HDDScan scan results

[FrederikSchack]

Hi,

I used HDDScan to scan a new 20TB WD Gold drive and a 1 year old 16TB WD Gold drive, but it seems like there is very limited knowledge about what to look for, except for clusters of slow reads?

I tried chatgpt and Google AIStudio, both of them seem to think that my results are unacceptable, but they can't provide any source for their tolerances.

On the new 20TB drive I have 2 red blocks above 500 ms and 133 orange blocks (150-500 ms). I know it means that it's probably running error correction routines and eventually is able to read the blocks. But how much is too much?

On the 16TB drive I didn't run a full test, but had more than 70.000 green blocks, 170+ orange blocks and a couple of red blocks before stopping the test and starting to copy the data from the drive. I did see large clusters of green blocks on this drive, sometimes with some orange blocks in them.

Hope somebody can bring some clarity to this

First, look at SMART.
Scanning HDD mounted in the system is a waste of time.
Well, at least from a bootable flash drive. And better not to mount it in the system. If your red blocks have LBA variables at each scan - this is OS interference.
And on the old HDD, recording was not always optimal (vibrations, temperature, etc.).

Show us the SMART attributes with Victoria.

There should be older English versions, too.

Ok, thank you, I'll try that Busy now, but I'll look at it.
