External hard drive is not mounting via hub

Hi mates,
I bought LaCie D2 Quadra external hard drive and when I connected it to LaCie Huby firewire port it would not mount at all, but when I connected the hard drive straight to my MacBooks firewire port it mounted nicely.
what could be the problem that its not mounting with the hub?

Just tested with USB and it works.
oh.. just remembered that I sync my iPod through one of the Hubys fw ports, so I guess that ports are OK.
Maybe I have a faulty fw cable?

  • External hard Drive will not mount via firewire tpo my Powerbook G4

    I have a Powerbook G4 1.5, 2 Gb Ram and an 80 Gb Hard Drive. Well my problem is, I went and purchased a Western Digital External Hard Drive. The box states that this hard drive is compatible for both Windows and Mac. But for some reason I can't get the external hard drive to mount via the firewire. However it will mount by using the USB.
    So can someone please provide some troubleshooting tips on how I can get this external hard drive to mount?
    Thanks

    hi there,
    in your case, your drive is probably bad because the copy was interrupted. your hard drive may be finished, but more likely, just the file structure is damaged and/or you have bad sectors.
    you have a few options:
    *if you don't need the data back:*
    • see if the drive appears in disk utility and try to erase/reformat (make sure to zero out data to avoid bad sectors)
    • if it doesn't appear, try a pc. it won't recognize it, but it may allow you to reformat/initialize it. then, connect back into mac (which will recognize a pc formatted drive) and reformat as mac os x extended (journaled).
    *if you need the data back:*
    • try a program like data rescue II, file salvage, or boomerang data recovery first to recover the data
    • see if the drive appears in disk utility and try to repair disk
    • if that doesn't work, try disk warrior and/or drive genius
    • if you aren't successful, you may want to try a professional data recovery service (or me first, to ensure that you actually need someone as high tech as drive savers)
    • if you are successful and are able to recover the data, then erase the drive (zero out data) and then move the data back, to ensure you're working off a well formatted drive.
    fyi, if your computer freezes in the future, be sure to try appleoptionesc first and force quitting the problem application. if that doesn't work, try controloption+appleeject (shutdown) and/or optionappleeject (restart). if those doesn't work, in this situation, the next best move would probably have been turning off the power on the hard drive. if that doesn't unfreeze the system in a few minutes, then hold the power button.
    hope this helps,

  • External Hard Drive does not mount

    My 2TB external hard drive does not mount and I cannot get it to.  Have tried turning the hard drive off and then back on.  No response.  Any thoughts as to how I can get it to be recognized?

    You can try doing a SMC reset, if it doesn't work the first time it's totally OK to reset the SMC several times.
    SMC RESET
    Shut down the computer.
    Unplug the computer's power cord and all peripherals.
    Press and hold the power button for 5 seconds.
    Release the power button.
    Attach the computers power cable.
    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.

  • External hard drive does not mount after sleep

    I am using a brand new Seagate 2 TB external hard drive for my backup drive.  More often than not, when the computer goes to sleep, the icon for the drive is gone from the desktop when the computer wakes up.  I have to unplug it from the computer and reconnect it, then it mounts and works fine.  I have it plugged directly into the computer's USB port.  The drive uses USB3.  As far as I can tell, it does not exceed the power requirements of the USB port.  It is the only external hard drive I am using at the moment.
    I should note that the same thing was happening with my last hard drive.  That was a Western Digital 250 GB drive with an independant power source connected by firewire.
    I am running OS 10.6.8 on an Intel circa 2009 iMac.  My external drives worked fine for years, and it seems in the last year or so is when this started happening.

    Another point of note is that both the HD and the keyboard are connected to the iMac through a 7 port USB hub.
    I think this might be the issue. If the iMac is waking back up, it will likely be waking up this HUB, but the HUB might not be re-initialising the connection between OS X and the external drive or the keyboard.
    After waking the iMac, if you unplug the external drive from the HUB, then plug it back in again, does OS X pick it up again? Have you tried plugging the external drive directly into the iMac and then testing what the result is?
    If you read back on what you've said, you pointed out that you have a USB mouse that you use to wake the iMac from sleep. Is this mouse directly connected to the iMac? If so, it surely can't be a coincidence that a directly connected USB device can wake the iMac from sleep, but any USB devices connected to the iMac via a USB HUB cannot.
    I would suggest you test the drive as it is directly connected to the iMac. I would complete the same test with the keyboard too. I think you'll find it's the USB HUB.
    I hope this helps.

  • External Hard drive will not mount on desktop

    I have a 17" Powerbook G4 that has replaced a broken iBook G4. I've been using a Western Digital MyBook Pro Edition as a secondary drive for my multimedia as well as my iTunes Library. It worked fine on the old iBook.
    When I plug it into the Powerbook, using either USB2 or Firewire 800, it will not mount to the desktop. It DOES however appear in the System Profiler as "External HD Button and Lights". The drive is formatted for FAT32 and works fine on my Windows XP desktop machine, so I know the drive functions mechanically. A different hard drive, a Maxtor mounts to the desktop fine using USB2, so it isn't a bus issue.
    This is driving me nuts. I LOVE this computer, but I have WAY more invested in music than the cost of the computer.
    Thanks in advance.

