Format: Mac OS Extended

Hi. I'm new to iTunes and have started burning CDs. I'm burning as Audio CD because I want them to be universally playable on any CD player. But when I check the file under Get Info, Kind:= Volume, Format:= Mac OS Extended. What is this format and will it be universally recognized?
Also, how do I know the burn is good? When I try to play the CD to check it, the file launches from iTunes. The only alternative was to trash the iTunes file and then play the CD. Is there a better way?
I am copying these spoken word files from CDs which are labelled AIFF. The import setting has been at AAC Encoder which doesn't seem to cause problems, but should I be importing under AIFF Encoder? Does it matter?
I am sending these CDs out by mail and may never know if the lectures can be heard on a regular player. Do I risk a bad copy by using the default Max. Speed and will I be informed of failure? I am planning to make multiple copies of each original CD I have and want some way to verify they are good before mailing them. I've searched Help, etc., but these basic questions don't seem to be addressed. Thanks, Alex.

No relation, except that we share the same first name.
As Mac OS Extended is not listed as a format choice here, does this result from choosing as a 'Data CD or DVD' ?
That is correct. The format of a 'real' Audio-CD will be recognized by the Finder as
b Audio CD
Also, does it sound right that these AIFF CDs that I import as AAC and then burn, end up being about one tenth the file size
Whit the default settings of iTunes that is about true for
b importing only.
Lower bitrates means smaller files and lesser audio quality, higher bitrates means larger files and better audio quality.
Is the compression that great with AAC? If so then I assume I could put 8 or 10 lectures on an Audio CD.
Unfortunately not. When iTunes (or another burning program) burns an
b Audio CD
, all files, wether they are MP3 or AAC or...., are converted to AIFF.
That means that they're expanded to meet the specifications of an audio CD.
So, time is the limiting factor, not file sizes.
The only way to fit more 'time' on a CD is, to burn it as MP3 CD.
And most regular players don't accept those.
Could this high factor of compression ~10:1, be a result of what the file info calls 'Profile: Low Complexity' -i.e. the software recognizes it is non-continuous data - simple speech as opposed to a symphony orchestra?
Speech is indeed of low complexity. The human ear can hear frequencies from about 20 to 20,000 Hz (dependent of the age). Children can even hear lower and higher freqs.
The sound of a symphony orchestra produces about all those frequencies and even lower an higher freqs.
That's pretty complex.
The 'reach' of a human voice fits the range from about 300 - 3,000 Hz, so that is indeed of low complexity.
Hope that answers your questions.

Btw. I'm not an audio expert, so I expect others to correct me if I'm wrong.

HT4589 How can I get my Mac laptop FCPX Events Library to see my external drives? Yes it is formatted Mac-OS-Extended (Journaled)

How can I get my Mac laptop FCPX Events Library to see my external drives? Yes it is formatted Mac-OS-Extended (Journaled).

I do not seem to have that as an option. Attached is a screen shot with the gear popup open. I simply copied the event and projct folders from my desktop so I could contiue working while on a trip with my laptop.

Hello. I keep my IPhoto library (about 90GB) on an external HD and am trying to back it up to another external drive. Both are formatted Mac OS Extended (Case-sensitive, Journaled). Recently, backup has failed from the start due to error 36. Howtoresolve?

Hello. I keep my iPhoto library (about 90GB) on an external HD and am trying to back it up to another external drive. Both are formatted Mac OS Extended (Case-sensitive, Journaled) and both check out when scanned with Disk Utility. Recently, backup has failed from the start due to error 36. Any ideas how to resolve? Also, what's the maximum recommended size for an iPhoto library file? Thx!

Since you can't drag the library to the other EHD for the backup see if you can duplicate it (if you have enough room on the drive) by selecting it and typing Command+d (duplicate).
If you do rebuild the library without a backup and it goes awry you won't lose your photos but you may lose your orgnaizational efforts. So try the following:
Fix #1
Launch iPhoto with the Command+Option keys held down and rebuild the library.
Select the options identified in the screenshot.
Fix #2
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 in the location of your choosing 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.
NOTE: Fix 2 above might be the method you might want to try first with iPLM creating the new library on your second EHD. If it works that would get your backup copy on the second EHD at the same time as repairing it. If it does'nt work then go back to Fix 1.

