TRIM disabled on Crucial C300?

Just got a new Dell M4500 here at work and finished out the Windows 7 64 build on a spindle drive. Ordered a C300 256GB (latest firmware, 0002) and imaged it using Acronis True Image, copying all the partitions as is (even the 750mb Recovery Partition). Swapped out the drives. It's working fine, but PC Wizard is saying TRIM mode is disabled. How can I verify this and turn it on if need be? It's running in AHCI mode.
 
Trim works under BIOS IDE mode as well as BIOS AHCI mode, but both are dependent on the operating system's "driver". Trim is simply a feature on an SSD. This feature is kick started (for lack of a better word) on the SSD by the command being sent from the OS "through" the driver, to the SSD. If the driver does not pass the trim commands, the SSD will never initiate the trim function internally. Microsoft's IDE "and" AHCI driver both support trim command passthrough. Intel's AHCI driver also supports trim and might be 2% better (at best) overall than Microsoft's AHCI driver.

C300 definately supports trim (alll released firmware versions), so whatever you use that says it doesn't, is wrong. Again like I said though, supporting trim is not the same as "performing" trim because it's dependent on the driver.
 
So is it best to just wait and see if performance changes at all? I mean, is there a way to verify that Windows is running TRIM or no?
 
Here's something to think about. When you originally installed windows - you did it on the mechanical, rotating hard drive. When you imaged that drive to the SSD all the drivers and settings for the old HDD are now trying to work with the SSD. Not only that but the issue of drive alignment comes into play... you may want to reinstall windows directly onto the SSD. I'll bet everything will work OK then.

I'm not saying it's not working, I just don't know if it is. Regarding drivers from the old hard drive, I've imaged systems before to different drives and each times Windows installs a different (appropriate) driver for it, swapping out the old one.
