After trying to install a program on my pc from an install file on my hard drive, It seems to have corrupted my entire hard drive. Now, whenever I plug the hard drive into my computer (or any computer, I've tried about 3) windows tells me I need to format the drive, which I do not want to do as I would lose all my work! Please help.
My portable hard drive has become unreadable by windows. I'm getting the error
"H:\ is not accessable , The file or directory is corrupted and unreadable"
In Windows disk management the drive is showing up as RAW file format

I then hit P to list files and the message displays "Can't open filesystem. Filesystem seems damaged"
After reading some other posts on this forum, I have entered the "advanced" menu (filesystm utils) and selected the boot option. The following information then displays

If the boot sectors are listed as ok, do I still need to Rebuild BS? Please help, I have a lot of files on my hard drive which I cannot afford to lose. Any advice would be appreciated