HT201250 Will Time Machine wipe my external hard drive if its formatted Mac OS Extended (Journaled)?

I want to use Time Machine to back up my mac. I have heard that it will wipe the HDD if its not formatted correctly. Disk utility says its
Mac OS Extended (Journaled). Is this alright? or will it wipe it?

Yes, if you use Disk Utility to reformat the drive or assign that drive to TimeMachine it will wipe all existing data off the drive/partition.
Like was mentioned, only use one drive for TimeMachine and preferably another one for a bootable clone.
Most commonly used backup methods

I've bought Mountain Lion but my iMac's HD isn't the correct format (Mac OS Extended(Journaled) instead of GUID partition what do I do?

Can I just back up to Time machine, then reformat disk then re down load?

As mende1 stated, the two are different and must be both.
If you open Disk Utility and select the hard drive (the type, size, and serial number), not the volume (Macintosh HD), it will tell you at the bottom of the screen what the Partition Table is. It should be GUID. If not, then you will need to back it up, then repartition the drive. Also, copy the Mountain Lion installer onto another drive so you don't have to download again. It is in the Applications folder.
There are a few methods to get back where you are, including wipe, install old OS, restore from TM, install ML.
You might search the web for a tutorial on creating a boot/install disk using the Mountain Lion installer.
Another easy way is to use something like Carbon Copy Cloner or SuperDuper to clone your current OS onto another drive. Then, boot using the external you cloned. Use Disk Utility to re-partition the internal drive as noted below, then Clone your current OS back to the internal. Then, use the installer you tucked away to reinstall.
If running Snow Leopard, you need to boot using your install disk, then open Disk Utility.
If running Lion, you need to boot into the Recovery HD by holding down cmd-r on restart.
From there, open Disk Utility, select the hard drive, then the Partition tab.
Select 1 partition from the partition layout dropdown (or however you'd like, just don't use current).
Set the Name of the disk. Macintosh HD is the norm, but you can name it anything you want.
Set the Format to Mac OS Extended (Journaled)
Click the Options Button.
Set the Partition Table to GUID Partition Table.
Back on the partition tab, click Apply.

Imovie not seeing partitioned time machine drive. I partitioned my TM 2GB and formatted Mac OS Extended (Journalled). These drives in iMovie have a Yellow exclamation mark and I cant access events. Can access in Finder?

Any assistance would be greatly appreciated

Thank you for your response. I was able to successfully format the drives Extended journaled when they were out of the raid configuration. I was not able to format as Extended (not journaled) in the Raid configuration.

Error code 0 even with disk formatted Mac OS Extended

Hi Guys
I always make "manual backups" (copy files and folders from iMac to External HD's) and this means overwriting existing files and folders on the external HD's all the time.
Now many files are bigger than 4GB but only when I select a large amount of folders and files at the same time, to paste them on the external HD's, I get the "error code 0"...
I reformatted the drives to Mac OS Journaled etc. but it didn't work
What to do know? This freaks me out!!
Many thanks
Bob

Hi Linc,
Hereby two screenshots:
1) I copy a folder from my desktop to my external hd which is formatted as mentioned above. When I overwrite the existing folder on the external HD, this is what shows up:
I click "bewaar nieuwere" (or "save new files" or sth translated in english ) and just a second later, this is what shows up:

How to format an external hard disk Mac Os Extended (Journaled)?

hello
I connect an external hard disk (2.5' IDE Western Digital Scorpio Blue, WD2500BEVE) via USB or FireWire to my Mac mini. The Disk Utility tool shows an external disk drive of 128 GB - but the disk has 250 GB. How can I format the external USB/Firewire-harddisk 250 GB "Mac OS Extended (Journaled)"?
I tried also to format the disk on a Windows PC (Windows XP). But I could not find a software to format "Mac OS Extended (Journaled)".
Any hints on this? Thanks in advance for any feedback!

