2 T internal drives?

How well does the Mac Pro handle 4x 2T internal drives. I currently have 4 X 500 GB Intel drives and 4 X 2T G-Raid external drives. I would love to bump up the internal storage now that my warranty is ending. Any advise?

I always keep spare drives, and use SuperDuper to keep images even of drive volumes.
Keeping one drive to OS only and no data or prefs helps.
Having an emergency drive or partition: a must (sort of like Micromat TTPro eDrive only better).
Pull the drive for now. Maybe Data Rescue II later. And a FW case you can throw it into for repairs or to recover files.
I am surprised you don't get the "stop" sign, a circle + slash, that often indicates corrupt journal/directory and no boot device where it expects to find one.
TechTool Pro, commercial $90 5.0 is due soon, hopefully they were just waiting now for 10.5.5 to be out and see if it would change or alter (or break) their utility.
Backups, whether TS or a clone made with SuperDuper, are critical, should run on their own automatically in background, and the OS doesn't have to be that large, fit it on 60-100GB disk image so you don't have to worry about partition and size.
For now, use the DVD to install OS X on a new drive partition to begin to build a foundation from which you can do more and mark this as emergency-only. You can clone it later if needed to a "working" system. SuperDuper is free for full copy, or use Disk Utility Restore even to set the source and 'target' destination volumes.

Locked out of additional internal drives... Help please

Any help would be more then welcomed as I did something stupid and need a bit of help to fix it please.
Had an issue today on my Mac Pro (2.8, Quad 5.1). All was running fine until I went to update a piece of 3rd party software (Fetch). After the download I went to drag new version into my apps folder and was told I didn't have permission to instal the app.
Now to be clear, I've had a bit of an issue with this before as I'm running 2 mac pros in different locations and drag and copy files and folders from here to there on a regular basis via FTP and external drives. I also have all 4 slots filled on both systems with various drives set up for a particular function along with a number of externals. I've set permissions on both systems and all drives to "read and write" for both my accounts to have full access and each time "apply to enclosed items" was selected.
But for some reason, from time to time, I have to authorise the file transfer. Haven't figured out the reason but it's not a huge deal so have left it.
Today was the first time I have had access denied for my home folder when working from same system. Not thinking and while on the phone to someone (this is where I did the stupid part), I opened the info on my boot (startup) drive and decided to add both of my user accounts and change permissions for each in addition to the system, admin and everyone that was already there. This was done while working from it directly and then set options to "apply to enclosed items". Yea, smart I know.
About 20 minutes passed and then it told me that it didn't like any of my system extensions. I was forced to do a restart and got the spinning wheel for about 30 minutes. Had to do a force quit and open in single user. Applejack wouldn't help at all, nothing. Had to then open cd drive through terminal just to get systems disk inside.
Restarted from systems disk and tried a simple disk utility repair. System restarted fine but I noticed that I was then locked out of all of my additional internal drives, iDisk included (padlock shown on all drive icons excluding my Boot/Startup drive). Tried opening info on the various drives with apple i option and "permissions denied" popped up each time.
I then took the step to restore from time machine. Set my restore selection to about 2 hours before I became an idiot. After it was finished I restarted the system hoping that would clear up my mistake but same thing, still locked out of all of my drives aside from boot/startup drive.
All user accounts that I have added to the boot drive are still showing, I have yet to try and remove them... Figured I would ask for help before I messed it up any further. Spoke to apple care and they have advised me to do what I have done so far.
Aside from an erase and instal, what steps should I take from this point? Will removing the added accounts clear up the issue?
Also, any idea as to why I was refused permissions to begin with...?
Thanks in advance and sorry for the book, just wanted to be as clear as possible.

I had tried installing windows 8.1 pro with many different solutions like using Bootcamp or using gdisk part and upgrading the disk part from hybrid to EFI also tried Using Lenevo external Optical drive which doesnt worked my internal drive is damage

I Am fed up after getting error after errors on the installation of windows 8.1 in my late 2011 MBP 15" 750 GB HDD and OSX Yosemite 10.10.2 and i am trying to install windows 8 or 7 and the error doent go away also i tried various other methods like gdisk part to make next button appear and Afte next button appear i am getting the error after the check list is done
please someone help me out i am getting paranoid in this and i am going to be a threat to society because its making me insane.

