Mac OS Extended

I am setting up a RAID5 4disk raid and have bought 4 seagate 1.5tb hard drives for the raid unit.
I erased the disks (in the raid unit) to use them on Mac OS but the top disk image in disk utilities is showing up as Mac OS Extended (journaled) whereas the bottom disk image is showing up as Mac OS Extended.
I sent an email to Wiebetech and they said that they recommend the use of Mac OS Extended as they have found this more efficient but I just wanted a second opinion before I start to use the unit.
1. is it normal to have the top disk image as (journaled) and the bottom one as just Extended.
2. which is best for a raid set up, OS Extended or OS Extended (journaled)
Any help and advice would be much appreciated.

The current disk formats are irrelevant - they will all get erased when added to the array.
1. is it normal to have the top disk image as (journaled) and the bottom one as just Extended.
You can use whatever combination of individual drives you like - the OS will happily support Mac OS Extended, Journaled, case-sensitive, case-sensitive+journaled, FAT32 and UFS all at the same time - at least on different volumes. But as I said above, as soon as you merge multiple physical drives into one logical array, any existing format is lost anyway.
2. which is best for a raid set up, OS Extended or OS Extended (journaled)
I don't see any reason to use anything that isn't journaled. Journalling adds a very slight overhead to disk activity, but makes startup and data recovery far faster. If your drive is unmounted 'dirty' - e.g. you crashed, or pulled the cable inadvertently - the OS only has to review the journal for recent changes to verify the state of the disk. Without the journalling it has to examine the entire drive which could take several minutes next time you boot up - and this takes longer the larger the disk size, of course, since there's more space to examine.
In most cases the journalling overhead is insignificant and immeasurable by normal humans.

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.

Greeting,
I want to reformat my external hard drive using Mac OS Extended (Journaled, Encrypted ) but before formatting it, I want to make sure that if I loose the hard drive or the hard drive get stolen, no one will be able to retrieve or recover the information on it so could you tell me what kind of encryption will be used or is there any way to recover the information?
Thanks!

I think FileVault is used to encryp internal hard drive but I wanna encrypt an external hard drive with Mac OS Extended Journaled Encrypted which is completely different!

How can I transfer my iphoto library from a Mac OS Extended (Case-sensitive, Journaled) harddrive to a Mac OS Extended (Journaled) hard drive?

Community,
Every time I try to transfer my iphoto library from a Mac OS Extended (Case-sensitive, Journaled) harddrive to a Mac OS Extended (Journaled) hard drive, I receive the attached message: "You can't copy 'iPhoto Library' because it has the same name as another ideon on the destination volume, and that volume doesn't destinguish between upper- and lowercase letters in filenames."
My theory is, if I am able to unpackage my iphoto library, I can transfer each folder one at a time so that I can trouble shoot any "duplicates." Will this work?
Let's say that works. How can I repackage the library so iphoto recognizes it?
Is there a better way?
Thank you,
Jonathan

Can we assume that I don't have any naming conflicts? Clearly there are or else I wouldn't get the error I'm getting.
The error doesn't mean you have name conflicts. It means that the Finder won't take the chance that you might have them.
You're suggesting that all I would need to do would be to use Carbon Copy Cloner to transfer the files from the case-sensative harddrive to my Extended Journaled harddrive?
Yes. But I would just use the built-in rsync shell command. First, back up all data if you haven't already done so. Launch the Terminal application by entering the first few letters of its name into a Spotlight search. Copy or drag -- do not type -- the line below into the Terminal window, then press the space bar:
rsync -aE --delete
Now drag the iPhoto library you want to copy into the window. You should have something like this:
rsync -aE --delete /Users/you/Pictures/iPhoto\ Library
Drag the Pictures folder on the destination volume into the window. Now you have this (line will wrap on the page):
rsync -aE --delete /Users/you/Pictures/iPhoto\ Library /Volumes/something/Users/you/Pictures
Press return. The copying operation will start. When it finishes, you'll see a new dollar-sign ("$") prompt below what you entered. If there were no errors, you're done.

How can I partition my external hard drive into NTFC and Mac OS Extended Journaled?

