How to stripe and mirror 4 drives on my Mac
I have a Mac Pro. 4 internal 2TB SATA drives. I've already striped two drives as one array. I then used Carbon Copy Cloner to clone my boot drive to the striped array. It boots up and works fine (with a BIG increase in disk speed). I've striped the other 2 drives as one array. Disk Utility doesn't seem to allow me to Mirror the first array to the second array (RAID 0 + 1).
Am I missing something here? Or do I need to buy a 3rd party app (like SoftRAID 4)?
thanks
Well this article http://support.apple.com/kb/TA24359 seems to explain how to us disk utility to make a raid that's a mirror set of two striped drive or stripe two sets of mirrored drives. I've always used raid utility to make my hardware raids.
While the article doesn't specify call out if creating a raid will destroy all data on your current raid; it seems implied; so I would suggest backing up the raid to an external drive before trying to create your 0 + 1 raid.
let me know how it turns out.

Unbreakable Linux on a Stripe and Mirror Raid
Hi all
I was wondering if there is any best practice with respect to the placement of the Linux OS executables on Raid storage.
We have a 12 x 500gb disk storage unit and intend to stripe and mirror everything giving a total of 3 terrbytes.
I was considering placing the Linux executables on the raid along with the DB files etc and would be keen to know if anyone would anticipate any problems with this configuration.
Thanks in advance.
Cheers

Thanks for your reply.
Under normal circumstances I would also put the Unix OS on local drives.
However, as we will be running a number of Virtual servers spread over a couple of physical servers under the control of Virtual Iron, the Unix OS has to sit on the SAN.
I was wondering if perfformance of the Unix and Oracle executables sitting on the Striped and Mirrored disks would be bad enough to dictate that I should dedicate 2 out of the 12 disks as a mirrored pair for the Unix and Oracle executables.
Thanks for any further input.

I have just installed Photoshop Elements for a MAC. MY photos were in iPhoto, I have 47,000 pictures and my drive on my Mac laptop is not large enough. I store my photos in iPhoto on an external drive. Can I store all my photos on an external drive when using Photoshop Elements? If so, in what format should they be stored in? I do I move them from iPhoto to the new storage location? How do I call them up in organizer? And how do I call them up to Edit? I do not want to store any pictures on my Apple Mac laptop. I want to store pictures on several external devices.
Yes you can store images on an external hard dive and have them referenced in Organizer. It’s best to export copies to separate folders/subfolders and that will ensure iPhoto does not get corrupted.
Alternatively you could continue to use iPhoto with the Elements Editor set up in the iPhoto prefs as your external editing app. Then there is no need to use Organizer and no need to duplicate your images.
You can then call up photos directly from iPhoto as normal with the additional option e.g.
Double-click on a thumbnail to edit in iPhoto editor.
Control (right) - click on a thumbnail to edit in the elements app.

How to reinstall a hard drive on a mac pro that was accidentally dragged out of Finder
How to reinstall a hard drive on a mac pro that was accidentally dragged out of Finder? I have files on this drive that I don't want to loose or corrupt.
If you mean you dragged the hard drive shortcut out of the sidebar of a Finder window, you're quite all right - that's just a shortcut and you haven't lost any files. You can get it back by going to Finder preferences (the Finder menu, then Preferences), click Sidebar, and tick the "hard drives" box fully to show all hard drives.
Post back if you did something different though.

How to erase and install new version os Mac Os X?
Can someone tell me how to erase and install new copy of Mac OS X 10.5.8 ?? IS there a way to do this without CD?? I no longer have the disks and I cant find a way to get this done.. The reason I want to do this is because a 12 year old was using this computer for a long time and there is a lot of junk stuff on the disk, so I want to start from fresh.
Thank you in advance.
Yani.Hi Yani,
Your out of luck without an Install Disc, & on dangerous ground also.
2 ways to go...
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the Erase tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Highlight the drive, select Partition Tab, then Format type... MacOS Extended Journalled, select the Security Options button, choose Zero Out Data, Erase... after completion do a new install.
Or...
Open System Preferences>Accounts, unlock the lock, click on the little plus icon, make a new admin account, log out & into the new account.
In the same pref pane highlight your old account, click the little minus icon, then use Disk Utility to Secure Erase Free Space. -
How to know which mirrored drives after mirroring.
Hi All
Any one used Veritas NetBackup together with Xserve Raid? After i mirrored drives 1 and 2 and the other mirrored drives 3 and 4, i have a problem knowing which is drives 1,2 and 3,4 in Veritas NetBackup, because after trying out backup on 1 and 2 .. it works but not on 3 and 4.
Thanks if anyone has some pointers regarding this issue.
MattI don't know how Veritas references disks (whether it uses volume names like the Finder, or device IDs like /dev/disk0), so I can't answer your question directly, however, the command diskutil list will list all disks in your system, as well as any arrays, showing you the breakdown of which disks constitute which arrays/volumes.

