I am using a Mediasonic K32-SU3
Mediasonic mentioned they are using VIA VL700 chipset (source: http://forum.mediaso....php?f=13&t=174 ), now that guy who was asking that question is using a slightly different model than me, his model has some aluminum in the case, but as far as I can tell they are very very similar models internally (i think only the external of the model is different, not 100% sure) so I wouldnt be surprised if we were using the same chipset, but I also see references to jmicron when discussing firmware or drivers or stuff like that
And yes, I remember a few times that the second I manually started crystaldiskinfo, there was a sudden dismount. although it was not every time, only 2 times I started crystaldiskinfo out of maybe 100 did that ever happen, but I remember it happening., The thing is this is a very hard to reproduce problem, as sometimes it works fine, sometimes it doesnt, with EITHER program
