Hi mwachel,
Sounds like your drive is corrupted. I suggest backing up all data off it, then doing a format with the "Zero out all data" security option checked, then copying your data back on.
If you can't get to the data currently and it is important, you can try using DiskWarrior to recover it, or a commercial disk recovery company.

Can't Eject Firewire drives

I've been using a collection of 500GB firewire G-Drives for pro-audio & time machine backups.
Up until now, they work great with my old 2006 MBP (OS 10.4) , and my late 2008 MBP (OS 10.5.6)
I just got a new 2009 MBP with Leopard 10.5.6 and whenever I mount the drives, I cannot eject them.
Its a mystery. No applications are open. Spotlight is not running. Everytime I try to eject a drive I get a message saying its in use.
My only remedy is to shut down the computer, and turn them off.
Any ideas?

Means corrupted system files. You should reinstall OS X. You may try this:
How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then quit DU and return to the installer.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.

What can make my Firewire drive unbootable?

I have a 17" 800MHz iLamp. Here's the situation: I do a complete backup of my HD to an external Firewire drive using Carbon Copy Cloner. Now, this used to work just fine, but at some unknowable point in the past, something changed. Now, if I choose the external drive as my startup disk, it won't work. When I restart I get the grey apple screen with the spinny thing, it thinks for awhile (2-3 minutes or so) and then the apple changes to the circle-slash "no" symbol.
The thing is, that same external drive will boot my other machine - a 933MHz G3 iBook - just fine. The problem is somehow specific to the iMac.
I'm running 10.3.9.
The data on the backup drive seems good otherwise, and I have tried repairing privs post-backup, to no avail.
Any thoughts on why this might be?

Nobody really knows. There's lots of posts in here about it.
Some people are re-installing, going back to 10.4.3. You'd have to archive and install, upgrade to 10.4.3 with the COMBO drive and consider updating your Quicktime.

MacBookPro:Can you add firewire drive & video device at same time?

I want to buy a MacBook Pro 15" to edit on FCP and FCXpress, but i am concerned that there is only one Firewire Bus (and plug). I have a Canopus AVC 100 and an external firewire 400 drive and want to use both at the same time. I have always been told that you have been told you can not add a firewire video input source or a hard drive on the same firewire bus. The internal drive is not big enough for my projects and I want to capture directly to the external drive. I have been looking at several solutions, such as adding an ExpressCard-ePCI to give me an additional Firewire Bus. (The FireWire 800 addition would also be a bonus.) Are the two Firewire ports (400 & 800)on the 17" MacBook Pro on the same bus (resolving this problem)? I am looking to see what other editors are doing to solve this issue?
867x2 Mirror Door G4 Mac OS X (10.4.7)

You shouldn't have any problems either
I field dozens of questions each week with issues on desktops and laptops due to the single FW bus limitation.
Glad it works for you, but please don't assume it will work in all configurations.
Some cams and FW devices do not play well together.
For less than $80.00 you can get a ExpressCard/34 firewire card.
I believe it's a good investment, particularly for the high overhead in FCS 5.1.

Disk Utility says it can't repair hard drive...now what?

I managed to get Disk Utility to run the Repair, but it gave me a message that said after 3 attempts to repair the disk, it was unable to. Repair failed. Now what do I do? Any thoughts?

Ah, I see your other post is a duplicate of this thread. Regarding the "underlying task reported failure" message, are you getting that with respect to "temp#####" files? Per Using Disk Utility in Mac OS X 10.4.3 or later to verify or repair disks, you can ignore those messages.
DiskWarrior can often make repairs that Disk Utility cannot.
If you have access to another Mac, you can try FireWire target disk mode to backup/recover the eMac data.

