I have a USB hard drive how to change read wright permissions

I have a USB HP Personal Media Drive I had used it with Windows XP but now want to use it with my MAC.
I have tryed to right click on  with finder and went to Get Info but it does not show me the lock or allow me to unlock it.
Can someone help me with this problem?
Also is there a site kinda like Microsoft's Tech Net for Mac or it's OS?
Sorry I am new with Mac.

I'm not familiar with the HP Personal Media Drive, but if it is a portable hard drive or flash memory drive, and it was previously used with Windows XP, it is probably formatted as NTFS. Mac OS X can read NTFS volumes, but it will not write on them (which includes erasing or renming files or folders).
If the drive contains NOTHING that you care about and you plan to use it ONLY with your Mac in the future, you can use Disk Utility to reformat it as a Mac drive.
If you will want to use this drive on both Mac(s) and Windows computers in the future, you can use third-party software such as Paragon NTFS for Mac on the Mac(s) to allow them to write NTFS.
There are other solutions for other usage patterns. How do you plan to use it?

  • I have an external hard drive but it is read only on my macbook.

    I have an external hard drive but it is read only on my macbook. I have tried my friends which works on his macbook but this is also read only on mine. Do I need to change any settings?

    Here's my lo-tech solution (if you have Parallels) to this frustrating problem:
    Eject your hard drive.
    Unplug (USB) your hard drive from the MAC .
    Start Parallels.
    When Windows has started, plug your drive back into the MAC.
    You should get a little screen asking if you want the drive to be utilized by MAC or Windows. Select Windows.
    Use Windows to copy your files over to the hard drive.
    This is less than ideal and not a long-term solution, but I was afraid of attempting any reformatting since I have many files on my hard drive. 
    Just remember that Windows has to be running first, before you plug in your hard drive.

  • Time Capsule/usb hard drive- How to get Time Machine to back it up

    I installed Time Machine with no problems. A 1 TB LaCie hard drive is attached by usb cable to the TC. The LaCie is seen by finder and I can open, edit and save files to it and so can the Macbook Pro on my network.
    Time Machine backed up my internal hard drive on my Mac just fine, but Time Machine refuses to see the external Lacie drive so it cannot back it up.
    Here is the situation:
    1. If I go to Time machine preferences and click Options there are no volumes or folders listed as Do Not Back Up. nothing is there.
    2. If I click Change Disk the name I gave my Time Capsule is listed as it should be but the LaCie drive is listed also as if it were possible for me to back up to that also. The LaCie's name is there with the name of the Time Capsule in parenthesis. Isn't that odd?
    3. When I select the LaCie icon on my desktop and select Get Info in the Sharing & Permissions section it says, "You have custom access" below it says
    Name Privilege
    (unknown) Read & Write
    everyone No Access
    I am new to Mac in general and this permission and sharing thing is still a bit mysterious to me so I don't know if these sharing & permission settings are usual or weird and could be contributing to why the back up of the LaCie drive is not happening.
    This is the final hurdle I have in absolutely convincing my small but vocal office that switching to Macs all around was a great idea.
    Any help would be appreciated.

    This is a really odd answer.
    I have Time Capsule, I add an external drive to it and you say that to back up THAT disk on Time Capsule I need other programs/solutions? This is really a stupid thing.
    1 TB of storage space just for local files right now that on every wireless product you can add an external disk?
    In other words with Apple products I can have all my laptopsappleTvdesktops all wirelessly connected but I can't use Time Capsule to back up datas if disks are not locally attached? With Airport Extreme/Time Capsule I can share datas (music, pictures, my digital life files) with my family computers but if I do this I can't back up these files.
    And just to know how many do I have to spend on other Apple devices, what are these "other solutions" to back up network drives? A server?

  • Using Airport Time Capsule with an external usb hard drive - how to connect

    I have 2TB Airport Time capsule which is connected to my iMac by an ethernet cable and which I use for T.Machine backups - No problems here.
    I have an old MacBook Pro running 10.6.8  and which is also connected to my T/C via wi-fi - again no problems.
    But I understand I can use an external hard drive via usb cable connected via a powered hub, to the T/Capsule and which I wish to do certain backups from my MBP (I have no wish to update the MBP as it runs certain apps no longer available on the iMac (10.9.2)
    Now the problem I have is trying to set it up,  the MBP has Airport Utility 5.6.1 and I can’t continue as it says I need a newer version. As I see it,  the newer version doesn’t work on the MBP only  the iMac.
    A catch 22 situation. If I continue and and go to “manual setup” then try  update, all I get is “correct the problem before updating”  (Allow setup over the internet using Bonjour).
    Anyone have any ideas or images that I can view to try and get things going?
    I should add that I wish to use my external hard drive not as a time machine backup but only for certain items using say, Super Duper, but am unable to get the disk to mount on the MBP
    Alan

    I still can't use it the way I was hoping because it then becomes a T/M back-up disk and not a normal usb/firewire disc.
    You are first mounting the drive on the desktop, correct?
    Not sure what you mean here.
    You can drag/drop files normally or copy/paste files to the drive icon on the desktop, just as you would a normal drive that is displayed on the desktop.
    Or, double click the drive icon on the desktop and drag/drop files into the open window there.
    Tell us the steps that you are using to mount the drive on the desktop. What happens after each step?

