2015年9月22日 · Select Split virtual disk into multiple files if the virtual disk is stored on a file system that has a file size limitation. Another reference has this to say: Choosing to split VMDK into 2GB files has quite no impact on performance. Anyway, the largest disk image file I've currently got (on my NTFS-formatted portable USB hard drive) is ~150GB.

The advantage is that the virtual environment can be easily moved to different machines and still run. The performance will typically be slower than using a physical disk itself because of the overhead involved, and the disk may also have to take care of operations on the host OS as well (depending on your setup).

2014年7月17日 · VHD is a HDD image file format, virtual disk is a device. There are many formats for virtual HDD images and VHD is just one of them (VirtualBox uses VDI, VMware has VMDK etc.). These are images, not devices. Virtual disk is a device that doesn't exist physically, so an emulated (or virtualised) HDD, CD-ROM or something like that.

2011年11月23日 · Disk image files reside on the host system and are seen by the guest systems as hard disks of a certain geometry. When a guest operating system reads from or writes to a hard disk, VirtualBox redirects the request to the image file. Like a physical disk, a virtual disk has a size (capacity), which must be specified when the image file is created.

Size is number of bytes ... -m Specifies a drive letter or mount point for the new virtual disk ... -o rem Specifies that the device should be created with removable media characteristics.

2020年11月30日 · In September, 2023, a pre-release of WSL (2.0.0) enabled a new "sparse" mode for disk images which is intended to automatically shrink the image when files are removed. (Especially given the warning above) Always maintain good backups, especially when using newer features that affect the entire virtual drive. I have not tested this personally yet.

2012年11月24日 · I clued in that it had something to do with the partition table, since windows disk manager showed the old partition layout after attempting to create a volume+format, despite the fact that I'd picked a different volume and file system size (i.e. attempting to create a 4G volume and filesystem restored the previous 2G partition in the disk ...