Can't repair fusion drive/install OSX

I have an imac with apple installed fusion drive.
I was having problems so decided to wipe the drive and reinstall mavericks.
I booted into recovery mode and erased the drive, then chose install osx.
the download started and got to the end then an error message appeared saying could not install.
I tried same process again to no avail.
I went back into drive until and checked recovery partition and hd, both verified ok, but when I clicked on the top level (both drives joined) it said the drive needed repair. I ran the repair at this level but kept getting a repeated message to repair drive.
I did a restart into recovery again, but this time it took me to internet recovery?
I tried installing osx from this point but it wasn't offering mavericks, but mountain lion. This also failed.
I tried erasing the disk but this failed saying it couldn't unmount.
I also tried to restore from time machine, which also failed!
So I'm big time stuck, anyone got a suggestion please?
THanks

Since posting this I have managed somehow to get the drive working again.
I think i did it by breaking the link between the SSD and HDD, then used disk utils to repair the problem and join them back.

Can't see FireWire drive as a network drive

I am trying to share a LaCie 250 GB Fire Wire hard drive over an all-Mac network. The drive is FAT32 formatted. I am not able to modify the permissions for the drive. When I log into the computer that has the drive connected, the Fire Wire drive does not show up as an available network drive.
Any ideas?

Since you are all Mac, might try formatting as OS Extended (journaled) for starters.

IBook wont boot up from Firewire Drive - it used to

I've been struggling with my G3 iBook for the last few weeks. It's a long story...
My initial problem started when the beachball started spinning and spinning for the smallest little thing. I would have a single program running but it would still keep spinning. I repaired disk permissions and ran MacJanitor. MacJanitor would take more than 40 minutes to complete running. It usually used to take less than 5 minutes.
I called the local Apple dealer (no Apple Stores here) and they suggested that I reinstall the OS. I reinstalled the OS, but that didn't result in any improvement. A few days later I got a warning from the HDD S.M.A.R.T. status saying that the internal HDD was failing.
I didn't have a backup of my internal HDD so I went out and got myself an external 3.5" Firewire HDD. I then used Carbon Copy Cloner to clone the internal drive to the HDD. Cloning itself took about 8 hours - I assume because of the problem with the internal HDD. I then went to the system preferences to make the external HDD as the startup disk. I then erased the internal HDD. My iBook was booting up and running at normal speed using the external Firewire HDD.
Last night I noticed the beachball spinning again. It was late so I shut down the iBook. When I tried to startup the iBook this morning , the Apple symbol came up on the screen, and a few minutes later a Circle with a slash symbol across it. The iBook would not boot up. I tried this a couple of times with no success.
I reinstalled the OS on the internal HDD - took about 3.5 hours. I am now working off the internal drive. When I plug in the Firewire drive it shows up on the desktop. When i go to system preference I can select the Firewire drive as the startup disk - BUT when I restart the iBook it does not boot up from the external Firewire HDD. I also noticed that I cannot access my documents, pictures, MP3's on my Firewire Drive when I look through the contents - Did I lose them, or just don't have priveleges??
I am not sure what the problem is and why the iBook refuses to boot up from the external firewire drive. The internal drive still shows the SMART status as failing, and I am not in a position to replace it right away. I need to be able to get my iBook to boot back up from the Firewire Drive.
Please help
Thanks
Vir

I managed to get the problem sorted out.
I first started the iBook from the internal HDD and then went to System Preference to select the startup disk. I selected MAC OS 9 on the external HDD as the start up disk.
The iBook started up from the external Firewire drive using OS 9. OS 9 also showed that the iBook had not sut down properly the last time and verified the disk. Once I got the iBook started in OS 9 I went to the Control panel and then to Startup Disk. I noticed that I had 2 versions of OS X on the external Firewire HDD - one which said "OS 10.x.x previous system" and another which said OX 10.x.x. (When I select startup disk from OS 10.x.x it does not show both these options, only OS 10.x.x) I remembered that when I was reinstalling the OS (as recommended by the Apple Dealer) my settings etc were saved as "previous system". I seleected "OS 10.x.x " not "OS 10.x.x previous sytem" on the external HDD and re-started and it booted up ok.
My question here is - why does this additional startup option show up on OS 9 but not on OS 10? I figure that the iBook was trying to startup from OS "10.x.x. previous system" when it actually should have needed to startup from "OS 10.x.x.". This problem must have occured when I shut down ...
Is it ok to delete the OS X.x.x.previous system folder without losing any data etc??
Thanks

Disk utility can't repair this disk.... Is it still possible to back up my files?