  • USB hard drive is set to read only?

    I'm am very new to Mac (my first one). I plug my USB Seagate drive into the Mac and it reads it fine, but says everything is read only. How do i set it up to allow the Mac to modify the files? Does the hard drive have to be reformatted to a Mac OS and/or is it possible to use the same hard drive on the Mac and PC. I have windows XP Pro SP3 installed using VM Fusion as well.
    I have done a lot of video editing Windows based and very rarely moved the files to my PC hard drive. I have to assume you can do the same with Mac, however I have been able to figure out how to do this in iMovie 2009.
    Thanks in advance,

    BRDVPRA,
    Your external drive is undoubtedly formatted as NTFS. As you already know, your Mac can read this format, but it cannot write to it. There are some third-party shareware applications that will allow your Mac to write to the NTFS volume; search for these on versiontracker.com, if you want to give this a try.
    The native Mac format is HFS+ (Mac OS Extended), which cannot be read natively by Windows. Again, there are third-party solutions for this (specifically, a Windows app called "MacDrive," also available on versiontracker.com).
    The only format that will allow reading and writing from both OS X and Windows is the FAT-32 format (called MS-DOS in Disk Utility). This format is older, and less compatible with modern file formats. For example, it will not support files larger than 4 GBs.
    The question that needs answering is whether or not you will using this drive cross-platform, or whether it will be dedicated solely to OS X. If the former, you'll need to use either the FAT-32 format or some third-party solution. If this drive will only be accessed from OS X in the future, you should copy the data, format it as HFS+ (Mac OS Extended), then return the data to it.

  • Locked Hard Drive / Can't Change Privileges or Permissions!

    My non-bootup internal hard drive (a RAID array) is locked. I don't know how it happened for sure, but I can't view any of my files or change any of the disk's privileges or permissions.
    Disk utility can't un-mount the disk, but says in the "Disk Check" that everything is okay. The option to repair permissions in Disk Utility is grayed out because OS X is not installed on this volume.
    I have tried using terminal to CHOWN and CHMOD the volume, but for both commands it says "Operation not permitted." When I CMD-Click the mounted drive, this appears in the info pane:
    Sharing & Permissions:
    Name Privilege
    (Me) Custom
    admin Custom
    (Me) Custom
    admin Custom
    everyone Custom
    I can't change any of the "custom" settings, whether I unlock the padlock or not. All I can change is "Ignore ownership," which does nothing to help...
    I already archived my OS and re-installed 10.5, then upgraded to 10.5.7 and still no luck. I'M TOTALLY STUMPED! Any ideas?

    Okay, it looks like I've solved the problem. After LOTS of searching, I found a discussion that led to the solution... I first ran this command in terminal:
    ls -alO /Volumes
    This command revealed that the "user immutable flag" was set (the text "uchg" appeared with the problematic drive) and permissions looked odd. The following commands fixed both problems:
    chflags nouchg '/Volumes/<drive name>'
    sudo chmod 1775 '/Volumes/<drive name>'

  • How do I view a file from a usb hard drive connected to my airport extreme base station on my ipad 2?

    Hi,
    I just purchased the airport extreme base station.  I have a usb hard drive connected to the base station.  Is it possible to view this hard drive on my ipad 2?  I have been unable to do it.  Any help would be appreciated.

    You can't, not natively. An app like FileBrowser:

    may make this possible, though.

  • Can't see contents of USB hard drive connected to Time Capsule

    Hi. I have a USB hard drive connected to my Time Capsule (which I just got today). I just want to use it as a shared drive, so that the users in my home can use it to access common files (media files, stuff like that).
    The TC's set up is to enable file sharing with accounts. AirPort Disk Guest Access is not allowed.
    When I authenticate as a user via Finder I can see the disk, see that disk space has been used, but can't see the contents. I'm guessing this is because the files that are actually on there belong to some other user.
    Is my guess right? Any suggestions as to how we can all use it as a transfer drive?
    Col

    Fixed it. I connected the USB drive directly to my computer, and dragged the folder into the 'Shared' folder, which Time Capsule had created. The original folder is now visible, which is what I wanted!

  • Where did my USB hard drive that's attached to my Airport Extreme router go

    I have a USB hard drive attached to my Airport Extreme. I upgraded to OS X.5 and the drive disappeared. If I reboot to OS X.4.10 the drive reappears.
    Does Leopard recognize USB drives connected to Airport routers? How can I get Leopard to recognize this drive?

