Media won't mount via external optical after 10.4.4 update

I did a search of the forums and found nothing related to my problem, sorry if this has already been covered. This is my first post on the support forums, so please forgive me if this is posted in the wrong area, and feel free to point me in the right direction if I should be asking this queston elsewhere.
The subject heading says it all. I have an external Firewire DVD writer, and since I updated to 10.4.4 it won't mount any media when connected second in a chain after my external hard drive. If I disconnect the hard drive and plug the optical drive directly to the iBook, discs mount just fine, but when it is second in the chain ... nothing.
Additionally, neither Disk Utility nor Toast will recognise the optical drive in order to burn data unless the device is plugged directly into the computer.
The obvious solution would be to reverse the order of the devices, so the optical drive comes before the hard drive, but I have experienced problems with hard drive access and speeds of transfer to the hard drive when I've hooked things up in that order, so it is not an ideal solution.
Any help would be greatly appreciated and thanks in advance.

Dear Joel,
for me I have a solution. I had to turn spotlight off with "sudo mdutil -i off" and then to delete all the files in the hidden /.Spotlight-V100 folder and then turn spotlight on again. And then wait for the computer to index again BEFORE the restart. Can be observed in the activity monitor: task mdimport.
I found my solution on the following page:

Good luck to you!

  • My Mac won't mount my external HDD after installing Lion - What can I do?

    My Mac won't mount my external HDD after installing Lion - What can I do?
    HDD: Verbatim 3.5'' External HDD  eSATA & USB 2.0 #48802
    I can not find it in Disc Utilities - so I can not repair it.
    I also haven't found any Driver for the HDD to do an update.
    My Mac is running on the most recent updates of OS Lion.
    The HDD worked before. It contains my former Time-Mashine Backups. I would like to use this drive again. It isn't very old yet.
    It would be much appreciated if anyone could help.
    Cheers,
    Yves

    OK, try restarting in Safe Mode and if that doesn't work try resetting the SMC and PRAM.
    SMC RESET
    Shut down the computer.
    Unplug the computer's power cord and ALL peripherals.
    Wait 15 seconds.
    Attach the computers power cable.
    Wait another 5 seconds and press the power button to turn on the computer.
    PRAM RESET
    Shut down the computer.
    Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    Release the keys.

  • LaCie External Harddrive suddenly won't mount via Firewire 400 or 800

    My LaCie External d2 Quadra suddenly won't mount via Firewire 400 or 800, but will mount via USB 2.0.
    I have:
    Tested the harddrive on another computer and it works fine via firewire.
    Shut down and re-boot. It had no effect.
    Updated all software.
    Note: My MBP will not boot if the Firewire 800 cable is connected.

    I've had a whole heap of strife with my two macally enclosures over FW. I've only got them working twice together, regardless of jumper settings on the harddrives. I can plug either in fine, but if I use both together, my mac shuts down and refuses to boot. One drive is bus powered, the other is powered via the mains
    I wish you luck

  • Filesystem from sdcard won't mount via fstab, will with rc.local

    Since receiving my laptop back from RMA, I've installed my SSD and set up Arch.  I wanted to put /var on a separate reiserfs partition on my 8GB sdcard to prevent extra write activity from logs and pacman, however it wouldn't mount.  I tried using both label and dev (haven't tried uuid yet) and it always failed, causing me to enter admin mode.
    I then set up a 1.5GB partition with reiserfs on the SSD for the time being, changing the pacman cache option to a directory on the sdcard in /media.  I set the command to mount in rc.local and it mounts fine there.  I can't get the other media partition to mount via fstab either.
    Is there another hook I need to add to mkinitcpio.conf and rebuild the init ram image in order for this to work?  Any ideas?  I'm going to try adding usb to the hooks and rebuilding for now.
    Here is my setup:
    fstab:
    devpts /dev/pts devpts defaults 0 0
    shm /dev/shm tmpfs nodev,nosuid 0 0
    LABEL=boot /boot ext2 defaults 0 1
    LABEL=home /home ext4 defaults,noatime,discard 0 1
    LABEL=root / ext4 defaults,noatime,discard 0 1
    LABEL=var /var reiserfs defaults,noatime 0 1
    #LABEL=sdcard /media/sdcard ext4 defaults,noatime 0 2
    none /tmp tmpfs nodev,nosuid,noatime,size=1000M,mode=1777 0 0
    rc.local
    mount /dev/disk/by-label/sdcard /media/sdcard
    mkinitcpio.conf hooks line:
    HOOKS="base udev autodetect pata scsi sata filesystems"
    EDIT:
    I tried adding usb to the HOOKS array between sata and filesystem, rebuilt the image, uncommented my sdcard entry in fstab, and rebooted.  It didn't fix it.
    I see someone made a hook in the AUR:

