I have a 2 TB mechanical HDD in a 4 disk software RAID array which keeps showing "Disk is OK, one attribute failed in the past (41° C / 106° F)" and then getting ejected from the array. This has been going on a while now and everytime I add it back in to the array only to check a few weeks later and its gone again. Here are the disks in order a > d: ATA device, with non-removable media Model Number: ST2000DL003-9VT166 Serial Number: 5YCXXXT4 Firmware Revision: CC45 Transport: Serial, SATA Rev 3.0 ATA device, with non-removable media Model Number: ST2000DL003-9VT166 Serial Number: 6YXXXXPV Firmware Revision: CC32 Transport: Serial, SATA Rev 3.0 ATA device, with non-removable media Model Number: ST32000542AS Serial Number: 6XXXXXXN4 Firmware Revision: CC34 Transport: Serial ATA device, with non-removable media Model Number: WDC WD20EFRX-68AX9N0 Serial Number: WD-WMCXXXXX07 Firmware Revision: 80.00A80 Transport: Serial, SATA 1.0a, SATA II Extensions, SATA Rev 2.5, SATA Rev 2.6, SATA Rev 3.0 The second one down sdb keeps failing and is pretty old and notably the same type as sda. I would like to buy a replacement any advice on what to get ? I saw this one that looked reasonable: https://www.amazon.de/Blue-WD20EZRZ...coding=UTF8&psc=1&refRID=JWJ2WAMH0VGXQAV9V2S8 But a second, third, forth opinion would be great.
