I have a p4 3.2Ghz on a 915gav mobo with 1gb ram. I am using win XP SP2. I have 2 120Gb hard disks partitioned into 7 partitions. I want to format on of the partitions but everytime I try to do it I get a message saying the drive is locked by some windows utilities and needs to be dismounted before trying to format. tried to format in command prompt and tried to dismount the drive but it says unable to dismount. I want to format the drive becoz even though the drive is empty the drive is showing around 2.5 gb data, which seems to be in every partition, i.e. in every partition the data quantity in the drive exceeds the actual data by around 2-2.5gb. Can anybody help me in formatting the drive and how to get full storage in a partition without having any hidden data.