I brought a 1tb external hard drive from Western Digital. It currently have one partition which is Mac OS X (Journaled). I want to have two partition, one Mac OS Extended (Journaled) and one NTFC for Windows. When I try to choose 2 partition and choose a partition type, I only get the following choices:
1. Mac OS X Extended (Journaled)
2. Mac OS X Extended (Case-Sensitive, Journaled)
3. MS-DOS (FAT)
4. ExFAT
5. Free Space
I don't want to use MS-DOS (FAT) because I am limited to only 32gb of space and I need plenty of space for Windows files.

Assuming that entire drive is GUID and you keep the existing journaled partition.
Make a second partition that is exFAT (more storage ability than FAT) using DU.
Then mount the drive on a Windows 7 and reformat that exFAT as NTFS. But remember that Mac can read and write exFAT natively, but cannot write NTFS without special software. Perhaps exFAT is what you want.
But more the the point: is the journaled partition used as a backup device? If it is, I would leave that drive alone as a backup drive and use a second device for "data only" sharing between types.

How can I migrate an Aperture library from an external HDD with Mac OS Extended (Journaled, Encrypted) format?

How can I migrate an Aperture library from an external HDD with Mac OS Extended (Journaled, Encrypted) format?
I used to store my pictures on an external hard drive using the latest version of Aperture. Now I tried migrating my Aperture library to Photos. However, after a short moment an error message popped up telling me that "Photos was unable to make a copy of your library before preparing it. Photos does not have the necessary permissions...".
My external HDD doesn't need any permission repairs nor is the system prohibited to read from or write to it.
Thanks for any advice in advance!

My guess is that the encryption is the problem for the new app.

I need help with boot camp. "Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again."

This message appears every time I try to partition my disk:
"Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again."
I verified my Macintosh HD disk on Disk utility and then tried to repair it, but I am unable to click the repair button.
It says it's not available because the startup disk is selected.
I don't know what to do or how to go about both these problems.
Please, any suggestions?

How to format external drive to MAC OS Extended w/ MBR scheme?

Hello all,
I have a Maxtor 1TB drive that I would like to format to MAC OS Extended (Journaled) but also using a Master Boot Record partition map scheme.
Every time I try using the Disk Utility, I get a partition error. It will only let me partition using a GUID scheme, however the XBox360 that I also connect my drive to requires a MBR scheme.
I have another another Maxtor drive formatted in this manor, so I can't quite understand why I keep receiving this error!
Any help would be much appreciated. Thanks

Not doable. AFAIK, your choices are APM, GPT, and MBR. Additionally, HFS+ isn't available for windoze's MBR; only MS-DOS or FAT-32.

Unable to format external hard disk as mac os extended (journaled)

Have just bought a 750gb Western digital HDD. To be able to use it to store video to use in i movie it needs to be formatted in mac os extended (journal). However when I try to do this in disk utility I get a volume erase error reporting an error on exit. the resulting disk is then unreadable until it is formatted back to MS-Dos (fat) again. Any tips or have I just wasted my money on a disk that is not compatible. On the box it says it is compatible with OSX 10.2.8+?

Try the directions in this article. They are for formatting a drive for Time Machine but will work just fine for your purposes.

Unable to format external drive as Mac OS Extended

I just bought a WD 3TB My Book Essential external hard drive so I can free-up space on my Mac Mini. When I used Disk Utility to erase the data and reformat the drive as Mac OS Extended, I got the following error:
+Disk Insertion+
+The disk you inserted was not readable by this computer+
There were three options; Initialize, Ignore or Eject. Choosing either Initialize or Ignore resulted in the following error:
+Disk Utility Internal Error+
+Disk Utility has lost its connection with the Disk Management Tool and cannot continue. Please quit and relaunch Disk Utility+
So I Googled it and found the following thread http://discussions.info.apple.com/message.jspa?messageID=11461203
This suggested using First Aid; Repair Disk. When I ran this, I got the following error:
+First Aid failed+
+Disk Utility stopped repairing “disk4s1” because the following error was encountered:+
+Filesystem verify or repair failed+
I'm stuck; does anyone have any ideas how to resolve this?!

Not sure what the problem was on the MacMini (10.5.8), but I just managed to format the disk on my MacBook Pro (10.6.4).
Problem solved!

How to format FAT drive as MAC OS EXTENDED?

Hello,
Does anybody can help me to format a FAT drive as MAC OS EXTENDED? It is an external FW drive. I cannot find the way in the laptop.
Thanks!!

