Question: I transferred all data from my laptop hard drive D to an external hard drive, but I was unable to open the external hard drive when I connected it to the company’s computer. Windows said an error message "You need to format disk in drive F before you can use it". I can’t understand why it said such a message since I was still able to open the external hard drive on my laptop last night. Then I connected the external drive to my laptop just now when I came back home, but I also get another message "Disk in drive G is not formatted do you want to format itnow?" I don’t want to format the drive because I don’t want to lose all data inside it. But I get another message when I refused to format the drive "G: is not accessible." Please help me out and recover the external hard drive.
