If you want to recover your data before repairing any bad sectors then I suggest you use a program that can read a bad sector more than once to increase your chance of being able to get a good read on a bad sector. This would give you a good chance at recovering your data from the bad sector. You might not always be able to recover all the data from the bad sector so I suggest that when your data is recovered that you check and make sure all of it is there.

One such program that can read a sector more than once is.

1. Media Tools Professional

When you need to recover data from bad sectors then the program below is one of the better programs to use on a hard drive with bad sectors. If the bad sector cannot be repaired then data is moved from the bad sector to a good sector.

1.SpinRite

Also if you want to try and repair the drive with bad sectors without erasing all the data on the hard drive then spinrite is one such program that can do this.

PC-Check is a good computer hardware diagnostic program that can help you repair bad sectors on your hard drive.

PC-Check does not have a bad sector repair option in it’s menus but the way to repair bad sectors with PC-Check is to use the option that erases all the data on the hard drive you want to remove the bad sectors from.

This option is usually the Low Level Format, Destructive Write Test or Low Level Initialise Drive option. The option you choose in PC-Check will be the option to erase all data on the hard drive with bad sectors. This option may be called something different in each version of PC-Check.

Make sure to use a data recovery program first to recover any data you want off of the drive before using PC-Check to erase it.

PC-Check may not always be able to remove the bad sectors from the hard drive so this may not always work.

One reason that PC-Check may not be able to remove bad sectors from a hard drive by erasing it is because over time the magnetic media on the hard drive can become weaker. A hard drive comes with spare sectors that are used in place of the bad sectors when needed. When there are no spare sectors left on the hard drive then any other bad sectors that the hard drive gets cannot be repaired.

Also if you are interested in a good hardware diagnostic program to check all the hardware in your computer for problems then PC-Check in my opinion is the best program to use for doing this.

We have read that using the following program below may be able to help repair bad sectors that a Low Level Format may not be able to repair.

1. HDD Regenerator

Also if you want to try and repair the drive with bad sectors without erasing all the data on the hard drive then HDD Regenerator is another program that can do this.
