Solved Drive Recognized..Will not perform Chkdsk Tags: Hard Drives Chkdsk Western Digital Storage Last response: August 25, 2009 7:45 PM in Storage Share chriscotty August 14, 2009 4:00:54 AM So I have a 500gb External Western Digital drive that all of a sudden stopped being recognized.It had (hopefully still has 150 gb of data on it). I went through several steps and now device manager in XP recognizes it as a healthy 465 gb unformatted drive. So I go to DOS and enter E: so I can go and run chkdsk /r and then it hangs forever and finally and I finally get a cyclic redundancy error. I have connected it to two computers and the same error occurs. Any other diagnostic tools or other suggestions ?
