gray squirrel Posted November 22, 2019 Share Posted November 22, 2019 (edited) I am trying to diagnose some sata errors. I have a EP2C602-4L/D16 motherboard with 2 SSD's 2 HDD. non of my hard drives are generating any SMART errors, my guess is one of the ports is having issues, I have no idea why something is defaulting to SATA 1 speeds? it doesn't look like I have a port labeled 14, although this board has 14 ports. i have seen suggestions that this is a doggy cable? it is intermittent and happens 1 or 2 times an hour.

Squid Posted November 22, 2019 Share Posted November 22, 2019 I would first try reseating the cabling to the drive and at the mobo. SATA connectors aren't exactly famous for making a good connection Quote Link to comment
gray squirrel Posted November 22, 2019 Author Share Posted November 22, 2019 but what drive? I don't have at Sata 1 devices attached. this is my guess as its suggesting a 1.5 Gbps link Quote Link to comment
Squid Posted November 22, 2019 Share Posted November 22, 2019 From the Main Tab, if you click on the hard drive icon next to the model it will bring up the error log for the drive, and then it'll be pretty obvious which one. One caveat though is that you may disturb other drive(s) cabling in the process of reseating the one thats needed, so you may / should do them all. Quote Link to comment
gray squirrel Posted November 22, 2019 Author Share Posted November 22, 2019 (edited) non of the drives are showing any errors. and non of the drives relate to ata14.. i have taken the array off-line and unplugged and re-pluged all the drives Edited November 22, 2019 by gray squirrel Quote Link to comment
JorgeB Posted November 23, 2019 Share Posted November 23, 2019 That is part of the Marvell controller, it's a virtual device, normal and nothing to worry about, just don't use those 4 ports (1st 4 white ports) for devices as they are a known problem on those boards and tend to drop drives.

gray squirrel Posted November 23, 2019 Author Share Posted November 23, 2019 this makes sense as i was looking at the logs and there was a line saying ata14 was a virtual device I have disabled the Marvell controller, lets see if that helps Quote Link to comment
