The correct Ownership & Permissions on external firewire disks?

I was excited by a resolution to the same problem I have (I don't know what Ownership & Permissions I should have on my external -- bootable -- HD). Mistakenly I used Leopard to set them up rather than Mac OSX 10.4.11. Now I no longer had access to the HD nor would it show up on the desktop on Mac OSX 10.4.11 although the Disk Utitlity showed that it existed. I finally erased and cloned the disk but don't know what Permissions I should set it at. "Niel" supposedly answered this problem but his answer was "click here and follow the instructions" which does not show up on the forum. I can't find any other discussion of my specific problem nor an explanation of various permissions sets for Hard Disks internal nor external. If someone could help me I would be grateful. I am in Japan far from any Apple Stores or shops. Thank you.

For a bootable drive or system drive:
owner=system w/read-write privileges
group=admin w/read-write privileges
other=read-only privileges
The box labeled "Ignore permissions on this volume" should be unchecked.
To set the ownership and permissions select the drive and press COMMAND-I to open the Get Info window. Click on the small triangle where you see the label: Ownership and Permissions.

  • External FireWire Disk will not boot

    Hi Forum,
    after some installations (OS 10.4.9, latest security update and Qucktime 7.1.6 I canot boot from my external disk (Lacie) connected to FireWire 800 port. The Apple shows up but then nothing more happens. Does anyone have a hint?
    Thanks

    Add me to the list also. I had an external firewire disk as a RAID mirror for my boot disk. After a system crash (and some problem with my internal disk) I couldn't boot from the firewire stripe. This used to work.
    I've tried creating a single-disk "degraded RAID pair" on the external disk and cloning the internal disk to it (using Disk Utility "Restore"). The cloning works fine but I can't boot from the copy. This is how I originally set up the RAID pair (clone, boot from clone, add internal disk to RAID group). This used to work. I bought a new firewire disk and it has exactly the same problems.
    My original firewire disk was an Acomdata E5. My new firewire disk is a Coolmax Gemini CD-311 enclosure with a Hitachi 250GB deskstar inside.

  • Install Solaris on External Firewire Disk

    Hello All,
    I have a laptop running windows 2000 and I have a External Firewire Hard Disk of 60 GB. Now my question is, " Is it possible to install Solaris 8 on this external Firewire Hard Disk". When I tried installing, It did not find the external Firewire Disk, the only partition information, which solaris was displaying was from my internal Hard Disk.
    Please give me clues/information, how should , I do it.
    Thanks

    First off, is any of your Macs an Intel Mac, that will complicate matters since they use a different hard drive formatting and need a different installation of Mac OS X.
    Secondly, you can't directly install Mac OS X from an Intel Mac to an external hard drive, you have to do a clone with a software like Shirt-Pocket's Superduper for that.
    If it isn't an Intel Mac, perhaps your Firewire hard drive isn't Mac OS X bootable? Not all are.
    Here's a hint on making the Intel/PowerPC partition table:
    http://www.macosxhints.com/article.php?story=2006061610374449
    Also note, different Macs which came out after Tiger will only boot off the install disk which came with them, and not the retail disk. So you are best off cloning that Mac to its own partition.

  • Can't open external Firewire disk after upgrade to Leopard

    I recently upgraded a PowerBook G4 from 10.4.11(?) to 10.5.5. Now I cannot open its external disk, a LaCie 400 GB Firewire disk, model number 300925, like this: http://www.amazon.com/Lacie-400GB-7200Rpm-Firewire-300925/dp/B00066989Mreport
    The disk's icon appears on the desktop after it is plugged in. After double clicking to open it, the pinwheel cursor spins for a while, then Finder appears to restart, redrawing the desktop. When I have the Activity Monitor open during this, I see a process called ReportCrash run for a while before the Finder reset.
    Does anyone recognize this symptom? Is there a way to see what is being reported by ReportCrash?

