what does "comreset failed" for a damaged HD mean?

My hard drive is physically damaged, but I am seeing signs of life, and hope to revive it long enough to save the files. The computer is at least detecting a hard drive in the bay, but kept saying "comreset failed" during boot, before it gave up and booted from my external HD.

So, what exactly does "comreset failed" suggest for the possibility of reviving the drive myself so I can avoid taking it to a professional? Is there anything I can do to even temporarily help it read the drive? This isn't like the last hard drive I broke a few years ago, when the computer couldn't detect anything at all to read.

space permitting you should image the drive

ddrescue ( gddrescue is pkg name on debian based systems )
is the first thing you should reach for

that will image the failing drive
depending on how well that works you can recover files from the image

if the image is ideal you can map it with
kpartx -s -a -r -v /path/to/image.img
you can then mount the partitions that are newly created in /de/mapper/

if it is not an ideal image you can possibly recover files with
