Ok, here's what I did. I see the sticky thread above which seems to represent my issue, but I'm going to describe what I did first so that hopefully someone can confirm I did everything right before I start burning new cds and trying something new.

Bought Seagate 160 gb disk.
Have Gateway tower computer, pentiumII, c drive running NT.
Drive intended for Sony SVR2000.

Ok, what I did was I opened the Gateway case, disconnected both existing drives (there were two, who knows what they do--it's not my computer) and the cdrom, and pulled all the IDE cables completely from the board. I set the cdrom to "slave" and reconnected it to the middle connector on one of the IDE cables. Then I connected the other end to the "primary ide" slot on the board.

I set the Seagate to "master" and connected it to the end slot of another ide cable, and then connected that cable to the "secondary ide" slot on the board.

I put the burned disk into the cdrom drive, booted up, and as the screens flew by, I saw that the Gateway was reporting that the ATAPI cdrom drive was set as "primary slave" and that it had detected a hard drive which was set as "secondary master." Got to the instantcake initial screen, confirming that I was installing instantcake for Sony SVR2000.

So far, so good, right?

I run through the instantcake process (one drive), no errors, and it finishes, telling me that my cake is baked and the drive now has a capacity of 174 hours and my next step was to power down and put the drive into the tivo. Done.

Once there, I turn it on, and it's stuck on "Welcome. Powering Up." 20 minutes later, still powering up.

I put the old drive back in and it moves from that screen within 10 seconds.

Have I done everything right so far? Should my next step be the suggestions in the stickied thread, or should I go back and do something differently?

Thanks in advance.

I reran the script, everything seemed to go perfectly. I scrolled up before I ran it, and sure enough, the CDROM is listed as hdb, and the target drive is listed as hdc. The Gateway says that the drive is in "LBA" mode.
