HELP! macbook killed my external drive!

I have a maxtor drive plugged into my macbook via usb.
I unplugged the headphones with itunes open and a got a kernal panic. so i held down the power button and turned the computer off.
when i turned it back on, the maxtor wouldn't mount, it says i inserted a disk that was unreadable and it wanted to initialize it!!
how can i ressurect this drive??? are there any disk utilities that will work on the new intel macs???
  Mac OS X (10.4)  

OS X comes with a capable utility, Disk Utility. You'll find it in your Utilities folder. Presently there are no third-party utilities that are known to work properly on Intel Macs. Disk Warrior cannot boot an Intel Mac, but if you boot from an external drive and run Disk Warrior from the external drive it may run. But it's unknown if it will reliably repair and Alsoft has not made any definitive announcements. The same is true of TechTool Pro.

    Once you have the drive connected to your Mac, click System Preferences (gear icon) on the dock
    Click Time Machine
    Click Options
    Be default, the hard drive will be Excluded from backups. Click the drive to highlight it, then click the "-" (minus) button at the bottom of the list to remove the drive from Excluded items.
    The drive will be backed up on the next Time Machine pass
    Everything above assumes that the hard drive has been formatted in Mac OS Extended (Journaled) as Time Machine will only backup drives in that format.

  • Emptying trash isn't freeing up any space on MacBook Pro or external drive. Time Machine is OFF.

    Yesterday, while using Final Cut Pro X, I noticed the program/my computer was starting to run slow--and then I was totally caught off guard by a warning that my startup disk was full. I checked Storage and Finder and both my MacBook Pro and external drive had less than 1gb of space each! I usually use Secure Empty Trash and have no problems...but for my drives to be full, it clearly hasn't been working for a few days, possibly weeks.
    I'm using a MacBook Pro (early 2011) and a LaCie Thunderbolt external drive. I'm running Mavericks (10.9.2)
    I am not using Time Machine. When I look at Storage under About This Mac, my Backups on my MBP and LaCie drive are both at zero KB.
    I read through the forums and tried going into Terminal and entering sudo rm -rf ~/.Trash ...but all that did was free up about 10gb on my external drive (I'd emptied upwards of 90gb from my trash).
    Right now I'm basically stuck with a slow laptop and very little storage space, which has slowed my work to a halt. Does anyone know how to fix this?

  • Help with partitioning an external drive

    I've never done this, so am not sure how it works. I have an external drive (250 gb) that I use with SuperDuper to back up my Mac. Now I have decided I also want to keep a separate iTunes library on this drive. Apparently, so that SuperDuper doesn't erase the new iTunes library, the drive will need to be partitioned.
    So. . . I will use Disk Utility to partition that drive into two and call each section something different? Will each section then look like a different drive (for instance, in SuperDuper)?
    Are there any tricks or tips I should know before running Disk Utility's partition application?
    I have searched the forum for info on this, but most of the people seemed to have at least basic knowledge of how it works, so didn't get much help there. I want to ask before I go and erase the drive.
    Thanks in advance!

    Disk Utility offers following partition schemes:
    GUID -> Intel Mac
    Apple Partition Map (APM) -> PPC Mac
    Master Boot Record (MBR) -> PC
    My apology for referring APM as PPC in my previous post. Native partition scheme (GUID for Intel Mac and APM for PPC Mac) must be used in order to install Mac OS X in the partition as startup disk, it allows booting as well as firmware update. If partition must be shared between Intel Mac and PPC Mac, then only APM scheme can be used since both Mac platforms are able to access APM partition but only PPC Mac can boot from this type of partition.
    Since I have only one Intel Mac and booting from external storage is necessary for maintenance (full defragmentation) and repair (in case when internal drive has crashed), I use only GUID scheme for iMac's internal drive and Firewire external drive. Super Duper is used to mirror exactly internal drive to external drive regularly. The only time I have to perform file transfer between PPC Mac and Intel Mac with external drive was during hardware upgrade as follows:
    iBook G4 -> iMac G5 -> iMac CoreDuo -> iMac Core2Duo
    Thus the decision for partition scheme of external drive depends on whether you have to boot Mac OS X from external drive (no in your case but highly recommeded for emergency plan) and whether sharing of external drive between your PowerBook G4 and iMac CoreDuo is desirable. I assume you will select APM scheme for your purpose since booting Mac OS X from external drive is not required.
    Use of very old Master Boot Record (MBR) scheme will turn the external drive into PC drive completely. Unless this drive must be accessed in Windows environment as conventional PC drive for some PC disk utilities (these old utilities can't work with new GUID scheme), use of this non-native scheme for Mac OS X is not advisable.
    Hopefully above information will help you in partitioning external drive. Since you do not have to preserve content of this external drive, why not go ahead and experiment with new partitions to see whether they serve your purpose ? Disk partitioning without writing zero or any random patterns on whole disk takes only few seconds. But it is a good idea to write zero (shortest time required) across whole disk surface to ensure that bad disk blocks are masked off to prevent future access and possible crash.

