When to run a low-level format on an Intel® Solid-State Drive?

If one or more of the following scenarios are met, then a low-level format should be run on an SSD:

  • Operating system experiences slowness or freezing
  • Before reinstalling an operating system
  • If the Intel® SSD toolbox fails the read or write diagnostics
  • If performing a regular format or partition on the SSD results in an error
  • If any other data integrity issue is suspected
  • There are several free tools which can be used to run a low-level format:
  • Secure erase included in the Intel® SSD toolbox (this option will only work on a non-bootable secondary SSD)
  • HDAT2*: www.hdat2.com
  • Killdisk*: http://www.killdisk.com
  • Dban*: http://www.dban.org
Note A quick format done through Windows* sets up an empty file system on the disk and installs a boot sector; the full format in Windows does the same as a quick format and will scan the entire disk for defects. A low-level format, on the other hand, queries each cell if it has been written to and then will write a zero to this cell. This may also be referred to as 'zeroing' the drive or 'flushing' the drive.
