Unmounted internal HD when running Snow Leopard.

Hi guys!
So I am studying in Milano Italy, Graphic Design. Yesterday in school I was working like normal. Suddenly the warning sign of a unmounted disk came up. The only problem was that I didnt have any connected USB or drives. I pressed ok. Then the computer freezed. I turned it off. Turn it on. A Apple and the animated time-circle came up. I didnt start for 15 min so I turned it off again. Turned it on. The critisizing folder came up with the question mark. I looked around on forums to see what it was. After turning the computer on and off after that time, I have NOT seen it again. I´ve tried to use all commands I could find so far with reseting PRAM etc.
The only thing is that I cant start up with holding the key C, I have to hold Alt and have the installation DVD mounted. Then choose the DVD installation disk. Inside the DISK UTILITY I can see my Macbook Pro HD, but it´s grey and not mounted (should have to do with something when the system told me I unmounted a disk incorrectly).
I can do Verify and Repair disk. But not with Verify and Repair Disk Permission, they are grey and cant be pressed.
So the Repair and the Verify says the Macbook Pro HD seems to be ok. So it´s all green.
When I try to mount the Macbook Pro HD it says "Macbook Pro HD cant be mounted try to Verify and Repair Disk before mounting.".
I cant start it up at all, just with the DVD Installation disk I can enter Disk Utilities, and from here I need help.
Anyone have something I can try?
One more thing is that when "Coninue" the installation, the hardrive doesnt appear in the feild of "Where the Operative System" should be installed. I cant continue either.
// Thanks a lot

Welcome to Apple Discussions!
From your description, it sounds like the hard drive is failing. Have you tried booting to the Apple Hardware Test and running the extended version? It may give you an error code that would confirm what the problem is.
The average useful life of a hard drive is 3-5 years, but some do fail sooner. Are you under warranty? If so, you may be able to get a replacement drive under warranty. If not, it is not too difficult to replace it yourself. You can find instructions at ifixit.
Good luck!

How can I synch iCal with iPhone when running Snow Leopard?

I'm running Snow Leopard (10.6.8), and I cannot upgrade to Lion or Mountain Lion because I have an Intel Core Duo iMac.
I absolutely MUST be able to synch my desktop calendar with my iPhone. This is an essential function for my life - I cannot believe that Apple would make me buy an entirely new computer, just so that my desktop calendar sychs with my iPhone.
Can some please help me figure this out?
Thank you!!

Maybe you might get more response in the MobileMe forum as it sounds like an issue with that to me and I don't use it so am unable to help in that area.
Hope you get it sorted out soon.

I have a new l7 macbook pro running snow leopard. When I try to boot into windows7 32bit, I get either a blue, black, or flickering screen. Then I have to physically shut down and try again. At that point it will load correctly. Any help?

I have a new l7 Macbook Pro running snow leopard. When I tried to to install windows 7 32 bit on bootcamp, I kept getting a flicking black and blue screen when it tried to install. (Tried several times). I finally downloaded the bootcamp windows support to a flash. I inserted that and finally got it installed. Now when I try to boot into windows I get either a solid black (sometimes blue) or flickering screen and windows will not start up. If I then physically shut down the mac and restart, it will finally boot into windows where it tells me that windows was shut down unexpectently and once I click start windows normally, it will boot up. That will generally let me boot into windows for the remaining of the day. The next day, the same thing happens again. I have tried reinstalling several times, and the same thing keeps happening. It is not my windows disk because it installs flawlessly on the mid 2008 macbook pro. Anyone know how to fix this?

Thanks Dirk,
Tried your suggestion various ways but it had no effect the download button was still greyed out and the install button would not activate will keep trying to find a solution. I dont want to boot from the external hard drive that has Lion on mainly because it is a usb HD and the connection to my wireless modem slows the connection rate and downloading would take about ten hours

I just installed the new mountain lion software on my iMac. I was currently running Snow Leopard. My problem is with my mouse. Now when I scroll down the page it moves in the opposite direction. I checked system S.P. - Natural for scroll feature.

I just installed the new mountain lion software on my iMac. I was currently running Snow Leopard. My problem is with my mouse. Now when I scroll down the page it moves in the opposite direction. In system preferences I tried checking and unchecking Natural for scroll feature. Movement from side to side works fine. Has anyone experienced this problem?

I think this new scrolling behaviour was introduced with Lion. You do get used to it pretty quickly (well I did). Are you sure that deselecting Natural Scrolling in Mouse Prefs doesn't re-instate the previous behaviour, it does here.

