Thanks for the help, Hugo.
Sorry that it has taken me so long to get back to you. My router definitively
died just after I sent my email, and I only had a slightly Heath Robinsonian
replacement up and running OK about 45 minutes ago.

Probably - I was trying to get backup bang up to date before blitzing the
media with tests after a strange hanging boot up. :-(

There were none the same, but a lot like so:
Aug 29 17:38:42 Dozy kernel: ide: failed opcode was: unknown
Aug 29 17:38:42 Dozy kernel: end_request: I/O error, dev hdb, sector 76183415
Aug 29 17:38:42 Dozy kernel: hdb: dma_intr: status=0x51 { DriveReady
SeekComplete Error }
Aug 29 17:38:42 Dozy kernel: hdb: dma_intr: error=0x40 { UncorrectableError },
LBAsect=76183416, sector=76183415
Aug 29 17:38:42 Dozy kernel: ide: failed opcode was: unknown
I read those together as probably the HDD which has the OS and /home, and aim
to start there in my tests. (Since it seems to be reading that is the
problem, and reading a specific location at that.) But am open to
correction.
TIA
