[NAME]  The 32-GB mSATA is used as a cache for the HDD, so you can't simply swap in a new mSATA card. If you do that, Windows won't boot because it won't be able to find the cache that was stored on the old mSATA SSD. You have to disable acceleration first. Then you can replace the mSATA SSD and re-enable acceleration. Read this thread.  mSATA is old tech so you don't want to spend a lot to replace/upgrade the 32-GB SSD because it won't be usable in any future PC.
Hello, The utility CrystalDiskInfo tells me that my "SAMSUNG SSD CM851 mSATA 32GB 32.0 GB" needs replacing. Is this a simple case of removing the old one and adding a replacement with the same specs, or are there other things that I need to do in the BIOS also? Thanks in advance!
