WD My Book 1TB and Snow Leopard

I've installed Snow Leopard on two Macbooks, and now neither one of them can read my WD My Book 1TB External Drive. It says "Invalid index key", and disk utility tries to rebuild the "catalog B-tree" but fails. The drive is 3 months old at most. It will show up in Disk Utility, but it won't mount so that you can see data.
HELP!
Suggestions are most welcome. I have 500gb of data on this puppy that I really really really don't want to lose...

Hello.
I've installed Snow Leopard on my brand new Macbook Pro, and I had EXACTLY the same problem, not on one, but on TWO of my external Hard drives! One of them several years old connecting in IDE, the other one only a few days old, connecting in SATA! Both of them are Seagate's 500GBs.
I'm running a data recovery software right now, and it's working this back, but since it happened on two completely different disks in such a short period of time (less than a week), and since it looks like other people are having the same problem, I'm beginning to wonder if there isn't a deeper problem in the way Snow Leopard is handling the external Hard Drives...
I'm now pretty scared to connect my others Hard Drives to this computer, cause I don't want it to turn them all down! Maybe I'm just cursed, but the coincidence would be really big!
Are there other people experiencing the same problem? I'm wondering if there aren't others who didn't bother speaking in here, because blaming the hard drive would look like the most logical thing to do, like you just did in this thread, so most people wouldn't think of anything but bad luck for that...
And are there any way to check if there are more occurrences of this specific problem under Snow Leopard, or to check directly if there isn't a problem in the way Snow Leopard deals with external Hard Drives?
I'm looking forward for a third hard drive to fail. I'll tell you if this happens.
Cadwallader.
PS : The oldest of the two Hard Drives worked as external under Tiger for three year, never had a problem...

If a photo is returned to me in a reply does it use additional storage? I am using Mac Book Pro w snow leopard 10.6.8 and an iPhone 4s iOs 5. Yes, eventually I'll free up time to update these. Thanks.

Uh uh, I see!
Also it seems I can use my time machine backup:

together with Migration Assistant. This would work. Thanks
Now I need to figure out the Windows part. I need a full backup of Windows as well, with all the programs. In particular I need to be sure I can maintain the graphic card drivers.
You don't want to know how long took for me to find out how the **** I could update my graphic card drivers in Windows on my Macbook pro. Unfortunately there was a lot of misleading propaganda from Apple about bootcamp, saying that the new intel processor would have worked fine with Windows. Sad that everything was a lie. When installing Windows with bootcamp the graphic card program was unable to find and install the graphic card drivers update . Took me 2 weeks reading through thousands of angry posts of disappointed costumers to find out how to do that. I do not want to reapeat this dreadful experience.
After one year and a half with my Macbook pro I have a system I am TERRIFIED to touch. It is very very fragile, and any little change can destroy everything. It barely works. that's why I am so scared to re-install the OS

You can get replacement System Install & Restore CD/DVDs from Apple's Customer Support - in the US, (800) 767-2775 - for a nominal S&H fee. You'll need to have the model and/or serial number of your Mac available.

Shared printing and snow leopard

I can't get my 2 mac books to print on the shared hp laserjet 1320 that is connected to my iMac. One mac book is running snow leopard and the other is running leopard. The iMac is running snow leopard. They printed fine before the upgrade to snow leopard. I have checked shared printer on all computers. The iMAc says everyone can print on the shared window. The firewall is turned off. The error message says authentication required. When I click on resume it asks for a user name and password. I have tried to add a user to the iMAc and then use that on the mac book but that does not work either. I talked to someone from HP today who referred me to this forum for help. Any ideas?

Bonjour is the protocol used by all recent versions of OS X to see shared printers. I don't have 10.4 but I do have a PowerMac G5 running 10.5.8 and it can see the shared printer on my MacBook Pro running 10.10.1. So I wonder if there is something about Bonjour in 10.4 or if you have some other network issue?
From the PowerBook, are you able to see and connect to a shared folder on the iMac?

Home Sharing between Mountain Lion and Snow Leopard

Hi
I have MacBook Pro both at work and at home. The one at work has Mountain Lion with the latest version of iTune and the one at home has Snow Leopard with iTune 10.7.
I want to share movies on my iTune account between Mountain Lion and Snow Leopard. However, it doesn't seem to work....
How can I solve this problem?
FYI - I am not a big fan of Mountain Lion and do NOT want to upgrade my home computer to Mountain Lion.

