Restoring Snow Leopard DVD in Disk Utility cannot scan for restore?

Is anybody able to scan the .cdr file so that it can restored to other media say flash drive etc?
Whenever I try to do the scan for restore it says prompts me to authenticate and then tells me
Unable to scan Mac OS X Install DVD (invalid argument)

I have exactly the same problem.

The Tale of the Beeping Macbook - AKA- My Macbook Pro keeps beeping when trying to boot into Snow Leopard Disc's disk utility

Quick back story: about a month ago my macbook was falling and I caught it quickly, I had a game controller in my hand and it lightly hit it whilst I was catching it; the laptop made no contact with the floor, couch etc. Upon reveling in my epic matrix esque catch I noticed it was beeping and the screen was completely black - Horrified I held down the power button for a forced power down and then turned it back on to see that it was fine, along with no visible scars, dents etc to the chassis. Now flash forward to present day, and the macbook pro is only two months old (bought may 4th 2011) and I notice it's got some slightly irregular slow loading points when loading a browser, photoshop, etc. I do the standard disk utility to verify the disc and it says
"Checking volume bitmap.
Checking volume information.
Invalid volume file count
(It should be 537095 instead of 537096)
Invalid volume directory count
(It should be 161641 instead of 161640)
The volume Macintosh HD was found corrupt and needs to be repaired.
Error: This disk needs to be repaired. Start up your computer with another disk (such as your Mac OS X installation disc), and then use Disk Utility to repair this disk."
So I put in the snow leopard disc to go to the disk utility within, reboot the laptop, and it goes to the gray boot screen with the dark gray apple logo and stays there whilst doing the aforementioned beep from my spider-sense catch. Does anyone happen to know what is wrong? Would that tiny tap from my controller when catching it have caused this problem I have now? Is there anything I can do at home to fix this since I can't get to the disk utility on the snow leopard disk? Will Batman ever get out of the Joker's trap? Or am I better off just making a genius bar appointment? Thanks in advance.

Are you using the Snow Leopard disc that came with that Mac? A gray disc that came with a different Mac won't boot yours, and a Retail (white) disc with a version of OSX earlier than the one your Mac came with won't boot it, either.
If you don't have the right disc, do you have an external HD, or can you borrow one?
(By the way, your post shows you're running Tiger; you might want to update that.)

Snow Leopard Latest Version - Disk Utility TAKES FOREVER to Backup Disk

Hi,
it is pretty much as the header describes.
I have chosen, New Image from Folder... in DU.
Then I select my boot drive which I want to Backup.
It has been 45 minutes and DU has copied 13 GB increasingly. And is still going at it.
I have 500GB on that drive and this way it would take forever.
Now, if I enter the terminal and do a ditto it will copy about 10GB per minute.
Any ideas why DU is soooooooo SLOW.

DU isn't slow, however, you are trying to backup into a disk image which is slow. If you simply use the Restore option of DU to backup, then it will go faster. You should not do a backup into a disk image. It's unnecessarily slow especially if you opted to encrypt the image. DU's Restore option will put a bootable clone onto the backup drive.
Clone using Restore Option of Disk Utility
1. Open Disk Utility from the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4.Check the box labeled Erase destination.
5. Select the destination volume from the left side list and drag it to the Destination entry field.
6. Select the source volume from the left side list and drag it to the Source entry field.
7. Double-check you got it right, then click on the Restore button.
Destination means the backup drive.
Source means the internal startup drive.

I am in the process of updating the os of my macbook pro and have installed from the snow leopard dvd and did the 10.6.8 combo v1.1 as well and wis to update further but i now cannot get preview so i am concerned about going forward. how to get prev

I am updating the OS on my MacBook Pro from 10.5.8. I have installed 10.6.8 and the 10.6.8 combo v1.1. I cannot open my older version of Preview and do not appear to have a newer version which i thought would be on the Snow Leopard dvd. How can I get the correct version of Preview and is it advisable to upgrade to OS7 andOS8?

