My computer could not boot because of faulty had drive. I installed a new hard drive but when I connect the old hard drive to recover my document the error message comes up the the disk is not accessible, error performing in page operation .
Occasionally a hard drive will fail and you will lose the data. There are stories about putting a failing hard drive in the freezer over night and then connecting it and trying to copy over the data before it warms up again, but I have never tried it. If you really must have the data from the drive, you will have to pay a premium price to have the platters extracted and the data copied.
