Formatting a Thunderbolt drive

I'm trying to set up a Lacie Thunderbolt drive as my recording drive from a Macbook Pro. At present the 4TB drive is configured as Raid 0, Extended Journaled. But I see Apple advising that a recording drive should be Unjournaled. Yet when I try to select 'Unjournaled' from the file menu for this drive in Disk Utility, that option is greyed out.
Any views on where I should go?

Since I pretty much know.. that you know what you're talking about.. I won't press the point.
However, I agree that journaling is a good idea on a system drive and in fact it may help preserve disk integrity resulting from a system crash I maintain that it offers absolutely no benefit to a drive used exclusively for audio.
And, if you haven't tested it...  try recording 12 tracks (approx 7-10 minutes worth) to a journaled drive, next, try the same test to the same drive formatted with journaling off.

  • I've become locked out of my time machine back up--how do I override or re-format the thunderbolt drive?

    How do I re-format thunderbolt drive used as time machine backup?  Password is not working and I just need to do a new back up and am willing to reformat the drive but can't get past password dialog box.

    Hi Oneontarider,
    To reformat your external hard drive you would erase it using Disk Utility. See this article for directions -

  • Can I use bootcamp and install Windows 7 on an external Thunderbolt drive

    Hello,
    I want to know if it is possible to install windows 7 on a thunderbolt external hard. I have a limited space on my harddrive and want to have windows 7 operate and store data on the thunderbolt drive.
    Anyone know if this works or if its possible.
    Thanks

    i use a thunderbolt ssd for my boot disc and it appears that bootcamp appears to start ok. in disk utility i can partition the drive successfully so i would be really interested if this would work. personally i cant see any problems.
    are you thinking about formating the drive and installing windows without bootcamp? that will definately not work!
    however with bootcamp you stand a very good chance of achieving your wish. please keep us posted if you decide to do this.
    i know of one way that can absolutely do it, but it means installing osx on your ext. first. i have vmware on my ext. running win 8.1 works seamlessly.
    i run bootcamp from my internal hdd with win 7.

  • Thunderbolt drives on my Apple 27" TB Display absent

    I'm running Boot Camp Win8.1 with my MPL13 using the Apple "27" Thunderbolt Display but my Thunderbolt drives connected to the Display will not connect.
    Any ideas how to?

    How are these TB drives formatted? You can only see HFS+ disks on the Windows side if Bootcamp drivers are installed. CoreStorage (or FileVault2) volumes cannot be seen.

  • Red Light on Promise Pegasus R4v Thunderbolt drive

    I was told by Promise to use the promise utility to fix this but I can't install the software downloaded from their site because it says Apple doesn't support it. It didn't come with a disk. Before I go and load all my data on this thing I want to know that drive is working right and a red light is not a good start, and knowing I can't use their software is even more troubling.

    I had this problem with an external G-Drive thunderbolt which I bought in August.  Started getting this message and replaced the drive at the Apple store under the 15 day return, and was very careful about not accidentally unplugging the replacement drive.  No problems until today. Yesterday, I accidentally unplugged the drive.  Now, after rebooting I am getting the message every 5-20 minutes.  So it appears there is some kind of reliability issue related to the drive state caused by a hot eject.  The vendor website the states the drive can be "damaged" by ejecting the drive without properly dismounting it through the finder.  Hopefully the problem is in a magnetic component that can be reformatted.
    Looking around I am seeing 5 or 6 threads that have come up in the last couple of months related to external thunderbolt drives.  This is obviously an issue that could sneak through QA.  So it appears to be a generic issue.  Maybe Yosemite would also fix it, but I'll start with a reformat.
    After I format this thing I will let you know what happens.

  • Mountain Lion Time Machine Encryption Fails with External Thunderbolt Drive

    I have a Buffalo 1TB MiniStation external Thunderbolt/USB3.0 Drive that I am trying to select from Time Machine with Encryption on. It fails. Further, when attempting to encrypt the drive from Disk Utility, it succeeds however when mounting the disk displays "Unusable Disk" after the password prompt and can only be mounted by re-formatting with encryprion turned off.
    Selecting repair disk also does not work as the drive fails to mount.
    This can be duplicated using the either connection (Thunderbolt or USB).
    I called the manufacturer of the drive and they state it is "Apple's problem".
    Any help here?

    Unlikely. If encryption works for other USB3/Thunderbolt drives, then it is definitely Buffalo's problem. At this time, there aren't many such drives so it is hard to say. Buffalo's Time Machine customers don't seem to be happy with Buffalo's support: http://forums.buffalotech.com/t5/Storage/bd-p/0101

  • Lacie Thunderbolt drive able to be encrypted?

