  • This issue is happening on my custom-built desktop. Relevant specs:
    • Motherboard: ASUS P8Z68-V PRO
    • Utilizing Intel RST technology (application that uses unused SSD as cache)
    • Processor: Intel core i7-2600k (not overclocked)
    • HDDs: RAID1 of 2x Seagate Barracuda 1TB (ST31000524AS) (RAID performed via z68 chipset)

Machine has run fine for ~1 year with no issues, and has been well-maintained (dust, etc.)

What Happened

  • Random Freezing issues -- intermittent
  • Looked at the RST application screen to see that the acceleration cache was listed as "unavailable" -- recommended that I power down and reconnect the drive.
  • Reconnected the drive to no avail.
  • Attempted to move the drive to another SATA port. Acceleration option disappeared from RST software.

Now, the freeze happens whenever loading something particularly data-driven (a video, a game, etc.)

Steps Attempted

  • Reconnected the drive to no avail.
  • Updated Intel RST software to v. to see if that made a difference.
  • Attempted to move the drive to another SATA port. Acceleration option disappeared from RST software.
  • Connected the drive as its own volume. Formatted it, ran disk check errors -- all seems fine.
  • Reconnected the drive and selected it again as the cache drive.

Now, what happens when there is a freeze:

  • Machine freezes
  • I am unable to perform any command
  • Screen then goes black
  • I hit the reset button
  • During boot, all drives show as "Disabled" and I am told no volume can be found
  • I then hit the reset button (or power off/on) again.
  • Either the next time (or sometimes after repeating this once more), the metadata cache is reconstructed and the system boots fine, showing the SSD as a cache.


I believe this is an issue with the SSD itself, but how can I be sure since connecting it separately appeared to show no problems? I want to make sure it's not an issue with the motherboard, SATA ports, etc.
