Today I attempted a backup just out of caution of a dual 250GB drive HR10-250 using the weaknees cd. This was my setup: [A]Primary Master Drive: TiVo A , stock 250GB Primary Slave Drive: CD Rom [C]Secondary Master Drive: Additional PC storage drive with Fat32 partition [D]Secondary Slave Drive: TiVo B (weaknees 250gb) All the drives were recognized correctly. At the weaknees# I entered: mkdir /mnt/dos mount /dev/hdc1 /mnt/dos Response"can't mount dos because it's already mounted." So I just entered: mfsbackup -f 9999 -6so /mnt/dos/tivo.bak /dev/hda /dev/hdd It scanned source drives and reported " source drive is 281 hours upgraded to 581 hours. Backup image will be 281 hours. Uncompressed backup size 1485 megabyetes. Backup size 1485 megabytes. Reported backup succesfull. My questions are: 1. Is that accurate about the source drive hours, etc.? 2. My tivo.bak file is listed at 216 mb on my hard drive. Is that normal? Thank you.