    I am not sure why you can't access iCloud, using a browser? Then you have the same address book, so long as you are connected to the internet. https://www.icloud.com/
    No email involved. From the browser, you can download individual iCards or all of the individual cards, BUT unfortunately, not the Groups. So, you have to fiddle on the SL machine with keeping the groups organized.
    Up until recently, I have been able to sync Contacts from ML (which stays synced to iCloud) to SL this way: copy the /Users/~/Library/Application Support/AddressBook/ folder from the ML computer to the SL computer by dragging the icon onto the dock's AddressBook icon, this should retain all the group info. But, recently, this has ceased being complete.
    Apple really left us behind on this one.

I just upgraded my mac book pro to snow leopard, now my I photo library dissappeared

I am a novice in all things technical and I need some help figuring out my I photo library. I bought my Mac Book Pro in 2009 and shared/transferred all information from my G5 (2004) to my laptop. I Photo was also transferred and I have started to add more photos to this laptop.
I just upgraded my mac Book Pro to Snow Leopard and now when I open my Iphoto library it shows some of the library but now all. My husband said it is still there but the system is not able to look in the right place due to the sharing...so I am totaly confused?????
WHen I go to the Information it syas it is Where: /users/shared
Under sharing and permission it says: You have custom access
vivianlie read and Write (but this is in light gray)
Everyone (also in light gray)
NOW: My old and faithful G5 all of a sudden is telling me this morning that in order to open I photo I
need to upgrade to work with this verion of I photo
Your photo library will not be readable by previous versions of I photo after the upgrade.
What should I do now?
Thanks so much for any tips and ideas...

On you MBP try the three fixes below in order as needed:
Fix #1
1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your Home/Library/Preferences folder.
2 - delete iPhoto's cache files that are located in your Home/Library/Caches/com.apple.iPhoto folder.
3 - reboot, launch iPhoto and try again.
NOTE: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding the the Option key. You'll also have to reset the iPhoto's various preferences.
Fix #2
Launch iPhoto with the Command+Option keys depressed and follow the instructions to rebuild the library.
Select the options identified in the screenshot.
Fix #3
Using iPhoto Library Manager to Rebuild Your iPhoto Library
Download iPhoto Library Manager and launch.
Click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option
In the next window name the new library and select the location you want it to be placed.
Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments but not books, calendars or slideshows. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.
On your G5 make a temporary, duplicate copy of the library and run the same 3 fixes.

Import contacts from old address book on MacBkPro Snow Leopard into new MacBk Pro Lion

How do I import my contacts from old address book on MacBkPro Snow Leopard into new MacBk Pro Lion (on MacBkPro Retina). I can see the "AddressBook" file on the old HD (extracted from old machine--which died) and have a copy of that file on to desktop of new machine. [Copied from old HD: Users/home/Library/Application Support/Address Book]. There is an Address Book in the same location on the "MacIntosh HD" of the new machine, but some of the files in that (new) folder have different names. Risky to simply over-ride this. What should I do?

My mistake - my groups are there! They transferred perfectly. Still getting used to my wonderful new machine. Sorry to bother you!

In limbo between Leopard and Snow Leopard - stupidly didn't back up

I've got an old-school black MacBook, about four years old now. I never cared enough to upgrade it to Snow Leopard, but now I want Lion. So, I borrowed my parents' five-license Snow Leopard install disc and started off on the journey to upgrade to Snow Leopard, download the App Store update, then download and install Lion. I didn't get far.
First, let me say that I didn't back up my hard drive. Like an idiot. Yes, I know it was stupid, so there's no need to say anything. My previous installs (a few clean re-installs) have gone without a hitch, so I figured I'd trust Apple and just run the installation without backing up. Dumb.
The Snow Leopard installation started fine, but was interrupted when the installer said the install failed. Restart, try again. Booting from the install DVD, things seemed to be going fine a second time around -- picked my language, got to the install set-up screen, picked Macintosh HD as my installation drive. And then things stopped working. The installer said my HD could not be written to and that it needed repair. So I went to Disk Utility to try that. Repair Disk wasn't available, so I clicked Verify Disk. That got interrupted when it said the disk needed to be repaired, after which the Repair Disk button was clickable. Tried to repair, but apparently my HD is screwed beyond the capabilities of Disk Utility.
I tried to reboot the MacBook from the HD, which Disk Utility said still had Leopard running on it. The computer wouldn't boot up. Safe Boot didn't work. So, without any other real options, I thought I'd try my luck by just trying the install again. Booted up from the install DVD, and ran into the same issues. Didn't magically fix itself, of course. So my MacBook is stuck in limbo between Leopard and Snow Leopard, won't boot from the HD and won't let me repair the disk when booted from the DVD. What do I do?
I plan to try a couple third-party disk-utility programs tomorrow (8/25/11) to recover the files on my HD. There's not much I care about on there (just some iPhone photos and my resume, really), so doing a clean wipe of the HD and installing Snow Leopard is an option. But I'd of course rather be able to recover my personal files. Is this possible at this point?
Another question I have regarding a clean wipe: If I end up having to clean off the HD and lose all my data, I'll lose the iTunes configuration for my iPhone. Will iTunes be able to import my apps and settings from my phone if I plug it in?
Thank you very much.

