Adding a new old drive to Unraid 6.4.1

[Bydgoszcz]

I've read that preclear is pretty much unsupported now and I've also seen discussions that Unraid will 'preclear' a disk in the background when adding it to the array.

 

With that being said how do I know if it is clearing or if there is errors? I've added the drive to the array and Unraid has formatted it but thats all that seems to have happened? Am I missing something? or is the best option to just run the extended SMART report?

 

If I'm beating a dead horse let me know.

It will look like a parity check, only there will be a blue icon next to the disk while it's being cleared, and the progress mentions clearing.

You can only format the drive after it's been cleared, assuming you have parity installed.

It's always good to run an extended SMART test (or a parity check) after, since clearing only involves writes, not reads.
