Does not show up in Disk Management top portion to adjust drive letter (only at the bottom where it says disk is unknown and if I right click it tells me to initialize disk). Only shows up in Device Manager simply as the letters "WD". It passed a quick test with WD Data Lifeguard Diagnositics but failed an extended test stating "test found bad sectors that may be repairable". Another note the blue light on the device is on and working. How would I proceed? I tried use recovery programs like Recuva but since device is not recognized on my computer the programs dont find the drive.
