Intel fixes SSD 530 wake hang bug

Bit Tech noticed Intel has issued SSD Toolbox 3.1.8. This new release addresses a bug in the SSD 530 series that results in hanging on resume from standby, you can download the fix over here.
The flaw, which affects all Intel SSD 530 Series drives, affects the drive when addressed using Aggressive Link Power Management (ALPM) - a feature of Advanced Host Controller Interface (AHCI) SATA devices which allows the drive to enter a particularly low-power state during idle periods while returning to full activity i less than 10 microseconds during a 'partial' sleep state or 10 milliseconds during a 'slumber' state.

With very little effect on performance, ALPM is a great feature - except when, as with the Intel SSD 530 Series, it doesn't quite work. A bug in the firmware across the whole family of drives leads to a small but annoying chance that the drive won't wake up when it's supposed to - leaving the user forced to power their system off and back on again to regain access to their data.
