I have a Vostro 400 running Windows XP.  I recently purchased a WD 250GB external HDD so that i could transfer my Outlook email file to the HDD.  Every time i tried to transfer the file I receive the error message "Not enough space on disk"  (The HDD was empty)

My Outlook email file is 7GB in size.  My thought was that a USB connection was not fast enough to transfer that large of a file.  So I returned the 250GB HDD and purchased an Acomdata 500GB external HDD with an eSATA connection.  I connected the new 500GB HDD to my motherboard directly using an eSATA to SATA cable.

As you can image I am still receiving the same error message "Not enough spacke on disk".  I checked on Acomdata's website for drivers and i also checked on Dell's website and found nothing so far.  The 500GB HDD works fine with my Toshiba laptop.

I'm not sure if it is relevant but i have two internal HDD and i can easily transfer the 7GB email file between the two internal HDDs.

Has anyone seen this problem?  And does anyone know how to fix it?