    The Genius was skeptical that this was a problem between Leopard and a given disk. Indeed his first test was to boot my laptop from a clean install of Leopard on his own external FireWire drive. Running this way I had no problem opening my external disk from my laptop, running his fresh copy of OSX 10.5.something.
    His theory was that something leftover in my configuration files (in /Library/Preferences) from a previous OS was causing the Finder crash while opening a FireWire disk under Leopard. (Since this machine is four years old, there has been a lot of opportunities for kruft to collect.) His suggestion was do a backup (complicated by the fact that I can't open my backup disk, d'oh!) then to do a clean install of Leopard, and then copy back my user folder.
    I wish there was a smaller hammer I could use, like setting aside some magic .plist file... Any hints?

  • Tiger doesn't install on external firewire disk (partition)

    hi, i've got a Lacie Porche 250GB firewire drive, partitioned in two parts, and i want to install tiger on the first 50GB partition, but the installer give me an error about the destination: "You cannot install Mac OS X on this volume. Mac OS X cannot start up from this volume."
    i'm trying to do this with an ibook G4 and the standard Tiger DVD Install.

    please help me
    iMac Intel\iBook G4   Mac OS X (10.4.8)  

    A boot disk for the Intel Macs needs to have a GUID Partition Table, the G4 needs the "Apple Partition Map". If you formatted the drive on your Intel Mac, you may need to repartition for the G4. In the "Partition" tab in Disk Utility, use the "Options..." button to choose the partitioning. Backup any data on the drive that you need, first.

  • Can't install OS 9 on external firewire disk

    I am running Panther on an iMac G3 450. Some older software and games just don't run correctly in Classic mode, so I would like to install OS 9 on an external firewire drive. The original OS 9 disk from 2000 doesn't run with Panther. When booting from the OS 9 install disk, it can't read the firewire drive. How can I get the OS 9 boot disk to read the external drive for an install? Or - can I install OS 9 on my hard drive without affecting my OS X and all my software and files? Thanks.

    Hi, sageimac -
    The original OS 9 disk from 2000 doesn't run with Panther.
    Correct. The installer on any stand-alone OS 9 Install CD, retail or original model-specific, will not run in OSX - it will run only when the Mac is booted to OS 9, such as to the OS on the CD.
    When booting from the OS 9 install disk, it can't read the firewire drive.
    The OS on OS 9 Install CDs contain the necessary software to 'see' a firewire drive connected to a native firewire port while booted to the CD, provided the drive does not need any additional software. If the firwire port was added via an upgrade card, OS 9 may not be able to see it without additional software.
    When you added the firewire drive, did you reformat it using Disk Utility under OSX? If so, if the option to install OS 9 drivers was not selected, then that drive can not be mounted whenever the machine is booted to OS 9, such as to an OS 9 Install CD.
    Article #106849 - Disk Is Available in Mac OS X But Not in Mac OS 9
    Unfortunately, since in that case the drive probably did not have OS 9 drivers on it previously, there may be no solution but to re-initialize that drive - but it won't hurt to try re-installing OS 9 drivers while booted to the OS 9 Install CD, using Drive Setup's Update Driver function.
    If it is necessary to re-initialize the drive, it can be done using Drive Setup while booted to the OS 9 Install CD, or by using Disk Utility while booted to OSX (be sure to select the option to install OS 9 drivers in this second case. This will erase it, so be sure to first back up your data. In either case select Mac OS Extended as the format.
    Or - can I install OS 9 on my hard drive without affecting my OS X and all my software and files?
    Yes - OS 9 and OSX are designed to co-exist on the same volume.
    You should have no problem doing that, provided there is sufficient space on the hard drive. I do not consider my OS 9 to be overly fat; however, the System Folder still occupies about 0.4 to 0.5GB. OSX runs best when 5GB or so is left free on the drive. So, if you have 6GB or more free space on the internal drive, there should be no problem doing that.
    Use the Clean Install method to install OS 9 from your original Software Install CD (not the Software Restore CD), or from a retail OS 9 Install CD of adequate version.
    Note that a Clean Install of OS 9 removes nothing. It installs a brand new, 'clean' System Folder, renames any already existing one to Previous System Folder, installs a new set of standard OS 9 utilities if they're not already present, and little else.

