I have an old external 750GB Western Digital hard drive which has quite a bit of important data on it. when I connect it to my computer, I am able to see the device recognized but once when I click on it, I am not able to access any of the files inside. Problems starting creeping up some time back and as I result I was able to sporadically get access to the files but now I am not able to access the files at all.
I am not sure what is causing the problem and was wondering if you could help me diagnose and fix the problem.
I have tried using the dd command in my ubuntu distro to create a backup.img but is taking too much space. Is there an easier way to restore the hard drive to working condition or at least get the data off the hard drive? Any comments on the start of the hard drive?