1. You cannot use the Lenovo external drive, because you already have a built-in SuperDrive. Get your internal drive fixed.
2. Your Mac does not support EFI Boot, because it is a PreUEFI model based on How to identify MacBook Pro models - Apple Support and the following list. If you force it with EFI boot, some of your hardware GPU/Audio will not work properly.

ITunes keeps storing files on C drive, even when the library/storage is on another internal drive. It should stop that.

Whatever I do to get iTunes to store it's data and settings on another internal drive, it KEEPS some sort of data/settings stored on the C drive.
A mkdir has been set up already to catch nasty "keep doing that" behaviour. Nevertheless, iTunes dumps stuff on the C drive /documents/mymusic.
Without to receive a technical story (read: a SIMPLE solution that does not feel like a hack), what's the solution.
Why does iTunes not simply ask WHERE to store the files rather than "assuming that the user is stupid and we think for him" attitude.
managing a database or DRM isn't THAT difficult.
Whatever files are within the directory is absolutely fine, as long as the user is allowed to choose that directory.

Did you mean mkdir or mklnk?
By default the iTunes library is stored at C:\Users\<User>\Music. If you play with Windows so that your entire profile is stored on a different drive then the library will be stored inside the profile. If you have used the option to change the location of the media folder to point to another path then you've only changed where the content is stored, not the database and supporting files. In addition if you use this option with an external drive or network share and that location isn't ready when iTunes starts then it will reset the path to the media folder to the default location inside the library folder.
Generally the solution when setting out is to move the entire library to the root of a different drive and then shift-start-iTunes to connect to the library in this new location. See HT1589: iTunes: How to open an alternate iTunes Library file or create a new one
Since you didn't do that to start with, either start again, or see my post make a split library portable.
There is another chunk of data stored in the %appdata% section of your user profile. If you don't have any iOS devices you can ignore this, but if you have, and have an SSD system drive, then there is merit in relocating the ...\MobileSync\Backup folder to another drive with a mklnk junction/symbolic link as these backup folders can become quite large. Note that junctions/links should not be used to relocate sections of the main library as they will be unraveled if iTunes ever tries to write to the path.

Backing up images on external hard drive and restoring to new internal driv

I recently purchased a new external hard drive and a new internal hard drive. Before installing the new internal drive, I backed up the old internal drive on the external drive. Then I installed the new internal drive to my Macbook Pro. However, when I tried to access and print my Aperture images on the new internal drive, I received an error message saying "versions with unavailable master images cannot be printed." I clicked on 'show referenced files," but couldn't determine how to recover my master images. I checked the forum and under "referenced files go offline after restore from a backup" it said to go to "File>manage referenced files" but nothing else. How can I recover my master images? Please help - I have nearly 6000 images that are lost without recovering the master images. And no, I was ultra stupid in not placing everything in a vault = but I'm relatively new to Mac OS and thought a backup would be sufficient. Thank!

The volume name of the new hard drive needs to be the same as the old hard drive - rename it if you have to - then they should be fine.
If you cannot seem to make this work then you will have to reconnect them with locate referenced files under the file menu. Select all the files that are disconnected before going into the dialog.

Mac Pro 2.66 internal drives in a Mac Pro 64bit i7?

Is it possible to just unmount my internal drives from my workhorse Mac Pro 2.66 Dual Core Intel Xeon tower and mount in my new 8C Xeon 2X2.4g 64bit tower?
Thanks in advance!

Thanks in advance!
It's not clear if your workhorse is an original, or at least early Mac Pro and you new Mac Pro is the 2010 version, but if so, be aware that the drive sleds the internal drives are in are not the same. I don't know what would happen if you tried that swap but I doubt it'd be good for the new Mac Pro.
The drive itself could be transferred from the old sled to the new sled and it would fit but, if the new Mac Pro is, indeed, a 2010, it won't boot because 10.6.4 is the minimum OS needed. You could, however, use it for Setup Assistant or Migration Assistant purposes.

I am migrating to a new iMac via TimeMachine back up. My iPhoto libraries are on external drive. I'd like to migrate only the internal hard drive data to the new internal Drive then just plug in iPhoto library drive. Is this going be a problem?

I am migrating to a new iMac via TimeMachine back up. My iPhoto libraries are on an external drive. Both drives are backed up on Time Machine. I'd like to migrate only the old internal hard drive data to the new internal Drive and then just plug in iPhoto library drive to the new iMac. This would save having to transfer several hundred GBs of data. Will this work using Set Up Assistant?

