Mac Pro can't find hard drive with Snow Leopard installed on

Hello there,
I have a three harddrive setup.
Harddrive 1 is in bay 1 and has two partitions.
1: For system and apps
2: For Documents and stuff
Hard drive 2+3 are in Bay 2+3 and are combined to a RAID 0 drive.
Some time ago I installed Leopard and the brand new an formatted hard drive.
It happened that it always took 2 start ups to run Leopard because always on the first time it didn t find the system on hard drive one. Pushing the 'D' button often helped.
Of course that was nothing to work with, although I at least could get some work done, once I loaded Leopard successfully.
So I tried Disk Utility, fsck without success.
I also tried the way of using fdisk to mark the partion as active, which only resulted in now not being able to boot at all.
Booting from DVD I also tried choosing my Leopard install on my hard drive as boot device (it has always shown up here) but still without success.
I am afraid things are quite messed up, since there were a few things happening at one time, which I am not overly happy about now. (Installing new RAM, installing SNOW LEOPARD on the new harddrive 1 in bay one, having still the RAID with LEOPARD on in bays 2+3).
I am already certain to do a fresh and complete reinstall of the system, I have my backup, but still there is some iTunes music and a few documents I haven't backed up yet, which I'd rather would not like to lose...
Put it short:
What could I do to get my system running at least once?
Thanks a lot,
max.

After some research I found out about the nice TargetDiskMode which I used to save all my important data with my MacBook.

Ready to perform a complete and fresh install now!

Can I boot an internal hard drive with snow leopard?

Hi, I Have an Mid 07 macbook which i'm in the process of upgrading. I have a hard drive that i am up grading from 160gb to 500gb. my problem is i dont have a boot disc, because it's ethier been lost or didn't come with one. my question is can i just format the new hard drive with a copy of snow leopard?

Clean Install of Snow Leopard
     1. Boot the computer using the Snow Leopard Installer Disc. Insert the disc into the
         optical drive and restart the computer. After the chime press and hold down the
         "C" key. Release the key when you see a small spinning gear appear below the
         dark gray Apple logo.
     2. After the installer loads select your language and click on the Continue
         button. When the menu bar appears select Disk Utility from the Utilities menu.
         After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
         size.) Click on the Partition tab in the DU main window. Set the number of
         partitions to one (1) from the Partitions drop down menu, set the format type to Mac
         OS Extended (Journaled, if supported), then click on the Partition button.
     3. When the formatting has completed quit DU and return to the installer. Proceed
         with the OS X installation and follow the directions included with the installer.
     4. When the installation has completed your computer will Restart into the Setup
         Assistant. Be sure you configure your initial admin account with the exact same
         username and password that you used on your old drive. After you finish Setup
         Assistant will complete the installation after which you will be running a fresh
         install of OS X. You can now begin the update process by opening Software
         Update and installing all recommended updates to bring your installation current.

External Hard Drive with Snow Leopard/Windows 7

I just bought a 500GB external HD that I would like to be able to use with Snow Leopard AND Win 7. I won't be using it for any Time Machine backups. I just want to be able to read/write files on it with both Leopard and Win 7.
Is there any recommended format procedures in order to be able to do this. I may be wrong, but I don't think I can read/write to my external Time Machine external hard drive with my Windows lap top running Win 7.

a TM drive must be formatted mac os extended and windows can't even read that without extra software like Mac Drive. It also requires that the partition scheme be GUID which it's most likely not at the moment so repartition the drive with correct partition scheme now if you do decide to use it for TM in the future. also, snow bootcamp drivers once you install them in windows will let you red (but not write) to mac os extended formatted drives.
the only FS which is natively read+write from both OS X and windows is FAT. but it's very old and has many deficiencies especially on the OS X side.
but it's good for interoperability.
or you can format the drive NTFS and use some software like NTFS-3g or NTFS for mac by paragon to make it writable from OS X.
you may also wish to split the drive in two partitions and format them differently.

