Removing Zeroed Blocks
Use the vmkfstools command to convert any thin, zeroedthick, or eagerzeroedthick virtual disk to a thin disk with zeroed blocks removed.-K –punchzero
This option deallocates all zeroed out blocks and leaves only those blocks that were allocated previously and contain valid data. The resulting virtual disk is in thin format.

Gabrielle,
I did the sdelete -z and this cleared up the space on one of my drives. Which worked awesome for this particular issue I ended up just added a new drive to the system copied the 5 GB of data over changed the drive letter, rebooted and brought my application back online. Worked great. Thanks for the information.
