It's standard advice to always have a good backup of all critical files.. If you've got a 400 GB drive full of important files, you should have a second 400 GB drive to use as a backup. (Of course it's also possible to make another reliable method of making copies of the files such as DVDs, etc.).. Do you have such a backup?
If no such backup exists, then you'll need to stop performing any work on the removable HD and decide how important the files are.. For marginally important files, there are free recovery software options or if the data is extremely important, try a professional.
Hope this helps.
I have a 400 gigabyte Western Digital portable hard drive where I keep all my private files. I have about 2 years of files on there which I simply cannot afford to lose.
I noticed lately it began working funny, like accessing a photo folder would take a bit longer than usual.
So I decided to get all my files off and format it. I got about 30gb in (with some files impossible to get like on a scratched disk) and then midway it crashed.
Now I can't access it without the message popping up telling me to format it, even tho an hour ago it was working normally.
Anything I can do?