  • Should I be able to boot from external firewire disk?

    Yesterday, to prepare for upgrading to Leopard, I copied across my hard drive contents onto an external Firewire drive, by using drag & drop, folder by folder.
    I was hoping that this would let me (after a reboot) select the external drive as my Startup Disk in System Prefs, or allow me to choose it if I rebooted holding down the alt key. However the external drive doesn't show up in either case.
    Is there something else I need to do to allow booting via external Firewire? Is that even possible on my PB 1.5GHz (OSX 10.3.9)? Thanks.

    Close, but no cigar! Copying by drag n drop misses invisible files necessary for a boot volume. The way to do this is to use one of the cloning programs like SuperDuper! or Carbon Copy Cloner to copy everything needed to make the FW drive bootable. You can even specify to NOT copy all your files if you wish.
    I go to Versiontracker.com to get these programs.

  • How does the security model work for external USB disks attached to an AEBS

    I've attached a USB disk to my AEBS after partitioning it first on my MBP using Disk Utility. I created a single partition with a GUID partition table covering the entire disk. Next I deselected the "Ignore ownership on this volume" checkmark and assigned myself and my wife read/write access, my group read access, and the rest no access. Next, I hooked it up to the AEBS and created some test files. I noticed in Terminal that the files I created all had rwx access for user, group and others. Trying to chmod that into something less open, like rwx for me, rx for the group and nothing for others didn't work. Also I noticed that when I was logged in the files I had created had my name as the owner, but when my wife logged in, those same files were owned by my wife.
    What is happening here ? Who is the actual owner of the files on the external USB disk on my AEBS, and what are the real access rights (as they seem to depend on the actual user). On my AEBS I've setup "File sharing", "With accounts" and created accounts for both me and my wife, as well as disabled guest account access.
    I get the impression that the owner and access rights seem to depend on the actual user connected to the AEBS, but I'm not sure.
    Can anybody please enlighten me on the subject of AEBS access rights/ownership for USB disks ?
    With kind regards,
    Aloy

    All that I can provide is what has worked for me for years.
    The Time Capsule is setup as the router for the network, connected to a simple Zoom 5431J cable modem.
    Static Internet IP connection from the cable provider is 12.34.567.89
    By default, the Time Capsule is at 10.0.1.1 on the local network
    Port Mapping setup for the Time Capsule is......
    Public UDP Port 8884
    Public TCP Ports 8884
    Private IP 10.0.1.1
    Private UDP 548
    Private TCP 548
    The hard drive on the Time Capsule is accessed from a remote location at afp://12.34.567.89:8884
    The AirPort Extreme is connected by Ethernet to the Time Capsule and is it setup to operate in Bridge Mode
    The AirPort Extreme always receives a reserved local IP address of 10.0.1.2 from the Time Capsule
    The Port Mapping setup (on the Time Capsule) looks like this for the AirPort Extreme.......
    Public UDP Port 8888
    Public TCP Port 8888
    Private IP  10.0.1.2
    Private UDP 548
    Private TCP 548
    The USB hard drive connected to the AirPort Extreme is accessed from a remote location at afp://12.34.567.89:8888
    If you are still having difficulty, I would delete all of Port Mapping settings on the Time Capsule and Update the Time Capsule. Then, go back and setup the Port Mapping for the Time Capsule, check that to make sure that it is working, then setup the Port Mapping settings on the Time Capsule for the AirPort Extreme.

