I had trouble coming up with a subject line for this post, but I wanted to make sure I got it blogged because I know a lot of people that have been running into the same problem.  The cause of the problem has nothing to do with VPC, but I wanted to put it in the subject line so searches would find it; this problem typically surfaces when coping VPC images because of their size. 

Problem:  When attempting to transfer VPC images onto my Western Digital external hard drive and I was consistently getting an error saying that the "Disk drive is probrably full".  I had a series of .rar files that I was extracting directly onto the external drive. 

Cause:  If you get an error like this, check the file format of the external drive and see if it is FAT32 format.  Many external drives come pre-formatted as FAT32 to support Windows and MAC and FAT32 will only allow you to copy files that are approzimately 4 gigs or less. 

Resolution:  To resolve this, simply use the CONVERT command in the windows shell to convert your external drive to NFTS and you should be good to go.  Simply launch a command shell (run as administrator in Vista) and type convert [drive_letter]: /fs:ntfs.

Hope this helps.  This has been catching quite a number of people.