As I use theses hard disks in a external hard disk case, I'm asking me whether my hard disk cases do not support more that 128 GB disk capacity. Is that realistic?
It is not only realistic but probably the reason your Mac cannot see more than 128 GB of the capacity of the drives mounted in them. It has nothing to do with the interface between the Mac & case (like Firewire) but instead with the controller in the case that connects the raw ATA drive to that interface. Older ATA standards used a 28 bit LBA (logical block address) scheme to access the disk. For 512 bytes per sector this works out to a maximum of 128 GB of addressable disk capacity. The ATA-6 standard, also called Ultra-ATA/100 or just ATA-100, increased the bits in the address space from 28 to 48, with a disk capacity limit of 2 petabytes.
ATA-6 was introduced in 2001, so any external drive case made before then for ATA drives will be forever limited to 128 G. Even now, some come with a controller that does not support the ATA-6 standard, & essentially none have all the hardware to support its full 48 bits of address capacity. However, since 2 PB (2000 terabyte) drives won't be available anytime soon, all you really need is a case that is ATA-6 or better compliant & supports enough address bits for the largest drive you intend ever to put in it.
Case makers don't usually make this information easily available but many now include a "bullet" spec about the maximum capacity their case supports, typically rounded off to simple numbers like 320 GB, 500 GB, or whatever. If you can't find this info, you can assume that the newer the case the more likely it is to support larger capacity drives, or just buy one with a good return policy & test it yourself with the largest raw drive you own.

Using TM with Drobo on Airport Extr - what format? HFS+ or Mac OS Extended?

I have a Drobo that I used to connect directly to my iMac, which was in HFS+ format. I've recently purchased an Airport Extreme, to which I want to attach my Drobo so it can be used as a shared USB drive for all my other Macs. When I redirect Time Machine to the Drobo that is now attached to the Airport Extreme, an error pops up that says, "The backup volume is not in Mac OS Extended (Journaled) format, which is required."
Do I need to reformat my Drobo to Mac OS Extended or is there some workaround? What should I do?
Thanks!

Any other thoughts out there? Pondini? You seem like one of the resident experts.
That's a bit overstated, I'm afraid. I've never used a Drobo (directly attached or not) or any network drive with TM. About all I can say is, some folks with directly-attached Drobos seem to get it to work well, others don't. Some of the network hardware/software seems to work sometimes, sometimes not. Many that had worked fine in Leopard no longer work in Snow Leopard, apparently because of some changes or new features Apple started using that aren't supported by all NAS devices.
One thing to keep in mind is, although they never say it explicitly, Apple designed TM with novice to intermediate users in mind. Folks who've never used any sort of backup app at all, and won't unless it's very simple and easy. Thus the automatic deletion of the oldest backups, for example, so users don't have to manage the space themselves. While it will work in some fairly heavy-duty and complex situations, it's just not designed as an "enterprise class" app.
I'm pretty thoroughly confused right now, so I'm basically trying to figure out what the best options are for me. I have 3 computers (two with Snow Leopard, one with Leopard), one Airport Extreme, one Drobo, and of course Time Machine. Should/can I use my Drobo (dechamp suggests that the NetGear product is worth looking at)? If so, should I connect it to one computer to share or get a Droboshare device to share via ethernet (I've already eliminated the possibility of attaching my Drobo to the Airport Extreme)?
Since you've already got it, I'd be inclined to try it connected to the iMac; back the iMac up to it directly, and the others via sharing. In that case, partition it if you can (I've heard Drobos can't be partitioned), so at least the iMac has it's own, exclusive space (see #4 in the Frequently Asked Questions *User Tip* at the top of this forum). If you can partition it, you may or may not want to make separate partitions for the drives being backed-up separately.
#4 in the FAQ Tip applies mostly to Macs being backed-up directly; for backups in a sparse bundle, you can simply delete the sparse bundle if you have or want to delete all of them.
Or try it attached to the Airport. If it works, it works, at least for now.
Also, I understand from previous posts that when TM accesses a network device it creates a sparsebundle instead of the regular backupd
Correct. The Backups.backupdb folder is inside the sparse bundle, which doesn't sound like a big difference, but it is. The sparse bundle has it's own *Partition Map Scheme* (APM) and Format (Mac OS Extended (Case-sensitive, journaled)) which you can't change.
- is that an issue at all? (I originally had my Drobo attached to one computer and am now sharing it from another computer - does that mean that the backupd files from the previous computer are now useless and can be erased since TM created sparsebundle once I started sharing that drive over the network from another computer?)
They're not useless, as you can still access and restore from them via the +*Browse ...+* option (see #17 in the FAQ Tip), but the old and new sets are completely separate. Also, TM won't delete the oldest of the old ones when it needs room for new backups. You get to do that yourself, either by deleting the Backups.backupdb folder (emptying the trash will take a very long time), or one-by one via TM (see #12 in the FAQ Tip).

