Really that easy to upgrade?
 

So I got the new 120 gb drive to replace my Hughes DVR2 35 hour drive.

Went through the Hinsdale step by step and all seems well. Cloned the
old one and replaced it.

I'm just wondering how the Tivo knows that it has many more hours of
free space? There was no tweaking of software, just the hardware.

Did I miss something or is it really that easy?

If you used the Hindsdale script, then you ran either mfsadd or
mfsbackup with some command line switches that tweaked the software on
the harddrive (expanding the MFS partition) so TiVo would know about
and use the extra space.

Did you check the system information screen? It should tell you how many
hours are available.

There _was_ tweaking of software.

You had to run tools in the process when copying from the old drive to the
new drive.

The software which runs on the TiVo is designed to be able to
determine the total capacity of the MFS filesystem. It computes the
number-of-hours estimate based on the size of the MFS media region,
which is made up of several separate partitions on the hard drive.
This happens automatically every time the system is booted.

The Hinsdale-described upgrade process (using the Tiger software)
copies the existing partitions to the new hard drive, and then creates
a pair of new partitions which fill the remainder of the space on the
(larger) hard drive, and updates the MFS filesystem administrative
information to link in this new storage area.

So, when you boot the system with the new hard drive, the MFS
filesystem's media area is much larger, and the TiVo software computes
the new recording-time estimate automatically during startup.

What it boils down to, is that the folks who have designed this
third-party upgrading process have figured out (via some very skilled
reverse engineering) how to take advantage of some of the
flexibilities which are designed into the TiVo software.

I didn't have the script to use when I added my 120g. No, it wasn't hard
even then.

I just took my time, made sure my backup was good. I spent more time
plugging the drives into my PC than anything.
