You need to turn on advanced package view and update the package list, or just install it from the command line:

Code:
humax# opkg update && opkg install hdparm

Excellent, so it should be possible to force a sector repair with the following. Please be careful to get the sector number exactly right.

Code:
humax# /mod/sbin/hdparm --repair-sector 410253531 --yes-i-know-what-i-am-doing /dev/sda

I've had a quick read up and the syntax looks OK. All I can offer are the obvious: is there a /dev/sda and is it writable?
Thanks - any review is helpful. The output shows that the command ran for over 7 seconds which implies it did properly seek through the disk towards the bad block but for some reason it couldn't write to it.
Apparently there are errors which cause dd to fail but hdparm --repair-sector should work as it performs the operation directly on the disk.

By the way, I did have advanced packages turned on from about 2 years ago si I don't know what went wrong that it does not show hdparm in available. I installed it via cli. maybe it's firmware 2.15?
Code:
humax# /mod/sbin/hdparm --repair-sector 410253531 --yes-i-know-what-i-am-doing /
dev/sda
 
/dev/sda:
re-writing sector 410253531: succeeded

How do the SMART attributes look now?

197 Current_Pending_Sector -O--C- 1 100 100 000 Old_age Always -
198 Offline_Uncorrectable ----C- 1 100 100 000 Old_age Offline -

and do you get any errors from the Humax disk check now?

HDD test pass

Pheeeew. I shall start mentioning you in my night prayers. :)
Did this error mean that my HDD is on its way out?

Looking good - the disk should be fine now. At least, the sector that was bad is fixed, it remains to be seen (from the Humax disk test) whether there are any more.

Hard disk test via on-screen Humax menus. Last time you got error code 8. Hopefully it will pass this time.

Probably not. A bad sector is going to occur from time to time - it's just that these AV/CE disks seem to handle it particularly badly. The most useful thing that will indicate a disk on the way out is a rapidly rising reallocated sector count in that table of parameters.

Ok, so my disk exhibits the same problem again. Hard disk test results in this

No.

Do I need to run fix disk in maintenance?