You stated; " I have been successful with My Power Mac "
A Power Mac is incapable of being upgraded to Mavericks. It is a PPC Mac which can only run versions of OS X up to 10.5.8 and no higher. Any version of OS X higher that 10.5.8 requires an Intel processor to run.
Does the iMac meet the hardware requirements for Mavericks?

Just downloaded FACETIME on my 4yr. olf Imac running Snow Leopard. When making a call to my friend's Imac all works correctly going both ways. When my wife calls me via Facetime from her Ipad, I cannot click on "accept"- not there? When called by the Imac (newest), the "accept" or "reject" radio button appears for me to click and connect. On my wife's Ipad the two radio buttons always appear when a call actiivates Facetime and comes on?
There is nothing I can find in "Preferences" in Facetime to turn that on or off. I suspect it has to do with having a more current operating system; that the "controls" are in the operating system? [I'm guessing] It's frustrating getting Facebook calls from several friends on Ipads! Any ideas...VFP

I suspect it has to do with not having a more current operating system
Exactly, what Apple is doing is leveraging new features only on newer OS X versions to force you to upgrade OS X to 10.7 or later.
What they don't tell you is 10.7 or later will NOT run your PowerPC based software, some of it you can't get Intel versions like for perfectly working printers, scanners and games etc. So it can be a very expensive OS X upgrade to 10.7 or later with third party software.
http://roaringapps.com/apps:table
Also they don't tell you is the risk in bricking your machine if the update goes badly, so you have to have AppleCare in case that occurs so it's on them to fix it. Else your paying money to replace the logicboard or buying a new machine prematurely.
A four year old machine can't have AppleCare, it's only good for 3 years from date of purchase new.
Your machine came with a boot hard drive, it's usually got about 4-5 years of life on it, then it needs to be replaced.
Also they don't tell you the newer OS X version has more abilities and features that causes your machine to slow down in performance, especially on older machines.
Also they implement new, idotic and extremely fustrating new user interface features in a arbitrary "you take it or leave it" manner with little or no fall back method.
So upgrading OS X is a gamble on older machines that otherwise would likely work perfectly fine for the next 5 years if one didn't need to have to mess with it.
Since Snow Leopard has slightly over 25% OS X version market share, your still good for security updates etc for the next few years if you just want to stay where your at and be happy.
OS X 10.4/10.5 need to upgrade, 10.6.8 ok still
The Lions are, well, not so welcome due to Scott Forstall retard UI issues, OS X Mavericks 10.9 is likely going to fix things a bit better.
But basically what is occuring is Apple is trying to force a faster hardware upgrade cycle with the more expensive products by leveraging features on the smaller devices that expire sooner.
Apple is a hardware company that leverages whatever it can to get you to buy more hardware, it's why they are as rich as they are.

That would at least partially explain it.
These MacBook Pros drew more power than the power brick could readily supply, and so would only run at top speed when the power brick was supplemented by the battery.
Though the applicable tech note has been removed, it stated:
"If the battery is removed from a MacBook or MacBook Pro, the computer will automatically reduce the processor speed. This prevents the computer from shutting down if it demands more power than the A/C adapter alone can provide."

