Tivo HD upgrade...check my work? |
|
|
Tomorrow I plan to replace the 80-gig drive in my Tivo with a 160 hour one.
All I want to do is essentially copy the drive over onto the newer one, so
my program are preserved in the transfer, and I'll put the old drive away as
a backup.
I'm going to use the directions at http://tivo.upgrade-instructions.com/. My
Tivo is a standalone S2, 240080.
My questions:
1) Based on what I've read on the above site, I should be able to use the
MFSTools CD to simply copy the Tivo drive over to the new drive with the
following command:
mfsbackup -f 9999 -so - /dev/hda | mfsrestore -s 127 -xzpi - /dev/hdb
....this assumes that the old drive is on Primary Master (hda), the new drive
is on Primary Slave (hdb), and I'm booting off of CD (which will likely be
Secondary Master, or hdc).
Does that look right, and is it in fact true that the only two hard drives
that need to be in the system are the original Tivo drive and the would-be
replacement?
2) Assuming about 10 hours (at Basic compression levels) of data on the
original drive, how long can I expect this operation to take? I've heard
that someone did a 40-gig drive and it took six hours, and I have no clue
how full it was.
Thanks much for any help, once again!

Took me 3 hours to clone a three quarters full 120 Gig drive, likely a
function BOTH of how much is recording, and how many things are recorded. |

Looks about right ;)

Yes, and I would recommend unplugging any Windows formatted drives during
the process, just to avoid a SNAFU where the computer boots Windows with
the TiVo drives attached. In some cases, this can cause Windows to write a
signature to the TiVo drives that would make them unreadable by the TiVo.
(This doesn't always happen, and you can, from what I understand, recover
the drive with extra work, but it seems so much easier just to unplug the
Windows drives ;)

It takes a long time, and I'm pretty sure it doesn't matter how full the
drive is (or is that only with dd... I can't remember). Try to let it run
overnight, if possible.

Good advice, thank you, and I'm planning to do exactly this :) I'm lucky to
have one of those cases for my main PC where the drives all mount on little
slide-out trays, so basically all I need to do is mount up the Tivo drives
on the two trays I'm not using, slide out the Windows drives, and slide in
the new ones. Boot from the MFSTools CD (since the CD drives are already
installed and the system is known to boot from CD if I tell it to, and boom,
good to go. :)

Jack up there seemed to think it would only take a few hours, and my
original drive is both smaller and far less full than his is. (Ther'll be
maybe 10 programs on there.) But I'm prepared to leave the machine overnight
if that's what it takes, I can be online with this here laptop :) I just
want an idea of a time window so I know when to stop being patient and start
wondering if something went wrong. ;)
I appreciate the information, I think I'm ready to do this now! :) I'll let
folks know how it's going...

Well, it's underway, and unless things speed up once it gets past the part
of the drive with actual data on it, we're looking at a hair under ten hours
to transfer it all over, so it should be done in the middle of the night
sometime, and ready to go back in by morning. Which is fine, I actually
didn't have anything scheduled to record tonight, anyhow. So hopefully it'll
all work. :)

It's all done!
I figure the backup finished around 3:00a or so, when I got up at 4:30 I
checked it and it had finished, and I put the drive back into the Tivo and
put it all together and it fired up just as nice as you could want.
So now I have a nice phat 150-hour Tivo. Now they just need to get TivoToGo
out there so I can start burning DVDs. :)
Thanks to those who helped and gave advice! :)

It sounds like you weren't sure of the highest mfs id. I would have
used "-a" instead of the "-f 9999" to capture everything. I don't
know what the max possible id is. When I view my MFS System via
tivoweb, I see lots of elements with 6-digit ids.

Their directions don't appear to address installation of drives >137GB.
There are some additional steps you need to take if you want to be able to
use all of the space, and the CD image they link probably doesn't have the
necessary tools on it. This one does:
http://www.ptvupgrade.com/support/bigdisk/index.html
This link (included in the aforementioned page) also has some useful
reference info:
http://www.courtesan.com/tivo/bigdisk.html
In a nutshell, you need to replace the Linux kernel in your TiVo with one
that includes LBA48 support and you should enlarge the swap partition beyond
127 MB. (The stock kernel doesn't support larger swap partitions, but the
LBA48 kernel does.)

Nope, and thanks for the information. I'm good where I am, I think. Losing
23 gigs of space in the process doesn't kill me considering I paid $50 for
the drive. As it is it's highly unlikely that I'll ever fill 150 hours worth
of space, especially if I'm able to archive to DVD soon. From what I read,
it sounds like this method will cause problems the next time a software
update comes down the pike, too, and I REALLY don't want that. :)
