I have a two weeks old SSD (Kingston SSDnow 64GB). Yesterday, the computer shutdown twice and after rebooting I was bombarded with disk failure warnings.

I usually take such warnings serious (and backed up), but skeptical. After cooling down, the laptop boots again and the only red Smart value was the temperature (Ubuntu did not show the temperature of failure, but the at that time 29°). After refreshing the Smart status and doing a "self test", everything is green.

Before contacting Kingston support, I would like to know whether it could be due to a software issue:

  • Is it possible that it is false alarm, and how can I check?
  • I installed Ubuntu 12.04 32bit and took care of alignment. I supposed Ubuntu set up with optimal settings for SSDs, how can I check that there was no mistake?
  • The current temperature is around 40-56°. Is such a temperature abnormal for SSDs?

It does only seem to be temperature that's causing the issue here and here are a few things to mention:

  • The upper operational limit for this SSD appears to be 75°C.
  • SMART is reporting a threshold of just 30°C.
  • SMART can often be completely incorrect.
  • In my experience (with other brands of SSD) this is a fairly standard temperature.

That might sound like I'm saying it's all okay, but if it's pumping out errors, you might want to test it further. Sounds pathetic but I'd probably want to attach it to a Windows machine to see its SMART output there.

At least if it is only 180 hours old, you're almost certainly within the warranty :)
