Micron C400/Crucial m4 not working with SATA 3

I have a 2011 17" Macbook Pro 8GB. Upon installing OS X on the drive, which replaced the stock hitachi 7200rpm drive, I get 20-30 second pinwheel freezes during which time the drive (and OS) are unresponsive.

I have tried SMC reset, PRAM reset, turning off SMS and hd sleep, and nothing has resolved the issue.

Apple, please fix this.

many, Mac OS X (10.6.7)

Make sure you have Lion 10.7.1 update,

Make sure you have the recent firmware update for the SSD.

Yeah, I have the Crucial M4 512 SSD and a 17" 2.3 Quad i7 MBP. The drive doesn't work at all connected to the SATA connector. Works great through the USB or Firewire ports. The drive is running the most current firmware which is 9. I really want to use it and not return it. 😟

your MBP is Sata2 (3GB/s), Crucial M4 has Sata3 and is downwards compatible to Sata2, so it should connect with 3GB/s, when connected to Sata, which is when built in as a replacement for the internal HDD.

USB on your system is 450MB/s, Firewire is 800MB/s. I do not know that the M4 connects to that.

Although Trim has nothing to do with speed, but with longevity, it is better than Garbage Collection, thus I advise you to activate Trim (the M4 has Trim support inside).

I've adapter for USB2 to sata and FW800 to sata, with this interface i've not problem!

when the ssd is installed inside MBP the system slows down and freeza.

Now I have activated the TRIM and the hibernate mode set 0

Test in progress...

Wonderful disk.

I'd build it in, should work.

Easiest way to do it, assuming your system is running well on the standard harddisk:

Make a backup of your whole system on an external disk, or even better make a clone.

Then connect the M4 with the adapter, and make a clone of your internal disk with Carbon Copy Cloner onto the M4: it will make a bootable clone.

Test it by starting up from the M4, while it is still outside.

When everything is OK, replace the internal HDD with the M4.

Start from the M4, repair permissions, set hibernatemode 0, install Trim. repair permissins again.

NEVER use Defrag, cleaners, antimalware, keepers, antivirus etc. It is done in the OS daily, weekly, monthly.

And have fun, even with Sata2 it is wonderful, I know I have it too on my late 2009 MBP.

after varied test the system has given back a serious error, File system ERROR!

now I will try to install the SSD on a macmini intel 10.7.2 to test the stability...

I do not know where to blink the head!!!!!!!!
