My weaknees S2-SA bracket kit comes in Thursday so I've been putting together a plan for my upgrade, and I just wanted to post it here for review.. if I'm doing something incorrectly or you would recommend doing something else please let me know. Thanks! TiVo - Humax T800 80hr S2 SA Upgrade - Western Digital Caviar SE 320GB Ultra ATA/100 8mb ($125!!) Power off, pop the hood, disconnect IDE cables and take out TiVo original drive. Connect the original TiVo drive to a PC (no pre-existing HD's, just 1 CD-ROM) as primary master, 320GB new drive as primary slave (jumpering apropriately). Boot with MSFTools 2.0 CD w/ large kernel, check drive sizes, make sure all displays ok, and when it does.. mfsadd -r4 -x /dev/hda /dev/hdb verify new recording size/time.. put original drive back in TiVo, add the new drive to the bracket and put in TiVo.. cable up... and that's it! am I missing anything?