  • 24" Core Duo iMacs and external Firewire disks

    Hi guys,
    I'm having a bit of an issue with the new iMac that I picked up yesterday. There seems to be an issue with mounting disk devices connected to the Firewire 400 port. Disk devices mount fine off the Firewire 800 port. The bizarre thing is that I plugged an old iSight camera into the Firewire 400 port and it works fine. This seems to eliminate both the possibility that the Firewire controller is faulty and that the FW 400 port is dead.
    Just to remove the possibility that it could be a crappy driver, I installed XP via bootcamp but I get exactly the same issue. (although windows is a little more specific. It actually detects the name of the disk device but says it cannot be started)
    I've zapped the PRAM and left the machine dormant and unplugged for 30 mins to no avail. Could someone plug a disk device into their FW400 port and see if they get the same issue i.e. nothing happens? (card reader, laptop in FW target mode, external HDD)
    I'll take the machine back if I have to but I really loathe the though of lugging this thing back to the Apple store.
    Thanks.
    Danny

    I also am having trouble.
    I cannot mount my eMac in target disk mode. The only way I could get the eMac drive to mount was if I put a firewire disk in line with the eMac. i.e. a firewire cable from the eMac to the disk and another cable from the disk to the iMac. (Same model 24" 2.4GHz aluminum).
    I thought the issue was with my eMac, but when I went to connect my Canon CanoScan 9950F scanner the iMac would not see it unless I also went through the firewire drive.
    I have since learned that the drive does not have to be on and spun up, but it has to bridge the connection. The drive I'm using is model PHR-100AF Macally 3.5" enclosure.
    I have been able to mount this drive without having to chain it through anything else. I've also been able to mount a Macally PHR-250CC 2.5" enclusure and a el cheapo 3.5" enclosure that uses the Prolific PL-3507 chip. Also, my 3rd generation iPod mounts just fine.
    I don't have anything for the FW800 port so all my experiences are with the FW400 port.
    My question is:
    Is there something wrong with my iMac that it cannot mount my eMac in target disk mode without being chained to another external drive?
    Is there something wrong with my beautiful, new 24" aluminum 2.4GHz Intel Core 2 Duo imac that it cannot connect to my Canon CanoScan 9950F scanned?
    I expect more from Apple. I expect that it should at least work with their own hardware (the eMac).
    Should I go back to the Apple Store and complain?
    Thanks,
    Chris
    p.s. I guess I should ask my own question huh?

  • External firewire disk partition will not mount

    I have two external hard drives connected by a firewire to my 2002 G4 iMac running OSX 10.3.9. One is a 160GB and the second a 360GB drive.
    I was out of the room when the area experienced a minor power drop in voltage and when I came back the iMac had the message to shut down and restart. When I restarted everything appeared normal until I realised that one partition did not mount on the 360GB drive. I ran Disk Utility to check the disk and it found some issues (I failed to write them down..) but Disk Utility appeared to fix them.
    The disk has 2 partitions and only one of the two partitions will not mount (the second partition works fine!). Disk Utility says that both partitions check OK.
    I have rebooted several times. I have removed all other external attachments and rebooted but still the partition will not mount.
    I cannot see the partition in Finder. The second partition on the disk is available to see and use in Finder.
    I have selected the partition in Disk Utility (grayed out) and tried the "mount" button but nothing happens. For some 18 months up until now the drive has worked fine although I did notice a couple of times it took a while for the drive to open up in Finder and other applications. I use that particular partition daily, it has approx 100GB used of the 150GB total space.
    When I ran Disk Utility it comes up with a variation in the results compared with the partition that has mounted OK. The result of running "Verify Disk" is listed below. The only diffeerence between the two partitions is the first line of each volume. Does the ",0" following "Checking HFS Plus volume." for the first partition called "Genesys1" indicate anything?
    DISK UTILITY REPORT
    Verifying volume “Genesys1”

    Hello! Power failures are murder on disk drive directories as you have found out. Your best shot is to get DISKWARRIOR. It is the "gold standard" for these types of problems and can usually resolve the issue when Disk Utility cannot. As with any utility there are times when even it cannot fix things but it's the best there is at resolving such issues. Tom

  • HEADACHE!!! How to fix the unknown user on my external hard disks?