    Hello.
    When you setup up your Airport you give a name and password to the base station. The base station name will show up in a Finder Window. My Finder window shows it between Devices and Places in an item called Shared.
    When you click in your base station name it will refresh the window content and show a folder with the name of your HD connected to the Base Station. On the top part of the window you will see a dark gray bar and the status +*Connected as: Guest*+ and a button Connect  As... . Click this button and select *Registered User* and *type your password* for the Base Station. If you wish you can select the *Remember this password in my keychain*. Now click Connect. You will see that the status in the dark gray bar shows +*Connected as: <your user name>*+.
    Now remember that this HD is not a normal HD to Leopard, it is a Network HD, so it wisely shows it in the Shared item.
    Now Apple understands that in the past this Network HD was shown to users as a Normal HD on the Desktop and this could generate some confusion, so they left a way for us to see it as in Tiger.
    Click on the Desktop and you will the Finder menu bar, select Finder>Preferences and click on the item +*Connected servers*+ in the Show this items on the Desktop. This will do the trick.

  • USB hard drive not detected on reboot

    I am running Windows 7 Ulitmate 64-bit on my 2011 15" Macbook Pro. I have a USB Hard Drive (WD My Passport SE - USB 3.0/2.0 - 1 TB).
    The hard drive is formatted for HFS+ and I am running Mac Drive 8 to detect it in Windows.
    For some reason when I reboot (in Windows), the hard drive won't be there until I unplug it and plug it back in.
    This is really annoying! Can anybody help me? I'm pretty good with things like this but I can't think of any reason this shouldn't be working right.

    I am having the exact same problem. WD 1TB Passport. USB 3.0 drive. Running on Windows 7 Pro 64 via Bootcamp.
    My 1TB Passport is formatted with FAT32 and works with Windows and Mac OS.
    I was getting the same problem when I was running Windows XP Pro on the same MacBook Pro. I was hoping the upgrade to Windows 7 would remidy the issue but it did not.
    The drive light is on in a steady state when I boot and I have the same symptoms as reported by everyone else above.
    In my research, I am leaning towards thinking that it is a power issue related to the cable used to connect the USB 3.0 Drive or something to do with the USB driver for Bootcamp, but researching the WD site suggests it's a power issue, not a faulty or failing drive.
    I have a 500GB WD Passport USB 2.0 also attached to my computer, also running FAT32 and it starts up no problem. It's just the USB 3.0 drive that is having this issue.
    Also worth noting; the drive is detected properly when I boot in Mac OS X. It's only the Windows side I have to unplug and plug back in to access the drive.

  • TM on 2 differnt usb hard drives

    I thought I had come up with a great back up plan:
    1) I have one usb hard drive at work where I run TM every hour.
    2) Once a week take my computer home, connect it to another usb hard drive and change TM preferences to run on that disk.
    3) When I get back to work, I change my TM preferences back to the original usb hard drive.
    4) Expected result: I then have to separate usb hard drives with back ups of my computer, one which have been run every hour and one at home which have been run every week.
    Now I realized that every time I change the TM preferences to run on another usb disk TM will start from scratch and do a completely new TM back up. This means that I can not restore any old files with TM.
    Have I misunderstood something? What should I change to get the expected result as described above?
    thanks!

    First, it should do a new, full backup only if you've gone several days (at least 10) without a backup to that disk (apparently, you can go longer if there weren't a lot of changes); done a full restore (maybe); or renamed your internal HD.
    Second, TM will not delete the last backup to make room for a new one. It will fail for lack of space, instead. So you should be able to restore old files as long as those backups remain. That's why your TM disk should be at least twice the size of the data it's backing-up (and preferably 3 times).
    But remember, if you created a file after the last backup to one disk, and deleted it before switching back, your only backups of that file are on the other disk.

  • USB Hard Drive that Disk Utility says it can't unmount

    I have a 93.2 Gb Hard Drive (from an old G4 PowerBook) inside an enclosure with USB connection. While trying to recover data from it using Data Rescue (on a G4 PowerBook), Data Rescue II hung. After restart, the USB Hard Drive can not be read at all. Disk Utility says it can't repair it or erase it because it can't "Unmount" the disk. What can I do with the USB Hard Drive?

    try this: open system preferences/spotlight/privacy and drag that external into spotlight privacy then try Disk Utility.

    Note that you cannot just reformat the drive. You must re-partition the drive. Open Disk Utility and select the drive entry (the one with the mfgr.'s ID) from the leftside list, then click on the Partition tab in the DU main window. Select one partition from the dropdown menu. If you want to use the drive to boot the MacBook, then click on the Option button and select the GUID partition scheme from the dropdown menu. Click OK, then click on the Partition button. Wait for the volume to mount on the Desktop, then quit DU.
