Our faithful Sony SAT-T60 now boots up to the Green Screen of Death, after 7+ years of faithful service. I upgraded it to 2 160 GB drives myself years ago (kept the standard kernel), then later added a CacheCard, all of which were working fine until the GSOD starting appearing. I don't want to invest in new hard drives for it, since I can get a new HD DVR for the same price. But I would like to salvage any shows I can from it.
I'm following directions here and here but I'm getting stuck by a "Not a TiVo super block!" message when I run mfs_streams or mfs_info. (tivopart seemed to work: several partitions appeared on the KNOPPIX desktop for hdc and hdd.) I tried the 20050604 image of mfs-utils first, then the 20060503 image.
I'm pretty sure I disabled encryption the last time the software was auto-upgraded (after which I disconnected the phone line so I wouldn't have to keep re-hacking it) but I can't be positive (it was probably a couple years ago). I read about ciphercheck, but that appears to be for S2 units.
Am I doing something wrong? How likely is it that the system just too messed up to recover anything? Anything else I should try?