    I applied 10.5.1 update and now my Volumes permissions are screwed!
    Read thru similar problems in these discussion forums and not sure what the folks are writing about. Too technical for me. I basically know that if I can't correct the permission, I can't write or change stuff I need to do with the external HD.
    I have an (unknown) Read & Write in my external HD's Get Info. I'm unable to remove it. If I tried to add a new name, my Finder will relaunch.
    HELP?!!! Really need a step-by-step guide to fix this problem.

    1. Launch System Preferences and select Sharing pref.
    2. Select File Sharing and you'll see *Shared Folders:* and Users: boxes.
    3. Drag affected Volume to the *Shared Folders:* box and you'll see the users permissions in the Users: box.
    4. From the Users: box, you can add or remove users and correct their permissions.
    Works for me. Didn't have to use Terminal which was too complex for me.

  • I am running iTunes on an IBM comp system Win XP with a 70gb hard disk. I have 4 kids with 4 IPOD Touches. Their apps and album art are eating up the hard disk space. I changed the Media Folder to an external hard disk. How do I get the apps to go their?

    I am running iTunes on an IBM compatible system running Windows XP with a relatively small hard disk (70gb). I have 4 kids with 4 IPOD Touches, multiple IPOD Nanos, etc. Their apps and album art are eating up the hard disk space. I changed the Media Folder through Edit, Prferences, Advances, iTunes Media Folder to an external hard disk. The new music downloads and purchases go there but the apps and other items do not. How do I get the apps and other iTunes software and downloads to go to the external hard disk

    There is no built in function to make this happen.
    Your options are:
    Upgrade the existing hard drive.
    Try creating a link for the app folder on the external drive... this may or may not work.
    Realistically, a larger hard drive is a better solution, then use the external drive for keeping a backup of the ENTIRE iTunes folder and any other personal data on the system.

  • External FireWire disk doesn't mount on Leopard, does on Tiger?

    Hi All,
    I have an external FireWire Hard Drive that mounts as it should on all our Tiger Macs, but is invisible on our Leopard Mac. If we swap the FW cable for a USB2 cable, it shows up.
    Is this perhaps another Leopard 'thing' maybe? Like the one where Leopard couldn't erase a hard drive to FAT 32 like a Tiger could?
    Cheers and thanks in ant...
    Chris

    "Methinks you're perpetuating a myth"
    I'm too long in the tooth to either listen to or perpetuate myths of any kind! Not a myth unfortunately, a weakness in Leopard that was pointed out to me some time ago (when Harry Potter was a boy) by a sage far wiser and way older than you or I - and he was right, and more importantly brought to an end some hours of frustration with Leopard.
    So there!
    Thank you for your suggestions, which have made me think. It can't be the cable because it works with all the Tiger Macs. It might be the slot but if it is, I have two faulty slots which would be rare on a pretty new machine.

  • Access permissions to external hard disks and media players

    I've recently purchased an iMac. I have a number of external disks and media players that when connected are not allowed write access. When I use the disk utility I cannot change the permission from read only. Whats the solution to changing them to read and write access?
    Thanks

    Hi Kieran
    Welcome to Apple Discussions
    You can not write to them because they a formatted windows NTFS.
    See > http://www.macworld.com/article/51972/2006/07/ww_drives.html
    If you want to use an external disk with both PC's and Mac's, you will need to re-format it MS-DOS/FAT-32.
    If you wish to use them with only the Mac's, you will need to Format then GUID partition/Mac OS X.
    See > http://www.kenstone.net/fcphomepage/partitioningtiger.html
    *+Proceed with caution when re-formatting disks+:*
    1. Before re-formatting any drive you will need to backup the current data on it to a computer or another drive, because re-formatting will erase all the data on the drive.
    2. Fat-32 has a file size limit of 4GB and will not allow single file transfers greater than 3.7 or 3.8GB.
    3. You may not be able to change the format or write to many media players without special software.