    Hi, I have got a 2TB Lacie Thunderbolt drive (great little thing!) But since I use it for large documents that I need when on the road I usually do format the external drives encrypted, Since sensitive data is on there and in hotels always is a risk that something gets stolen.I used PGP before Lion and was happy when I was able to retire it with Lion. My question is: I don't see a possibility to encrypt the raid here, do I miss something?
    Thanks

    Create a disc image file using a Format of "sparsebundle." This type of image file will expand as needed. For simpliciy you can even select the folder containing all your sensitive files and create a new disc image from the entire folder. Disk Utility will provide a range of options including the type of encryption desired.

  • How to format an external drive for mac AND pc use

    i want to format my external drive so i can use it on my mac and on pc's as well. i've gathered that the MS-DOS format is the way to go. my question is this: would this create any problems for my mac then?
    can i partion one part for ms-dos and part for macos extended?
    cheers
    -j-

    MS-DOS format (or FAT32) will be fine for both Mac and PC. However there is a 4GB file size limit with FAT32.
    You could use a dual partition, however the HFS+ partition would not be readable by the PC unless you installed the third party MacDrive.
    Look at this page for more information on a dual partition drive for Mac and Windows.

  • Boot windows 7 from an external ssd/thunderbolt drive

    I have an iMac 27", Mid 2011, 3.4 Ghz i7 Quad core with a 2TB internal HDD OSX 10.7.5 and a MacBook Air 2014 - Mavericks.
    I want to create either a 64Gb USB 3 Flash stick or, if necessary (as I would have to buy it) an external thunderbolt drive to run Windows 7 rather than partition my internal hard drive on either computer.
    Basically I want to create a totaly portable windows boot drive to run windows 7 and some software I need for work (I just really hate using my slow, POS, work laptop) to run on either mac as I need it
    Is this possible?
    Will bootcamp recognise either of these types of drives to switch between OSX and Windows - I know USB drives are not recognised?
    Can someone point me in the right direction on idiot proof instructions on how to create this?
    Thanks for your help in advance

    That is true, and may indeed work. You'll likely know during the installation of Windows if it allows you to select a partition on an external drive to install it to.
    I'd be very interested in hearing your results.

  • Cinema Display hookup via a Thunderbolt drive

    I believe it's possible to run a Cinema Display from my MBP via a Thunderbolt drive, going from the MBp to the TB and then, via a Mini-display to DVI cable, into the display.
    I've hooked it up this way with the display also plugged into its power supply and usb'd into the MBP: nothing
    When I click 'Find displays' I hear activity in the thunderbolt drive (a Lacie 2big) but that's about it. Nothing shows on the Cinema Display.
    I'm doing somethin wrong probably, a familiar scene.
    Anyone done this successfully?
    (I'm running 10.7.3)

    A dvi display with a resolution greater than 1920 x 1200 requires a dual link dvi adapter.  I assume you are using a single link dvi adaper (or cable).

  • Disk utility reports "Device could not be opened" - error when trying to format a new drive in a Mac Pro 1,1

    MacPro 1,1 Quadcore 3 GHz (2006 "Woodcrest")
    32 GB RAM
    ATI Radeon HD 5770
    OS X 10.7.5 Lion
    I have encountered the following behavior when trying to format a new drive with disk utility. This description has also been send via the Mac Pro feedback as a bug report to Apple.
    On searching the web and forums with this particular error message and behaviour I could not find any usful results. So maybe the following description may be helpful for some users.
    Best regards.
    1. Drive Bay 1 contains the original 250 GB Startupdisk. It works without errors.
    2. Drive Bays 3 and 4 contain each a WD Caviar Black 2 TB SATA 3 HDD. They work without errors.
    3. I have purchased a third WD Caviar Black 2 TB HDD.
    4. In Drive Bay 2 there has been a Seagate 750 GB HDD, which worked in conjunction with all the other drives without error.
    5. I exchanged the Seagate HDD in Drive Bay 2 with the new WD Caviar Black 2 TB HDD.
    6. On starting the system, it will report to initialize the new drive.
    7. On trying to initialize the new drive with disk utility it reports the error [translated from German] "Erasing of the volume has failed. The device could not be opened."
    8. I thought that the drive is faulty. Thus I created an RMA-Case at WD. They exchanged the drive without problems.
    9. On getting the exchanged WD Caviar Black 2 TB drive I put it in Drive Bay 2 as before.
    10. On trying to erase and format the exchange drive I got the same error message "Drive could not be opened."
    10.1 On selecting the physical drive in the devices list, disk utility reports all information in the bottom area of its window as usual, e. g. hard disk description, connection bus, type and place, capacity, write status, SMART-status, partition scheme.
    10.1 On leaving that drive selected in the devices list and clicking the info-button, disk utility will also report additional information as usual, e. g. Name, Type, partition scheme, media-identification, media name, media type, device tree, … , number of relocated sectors, etc.. All this information appears to be valid, as can be compared to the other devices information inside the other Drive Bays. Also the disk numbering scheme appears to be standard - 4 HDDs give the numbering disk0, disk1, disk2, disk3.
    10.2 From that information I conclude that the SATA-bus and connectors electrically work properly, the drive has spun up and can be accessed by the system normally.
    11. I powered down the computer, took out the HDDs from Drive Bays 3 and 4 and put the caddy with the new exchange drive in Drive Bay 4 [Maybe, I could have also just left it alone in Drive Bay 2, or 3].
    12. After powering on the system, disk utility will quick format the exchange drive without any error message. Also, when erasing again by selecting the option to write zeros to the drive, disk utility will finish without error.
    13. After disk utility finished formatting, I put back the original drives into Drive Bay 3 and 4 and put the now newly formatted drive back into Drive Bay 2.
    14. After switching on the computer the system start and login proceeds without any error message. All drives appear as expected on the desktop.

