Today I set out to see if Windows 7 would run MS Flight Simulator X any better than Windows XP did. I found that Windows XP on my Mac Pro (Dual Xeon with 10GB of ram) ran very sluggish. Partly because Windows XP (32-Bit) would only recognize about 3.5 Gig of the 10GB of ram that was installed in the machine. So since I recently got a Technet subscription (I seem to have to do a little more Windows stuff now at work, so thought I might as well learn what I have to manage) I downloaded the Windows Ultimate 7 to see how it would perform before going out and buying it. So I did a Time Machine backup of my data on my Mac Pro and then inserted in the Windows 7 disc and hit the “go”. It took a couple of hours to do the install, patch it, update boot camp stuff and install Flight Simulator. Once it was installed I was impressed that it actually performed much better than it did on Windows XP. I could actually turn the graphics stuff up on it and almost run it at 1900×1200 with out any jerking around. I then did a couple of flights and then it was time to boot back in to MacOS to get some real work done. This is when I about lost it..

See when I booted windows 7 it had found the other 3 data drives that were all HFS+ drives in my Mac. It decided to assign a drive letter to them all. I went in and un did that as I did not want Windows to touch those drives. I thought all was well, until I booted in to MacOS. When I logged in, it told me that the drives could not be read, and it couldn’t find my home directory (which was one of those drives). I was PISSED! So the first thing I did was pop up the disk utility and this is what I saw (minus the 2 1TB seagate drives):

What pissed me off was that every partition I clicked on, it said it was an MS-DOS partition. Surely Windows didn’t screw around and format all my drives.. I was at a loss, all my data was on there, 20,000+ pictures, all the video I was working on, everything… So I decided to see what I could see from the command line. So off to the command line, and I ran the “diskutil list” command and saw this:

Yup, Micro$oft had screwed with my partitions.. So I was hoping that maybe it just changed the partition type and my data was still there. So I poked around to see if there was a way to change the partition type. In the gui tool, the only way to do it is to “format” it over, which meant I would loose everthing, and I didn’t have any backups, as the disk2 in there was my Time Machine backup drive. So thinking to my Solaris side, I knew there was a program called “fstyp” that would tell you what a particular disk slice was formated as. So I gave it a shot and MacOS has that program:

So I ran the fstyp util againest one of the slices, and it came back saying it was HFS… Hot diggity dog.. Maybe my data is still all there.. So I did a mount on it as readonly and it worked. I could see all the data on the drive. So I immediatly started copying data from the drive to an external USB drive (the first 1TB seagate drive in the picture above). But the problem now was, I had 3 x 500GB harddrives of information. The 1TB drive only had about 400GB free. So off to Best Buy and I picked up a Seagate 1TB Firewire drive. Brought it home and mounted up the other partitions and started copying the data. It has been going on for about 2 hours or more now on the copy. I will say that the Seagate Firewire 800 drive is spanking the ass off of the Seagate USB drive.

Once I have backed up all the data.. (Hint use the ditto command) I will see if there is a way to change the partition type with out reformatting the drive. If there isn’t then I will have to reformat and then ditto the data back on to the Internal drives..

Hopefully this will help some one else if they get the same problem, and it (MacOS) tells you “you must initialize the drive”. DONT. Tell it to cancel and then you can save your data.. If you initialize it, you may end up loosing all your data.

—Update

As I waited for the data to finish copying I decided to test some stuff on my time machine drive. I read a bunch on the GUID labels that are on the disks. Using the gpt command i did a listing of the GUID info for the drive. Using that information I deleted the index 2 and added a new one with the Apple HFS GUID label:

In the above, you can see I removed index 2. As soon as I did that, this window popped up:

I just selected ignore on it. Then went on to put in the new GUID label which was the third command in the shot above. The numbers (409640, and 976101344) are taken from the line that has index 2 on it above. You MUST use the exact same numbers, otherwise you are going to change the partition size and may corrupt your data. The value after the -t is the GUID value for MacOS HFS (HFS+), which I found on http://en.wikipedia.org/wiki/GUID_Partition_Table, you can also see that the one that was listed before I removed it was a Windows Basic Data Partition.

As soon as I hit enter on the gpt command to add it in, the gui disk utility immediately changed and now showed me my data was there. It also mounted the disk like nothing had happened.

I am going to wait till the copying is done and then do the other two drives and then I should be back to where I was before I installed Windows 7.

Just released, another exploit to Internet Explorer 6 & 7, that allows “hackers” to install software on your machine… What do the major Antivirus people say:

“To minimize the chances of being affected by this issue, Internet Explorer users should ensure their antivirus definitions are up to date, disable JavaScript and only visit Web sites they trust until fixes are available from Microsoft,” Symantec said.

How many mom and pop’s out there even know how to disable java script, and only visit sites they trust? Let alone make sure their antivirus definitions are updated. I have seen some virus trick Symantec’s AV in to thinking the definitions were up to date, and then I go to find hundreds of virus’ on my parents computer. This is just another reason why building the web browser in to the OS is a bad thing and why it should be sandbox’d off in to its own little area.

