Fixing the 2.72 8M Issues

Hello there,
One year ago I returned my quad (wich was already 8M version) because of a failure on one channel.
Looking at the work done about the 8M version, I ordered another one and had another try.
Sys 1.62, Fw 2.72, APP v112 stock.
I installed the forked 8M Gabonator version from roberttidey on slot1, Wilddcat3.3 for 8M devices in slot 2, and quadpawn in slot 4.
They work, and I managed to save valid bmp/wav with gabonator. I c’ant before, so I was enthousiast.
But, after having played with gabonator calibration, Quad calibration etc, Im sorry to say I finally got the famous Assertion Failed while restarting gabonator (and lost calibration like before) : code 460 shortly and 464 source/core/settings/cpp before starting the app.
And I don’t remember how to recover from this (reinstalling Gabonator App ?)
So what do you think about that ? I’m not sure if this is an app saving conflict, or only gabonator not perfectly patched, but the 8M problem while saving seems always here.
I didn’t try to write something with Wildcat app for now.

Is there someone today who has at least one application working perfecly on 8M devices ?

Edit : I have just repaired the FAT with chsdsk /f
I did a few tests with gabonator. This is not a side effect from others slots and apps.
I succed to record several files without problems while restarting : Calib data, settings, bitmaps, wav, csv… but after a moment, they appear not readable, and finally the app corrupt the entire FAT. It is not constant, but sooner or later this happens.
I think that the corruption of CALIB.DAT is fatal.

About wildcat33 : All seems right, CFG (prepared per the manual), bmp… so perhaps the only way to go for stablity ?
Pawn is ok too.

Thanks for your comments
