If I use UBCD to diagnose the "bad" drive, which version should I use? Windows or Linux? Does it matter to the drive being diagnosed? I don't want to take a chance on the diagnosing software to write something to the "bad" drive that would make it totally unusable in a TiVo.
When you boot with the UBCD cd, it loads from the cd and bypasses loading anything from the Windows drive altogether. Windows doesn't know the PC is on.
There will be a menu.
You choose hard drive.
There will be more menus.
You choose diagnostics.
There will be choices.
For the WD20EURS (which you should do the long test on before putting it into service just to be sure it's okay), you'll choose the newer version of the WD.
For the 1TB, after you've got it copied to the 2TB (in case it's fixing to go bad on you and quit), you choose according to what brand it is.
Those are non-destructive tests.
I've got someone else testing to see if a TCD652160 running version 11.0k of the TiVo software (the latest and probably last ever version for the S3 platform) can be "embiggened" onto a 2TB with just WinMFS, skipping having to use jmfs altogether.
In your case though, if that 1TB has limited life left, maybe letting jmfs "Xerox" it (with what I assume are 15 partitions as a result of the previous upgrade adding a 3rd MFS pair), and then add a single 16th Media partition to fill the rest of the space would be the best way to proceed, but only after the WD20 passes the long test, since the upgrade might be a one-shot deal, depending on the health of that 1TB.