I was just on Word earlier and the mac crashed, I restarted it and it wouldn't load past the grey screen. I then used my install disc to go into disk utility, where it tried to verify and repair my Macintosh HD but failed to do both. I don't know what's cause this but more importantly I need to know where it's still possible to back up my files without having to purchase Disk Warrior. If I was to take it to the Apple store, what would they suggest?
I don't know what my operating system is, I recently did a system update last week I believe if that means anything?
Thanks for your time
Luke

Okay thanks Thomas Reed, it's a shame this has happened. It was so sudden...one minute I'm typing on word, the next minute it's broke beyond repair?
It's peculiar how it says Disk Ultility can't repair the drive but to try and back up your files...when it's actually impossible to do so without any software. I'm assuming things like creating a new image etc. won't help at all.
I'm hoping the Apple Store people will be able to help me out, I've heard DiskWarrior is good so I may check that out.

How to boot from external firewire drive

Apparently my internal HD on the powerbook has died as it repeatedly gives me the black screen "restart" message and re-install of system software fails.
I have an external bootable firewire drive, which is a "carbon copy" of my iMac, however, it's SnowLeopard not Leopard, so is there any way I can use the firewire drive to boot off of on the G4 or any other suggestions?
Also, does anyone know what Apple typically charges to replace the internal drive in the PB G4? I looked at the video for doing it myself and that is not an option for me.
Thanks!

The black screen restart message, or kernel panic, can be caused by a number of causes, most which are typically hardware-related, and many times a problem with memory. Try re-seating the memory to see if that makes a difference.
This is a good read on kernel panics: http://www.thexlab.com/faqs/kernelpanics.html
If you have the original OS X disks that came with the system, find the first one that should say 'AHT Version x.x' in small print on the label. Insert it and reboot while holding the alt/option key down. Choose the Apple hardware test, and when prompted, choose the extended test. That might give you some additional information on any hardware issue(s).
You can't use your Snow Leopard bootable drive on the Powerbook, as Snow Leopard requires an Intel-based system.
If it turns out it is a hard drive issue, be aware that Apple will keep your current hard drive as a trade in on a new drive. Some people have private data on the hard drive and have a concern with it leaving their ownership (even if the drive isn't working).

I recently downloaded is x mountain lion and while it finished it erased all my data, some of which I need. When using disk utility I found my old data but it says corrupted. I can't repair and while restoring the error code 32 Broken Pipe appears. Help?

My data I need is on my computer but it needs to be repaired but can't and when I try to restore it/back it up it ends abruptly with error code 32 broken pipe.
It was damaged while installing os x mountain lion and I found my data on disk repair (utility)

Sounds like your hard drive is badly corrupted, likely due to problems that were already there when you started trying to install Mountain Lion. The problem is, if you don't have any backups already, you may not be able to recover all your data from this state. Do you have backups of that data already?
If not, I assume when you say that "it needs to be repaired but can't," you mean that Disk Utility tells you there is a problem with the disk, but that it is unable to repair it? If so, you can try repairing the drive using DiskWarrior, which can repair problems that Disk Utility cannot. That may give you access to your data again, but may not.
Also, it's important to understand that if your data is not backed up, everything you do with the computer runs the risk of overwriting or corrupting that data. You may want to go straight to trying to recover your data. See Recovering deleted files.
Regarding the error code, if you're trying to back up the drive using Disk Utility's Restore tab, note that that is often not successful when the drive you're trying to back up is corrupt.
Once the situation is resolved - either because you have backups, are able to recover your data files or are forced to accept that they are gone permanently - you will need to erase the hard drive and reinstall the system and all your apps from scratch.

