Unable to compress the drive.

    Unable to use the hard disk compressing the drive. When using DriveSpace or Compression Agent, the following error appears: a. "Drive C cannot be compressed because it is a FAT 32 drive. ID Number: DRIVESPACE738" or b. "This program has performed an illegal operation and will be shut down. If the problem persists, contact the program vendor." In these cases, when you click [Detail], the error "DRVSPACE caused a general protection fault in module DRVSPACE.EXE" appears.

    If you create partitions of the hard disk drive by FAT32, you cannot compress the drive by using a Windows standard tool because this is one of the specifications of Windows. On VAIO, the hard disk partition is FAT32.
