Crucial Provides a Firmware Update for M4 to Fix The BSOD Issueby Kristian Vättö on January 14, 2012 3:22 PM EST
Last week, we wrote about the BSOD issue that Crucial's M4 SSDs were experiencing. After 5184 hours (yes, that's the specific number) of active use, the SSD started to cause blue screens of death (i.e. BSODs) every hour or so. Originally, the fix was scheduled for next week but fortunately Crucial was able to release the firmware update yesterday. The firmware version is 0309 and can be downloaded here. It's recommended for all Crucial M4 SSDs, even if you are not experiencing the BSOD issue as it will prevent it from happening.
The earliest reports indicate that the update does fix the BSOD issue, although it will take at least several days before we can be sure of that. User Vivio at Crucial forums has already run benchmarks and the update appears to be a pure bug fix, as the performance is the same as with the older 0009 firmware (see Anand's review).
