I need some help troubleshooting a hard drive problem in my Windows 7 computer.
While using Lightroom, my computer crashed. Upon rebooting I relaunched Lightroom, but it could not load the catalog, claiming it was corrupt. Lightroom offered to repair the catalog, so I let it try, but it failed. I then switched to a backup catalog and Lightroom was able to load it, but could not locate the photos.
I exited Lightroom and in Windows Explorer inspected the hard drive (Drive D) containing the photos. Drive D is an internal 1GB drive that has been in the computer since I built it in 2012; it has not exhibited any problems at all prior to today. I can see all of the directories on Drive D and can drill down through the subdirectories in each parent directory until I get to the bottom subdirectory. At that point the system hangs and then displays the message: “The request could not be performed because of an I/O device error”.
I tried to run checkdisk on Drive D (right clicked and then selected “Tools”), but checkdisk will not run (and doesn’t give an error message).
All of the other drives on the system (including another internal drive, Drive F) seem to be working fine. Moreover, checkdisk runs successfully on Drive F, with no reported problems.
At this point I assumed that Drive D or the files on it were irrevocably damaged. But here’s the part I don’t understand: when I boot the computer in safe mode, I can access Drive D and its files without any problem!
So my question is: should I just go ahead and replace Drive D (seems like the simplest approach) or are there some additional troubleshooting steps I should run first?
