I have a Series 3 HD (The "652" model). A year or two ago, I replaced the internal drive with a 1TB using the instructions on this forum and WinMFS. Everything worked perfectly. Several weeks ago, due (I suspect) to sudden power loss to the device, the TiVo started acting weird - shows would freeze and stutter when I was watching them (and/or during recording), sometimes forcing the device to reboot suddenly. I suspected that the drive was either damage or merely corrupted and in need of a reformatting. So today I took apart my TiVo and connected the drive to my Windows PC. However, in order for Windows to run a disk check, I was forced to initialize the drive, which created an MBR table. This apparently screwed up the TiVo partitioning, and I hadn't thought to use WinMFS to create a backup first. So now WinMFS says my drive isn't a valid TiVo drive, and the TiVo won't boot. If I'm reading the original "how to upgrade your TiVo" thread correctly, all I need is the "Truncated Backup" (.tbk) file appropriate for my model, so I can use WinMFS to set up my "new" drive (Essentially I want to do what is in showthread.php?t=370784#instructions from steps 16 on, treating my existing drive as if it were the "new" drive.) Does anyone know where I can download one (a .tbk file for my model), or does anyone have such a file sitting around? I can provide a place to upload it to if necessary. I don't care that my settings and season passes are gone; I can fix all of that easily enough. Before anyone suggests it, I am looking to spend precisely $0 on recovery disks, new drives, new drives pre-loaded with software, etc, etc. If various disk check and repair utilities (and / or a complete reformatting) don't fix the drive, I'll have the manufacturer replace it - it is still under warranty. Thanks.