Which MAC OS EXTENDED format? journaled, case-sensitive?

I'm going to be using my new Mac Pro for editing corporate videos and I want to use an external firewire800 LaCie 1tb drive from my windows computer on my Mac.
I've gone to the disc utility screen and not sure which format I should re-format it as. I've been told to use MAC OS EXTENDED but there is several flavours: journaled, case-sensitive, etc.
I need it to be as fast as possible but also reliable and able to handle large video files (e.g. 60gb HD files.

The Mac can read and write FAT32 and FAT16 volumes, and it can read NTFS volumes (cannot write to NTFS). FAT32 will only allow files up to 4 GB in size, so it's really not acceptable for video. The Mac generally reads it's own format, Mac OS Extended faster and more reliably.
If you need platform independence, you have a few options.
1 - Get Windows machines to read Mac OS Extended with special software.
2 - Get the Mac to write to NTFS with special software
Because of the way the Mac manages external hard drives, option #1 is ideal. But you should keep in mind, the Mac will run your FireWire 800 drive faster than the Windows machine not because of compatibility, but due to the fact that Windows doesn't support FireWire 800 and limits transmission with those devices to FireWire 400 speeds (or so I've been told).
The Mac Pro will partition using the GUID Partition Table scheme by default. This partition scheme is required to boot an Intel Mac, but not for simple reading and writing of data. I'm not sure what implications this might have on the ability of your Windows system to read the data, but it's worth checking. It's possible that the Windows software might not recognize GUID, but I'm not sure.
I think most people who edit video professionally on the Mac are choosing to alleviate this confusion by avoiding Windows altogether. That works very well.
Use Mac OS Extended (Journaled).
Case-sensitive can sometimes cause problems and is best avoided.
Interesting to note, Adobe software won't run on a case-sensitive volume.

Reformat to FAT32 from Mac OS Extended

Bought iomega 320GB HDD formatted Mac OS Extended from Mac Store and was told to reformat to FAT32 simply go to Disk Utilities/Erase/Volume Format/FAT32 and voila!. Problem is, under Volume Format there is no FAT32 only Mac OS Extended (Journaled), Extended, Case Sensitive-Journaled and Case sensitive. Same on both my iMac and Pro and both running 10.5.5. I need to be able to transfer files (movies, photos, data) from my Mac and be able to read them on a PC running Vista overseas.

I had the same problem. But when I select MS-DOS (FAT) and erase the external hard drive, the format is still in Mac OS Journaled and then the sub drive is in MS-DOS (FAT). However, my XP PC still does not recognize the drive. How can I make it just MS-DOS (FAT)?

Mac OS extended journaled drive cannot be written to

I have two WD MyBook external drives that are formatted Mac OS extended journaled. Permissions are set for owner to write to the drive. I am the owner. Carbon Copy Cloner and Time Machine write to the drives regularly. When I attempt to copy a file to the drive a small window opens telling me "The item is not writeable. You do not have sufficient permissions to write to the item."
Any help in understand what's going on here would be greatly appreciated.

Try trash the com.apple.iPhoto.plist file from the HD/Users/ Your Name / library / preferences folder.
(On 10.7 or later: Hold the option (or alt) key while clicking on the Go menu in Finder to access the User Library)
(Remember you'll need to reset your User options afterwards. These include minor settings like the window colour and so on. Note: If you've moved your library you'll need to point iPhoto at it again.)
What's the plist file?
For new users: Every application on your Mac has an accompanying plist file. It records certain User choices. For instance, in your favourite Word Processor it remembers your choice of Default Font, on your Web Browser is remembers things like your choice of Home Page. It even recalls what windows you had open last if your app allows you to pick up from where you left off last. The iPhoto plist file remembers things like the location of the Library, your choice of background colour, whether you are running a Referenced or Managed Library, what preferences you have for autosplitting events and so on. Trashing the plist file forces the app to generate a new one on the next launch, and this restores things to the Factory Defaults. Hence, if you've changed any of these things you'll need to reset them. If you haven't, then no bother. Trashing the plist file is Mac troubleshooting 101.
Then try select it again.