If you look at the User Tips tab, you will find a write up on just this subject:
https://discussions.apple.com/docs/DOC-4053
The subject of buying/selling a Mac is quite complicated. Here is a guide to the steps involved. It is from the Seller's point of view, but easily read the other way too:
SELLING A MAC A
Internet Recovery, and Transferability of OS & iLife Apps
Selling an Old Mac:
• When selling an old Mac, the only OS that is legally transferable is the one that came preinstalled when the Mac was new. Selling a Mac with an upgraded OS isn't doing the new owner any favors. Attempting to do so will only result in headaches since the upgraded OS can't be registered by the new owner. If a clean install becomes necessary, they won't be able to do so and will be forced to install the original OS via Internet Recovery. Best to simply erase the drive and revert back to the original OS prior to selling any Mac.
• Additionally, upgrading the OS on a Mac you intend to sell means that you are leaving personally identifiable information on the Mac since the only way to upgrade the OS involves using your own AppleID to download the upgrade from the App Store. So there will be traces of your info and user account left behind. Again, best to erase the drive and revert to the original OS via Internet Recovery.
Internet Recovery:
• In the event that the OS has been upgraded to a newer version (i.e. Lion to Mountain Lion), Internet Recovery will offer the version of the OS that originally came with the Mac. So while booting to the Recovery Disk will show Mountain Lion as available for reinstall since that is the current version running, Internet Recovery, on the other hand, will only show Lion available since that was the OS shipped with that particular Mac.
• Though the Mac came with a particular version of Mac OS X, it appears that, when Internet Recovery is invoked, the most recent update of that version may be applied. (i.e. if the Mac originally came with 10.7.3, Internet Recovery may install a more recent update like 10.7.5)
iLife Apps:
• When the App Store is launched for the first time it will report that the iLife apps are available for the user to Accept under the Purchases section. The user will be required to enter their AppleID during the Acceptance process. From that point on the iLife apps will be tied to the AppleID used to Accept them. The user will be allowed to download the apps to other Macs they own if they wish using the same AppleID used to Accept them.
• Once Accepted on the new Mac, the iLife apps can not be transferred to any future owner when the Mac is sold. Attempting to use an AppleID after the apps have already been accepted using a different AppleID will result in the App Store reporting "These apps were already assigned to another Apple ID".
• It appears, however, that the iLife Apps do not automatically go to the first owner of the Mac. It's quite possible that the original owner, either by choice or neglect, never Accepted the iLife apps in the App Store. As a result, a future owner of the Mac may be able to successfully Accept the apps and retain them for themselves using their own AppleID. Bottom Line: Whoever Accepts the iLife apps first gets to keep them.
SELLING A MAC B
Follow these instructions step by step to prepare a Mac for sale:
Step One - Back up your data:
A. If you have any Virtual PCs shut them down. They cannot be in their "fast saved" state. They must be shut down from inside Windows.
B. Clone to an external drive using using Carbon Copy Cloner.
1. Open Carbon Copy Cloner.
2. Select the Source volume from the Select a source drop down menu on the left side.
3. Select the Destination volume from the Select a destination drop down menu on the right
side.
4. Click on the Clone button. If you are prompted about creating a clone of the Recovery HD be
sure to opt for that.
Destination means a freshly erased external backup drive. Source means the internal
startup drive.
Step Two - Prepare the machine for the new buyer:
1. De-authorize the computer in iTunes! De-authorize both iTunes and Audible accounts.
2, Remove any Open Firmware passwords or Firmware passwords.
3. Turn the brightness full up and volume nearly so.
4. Turn off File Vault, if enabled.
5. Disable iCloud, if enabled: See.What to do with iCloud before selling your computer
Step Three - Install a fresh OS:
A. Snow Leopard and earlier versions of OS X
1. Insert the original OS X install CD/DVD that came with your computer.
2. Restart the computer while holding down the C key to boot from the CD/DVD.
3. Select Disk Utility from the Utilities menu; repartition and reformat the internal hard drive.
Optionally, click on the Security button and set the Zero Data option to one-pass.
4. Install OS X.
5. Upon completion DO NOT restart the computer.
6. Shutdown the computer.
B. Lion and Mountain Lion (if pre-installed on the computer at purchase*)
Note: You will need an active Internet connection. I suggest using Ethernet if possible because
it is three times faster than wireless.
1. Restart the computer while holding down the COMMAND and R keys until the Mac OS X
Utilities window appears.
2. Select Disk Utility from the Mac OS X Utilities window and click on the Continue button.
3. After DU loads select your startup volume (usually Macintosh HD) from the left side list. Click
on the Erase tab in the DU main window.
4. Set the format type to Mac OS Extended (Journaled.) Optionally, click on the Security button
and set the Zero Data option to one-pass.
5. Click on the Erase button and wait until the process has completed.
6. Quit DU and return to the Mac OS X Utilities window.
7. Select Reinstall Lion/Mountain Lion and click on the Install button.
8. Upon completion shutdown the computer.
*If your computer came with Lion or Mountain Lion pre-installed then you are entitled to transfer your license once. If you purchased Lion or Mountain Lion from the App Store then you cannot transfer your license to another party. In the case of the latter you should install the original version of OS X that came with your computer. You need to repartition the hard drive as well as reformat it; this will assure that the Recovery HD partition is removed. See Step Three above. You may verify these requirements by reviewing your OS X Software License.

Disk format error running Snow Leopard

Hi all,
simply trying to erase/reformat a LaCie 350 GB external hard drive. I keep getting the error that the disk won't unmount. How can I get around this and does this mean I shouldn't rely on this EHD. I'm reformatting it to load up some video clips for a client.....
Thanks for any kind assistance! This MacPro is 2008, running Snow Leopard and FC 7. 10GB Ram, 3-1T drives internal.

You might do a Safe Boot too if the restart isn't enough, or if you installed software or if TimeMachine is trying to back it up (I know it tries with most drives unless you tell it not to, rather than ASK if user wants to!).