Your user account on the new Mac must have a different UID than on the old one. See the pink box in Problems after using Migration Assistant for an explanation.
You'll need to change the permissions on the iPhoto library on the external HD. Do a Get Info on it, click the padlock at the bottom of the Sharing & Permissions section of the Info window and enter your Admin password.
Then click the plus sign, select the user account you want on the next screen, and click Select. Then change Read only to Read & Write for that user via the little arrows. Finally, click the "gear" icon and select Apply to enclosed items. That may take a few mintutes on a large library.

Can I use an internal drive or external only?

It seems you need a very large (1TB) drive dedicated to Time Machine.
As internal storage is always cheaper, would an internal non-boot drive in the additional PCI slot work for Time Machine, specifically will it see an internal drive or only external firewire drives?
And as I've read in other posts it's not recommended to partition the drive?
Any other formatting suggestions?
Thanks!

You have four drive bays in the computer. For best speed for backup you should install the backup drive in one of your four bays if possible. If that isn't possible then you have the option to use an external FireWire drive. You also have two additional internal SATA connectors. However, you only have one extra bay, the one for the second optical drive. You can install a drive in the spare optical drive bay and connect it to the same ribbon as the optical drive unless you have one of the models that uses all SATA drives, even the optical drive.
The general requirements for a TM drive are that it be partitioned using GUID and formatted Mac OS Extended, Journaled. A TM drive should be at least twice the capacity of the drive or drives it will back up. Over time a TM backup drive will fill up at which time it is either replaced or erased.

Time Machine won't back up to internal Drive through AFP?

Hi All!
Heres my Problem.
I have a Mac Pro system with 4 Hard Drives installed inside the internal Bays. I wish to use one for Time Machine for the Clients.
On the clients i get the error about it not having the correct AFP version. (I know this is a common problem within Lion).
Although surely if the hard drive is inside a Mac Pro Server running Lion then the client should be able to back up through it to its INTERNAL drive.
Or does this still count as NAS?
Thoughts?
Dan

We are going to need more information from you in order to help.
What kind of hard drive is this?
How is it formatted?
Where is it connected? Directly to your Mac?
How is it connected? USB? Firewire?
What have you tried so far?
What error messages have you received?

I'm seeing the "No" sign on Startup, and my internal drive doesn't show up.

Good day to you all. It's my first post here and I come to you in desperation.
Last night, i was browsing the internet and syncing my iPhone. Suddenly my iMac froze and there's no way to restart it but to press the back button. Upon restarting, it showed me the Apple logo then a few minutes more it showed me a "No" sign (ie. No Parking circle.) Noticing that this is a serious one, I pulled out my Snow Leopard installation disc and restarted the system. Last night, I managed to see the internal disk listed in Disk Utility, but it's in red. The partitions (Mac OS X and Windows XP via Boot Camp) can be seen but cannot be accessed. Desperate and tired, I slept the night off.
This morning, I tried my luck again. Fired up the iMac with SL inserted, opened up DU, and my internal drive is not in red anymore. I managed to open my Mac but I really noticed the sluggish performance. A couple of hangs later, I had to restart again using the button at the back, and there it was again: No sign. But now it's even worse. I can no longer see my internal drive in DU. Tried almost everything: resetting the PRAM (holding the X button) and pressing the C with SL disc inserted just doesn't cut it. The odd thing though, is when I press the Option key upon startup, I can see all the partitions (Mac OS X, Windows XP, Snow Leopard disc.) But upon clicking Mac OS X always ended up with the "No" sign.
I'm really desperate since I although I'm using Time Machine, I know I exempted some folders in there. Can you suggest some more instructions to make my internal drive show up? Is there a Terminal command of such kind for it? I hope my drive is still okay since I can still see all of the partitions via Option.
Any help is appreciated. Thank you so much in advance!

kaloyster,
Welcome to Apple Discussions.
From what you are describing it looks like your HD has either fully failed or is failing. I would suggest taking it in for service. The good news is you have been using Time Machine so you have a backup of most of your system. As you may know TM does not backup any MS Windows data.
If your machine is still covered by warranty or AppleCare this should be pretty painless. If you are not covered by either then just contact an Apple Authorized Service Provider and bring it in. The contact information in your country is:

