My Lacie external HDD just failed on me, and although the drive is covered under warranty (I just have to pay return shipping) they told me that data recovery will cost $13xx.00+. 1. Does data recovery usually cost that much? They told me I need to use a certified class 1 clean room data recovery center. 2. Is there any way to make sure the contents on the HDD are not recoverable once I send it back to Lacie. I have very sensitive information on there, and although they said they magnetize it to render the data unrecoverable, I'd like to try to do something similar on my own before it leaves my possession. Currently the drive cannot be read by my laptop (making a hard clicking noise with whine). I was told the HDD is dead by the technician.
