What is the size of the HDD spare area?

Question

Hard disks

I inherited a 1TB Seagate ST31000524AS drive. According to SMART, the disk worked for almost 5 years. The number of reassigned sectors is 3547, which SMART strongly swears at.
Does the manufacturer disclose data on the size of the reserve pool of sectors? Is it possible to calculate it from the specification data (there is no mention of the volume of the spare area)?
Persistent googling did not give any results, except for a critical mark of 3949 sectors.
Thank you.

Answer 1

If you need data - the disk is junk.
If not needed, continue to use until it goes to waste.
In both cases, the number of remaps and what will happen after them is purely academic interest.
The most detailed official doc does not contain such information: https://www.seagate.com/staticfiles/support/disc/m...
Probably not published at all. I remember 3000 remaps on a similar seagate, they took it under warranty without question.

Answer 2

Not the first year on Habré without an account, I decided to unsubscribe by the number of blocks, it coincided purely by chance that a friend just got such a nasty disk that he was all killed, there was no living place, we decided to leave the check for the night, or rather Remap broken blocks, and by the way, a fresh version Victoria 5.36, a 500Gb Samsung HD502HJ disk that was about 9-11 years old.
The disk was partitioned, as was usually the case for those years, exactly half, and the partition with OS Windows was not defined before at all, after a short work, the disk will most likely spoil itself (many times there were such cases with disks of this state) and later there are more blocks.
It was embarrassing that the broken sectors go in columns, through the same distance. It is clear that the disk is in a landfill, but this procedure helped - the system partition came to life for access to files and the number of reserve blocks exceeded all expectations; the program replaced 42704 blocks in 10 hours and 41 minutes.
HDD Tune shows even more bad blocks after restoration by Victoria, but nevertheless, access was restored and responsiveness was slightly increased.
