I Have had this external drive for 5 years and i'm starting to wonder if it's going bad i ran test on it by using Acronis and sea gate software and it shows the results that it's 100% healthy but every time i plug it into the computer it say's right off the bat a partition needs formatting and if i choose format it says it can't find it i hear that most hard drives have a hidden partition on them anyway that contains drivers for the hard drive but even so it shouldn't be asking me each time i plug it up to the usb on the desktop to format it then when i attempt it it says partition can't be formatted could you please or anybody give me some input on this please thank you!?
