My External hard drive wont open when I click on it, It ask me to format it, so I did. But after i click on format nothing happen and it say "can't be format". How can i fix it by open it (keep my file) or format.
External hard drives have proved to be less reliable than internal ones owing mainly to the fact that they have a adapter-board attached to them (SATA-to-USB) and it's often this which fails, not the drive itself.
When that happens, the only fix is to extract the drive from it's enclosure (not an easy job), remove the adapter-board, then put the drive into a third-party enclosure.
However, that's sometimes not possible because the manufacturer of the drive may have given it a non-standard, custom interface which is neither IDE nor SATA.
To keep your files on this drive, you can try a free hard drive recovery tool that specifically offers a “Format Recovery” option for the user to process the format or unformat recovery problem. I have ever tried it on my Buffalo hard drive. It finally recovered 90% of my data from this mistakenly formatted drive. That is really efficient.
