Could anyone give me some advice on repairing or recovering data from a HDD external hard drive. I pulled out the USB while transferring some files into it and now when i plug the usb of the external hard drive into the computer it says its corrupted or unreadable, and i get an option to format it, but i dont wanna lose the data in the hard drive. Also, i cant seem to safely remove the hard drive, it says the drive is in use. what should I do? is there any data recovery or repair program i can get?