  • MacBook Pro + FS100 + external drive....help!

    I am currently in production on an indie film...this weekend we have a location shoot where I will need to download the footage from our FireStore drives onto external drives so we can have a smooth production and not lots of downtime for offloading said footage.
    I have a MacBook that I planned on using for this function (usually we just put it on the Quad-Core after the day of shooting is over) but I only have one fire wire input on my MacBook - I need to have one for the FS drive and one for the external HD.
    Any suggestions?? I'm stumped (or I could just be fried from this long month of production...)

    btw, Shane - your tutorial on importing P2 footage from the card & FireStore saved my butt!! THANK YOU SO MUCH!
    I will check out my externals to see if I can figure it out. I think they do have 2 firewire inputs....I'm not quite sure though how to configure that....Both the computer & FS100 drive would go into the HD? Man, I feel like an idiot - this is unchartered territory for me!!

  • Can't boot my Macbook from an external drive

    Hi there,
    After my internal hard drive failed, I put an older (temporary, and somewhat small -- 100gb) internal hard drive onto my Macbook, and using a time machine used an external drive to recreate the data and OS that were on the internal drive that failed. Part of the reason I did this, rather than just buying a new internal drive, is that I live in Germany and my family is coming to visit in a month with a brand new mac, so I'm hoping to just run everything off this external drive until I get the new computer and can transfer all my data over.
    Anyway, I can't get the computer to boot from the external drive. It has the right partitioning scheme (GUID), my mac is willing to assign it Bootup Status, and when I browse the contents of the external drive, it basically looks fine. The termporary internal drive, incidentally, is running 10.6.7 as well, and using time machine I put my old applications on it, but not my user data. I can boot from that internal drive, but when I try to boot from the external drive I get stuck on the grey screen. Any idea what might be the problem and how I might fix it?  Or a suggestion about how I can run my computer off this external drive until the new mac arrives next month?
    A few technical details:
    My macbook is about 5 years old, and when I check the "about this mac" tab it says it is running 10.6.7 OS, with a 1.83 GHz Intel Core Duo processor and its memory is 2BG 667 MHz DDR2 SDRAM.
    The external hard drive is LaCie, 500gb, firewire 800 cable (and with the option to use a USB port too), which uses the macbook as its power source.
    Thanks for your help and advice.
    Bernie

    Hi,
    Thank you for your time.
    Even if Disk Warrior can help recover/restore my files i think replacing the hard drive is necessary, right ?

  • Need help moving photos to external drive

    Hi, all--here's hoping one or more of you Aperture veterans can help.
    Here's my situation: I'm not new to photography, but I'm new to Aperture. Just bought 3.3 and still getting to know what it can do. I'm an emigre from iPhoto, and one of the reasons I upgraded within Apple is that I was tired of the non-intuitive nature of PS Elements. I like to take pictures, not spend endless time in the dim glow of a screen digging through sub-menus for stuff, and from what I read, Aperture seemed more intuitive.
    But now I've got a seemingly very basic problem that hours of poring over discussion threads and searching through the hundreds of pages of the manual has done little to address with any clarity:
    How do I move (not just copy) older photos in projects to external drives, but in such a way that Aperture still keeps track of them, even when the drives are not connected? (The Aperture marketing I read/viewed clearly said Aperture could do this, and I'm running out of space on my MacBook Pro (15" from about 2008, running Lion) with lots of CF cards piling up.)
    Info that may help:
    -I need to move not just original (imported into iPhoto directly from the camera) photos, but also those I've adjusted in Elements, then re-exported into iPhoto (I would say "and now into Aperture," but as you know, there's no longer an import process b/w iPhoto and Aperture).
    -I shoot mostly RAW.
    -I have no idea whether the pictures are "Referenced" or "Managed" (for space reasons, I have yet to import any files directly into Aperture; all existing photos are from iPhoto, and if I was given an option when I set up Aperture, I don't now recall it).
    -I have external drives with plenty of space to move older pix to (I also have multiple backups, including Time Machine, additional external hard drives, and DVDs)
    Can somebody who knows how to do this safely please explain in clear language how to move photos as projects onto external hard drives so that Aperture keeps track of them via viewable thumbnails, even when the photo files themselves live on a hard drive that is not connected at the time?
    Thanks in advance!

