[SOLVED] SSD keeps dissapearing

[t9i2]

Hi,

I have a Dell Optiplex 7010 with an Intel 256GB SSD, 500GB HDD and DVD-RW drives.
Since today, sometimes comes the Bluescreen in Windows 10, and than the SSD (with the OS) is gone, not visible from BIOS either.
If I turn of the PC and back again, the SSD works fine, Windows boots. Also tried to switch the SATA port. The drive shows to be healthy.
Happend 3 times in the last 5 hours, without any heavy usage.
I read, that the PSU could be bad, but my SSD and HDD are on the same power cable. Could be the PSU and the SSDs are more sensible or a SSD?

Have a nice day,
Toni.

Please do this tests to check if your assumptions are true:

• Check the S.M.A.R.T. values for SSD and HDD. Post the result here. Software you can use: HDTune, CrystalDiskInfo (please change from hex to decimal before copying as it is easier to read)
• Check the 12V when stress testing. You can use OCCT for stress testing and look for a time/voltage graph (and please make sure the option "12V" is checked)

If this is a SATA drive, replace the SATA power and data cables.

Hi,

also tried with different sata and power cables.
Did not see any voltage problems. Should I try a firmware update?
Here are the test results:

HD Tune is too general in order to get any usable information from the ssd. Try to find a tool from the manufacturer instead to get a proper reading.