It is always installed with whatever new version of OS X is installed or appropriate updates. Since you plan to go forward your choice depends on your model. I would urge you to perform a clean install instead of continuing the upgrade path which may interject incompatibilities.
Upgrading to Yosemite
You can upgrade to Yosemite from Lion or directly from Snow Leopard. Yosemite can be downloaded from the Mac App Store for FREE.
Upgrading to Yosemite
To upgrade to Yosemite you must have Snow Leopard 10.6.8 or Lion installed. Download Yosemite from the App Store. Sign in using your Apple ID. Yosemite is free. The file is quite large, over 5 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
    OS X Mavericks/Yosemite - System Requirements
    Macs that can be upgraded to OS X Yosemite
         1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) - Model Identifier 5,1 or later
         3. MacBook Pro (Mid/Late 2007 or newer) - Model Identifier 3,1 or later
         4. MacBook Air (Late 2008 or newer) - Model Identifier 2,1 or later
         5. Mac mini (Early 2009 or newer) - Model Identifier 3,1 or later
         6. Mac Pro (Early 2008 or newer) - Model Identifier 3,1 or later
         7. Xserve (Early 2009) - Model Identifier 3,1 or later
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
     Are my applications compatible?
         See App Compatibility Table - RoaringApps.
Upgrading to Lion
If your computer does not meet the requirements to install Yosemite, it may still meet the requirements to install Lion.
You can purchase Lion at the Online Apple Store. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.
Before attempting a clean install you want to first download the appropriate installer application from the App Store. It will download into your Applications folder. You need to make a copy of it in your Downloads folder so you can make a bootable USB flash drive:
Make Your Own Mavericks, Mountain/Lion Installer
After downloading the installer you must first save the Install Mac OS X application. After the installer downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.
   2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
Open Disk Utility in your Utilities folder.
After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the leftside list. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
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.
Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.
Use DiskMaker X to put your installer clone onto the USB flash drive.

You can also create a Yosemite flash drive installer via the Terminal. Yosemite has its own built-in installer maker you use via the Terminal:

Restoring my System with Time Machine to a new HD without the Snow Leopard DVD

Hi there,
I changed my HD in my MacBook Pro to a bigger one and then wanted to Restore the System via Time Machine onto that new HD. Sadly I dont have the Snow Leopard DVD that was coming with the MacBook. Though I have another Snow Leopard DVD, that I purchased earlier for my older Mac. Now the Problem:
When I try to Boot the Macbook Pro from the older Snow Leopard DVD it always freezes and says: "You have to restart your Macbook. Press the power button until it switches off and then press the button again". But iwill not boot from the DVD.
Is there another possibility to Restore my System from my Time Machine Backup to the new HD?
Kind Regards

You can't use a machine specific OS X install disk with another model of Mac.
It has to do with hardware drivers being on one disk and not applicable to another machine, why you get the kernel panic.
Is there another possibility to Restore my System from my Time Machine Backup to the new HD?
No. You need the OS X install disk.
Choices depending on what your machine is:
1: If your machine with the missing OS X install disk originally came with 10.6.3 or later, call Apple for machine specific replacement disks, there will be a fee of course. That's the only ones that will work.
2: If your machine originally came with 10.6.2 or earlier, you can choose to buy the 10.6.3 retail disk from Apple online, however it contains no free iLife. It comes faster.
3: If your machine originally came with 10.0 - 10.6.2, and you want the free iLife, then order the machine specific versions from Apple, however it might take longer.
4: If your machine originally came with 10.5, and your now on 10.6.x via the 10.6.3 retail disk, you can extract the free iLife from the 10.5 disks using Pacifist from CharlesSoft if you don't want to buy iLife.
You will need this disk regardless in case you need to #18 Reinstall Just OS X or #20 Erase and Install OS X or perform #4-#6 repair proceedures:
Step by Step to fix your Mac
Is there another possibility...
Yes, once you have gotten a new OS X install disk, consider making bootable clones.
It's software that can clone your entire OS X drive/partition (no Bootcamp or Filevaulted) to another external drive and you can easily hold the option key to boot from it.

If leopard won't boot from dvd, use disk utility mount to partition

wanted to share a way that i successfully installed os 9, tiger, and leopard on 1 hard drive. first of all, leopard was the only installation that i had difficulty with. it would not boot off the original dvd, no matter if i held down the 'c' key or the option key, so this is what i did after a lot of reading on the internet to try and troubleshoot this issue.
First thing i did was partition my internal hard drive in 3 partitions using disk utility. the 3rd partition was around 9gb. I installed os9 first on the 1st partition, i then installed tiger on that same partition. then i put in my leopard dvd, and opened up disk utility. and clicked on "restore", and dragged the dvd image as the "source", and chose the 9gb partition as the destination, and clicked on restore. then, i changed the "startup disk" to start from the 9gb where i just restored the image, and rebooted, and went through the leopard setup and chose the 2nd partition as the place to install. this should work with the dvd, or if you made an image from the dvd. I hope this helps someone else whose dvd won't boot, because it was very frustrating after you purchase a faster processor, and faster video card so that your system meets the requirements, and then the dvd won't boot.