Network Vaults and Mirrored Drives
I just updated my server with a mirrored (Raid 1) drive and I was looking forward to putting an Aperture vault on the drive. Of course Aperture doesn't support network drives for vaults (yes, yes, I should have checked first...)
anyone out there find an alternative workflow that works for them. I still like the idea (and redundant) network drives backing up my pictures.
thx!
Dual G5, 15" MacBook Pro Mac OS X (10.4.8)Hi (I also from Seattle),
I also have a mirrored network drive. At the time I put Aperture 1.0 on my Quad G5, I couldn't put the Library on the network account, nor a vault. Now, I think I can at least use referenced files on the network account...but I choose not to. I don't know if the managed library can reside on the network drive. I don't think it can.
Regardless, the Library on the RAID might be nice in case of drive failure, but for the vault, I wouldn't trust it. If the library is corrupted, or files get deleted, I instantly replicate the error to the mirrored drive. Same for the vaults.
So instead, I have a pair of backups (Vaults) that I rotate off-site. I intend on having a third. It's easy, and fast. I don't keep the vaults connected all the time--I've had bad luck with drive failure in the past, so I take them online only for the task. Like I said, it's quick and easy. I have a 140 GB Library. The vault updates take a few minutes each time. I vault the library every time I add new images or make substantial changes.
Having tried a variety of ways of backing up, I'm really pleased with what Apple's come up with so far. Of course for those who need a network workflow, there's much to be desired...
BTW, I run my laptop with a Portable Home Directory. Of course, it can't run Aperture. If it did, I'd be exporting the projects I needed to work on to my home directory, and then it would be synched to the Laptop and back. -
Video Format Total Solution: How to Convert and Edit Video on Windows/Mac
More and More video formats are coming out with different video encoders and it makes our spare time more and more colorful. However, it is not to say that there is no problems. Actually, different video formats make it difficult to share video with others, even your own camcorder and iPod. Is there an easy way to convert videos effectively. Yes, there is.
In this article, I will show you guys how to convert videos on windows and mac.
Part 1. How to Convert and Edit Videos on Windows
For Windows users, you need a Video Converter(http://www.aiseesoft.com/total-video-converter.html) to do that for you.
Here I use Aiseesoft Total Video Converter(http://www.aiseesoft.com/total-video-converter.html)
Step 1: Download and install Aiseesoft Total Video Converter
After you download it to your computer, double click it and it is really easy to install.
You just need to click “next” and it will complete it in seconds. It will automatically run after installation.
http://www.aiseesoft.com/images/guide/total-video-converter/screen.jpg
Step 2: Load Video
Click “Add File” to find the video that you want to convert and click “open”. It will be loaded automatically.
Step 3: Select the target to decode
In the “Profile” drop download list you can find your target according the usage of your output video, such as if you want to put the video on your iPod touch, you can select the “iPod” in the first list and “iPod touch 2 MPEG-4 640*480(*.mp4)” in the second list.
Step 4: Set Advanced Parameters
After you select the right output profile, you can click “setting” button to set your advanced parameters. You can adjust video and audio settings separately. In video section, you can change “video encoder”, “resolution”, “frame rate”, “video bitrate”In audio section, you can change “audio encoder”, “sample rate”, “channel”, “audio bitrate”If you want to save this profile and settings and use it next time you can click “save as” button to give a name to it. And the next time you want to use it you can find it in the profile list named “user defined”.
Step 5: Choose a Destination
To browse and find a output folder for your output files or just the default one.
Finally, Click “Convert” button to begin your conversion, here in the converting
interface you can choose “shut down the computer when conversion complete” or “open output folder when conversion complete” or you just do not choose neither one.
Tips: How to Edit the Output Video
This video converter is also a video editor, you can use it to edit your output video as follows:
http://www.aiseesoft.com/images/guide/total-video-converter/effect.jpg
1. Effect:
You are allowed to adjust the “Brightness”, “Contrast”, “Saturation” and you can choose the “deinterlacing” to make the video more enjoyable.
2. Trim:
In “Trim” section you can pick up any part of the video to convert.
There are two ways to select the part of the video you want. One is set the start and end time in the box. The other one is to drag the start and end button in the processing bar.
3. Crop:
This function allows you to choose a certain play area to convert. That means you can choose a part of the screen you like to convert. For example, you just like the tv in the middle of the screen, then you can drag the frame around the preview window to select the tv and the output preview will show you the output video.In this section you can also choose the “zoom mode”, such as “keep original”, “full screen”, “16:9”, “4:3”.
4. Watermark
In the section, you can add a watermark on the output video to show people something, such as your name, website, studio name or other things. The watermark could be words and picture. You can adjust the transparent of the watermark easily to make it more beautiful.
Part 2. How to Convert Video on Mac
This time you need a Video Converter for Mac(http://www.aiseesoft.com/video-converter-for-mac.html)
Step 1: Add File
Click “Add File” button to load the video you want to converter
http://www.aiseesoft.com/images/guide/mac-video-converter/steps.jpg
Step 2: Choose profile and adjust settings
You can find your output video format from a drop-list called “Profile”You can also adjust the specific settings of the output video, such as “Resolution”, “Bitrate”, “Encoder” and so on.@ Tamwini
Your only goal is to sell software.

