WD Red WD20EFRX strange behavior.

constantly clicks, but all tests do not diagnose bad blocks, only the delays in the read operations. That shows me Victoria:

the strangeness is in the numbers 0, 256, 512, 768, 1024... and all other multiples of them
what's the problem?

There is nothing strange in those numbers. Victoria examines the disk in blocks of 256 sectors. This is the default setting and you can change it if you wish. If it finds delays in any of those 256 sectors within the block, it will mark the whole block as slow.

Do you need to recover data from the drive or do you want to just re-use the drive ?
I would replace the drive if data is not needed and apply the "slow fix" to attempt to recover the data,
The access to the sectors is .... slow.
If the OS itself is not playing tricks, like having a virus that slow stuff down, (you can test by scanning other drives) then your WD sure do have a probelm as it shouldn't be se slow to access it.

Information from the disk is not important to me, I need to re-use
It worked for 1 year in non stop mode, so small IMHO for this series
I tested it on other PC, the same behavior
It clicks even not connected with a SATA cable, I think it is trying to do remap
fix the problem flashing BIOS of hard disk? I saw there is Winbond 25 series, I have a programmer for this series. Really to find the firmware?

Bin the drive and buy a new one.
Regards.

Or sell it "as is" for parts.