    First things first:
    You can easily check if an image is managed or referenced by ctrl-clicking on an image version and selecting "Locate referenced files...". If Aperture says "No Referenced Files", your originals are managed by Aperture and stored within the library itself, otherwise it should show you the location of the original, and give you some options to verify the references and so on. I don't know which method is used when importing from iPhoto.
    Now, here's something you need to ask yourself:
    Does it make more sense for you to keep the library on your laptop and the originals on an external drive, or does it make more sense to move both the library and the originals to the external drives?
    In the first case, you can open and look at the thumbnails, but there's not a whole lot else you can do with your images when the external drive is off line.
    If you have vast amounts of originals, spread across multiple drives, it might make sense to keep the library on your laptop and connect whichever external drive you need at the time. However, it might also make more sense to split such a huge library into mutiple libraries, stored with their respective originals (which could be either managed or referenced).
    In my case, it makes sense to keep multiple libraries, with managed originals, but your mileage may vary.
    Here's a tip that might help you decide: A small library is quicker to navigate and work with than a huge one, although performance has improved vastly with later versions of Aperture.
    Once you have decided on the appropriate organization, you can start moving things around (after you've created the appropriate backups):
    If your library contains all managed originals already, and you want to move the entire library off to the external drive:Simply drag and drop the library itself (using Finder) to the new location.
    If your library use referenced originals, and you want to keep it that way, or your library manages your originals, and you want to start using referenced originals:
    Select all your images
    Click on the File menu and select Relocate Originals...
    Locate the destination for your originals, and pay special attention to the "Subfolder Format" and "Name Format". I'd suggest choosing "Project Name" and "Original File Name" for the two.
    Click on Relocate Originals, and twiddle your thumbs while Aperure moves all your originals to the new location.
    If your library uses referenced originals, and you wish to let your library manage the originals:
    Select all your images
    Click on the File menu and select Consolidate Originals...
    Decide if you want to Copy or Move the originals into the library. If you're running out of space, it might be best to Move.
    Click Ok, and wait for the operation to complete.
    (Optional) If you wish to move your entire library to the external drive, drag and drop the library to the new location.
    I hope that answers your question.

  • UPS Energy Saver on MacBook Pro for External Drives

    A search here has shown this topic come up before -- such as at https://discussions.apple.com/message/1886738#1886738 and https://discussions.apple.com/message/8162836#8162836 -- but I can't find a resolution, so I'm bringing it up again.
    I have multiple FW drives connected to my MacBook Pro. The MBP is connected to an APC Back-UPS RS 1200. OSX does not make the UPS Energy Saver autoshutdown preferences available on the MBP, the reasoning being that a laptop shouldn't need UPS autoshutdown because it has its own battery which is likely to run for far longer than the UPS would.
    That's all well and good for the MBP itself, but it doesn't account for the multiple FW drives which are attached to it for backups and other purposes. In the event of a power outage, without UPS autoshutdown, the UPS will run down, and the drives will abruptly power off, exposing them to potential data loss and damage.
    It's also not a solution to suggest that I manually power things down once there's a power outage, because the power can go out while I'm away for more than the few minutes of UPS battery back up time. The only real solution is to have UPS autoshutdown available on all portable machines. Unless and until Apple offers a (surely very simple) OS update to make that happen, I'm still interested in a solution.
    APC's own software for autoshutdown stopped being updated long ago, so there is no version compatible with Snow Leopard.
    The only potential solution I've found so far is http://www.apcupsd.org/ -- but its documentation is overwhelming and it appears that it may need other supporting software, a fair amount of Terminal usage, etc., all making it not very user-friendly for the very simple usage I'd want to make of it.
    Does anyone know of any other solutions, software that can run on a MBP to add UPS autoshutdown functionality?
    Re: Apcups, is anyone using it successfully on a MBP? If so, does anyone know if the version listed here -- http://mac.softpedia.com/get/System-Utilities/Apcupsd.shtml -- is a simple application that I can easily install and configure like regular Mac apps? If yes, then I'll likely be very happy with no need for the following question. If no, can anyone provide simple instructions to set up Apcupsd to do what I want?