How to share external hard drive connected to mac with pc
I have and external hard drive connected to my mac-mini OSX 10.4.11
My iTunes music folder is in it. I want to share my music with my kids in my house so they can hear it in their windows xp computer with windows media player 11
I have the computers connected to a router and I can see the mac files from the pc but I cannot see the external hard drive that is mounted on the desktop of the mac.
The external drive is formatted as "Mac OS Extended (journaled)
Or.... If there is a way that I can duplicate my 80 gigs of music onto the pc that would be great.
I also tried to see the pc from the mac so that I can drag and drop some songs from the iTunes music folder right into the desktop of the pc and I can't get to the pc from the mac. I get an error that says the Alias is incorrect and the PC cannot be accessed.
Please Help my kids are driving me crazy for some music on their computer!
thanks in advance.Apple has a 'bunch' of articles on sharing iTunes.
Or look at the networking. And then whether you want to put MacDrive on the PC, or use NTFS format and NTFS driver (commercial or free MacFUSE).
And probably want to ask or look in iTunes for Mac and Windows discussions, too.
Most of the things I have (bookmarked) deal with Leopard, not Tiger, so not sure but pretty sure networking is now slightly different.

How to download and keep multiple maps using Mac/E...
I use my mac and this site
http://nokiamaps.site666.info/
to download maps via my mac to my E71. It works fine. I can install any map, however, only one map at a time.
I would be happy if anyone knows and could tell me how to download and keep several maps active using my mac and E71. For example, I would like to have US, Japan and some countries in Europe loaded to my E71.
I can of course keep several maps on my mac but I want to have them loaded to the E71.
Can I have several maps loaded in the E7? Where to put the maps (which directory)?I do not know if anyone is interested but I have figured out one way to do it. Not the nicest perhaps but it works.
On my mac I create a directory named MyMaps and then I download the maps I want and put them into directories (one directory per map). I copy using the -r flag, which merges/adds on files.
For example if MyMaps is empty and I use:
cp -r Sweden/* MyMaps/
I will get the Swedish map in MyMaps.
To add the map of Netherlands I simply do:
cp -r Netherlands* MyMaps/
I have now merged the map of Netherlands with the map of Sweden and all maps are in MyMaps. And I can add more maps by running cp -r again. And when I am done, I transfer the directory structure in MyMaps to my E71.
I had some troubles with the diskcache structure. It worked fine for me to remove everything (all files) in the diskcache. They will be created when I move MyMaps. -

