I partitioned my 320GB SATA drive to 80GB for Windows O/S during the install procedure- now my drive is only listed at 80GB. How do I assign a drive letter and/or format the balance of the drive?
Start > Control Panel > Administrative Tools > Computer Management
Select "Disk Management" under the "Storage" root. Here it will show the unpartitioned space remaining on your HDD. Right-Click gives you the option to partition and format.
