A friend of mine dropped off a WD Portable 2TB with me that has failed, it shows in Windows as unallocated and can be seen by the 5 restore tools I’ve tried, in every case it finds loads of photos but they are all corrupted and won’t open, am I missing a trick here or is the disk finished with?
Try mounting the drive in a Live Linux distro. Otherwise it’s time for professional recovery.
Unlike Seagate portables, which are regular SATA drives with a detachable USB interface, WD and Toshiba portables have the USB jack and interface integrated into the mainboard, requiring expensive, $$$ modding for data receovery.
