Saved presentation is smaller on my internal drive than on my external disk

This is not a big deal and it does not affect the use or effectiveness of Keynote, but I am curious. If I save a presentation on my internal drive it has a smaller file size than if I move it to my external disk. Can someone tell me why?
Thank you
Mireille

Different disks and disk formats have different allocation block sizes; except for zero-byte files, each file needs to occupy at least one block. For this reason, some space is wasted on a disk, and the larger the disk is, the more space will be lost. Using the Mac OS Standard format for a disk causes much more space to be lost compared to Mac OS Extended.
When a package is placed on a drive, each item in the package counts as a separate file. Creating a disk image with the Disk Utility in the /Applications/Utilities/ folder and storing files on it will reduce the amount of lost space.

Hi i use a macpro i7 wt 7200rpm internal drive i get this message Disk is too slow-(prepare) (-10001) when i am using logic 9

Hi i use a macbook pro 17" 2.66ghz intel core i7 with 8gb ram & a 500gb@7200rpm internal drive i get this message "Disk is too slow. (Prepare) (-10001) when i am using logic 9 wiyh just a 5 vsts loaded 2 of them being esx24's . i used to not get this warning earlier in the same or even heavily loaded projects.
When i press play the beachball appears for a minute or so then the message.
Even when i open up a new project a beachball appears for about 30-40 secs and then the project opens up
i have even tried opening up the projects w/o any vst's loaded (i have disabled them from audio units manager)
Initially i thought it was a hard drive problem so apple had it replaced for me but i am still encountering the same problem.
have even tried disabling the sudden motion sensor from terminal no luck there too
tried reloading osx 10.6.7 no luck there too
what do i do

How full is your 500 GB hard disk?
Do you have 10% to 15% free space available?

Macbook 2012 not booting from internal drive but booting from external usb drive

hi everyone!!
here is what happened:
i have worked all day on my macbook pro, normally. when i got home and turned it on (i always power it off for rolling with it) it just didn't load the OS.
i run mavericks on a i7 mid 2012 macbook pro 13". it had an accident on last december and fell on the ground, but i've changed the hdd and it worked normally until last week when this happened.
i have a copy of my system on a usb drive and tried to start up from it and it worked.
i took my hdd from inside the lap top and started from it (yes, the same hard disk that was inside the machine) and it worked.
i took the macbook to an apple store and the "apple genius" that was there started up my machine from inside with another hdd running yosemite that they have in the store for testing.
today i bought a new hdd and put it in. but i can't format it or install the system. i had these 2 errors on disk utility
"partition failed with the error: wiping volume data to prevent future accidental probing failed"
and
"restore failure an error (32) occurred while copying. (broken pipe)
so:
it loads from my internal drive, but only when its connected via usb
it loaded the apple store drive internally
it does not format my new drive nor install the system on it
ANY suggestions, please??? it's really difficult to me to solve this problem...
thanks a lot!!!

Must be a bad SATA cable undetected by Apple Techs. A result of the drop but they are also quite fragile.
Disturbing the cable can cause it to work for a while. Cheap repair at iFixIt.

Internal Drive Performs Strangely in Target Disk Mode

I am trying to use one of my internal HDs on my MacPro Mac Pro (2x3 GHz Quad-Core Intel Xeon) as a destination for a HD clone using SuperDuper.
I startup my MacPro in Target Disk mode using FW800 cable and 2 of my internal HDs show up instantly. My 3rd internal HD shows up after maybe 3 minutes for some reason. When I select it as a destination using SuperDuper, the files just don't want to copy at an acceptable speed and the app eventually errors out. Why would one internal HD not work in Target Disk mode when the 2 others do? The HD works fine when I access it from my MacPro and DIsk Utility returns no errors on the drive.
Here is the internal HD info:

Hi, problem solved! Thanks very much for the help. As soon as I opened up the G4 I remembered what the back of the hard drives looked like and after quickly changing the jumper blocks and hooking the computer back up everything worked as you said it would. Again, thanks! I am curious, though, is there no way to have both drives show up while in Firewire mode. It's no big deal, the migration assistant seems to have worked flawlessly but it might be handy to have both drives show later if it's possible.

