This isn't specific to EL5 though I'm sure folk here are interested. I'm subscribed to several lists, none ideal for this question.

I have Western Digital ATA drive that has a missing address marker.

A missing address marker is the sector 0 record, it comprised an address part and (almost certainly) no data, certainly no user data - that begins at sector 1.

I've asked a question of Western Digital and the response doesn't really answer the question.

Decades ago, when I was a sysprog for IBM mainframes, we used to run a special program that could be used to reformat part or all of the drive, and to assign alternate tracks. Typically, I'd try to reformat the track with the error, and if that failed I'd assign an alternate track.

There is, as far as I know, no problem with my data, but I would like to try a low-level format of the failed track(s).

Does anyone know of a program that can be used to do this?

Additionally, if anyone here knows how to convert an LBA address (bearing in mind this is a disk address, not a partition address) to a filename, I'm all eyes.

The good news here is that the partition table is a simple DOS style, all primaries.
The bad news is LVM2 is involved.

I've looked at the output of dumpe2fs, it would be helpful if it showed where in the drive the first filesystem block is, but it does no.