Macbook pro can't find hard drive!

I'm using a 13" Macbook Pro on Lion OS and yesterday I was working on my thesis and I opened up Pinterest for what must have been thirty seconds before I was met with the pinwheel of death. I waited five minutes, and then I decided todo a manual shutdown. and then when I started it up again all I could see was a flashing folder with a question mark on it.
So i restarted it holding the option key, and my only option is the internet recovery. So I went there, and when I attempted to reinstall the Mac OS, I realized that it couldn't find my hard drive as a destination to download it. So I went to my local apple reseller store here in Norway and ofcourse they had no idea what to do withnit because they've never seen the problem before - they offered to help, but They would need to take it in for 2-4 weeks! and I don't think my exam period can handle that.
So i left it alone for a night. In the morning I tried to restart it, but the same thing Happened. what should I do? Is my poor hard drive dead?

It could be that your hard drive IS dead or it could be something as simple as a faulty SATA cable - hard to diagnose from a distance (and I'm quite surprised that an AASP would be baffled by something that MAY be something simple).
Since you didn't find the Lion Recovery partition when you booted up whilst holding the option key, I'm assuming that the drive is dead or that the SATA cable is bad.
Assume the drive is dead - the best thing that you can do is get a replacement hard drive, an external enclosure for your 'dead' drive and then use something like DiskWarrior to try to recover your most important data (which would be your thesis - and I'm assuming that you don't have a backup scheme in place?).
I'm not sure that you should take your machine back to the same reseller - are they an Apple Authorized Service Provider? Go here -> https://locate.apple.com/no/no/ - and see if there's an AASP near you. They should be able to actually diagnose the real problem, before you go through the agony of replacing your hard drive.
Good luck,
Clinton

Can't boot from external hard drive with Snow Leopard

I bought a new Macbook Air with Lion. I have my old Snow Leopard installation cloned onto an external hard drive, and I want to boot from it. I can choose my external hard drive during boot, it shows the Apple logo, but after that the screen goes black and nothing happens. Is there a way to fix this?

Can't be done. Snow Leopard does not contain necessary drivers and perhaps other items required for OS X on the 2011 MBA. In fact, the version of Lion on the App store won't install on the 2011 MBA.
This is totally normal in Apple's world. A new version of MAC hardware that comes with a new version of OS X installed usually will not operate correctly with previous versions of OS X.

I'm trying to boot my new iMac running Mavericks from an external hard drive with Snow leopard but it fails with a window telling me to power down manually. It works with my old iMac.

I have made a bootable copy of OS 10.6.8 onto an external G-drive from my 2007 24" iMac with success. I can't boot up my my new 2013 imac that has Mavericks installed. Any suggestions?

Any ideas what do i have to do?

Well, let's hope that nothing was jiggled out of place when you were installing the new hard drive. Your optical drive may just be out of alignment or the disc you have is "dirty." Get a lint-free cloth and some rubbing alcohol, then clean the disc as thoroughly as you can starting from the center and working outward in a concentric circlular motion. See if that helps. In particular clean the inner portion well.
If this does not help, then you have a problem. You have opened the computer yourself. That action voids all support from Apple. If you take the computer in for service the store may refuse to service the computer. This is not related to your now expired warranty.

U410 ultrabook: Can I defrag hard drive with SSD cache?

Hi,
I would like to know if I can defrag my hard drive with 24G SSD cache. I heard that it would be bad to defrag the SSD part so I would like to defrag the regular hard drive portion only (1TB). I right clicked the drive but I see four drives and can't tell which one I should defrag. It looks like the first c drive is the one, but I am not sure. Any comments would be helpful. Thanks.

You are right that by default, drives are set to be defragged automatically. But you can also do it manually and when the date of the task is not yet due.
Re ssd, are there permanent files in that drive? By permanent, I mean data, programs, etc.. Not the temporary files used by runned programs and the system using the caching process.