    I'm a little confused, so maybe I'll learn something here.  It is my impression that /var is not, and need not be mounted while in using the initrd.  It will be mounted in init after the kernel has been loaded, / has been mounted/ and init started.  rc.local definitely is not executed until long after the initrd has been cast aside.
    Things to look at:
    Does the mount point /media/sdcard exist at the time rc.local runs?  I'd wager not.
    Look at the output of ls -l /dev/disk/by-label and recheck the disk labels.

  • External Hard Drive Won't Mount Via USB

    I have a Western Digital (Model #WD2500...) Hard Drive that is about 3 years old. I initially set it up on a PowerBook running Mac OS 10.3.x. I have two newer laptops both running Snow Leopard, and neither will recognize my drive via USB 2.0.
    The weird part is that the drive will mount when connected via Firewire (400 in this case). My newest laptop is on of the new MacBook Pros and it only has Firewire 800. I'm guessing I could probably get a 400 to 800 Firewire cable, but it would be much easier to just use the USB 2.0 connection. Any idea why the drive won't mount over USB 2.0?
    I went to the Western Digital site, and there didn't appear to be any new drivers or firmware for this product. The drive seems to run perfectly well over the Firewire connection, so I don't see what the issue is with USB. The documentation that came with the drive indicates that it should work with USB. This is very baffling to me, so any help would be greatly appreciated.
    Thanks so much!!

    In most external drive enclosures that have both USB and Firewire interfaces, the Firewire interface is able to draw enough power to run the drive. Firewire can provide up to 45 watts and up to 30 volts of power per port (not all devices supply the full wattage; my MacBook model provides up to 8 watts). USB 2.0 and earlier can only provide 5 volts at 500 milliamps (up to 2.5 watts). Some newer laptop drives are at or under 500 milliamps, but just barely, and the enclosure itself needs some power.
    It sounds like the USB port on your enclosure is bad. Firewire is going to provide faster transfer rates anyway, and you don't have to bother with the power supply. Based on your comments, I suspect it still might be a bad power supply, or maybe it's not the right one for the drive. Those things are easy to mix up.
    If you're brave enough to crack the external drive open, what you'll find inside is a standard off-the-shelf hard disk drive, with either a SATA or PATA interface, in an enclosure. You can move the drive to a new enclosure easily.

  • Had a problem copying files, now MBP won't mount the external HD`

    Hi
    I thought to put this in the MBP forum but since I thik it may be the OS I decided to post here.
    I have a newer MBP with OS 10.5, I have an external LaCie c0nnected via eSata to keep my firewire 400 port free. I mounted another external HD to the Firewire port and the computer recognized it and I started copyig some files from the LaCie to the other external. Both formatted HFS+ Files were QT files. Somewhere during the copy process things locked up. I had to force quit the copy process, then coldn't restart the computer so had to ue the boot button to turn it off. Now I can't connect anything to the FW port. The MBP won't mount the 2nd external HD so I can get those files copied. I brought up my FCE and connected the external monitor to the FW port but now that doesn't work either and it was working this morning.
    I hope I didn't blow the FW400 port! Is there any way to 'clear it' in case it's still looking for that HD? I don't kow if I'm asking theright way cause I'm really new to MAC's. I tried the Disk Utility to verify the disk and got an OK message. What else can I try?
    Thanks
    Allen

    Hi VK
    Well I didn't blow the FW port. My video editing partner came over today to discuss a project we're working on together. He has FC Pro and I have FCE4. So I mentioned the problem to him cause it was his HD that wouldn't mount.
    We had FCE open so I was showing him my external monitor fed via the FW port wasn't working either. He went to the View menu then to Video out and then to refresh video devices. BINGO! The external monitor started working. So it wasn't the FW port but apparently the FW was locked up or looking for the other HD. Now it's working. But I haven't tried connecting another external FW HD yet.
    Thanks for your help

  • IMac G5 iSight won't boot from external optical drive . . . FW or USB

    Hello, all. I have an iMac G5 iSight with a busted optical drive. Every six months or so, OS 10.4 eats itself (directory structure goes corrupt), and I need to reinstall.
    The issue I'm having is that the computer won't boot off of my external optical drive. It's not shown as a choice in the Startup Manager, whether it's connected via USB or FireWire. Any ideas?

