Hard Drive Failure Error at PC Startup
I'm using Windows XP. Today I had a problem with my computer. At the startup screen, an error message came saying, "Immediately back up your data and replace your hard disk drive, a failure may be imminent".
The performance of my computer is also very slow now & I'm having problem in using different applications.
I have saved all my important data on a portable hard disk.
Please tell me why this error occurred.
