After you transferred with with ddrescue - you then need to use winmfs to make the additional space available  basically - when your using ddresscue your only copying the existing partitions the extra space isnt used on the drive yet.  If you still have your recordings intact run Winmfs, then choose Tools->MfsSupersize->On now you will get the additional space. You shouldnt need to do anything else no guided setup, or kickstart 57.

Hi - yes, all the recordings appeared to be intact following cloning with ddrescue, but the additional space wasn't being recognised. I figured I needed to do something using Winmfs to address this, but unfortunately seems like I chose the wrong action in restoring from the truncated backup I had taken and selecting to used the additional space - rather than using the Supersize tool as you say.

 

Looks like I have no option but to run ddrescue again to get my recordings back on to the big drive, then run MfsSupersize. Would you say that is correct?

 

Thanks.

I would check your existing recordings on the device anyway if they are there try and play one - but I would expect them to be gone to be honest so yes you might need to use ddrescue again then use Tools-> Mfsadd followed by Tools-> MfsSupersize in winmfs.

Make sure you do this actually after ddrescue:
Tools-> MfsAdd

 

Tools-> MfsSupersize

 

If youve already done MfsSupersize - it doesnt matter just repeat with MfsAdd and then again with MfsSupersize.

Ran ddrescue again, which took approx. 14.5hrs and seemed to work OK. Hooked the drive up to the Tivo to see what I've got and now I'm getting the Welcome screen, followed by the green screen announcing serious problem, then the Almost There screen, which keep cycling around, though not necessarily in that order every time. Don't know whether it will eventually boot, or if it's in a loop?

 

Before I hooked the drive up I had tried to run Winmfs to add the drive's extra capacity but ran into a problem with the Winmfs GUI shutting down, with the message below. Everything had gone so well with getting my Tivos upgraded, but I feel like I'm going down a rabbit-hole with this now!

How much data did ddrescue recover as a percentage?

You could try a kickstart code specifically 57 which appears to make it do a file system check.

 

1. As the DVR restarts, all four LED lights on the front bezel of the DVR will be on at the same time.

 

2. As soon as all four go out, immediately (within 2 seconds) press and hold down the PAUSE button on the remote. (If you are unable to catch the timing, you may also hold the PAUSE button down continuously during the restart until only the yellow light comes on.)

 

3. When the yellow light comes on, release the PAUSE button and then press 57 from the list below on the remote control. (You will have approximately 10 seconds to do this.)

As mentioned previously I'm happy to check the original drive for you and try and copy across its contents at no charge - would need the Tivo for a couple of days then if its not possible to restore we can bring it back to factory defaults without recordings.

Thanks - am at work but apparently it still hasn't booted after approx. 4 hrs. So I guess I'll just power it down when I get home and try what you suggest.

ddrescue appeared to copy everything across to the new drive. Screen shot below from when it finished.

Am just not seeing the sequence of LEDS that you mention above - most I saw was 3 - green, yellow and red - a few minutes after powering on. Was difficult to pick when to do things, so as you suggested I held pause through the power up process, releasing after briefly seeing the yellow come on, then input 57. No change though - it just seems to be in a loop. I disconnected the drive and connected it to my laptop and had another try with Winmfs - selecting the drive showed it as "Tivo 2 or 3" with 1TB capacity, though when I tried mfsadd I got the message "Not a Tivo drive".

 

I connected the original 320GB drive back up to the Tivo and it booted up normally and all of my recorded stuff is still intact. So my issue seems to be that I have a new 1TB drive which doesn't want to play. I'm guessing that the drive is not faulty as the first time I ran ddrescue to copy my original drive to it, it worked OK on the Tivo, just didn't see the additional space - I then stuffed up by restoring to it from the truncated backup of the original drive. Since then things have just got worse. Would it be worth formatting the new drive by some means, then running ddrescue again?

seen you still have a working 320GB drive why don't you just do the whole thing from the start again using winmfs?

First thing I tried was copying to the new drive using winmfs, but it stopped about two-thirds of the way through. Tried 4 x times with same result. Hence, following advice from @rphenix, used ddrescue to do the copy.

I read somewhere - either on geekzone or oztivo - about using a WD utility to write zeros to a drive to clear any issues. I have downloaded their Data Lifeguard and am currently running the Extended Test. I see there is also an Erase function - the thing that writes zeros? - worth a shot?

Dr Tivo offers this advice to write zeroes as mandatory.
