Hi, I am having a problem with my external hard drive not working. My laptop cannot read the drive, it does not display properly in my computer and when I try to click on it it freezes and the message appears "Drive is not accessible, parameters are incorrect". I used it about three weeks ago and it was fine so I don't know what happened. I always make sure to safely remove it and am careful not to damage it. The light still still turns on when plugged in and I can hear it trying to work. I really want to keep the files as they are from my previous laptop which died and do not have them stored anywhere else. My fault I know, but I had thought external hard drives were more reliable and I do not like the idea of cloud storage. Because of this I am hesitant to try CHKDSK. Is there anything else I can do to recover the files or fix the drive? If I take it to a computer technician would they be able to do it?