Post 10.5.8 Update - can't repair permissions on external HD

Just had a rocky time updating to 10.5.8 on my iMac. Install took a long time and did 2 restarts.
Once back in business, Time Machine failed to back up saying I didn't have write permissions on my external WB 160GB drive connected by USB. Checked Get Info and indeed it had changed to read only permissions. This volume had worked with TM fine since it was connected in Feb this year.
A restart restored Read/Write and TM ran successfully, but took a long time to back up 1.3GB. Thought I would do repair permissions on this drive but both Verify and Repair disk permissions are greyed out.
It may be that they've always been greyed out and I've never noticed or checked?
Can advise whether this is normal to be unable to verify/check permissions on an external USB HD please??
thanks,
M

You cannot repair permissions on a non-startup drive because there are no permissions to repair. You can, however, repair the drive were it suffering some kind of directory failure.

Networking Firewire Drives

I have a new MacBook Pro and Time Capsule as well as an older iMac and three firewire drives. Is there any way to network the firewire drives to the Time Capsule without having a physical connection? Any advice would be appreciated, as I am new to networking.
Here is what I have done. The MacBook Pro and TC are networked wirelessly. The firewire drives are connected to the iMac, which is connected directly to the TC. This works very nicely BUT I would like to dispose of my iMac. Is there any way I can connect the firewire drives to the wireless network without physically attaching them to the iMac or MacBook Pro?

I have a firewire HD; Acomdata, that I used as backup my emac. Then I got a Macbook, and a Time Capsule to go with it. I have the firewire drive connected to the macbook, and the macbook wirelessly to the TC. I have been transferring files over to the TC via firewire.
All of this because I don't really trust the TC which took way too much trial and error, and lots of advice to get hooked up. Even then, the backups have been very erratic. I can't use the firewire drive as an extra backup unless I allow time machine to wipe it clean first. (I'm awaiting TC updates to hopefully iron out some of these bugs, Time Capsule seems to be infested with them-ha-ha)
I don't know if that helps... but the bottom line is "Yes, my TC is connected to my firewire drive."

Can't repair disk using Disk Utility

Hi, my MacBook (10.7.6) was freezing frequently and I was not able to use Command+Option+Esc to safely force quit. I would only be doing light Internet surfing whenever the laptop froze. No new software or hardware installed recently either to cause the problem. Anyone encounter this problem too?
Tried using Disk Repair and this is the message I get: disk utility stopped repairing macintosh HD. Disk utility can't repair this disk. Back up as many of your files as possible, reformat the disk and restore your backed-up files.
Under the details of the disk repair process, the following items were highlighted in red.
1. Checking volume bitmap: volume bitmap needs minor repair for under allocation
2. Checking volume information: the volume macintosh HD was found corrupt and needs to be repaired.
Volume repair complete.
3. Updating boot support partitions for the volume as required.
Error: disk utility can't repair this disk...restore your backed-up files.
Appreciate any help you can give on what the underlying problem could be and how to reformat the disk now.
Thanks in advance!!

You have OS X Lion, so you don't need a DVD, just start from Recovery.
1. Press Command and R keys while your Mac is starting and open Disk Utility.
2. Select Macintosh HD in the sidebar and repair the drive.
If it can't repair the drive:
1. Make a Time Machine backup.
2. Press Command and R keys while your computer is starting, open Disk Utility, select Macintosh HD in the sidebar, select Erase tab, erase the drive and close Disk Utility.
3. On OS X Utilities window, select the option to restore the backup and follow its steps

Can no longer repair permissions using firewire drive

attempting to boot from a firewire drive with 10.6 to repair permissions of a different 10.6 drive no longer works.
even though there's an OS on the drive, when launching Disk Utility, the Repair Permissions button is completely greyed out unless you select the actual boot drive
looks like we might now ONLY be able to repair permissions using the 10.6 boot disc
