Measuring I/O Latency with BAM
Has this ever happened to you? You have a storage device that fails at a customer site, but when you bring it in to engineering it passes all of your tests. You try to tailor your tests to closely simulate the customer environment, but just can’t seem to duplicate the failure in your lab. Read the rest of the article here.

Ask Dr. SCSI – DOD disk erase/sanitize standards?

Q. “I need to erase some disk drives to DOD standards. What are these standards, and how can I erase disks correctly and thoroughly?”

A. The DOD standards for disk erasure can be found at: http://www.dss.mil/isec/chapter8.htm

The bottom line for disks with data classified lower than Top Secret is that they may be erased by writing a data pattern to all disk blocks, then writing the complement of the first data pattern to all blocks, then writing random data to all blocks. An STB Disk Manufacturing Module (DMM) test sequence file may be downloaded here : http://www.scsitoolbox.com/downloads/DMMDiskScrub.zip – download it and you can erase multiple drives simultaneously and quickly with DMM.

What about disks with Top Secret or above data? Magnetic degaussing or physical destruction is the only approved solution.
