I had a problem with an external 297 gb hard drive. Windows 7 corrected the file system errors. however, I am concerned that the drive may have disk errors. I have repeatedly started the program to scan for bad sectors, but it runs very slowly after the first few files and never seems to finish. 1. Is this normal? How long should it take? 2. I would like to be able to track the process with task manager. How does this process appear in task manager?

1. Not only the size plays the role but the type of interface. IDE is the slowest, SATA is faster,... The interface between external disk case and computer plays the role too (USB 2, USB 3, eSATA, IEEE 1394A vs B,...) 2. If there is any serious problem with your HDD, then the time may be infinite. 3. Use tools that HDD vendors provides for their disks. 4. What is normal or abnormal is not easy to say. 5. Task manager is not suitable tool for tracking testing. Without knowing more details it is practically impossible to do any statement. Regards Milos
