How to read external hard-drive from all users

Hello everybody !
I have a Lacie Porshe Design external hard-drive for my Mac.
I have 2 user accounts which both are "admin".
Since yesterday, when I plug my external hard-drive, I cannot read the files on it unless I'm on the first "admin" account. I want to read the files from all the users account. There's a little red stop sign on the files and it tells me I have not the permission to view the files when I'm on the second user account.
Why does it work only with the first "admin" account and not the second one ? How to I disable this ?
It worked perfectly yesterday and I have no idea why.
Thank you very much guys !

I am sorry for the confusion.
The technician fresh-installed all the programs needed on a session they created called admin. On it there is all the programs but nothing else.
In case of trouble with the programs and licenses, the techicians asked for us to leave this ADMIN session untouched and to do our project and personnals things on our own new session.
So I got
ADMIN - only the programs installed by the technicians, admin status enable first
PERSONNAL - all my personnal files and the programs installed by the techicians, admin status enable later
When I read my Lacie Hard-Drive from the PERSONNAL account, I do not have the permission to read my old Time Machine backup files from my previous mac even thought the PERSONNAL account got the admin status enable. But when I read the Hard-Drive from the ADMIN account, I can read those files.
Hopefully this is clearer.
Thank you for your time !

  • How to read external hard drive photo's on iphoto

    I have all our photo's (nearly 56GB's) stored on an external hard drive for fear that one day my iMac woudl crash.  Everytime we'd load a photo, it would load to the external hard drive, and the 'old iMac' iPhoto would read it from the hard drive.  That computer crashed.  We're now using my wife's MacBook Air, but that only has a 64GB flash drive, so loading the photo's onto that will not work. How do I set up my wife's MacBook Air to read the photo's on the external hard drive?
    I'm running OS 10.7.4

    Have you got that disk backed up?

    Simply, that drive is far more likely to suffer damage than your Macs HD.

  • How to create External Hard Drive from Internal Hard Drive?

    For my Mac, I want to get a 250GB external Firewire Hard Drive. I know I can purchase one as is. However, it seems that money can be saved by purchasing an internal hard drive and a hard drive enclosure. Is this correct?
    If so, would the internal hard drive be an IDE?
    Is there an enclosure that will make this IDE drive a Firewire/USB external drive?
    Should the enclosure have a fan, on/off button?
    Anything else to consider.
    Thanks,
    Herschel

    Hi Hershel.
    1) If you want to use the drive with both your PC and your Mac then you have two options. Either you format the drive in FAT32 (standard windows format) or you get hold of one of the utilities which allows you to read Mac HFS+ formatted disks on a PC (IMHO the better way to go). One disadvantage of using Fat 32 formatting for the drive is that you then won't actually be able to use it as an emergency "startup disk" for the Mac . The other problem is that Fat 32 can be problematic with large disks and files sometimes.
    2) Your iMac has both USB2 ports and firewire 400 ports. There is no advantage really in getting an enclosure with Firewire 800 , because your iMac is limited to Firewire 400 anyway. The drive you buy to insert in the enclosure won't have any effect on this.
    3) The reasons for getting a firewire capable enclosure for use with your Mac are that it is actually faster than USB2 (despite the higher rated speed of USB2) and because you can start up your Mac from an external FW drive, but not from an external USB2 drive. If you are formatting in Fat32 this won't be an issue because you won't be able to boot from it anyway.
    4) The business about "parallel" and "serial" drives relates to the type of bridge in the enclosure that you buy, not to whether you want to connect it to a PC or a mac. Some enclosures are designed to work with "SATA" drives - ie Serial. Some are designed to work with "regular" IDE / ATA drives (ie parallel).
    Just to make this clearer , think about this as involving two links in a chain. THe first link is from the drive to the enclosure. The enclosure needs to have the right sort of INTERNAL connection for the drive you buy - either SATA or regular ATA - regular ATA enclosures are more common than SATA one but large drives are now easier to find with SATA interfaces than IDE ATA. A few enclosures can accept either type of drive,but they tend to cost more.
    The second link is the EXTERNAL one from the enclosure to your computer. In your situation it sounds as if you ideally need one which has both Firewire 400 and USB2 connections. (THere are also some cases which provide am external SATA connection for connection to the computer, but you wouldn't be able to use this with your iMac as it has no external SATA port).
    Try a Google for the IceCube Pleiades and you should be able to come up with prices in a place somewhere near you. At present I'm not sure which country you are in.

    Also, Im a photographer, so I like to name a lot of files at the same time (used to do in on PC and it was very usefull.) cannot find out how to do it on my Mac. Really appretiate if some one can give me a solution! Thanx

    Your drive is formatted with the NTFS file system.  OS X can read but not write to the NTFS file system.  There are third party drivers available that claim to add the ability to OS X to write to an NTFS partition.  I have not tried them and don't know if they work.
    The only file system that OS X and Windows can both write to natively is the FAT32 file system.

  • How do you transfer info from an external hard drive from a PC to a Mac

    How do you transfer info from a external hard drive from a pc to a imac?