Two ways. Use another computer to restore the install disc to one of those ext HD. Then, use it to boot the other machine. Get an ext CD/DVD reader and use it to read the install disc and boot the machine. However, if both the HD and optical reader are kaput, then a trip to an Apple repair station is in order.

How to restore snow leopard without disk.

Hi I have a macbook with snow leopard on it, and I recently tried to restore it with the disk until the superdrive litterally carved grooves into the disk. So I know I can purcahse replacement disks, but the disk drive doesn't work, so what do I do now? Is there any way I can do it without the disk, or will I have to drop 100 dollars into a disc drive and a new replacement disk? I would really prefer not to so any help is appreciated.

How to Use Pacifist to Replace Deleted or Missing OS X Components
Insert the OS X Installer DVD into the optical drive. Use a simple utility like TinkerTool to toggle invisibility so you can see invisible items. Alternatively, open the Terminal application in your Utilities folder and at the prompt enter the following:
defaults write com.apple.finder AppleShowAllFiles Yes
Press RETURN.
To turn off the display of invisible files repeat the above command substituting No for Yes.
The install packages are located in the /System/Installation/ folder on the DVD.
Download the shareware utility Pacifist from VersionTracker or MacUpdate. Use it to extract a fresh copy of the missing item(s) from the file archives on your OS X installation DVD. The file archives are in the /System/Installations/ folder (use Go to Folder option in the Go menu of the Finder.)
Here are Four Basic ways to use Pacifist (courtesy of George Orville.)
A. Drag a .pkg icon onto the Pacifist window .....proceed to step 7.
B. Click on “Open Package ....” and navigate to package desired and click “Open” in the open/save window.....proceed to step 7.
C. Insert Mac OS X installer CD and when it mounts, navigate to .... Menu->Go->Go to Folder.

/Volumes/disc name/System/Installation/Packages (where disc name is the name of the CD/DVD that you inserted.
• Click on the "Go" button .....
• Drag a .pkg to Pacifist..... proceed to step 7.
The package you'll need will have to be discovered by trial and error, but for most applications you should start with the Essentials.pkg and/or Additional Essentials.pkg.
D. Insert your Mac OS X install disk 1 .... and open Pacifist.
1. In Pacifist, select "Open Mac OS X Install Packages" ... dialog may appear asking for disk 2, then disk 3 and finally disk 1 again.... {if DVD is not used)...If “Stop Loading” is selected...the procedure will stop!!!
2a. When loading is complete, a new window appears, click the triangle to display contents of each package...Select item and proceed to step 7.
2b. or click the “Find” icon in the Pacifist window and type the name of the software you need.
3. In the list that comes back, click the top most entry for the item that you want. ..... that is the one for the English language.
4. On the top of the Pacifist window, click “verify” .... you will probably be prompted for your password.
5. Enter checks for.... “verify permissions” and “verify file contents.” and click “verify” ....enter password when prompted.... you will get back output which may look like this:
20 files were scanned.
20 of 20 files were present on the hard disk.
0 of 20 files had file permissions that did not match those specified in the package.
0 of 20 files had checksums that did not match those specified in the package.
6. Click “close”. Go to step 7.
Extract or Install........

• Pacifist may find that a file it is installing already exists on the hard disk. Pacifist will present you with an alert panel....
Stop
Leave original alone
Update ..... Default selection
Replace .... Replace option should only be used on full install packages

Mac Pro not recognizing bootable DVDs and Disk Utility giving odd results.