SSD Internal Drive Showing Up As External Drive!

Hello,
My Internal SSD is showing up as an external drive. I did a backup of all the data to another drive, erased it and re-partitioned it but it is still showing as a removable external drive. I don't know what to do as it "was" my startup drive so in the meantime I installed OSX on another drive for now. Would there possibly be a terminal command to change the drive to internal or something else I can do?
I appreciate the help.
Here are some pics to help hopefully.

As LexSchellings said, anything not on the built-in internal bus is considered external by the OS.
By the way, don't look at your device using System Information because that will really set your head spinning:

TM tries to backup to internal drive instead of nominal external HD

This is a odd behavior since I restored to the default settings (backup every 1h instead of every 3d before). As its now not unusual that the external HD maybe offline TM tries a backup on the internal HD instead! However it never finishes but stops with a "failed backup" notice and an empty "Backups.backupdb" Folder on my internal HD.
Anyone seen this before? Thanks, Emilia

These folders are created at root level of the internal HD thus at "/".
It happened after I told the Utility "TimeMachineEditor" to restore to the default values.
I can see from the logs:
Jun 16 09:41:10 dhcp-131-XXX-XXX-101 /System/Library/CoreServices/backupd[460]: Backing up to: /Backups.backupdb
Jun 16 09:41:10 dhcp-131-XXX-XXX-101 /System/Library/CoreServices/backupd[460]: Nothing to backup.
that the backup is tried while I am on the road with Airport LAN instead of the office Ethernet cable. However I never defined a network drive or similar for TM.
thanks, emilia

My internal drive keeps ejecting - why?

I have 4 bays on my Mac Pro and each one contains a drive: the HD on which is the OS (ML- at this time) and three scratch drives for media.
The largest of these drives is a 3TB one. Every morning I wake up my MacPro and see the message that my 3TB drive was not ejected properly and that the OS will try and do it's magic next time it is connected. As stated, this is an internal drive and not an external one via thunderbolt or FW or USB.
Is this common? I have important media on this drive for a client and cannot be restarting my MacPro every morning.
Regards,

That error is indicative of a serious problem with the drive. The logs may indicate that it has suffered an I/O Error.
You need to back up anything that has not already been backed up right away -- it may already be lost. Most drives never recover from this.
Do not delay in buying a replacement drive -- you WILL need it.
At a minimum, you should attempt to Erase the drive and write Zeroes to every block. But I do not hold out any hopes for it ever working properly again. Drives that do this may be good for nothing but a doorstop.
Many users find that using a small fast Boot Drive -- containing nothing but System, Library, Applications, and the hidden Unix files including Paging/Swap -- gives them a slight overall Performance boost. User files are moved off to other drives to keep the System's incessant "snacking" from the Boot drive from slowing down the other drives.

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 do you boot from an external drive when internal drive is dead?

The internal drive is dead, but I have a complete dupolicate on my fire-wire external drive. I think I remember reading that there is a combination of keys to press down when starting to allow one to choose which drive to use as a startup volume. As it is, the thing won't start up at all.
So I know it's supposed to run from the external drive, but how do you get it to boot from it without having designated it as the startup when it was last running?

Hold down the Option key when booting the computer.
When I asked the question I was working on my daughter's ibook.
Now I'm back home and I have a firewall external drive, so I tried pressing option when I started and icons for startup drive come up BUT there is only one icon -- that being for my internal drive. I know that the external drive, which has a duplicate of the internal, is capable of starting it up ok, because when I go ahead and , after starting it up on the internal drive, then pick the external drive to start and then restart it, it goes to the external drive ok. But again, if it has been preferrenced to start on the internal drive and I do the thing by pressing with option when I start, it doesn't give me the option to use the external drive. (The external drive is partioned, and the duplicate startup is in one of the volumes, but I don't think this should have anything to do with anything, since it can start up using the appropriate external hard drive volume when I have selected it in my preferences.)

