Yes, this is correct! My C Disk is a SSD NTFS.
It seems the problem is that OPEN can not manage Images bigger than 2GB TOTALLY, I mean VirtualSD1 + VirtualSD2.
In fact now it works with 1024 as VirtualSD1 and 100 as VirtualSD2. But if I try with 1.8Gb and 200Mb it hangs Up.

Can you try again with the latest development build? 179-gd1a2f40 and later should have the fix. But I didn't actually test it on Windows yet, so, please help me here.

Sure Manuel, i will try asap.
Meanwhile i tried to mount the .SD file in windows with no result as se know.
I tried Mfrsccsd and IDE to copy 700mb from virtualhd to virtualsd, but also with a turbor and the f9 throttle option i gave up after 2 hours.
I think that a tool like diskmanipulator is needed also to manager virtualsd, better if with a small GUI.
Please :-)

Try again but first set maximum frameskip to 100...

How much data is it anyway?

Done on My LapTop while travellig by High Speed Train from Turin to Rome
Maybe the first time OpenMSX works at 300km/h ??

Let's say IT WORKS !
I started from zero with the latest version you suggested and I could create a 4096MB virtualSD!

Then I tried with TurboR+IDE with

reverse stop
set maxframeskip 100

and the trhrottle option to speed up the copy from IDE to SD.

It takes only 7 min. for 700Mb.

Now It's the time of a virtulaSd manager as diskmanipulator is for virtualDisk :-)
If you permit I'll write down a vademecum about all my experience with OpenMSx and MFRSCC+SD.

Fantastic, thanks for reporting!

Yes, we/someone should teach diskmanipulator about different partition table formats some day.

Of course you're free to write anything you want about openMSX. I'll read it with great interest!
