Per title, trying to remove a 4TB drive from the array, move a 10TB parity into the array and replace the 10TB with a 14TB. However, when I start the 'copy' procedure, I get the following errors in the logs:

sdh is the new 14TB drive. I have stopped the copy and restored the array as before and am running a preclear on the new drive, but should I be worried the new drive is already bad? Additionally, when I opened the case and swapped out the 4TB for the 14TB, on restarting the array I got this error on the 10TB drive:

 

Warning [UNRAID] - udma crc error count is 2

 

Just want to make sure I don't have any drives that are about to fail before I swap them over...

Actually I said I'd try by preclearing the drive, but I get those same blk_update_request: I/O error messages when I try that and, when I try to unmount the drive, I get the following error:
