I just installed a MZHOU 2 SATA Expansion Card, PCI-E 3.0 GEN3 JMICRON + JMB582 Chip 

(https://www.amazon.ca/dp/B099ZCXJLQ?psc=1&ref=ppx_yo2ov_dt_b_product_details)

 

I then reinstalled a drive I had sitting on a shelf that used to be part of the array and the moment I spun up the server the drive has a SMART Error:

187 Reported uncorrect 0x0032094094000 Old age Always Never 6

I have not yet assigned this disk because of this error, I came straight to the forum. How serious is this? How can I tell if it the drive or the controller I just installed? 

 

I also have two other drives with the:

199 UDMA CRC error count 0x000a200200000 Old age Always Never 2

 

I have read that these are generally not a concern and are due to bad sata cables (my motherboard is approx 15 years old though), I have just changed both of those cables. 

 

SMART test on the dev1 drive has completed without error attched. I don't understand how that is possible since we know there is an error

That's not great, but since the SMART test passed the disk is OK for now, keep monitoring.

As long as the CRC errors don't keep increasing the problem is resolved.

 

Thanks. Sent you a small token for helping me out lately.

 

I will add this disk to the array and keep an eye out for new errors. The fact that the SMART passed OK means they were there before? They may have been....This drive has been pulled out of the array for over a year so I do not remember.

Thanks for the beer money!

Yes, it should have been.

Looks like the drive is part of the array now but after the pre-clear of the drive it is unmountable. How to fix this. If it is not fixable how can I remove this drive from the array and toss it?

 

This is a new array disk right? New disks added to the array need to be formatted before use, next to array stop button.

It used to be part of the array and I replaced it with a larger 6TB disk. Then I bought the SATA controller and added the disk back into the server. Added it to the array and Unraid began wiping it (took like 24 hrs). Once complete it shows as unmountable.

 

I thought the wiping of the disk was the same as formatting. I need to run the format?

Yes.

Nope. Wiping the disk writes all zeroes, removing any traces of files or filesystem formats. Think of a format as a filing cabinet with drawers and folders. It allows files to be stored in an organized fashion so they can be easily retrieved, as opposed to just tossing the files on the floor in an empty room. Filesystems take up space even when there aren't any files stored.
