FAILING HARD DISK:
There are many signs of impending failure before a hard disk finally crahes on you. Some of these signs may be:
Slow access times on the affected drive.
An increasing number of bad sectors when running scandisk and chkdsk.
Unexplained Blue Screens.
Intermittent boot failures.
Detecting a failing hard disk can be tricky because the early signs are subtle. Experienced computer professionals can often hear a change in the normal disk spin. After the disk deteriorates further, you’ll see the system crawl to a standstill. Write processes will take a long time as the system tries to find good blocks to write to. This performance slow will occur when using NTFS but FAT systems will likely bring you that lovely Blue Screen of Death.
When you notice the system slowdown, run scandisk or chkdsk, depending on your operating system. If you notice a bad sector where a good sector existed , that’s a clue that the disk is going bad. Back up the data on the disk and prepare for it to fail soon. Make sure you have a spare disk ready so you can replace it when it fails, or, even better, replace the disk as soon as you notice the early signs of failure.
Disk noise and scandisk/chkdsk are your best indicators for identifying a failing drive that’s leading to a system slowdown.
That may your problem. Try what it says and see if you notice a bad sector.
