I have a 2TB Western Digital external hard drive I got back in 2011, the mini-USB connector broke back in December, so I took it out of its shell and plugged it in via SATA II on my computer.. It showed up in Windows as Unallocated... ..After several hours of trying to recover and digging I eventually found out that Western Digital has "Hardware Encryption" on their external drives, what that means is, if the circuit board or connector breaks, you lose access to the data with no way to recover it unless you buy the exact same drive and salvage it. I called Western Digital and they wanted $800 to ATTEMPT to recover the data, heck no. I searched and found the PCB on eBay from a guy in China for around $23, after nearly a month and a half it finally arrived, I hooked it up to my drive and it works! This is also a reminder to make a backup of your data! I am doing so now. I would also NOT recommend Western Digital drives, they basically hold your data captive and you must pay extremely high amounts of money to recover it. At least the external ones.
