HDD problem~! Memory DROP!!!!

[fishballfung]

My HDD was divided into 3 partition, which are 15GB, 35GB and 25GB.
and the 15GB drivegot some problem this few days, the remaining memory dropped every time when I switch on the PC, the memory was remain 50Mb only, but I'm sure I only used 3GB of the drive.

Whats Happen? Would it be some problem about Bugs or virus??

Really need help. thanks a lot

I assume you are using Windows..

Empty your Recycle Bin?

Run chkdsk on the partition to fix any filesystem errors.
Download Sequoia View and run that to see where your disk space has gone.

Memory drop??? do you really mean the reported size of the HD is smaller from 15G to 50Mb??
open IE. (assuming your using windows.) run the mouse over the HD in question. right click --> properties..--> under general tab it will give you FREE space, Used Space and Total size... under Tools --> error checking click scan now...to repair --> carefully write down any thing it says..
PS: yes, it can be a Viris or trojan

it can also be a very large file that was "deleted" but the space has not been used by windows yet.
