Help please...

...I'm trying to keep all my shows.

The new blank drive is exactly the same 3TB WD purple, just 5 years newer...

Since the target is the same size as the source, why not try ddrescue (or dd_rescue; I forget which is on the 'MFSTools CD image' and which does exactly what so you'll have to GOOGLE that...)?

Set the parameters for one pass (don't beat too hard on the source HDD) and see what happens.

Good Luck!

Help please.
I am trying to backup my failing 3TB drive out of a Roamio...

...In your case, just clone the drive via hardware dock or software sine the drives are the same size.

A cloning dock may 'hang' on any bad sectors (according to my readings)...

 

[ClearToLand]

Depends. But I have to agree I have had more hangs than successes. Certainly it is easier to do and does not tie up a computer...

Doesn't everyone own at least a half dozen desktops along with a couple of laptops?

My latest kit build, the Altair-Duino:

Not RasPi-related, I know, (RasPi-adjacent?) but since it's now sitting with my PiDP-8 and PiDP-11, I figured I'd post the photos here.

Unlike the PDP kits, the Arduino Due is pre-programmed with the Altair 8800 simulator, so there's no underlying OS (i.e., Linux). Thus I can't use it for double-duty like running a Pi-Hole or RetroPi anything like that. Still, blinkenlights!

Well I have 2 laptops and a PDP-11. But I don't recommend the PDP-11.

...I don't really have a PDP-11. At work it used to be my "desktop" until it was retired.

Have you seen @windracer 's hobby?

...If using ddrescue is this the right string? : ddrescue -f -n /dev/[baddrive] /dev/[gooddrive] /root/recovery.log

Try using this GOOGLE Search: ddrescue jmbach site:tivocommunity.com

It will point you to (from Jan 28, 2017):

I believe I used the following when I recovered the Windows drive I mentioned.

ddrescue -d -f -r3 /dev/sda /dev/sdb /media/PNY_usb/rescue.logfile

Note that if you are booting from a CD that you'll need to use a USB flash drive if you want to keep the log file or try to use it for further attempts at recovery (which I did not do).

I was using information from the following 2 webpages.

Guide to Using DDRescue to Recover Data - Technibble

How to Clone Hard Disks with ddrescue | Datarecovery.com

I did use the SystemRescueCD mentioned in the second site but I'm pretty sure that I used the command from the first site.

Read the two included LINKs and DO NOT USE "-r3".

...What software would you recommend if not using the dock? Windows software doesnt recognize the Tivo drives...

I don't understand why folks insist on using Windows when troubleshooting TiVo HDDs. At the very least use Linux...

...ddrescue for Linux
HDD Raw Copy Tool for Windows...

Were those two lines supposed to be LINKs?