I tried to install a new hard drive using Snow Leopard to back up with Time Machine. When I installed the new HD I installed Leopard (10.5) on it and tried to use time machine to restore the backup I had made using 10.6. Kernel panic screen occurred.

I backed up my system using 10.6 Snow Leopard's Time Machine to an external hard drive. I did this because I purchased a new internal hard drive to upgrade my 2007 White Macbook from 80GB to 320GB. When I installed the new hard drive, I installed 10.4 (Tiger) and then 10.5 (Leopard) and once Leopard was in I tried to use Time Machine to restore my backup from 10.6 (Snow Leopard) and received a kernal panic screen directly after the bootup.
The screen had code asking for 10.6, so does this mean that the computer is searching for Snow Leopard? If so, how can I do this? Will a bootable drive with Snow Leopard on it be able to solve the issue or will I somehow need to find a way to wipe out this new hard drive?

Booting From Snow Leopard Installer Disc
1. Insert Snow Leopard Installer Disc into the optical drive.
2. Restart the computer.
3. Immediately after the chime press and hold down the "C" key.
4. Release the key when the spinning gear below the dark gray Apple logo appears.
5. Wait for installer to finish loading.
Drive Preparation and Installation
1. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
7. After formatting is complete quit DU and return to the installer. Install Snow Leopard.

Can I have mavericks time machine on one partition of a WD external hard drive and snow leopard data on another

can I have mavericks time machine on one partition of a WD external hard drive and snow leopard data on another

If you want to and it is so large that it has room (350% is a good estimate for TimeMachine), then use a partition(s) to hold system restore images or bootable clones. Or VM images.
Using SSDs most Mac Pro models can easily hold 6 or more storage devices inside, except the nMP cylinder 6,1's; which do need external Thunderbolt and USB3.
System drive / data / scratch / backup data / backups of system / ....
I recommend a couple system backups, especially when faced with dual boot situations as well as an OS that is still undergoing updates and changes.

Will Time Machine with Leopard Sync With New Hard Drive and Snow Leopard?

My computer is a 20" iMac that I bought in late 2008. The hard drive had trouble so Apple repaired with disk utility. Week later, more trouble so they did full hard drive erase. Data was backed up on Time Machine, 500GB also bought in 2008. After full hard drive erase, and reinstall of basic software, upon reboot, computer would power on then immediately off. It doesn't get past white screen. They advised a new hard drive install is needed.
A computer friend can install a hard drive just fine for me. However, I do not have the Leopard install disc. He could do it with Snow Leopard but I am scared. I'm afraid because my Time Machine last backup was with Leopard, not snow Leopard. I do not have my application discs with me, they are in storage in another state. Thus, if upon adding replacing hard drive and installing Snow Leopard my computer won't be able to sync FILES and APPLICATIONS from Time Machine because its on Leopard I will have a problem.
How can I either 1)Get a Leopard install disc and do that with the new hard drive install OR 2)make sure that a Snow Leopard install with new hard drive won't prevent my Time Machine from being able to install the saved FILES and APPLICATIONS if I don't have original APPLICATION (ie Aperture, Photoshop) with me? Thanks for any help you can provide.

Hi, and welcome to the forums.
That Mac should have come with Leopard. If so, call AppleCare. They'll send you replacement discs for a nominal fee.
Once this is sorted out, make a 8-10 GB partition on an external HD or your internal HD, and use the Restore tab of Disk Utility to copy the Install disc to that partition. Then you can boot and run from it instead of the physical disc. It will boot and run much faster, too.
He could do it with Snow Leopard but I am scared.
If he does, and doesn't provide a retail Snow Leopard disc, you must buy one ($29). It's a violation of the license to share software, and you'll need a SL disc to do things like restore a Snow Leopard backup, or the Snow Leopard Apple apps, or repair the internal HD.
Your best bet is to stay with Leopard, at least until you have access to your 3rd-party software discs.
What you can do, however, is borrow his Snow Leopard Install disc (assuming it's a white Retail disc, not a gray one that came with his Mac), and use it to do a full system restore from your backups. That's not a violation of the license, since you don't install or use OSX from that disc; you just use the Installer utility on it to restore the Leopard OSX and all your data from your backups.

