Re: Feedback Thread Firmware M0CR070 for the MX300

This firware is an abslute disaster for me, it's killed my RAID 0 array and now I cannot access my data.

Storage Exec updated it automatically and the drives immediately became slower and inaccessible after a few minutes of operation.

I uninstalled my RST drivers and reinstalled them, no joy. tried around 12 version of Intel RST drivers, all experienced teh same issue. Re-installed windows, same issue. had to rebuild the array and recover the partition around 4 times.

I need to roll this firmware back. how do I do that?

 

NO-ONE SHOULD USE THIS FIRMWARE!!!!

Re: Feedback Thread Firmware M0CR070 for the MX300

Understandable that you are upset. But the firmware seems to run just fine for other users, incl. myself.

Therefore I can't agree with your warning.

That is very unfortunate.   Any time you use any type of hardware RAID you must be very careful especially with RAID 0.   RAID controllers can be very picky about the drives and a change in firmware may cause it to be identified differently by the RAID controller.  Or perhaps your MX300 had a problem that went unnoticed until the firmware update which revealed it causing the RAID controller to break the RAID.   Besides firmware updates are always risky.   What you experienced could potentially happen with any brand of drive.

 

Verified working backups are even more important when using SSDs than ever before.
