How do I read from a bad drive?
I have a drive from a PC that won't boot up because of a bad sector. I have connected this drive as an external drive to another operating PC. The aim is recognized as "Microsoft Office click-to-run 2010 (protected) 2010" but when I click on it, the PC says "access denied". I want to be able to read the data off of this corrupted disc. Is this possible?

Though other storage devices like USB flash drives, CD/DVD, etc., can't be used to keep the operating system for one or other reasons.

The bad sectors' data may be lost temporarily and permanently depending on the cause, i.e., hardware or software. Hardware errors are impossible to fix, and it would be best to back up the hard drive and replace it. Software errors can be corrected with a software application designed for a specific task.
