I replaced a hdd in my freenas, but i have noticed that the disk is showing Deletes in Disk operations and Disk latency. The disk i replaced was a 7200rpm HGST 2TB 64m cache with a new WD blue 2TB 5400rpm 256m cache.(its blue i know, but it was 40$ new with warranty on newegg)
Before i replaced the drive i did a smartctl short and long, then the 3 pass badblocks on the drive followed by a long. could the drive be deleting the dummy test data?
Maybe this is an SMR disc, but i wouldnt think that WD would make a 2TB SMR. i looked online to try to find out if it is or is not.
The replacement went seamless, no problems what so ever.
Its just odd to me because the 5 discs i put into my freenas at first never reported any deletes.
can someone help me understand why this is?
