Can't access my 1TB Buffalo external HD Tags: Hard Drives Buffalo HD Storage Last response: January 31, 2013 1:27 AM in Storage Share rufo January 30, 2013 2:26:10 PM Hello all, I have issue on my ITB buffalo ext HD, i can see the blue light on the HD when connected to my laptop, but i can't access it since i the HD can't be seen in the "My computer" list of drive. Trying to access in disk management but also error found after initializing the disk "the request could not be performed due to I/O device error". I check the disk capacity it appears 2Tb instead of 1Tb br, rufo More about : access 1tb buffalo external | E-mail me updates | Report abuse Reply to rufo Register or log in to remove alvine January 30, 2013 2:34:12 PM is the external hd making any clicking noises? | Report abuse Reply to alvine fzabkar January 31, 2013 1:27:41 AM If the capacity is being reported as 2TiB (not 2TB), then this is symptomatic of an internal problem with the HDD, possibly a damaged firmware module.
