I would not take it personal then.
I thought of putting my notes in here for other who fancy experimenting.
My place is not particularly clean and I even saw dust on the platters. I spinned the drive while open to gently blow away the dust before sealing it back.
I have to say that we have assumed the lost of the data and that I would not have tried should the data been very important.
Information from client
Computer is unable to see the external Hard Drive.
Client informs that the HDD had fallen from a heigh of about a metre. Wooden floor.
HDD was working fine before that.
Client cannot remember if HDD was plugged or unplugged at the time of falling (that would have determined if HDD was on or off)
When connecting the HDD to the computer, the computer fails to identify external Hardware.
Mini USB connector does not seem damage as power light is on.
By the sound, HDD does not seem to be spinning. There is no clicking noise, but 5 long beeps.
The following website helps identifying the problem:
Western Digital WD Data Recovery - Datacent
Problem Spindle seizure. Arm is stocked and cannot read the data.
HDD needs to be open in a 100% clean environment, client is not prepare to pay any money to data recovery companies, client instructs that I can disposed of HDD as I pleased.
I Proceed to open the HDD and force the arm into its position.
When I sealed the HDD the data was back.
I managed to recover 377GB out of 460GB
Most files were over 600 MB.
HDD is still working fine, but seems to take a long time to open up files, it is probably beginning to fail.
The files that I have not been able to copy do open fine. So I am trying a program to recover the remaining corrupted data.
Thanks for your help
