Because of the interest expressed in the chat, I thought that this article on data recovery secrets would be a good read.
Kroll Ontrack, purveyors of data recovery, give a glimmer of hope to those with wrecked RAIDs in Tom's Hardware Guide's 7-page explanation detailing their step-by-step process, including preventative measures, proper handling tips, different types and levels of damage, and an overview of various Ontrack recovery methods.They stress the obvious solution to make a habit of defragging and backing up your data, however if it weren't for the irresponsible / lazy demographic, Ontrack would be counting their food stamps. They also encourage potential data-loss victims to stay calm, as freak-out sessions oftentimes yield impulsive and regretful decisions for data that might be recoverable. "In 2005, Kroll Ontrack processed 50,000 recovery cases. Ontrack was able to complete 40% of incoming orders successfully right away. The remaining 60% had to be taken to the clean room, where 75% of data recoveries were successful." The stats sound promising if you're in need of a serious data resurrection, and as long as you're willing to cough up a good chunk of your savings.