    Okay, sorry this took so long . . .
    Reset the SMU, NVRAM, and PRAM, no luck. Tried different FireWire port on the iMac, no luck. Tried different FireWire port on optical drive--LUCK.
    Ah.
    Wipe and reinstall got underway, and finished the first part. Unfortunately, my OS 10.4 Disc 2 turned out to be scratched, and wiping the hard drive didn't get rid of the logic board error either.
    Took it to Apple retail store, and it was BOA (bricked on arrival). Astoundingly, it would not power, POST, turn on the fans, nothing. They then replaced the power supply, so they could troubleshoot the hard drive/fan/whatever issue.
    Now the computer POSTs, and they finished the reinstall, and said it passes their advanced diagnostics. I asked them to run the diags on the install CD, so they could see they fan error, and they agreed. That was around 7:00 last night.
    Now, it's still at the store, and I'm eagerly awaiting word on what might REALLY be wrong. Thanks for your help so far!

  • Firewire HD won't mount unless I reboot after being ejected?

    Hiya
    I'm not a Mac newbie, but I am a FW newb. I've used USB 2.0 external drives, but I finally got a MacBook Pro so I thought I'd give FW 800 a go. I got a drive that's designed to work well with Mac's (Seagate) that does USB 2, FW 400 or FW 800. I'm using FW 800, which works fine, however once I eject the drive it won't mount again if I plug it in again to my Mac or my partner's unless I reboot the machine I'm trying to get it to mount on.
    It's quite odd as this wasn't the case with USB 2.0, ie it'd mount over and over without reboots after and eject. Is this how it's meant to be or is something else awry?
    Cheers.

    I was having trouble with my FW 400 burner in SL.
    Check out Ken Marks solution in this thread, it works well:

  • G drive mini won't mount via firewire 800. usb ok

    It hasnt been too long i bought myself a gdrive mini to benefit from the firewire 800 port. It seems that once my macbook gets warm the drive won't mount. It mounts just fine via usb. I've been to the genius bar twice and it worked both times, thats when i noticed it only happens when its warm. I was convinced its a software issue, but i dont know what to think anymore.
    Has anyone encounter this issue? Any ideas of whats causing this?
    Any help would be greatly appreciated

    WAIT WAIT EVERYONE....READ THIS....VERY SIMPLE FIX!
    My G mini 750GB drive stopped mounting.....I tried a million methods to get the G mini drive to mount and searched a ton of forums but never found this VERY EASY FIX.  Try powering down your computer (imac in my case), then UNPLUG the power supply from the back of the computer....VERY IMPORTANT TO UNPLUG COMPUTER FROM ELECTRIC SOURCE. Nothing else worked for me.
    Wait a minute, then plug back in and re-boot....MAGIC - freakin G mini showed up on desk top!
    Good Lord why is this simple fix not all over the G mini site??????  It ought to be on the front of the box when you buy this thing!  Seems no one at G mini sites talk about this and people are sending drives all over for repair! 
    Hope this helps!

  • General problem with (WD?) external HD after latest OS X update?

  • Time Machine won't mount Firewire 800 drive after restart / Finder crashes

    I've been having problems with Finder crashes. I first suspected Spotlight might be the problem because sometimes when I started typing a search, it would display the first 3 characters and then lock up. I could force quit the Finder, but it wouldn't relaunch and required the computer to be shutdown and restarted with the power button. Once restarted, I had no keyboard and no mouse click (the mouse would move across the screen but I could not click on anything). After waiting several minutes (3-5) the mouse and keyboard worked properly.
    After some research suggested the Spotlight index might be corrupt, I forced Spotlight to rebuild the index (add the drive to the exclude list under "Privacy" and then remove it from the list) and then repaired disk permissions. After that Spotlight was noticeably snappier and I thought my Finder crashes had been solved until........
    Part 2: I have been using Time Machine (connected to a Fantom GreenDrive via Firewire 800) for several months now and ever since the beginning, I have noticed that the drive will NOT mount after a restart. I must turn the drive off and back on again to get it to mount. After that Time Machine picks it up and seems to work fine.....well, that is until this Finder crashing thing started several weeks ago. Anyway, I inadvertently set up an experiment last weekend when I installed some software update and forgot to remount the Time Machine drive after the restart. That was last Sunday night. The computer did not crash all week long. I thought my Spotlight fix had finally solved my problems, but now it seems I was wrong. This morning (Saturday, six days later), I noticed my Time Machine drive was not mounted. I mounted it, told Time Machine to "Back Up Now" and went away for a few hours. When I came back the Finder was locked up.
    So guess my question is this: Are there any know problems with using Firewire 800 with Time Machine? and What can I do to fix this? In the meantime I'm trying another experiment - I've disconnect the Firewire 800 connection and replaced it with USB.

