Hi, Am having a 1 tb external wd hdd 2010. There was no issues till last month. But now it is not mounting. It is showing that one bad sector is found… What to do please help me throughout this situation…
When a good hard disk comes up with one or more bad sectors, the disk goes bad; and, when such a situation occurs, the data stored in the bad sectors may get lost. There are scenarios when the cause of bad sectors could be a faulty drive head. In such cases, there is a likelihood of spreading the issue to several other sectors of the disk. Hence, in situations where the hard drive experiences one or more bad sectors, it is highly advisable to back up the disk data or fix the bad sectors instantly.
Below are the common signs and symptoms that indicate bad sectors in a Hard Drive:
• Strange noises on booting, especially at the time of read/write and hard disk drive opening.
• Error Messages like “Files become corrupt while running a program or reading a file”.
• System is consuming a long time to run a program or read a file.
• System showing a Blue Screen.
• When your system shows warning message such as a “General error in reading drive C” or “Sector not found”, even though it is not attacked by a virus.
• When Windows fail to complete the hard disk drive format - Quick as well as full.
