In august 2012 I bought two crucial m4 ssd's, installed both of them and the performance was surprisingly amazing but after 8 months of use, the crucial m4 installed on the Mac mini went crazy, won't boot up correctly, applications wouldn't load. I couldn't even do the firmware update, sent to RMA, and I'm waiting for the replacement.
Now, 10 months after I have bought the ssd's, the one on my Macbook pro is showing the same problem as well. It refuses to boot up, it stays on the white boot screen with the apple logo for minutes, without any signal of progress.
The firmware is the 309, I will try to do the firmware update as soon as possible and show you the results, but I guess I can predict what is going to happen.
I'm really disappointed. I wish I could say I can trust Crucial M4, but I guess it's to time to try another SSD.

I'm not sure if the newer firmware is going to help, although perhaps no harm in trying, but most people seem to have good results with either 0309 or 000F firmware. In fact there are some that would say that those are the most stable firmware releases for the M4.
Do you have TRIM enabled in your Mac Mini?
One thing I'd try would be an ATA Secure erase like this:
I suspect that might have better results than a firmware update.
Before starting the secure erase:
a. Make backups.
b. Make sure you have recovery media or your Mac supports Internet Recovery.
You will have to recover with Time Machine (or whatever your prefered method) after the secure erase.

I've never booted a Mac with Parted Magic, but provided you can get it to boot, that might be the best way.
However I have booted a MacBook Pro 13-inch late 2011, with Gparted Live which I booted from an EFI bootable USB stick.
Here is an example using Gparted Live to secure erase from command line:
Search these boards for more info on using ATA secure erase if you need it. If you go the Gparted way you might have to modify the linux kernel arguments in /EFI/boot/grub.cfg
This was the case with my Macbook Pro with Intel HD Graphics 3000... perhaps there might be different problems (or no problems) with Macs with NVIDIA graphics.
In any case, the change I needed to make was (old):
linux /live/vmlinuz boot=live config noswap noprompt toram=filesystem.squashfs ip=frommedia nosplash i915.blacklist=yes radeonhd.blacklist=yes nouveau.blacklist=yes vmwgfx.blacklist=yes
New, modified line removing the i915.blacklist (as an option remove the other blacklists too):
linux /live/vmlinuz boot=live config noswap noprompt toram=filesystem.squashfs ip=frommedia nosplash
Note: I didn't run Secure Erase as I was using Gparted for experimenting with some else (planning to dual boot), but at least Gparted Live can be booted (on some Macs at least) if you can't get Parted Magic to work.