I tried copying a photo and pasting it in another event/group within iPhoto but the paste feature doesn't work. This wasn't an issue with both Leopard and Snow Leopard. Do you have any solutions or tips?

I bought a new MacBook Pro with OsX Lion as operating system. I use iPhoto a lot and when I tried copying a photo then pasting it to another event/group, the 'paste' feature doesn't work. This wasn't the case with Leopard and Snow Leopard where the 'paste' feature worked. What I did was to paste the photo first to the desktop before transferring it to the new event/group. I brought my Mac to the Apple store where I bought it and the technicians were themselves surprised that the 'paste' feature didn't work. Chalked it up to glitches in the Lion os. So how do we fix this? I just find it absurd that a feature that used to work in Snow Leopard has been disabled in Lion, and the user still has to undergo an additional step to make it work, when new technology is supposed to make things easier for users.
Also, hasn't anyone noticed that it takes longer for the computer to boot upon opening?

Instead of copy and paste drag the photo to the new event. Or flag it and use the add flagged photos to selected event command

Alternatively, partition your internal HD and dual-boot it. Do note that you have to reboot to switch back and forth. You can't do it by logging out and back in.

Is it possible to install Lion on the second hard disk on my Mini (2010) Snow Leopard Server, and switch between Lion and Snow Leopard? I like those voices Lion has in speech.

Is it possible to install Lion on the second hard disk on my Mini (2010) Snow Leopard Server, and switch between Lion and Snow Leopard? I like those voices Lion has in speech.

When baltwosaid NO emphatically, that was described as CORRECT ANSWER. Ditto in the caeses of the radically different answers from Camelotand Matt Clifton
Could it be that CORRECT ANSWER needs better defining by Apple?
That apart, yes, switching might involve rebooting. About the voices, well, I was the other day adding voice to a commentary in a video I was working on. There's only American English accent in SL — Lion I believe has British ones as well.
Why not, I wondered, try to install Lion purely for academic interest, maybe with an SD card (Sandisk Ultra II, 16GB) as Tom Nelson says is possible at http://macs.about.com/od/macoperatingsystems/ss/Perform-A-Clean-Install-Of-Os-X- Lion-On-Your-Mac.htm