    If anyone is reading this still looking for what caused the issue and how to fix it here is what I discovered.
    The antivirus program our company uses, Bitdefender Antivirus Plus, was causing some of the PDF files not to open. After troubleshooting the different modules and settings the culprit was..
    Scan SSL in Privacy Control Settings. Turning it OFF solved the problem and all the PDF files that previously would not open now open just fine. This issue has been sent to Bitdefender for them to review. If you use a different antivirus program and are having this issue try locating the Scan SSL setting and see if turning it off solves the problem.

  • Can I create a windows 7 partition on a 1TB thunderbolt drive to use with my Macbook Pro?

    I have a new Retina Display Macbook Pro with a 250gb SSD Drive that is quickly running out of space. My work recently gave me a new project to do some programming that can only be done in a Windows environment. With the price of Thunderbolt drives coming down I was wondering if I could build and boot to a Windows 7 partition on the Thunderbolt Drive and use that when I need to run Windows applications. Also what would the speeds be like? Would I be able to run apps like Photoshop and Illustrator? Also if that works would I be capable of creating a partition for my kids to install their games on?

    Redgoat,
    (1) USB 3.0/2.0 Drive will boot a windows 7 installation,  (hold down option when you boot)
    * I am not yet awake if thunderbolt drives will be detected by the macbook pro for booting purposes.  I cannot see why not
    (2) if you are concerned about speeds you can purchase a SSD USB 3.0 drive but a standard hard drive is quite reasonable with a USB 3.0 connection
    and lastly MacBook Pro Retina are mean gaming notebooks and bootcamp is the best way to do windows gaming on it.

  • MacBook Pro crashed while deleting old backups off partitioned external hard drive. Now only recognizes windows formatted half of drive. Can the Apple side be saved?

    MacBook Pro 15-inch, Mid 2010
    Processor  2.66 GHz Intel Core i7
    Memory  8 GB 1067 MHz DDR3
    Graphics  NVIDIA GeForce GT 330M 512 MB
    Software  OS X 10.9.5 (13F34)
    I have an external hard drive:
    2 TB Seagate Backup+Desk Media
    Partitioned:
    1TB - Windows NTFS
    1TB - Mac (sorry I can't remember the formatting, whatever Mavricks asked me to use...)
    What happened:
    I was erasing 3 old backups from the Apple partition and my laptop crashed part way through emptying the trash. (it has done this many times before, where parts of the screen are frozen in square blocks displaced all over the screen. Screenshot not possible unless I use a separate camera).
    When I force restarted my computer (holding down the power button) neither side of the drive was accessible. After running the Disk Utility and Verifying and Repairing the Disk Permissions and the Disk Itself (for the Windows side) I was able to access the Windows partition. However, upon attempting to do so with the Mac partition it tells me that it cannot be repaired. I have found many forums discussing SIMILAR situations but none with the same and here is why:
    Up until this happening I could access ONLY the Windows partition when the drive was connected to either my Apple laptop in Bootcamp Windows 7 or my HP laptop in Vista, while my MacBook could access both sides of the drive. HOWEVER, after this crash, BOTH my Windows 7 and Vista can access both sides of the drive (so My files are still all there and accessible) but my MacBook Pro swears that the Apple partition is doomed.
    Since the Apple side of my laptop is my primary workhorse I really want to figure out how to fix my drive.
    So Questions:
    1. Anything else I can provide to the experts out there to help me get this fixed?
    2. Can I custom fix this via accessing the drive on either of the Windows systems?
    3. Why would it suddenly show up in Windows when it became unaccessible to Mac?
    Thanks All!

    UPDATE:
    It has been maybe a month since this happened.
    After I made this post and was checking emails, walking away from computer, and then came back my Mac partition of the External Drive has shown up on the Desktop...
    So, in the ever immortal way of asking the tech to come check the issue and the issue resolving itself, perhaps I should posted on the forum sooner...
    NOTE: The disk still shows up as unusable in the Disk Utility and it appears that the files are read only (cannot make a new folder on this side of the external drive)
    I still consider this a volatile issue because I do not want to lose the files on this half of the partition and I have not gotten a replacement drive yet (too much data to move to my computer and then format the current drive)