Can't decide on how much RAM and flash drive..
Hi, I've just started my university course in Graphic Design, so I'll be needing to use programs such as photoshop.. indesgin.. illustrator. I want to buy a macbook pro 15, but I'm not sure if I should conisder upgrading to\or purchasing one with the highest amount RAM or Flash storage, or both! The 16gb Macbook is quite a bit more exspensive... so I was thinking to purchase the 8gb one for £1,563.60 and then upgrade it to 16gbRAM, do you think that's the best solution? or should I also be getting the higher amount of flash drive? (the 512GB instead of the 256GB)
Thank youThe RAM is integral to the logic board. There is no upgrading. Hardrive is not user changable.
A drawback of the rMBP.
At time of purchase only.

How do I and should I upgrade from Mac OSx 10.5 to 10.6?
I currently have OSX 10.5 on a 2008 macbook pro. Does it make sense for me to upgrade to OSX 10.6 and do I have to first upgrade to SnowLeopard to do that?

Yes, I agree 10.6 Snow Leopard would be excellent choice for your 2008 MBP, what it does is strips out the PPC code your not using in 10.5 Leopard and offer faster video drivers and some nice bells and whistles.
10.6 is faster than 10.5 (video driver improvements) and 10.6 is slightly faster than 10.7.1 (tested on the same hardware)
It might be that 10.7.3+ is possibly a hair bit faster than 10.6, I haven't seen any recent speed comparisons lately.
A advantage with 10.6 is you get to keep running most of your present 10.5 software, some will require a update to work in 10.6 under Rosetta which is a compatability layer.
Most all software and hardware drivers for older third party devices work for 10.6, so your good to go.
Do backup your files off the computer to a storage drive (not TimeMachine) and disconnect before making any major changes.
You can buy the $29 10.6.3 Snow Leopard upgrade/install disk from Apple online.
http://store.apple.com/us/product/MC573Z/A
Now about 10.7, it's a new OS that came out in July, it's all 64bit and thus it doesn't run Rosetta (of 10.6) and thus your 10.5 software will not work with it.
Some third party software is not ready for 10.7 yet, and a lot of hardware drivers for printers and scanners may not function for it. You will have to do your homework check this table.
http://roaringapps.com/apps:table
10.7 Lion represents a rather drastic change to OS X in some aspects that need getting used to, no boot disks, internet recovery and the MacAppStore etc.
10.8 is going to be released THIS SUMMER and nearly no software is ready for it obviously and won't run on older hardware (to be determined)
I think 10.7 should run fine on your machine, you may have to upgrade the RAM to 4GB to get better performance.
So you have to make a decision, if it's wise for you to have to buy all new versions of software for your older Mac and run 10.7 or stay with 10.6.8 and run the software you have (minor updates) until perhaps a year from now when 10.8 is out on brand new hardware and the bugs are worked out of it, buy all new software then.
IMO option #2 with 10.6.8 now, 10.8 later is a better choice than option #1 going with 10.7 and paying more money for software, or going without as some isn't ready yet for 10.7.
I don't know what or how much investment in software you have; if little, then 10.7 is nothing, if a lot then you perhaps may want to hold off 10.7 for now.
If you do decide to go to 10.7, I advise buying the $69 Lion USB thumb drive and option key booting from that, erasing the entire drive and installing 10.7 directly. Skipping right over 10.6.
With the Lion USB you can install 10.7 anytime you want, no internet connection required, however if you upgrade 10.5 to 10.6 ($29) then to 10.7 ($29), then you have to use Internet Recovery from your boot drive, I don't know how reliable your Internet is, but a $69 USB is certainly more reliable for only a few dollars more.
Good luck. -
How to use an external drive with 2 Macs?
Using an external drive for LR 5.4 files and can download and view without any issues on my MacBook. However, when the same drive is attached to my iMac I cannot download or view any files on the external drive that were added after March of this year. Any ideas on how to go about resolving this issue?
The following screenshot might be helpful. It shows where in Lr preferences you can configure which catalog Lr uses as the default. If you need to direct it to an external drive then use the 'Other' option to point to this drive then next time Lr launches set it back 'Load most recent catalog'
