I just got a last minute request to do a HDVR2 repair this weekend when we visit the kids (short weekend and a long way to their house).
They have been having a lot of stops, reboots etc so it sounds like a bad drive.
I've been searching to get up to speed on the repair and only will have a day or so to get it right before the Super Bowl) and not a lot of time for retries.
Anyways, I've done 3 Tivo upgrades (S1, S2, Humax - All SA). Their machine was done as original HDVR2 with the add of a Weaknees drive (40 orig drive 1 + 120 new drive 2 for about 145 hours).
Can someone let me know if I the approaches below are right or wrong? (holes?)
1. Run diagnostics on the 2 drives . I have Powermax (assuming Maxtor) if the
drives are another brand, I'll need to look more.
2. Use DD or dd_rescue to copy the drive(s) to new drive(s)
3. Hopefully that will fix it. Is that approach good so far?
4. BUT if I have the covers off and drives are cheap.( They will most like be at least 120 gig each) It's tempting to expand to larger drives or perhaps reduce heat by reducing to 1 large drive. They want to keep the recordings if possible (longgggg copy times ;-( )
Can I copy/expand and preserve recordings?
Is it simple as a dd or mfsbackup/restore with a mfsadd?
OR Can I easily reduce from 2 drives to 1 larger drive (after adding the LBA48 kernel) AND not lose recordings? (I assume the PTV CD is the way to go)?
I assume I can't just dd the 40gig drive to a 200gig (example) and the 120 gig
to a 120 or 160? Or can I? (Ignoring for now the 137 limit and lba48 kernel)
Can I copy from the old drive with mfsbackup/restore and PRESERVE the recordings? The instructions I've seen seem to say you can't preserve the recordings but I've seen some entries that imply you might???
mfsbackup -Tao - /dev/hdX (/dev/hdY) | mfsrestore -s 127 -r 4 -xzpi - /dev/hdZ (/dev/hdZZ)
(drop the x for expand in this case?)
5. TivoWeb/ftp/telnet et al.... I assume the HDVR2 needs killhdinitrd to do this OR is it some other change?
then just copy the files over and setup the rc files etc.?
6. HMO / MRV --
a. via the patch? Is this just the original support (download only) and NO support for the newest Tivo-to-go (PC to Tivo) Goback?
b. If bi-directional Tivo-to-go is supported. How does the CSO/noscramble
change affect the transfers (i.e. if I can offload the recordings to my PC then can I upgrade to LBA48 (with/without scramble) and then upload the recordings? Thus getting around some of the complexity of multiple upgrades
(i.e. fix drive problem/upgrade size, enable MRV , offload recordings, upgrade kernel LBA48, resend recordings back to Tivo).
Sorry for all the questions. If someone can point out where I'm assuming too much or just wrong... I'd really appreciate it since I'm on a tight timeline. I'm still trying to get everything straight with more searching on here and other forums.
Thanks much!