Lion Install thinks that the system disk "Macintosh HD" is not Mac OS Extended (journaled); it is. Exactly what do I do in Disk Utility to "reformat" the disk, I don't see that listed on the menus.

Error Message, during installation of Lion; “This disk is not formatted as Mac OS Extended (journaled). Use Disk Utility to enable journaling or reformat the disk.” The disk I selected to install OS X on, was the only one listed, “Macintosh HD”. The results of a Disk Utility check are; Format: Mac OS Extended (journaled), Name: Macintosh HD. There is a fresh Time Machine backup. The computer was Restarted and installation attempted again - same result. I have downloaded Lion a second time, and tired install again, same results. The computer is a December 2007, iMac 24” with 2.4 GHz Intel Core 2 Duo, 4 GB Memory, s/w version 10.7.5; Disk Capacity 319 GB, Available 117 GB. Macintosh HD has alway been the system disk, does it now have an identity crisis? Would reformatting the disk mean Erasing it? Exactly what do I do in Disk Utility to “reformat” the disk, I don’t see that listed on the menus. This computer is getting cranky, I no longer Shut Down at night, only Sleep. If it’s Shut Down, the next morning I am treated to a white screen, for a long time, before it finally shows me the Log On Screen. Suggestions would be appreciated.

RRFS - This took me a long time to finally get to a fix. Your reply led me to investigate the Repair Disk Partition - as it turned out there wasn't one; the HardDrive was going bad slowly. The 10 to 40 minutes it took to startup in the morning, was the HD trying to find it's way. I had the 320GB HD replaced with a 2TB HD. All is OK now. Thank You very much!! Also, the Apple store geeks couldn't make it better but the locally owned Apple retailer did just great with it. from San Luis Obispo County - Peace.

External Drive Format - Mac Extended vs Fat32

Hi
There seems to be a general consensus that if you are saving iMovie projects to an external hard disk, the format must be Mac Extended (Journaled).
There is an Apple support article from July 2003 saying that this is the case.
However I have experimented, testing an imovie 6 project saved on both a Mac Extended partition and a Fat32 partition on my external drive.
Both appear to run perfectly.
Does anyone know whether the article / idea that iMovie needs Mac Extended format is out of date? Has subsequent releases of iMovie fixed the issue with using Fat32?
Any experiences/thoughts anyone? I'd ideally prefer to keep my external as all Fat32 seeing as I want to swap files with my PC.....

Why not partition the drive, one partition Mac OS Extended, one partition Fat32, as suggested in another thread?
BTW, I wouldn't rely on your experience storing an iMovie project on a Fat32 drive to prove much of anything. If Apple says not to use it, I wouldn't use it. There's no way any one of us can test all the conditions that can and will arrise.
One such condition, if memory serves, is that large clips — longer than 20 minutes — do not import correctly with Fat32. Something about a 4GB limit, if I recall. Users have reported other problems too. A search for "Fat32" in the iMovie forums should reveal several.

Capture Problem (av-1) - Mac OS Extended formatted drives

I've got a bit of a stumper. I've been trying to capture some video. (I'm backing up all my Hi8 tapes to DVD.) I have no size limit enabled. The time limit is set to 30 minutes. When I finish, FCP stop the capture and creates the capture files. I have one 4.1GB file (Untitled) with the movie and sound and another 780MB file (Untitled-av-1) which is not playable. The movie file plays with quick time and is able to be edited with FCP. But, the other file does nothing. If I delete the second file, the first movie becomes unplayable and uneditable in FCP.
I searched this issue. I do not have Norton AV or any virus protection software. All my drives are formatted MacOS extended.
I don't know why else this extra file is there? Anybody know? I've captured files before and this did not happen. Strangely it's happening now.

Well, you did mention...
so I don't understand why it's (apparently) running into a problem peculiar to FAT32-formatted drives
I kind of had to assume at that point the source drive was the one you formatted as Mac OS Extended two years ago, and the target drive was FAT32. If not, then I'm not sure why you mentioned FAT32 at all.
In that same thinking, error code 0 is directly related to FAT formatted drives.

Format: Mac OS Extended
