Upgrade Crucial C300 firmware on a MacBook Pro

I just got a Crucial C300 SSD to plug in my Mac. And it came in revision 02 ; but the latest bug free firmware is revision 07.

To upgrade, just go to the Crucial website and get the “C300_FW0006.zip” archive. Unzip and burn the ISO file. Reboot, use ‘alt’ to drop to the boot selector and select the CD drive ; it appears as “Windows”. Let the process find your drive and upgrade the firmware to 06. When done, reboot.

Now, get the “C300_FW0007.zip” archive and replay the previous scenario.
After a few seconds, the SSD has the latest firware installed:

C300-CTFDDAC256MAG : Capacité: 256,06 Go (256 060 514 304 octets) Modèle: C300-CTFDDAC256MAG Révision: 7

So easy! And so nice it works on the Mac!

Run OpenBSD from USB on MacBook Pro

I own a MacBook Pro (5,5 with Core 2 Duo) and wish to test running OpenBSD on it. But I don’t want any impact on my OS X installation. So I’m going to install and run OpenBSD from a USB stick.

What I used

  • A mid-2009 MacBook Pro (MacBookPro5,5);
  • A Corsair VoyagerGT 16GB;
  • An OpenBSD 5.0 (/snapshots/) CD;
  • The rEFIt 0.14 boot selector.

Fast sleep on Mac OS X

By default, my MacBook Pro goes into deep sleep (hibernate) mode when I close the lid. This is nice but I have 8GB of RAM and it is quite a slow process. Furthermore, I never went out of battery during a whole sleep process. So I’m going to avoid dumping my whole RAM content to the SSD disk and save of bit of it:

# pmset -a hibernatemode 0 # rm /var/vm/sleepimage

Should I want to re-enable hibernate mode, I’d run

# pmset -a hibernatemode 3

This enables going in sleep mode in 2 seconds, rather than a minute… w00t!

Toshiba MK1059 GSM in MacBookPro5,5

I had issues with my Seagate Momentus 5400.6 500GB… It felt very slow… But it also only had 10% free space left…
It’s been two weeks I’m trying to work on this… Defragmentation, Onyx on the system… Maybe it’s just to full… Thank my Sanyo HD1010 for that… So let’s go for it… upgrading to 8GB of RAM (from stock 4GB) and to TOSHIBA MK1059GSM 1TB.
