Fujitsu Europe is now offering the optional fitting of a free fall sensor (FFS) to its laptops to protect hard drives in a fall.
The sensor uses the time before an impact to better protect the hard drive against head crashes and data loss.
Ramp load technology moves the read/write head from the medium onto the ramp while the drive is in free fall, thus preventing the head from striking the medium.
The free fall sensor self-activates for falls from a height of about 20cm or more. It also protects the data being processed and damaged in the event of falls from lesser heights.
The free fall sensor is not deactivated until the system is motionless and on the ground, and the data remains available in the drive’s buffer memory.
Users can then take up the read/write process where they left off and resume their work without delay.
Fujitsu is offering this new protection mechanism as an option to all SATA-hard disc drives of the MHWxxxxBH-series with a capacity of 40 to 160GB. It will also be included in new models.
IBM also offers sensor impact protection on some of its laptop models.