Move Users folders from external drive to a new internal drive

Hi All,
I have a white Intel iMac running Snow Leopard. I have kept the Users folder (4 users) on an external hard disk (too many photos and movies). The internal hard disk recently died, but since all user data was on the external, I wasn't too worried.
The iMac now has a new hard disk, and I've installed the system back, starting from the original System Install DVD so that all the iApps are also reinstalled.
What I want to do now is to move the user folders to the internal drive, and use the external for backups. It seems that I can't use Migration Assistant because it only works when moving data from another Mac or another startup drive. I've looked around the forums and on the web, and the only thing I found was a post on TUAW in which the writer talked about eventually having to do this but without giving much info about how to do it (http://www.tuaw.com/2009/05/14/tuaw-tip-moving-your-home-folder-to-another-disk- or-moving-it).
Does anyone have any experience moving the user folders from an external drive to an internal drive, (or even just having a Mac recognize user folders on an external drive from another machine)?

Thanks, but that site doesn't have a clear answer.
Correct. As it clearly states, there are too many variables to have detailed solutions for every possible situation.
In the 'pink' box, which best matches my situation, the instructions begin with: "•You must be logged on to the account being moved...".
That's not clear at all. How do I log in to an account that doesn't exist yet? Connecting a hard disk that has a home folder to a new Mac doesn't allow me to 'log on' to that home folder's account, because it doesn't yet exist on the new Mac.
You may have to set up user accounts "from scratch." Then change the ownership and permissions on the old home folders so you can copy the contents of the sub-folders from the old home folders to the new ones.
If you're comfortable with permissions and Terminal, this may help: http://reviews.cnet.com/8301-13727_7-20013630-263.html

How to switch my Itunes library from External Drive to Internal drive

I recently formated my hard drive and backed up all my tunes to an external drive. When the computer was back and running I imported my tunes from the external drive to my Itunes. However itunes still reads music from the external even though the music is also in a Itunes folder in my Music folder in documents. I tried deleting Itunes and reinstalling but it still looks at the external first. When I look at the advanced tab in itunes it says the music plays from my C drive but if I disconnnect my external drive the music won't play because it's still looking there. I would like the music to play from my internal drive and only use my external drive for backing up. What should I do? Thanks!

Choose Home from the Finder's Go menu, double-click the Music item, and drag it there.

Problem with internal drive or a s/w bug that can be swatted?

Dear ones,
Recently I was greeted with a "persistent grey screen" upon startup. A restore using TimeMachine was unavailable according to Disk Utility. I ran an Extended Hardware Test. No problem indicated.
<rant>Two years of slow response and waiting for TimeMachine backups—what a waste of time—I bought a separate disk just for TimeMachine—what a waste of money. </rant>
I ran Disk Utility Permissions Repair from the SL install disk.
I ran Disk Utility Repair Disk from the SL install disk.
The error messages were:
"Unused node is not erased."
"Node = 192"
"Invalid key length"
I made a quick back-up using Disk Utilities—Restore to a newly-formatted disk which failed.
My internal 120GB "disk could not be validated."
I made a CCClone and a SuperDupe as best I could on a freshly formatted and partitioned outboard drive.
I formatted a second outboard fw800 hard drive and Installed SL on it, updated it and used Migration Assistant to move the files to the fresh boot disk.
Just before the migration finished, the screen turned dark grey and a multi-language alert appeared in white letters "You need to restart your computer. Hold down the power button until it turns off, then press the power button again." This has happened a few times on my wife's computer but this was a first for me.
I redid everything.
I ran Disk Utilities on the fresh drive and got a repeat of the original error message on my internal drive when I tried to repair the disk.
"Unused node is not erased."
"Node = 192"
"Invalid key length."
It seems as though the problem has migrated to the second boot drive.
Running Disk Utility returns the message, "Disk Utility Can't Repair The Disk…" for either the clone copy or the dupe copy.
I have followed all the steps in the order suggested in the link http://support.apple.com/kb/TS2570 without success.
I don't know whether to get a copy of something like Disk Genius, Drive Warrior, or a new drive. They're all about the same price.
Anyone got any ideas about saving anything?
My home drive can't be validated.

