Who Killed My Hard Drive?

Crashed hard drives can cost a company thousands of dollars in repairs, lost productivity, and lost revenue, according to a recent study by the University of Pepperdine. The study looked at the most frequent causes of drive error and the extent to which a "fatal" error could harm a computer. Hard drive failure was the factor behind 38 percent of data loss incidents--second only to physical theft--and in about 30 percent of these cases, data was lost as a result of drive problems that corrupted the disk and made it unintelligible. Attacks by hackers and human error accounted for about 13 percent and 12 percent of data loss cases, respectively. When the IT cost of a failed drive--approximately $1,150--is coupled with the cost of lost productivity--around $1,750--the total cost of each failed drive comes to roughly $2,900, according to the study. If faced with a failed drive, a company should leave recovery to a professional, since around 15 percent of all non-recoverable data loss incidents in the study were caused by improper recovery attempts. "Non-professional tools and system software often fix errors by overwriting the file system on the drive," the authors say. "Though this may repair the file system, it permanently destroys the data."http://www.darkreading.com/document.asp?doc_id=153090&f_src=darkreading_section_296
