This is the most common answer I find over in the business enterprise side of the market is:
"Never run CHKDSK on a Solid State drive. The partitioning and MTF are not the same as a standard magnetic drive."
I have never run chkdsk on my ssd's. chkdsk was designed for hard disk drives not ssd's.
Over here on the gamer and enthusist side of the market it gets kind of crazy. Visit enough forums and you will see all sorts of answers and opinions. It is not unusual to see posters go off on a tangent.
foscooter - chkdsk will run without causing any damage but it won't accomplish much of anything.