Has any one else seen this problem? Using a MacPro with Snow Leopard 10.6.1 on it, and it seems like everytime I go to shutdown the Mac (using Finder and holding Alt and clicking on shutdown) it shuts down, but then a second later it starts back up. (almost as if it was doing a reboot instead of a shutdown. When the login screen shows up, I click the shutdown and it shuts down and doesn’t restart. Any suggestions?

I received my copy of Snow Leopard today from Apple. They overnighted it and fedex was kind enough to call and tell me they tried to deliver it but was unable to. I stopped by the Fedex depot on the way home and picked it up. I decided to load it on the Laptop first because I have heard of some problems with Adobe Photoshop Elements (which I run on the Mac Pro desktop).

So what are my thoughts:
1. I think Apple shipped some faulty DVD’s. Everytime I put it in my MacBook Pro, it would try to read it and then it would eject it. I put it in the MacPro desktop and it came right up. So back to the MBP and it continued to just eject it. I then attached an LG External USB DVD drive, and it seemed to have some problems reading it on there. I then did the Apple Software update (there were a couple of Security alerts available) thinking that may help. Didn’t appear to. Then all of the sudden it loaded the installer. After an hour later and 2 reboots Snow Leopard was installed via the USB drive. They still need to work on their installer, it set at the “Time Remaining : Less than a minute” for over 10 minutes.

2. The initial startup seemed to take some time, but have not tried rebooting it yet.

3. The Finder seems extremely faster.

4. It free’d up almost 10 gig of disk space for me. I started the install with only 17gb free. After the install I now have 27.11 gb free.

So far I havn’t tried any of the other apps I use, but Adium X 1.4b9 seems to run well. I also like the new Expose, seems to organize stuff a little better. Will have to see what else has changed.

I finally got time again to start playing with Sun Ray 5 Early Access software. Now my current setup probably should not be used for any type of test more than simple single/dual user testing. But I did not want to test the software on the current working server. So I decided to install it in a VMWare image on my Mac Pro. The Mac Pro is more than suited to handle it and had plenty of free memory/processor/storage to use so there was no contention (I gave the VM 4 processors and 8 gig of ram)..

The kicker was getting VMWare Fusion to actually allocate the network cards the way I needed them. I gave the VM 2 nics (the Mac Pro has 2), however the only options that VMWare Fusion let you do is NAT, Host-Only, and Bridged. None of which will work if I want a private network for the Sun Ray’s. To fix this you will need to go and edit some files that VMWare Fusion uses. What I had to do was the following:

1. Open up the Terminal app
2. Edit the file /Library/Application Support/VMware Fusion/boot.sh

3. Comment out the following line:

And then add 2 lines directly below that line, which tells vmware to bind the en0 physical device to the vmnet0 virtual device, same for en1 to vmnet2. Note you can not use vmnet1 or vmnet8 as those are for NAT and Host-only connections.

Once done, do the following:

Now go in to your Mac System Preferences and configure the second network card for a private subnet (i.e. 192.168.128.0/24, and set the IP to be something like 192.168.128.254).

Now make sure that your VM is NOT started and is in a powered off state. Go in to the VM and under the settings for that VM add another network adapter, make sure it is selected as “Connected” it doesn’t matter what the device is configured to as we will change it later to an option that is not shown in that list.

Now you need to change the .VMX file so that it can use the new network device. So go in to the directory where you have your VM’s at and then cd in to the machine.vmwarevm directory (For example mine is called SolarisDev.vmwarevm)

Once in there you will need to edit the vmx file, mine is called SolarisDev.vmx. The first thing we are going to change is the ethernet0.connectionType property. Right now it could be any of the ones listed (host-only,bridged, nat). But we are going to change this to “custom”:

Next find the entry for ethernet0.vnet, if it doesn’t exist create it and make it look like the line below. If it does exist and doesn’t match that below, make it match that:

Now we need to do the same for the ethernet1 entries. The only difference to what is above is vmnet0 changes to vmnet2. Once the changes are made you can save the file and start up your Solaris VM. Now what ever network is on your en0 connection on your Mac should be what is connected to the e1000g0 network on the Solaris side. I used the e1000g0 as the “public” side of the Sun Ray server. The e1000g1 interface will be what ever is connected on the en1 connection on the Mac side. I used this adapter for the private Sun Ray Lan.

You should be able to finish following the instructions on the Sun Ray wiki now and get everything configured.

To test the soft client, I set up LAN Connections on the Sun Ray Server:

I then installed the soft client in another VM on the same machine that only had access to the public network. You then can tell the soft client what the IP of the Sun Ray server is and it will connect. Pretty darn cool that the soft client works with minimal config.

This can probably be done on a MacBook Pro as well, if you use the wireless connection as the public side and the wired as the private side. Nice way to do a little demo in one computer.

For reference here is what my network section of the .vmx file looks like :
