PowerISO shows "Open USB drive / hard drive" dialog. If you are using Windows Vista or above operating systems, you need confirm UAC dialog box to continue.

Select the correct drive from the drive list. The detailed information of the drive shows in the dialog, such as capacity, sector size, total sectors, and etc..

Click "OK" button in the dialog.
