WD 1TB External Harddrive showing as 2TB Tags: Hard Drives Western Digital External Hard Drive Storage Last response: August 26, 2011 11:33 AM in Storage Share SriSri August 15, 2011 9:27:51 AM Hi All, I have a strange problem with my WD 2.5' 1TB external hard drive. I am not able to access any content from it. It is showing 2TB as its capacity in all the partition tools but not allowing me to create partition with an I/O error. Everytime I connect the hard drive, the device is getting recognized and showing in the the Device Manager under 'Disk Drives'. But it is not showing in the disk manager. Is there any way to resize the disk capacity back to 1TB and get it into working condition. Regards Sri More about : 1tb external harddrive showing 2tb dark_lord69 August 15, 2011 2:49:12 PM Did you happen to add it to a disk array like "just a bunch of disks"? This would make it seem larger than it really is by combining more than 1 drive. Otherwise I would call the manufacturer cause it sounds faulty to me. m 0 l fzabkar a c 315 G Storage August 16, 2011 1:49:25 PM Your drive is dead. :-( Try one of the following diagnostics: HD Sentinel (DOS / Windows / Linux): http://www.hdsentinel.com/ HDDScan for Windows: http://hddscan.com/ How does Microsoft's UVCView utility see the external drive? http://www.users.on.net/~fzabkar/USB_IDs/UVCView.x86.ex... m 0 l Can't find your answer ?