My issue is complex, but I'll try my best to explain it as I can.
One has been resolved it seems, but I am including it so that the whole issue can be seen in context.
Friday, May 16, 2014
Last night, after rebooting my Mac Pro from my Bootcamp partition (I'm using Windows 7 Professional if that information is helpful) I received a kernel panic upon Mac OS X booting (Mac OS X 10.6.8).
My first action was to launch Disk Utility to verify the Mac HD, verify was stopped by disk utility citing that I should insert my Mac OS X install DVD and repair the disk.
I tried booting from my Snow Leopard install DVD. After the grey Apple logo appeared with the gear spinning below it remained for roughly ten to fifteen seconds (a little long) — then the Apple logo changed to. A grey prohibitory sign (circle with a diagonal line through it, the spinning gear remained. — I tried booting from the Snow Leopard DVD a few time, same result.
Following this I tried booting using Disk Warrior, same result again.
I tried booting both the Snow Leopard and Disk Warrior DVDs in both my upper and lower optical drives, with no change.
I decided to leave the issue and call Apple Support in the morning
Saturday, May 17, 2014
This morning I woke my Mac Pro from sleep, opened Disk Utility and tried verifying the hard drive to see if it was temporary — same result, 'please insert the Mac OS X install DVD and repair the drive.' — I also tried booting the install DVD again with no result.
I then booted my Mac into Safe Mode to check my hardware.
Upon opening Disk Utility and verifying my Mac HD — the result "Macintosh HD appears to be OK", rand the test again to see if this was an anomaly, but disk returned another pass.
I performed a normal restart of my system, although Finder was a little slower to load than normal, the system booted correctly. — I then launched Disk Utility and verified the Mac HD, it returned another pass.
This confused me, after a call to Apple Support the tech explained that 'sometime a Safe Mode boot will fix problems because it disables all non-essential processes when booting. — That makes sense to me.
However.
The issue of my Mac not recognizing bootable DVDs remains — it reads disks correctly, it just will not boot them.
Other steps I have taken to try and resolve this remaining issue.
1. a PRAM reset. — No change.
2. an SMC reset. — No change.
3. Removal of newly installed RAM. — I have tried both running the old and new RAM separately, no change using either combination.
4. Running bootable DVDs in different optical bays. — No change from both bays.
a. My upper drive is an MCE Blu-Ray/DVD combo drive, but I have booted from this drive before. (Less than six months old.)
b. My lower drive is LG DVD-RAM combo drive, I have also booted from this drive before. (Over one year old, replacement for an Apple optical drive.)
None of the above steps have helped, I still cannot boot from my optical drives — I always receive a prohibitory sign shortly after the Apple logo.
Other system information:
Mac OS X 10.6.8
8GB of RAM (4 x 2GB)
500GB Western Digital Caviar Blue HDD (less than a year old, boot drive for Mac OS X 10.6.8)
1TB Samsung HDD (for data storage and also containing Bootcamp partition)
2TB HDD (cannot remember manufacturer, contains Time Machine backups, as well as data storage)
ATI Radeon HD 5770 with 1GB of VRAM
Sorry for the long post but I really need to be able to boot from my optical drives.

Update: found an old Mountain Lion installation USB flash drive I created a while back.
I am able to boot from the ML USB flash drive, but am still unable to boot from my either my Snow Leopard Install DVD or my Disk Warrior DVD. — I have verified both DVD and they pass verification tests.
This leads me to believe that the problem resides either in the Mac, or in BOTH the Snow Leopard and Disk Warrior DVDs.
Since I am able to boot from a USB drive, I will look into the possibility of creating a bootable Snow Leopard drive, and perhaps also a Disk Warrior drive — at least until I can resolve the 'not able to boot from DVD' issue.

Restore Snow Leopard From time Machine without an Optical drive

I have a couple of year old Macbook with a bad optical drive.
I want to pull the hard drive out of the Macbook and replace it with the original drive that came with the machine. The problem is that the original drive has OSX Leopard and I would like to get snow leopard on it. I have a good time machine backup that i could use, but i do not know how to restore the entire disk without using the OSX install DVD.
Is there anyway that i can do a time machine recovery without using the optical drive.
Thanks.

In order to restore Snow Leopard to that drive, it will need to be formatted using Disk Utility and I can't think of a way to do that without the optical drive unless you use a different Mac or an external optical drive.

Restore snow leopard without removing files/preferences

I installed Lion when it first came out but i want to go back to snow leopard to be able to use Pro tools 9 software. However, i dont want to lose some files and settings. How can i do this? i do have a time machine disk which was used atleast once with Snow leopard. Thanks

Backup first. Then,
Downgrade Lion to Snow Leopard
1. Boot from your Snow Leopard Installer Disc. 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. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.
If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions. If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion files.

Can your iMac even startup from a Snow Leopard disc? In order to install Snow Leopard on your MBP you need to boot the iMac from the Snow Leopard installer DVD. The MBP is then started in TDM. Then follow this:
     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.
         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, click on Options button
         and select GUID, click on OK, then set the format type to MacOS Extended
         (Journaled, if supported), then click on the Apply button.
     2. 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.
     3. When the installation has completed your computer will Restart into the Setup
         Assistant. 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.
When the installation is completed the MBP should restart into the Setup Assistant of Snow Leopard.
I should warn you that the above may not work because if your iMac came with Snow Leopard, then it came with a version that was exclusive to that model meaning it may not work on the MBP, and that may be why you couldn't boot it.
You can order replacement discs for the MBP from Apple:
Apple Store Customer Service at 1-800-676-2775 or visit online Help for more information.

IMac will not boot from Snow Leopard DVD or original Leopard disc!

