I give up.... I have a hacked RCA DVR80 with a 300G drive hacked with the Zipper, tytools, HMO, MRV, etc. All was working great for a many months, then it started to reboot every few days. I read that "mfsassert -please" would force a GSOD and start a scandisk-ish function on the hard drive, and tried it. After the GSOD completer (3 hours) the UNLEASHED (Almost there...) screen came up and there it sat.
Pulled the drive and ran PowerMax which reported no errors.
Put it in a PC and can mount the /dev/da4 partition fine. I copied a backup copy of my rc.sysinit.author file to the etc/rc.d directory and tivoapp into the tvbin directory. Still no change.
I noticed that the VAR directory totally empty, so I put the log dir back and put some old log files in it in case it was hanging while trying to write to missing logs. Still no luck.
WHere do I go from here? Can I mount the MFS partitions and copy shows to a fat drive to make sure i do not lose them? FYI: I have a fat drive in the PC that I used to copy the backups to the TiVo drive.
