I found the following post on another site. My PC is all SATA on the motherboard. I was able to mount my CDROM using "sde1". When I got to the last step (restore...), it would not recognize my new target harddrive. I tried sda, sdb, sdc, sdd, etc. Any ideas on how to transfer the 00001 IC image from the thumb drive to the HD would be appreciated. Here's the post I tried to follow: "This post details the steps I used to make a new TIVO drive using a computer with only SATA (no IDE). First, unzip the ISO. I use Winzip. After downloading the .zip, unzip and you'll have another "zipped" file with the extension .ISO. Unzip that one and you'll see the files and folders. Copy the InstantCake image to a flash/thumbdrive. Put it in the root of the thumbdrive for ease (but you can have other stuff on the drive). The image is found in your InstantCake files under /_images. It's the really big 000001 file. Go over to mfslive.org and download their mfslive ISO (you'll need to register on their forum to access this file). Burn the mfslive ISO to a cd. I use CyberLink Power2Go and chose the option "Burn disk image." Set up the computer on which you'll be doing your work. Turn the computer off first and unplug the power cable. Then, unplug the computer's hard drive and plug in the new TIVO SATA drive. Make sure your BIOS is set up to boot to cdrom. Start the computer with the MFSLIVE cd in the cdrom drive. After it finishes scrolling through all of the details about your computer, use SHIFT-PAGE UP/DOWN to locate the place where it assigned your new TIVO hard drive a sd* designation. Mine was sda. Plug your USB thumbdrive in and you'll see the Linux system assign that drive a sd* designation. Here was the trick for me - my thumbdrive was sdb but I had to point to the first partition to mount it. Mount the thumbdrive. I used this code: mount -t vfat /dev/sdb1 /dos Check that you can see your 00001 file by typing cd /dos and then ls. Use the following command to transfer the InstantCake from the thumbdrive to your new TIVO drive: restore -s 128 -xzpi /dos/00001 /dev/sda (<-or whatever your sd* is)"
