I have a 2TB WD drive. I cannot access only one folder on this drive even though directory listing shows the folder name. When click it through My Computer, I get a message that I need to Format this disk. I have more than 20 folders and can access all others. I can change the properties of the files etc. but cannot open this folder. Has anybody else faced this problem and have a likely solution. I have already tried CHKDSK with repair.
