Do I need a new SSD?

Post by fpeelo »

Hi

I think my SSD may be wearing out, could you tell me how to diagnose it, whether it needs replacing, and what exactly are my options for replacement?

The PC is a FITLET2-CJ3455 S/N 1181129-02568 bought Jan 2019. But I had a previous Fitlet2 that I couldn't get it to work reliably and replaced it-- so I am not sure that the SSD comes from 2019, it may have been from the previous machine. It's running Linux Mint 19.1 with all updates installed.

Yesterday the printer started having problems, CUPS wasn't able to write to the print queue. Then I wasn't able to save a file, and I found that the SSD partition had become read-only. I tried rebooting and fsck said there were unexpected problems... but it was getting late so I powered it down and went to bed so I could look at it when more awake.

Today I installed smartmontools. It gave some info, which I tried to understand with the aid of web searches. The output is below for reference. I note:
  • Device is: Not in smartctl database -- so there are some attributes that might be useful but cannot be interpreted
  • Warning! SMART ATA Error Log Structure error: invalid SMART checksum. -- could that be the result of not being in the database? Or does it mean something is going wrong?
  • No self-tests have been logged. [To run self-tests, use: smartctl -t]
The lack of self-test info could be down to the log not being readable. From my web searches it seems that smartctl should be able to test the drive without it having to be unmounted, so I tried

Code: Select all

sudo smartctl -t short /dev/sda
It said the test would take about a minute... after a minute the computer locked for a few seconds, and then the drive was read-only again. In dmesg there was a lot of this:

Code: Select all

I rebooted...

So now I think I need a new SSD, or is this a software problem?

it seems M.2 SATA 2280 SSDs can be bought locally but 2260 and 2242 are much harder to find.

If I need a new SSD, what can I use? On https://fit-iot.com/web/products/fitlet2/ I see M.2 SATA, 2.5″ HDD/SSD and eMMC on an M.2 module are options, so I guess PCIe (NVMe) is right out, yes? I have not used eMMC, if I get one of those do I just partition and use it like any other hard drive, and is it cheaper because it is slower, or because it won't last as long?

If the SSD is wearing out, can I get it going again by partitioning off the affected

On
http://www.fit-pc.com/wiki/index.php?ti ... 2_SATA_SSD
there's talk of some SSDs not working because pins used for eMMC are interfering with what the manufacturer wanted to use them for; it links to

http://www.fit-pc.com/wiki/index.php?ti ... _/_Airtop3
which goes to
https://docs.google.com/spreadsheets/d/ ... sp=sharing
which doesn't list very many suitable SSDs. Has the list grown since that was published? Apparently there is a FACET card to allow 2280 SSDs to be used; can I run a 2280 SSD in the machine, maybe with the top off, until such a FACET would arrive in the post? Or can/should I boot off a USB drive? (might be the cheapest/most convenient option - if it works).

For reference, here is the output of sudo smartctl -i -a /dev/sda

Hello
First of all fitlet2 does not support NVMe storage. It can be either SATA M.2 SSD or SATA 2.5" HDD.
You are right regarding the size, 2280 is supported by using one of the appropriate FACET cards (like FC-PCI: http://www.fit-pc.com/wiki/index.php?ti ... FACET_Card). By default this device supports 2242 or 2260 only.
You can try to use meanwhile the external USB disk and if you for sure wish to replace your current SSD with a new 2280 one, order the FACET:
