10. OCZ Technology
The once mighty pioneer of solid-state drive technology came crashing down this year. OCZ filed for Chapter 11 bankruptcy protection last month and was on the verge of liquidation before recently being acquired by Toshiba for a paltry $35 million. So how did it come to this? The company fell behind in the SSD market and was forced to scuttle its memory and DRAM products. But the big controversy involved OCZ's financials; after several shareholder lawsuits hit the company last year, OCZ was required to restate its earnings for several years dating back to 2008.