I've discovered one subtlety with Disk Utility that wasn't at all apparent until I smashed into it headlong. I have a number of machines that have been running Tiger Server since the day it came out, incrementally updating from 10.4 to 10.4.11 as each release came out- so I have a number of 10.4 install disks to support them. I have also been painstakingly backing them up weekly via SuperDooper to emergency firewire backup drives, so that when disasters would occur I could theoretically simply reboot from the external drive and keep going.
At some point, Apple changed both Disk Utility and the requirements for a bootable external disk, and apparently I didn't get the memo. The old Disk Utility present on the original 10.4 disks lacks the "Options" feature found on the current one under the Partion tab- which allows the user to select the partition table format. There are now three options: Master Boot Record (FAT/DOS), GUID Partition Table (used to support the Intel OS X machines), and Apple Partition Map for the PPC machines.
Regrettably, PowerPC machines running 10.4.11 apparently *will not boot* from disks reformatted from DOS/FAT as Mac OS X Extended with the old disk utility, as I found to my woe when I installed Security Update 2008-008 and all my Server machines stopped working. They appear on the list of bootable drives when booting in select mode, they appear in the list for selecting the boot disk in System Utility, they can be selected- but the machine will simply not boot from them. The old utility apparently used to leave the FAT/DOS Master Boot Record partition table in place when reformatting to Mac OS Extended. I discovered that it was necessary to use the new utility, and specifically go into the options and select "Apple Partition Table", if you intend to be able to boot from an external drive reformatted from FAT/DOS with 10.4.11-era machines. And it should be noted that the new disk utility *does not* do this table selection by default: you have to use the Options button under the Partition tab and set it appropriately yourself.
Consequently, I spent several days reformatting, repartitioning, changing partion table types, and recloning my backup drives so as to render them bootable once again under this apparently new scheme. So, as a word to the wary: if you have been maintaining bootable external drives since the early (perhaps pre-10.4.7) releases of Tiger, it would behoove you to take a few minutes to go make sure that they are actually *still bootable*- and correct this gotcha before you run into it in an hour of need.
The other bad news if that, if you have the original 10.4 Server disks, "Archive and Install" does not appear to be an option, and you only have a disk utility that can't produce a bootable external disk in any case when booting from them. So it can be a painful exposure.

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.

External HD with Mac OS Extended and FAT32

Hi,
I have partitioned my external harddisk using Apple's Partion scheme into 2 partitions. The first I formated as Max OS Extended (Journaled) and now I would like to format the second as FAT32, but somehow this is not possible: either I can choose PC Partition scheme and resign using Mac OS Extended or use Apple's Partition scheme and resign the FAT32 part.
I would like to use the first partition as a backup for my Mac and the second to transfer data between Mac and PC - sort of a big memory stick
Any suggestions please?

good tip! Doesn't look too complicated, but uncomfortable if one has to mount the disk manually each time.

Format External Drive with 2 partitions (NTFS & Mac OS Extended)

I have a 300GB external hard drive. I need to format it into 2 partitions so I can backup my PC and my Powerbook.
I need two partitions:

Reformatting external drive to Mac OS Extended but maintaining RAID setup

Hi again,
I am considering taking the leap finance-wise and purchasing [this external drive|http://www.amazon.com/Western-Digital-WDH2Q20000N-Studio-Interface/dp/B00 16P7H3Q/ref=cmcr_pr_producttop]. It comes pre-formatted to HFS+ or something, so I guess I will need to reformat it to Mac OS Extended to use it with FCE.
So here are the questions:
*1. Would it make more sense to use it in RAID 0 mode for faster speed, or RAID 1 mode to keep a safer backup of my files?*
*2. Would reformatting it to Mac OS Extended for use with FCE still allow it to use normal RAID abilities?*
I realize this is not the right forum for posting this, but I thought someone here might be knowledgable about backup in general and how to best format an external drive for use with FCE, while maintaining the ability to have a "mirrored" RAID setup. Any thoughts?
Thanks in advance,
Sasha
Message was edited by: skalicki`

So just one more question because I'm pretty new to this whole RAID thing:
Say I formatted the drive to RAID 1 so in theory I have 1TB of space that is "mirrored" over to the other external drive.
*When I ingest my footage, will copies be stored to both drives, so if one fails, I will still have my media?*
I gathered this was the idea but didn't know how it works with FCE.
