CWmike writes "Intel has pulled a firmware upgrade it released on Monday for its X25-M consumer solid-state drives after users complained that the software caused crashes. The company on Monday made available a software package called SSD Toolbox to monitor and manage the performance and health of X25-M SSDs on systems running Windows 7. The package included a firmware upgrade and software called SSD Optimizer that included diagnostic tools to help keep the Intel SSD running at high performance. 'We have been contacted by users with issues with the 34-nanometer Intel SSD firmware upgrade and are investigating. We take all sightings and issues seriously and are working toward resolution. We have temporarily taken down the firmware link while we investigate,' an Intel spokesman said in an e-mail. The spokesman declined to comment on when the company would issue updated firmware."
