I have a Crucial M4 SSD that is 2.5 years old and still in warranty. The drive has a nasty habit: If it loses power, it disappears from my laptop. Crucial has a procedure for bringing it back to life prominently displayed on its support site: 1. Remove the drive from my laptop 2. Connecting it to the power of my desktop for 20 minutes. 3. Remove power and wait 30 seconds. 4. Repeat step 2. http://forum.crucial.com/t5/Solid-S...quot-disappear-quot-from-my-system/ta-p/65215 The procedure works. Unfortunately, the result is often a corrupted windows installation. Crucial has issued bios fixes attempting to mitigate the issue, but if anything it appears to be getting worse: it has happened 3 times in the past 4 months or so and even at that, the drive has only been in my system for half the time! If you google "ssd disappear", the majority of the hits you get are about this issue on the M4. Crucial won't replace it because they say it is normal(!?): Digging further, though, they may not be wrong, but that is not an easy question to answer: Googling "kingston ssd disappear", aside from links where people say they are going to replace their disappeared Crucial M4 with a new Kingston, there are some that describe the same issue happening with Kingston: http://www.hardwarecanucks.com/forum/storage/48038-ssd-loses-connection-randomly-what-do.html This involved a "Sandforce" controller and the forums suggest it was a bios bug that was fixed, but nevertheless took down the company: http://en.wikipedia.org/wiki/SandForce But the M4 doesn't use the SandForce controller. Worse, this paper implies that Crucial may be correct: http://www.extremetech.com/computin...ing-drive-are-power-outages-killing-your-ssds I quote/link the article about the white paper instead of the paper itself because it is a bit over my head. I really don't know what to do here. I have a $400 SSD that I'd rather not have to throw in the trash, but I also would rather not waste a day re-installing windows every time a minor issue causes it to disappear and become corrupted. Anyone have experience with this issue? Comments? Recommendations?
