Mac Pro :: How To Build RAID0 Boot System
Nov 11, 2009
I have a Mac Pro 2008. I just got my second Crucial 256 gig SSD. Wanna make it a Raid 0 with my first one. Here are my thoughts.
Process 1:
1. Use disk utility to restore image of original Crucial 256 SSD to external USB drive
2. Boot up with SL DVD
3. Build Raid 0 using two drives. (do I need to 0 out?)
4. Restore image to Raid 0
5. Boot
Process 2:
1. Boot off DVD
2. Create Raid0
3. Use SL to restore backup from time Machine to Raid 0
4. Boot

I'm planning to replace my boot hard drive with a pair of RAID0ed SSDs. In order to familiarize myself with certain techniques I have build a software RAID0 from two 160 GB Maxtor SATA I hard disks. That went pretty much without problems. The two HDs are now sitting in position 1 and 2 in my Mac Pro.
The problem arises when I try to clone my boot drive onto the new RAID 0 drive. I was using disk utility and got an error message. Then I thought my fault was using disk utility from the HD which I wanted to clone and booted from the Leopard install disk. I then used disdk utility from that source to clone the HD boot drive to the RAID. Again I got the error.
What is going wrong? Do I have to approach this completely different?

I want to reformat and install SL fresh and am getting an error when i use Disk Utility (booting from SL DVD) to delete the RAID0 config. The error is "invalid request".
I have 4x640 in Software RAID0 that i boot from.

I've got a 2 drive 640GB Black Caviar RAID that I want to set up as just an OS and apps boot drive.
I realize larger block sizes have more through put but waste disk space, and smaller sizes save space but are less efficient.
My user folder (mail, media, itunes, video, docs) will be on a separate drive.
(1) So how do apps and OS files load at boot time and runtime?
(2) If apps like CS4 are large apps does it not make sense to set 256K as the block size?
(3) Or does OSX use many small files thus needing a smaller block size?

As we discussed in other threads it could be particularly advantageous to use SSD RAID0 arrays for dual or even multiple booting. With a decent amount of striped SSDs the idea is to run all your operating systems and applications with high speed. At least that is the theory. To test the idea I have decided to use two Maxtor 160 GB HDD in a very basic dual RAID0 array configuration for booting OS X and Vista-64 in AHCI mode.
Here we go:
First thing I learned is that you have to partition the HDDs prior to building your array.
Second thing I learned is that you have to keep it all in HFS+ to make it work.
So now I have used disk utility to create two equal size partitions in HFS+ with GPT on both HDDs.
Next I fused the two lower partions together for a first RAID0 array named 2R-Leo. Format is still set to HFS+ and RAID0 mode is selected.
Then I fused the two upper partitions together for a second RAID0 array named 2R-Vista. Here format is also set to HFS+ and RAID0 mode is selected.
With that done I exited the disk utility to get a fresh start on it. I then entered disk utility again.

I just received my Macbook Pro today, pretty excited. I need to put windows 7 on this machine and I was wondering if someone could tell me the best RC version to put on. I actually have a copy of the x86 7100 build but I am under the impression that a 64 bit version would be better. Am I correct in thinking this?

I'd like to build a security system for my office, using my 1Tb Time Capsule and connecting wirelessly to it, a couple of video cameras. Ideally, I'd like to allow the video camera to take shoots each while, and save thos on the TC hard drive. Anybody knows if that is possible?

I've been reading this site for a while now, first time I'm posting. I recently purchased 8 GB of RAM for my 2010 13" MBP. There are two 4 GB DDR3 PC3-10500 1333mhz sticks. When I install them in the laptop my computer does not get past the apple logo boot screen (the spinning disc freezes). However, I can boot into Windows (boot camp) without issues.
Also, when I pair either of the 4 GB sticks with one of my old 2 GB stock sticks the laptop boots up fine in OS X. The system profiler registers it as 6 GB of 1067 mhz RAM (the stock sticks are 1067 mhz)

So I finally got Windows 7 64bit installed on my MBP 2.33 machine.
However, from the guides, I should just insert my leopard disc and it should run. This is the thing, I don't know where my leopard disc is (i've been moving a lot lately due to being unemployed) and its either lost or packed away somewhere. I have a backup copy on my time machine drive and haven't tried that yet. I downloaded a 2.1 extraction and burned it to CD though. I inserted the CD and I can see in windows 7 three applications. One is Windows XP, the others are Windows Vista 32 and Windows Vista 64. I click the Vista 64, but nothing happens at all, and no drivers are isntalled.

I'm having a hard time deciding what to do with my two open HDD bays in my Mac Pro.I know I want to add more storage, but I'm not sure if I should use Raid0 or not.I store most of my media on a server but wanted to store the following in my MacPro and would need more hdd space.Bootcamp - obviously can't store in serverScratch drive - would write handbrake encodes to this then transfer to serverIn all I'll need around 1.5tbI already have a 1.5tb drive and would only consider buying another to put them into raid0. Should I bother with raid0 for the increased speed or just use the 7200RPM 1.5tb drive I already have?

