Hard Drive Fried! How to downgrade
(Click here to view the original thread with full colors/images)

Posted by: whino

I originally bought my Tivo srv-2000 that had a 30gb Quantum hard drive installed in it. I then upgraded the Tivo with a second 80gb western digital drive. Tivo worked fine for a year, and then just lask week it started looping thru the "Powering up…" and "Almost there…a few more seconds please." screens. I then went to http://www.weaknees.com/tivo_powering_up.html and found out the most common cause of this problem was that a hard drive is fried - and to test if the hard drive is fried I should Maxtor's Powermax. The original Quantum hard drive was fine but the Western Digital hard drive was making an odd sound and Powermax didn't even recognize the hard drive....So I have determined that the new Western Digital hard drive is fried..So I removed the new Western Digital hard drive from Tivo and booted it up with just the original Quantum and it continued to loop through the "Powering up…" and "Almost there…a few more seconds please." screens. I think it continues to loop because Tivo is expecting the Western Digital drive as well.

Now my question - How do I "downgrade" my original quantum Tivo hard drive to enable it to boot by itself in the tivo without the western digital drive?

I think I might need a virgin image of a tivo srv-2000? If so, where can I download/get one?

Thanks

There's no way to recover from that without a backup. All backups are 'virgin' in this context - a compressed backup reverses any upgrades (but you need a working drive set to make one).

OK I found a virgin image from a ftp site- here is the info from the info file:

-------------------------------------------------------------------------------------
Sony SVR2000 Backup

30GB, 11-partition image, version 1.3

Virgin Drive, made before even powering up. I have tested and verified the restoration to several drives already.

Files:
SVR2000.bak 843,025,683 bytes

Used mfstool 1.0 to make the image, booting from Kazymyr's 2.6i BootCD.
"mfstool backup -6so /mnt/dos/SVR2000.bak /dev/hdc" (no quotes).
---------------------------------------------------------------------------------------

I have a dual boot with linux and win2k installed on my machine. What is the linux command to extract the SVR2000.bak to the Tivo 30gb quamtum hard drive (assuming the quantum hard drive is setup as slave and SVR2000.bak is on the master hard drive)?

Also, is there anyway to backup the previous shows I have recorded on tivo to my master hard drive, extract the virgin image, and then copy the previously recorded shows back to the Tivo Quantum hard drive?

Also, I assume that once the 1.3 image is extract, Tivo will upgrade the software to the latest once I dial up?

Thanks

Wow, that image is huge (800+mb)! My DirecTivo images are like 129mb. Best of luck with the FTP! :eek:

Also, you might want to give your old drives another look. If you can get your computer to see that WD you might be able to salvage you Season Passes...I do NOT believe you can salvage anything off your original A drive because it is married to your possibly fried B drive. But as long as it still healthy it can receive your new image and continue on as if it were fresh out of the box. However, you also might want to consider throwing a new 120gig drive in there to maintain the capacity you have become accustomed to! You can even restore and expand with one command! Hinsdale really has made it too easy

Be careful NOT to boot into Win2k with your Tivo drives attached to your computer. You should not need to boot into Win2k anyway to do the restore, but just keep that in mind.

I assume you are familiar with Hinsdale's Upgrade instructions? Look here for the upgrade instructions:
Hinsdale's How-to Tivo upgrade

Excerpt:

quote:
Restore Mfs Tools backup image to your new large upgrade drive using ONE of the following commands:

(This is assuming you have connected your new large upgrade drive as Primary Slave)

Note: Remove the "-s 127" from the following command line if restoring image to the original TiVo A drive (otherwise the image will not fit) or if restoring a Series 2 80hr image or TCD230040 image (reported that these units have not functioned with increased swap)

Here's what you'll most likely have to do assuming that your destination drive is on Primary Slave and the compressed image in on Primary Master. Note: I do NOT have a standalone and have never upgraded one. Please check Hinsdale to make sure that these commands fit your situation before doing this!

mkdir /mnt/dos
mount /dev/hda1 /mnt/dos
mfsrestore -zpi /mnt/dos/SVR2000.bak /dev/hdb

Finally you can unmount your drives using the following command:
umount -f -a -r (umount not unmount)
Ctrl+Alt+ Del

Finished!

You can adapt the command to fit your scenario:
hda = Primary Master
hdb = Primary Slave
hdc = Secondary Master
hdd = Secondary Slave]
