More details on the drives: SATA, WD Red(tm), NASware(tm) 3.0Īs per request, here is the output from hdparm and smartctl. Why is it exactly 3TB instead of 4? Seems too exact somehow. Is it likely to be the HDD controller, the motherboard/bios (MSI/AMI), or something else? I put the drive in a different machine, and the BIOS there also reports 3TB. I will replace the disk, but was wondering if anyone had seen this before and If there is a fix.

The only change I made recently is to update the OS (on a drive outside of the RAID). This disk has been in the server for several months with no problem.

The sticker on the physical disk says 4TB, just like the other 3. I noticed that the OS was reporting one of the disks to be 3TB, so I rebooted and checked in the BIOS and it also reports 3TB. I have a server with a software RAID system.