Internal Drive does not mount

yesterday on a MacBook mark l;
after a very long MSN typed session, MSN wouldn't close and after a while I turned off MBook turning power off with long press on on/off key.
now...
Flashing suitcase with ? mark flashing at start up
I tried all the tricks under the sun ,
Pram (failed),
start with Option Key (failed),
start with X key (failed),
soft boot (failed),
single user boot (failed),
Disk Utility from install CD does see the drive but "Repair" tab is greyed out.
No SMART status displayed,
tied to use Terminal from the install CD (failed)
booting from external clone Drive via Firewire = which would not even see that internal Drive so couldn't use Disk Utility from that system either ;
tried AppleCareProtectionPlan CD - TechToolDeluxe (wouldn't mount),
what can I possibly do ? I do not have DiskWarrior.
any chances to have that internal Drive "seen" by some magic device which would at least check it and repair it so that I could erase it and apply a recent clone of it I did with SuperDuper.
many thanks enjoy your weekend

Sorry, I seem to be a bit over your head, but worry not, I'm frequently over my own head!
a bit terrified to do something wrong
Completely understandable, I'll try to be clearer.
you say :Can you Safe boot off the external and try it again?
so I need to "Restart" my set up - then engage the SoftBoot mode while Clone's ED boots
then what do I do ?
I think I misunderstood, forget all that please.
as DU off the Clone does not "see" the MacBook Drive - neither "Activity Monitor" (Disk Usage tab) when it normally see it.
my Clone is 2 month old hence why I desperately need to access some data if I can
OK, we need a whole other tact here. If you have twice as much free space on the external, then you won;t need another external drive, ut what I recommend here, (Laptop drives are very short lived, btw), is to get these...
If DiskWarrior can't fix it, you might try Data Rescue II...
http://www.alsoft.com/DiskWarrior/
http://www.prosofteng.com/products/data_rescue.php
(Has a Free Demo to see if it could or not, but you'll need another drive to recover to).
Or FileSalvage...

I cloned my internal drive to a larger drive... bootcamp issues...

MacBookPro unibody 2.66... 10.5.8
i want to swap a larger drive into my laptop... old 320g for a 7200rpm 500g...
i cloned my internal drive to the larger externally enclosed drive... it took 4.5 hours with copycatx...
before i physically swap the two drives, i want to be sure i can do the following...
i'll need to use the new available free space (167g...) for at least one new mac partition to run as a separate boot-up...
i understand there are issues with bootcamp when either resizing or partitioning....
i took a look with disk utility to see the free space and perhaps format that space for the other mac bootup... i saw a warning that bootcamp might get affected...
i then took a look with drive genius.... when i looked at the repartitioning page, i saw no warning...
i formatted the free space as journaled hfs+...
when i attempt to run "vmware fusion" to launch the windows partition i get an error of the partition not meeting it's original specs... something like that... i tried a few things from within "vmware fusion"... reassigning the windows partition... importing... nothing doing...!
my question is for someone who has specifically done a cloning of a dual boot disk drive onto a larger drive, swapped out the drives and has successfully commandeered the remaining free space as a new mac partition...
seems like something that should be easy enuff to do....?
but perhaps it needs a more exact path for success...
help....?
thank you...

Hi M,
a later done partitioning to add additional partitions to a harddisk alters the position of the BootCamp partition in the partition table so that the Windows Bootloader can not 'find' the Windows partition.
With Windows XP it helped to simply edit the Boot.Ini file and point it to the WIndows partition.
With Vista and Windows 7 there no longer is a boot.ini but EasyBCD http://neosmart.net/dl.php?id=1 can do the same.
One thing to remember though is, that even Vista and Windows 7 'suffer' from the limitation of four partitions on one harddisk immenent to the Master Boot Record (MBR) since Apple EFI/GPT/MBR emulation can not handle Extended Partitions and Logical Partitions inside an Extended Partition.

