December 23, 20178 yr Recently, I got an alert that I had a failed disk, and that is was disabled. Since the drive was fairly new (under 6 months) I thought this was odd, and did an extended SMART test which showed no errors. I removed the drive and put it in another PC and checked, and it was fine there also. Anyway, to be cautious, I replaced the drive with a brand new 3Tb NAS drive and rebuilt it from parity. Within a few days, this drive is now showing that its failed, and was disabled. Both disks pass all tests without issue, so I'm now suspecting a cabling issue. I use an LSI SAS controller for all of my drives, and wonder if anyone else has experienced any cable issues with the SFF-8087 to 4 x SATA cables? Or do you think it could be something else? A bad power connector maybe?