    Expanding on what Niel said, a Mac can mount and read just about any hard drive from a Windows system. It can't write to an NTFS-formatted drive without third-party drivers, but it can read them. So as Niel indicated, you should be able to just connect the drive to your Mac and drag-copy over whatever you want. If you want to save things from the Mac to that drive, then it will need to be formatted either as FAT32 or exFAT, or if it's NFTS you'll again need drivers.
    Regards.

  • How do you dump a external hard drive from PC to mac

    How do i dump my external hard drive from a PC to my Mac

    If you don't see the external HD when you connect it to the Mac, then you need to use Disk Utility to format the XHD to a FAT32 drive. Once done it will read on the Mac and PC without any problems.

  • How can I make a backup to an external hard drive from iPhoto if it won't open?

    how can I make a backup to an external hard drive from iPhoto if it won't open? I just wan't to make a backup to my pictures not my entire computer so how does Time Machine work on that?

      you could also clone the drive or volume, or just some of the user folders. look for carbon copy cloner, then enable the "use checksum to insure file integrity."
      you can have multiple iPhoto Library catalogues in different locations.
    Continue to use TimeMachine and make sure it has 350% or more capacity than your system and data.

  • How do I connect my external hard drive with all of my digital media to my Apple TV network and make it accessable 24/7?

    How do I connect my external hard drive with all of my digital media to my Apple TV network and make it accessable 24/7?  I have the latest Apple TV, ipads, iPhones as well as a solid HP Windows machine all on my home network.  Is there a way that I can connect my hard drive to my receiver or Apple TV directly so that the digital media is available on my network 24/7 rather than have it connected to my computer and available through Home Share which never works anyway??

    Sorry it's all done through iTunes.

  • I have an external hard drive from my time capsule that stopped working on me. I am attempting to access the data with a hard drive reader on my MAC. I am able to see the drive in disk utility and under system info USB. But I am unable to access the data.

    I have an external hard drive from my time capsule that stopped working on me. I am attempting to access the data with a hard drive reader on my MAC. I am able to see the drive in disk utility and under system info USB. But I am unable to access the data and it does not show on the desktop when connected.

    Ok if disk utility was able to verify the drive I doubt there is any problem.. are you trying to open a TM backup??
    You need to mount the sparsebundle then check the actual info inside the bundle.
    Don't use disk warrior.. if the disk has verified then unless you deliberately deleted files there is nothing that is going to do.
    Pondini has a lot of stuff about getting access to the sparsebundle.

    But if you have copied info to the TC that is now gone.. and the disk is ok.. I am not sure.. the TC will not have deleted the files itself.

  • I transferred my itunes to an external hard drive from my mac, now all of my music needs to be located. Help...

    I moved my itunes library to an external hard drive, now all of the music says it needs to be located. Not sure, but I believe it is not directed properly.

    if you do iTunes > Preferences> Advanced you can change the location of where your music is stored.  Click on change location and direct it to your external hard drive.  Of course, your external hard drive will need to be connected to your computer to play the music. 
    When you moved your music to an external hard drive, did you copy the folders or move the folder off your computer completely? I copied the folders, and left iTunes folder in my Music folder and all seems to work fine. one hitch can be is that your Library in iTunes will list all of your content, but if you have some albums on the hard drive of your computer and some on your external hard drive, iTunes will need to be told where to locate these files.

  • HT4914 My music is stored on an external hard drive. All music that I buy, whether from itunes or some other provider, automatically gets loaded onto my external drive. There is some music on my computer drive as well. Will match work in this circumstance

    My music is stored on an external hard drive. All music that I buy, whether from itunes or some other provider, automatically gets loaded onto my external drive. There is some music on my computer drive as well. Will match work in this circumstance?

    I followed all the instructions for consolidating my music into one folder on my external hard drive. (I'm struggling with this because my ext HD was renamed when I synched my iPod shuffle last night. The "E:" drive has now become the "F:" drive and all my songs have those dreaded exclamation points next to them. Exploring my computer, I found "My music" folders in two place on my C: drive and one place on my external hard drive... and the song list in each place is different.
    Argh.
    So... following the directions in the article reference here, I attempted to consolidate all of my songs into one folder on my external hard drive.
    But.. I checked the song list when the "consolidation" was complete... and MANY songs are missing. They're still on the C: drive, but don't appear to have been copied to the new folder on the ext HD.
    I would appreciate any suggestions.
    Thanks so much!
    Edit: I tried to reassign the ext. HD a permanent letter, but my Control panel does not appear to offer the option of Administrative tools. Is there an easy way to get to this, as this seems to be the root of the problem?
    Thanks.

    I want to move my music and photos to an external hard drive from my iMac.  What kind of hard drive should I get?  Will it remove it from iMac and only be on external hard drive?

    How to correctly move your media:
    iTunes: How to move the library to an EHD
    iPhoto: How to move the Library to an EHD
    It is important that the External Hard Drive is formatted as Mac OS Extended (journaled).
    And also make sure that all is working to your Satisfaction before Deleting anything Off your Mac.