Aperture 2 and 3 and Snow Leopard

My system with Aperture 2 was perfect.
Then I believe that Snow Leopard killed Aperture 2.
When I first installed Snow Leopard my machine felt like new again but slowly and slowly over the last few months the whole system seems to feel less and less snappy.
I don't use many video-intensive applications - my main one is Aperture 2, so this is where I find my main cause for concern.
Painfully slow adjustments with lagging, beach-balling, CPU-hogging, and RAM theft.
The main culprits seem to be Highlights/Shadows, Straighten, Crop, and Retouching… although my open mind says that could simply be because they form the latter part of my tweaking process.
There seems to be a thumbnail generation issue. Every adjustment that is made generates a new thumbnail - as you work through your tweaks that process seems to get backed up and slow everything down.
There seems to also be a video issue. Tweaking horizontal photos in full screen causes twice as much lag as a vertical image. Why? Take a look - it's obvious - in full screen edit a vertical image is about half the size of a horizontal one.
There seems to be a memory issue. Aperture seems to use a large amount of processor and RAM and sometimes doesn't let go of it or it gets caught in some kind of a loop. I've no idea what I'm talking about here. All I know is when I look at Activity Monitor the numbers are going through the roof and I can barely concentrate on them because of the noise from my fans.
There have been various and quite diverse suggestions on this and other forums as to what the underlying problem is and I have done my best to look into those and see what can help.
I have an early-2008 MBP 4,1 - 2.6 Intel Core 2 Duo - 4GB (factory-fitted) RAM - GeForce 8600M (512MB) GT.
I have done everything possible: all software totally up-to-date, re-installed combo updates, rebuilt Aperture libraries, run consistency checks, fresh Aperture install, fresh Snow Leopard install, repaired permissions, booted in 32bit, booted in 64bit, run hardware tests, deleted plists, cleared caches, downloaded and run applications like Onyx and Snow Leopard Cache Cleaner (amongst others) to ensure everything is in ship-shape along with various test applications to gauge if components like my hard drive are dying.
I keep my system clean and tidy. I have now stripped out bloat. I even took out iPhoto in case its 'iLife' browser link to Aperture was an issue. I have 85GB free on a 200GB. All components are original as factory-fitted by Apple.
Everything that any seemingly intelligent person on any decent forum has suggested has been done - in particular I thank the many users here on the Apple forum for all their information sharing… I try to read them all.
From what I see on the forums, I am not alone.
Nothing has fixed this problem.
I (and no doubt many others) have fed this information back to Apple.
Aperture 2 and/or Snow Leopard has a problem that has not been fixed.
Aperture 3 got released and I trialled it and swiftly uninstalled it because the exact same problems are there - even with one single photo in it.
My concern is that Apple will not fix the cause of the problem which seems to lie outside of Aperture.
If Apple concentrate on making Aperture 3 work better inside a possibly shaky Snow Leopard then I will be very disappointed.
I'm not forking out for a new version of software just because Apple broke my current software. Don't get me wrong - I do actually WANT to buy Aperture 3 because it has functional improvements and advancements that I would love to be using providing it works properly - and for me (and it appears for 'quite a few' others as well) it just simply doesn't… and neither does Aperture 2 any more.
I am no technical expert (as you've probably noted already) but a MAJOR bug seems to lie in the relationship between Snow Leopard, graphics cards, and the way it handles memory - and so in turn graphically-intensive applications like Aperture are high-lighting these problems more than others.
I am sure there are people without these problems. Perhaps these problems relate to specific hardware configurations. My configuration is Apple standard. I really shouldn't have these problems.
Until Apple fix this major bug I cannot remotely consider Aperture 3.
Until Apple fix this major bug I could never buy Apple again.
Up until Snow Leopard you had a VERY happy camper. I had a perfect machine and I was shouting Mac from the rooftops to anyone that would listen.
And then it seems Snow Leopard broke my machine.
What a shame.
I really want to use Apple, I actually really like Snow Leopard, I really want to use Aperture, I really want to carry on telling people how wonderful the Apple Mac experience is (or was...) but Apple are currently making it very difficult for me to continue doing so.
Please fix Snow Leopard.
This will hopefully fix Aperture 2 and Aperture 3.
Unless anyone else has a fix?
Sincere apologies to all for banging on for so long !!

Thanks for your input setwart.
When I make adjustments I do want Aperture to provide me with a new version so that I can see the original image and also that I have a version which I have already adjusted. I've previously tried changing that preference before with no improvement in performance unfortunately, but it's not really what I was referring to.
Versions, thumbnails and previews were very confusing terms to me for a while… actually, in some ways, they still are but my understanding is 'a little' better now.
That said, I probably used the wrong term.
What I meant was that every time you make an adjustment Aperture seems to produce a 'record' or 'snap-shot' of your image including that latest adjustment. In so doing you have an entire history of each adjustment you have made. In my head I picture this like a movie film-strip with each frame differing slightly. You increase your saturation by a single point? Another snap-shot. Fancy another single point on your saturation? Another snap-shot… and so on.
It is typical that I will make a bare minimum of 20 adjustments on each image, and that's before even thinking about straightening, cropping, and retouching… and then maybe I'll go back and tweak everything again !!
Somehow, my system is having difficulty in keeping up to speed with all of those snap-shots of individual adjustments. Certain adjustments will drastically slow things down more than others, and then I get to play with the beach-balls.
But - it used to handle these things just fine and that's what I'm trying to get back to.
Thanks again for getting involved.