Welcome to Apple Support Communities. We're users here and do not speak for "Apple Inc."
Power on the computer and insert the DVD immediately.
Hold down the 'C' key to boot from the Snow Leopard DVD.
http://support.apple.com/kb/ht1533
After selecting the appropriate language, if necessary, select Utilities, and Disk Utility.
You'll likely need to partition and format the new drive before it's recognized.

I have Lion as my current and main OS. Is it possible to partition part of my hard drive for Snow Leopard?

I have Lion as my current and main OS. Is it possible to partition part of my hard drive for Snow Leopard? I'm good on partitioning but when I insert the Snow Leopard install disk a message tells me I can't run the install program because I currently have Lion installed... obviously. Have I gone about this the wrong way? Do I need to boot the computer using the Snow Leopard install disk instead of my main HD?

Apple will never update that as for the most part it is true, and the fact that they really don't want you to run older OS X versions (for whatever reason).
Now this probably won't work with the next line of MBPs and MBAs that come out. But it is for the current builds.
But as I stated you need one of the lastest builds of SL for it to even boot the system.
It won't work with the retail 10.6.3 DVD disc. That version does not have the correct drivers for the newest Mac's.

Encore CS4 can't create a project with Snow Leopard

After many crashes on a Windows XP 64Bit Dell workstation trying to render a project, I thought I would create the project from scratch on my MacBook Pro 17" with Snow Leopard installed. I get a strange string error message trying to create a new project. It goes back to the welcome screen and I try to open the project it just created. I get a second error message that the project was created with Windows and can't be opened with a Mac. Strange. Then I get a third message saying an input contract violation has occurred. I guess I'm in trouble somehow for this . I think I was successful at creating a service issue with this, but I only grabbed the first error message at that time.
I'll attach the messages here....
Rick

Sorry to say, no I have not. I was able to complete the work on my Windows XP 64Bit system.
The MacBook is my personal laptop, but I use it as backup to what I am doing on the workstation.
I was sent some info on permissions and maybe starting in safe mode. I don't know that "safe mode" exists on a Mac, and I am the only owner/user on it. Permissions should not be an issue. No time right now to do an uninstall/reinstall, but that's what I was thinking of doing.
It tells me I can't create the file, yet it appears in the folder. Then I try to open it and it says it was created with a Windows machine. Neat trick.
I just tried again, no luck.

Bought you Mac Mini from Amazon? Did it come with Snow Leopard installed?

I want to buy a Mac Mini from Amazon simply because it's cheaper and there's no tax, the question is, does it come with Snow Leopard like the one from Apple does?
I am not being a cheap @ss here, i lost my job and trying to save every penny i can.
Totals:
Amazon: $577.95
Apple w/student discount: $599.78
The 9.75% tax is killing us here in CA

Even if it does not come with Snow Leopard installed, or the upgrade drop in disk, you should still be able to get it for S&H from Apple thru the Up-to-Date program.
... If you’ve purchased a qualifying computer or Xserve on or after June 8, 2009 that does not include Mac OS X Snow Leopard, you can upgrade to Mac OS X Snow Leopard for $9.95.*
This program ends December 26, 2009. Your completed order form must be postmarked or faxed within 90 days of the date of your purchase of a qualifying computer or Xserve (described in this offer) or by December 26, 2009, whichever is earlier.
Also, you may want to look into Apple's refurbished Mac minis. They are usually a Mac that was DOA when shipped to a customer new and has been repaired by Apple. They are technically brand new and carry the same warranty. Occasionally they have surprises, like upgraded RAM.
