HDR-FOX T2 HDD Replacement

Good point - remembered it only afterwards.

But then I did not think the source disk would actually be unreadable at the SATA interface level. The previous two HDDs I replaced had loads of errors but evidently they were remapped by the HDD controllers, since dd cloned them fine. I am surprised it is possible for an HDD to get hard errors; bad sectors are supposed to get remapped.

The owner was totally positive that the old recordings were not wanted.

Was the new disc smaller than the old one? That would fail to clone,
 
Same nominal size. But for dd clone of entire disc to work the new disc has to be the same or larger in actual sector count.
 
Do you think the new HDD was just over 1TB and this is also why the standard software could not format it?

I would expect dd to still finish OK if the destination HDD is bigger.
 
It makes an exact duplicate of an HDD.

I started using it to clone some win11 drives which had weird partition systems, which varied from one machine to another, and which even Clonezilla (which like almost all of these utilities is linux based) would not recognise. I don't use linux myself but dd is the best "dumb copy" tool I have ever used.

sudo fdisk -l (to get a list of drives)
sudo dd if=/dev/sda of=/dev/sdb bs=64k status=progress conv=fsync

fdisk output; one can see the new HDD is very slightly bigger. What I cannot tell is whether it is too large for the stock Humax to format.

One can see the three Humax partitions, plus (at the end of the listing) one called loop0 which one can google ("/dev/loop0 is a Linux virtual block device (loop device)" which is a mystery to me.

You know what... This forum is full of such kind helpful non-arrogant people. Along with so many, I just can't keep away from here.
 
You think? Isn't being unwilling to learn even when it's pointed out the very definition of "arrogance"? There is a pinned post in the HDR-FOX, HD-FOX, and CF sections "New Readers Start Here".