    "You are not doing anything on the computer so no files should be writing to the drives."
    Big assumption there. With today's notebooks so capable of acting as desktop substitutes, they are often left running unattended to complete demanding tasks overnight or while the user does other things.
    To be able to suspend such activities and gracefully power down an external drive or drives in the event of a power outage, the Mac would have to have instructions from each third-party application or process that is running about how to interrupt its activity safely and without jeopardizing the integrity of whatever hard disk directories are in use. Then it would need to unmount the drive(s) and, if they were bus-powered drives, turn off the power to each of them at the port to which it was connected. I bet it would be possible for all app developers to write such instructions into their apps' code, but where's the incentive for them to do so? This isn't a feature that most users would gladly pay extra for, I suspect, and the cost of adding it to apps that don't have it now and testing it for reliability and proper function under all conceivable circumstances would not be trivial.
    If the drive(s) were AC-powered, the computer wouldn't be able to power them down itself -- the UPS would have to do that, or simply leave them on and power them until its battery was depleted or the AC was restored. It wouldn't matter which happened as far as the drives and their contents were concerned, because once the computer stopped using them, powering them off would be safe at any time.

  • Windows XP Pro on MacBook Pro with 'external drive'!?

    I don't want to load Windows XP Pro on the MBP ... it will take up too much space - I'm running Final Cut Studio and Logic Audio.
    Can I put Windows XP Pro on a SEPARATE DRIVE, along with the few apps I want to use in Windows ... and then BOOT from that drive when I want to work in Windows?
    And would there be something specific I have to watch out for?
    Is there a good article somewhere about running Windows on the Mac Intel? That would help my technical guy create the bootable Windows\Mac Intel version external drive?
    Thank you,
    Ben

    Thank you Blue,
    I'm awaiting my new Final Cut Pro Studio Universal disks, and then my Logic Audio 'Universal' disk ... I don't think I'm going to have a lot of room to play with.
    I'm already eyeing the 120 gig drive.
    But, actually, I'm not sure I want to have Windows in any way connected to this computer. The idea makes me nervous.

  • Time Machine 1 iMac, 1 Macbook and one external drive

    This must be a very simple question as I cannot find anyone else that seems to have this problem.
    I have a Macbook that is just a few months old and a very new iMac each running Leopard. I have an external drive connected via Firewire 800 to the iMac. I have shared the drive on the iMac so the Macbook can access it. I mount the drive under Devices in Finder on the Macbook. In Time Machine preferences on the Macbook I select the drive to be used by Time Machine. When I do a Back up Now I get the Preparing message for a few seconds and then get a Failed message. The status is: 'Latest Backup: Delayed'.
    Oh and I have just clicked on the red I next to the Failed message and am told:
    Time Machine Error The backup volume could not be mounted.
    Is Time Machine an idea before its time (I speak as an old Windows user that is used to stuff being released before it is stable - and I am beginning to wonder if I should have stuck with the devil I know)

    See this article: Mac OS X 10.5- Time Machine - "The backup volume could not be mounted" alert.

  • Need help connecting to my external drive

    I have an EXTERNAL drive connected to my iMac G5 running 10.4.11. I can not access this drive via the network from my MacBook running 10.5.7. I've check file sharing on both machines prefs.
    I can connect to the iMac's HD from my MacBook via my network, but just can't seem to locate the EXTERNAL thats connected to it. I downloaded Sharepoint and still can not get my remote computer to find the external drive.