I am thinking about adding a pair of Sandforce SSD drives in RAID0 on my Mac OSX device. Since OSX does not support trim I am dependent entirely on over-provisioning and idle garbage collection to keep SSD drives in good shape long term.
My question is if you use two drives that support BGC in a software RAID0 configuration does the BGC still work as effectively as with a single drive long term?

I have done some research on triple boot systems, and it appears that a third OS must be run virtually, but all the information I came across was a few years old. Microsoft is running a deal right now on Windows 7 for students so I would like to pick up a copy and try it out.
Is it possible to run 3 operating systems through Boot Camp 3.0? I am not interested in running a virtual OS.
Current Setup:
13" macbook pro
Snow Leopard and Windows XP through Boot Camp

Just an FYI. Tech Support at Allsoft states The Disk Warrior 4.2 Boot DVD will not Boot the new 2010 MBP's. They are waiting for information (software) from Apple.
Will need to use Target Mode or another Mac connected with Firewire till then. Boot from that then run DW from your MBP.

I have successfully striped two SSDs in Vista Business-64 on my MacPro1,1. I have used Vista's data carrier administration program for this. As expected the array isn't recognized in OS X. So I cannot just dump a Winclone image on the array. That would have been much to nice!
My next strategy was a total backup with Vista's own backup program on another HDD. That went without a hitch. I then hoped that booting the Vista install DVD with the backup drive present and the RAID0 array would allow me to restore the backup on the RAID array. Unfortunately Vista will not recognize the array running of the install DVD. Loading AHCI or IMSM drivers will not change this situation.
It appears that you have to make the dynamic data carrier active if you want to install Vista on it. Unfortunately the data carrier admin program will not let me do this. I would do it in DISKPART if I knew it was possible and how to do it.
So the question is does anybody know how to install Vista Business to a dynamic data carrier? If I cannot figure out this soft RAID0 I will ave to buy a RAID controller which I thought I might avoid at this point.

I'm a graphics professional taking the plunge into a Mac Pro. After some research, this is my notional drive setup:??GB SSD Boot Drive in the optical bay2 x 1TB 7200rpm SATA in RAID0, partitioned for 1.Data and 2.Scratch (therefore <2TB data)I obviously need to make sure that RAID0 is safely backed up. I've got an online backup service in case my house burns down and I'll be backing up individual projects onto optical media, but I will of course want to Time Machine the Data partition of the RAID.Now, for that Time machine drive I can either create another RAID0 from the same kind of drives (with the risk that entails), or for about the same money get a 2TB 5400rpm (leaving a drive bay free for future use, possibly another backup).

I'm basically after some suggestions or advice. There are two of us in this house both with two macs each and so all our machines are running OS X. I have downstairs my parents old desktop machine (Core2 Duo) running XP blah blah blah. But they have laptops now and aren't in the country atm. I want to put a new hard drive into this machine and create a server.
Our needs are fairly basic. This server needs to be a file server (for ~ 2TB HDD space), a print server but also a MySQL and PHP server. So far I've fired up iATKOS 10.5.5 onto the machine but I'm trying to keep this operation as legal as possible.My question is really about a linux server. A linux server is able to host a bunch of HFS+ partitions because I've tested that out before but I'm not sure it would work as a print server. How compatible would OS X be with a server (as described) running something like ubuntu or ubuntu server edition?

Is it technically possible for Snow Leopard to build into OS X the WINE project, and have seamless ability to install and use Windows applications on OS X (without X11 cluttering it up - and with the realization it wouldn't be 100% compatible?) Is that even possible? Would the WINE license prohibit it?

I would like to be able to build and maintain a website for my financially strapped public library as a service to them and then build a site for my genealogy. When I taught I developed our school's first website using Adobe PageMill about 12 years ago. I have forgotten most everything I knew.
I recently updated my Mac OSX version to 10.4.11. The rest of my profile is the same as shown.
I have been looking into the Adobe Dreamweaver CS3 and I have several questions. First, is this a good choice? Should I also purchase Fireworks CS3 and Contribute CS3 to make the job easier? (Or do I really need everything included in the Adobe CS3 Web Standard package?) Will my present computer system be able to handle this software? Do I need to upgrade my memory?
Also, should I consider downloading PageSpinner to work with in addition to Dreamweaver or will I be confusing myself more?
I have picked out some instruction books on developing websites and using Dreamweaver and I catch on to using software quickly, but I'm not sure about my hardware.

I have a G5, 1.8Ghz computer with OS 10.5.8 installed. Some problems developed and I tried to run Disk Warrior. The disk shows up on the desktop. but won't start when I select either the "C" key or use the option key. The same thing happens when I use an external drive that has the startup drive cloned several months ago. When I use the Option key only the original startup volume appears. When I use the "C" for Disk Warrior the the system folder appears and switches with a Question mark. Again when I try to boot from the OS 10.5 install disk, I have the flashing folder when I hold the "C" down. The same problem I had with Disk Warrior.
