Linux commands for accomplishing the same task. Seems like a good opportunity to educate myself.

All commands assume upgrading a single drive Series 2 DirecTivo to a larger single drive with the following:
hda - Windows 98 C: drive.
hdb - new large upgrade drive.
hdc - Original TiVo drive
hdd - cd-rom/cd-rw drive

#1 Using the Hinsdale How-To instructions and the free PTV LBA48 boot CD, the following commands should be used to identify the C drive:
mkdir /mnt/dos
mount /dev/hda1 /mnt/dos


Using the Weaknees Tivo Upgrade Instructions and their LBA boot CD you identify the C drive by using:
mount /dev/hda1 /mnt

I assume the way the CD's are set up determines which method is correct. Is one any better than the other? More efficient or otherwise?

#2 Using the Hinsdale and PTV, the following commands save a backup file to the C drive:
mfsbackup -f 9999 -6so /mnt/dos/tivo.bak /dev/hdc

Using the Weaknees:
mfsbackup -f 9999 -1so /mnt/backup.bak /dev/hdc

What's the difference between "-6so" and "-1so"??

#3 Using Hinsdale and PTV to copy all your recordings to the new LARGER upgrade drive:
mfsbackup -Tao - /dev/hdc | mfsrestore -s 127 -xzpi - /dev/hdb

Using Weakneeds to do the same:
mfsbackup -Tao - /dev/hdc | mfsrestore -s 127 -r 4 -xzpi - /dev/hdb

What does the additional command "-r 4" get you? Why use it?

Thanks for educating me!

#1 both mount commands will work with both CD's just the location (directory) of the mount point

#2 5 Changes the compression levels 6 results in a slightly smaller file

#3 the -r 4 Sets the cluster size need for large drives.

Descriptions of these and other options see http://www.tivocommunity.com/tivo-v...7&&#post2651877