    Great news, thanks!
    Leopard will be the last OS for PPC Macs, so eventually you'll have to, but I'm thinking Tiger should be compatible for another year or two, but in a couple of years Leopard may no longer be sold by Apple, I'm seeing Tiger Install discs go for $200+ nowadays.

  • Need help moving masters to external drive

    Drag images from internal drive to external...
    Relocate Masters...
    Locate Referenced Files......
    I realize these options are available, but I'm wondering which way to do this. Out of 160 GB of images about 1/2 of them are imported into Aperture while the remaining 1/2 are on the Mac but not in Aperture. All images are on my internal drive and I use Aperture as referenced masters, not managed. I need to make space on my internal drive and need to move all images (those already imported and those not yet imported) to an external. Given my current set up (1/2 imported 1/2 not), which option is best for a clean move to the external w/o messing up Aperture?
    Thank you,
    Jerry

    Jerry -- sorry, this thread slipped by.  I haven't had the time recently to be attentive.

    So, I still need a little help with this. If I have this folder structure on my internal drive and 1/2 of those images are imported into Aperture (but referenced), and I use the "Relocate" feature, how will they be moved? Will it take the folders to the external or just the images, leaving the folders on the internal drive?
    I'm afraid to experiment in case it messes things up. Any help is greatly appreciated.
    1.  Don't be afraid to experiment -- set up a practice Library and use it to experiment.  That's how all of us learned what we know.
    2.  Your situation is a little peculiar, and I'm going to recommend something I wouldn't otherwise.  First, backup your system and confirm your backup.  Then go ahead and use Finder to copy all the Finder folders and files in question, intact, to a new drive.  Then delete the ones on your system drive.  Then open Aperture and run "File➞Locate Referenced Files" to re-attach your Aperture Images to your moved files.  You may have to run "File➞Locate Referenced Files" more than once (but most likely not) in order to end up with no Images that have missing Originals.  (If you need to, search for posts on the board about using this command.)
    At that point, you have done what you set out to do: move all of your photo files to an external drive while retaining the connection between those that are Aperture Originals and their corresponding Images in Aperture.
    But you haven't addressed the very good point brought up by bjurasz, which is that you are going out of your way to maintain competing databases.  Aperture is a database of your Images.  It has _outstanding_ storage and retrieval capabilities.  Finder is a database of your files.  It doesn't do a tenth the job Aperture does.  Finder is a file manager.  Aperture is an image manager (that does good file management).  Aperture has _terrific_ tools for helping you instantly retrieve _any_ subset of your Images (e.g.: family, spouse, dog, students from 2010, science students from 2010, vacation photos, vacation photos w. spouse, etc.).  The key to this is simply tagging your Images (e.g.: grayscale 2010 vacation photos w. spouse and dog) so that you can retrieve them as needed.  Importantly, you are not confined to a flat folder structure and whatever information you can stuff into the file name, as you are with Finder.  (Yes, more or less -- Finder is actually much more sophisticated than many realize or use.)
    I suggest moving more fully into Aperture, learning what tags are available and deciding how to use them, designing an Aperture Library structure that meets your needs, and transitioning your Finder collection of photo files to an Aperture database of Images.
    Ask more questions -- might be best to start new threads as they come up.

  • MacBook Air USB external drive power source

    I have a LaCie 250GB USB external drive on my MacBook Air and the computer is not being able to power the drive without me connecting the hard drive to an external power source. when the drive was had about 80GB of data it would do it, now that the drive has about 180GB of data, it does not work. Can anybody recommend a solution or an external drive that can hold at least 250GB that can be powered by the MacBook Air without need for external power source?

    I have the same time of problem. Although, it's mentioned a using a self powered hub. However, I find this did not work. Apple states that the single usb port on the MBA is high powered to give the ext. super drive they sell the power it needs to connect to the MBA. What I have noticed is no matter which USB self powered hub I use I get the same results. The MBA reports that one or more devices is drawing too much power. Although, the powered hub is supposed to provide power to those devices that require power over USB. I should also mention, all I am connecting are two USB devices. 1 ext. Verbatim 500 Gig Drive. and my iPhone. Since the MBA has only 120 gig drive I had to move all of my movies etc. to the Ext. 500 now if I want to sync my phone or move a movie to the phone I get the errors.
