Hello. Maybe somebody encounters with the same problem
I have OS FreeBSD on VirtualBox which consist 6 disks (if exactly 6 images files of hard disk) merged in zfs pool. Host OS is Windows 7. I need to connect physical hard disk (volume 3Tb with GPT, FS-NTFS) to VirtualBox that copy data with zfs pool to physical hard disk and later will open them in my host OS the Windows 7.
I`ve connected hard disk in this way created link to physical hard disks (VboxManage.exe internalcommands createrawvmdk -filename g\Images\wdnas.vmdk -rawdisk \\.\PhysicalDrive5) and connected to VirtualBox.
My disk has appeared in FreeBSD but I can`t mount it in system. FreeBSD write "Invalid argument". I recreate a partition with help "gpart", after that FreeBSD has mounted partition and I can copy data on my physical hard disks.
But when I have tried unmount my hard disk VirtualBox give me message error "The I/O cache encountered an error while updating data in medium ahci-0-6 (rc=VERR_ACCESS_DENIED). Make sure there is enough free space on the disk and that the disk is working properly. An operation can be resumed afterward." I tried to check item "Use host I/O cache" but it didn`t help.
When I`ve seen windows disk manager to my hard disk didn`t have the partition and look like unallocated space.
Help me please, I don`t know how i can to handle with this problem.
Thankful in advance for the help
