<drive_letter> is the drive letter to change the storage parameters for; <max_size> is the maximum size with a suffix that designates which units you're using (typically MB or GB). If you typed Note: When you change the size of a shadow volume, it's truncated so that the oldest entries in the volume are deleted first. Also, if you leave off the /maxsize switch, this allows the shadow volume to grow without limits. However, the /maxsize setting can never be less than 300MB for any volume.
