Hey. I've bough new WD Passport 500 Gb for backup purpose. And i've backed up all office/personal data on drive and deleted some old data from orignal source as well. Now today i thought of upgrading the drive firmware. And it upgraded successfully, but it drive stopped appearing in control panel, Disk management and device manager. This is so embarassing for me, as i bought this drive for backup and the whole backup is unaccessable. Can any one please help me out in this as WD team are stupid a$$es and cant do anything except replacing the drive For all WD Useres. please don't upgrade the firmware or drive software. But any one got any solutions how to downgrade the firmware or possible way to access the data?