Optimal way to run Snow Leopard in limited fashion on Mini 2011??

Been browsing ways to run SL on new Mac Mini 2011. Have one on the way as replacement for 2009 mini running 10.5.8. I have an external firewire drive running Time Machine in one partition as well a 2nd large partition with little on it. For most of what I do, Lion and the new machine will be a great upgrade, but I still want to run Quicken 2006. Don't want to go to the hassle of trying to get SL on the internal drive of the new mini. Could I just update my current 2009 Mini to SL, back every thing up in TM, do a carbon copy of the SL system on the "unused" Firewire HD partition and the just boot up the new Mini from the external drive when I want to use Quicken? Just want to figure out the optimal way to do this without messing up my new machine when it's fresh from the package. Thanks for the advice in this and all the previous posts.

I haven't seen any tips on how to do this yet, but if you get really stuck, you can always run Snow Leopard Server under Parallels.
Typically when the products come out, they can't be downgraded to an earlier version of the system than what they came with. You could always try to see if you could find a Mac Mini 2010 cd, boot to it, then use an external drive to install that system to it, and see if it can boot your new Mac Mini.

Mac pro shipped with OS 10.73 able to run snow leopard

I'm trying to salvage my old power PC applications and am hoping I will be able to run them if I load Snow Leopard. My mac pro is a 2 x 2.4 GHZ quad core xeon mac with 10.7.3 shipped loaded. Is there a way to run OSX 10,5.8?. will booting in 32 bit mode help with the old apps?

How To Run Snow Leopard On A New Mac
This does not apply to new Mac Minis or MacBook Airs. When newer models are introduced that also require Lion for hardware support, the techniques described below will no longer work with the possible exception of using Parallels 7.
What has to be done:
Create a new partition on the hard drive.
Get a clone of a 10.6.8 Snow Leopard system. Put the cloned Snow Leopard system onto the new partition.
Step One: Create a new partition on the hard drive
To resize the drive and create a new partition do the following:
1.           Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
          After the main menu appears select Disk Utility and click on the Continue button. Select the hard drive's main entry then click on the Partition tab in the DU main window.
2.           You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.
3.           In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed. (Note: You can only make a partition smaller in order to create new free space.)
4.           Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.
You should now have a new volume on the drive.
It would be wise to have a backup of your current system as resizing is not necessarily free of risk for data loss. Your drive must have sufficient contiguous free space for this process to work.
Step Two: Obtain a clone of a Snow Leopard system:
You will need access to a Mac already running Snow Leopard. You will need a 16 GB USB flash drive or an external hard drive to which you can clone the Snow Leopard system from the Mac that has Snow Leopard installed. Alternatives are:
Option One:
Install a new Snow Leopard system onto a USB flash drive. Boot the Mac used for installing with the USB flash drive. Update the flash drive system to 10.6.8 using the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard. Verify that you can boot the Mac with the USB flash drive.
Take the USB flash drive to your new Mac and try booting from it. If it works then clone the system from the flash drive to the newly made partition:
          Clone using Restore Option of Disk Utility
Open Disk Utility from the Utilities folder.
Select the destination volume from the left side list.
Click on the Restore tab in the DU main window.
Check the box labeled Erase destination.
Select the destination volume from the left side list and drag it to the Destination entry field.
Select the source volume from the left side list and drag it to the Source entry field.
Double-check you got it right, then click on the Restore button.
          Destination means the new partition on the internal drive. Source means the USB flash drive.
Option Two:
If you have a large enough external drive you can erase and use, then it would be easier to just clone the entire Snow Leopard system from the source Mac computer to the external drive.
          Clone using Restore Option of Disk Utility
Open Disk Utility from the Utilities folder.
Select the destination volume from the left side list.
Click on the Restore tab in the DU main window.
Check the box labeled Erase destination.
Select the destination volume from the left side list and drag it to the Destination entry field.
Select the source volume from the left side list and drag it to the Source entry field.
Double-check you got it right, then click on the Restore button.
          Destination means the external drive. Source means the Snow Leopard Mac's internal drive.
After cloning verify that it will boot the source Mac. If so then take the external drive to your new Mac boot with it. If all is well then restore the clone to the new partition on your new Mac:
          Restore the clone using Disk Utility
Open Disk Utility from the Utilities folder.
Select the destination volume from the left side list.
Click on the Restore tab in the DU main window.
Check the box labeled Erase destination.
Select the destination volume from the left side list and drag it to the Destination entry field.
Select the source volume from the left side list and drag it to the Source entry field.
Double-check you got it right, then click on the Restore button.
          Destination means the new partition on the internal drive. Source means the external drive.
If the above seems too daunting then you might consider running Snow Leopard inside an emulator such as Parallels 7. You are permitted to install a single copy of Snow Leopard inside a virtual machine. You will need to first purchase a copy of Parallels 7 and install it on your new Mac. Create a new virtual machine configured for Mac OS X. You may then install Snow Leopard in the virtual machine then download Mac OS X 10.6.8 Update Combo v1.1 and update to 10.6.8. Be sure to include Rosetta in your initial Snow Leopard installation. Rosetta is not installed by default rather it's an optional install.

