Why does CrystalDiskInfo see my dying HDD as good?

This report from Backblaze (8 years ago) says that error 187 is a reliable predictor of failure.

The same report was already quoted in post #1.

oops! It does seem odd that there seems to be no recent news on this aspect.

My PC just failed to boot into Windows. Linux is now running from the HDD in question.
I have a backup of the BCD file.

All HDDs get some uncorrectable errors but things like CHKDSK mark those sections as such and OS knows not to write to them.

Do you mean the disk will mark the "uncorrectable errors" sectors as unusable, and Windows will not write data onto those unusable sections?

0xc0000185 = I/O device error

In the forums we see drives with excellent HD Sentinel / Crystal Disk scores that have failed.

The scoring methods are proprietary.

The above tests are primarily based on SMART which attempts to predict drive failure.

How do I interpret SMART diagnostic utilities results? | Support Seagate US



Drives that had been exposed to power outages may display excellent smart and may have failed using long generic or long drive self test.

To best assess the status of a disk drive please use what Dell, HP, Lenovo, etc. use in their hardware diagnostics for warranty replacement:
Long or short DST.
