Has anyone here been able to successfully remove the hard drive out of a Western Digital Passport? I have had one for quite some time and it has become unusable. I believe the hard drive has failed, but would like to salvage the case or at least the SATA to USB interface. If anyone has any tips or hints at how to remove the casing (I can only guess that the amount of flexibility by the blue circular LED indicator is some hint - but I am too scared to start taking a putty knife to it) I would greatly appreciate it. THanks.
