My WD Passport removable external hard drive of 1TB failed to initialize when I plug in its cable. This drive contains all my disc images. About 275 GB free of the total capacity. The drive appears in device manager as well as Computer Management in Disk Management. It is indicated as Disk 1 Unknown, Not Initialized. When I right click to initialize it and click the OK button, it reported a red X circular icon with the following text message "The request could not be performed because of an I/O device error". I have an idea of the genesis of the problem because the disk fell when I was trying to eject it from the system this evening 22nd of June 2016 in my office, although the fall is not that high of a distance. Please how and what can I do to get the drive Initialized. I need urgent help to solve the problem please. Thank you all. This is my first post since I signed up with this site or forum. Please pardon me for any inadequacies if there is any.

I believe the hard drive has failed. Passports, if the portable, do not need much of a drop to break, especially if the drive was spinning during the drop. 


Another issue with the passports is the USB bridge card is integrated into the drive's PCB which prevents the removal of the drive and placing it into an enclosure or using a USB adapter.


Have you tried another USB cable? If a different cable does not work I am afraid you are looking at using a professional data recovery service which is not cheap. It depends on how important this data is but the cost can be $800 and up.


Your location is Nigeria but DriveSavers is one of the better recovery services.

"...Not Initialized. When I right click to initialize it..."  -- Radvec

In a strange way, that process might come in handy later;  here's a snippit quote:  "...initialization...[is a]...high level format basically clears the drive by zeroing the data that keeps track of where all the data is on the drive. The data is still there (until you write over it), but since the drive's table of contents shows nothing in there it behaves like a blank drive..."


Follow JohnC's lead, he won't steer you wrong!
