Some versions of the Crucial M4 Solid State Drive (SSD) may start to become unresponsive. The system may appear to hang or run very slowly, sometimes at regular one hour intervals.
The cause is a firmware problem which causes the drive to become unstable after 5184 hours of power-on operation. The drive may also sometimes not be detected by the system BIOS when the system is turned on.
Even when the drive has been detected and appears to have recovered, the drive may experience performance or detection problems after every subsequent hour of use.
The root cause is a problem with the drives SMART monitoring and management system which encounters a problem after 5184 hours of use.
Install the latest drive firmware to correct this problem.
The problem has been seen with Crucial M4 SSDs with firmware versions older than 0309. Firmware 0309 provided the first fix for the 5184 hours issue, however we recommend that any drive with firmware 070H or older should be considered for a firmware update, as this also resolves some problems with Windows 8. Firmware 070H was released on 04/02/2013.
How to Check the Number of Power On Hours
Use the Stone Smart Gather tool, or use a utility such as CrystalDiskInfo Portable Edition.
The Raw Values column can be changed from Hex to Dec via the menu.
