For about 2 months, off and on, my Mac Pro goes crazy reading or writing to the hard drive.   This makes my Mac Pro feel like an old computer, even with 4 cores under the hood!

Most of my Googling, referred to a spinning wheel related to Safari.  No solution until now!

1. Open Applications\Utilities\Terminal to type some commands.

2. To find out which applications are taking up your CPU time, type:

top -o cpu

3. At the top of the list, should be the application taking your CPU time.  In my case it was mds.

4. To kill the process, type:

sudo killall mds

<type your password>

After that, my disk drive stop making all that noise!  What a relief!

While you’re at it, you might consider disabling Spotlight.  I don’t understand why it make my hard drive go crazy if it has had so much time to create an index for each hard drive.

To disable Spotlight, type:

sudo mdutil -a -i off

What Failed, sometimes Me

Wrong Top Sort

Along the way I tried finding the process that used the CPU the most.  I had accidentally set top to sort by process id (pid) so it never gave me the correct answer.  Looking at the man page, the above top command with -o cpu always sorts by CPU usage.

Iotop Error

After searching online, I found out that Linux uses iotop to find the process using the hard drive most of the time.  Fortunately, under the Mac OS X, it also exists.   But when I ran

sudo iotop

for a while, it would insert an error and prevent the proper culprit to show up in the list.

dtrace: error on enabled probe ID 5 (ID 19321: io:mach_kernel:buf_strategy:start): illegal operation in action #3 at DIF offset 0

Miro – Internet TV

Miro

Miro is great because you can take it with you on your laptop, unlike this TV.

I’ve been using this app off over the past 6 months. This TV app is great when downloading various video RSS feeds, such as CrankyGeeks and Linux Journal podcasts.

The download speed of these podcasts is faster than iTunes!

VMware Server 2.0 RC1 is ready for download!

  1. Register for a free key.
  2. Install VMware Server 2.0 RC1.
  3. Create a new VM.
  4. Install any operating system.
  5. Boot your fresh, new VM!

Bringing up Xubuntu has been easy, as in previous versions of VMware Server.  Best feature is moving USB 2.0 devices into the VMware VM.  Tranferring files should be faster via a USB flash drive.  Might be placing my iPod Touch iTunes there.

The new interface needs some time to get used to it.

Download – Big download about 550 MB.
