Hi,
I am configuring a Linux under VirtualBox-5.0.0-rc3 and one of the partition
will be NTFS. The disk is raw disk, on host exposed as /dev/sdc, on guest
appears as /dev/sda.
It seems detection of virtual drive geometry fails or mkntfs is broken. Seems I
can provide mkntfs with cyl/head/sect counts but what is the cause?
It seems very dangerous to blindly set starting sector to zero and starting
zero-ing my drive.
I get same mkntfs results from the host Linux system running 3.10.78 kernel and
guest linux-4.0.4 (VirtualBox 5.0.0-rc3, 3TB RAW disk used). I don't think it
is an issue with VirtualBox but with mkntfs. Or, does this happen because I
created the NTFS partition entry under a "broken" virtualbox (and subsequent
attempts to run mkntfs will fail in the same way under both host and guest
operating systems)? I am not sure whether I created the partition table from
guest or from host, I was fiddling a lot with GPT and MBR tables and am just
not certain.
linux_host# gdisk /dev/sdc

linux_host# mkntfs -n /dev/sdc5
Running in READ-ONLY mode!
The partition start sector specified for /dev/sdc5 and the automatically
determined value is too large. It has been set to 0.
Cluster size has been automatically set to 4096 bytes.
To boot from a device, Windows needs the 'partition start sector', the 'sectors
per track' and the 'number of heads' to be set.
Windows will not be able to boot from this device.
Initializing device with zeroes: 100% - Done.
Creating NTFS volume structures.
mkntfs completed successfully. Have a nice day.

Above I show it with "-n" option but initally I ran the command without it. so,
maybe beginning of my /dev/sdc drive was deleted?