    Hi, and welcome to the forums.
    Not in general. Some drives don't always wake or "spin up" fast enough; often that's seen when the system wakes from sleep, though, not so much after a system Restart. Many Western Digitals do that; I don't recall seeing any posts here about yours, but you might want to search the forums for Fantom
    In the meantime I'm trying another experiment - I've disconnect the Firewire 800 connection and replaced it with USB.
    Good plan - that may provide a clue.
    Also, check with the maker -- there may be a firmware or driver update.
    And try verifying your internal HD, and repairing your backups, per #A5 of Time Machine - Troubleshooting (or use the link in *User Tips* at the top of this forum). Either might cause that.

  • 3rd Gen iPod won't mount via firewire - any ideas?

    After working for a brief spell when I first hooked it up, the progress bar would freeze while I was trying to copy files across to the HD. I unplugged, reset the iPod and tried it in my old clamshell iBook, where it worked fine again.
    I tried resetting the PMU on the Macbook, but this only made things worse - the iPod now refuses to mount, despite still working fine on my old iBook. Tried resetting PRAM too but no difference.
    Do I have a duff port? Or could it be an issue with 10.4.6 on the Macbook?

    I tried a JVC digital handycam while on the phone to AppleCare, which it recognised in iChat, and showed a live picture in iMovie. I don't know how I would check for consistency with this device, but it seemed to be working ok.
    I'm connecting via a dock but have also tried connecting direct - all official Apple cables. No difference.
    I'm now noticing new behaviour. When I plug the iPod in it mounts very briefly, triggers iTunes, then unmounts. It stays charging from the Macbook's firewire port, but the 'do not disconnect' disappears and I can use it as if it was only connected to AC. This is reproducible, and is the same if I turn off the launch iTunes option.
    Once again, it works flawlessly with the old iBook.
    I'm almost tempted to go down to the Apple Store in Regent St. and plug my iPod into a Macbook there to rule out software - unless you have any other suggestions?
    Thanks for your continued support.

  • IBook G4 won't mount LaCie external hard drive

    A friend of mine, with a new iBook G4 with 512MB of RAM, is having some problem with an 80 GB bus powered external hard drive from LaCie. The problem he is having is he can't see his drive when he plugs it into his machine. He has tried plugging it in with a firewire cord and a USB cord, and neither have worked. In addition to not showing up on the Desktop the drive doesn't even show up under Disk Utility, however, the drive does show up under System Profiler. When it's plugged in with the firewire cord it says:
    FireWire Bus: Max Speed up to 400 MB / sec
    When it's plugged in with the USB cord, the computer says it sees a LaCie HD.
    He has also tried plugging the firewire drive into another computer, that machine is also running 10.4, and the drive mounts without a problem. He has recently run software update and updated everything that was recommended, repairing permissions before and after each update.
    Any ideas on how to fix this? Or, since it's a new computer should he just take it to the Apple Store he bought it at and have them replace it? Thanks so much.

    Thought you could use this info about getting FireWire to work!
    First, you should always Repair Permissions in Disk Utility before and after any update; I would do that now. If you installed your update with FireWire plugged in, your Mac may not recognize it anymore.
    Try resetting your FireWire ports by disconnecting all FW devices, shut down your Mac and unplug it from AC power (wall socket) for 15 minutes. plug it back in and try FW.
    If that did'nt work, download the combo update from this site (yours may be corrupt), not Software Update, disconnect all firewire + USB devices except keyboard + mouse, Repair Permissions, re-install update, Repair Permissions again + try.
    If that still did'nt get it Zap the PRAM. While restarting Mac hold down the following key combo Command-Option-P-R. Keep holding those keys down till you hear the second start-up chime, then release.
    For those of you with Macs that are not PowerBooks or iBooks, a bad internal battery can cause FireWire to not be recognized, so make sure it's good!
    Good Luck!
    Cheers!