  • External Hard Drive will not mount

    My external hard drive that I been storing all my aperture files on is not mounting to the desktop. I can see the hard drive when I use my disk utility, but it doesn’t show up in the desktop.
    When I purchased the hard drive originally I didn’t format to apple but it worked fine.
    Please help…

    Make sure the drive is powered from from its separate power source, not solely through the FW or USB connection.
    If it is a dual connectivity drive, try connecting from the second method (e.g. if you are using the much preferable FW, try switching to the much-less-good USB).

  • Problems with External Hard drive, will not mount and errors in disk utilit

    i have a powerbook g4 aluminum. i have an external hard drive for it. a simple tech 100gig portable drive, almost brand new. i dont know what happened to it, but one day i was starting my computer up with it attached. it wounldnt fully start up, said "waiting for local disks" so i uplugged the external hard drive. now it wont mount and will only show up in the disk utility of my friends macbook. i tried to verify and repair, and this is the message i got.

    Hi, hjbugs, and welcome to Apple Discussions. Disconnecting the drive while your Powerbook was accessing it probably caused your problem. It may be repairable using DiskWarrior or TechTool Pro, but if you don't have access to one of those and aren't going to buy one, reformatting the drive with Disk Utility may be the only other way to make it usable again. If it contains data you need to recover first (i.e., data that isn't also stored on your internal HD or other storage media), download the free demo version of one of the data recovery utilities mentioned in this thread and use it to see what is recoverable. If the files you need are recoverable, buy the full version of one of the utilities and recover them.

  • External hard drive will not mount nor repair... ='(

    My internal hard drive was failing, so I backed up all of my data onto a 500GB WD Passport external hard drive and ordered a warranty replacement. Yesterday I received the replacement and went to restore my data. I used Carbon Copy Cloner to restore it and after about 45GB, my computer completely froze. I restarted and tried again, this time the same thing happened at the same point. I restarted, but this time it would not boot off of the external HD. I booted off of another external HD and ran "Repair Disk" in Disk Utility. It took forever, but when it finished it said something like I need to backup, erase, and restore. The problem is that I can't access any of my data on the drive!
    Is there any program I can use to repair it? Or is there any way to force it to mount?

    I won't try to answer any of your questions, but I do have a set of my own: How did you initialize that replacement drive? Did you set the partition map scheme to "GUID Partition Table"? Did you format the volume as "Mac OS Extended (Journaled)"?

    You may believe this is Apple's problem but I just like Baltwo have had absolutely no problems with any of my Firewire drives in Lion. So unless you can come up with much stronger evidence to the contrary, I doubt that your feeling are going to carry any weight at all.

  • External Hard Drives will not Mount

    I have a WD & LaCie external hard drives in my iMac G5 they have been working fine until I started using the new Time Machine program. Now the drive show up in disk utility but not on the desktop. Disk utility has been no help in repairing them and in its log states " Invalid content in Journal " .
    How do I get my drives back ?

    I did an archive reinstall of Leopard and I still had my problem, so I schleped it down to the Apple store and for the life of me We could not make it happen, drives shoed up fine and worked fine. I think I have a bad FW port that is intermittant but for now I cannot have them fix something that seems to work...
    I dont thisnk we have the same problem, because when I had my drives not showing up on the desktop, they were not showing up in Disk Utilitiy either.
    Is there data on those drives that you must have? If not I would try reformatting them with Disk Utility ("erase") and see if they reappear. If there is data on them, I would try running a better utility program such as DiskWarrior, I think you can run it on external Disks to rebuild the directory. The problem is that the present version, 4.0 is not compatible with Leopard. The new one is out soon if not already for Leopard. There is no guarantee that that will work, but may be worth a try.

  • LACIE external hard drive will not mount

    I had this problem with Tiger too. I have to turn the LaCie external hard drive on and off 4 or 5 times before it appears on my desktop. This shouldn't be right! Can I do something about this???

    Another Lacie issue (lacie 250 d2) . Similar the others. WHen I installed leopard it asked if this was the drive to use etc and i said yes. Since then it wont work. All attempts to back up have failed. I cant reformat either. Just get beachball when ever I try anything with the disk. Only way to do anything is to remove the FW connection. Tried the drive on another G4 (tiger) and it scanned and reported "disk seems ok" but then any attempt to write to the drive or any other activity is greeted with beachball.'
    Rang the distributor and was told " we are having some issues with lacie and we are losing confidence ... would you like to buy a western digital" !!!

  • External Hard Drive will not mount through USB Hub.

    The Hard Drives are ok. If I plug them directly into my iMac (3 weeks old and update to 10.7.1) they mount fine. But they wont show up if I plug them into my USB Hub that is plugged into my iMac. I have had THREE USB Hubs and all of them have had problems. I have USB flash drive that sometimes shows up and a iPhone that will show up in iTunes when I mount it through the hub.
    Is there a program (in the system or share/freeware) that will force the Mac to scan and mount them?
    thanks - Otto.

    The issue is the EHD's are not getting enough power. Going forward never buy EHD's unless they have their own power supply. I would recommend either connecting directly to the iMac or replacing them with higher quality devices. The EHD's I like to recommend are:
    OWC Mercury Elite Pro series
    LaCie d2 Quadra series
    G-Tech G-DRIVE series
    All are similar in quality and features. Yes they're probably more money that what you paid however they're worth it. I use the LaCie's however I wouldn't hesitate to use the OWC or G-Tech's either.

  • 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.
