Unable to create folder

Data and/or file structures on the drive may be corrupt. Run the check disk program or other disk validation and repair utility on the drive. To do this:

1. Open Explorer or My Computer (Press Windows+E).
2. In the right pane, right-click on the drive you want to validate and select Properties.
3. Select the Tools tab.
4. Under Error-checking, click on "Check Now".
   
   
   
5. In the next dialog, make sure the option "Automatically fix file system errors" is checked. If you want a more complete validation and repair check the option "Scan for and attempt recovery of bad sectors" (although this takes considerably longer to complete).
   
   
   
6. Click on Start.

Several software products that offer an extensive range of disk diagnostics includes Fix-It Utilities Professional and SystemSuite Professional. Other diagnostic products include Eurosoft's PC Check and Iolo's System Mechanic.

If you remove a storage device while in use, this error can occur. For example, removing a USB storage stick or a SATA drive while it is being written to can bring up this error. With luck, rebooting should clear the problem, although the storage device may be corrupt. It's wise to run the Check disk program on the drive before trusting the data. To do this:

1. Open Explorer or My Computer (Press Windows+E).
2. In the right pane, right-click on the drive you want to validate and select Properties.
3. Select the Tools tab.
4. Under Error-checking, click on "Check Now".
5. In the next dialog, make sure the option "Automatically fix file system errors" is checked. If you want a more complete validation and repair check the option "Scan for and attempt recovery of bad sectors" (although this takes considerably longer to complete).
6. Click on Start.
