Crucial: The need for a firmware update!, 8 July 2012
I bought one of these for my Windows 7 Ultimate PC about 7 months ago (13/11/2011). It worked just as I had hoped and my Windows loaded in a flash and all my programs seemed more responsive.
About 7 months later my computer began to freeze for no apparent reason, usually when I was surfing the net but not always then. This problem slowly got worse until the computer would not work for more than about an hour without freezing. I tried everything I could think of to track down the problem but to no avail. I used the windows repair disc, I checked the CPU core temperatures, I rebuilt the Master Boot Record ( this because one of the fault messages said the there was a problem with the MBR).
I had noticed on one of the many occasions that I had to restart the computer that the Crucial SSD appeared to be missing from the list of hard drives but it always came back after a while and I began to suspect that I had a computer overheating problem. It was nothing of the sort!
I made the decision that the fault was beyond my understanding and that I would take the computer into my local computer repair shop on Monday morning. I continued to research the problem over the weekend by searching for any comments by others on freezing SSD's but none of the many problems appeared to apply to me until I searched for the problem with this particular SSD and amongst the very many hits I chanced on a comment about this drive that solved the problem!
The comment I found said "After 5000 hours of life the Crucial M4 SSD 128GB 2.5 Drive will cease to function after about an hours use, this can be cured by updating to the latest firmware '000F' which can be found on the Crucial web site."
I had been using my drive for seven months before the freezing began; 210 days or 5040 hours.
I went to the Crucial web site, entered the name of the SSD and found the appropriate firmware upgrade and followed the instructions. They were quite easy to follow with the only odd moment being when the updating program said the I did not have an SSD that needed updating, when I took no notice of this and told the program to continue it went ahead and found my SSD and updated the firmware to the latest '000F'.
When I restarted my computer all was well- I had lost no data and the computer has worked perfectly without freezing ever since.
In conclusion: This is an excellent drive but you need to be aware of this potential problem in the future.
