I suffered the disappearance of my 6TB Seagate on my H3 a few months ago. The old/original H3 was replaced without fixing that, but an older EHD from my 612 days worked fine on the "new" H3. So I decided there was something amiss with my 6TB Seagate and I attempted to repair it. I successfully did rebuild an EHD with a bad partition on my 722, but alas I had no luck this morning on this Seagate.
First I tried to boot up Alma Linux on this computer. Kernel panic! Boo hiss on new hardware requirements of the latest Linux distributions. So I fell back to Scientific Linux 7.9 and that booted up fine. There were 13 ext3 partitions on the Seagate. The first was 1GB and presumably contains encryption keys and possibly an index to the 12 500GB partitions. All partitions were healthy except for the 3rd, which would not mount. I tried fsck and there was a lot of repairs going on but it still wouldn't mount. So I tried a Gnome tool and that didn't work either.
So I gave up on that partition and reformatted it with the same volume ID as the other 500GB partitions, which is "Linux filesystem". That made all partitions mountable using Linux. Back on the "new" H3 and it is again AWOL. I tried unplugging it (no pop-up) and plugging it back in again and it wanted to format the disk. I said "No" to that. From noises, I know that something has been going on for the last hour, but still the disk will not show up. The only thing I can think of doing is deleting the partition and seeing if it will work with 11 500GB paritions, all of which so far as I can tell, are still good and still contain hundreds of programs.
Any other ideas?
