Yes but that's for CD (just like I thought)
Try going to Device Manager:
Start-->Run-->devmgmt.msc
Click on the + sign to expand IDE ATA Controllers
Right click on your ATA Controllers and select uninstall (note: this does not hurt your data)
Restart
Allow Windows to find and install your ATA Controllers again (basically the HardDrive)
Open My Computer and confirm you see your HardDrive and partitions.
If that doesn't help, you may want to do a full updated Spyware scan, or Antivirus updated scan.
If that doesn't help, consider replacing the IDE cable
