Crucial MX100 256GB - sudden random freezes

Hello I have a MX100 256GB as a system drive. So far I had no issue with it except for a single event when SSD became invisible to the system and required a power cycle to appear again. I have MSI Z77 Mpower motherboard with up-to-date BIOS, latest Intel RST drivers and MU02 Firmware. 

 

Suddenly yesterday my computer froze while idling in desktop with no particular reason. There was nothing in the Event log, so I came to conclusion that the problem is with the SSD. The freezes were occuring randomly, but usually within couple of minutes after booting up PC. I searched the internet and forums and finally uninstalled Intel RST which apparently solved the issue. At least there are no freezes so far.

 

What I don´t understand is how it could work without problems for such a long time. There was no recent software installation, no updates, nothing new at all. 

Also the AS SSD benchmark and Windows device manager shows iastor as an active driver. I thought that if I uninstall Intel RST it would switch to msahci. They can work separately? 

 

What should I do now, should I try to reinstall Intel RST, is there any benefit doing so?  Thanks for the help.

Re: Crucial MX100 256GB - sudden random freezes

Seems it didn´t fix the issue at all. The system keeps randomly freezing. I have restored the system from the restore point, tried CHKDSK, checked all running processes and services. Sigh, I really need that PC right now. Smiley Sad

Re: Crucial MX100 256GB - sudden random freezes

Freezes are definitely caused by SSD, I cloned SSD to my old HDD and everything works Smiley Sad

Re: Crucial MX100 256GB - sudden random freezes

Ok, I tried pretty much everything. It definitely seems to be problem with the SSD itself. I saw a pattern in the freezes. It looks like there is a problem with writing from the cache. It seems as if the drive locks up after a certain amount of writes, or if it tries to flush the cache at the shutdown. If I did mostly read operations the system seemed to be fine after a couple of hundreds megs of writes the drive locked up. It also froze at the shutdown, right after I heard clicks from my HDDs as they moved heads to parking postition.

After cloning the SSD to my old laptop HDD the PC works without freezes, (though it is slow as **bleep**) Smiley Tongue  I´m going to RMA the drive today. I just hope the tech guys at the store will identify the SSD as faulty, so I can get a new one. The speed of the SSD is unbeatable, though this is like third time in a year and a half that I have to deal with SSD issues and data loss. At least I learned how to do a proper backup - the hard way.
