The hard drive is going to fail in the near future. I recommend you back up your data before the hard drive fails completely.
When the hard drive fails, replace the hard drive, and use your Compaq recovery disk to install Windows and the device drivers plus your programs to get the laptop working again.

When a hard disk has bad sectors, these sectors can be fixed by running check disk. This is a temporary fix as the hard disk is nearly worn out and it will get more bad sectors and evenually the hard disk will fail completely.
Bad sectors occur when the magnetic oxide on the disk platters is worn out and data cannot be written or read from these sectors.
To run check disk click Start - My Computer - right click on C Drive and click on Properties - click on Tools tab - then Check Now in Error Checking
I suggest once this has been done, you back up your data and purchase a new hard disk ready to install Windows etc. when the hard disk fails completely. You may want to install a new hard drive before the old hard drive fails completely.
