Intel 520 Series SSD failing?

aa17 — Sat, 19 Jul 2014 16:50:59 GMT

I am having some problems with my (Linux) machine and they might be related to the SSD. I ran smartctl to check the drives and some results worry me.

First the "power on hours" is over 900000. Second, the "uncorrectable error count" is over 135 million and rising. Is it an indication my drive is failing or is smartctl interpreting data wrong? Also, how can I test my SSD?

See below the complete output.

I understand your concern in regards of the SMART Attributes (09h/BBh).

Please refer to the following document for more information:

http://www.intel.com/support/ssdc/hpssd/sb/CS-034131.htm Intel® High Performance Solid-State Drives — Intel® Solid-State Drive Toolbox SMART Attributes FAQs

If by any chance you have a Windows* installed, you may test the drive with the https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=18455 Intel® SSD Toolbox.

Thank you for your answer. It turns out that the problem was with the RAM and not the SSD.

I have another question: in the above it says:

SMART Error Log not supported

SMART Self-test Log not supported

So when I run the self-tests I can't see the result. How do I run the self-tests (and see the results) in Linux?

I am sorry for my delayed response. I am afraid I am not a Linux* user but perhaps other community members will be able to help you. You may also try using the community of your Linux* distribution.

A late reply: Try "smartctl -x" instead of "-a".

The 520 and various other Intel SSDs do not support the old (not 48-bit LBA capable) SMART logs but the new ("extended") logs.

The Power-on Hours counter in the ATA Device Statstics log should report a reasonable value. See related entry on https://www.smartmontools.org/wiki/FAQ http://www.smartmontools.org/wiki/FAQ for a sample output.
