The physical connector? Like this thing:
If it’s an issue with that you’d likely be able to straight up see it, bent or missing pin. Or check with a meter for shorts. And clean the pins I guess just in case they’re oxidized.
But this is wayyyyy down the list. Is the same LBA bad every scrub? Then it’s the drive, probably. If not did you check the cable (most likely culprit), the sata controller would be next most likely, then port, then solder joints (which you’d have to redo to replace that port anyway so moot point I guess). Udma crc errors?
If you do replace it you’d need to solder. I don’t know how to source that sata connector, that would be the hardest part. There is likely a part number on the actual sata port somewhere though it may not be visible until it’s removed (and even then it may not be available, may have been a custom part or it may be legacy at this point).
The soldering is actually not that tough though if you can find one. Add flux, add leaded solder, hot air, remove, wick to clean pads, fresh solder to pads, more flux, hot air new one on (second tricky part - patience with temp low enough to not melt plastic but enough to melt solder, can be a pain for connectors like that)