Another tip for working around iDVD encoding errors: Use internal drive

I've had several projects that produced the encoding error while rendering the menus, I've also seen a number of tips in this discussion area, e.g., have 20 GB of free space, delete iDVD preferences, delete encoded assets, and make sure your chapter markers are not near a transition or end of a clip (good luck with that using iDVD to set your chapters). Neither of these tips alone allowed me to burn a disk image to disk, but I'm confident they contribute to a more stable iDVD performance overall.
In my case, the only way I've managed to make the projects to work is to copy the iMovie project over to my internal drive, create the iDVD project on the internal drive and to save the disk image to the internal drive.
If you're low on internal disk space, as I am, easy to move assets is another advantage of using iMovie 6 over iMovie 8, i.e., you can create the iMovie project on the external drive and then drag a temporary copy over to the internal drive, then you can launch iDVD from within iMovie 6 without the annoying step of exporting to the Media Browser. When you're done, delete the temporary movie to free up space for your next project. The iDVD projects can also be moved to a backup drive or deleted.

You'll always get better results on the startup volume / internal HD (as opposed to an ext. HD) provided you also have at least 20GB's of available HD space remaining. Anything less is often problematic at best.
My suggestion in this situation is to find a way to clear more HD space. You can clear video files already burned to DVD-R media, burn your iPhoto Library to DVD to clear more space , or even consider clearing languages you won't need on your system with an app like Monolingual. No problems will be created by removing unneeded language files (however it's highly recommend you avoid removing architectures on any intel mac).

How small can I make the boot camp partition on my MacBookPro internal drive?

it seems that in order to get Windows7 on to my old non supported MacPro 1.1 that I need to firist install onto this mid 2009 MacBook Pro I want to do the install onto an external firwire800 hard drive which I have formater and Downloaded and installed the Windows support folder using the boot camp installer but the installer wants to grab 20 gig of my internal drive for the win 7 install what is the minimun that I must have on the internal drive to install and use win 7 on the external drive?
is ther annother way to get Win7 onto my MacPro1.1 where it can live on an internal drive of its own. I do not have have it running on this MBP5.3 other than to get it running (64 mode) on the old tower In addition to the MBP I have at hand the esternal drive a blank 16 gig thumb drive and a firewire800 external DVD drive that I use mostly as a burner on the macpro as it is faster than the internal superdrive that it came with

I assume that is a product so then I can remove the bootcamp partition from my internal drive and boot to the firewire 800 drive or do I need to have a SSD drive inside the macbookpro first?

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.

Anyone using a 1TB internal drive on a MacBook Pro?

Hi. I plan to upgrade the internal drive (250GB) on my MBP to either 750GB or 1TB. OWC sells a 1TB drive from Western Digital. Does anyone have experience with this drive? Thx
http://eshop.macsales.com/item/Western%20Digital/WD10TPVT/

Yes, I have this drive installed in my 2010 17". Fits fine. I have heard that it also fits in the 15". A couple of things:
The drive is only 5200 rpm, so expect startup to be a tad slower. Not awful, just a little slower. I never really restart my Mac so this is only an issue every once in a while - mostly during system updates.
This drive has anti-drop/shock protection built-in, unlike the Apple drives. To avoid any issues, I disabled the built-in protection. A quick google will tell you how to do this. It is a couple of lines entered into the terminal. The setting is remembered after the lines are entered.
The one annoying bit that took a little while to figure out was the drive was making *a lot* of noise due to excessive head parking. It is set up out of the box to very aggressively conserve power. There is a solution to this and it is a small program called "hdapm" it is a little command line tool that sets the driver to a less agressive power saving mode at startup. There are also instructions online for this. google "hdapm" for details. You need to download the binary, stick it in a folder, then set up a very small startup script to point to it. All done.
The drive is excellent and huge. Very quiet after the head parking issue was solved. I've been running mine for about 2 months or so now. Highly recommended.