I have a MacBook Pro (15-inch, Late 2008) and am currently running Snow Leopard 10.6.8. I would like to know which is the most stable upgrade for my model. I have read some reviews of Maverick and Yosemite making the older macs slower. Is this true?

I have a MacBook Pro (15-inch, Late 2008), Intel Core 2 Duo 2.53 GHz, 4GB Memory. and am currently running Snow Leopard 10.6.8.
I would like to know which is the most stable upgrade for my model? Mountain Lion, Mavericks or Yosemite?
When I had gone to the apple care centre in India a few months ago to upgrade my OSX to Mountain Lion, I was told that considering my macbook pro's specs, upgrading it would just make it less efficient, and that I should stick to Snow Leopard unless I consider buying a newer mac that would benefit from it. Is this true? I find it a bit hard to believe. Which update is most recommended?
I also notice that my mac has gotten considerably slower. While using chrome, it buffers and struggles with even just 5 tabs open. Could this have something to do with my current ios? As a precaution, I have always been making sure I have enough free space on disk i.e around 70 - 100 free out of 250GB.
Any advice is appreciated.
Thanks in advance.

Mavericks is no longer available from the App Store, so your choice is Yosemite. One option is to create a new partition (~30- 50 GB), install the new OS, and ‘test drive’ it. If you like/don’t like it it, you can then remove the partition. Do a backup before you do anything. By doing this, if you don’t like it you won't have to go though the revert process.
Check to make sure your applications are compatible.

I have an IMAP mailbox that seems to only show mail 7 days old on my iMac running Snow Leopard.However, all old emails that I have not deleted are showing up on my macbook pro running the next OS (Lion?). How do I get all my old emails back on my iMac?

I have an IMAP mailbox that seems to only show mail 7 days on my iMac running Snow Leopard. However, on my MacBook Pro I can see all old mail that I have not deleted. It is running the next operating system (Lion?). Does anyone know how I can get all my old mail back on my iMac. It is my primary computer and I need some of those old messages. I have tried to rebuild the mailbox but it has not done anything.

I have tried to rebuild the mailbox to no avail. The mailbox behavior says: Drafts (not checked) store draft messages on the server, Notes (checked) show not in Inbox, Sent (checked) Store sent messages on the server Delete sent messages when (option never selected), Junt (not checked) store junk messages on the server Delete junk messages when (option never selected), Trash (checked) moves deleted messages to the Trash mailbox and (checked) store deleted messages on the server Permanently erase deleted messages when (one month old option selected).
I have not set up any rules that I know of other than a signature, in the very least I have not changed any.

Cloned HD running Snow Leopard won't boot in new MBP running Lion., cloned HD running Snow Leopard won't boot in new MBP running Lion.

Hi, I've seen a lot of discussion on this topic but nothing specific to my situation. I have two macs, a personal mac (macbook running Snow Leopard vers. 10.6) and a newer work macbook pro (late 2011 running Lion vers. 10.7.5). I want to use some of the applications at work (that is on the Macbook Pro) that are on my home macbook with Snow Leopard. I cloned the entire HD of my Macbook onto an external drive. The clone seems to have worked as I can use it as a boot disk for the macbook (from which it was cloned). However, if I try to boot the MacBook Pro running Lion, with this same clone on the external drive it won't work. I get a bit of text in the background and an overlay in dark grey saying (in several languages) restart the Mac by holding down the start key etc. I don't know if this has to do with the kernel panic problem or the Lion restore disk business. I don't see the point in trying to do an internal partition of the MacBook Pro hard drive and then add the cloned Snow Leopard, if I can't get the thing to boot externally as it is.
Does anyone have any fixes for what really should be a simple proceedure but is not?

Make sure the mac you are cloning from has the combo 10.6.8 update applied to it. The late 2011 models need at least 10.6.7 and better with 10.6.8. So if your older mac is running anything lower than 10.6.7 it will not boot on the 2011 model.