Hey,
I am going mad! I am trying to update my iMac (with original Leopard installed) to Snow Leopard. Here is what I have tried:
Using the Snow Leopard DVD:
- A standard install: the disc ejects after about 15 minutes.
- Put another working DVD in and verified it in Disk Utility, all ok.
- Verified the internal hard drive in Disk Utility, all ok.
- Verfied the SL DVD, all ok.
- Decided to try a clean install, so backed up everything.
- Tried to boot from SL DVD by using the Utilities option, it ejects the disc at restart.
- Tried to force it to boot to the DVD by restarting and holding the C key, it ejects.
- Restart holding the Option key, it ejects.
- Restart holding the Ctrl, Alt and Option keys, ejects.
- Everytime it ejects and starts up normally.
- So I cleaned the disc, updated all the firmware, reset the NVRAM/PRAM via holding keys when restarting, and repaired disc permissions.
- Tried to force it to boot again, ejects.
- Tried to put the disc back in straight after it ejects with all the steps, still starts up normally.
- Changed the start up disc in System Preferences to the SL DVD, restart, it ejects.
By now I am readying the noose...
- Dug out the original Leopard installation CDs.
- Repeated all the forced boot restarts (C key, Option key, Ctrl, Alt, Option keys), same story.
- Repeated changing the start up disc in System Prefs, same story again.
- Call Apple Support, they told me to try everything I have tried and that the DVD drive is dodgy, well it works with everyhting else! Burning and reading! I really don't want to have to go to an Apple Store- it's miles away (a costly journey) and I just do not have the time for all of this.
RAWR! Does anyone know what to do? Please? S.O.S.?

Possible scenarios:
1: The 10.6.3 SL retail disk is bad, it happens.
2: Your not using the 10.6.3 SL retail disk but one from another machine which doesn't have the drivers for that machine.
3: Your optical drive is funky or some other hardware issues.
4: Your trying to install 10.6 onto a PowerPC based Mac, no can do.
5: Your not using a wired keyboard for boot key commands, have some other hardware conflicts.
Possible solutions.
1: Copy the SL 10.6.3 disk using Disk Utility to another DVD, the error checking may resolve the original disk's issue.

2: Make a SL bootable USB

3: Call Apple for a new 10.6.3 disk (and make copies for backup before Apple discontinues selling it)
If your upgrading to 10.6 to get to 10.6.8 to upgrade to 10.7, be warned of this:
1: Your 10.5 software will not work in 10.7, no more Rosetta or PPC based code.
2: Your hardware will not qualify if it's a 32 bit Intel Core Duo, also you may experience slowdowns in performance over 10.6 (10.6 is the fastest OS X version for Intel Macs) in older Intel hardware (I suggest Early 2011 Mac's and later only for Lion)
3: Mountain Lion 10.8 is reportingly coming out this summer and will not run on a lot of older Intel based Mac's because of heftier graphics requirements.
4: 10.6 has the widest range of current avaialble software and drivers for third party hardware.
My advice, stick with 10.6.8 and stay there, buy a new Mountain Lion machine after this summer. Skip Lion completely.

My HD needs to be reformatted according to Disk Utility, but even when I use an external device for startup, Disk Utility cannot reformat the HD

I have a Macbook with a 500 GB Hard Drive. A routine check on Disk Utility told me the disk needed to be reformatted. I restarted from an external USB drive, but when I try to use Disk Utility to repair the HD or to reformat it, Disk Utility is unable to do anything with the HD (cannot repair, cannot erase,cannot reformat the HD). Is there a utility App that can help me with this, or is the HD unrecoverable?

Hi
Thanks very much for your reply. We have been starting up from a backup (USB) drive and use the disk utility that is on the backup drive so the internal (problem) HD is not being used for anything (except for wanting to repair it). Still Disk Utility cannot reformat or repair the drive. I have also run Onyx but it tells me everything is OK on the drive.
But I have made a little progress. Using my old install disk for Snow Leopard (10.6.3) I have managed to do a fresh install of the system on the internal HD. Unfortunately, I also asked the install disk to transfer/migrate the settings and documents from the backup drive back onto my internal HD. The install appeared to work, but then it got hung up on copying the documents from my backup drive to the HD. After letting it sit for 2 days without going anywhere, I stopped the install process. I am going to try again, just using my Snow Leopard CD to install Snow Leopard, and nothing else. If that works, I will then get on to the problem of copying the rest of the settings and documents from my backup.
But since the Mac works OK off the USB backup, and will also run off the install CD, I am guessing the problem is with the HD and the only solution might be to replace it if I can't repair it. But the macbook is several years old, and I am not sure it is worth buying a new HD for it.
