I have 2 remarks:
-Maybe the point that you need some free space before the ntfs partition may be valid, I never succesdeeded getting the disk to recognise as a internal disk after i reformatted the NTFS part (it showed as usb)
-50Megabyte/sec is impossible over USB in my opinion .
I don't need the extra space, what is 7.84 MiB these days?, but i need an 4k aligned ntfs partitition
to achive the maximum possible transfer speed of my drive.
Because the mede8er is not creating the aligned ntfs partition automatically i had to create it myself
and by doing so i accedently destroyed the gap in front of it.
Now as a workaround i have created the aligned partition a little smaller and with 10 mb unallocated space
in front to save the old gap and this does the trick.
But the dangerous part is that the mede8er firmware is using a part of the disc that is destinated
as "unpartitioned" as its private storage area and if this space is covered by the ntfs partition strange
things can and will happen, like corruption of the ntfs file system for example.
And that is why everything started in the first place i think, the developers have build in the final V4 firmware
an extra check to see if the data in the unpartitioned part of the disc is still inplace and to only accept a harddrive with this
special "signature" as an internal disc.
And otherwise mount it as an external "foreign" disc to protect the system against destroying the data that lies in the gap.
Older versions (pre v4final) don't have that check so everything seems oke on those systems
but if you then create your own ntfs partition it is bound to get slowly destroyed!
The bottomline is: You have to keep a reserved space at he start of the disc to keep it healty and ok.
And for the transfer speeds: the disc was connected via sata to my windows xp system,
and even so the copying took several hours at 50 MB/s average.
Via Usb the speed is much lower, more in the 20 MB/s if i remember it correctly.