That's not normal. It indicates you've been having some sort of problem for two years.
I ran Disk Utility Permissions Repair from the SL install disk.
You should run that from the OSX volume. See [About Disk Utility's Repair Disk Permissions feature|http://support.apple.com/kb/HT1452].
A restore using TimeMachine was unavailable according to Disk Utility.
Huh? You don't restore from Time Machine backups via Disk Utility.
"Unused node is not erased."
"Node = 192"
"Invalid key length"
The file system is corrupted. It's possible a heavy-duty 3rd-party +Disk Repair+ app, such as Disk Warrior, can repair it. They're not cheap, though. DW is about $100.
I made a quick back-up using Disk Utilities—Restore to a newly-formatted disk which failed.
My internal 120GB "disk could not be validated."
Probably because that type of backup copies the corruption.
Try a full system restore from your TM backups, per #14 in [Time Machine - Frequently Asked Questions|http://web.me.com/pondini/Time_Machine/FAQ.html] (or use the link in *User Tips* at the top of the +Time Machine+ forum).
But in step (c) there, take the time to reformat your internal HD. It will only take a moment.
Since you've apparently had this problem for a while, it's possible it will restore, but not start up. If so, just install a fresh copy of OSX from your SL install disc. That won't affect anything else.

Can I use an external hard drive on my iMac if the internal drive is dead?

The internal 1 TB hard drive on my 2009 w/Mavericks hard drive is failing. I clone that drive to an external hard drive as a backup and often boot from the external when I want to do some maintence (Disk Warrior) on the iMac drive. So far Disk Warrior has saved that iMac drive but eventually it won't be able to do so.
I looked into buying a new internal drive and replacing the old iMac drive but the procedures are not as easy as I hoped. So my question becomes: if/when that internal drive goes belly up will I be able to set the external drive as the main drive through System Preferences and automatically boot into it each time I need the machine? Or would I have to boot into a USB Maintenance drive then reset to reboot into the external drive each time I wanted to use the machine.
Of course I'll be looking into buying a new iMac but until then I want to use this older machine as much as possible.
Thanks.

Yes, you’ll be able to do that.

How do I move ITunes Library to External with only 5GB of space on Internal Drive without getting Space issue message when Consolidate library option is executed?

Details:
250 GB Internal Hard Drive
50 GB iTunes Library
1 TB External Drive w/ 153 GB of Open Space that is Partioned
Steps followed:
http://support.apple.com/kb/ht1449
I get Stuck on Step 11 Consolidate Files to new external drive location with Error message: Not enough space to move files.
This makes no sense Apple. The purpose in doing this is to free up space on my internal drive?
Any help would be much appreciated as I'm stuck and can't seem to resolve or find any suggestions to resolve...

Don't use that method. It does move the whole library, it just moves the media. The whole library is best left intact.
iTunes: How to move [or copy] your music to a new computer [or another drive] - http://support.apple.com/kb/HT4527
Quick answer if you use iTunes' default preferences settings: Copy the entire iTunes folder (and in doing so all its subfolders and files) intact to the other drive. Open iTunes and immediately hold down the Option (alt) key (shift on Windows), then guide it to the new location of the library.

How can I "archive" mails in Mail App to another internal drive/partition to save space but still have it searchable in spotlight (and preferably visible, searchable, draggable in Mail App)?

How can I "archive" mails in Mail App to another internal drive/partition to save space but still have it searchable in spotlight (and preferably visible, searchable, draggable in Mail App)?
Background:
I am using Mountain Lion and Mail App and running out of space on my small primary SSD drive (where I keep OS, apps, key user preferences/data and mail for speed). The mail data is the big variable (many GBs) and I want to "archive"/move some of the old mail to my 2nd drive inside the Mac. But I still want it searchable inside spotlight and preferably even inside Mail too. And I'd like to be able to still drag and drop old mails into this archive folder.
What I've tried that seems to work:
This seemed to work:
1. Move the archive folder/mailbox to the 2nd drive/partition/folder (don't delete anything inside Mail App)
2. Create a symbolic link from its new location to the original/old location
This seems to work, it looks as "normal" and as if nothing happened inside Mail App but the folder now resides elsewhere and seems searchable etc. But I'm not sure that once caches refresh or over time with updates etc if stuff will break horribly or corrupt.
Is that the right way to "archive" mails in Mail App to another internal drive/partition to save space but still have it searchable in spotlight and visible, searchable, draggable in Mail App?
Thanks in advance!
Cheers,
Daniel

I'm having a similar but slightly different problem. My company just migrated to Gmail, and it's saving mail drafts every 30 seconds into my Trash folder.
I unchecked the "Show in IMAP" preference in the Gmail settings, but my Drafts folder completely disappeared. I went back and checked it and the folder reappeared (with my drafts still in there).
I like the idea if starting an email on my laptop and having the option of finishing it on my iPhone or iPad, so only saving Drafts locally would not be ideal.
