Remember that crappy WD Passport 160GB that dropped about a foot and died on me completely?
Well, you will be glad to know that the data within the drive has been almost completely recovered. 120GB of it, by a company I dealt with in the States: First Advantage Data Recovery to the tune of US$1,400!
They’ve just sent me the directory listing and said that they will send me the data on an external drive today. Yippee!
The test results for your failed hard drive are in and have shown that the Head Rack Assembly is the failure mechanism. The Head Rack Assembly (HRA) is the latticework that supports the read/write heads; there is one head per surface. Attached to the back end of the assembly is a voice coil positioned between two ferrite magnets. Energizing the voice coil will drive the read/write heads to the location on the media for reading or writing.
When this device fails, the drive will typically make a clicking sound. The only choice here is to replace and realign the failed HRA with one that matches it from a â€œdonorâ€ drive. This transplant procedure is performed in a clean room environment by highly skilled engineers. This procedure does not fix your drive for you to reuse but instead enables us the chance to acquire the raw data (sectors) from the drive. If we have a good sector dump from the drive and the file system is not affected, then we will be able to see the folder and file structure that you were used to seeing and recover your data. What is described here is the primary cause of failure, other issues may exist.
Needless to say, the second drive that went belly up on me, the MacBook’s internal drive is on the way to them as I write this.
