Why can't I make changes on my external hard drive?

I have an external hard drive that I set up through Windows XP that I can now access through Mac OS X on my MacBook. Unfortunately, I'm not able to delete or make any changes to any of the files through the Finder. Why is that, and can it be changed?

There's another alternative, format it as exFat, 4G limit does not apply and OSX + Windows will be able to read/write.

Why Can't I Copy Files from an External Hard Drive or SD Card?

Major problem here... Why when I try copying files from an external hard drive or an SD card onto my internal iMac hard drive, it doesn't work? The status bar that pops up, shows that it completes the transfer of the files to 100%; however, when it does in fact finish, the files actually do not appear on my hard drive.
Any help would be greatly appreciated. This is one of many problems I have been finding with OS X Lion and am very much on the verge of going back to Snow Leopard.
Thank you.

Have u tried the usual? Safe boot. Delete finder plist files? etc. And the drives are formatted for mac yes?

Why can't I download songs from an external hard drive onto iTunes?

So I have an external hard drive with some songs on it that I wanted to get on iTunes so they can be synced to my iPod. I plugged my hard drive in and then went to iTunes where I clicked on "File" (in the top left corner) and scrolled down to "Add folder to Library". I then found my external hard drive and selected the albums/songs that I wanted.
They loaded onto iTunes just fine. Everything looked right and the songs were all on the list. I even managed to get album artwork on most of them.
Then I went to "sync iPod" and an alert message popped up saying "Some of your songs were not synced to your iPod because they could not be found." (Or something very similar to that)
So none of the songs made it onto my iPod and when I checked the Library list again, all of the songs I had just put on iTunes had exclamation points in front of them.
What am I doing wrong and how can I fix this? Any answers would be greatly appreciated.
Thanks!

Sounds like you
1) added the songs to the itunes database, but did not copy the acutal files to the PC's internal HD
2) unplugged the exHD and now itunes doesn't know now to find them anymore
If you plug the exHD back in, and it has the same drive letter as it did when you added the songs to itunes, it should work.

Why can't I access folders on my external hard drive when I am an admin user?

Early 2011 15" MacBook Pro
2GHz Intel Core i7
Lion
I have a 2TB external hard drive connected to my Airport Extreme that I use to save all of my files. Both my user profile & my wife's are admin users, however she cannot access the external drive at all. It has a red circle with a white line through it when you look at it on finder & none of the folders are listed to change permissions under her login.
When I go to finder under my login, I have selected Read & Write permission for "everyone", but she still cannot access the drive. When I attempt to add permission for her user profile specifically, I am told "The name you entered isn't valid. Please try again"
Help!

Why can't I copy files from my external hard drive - error code -50.

I sm trying to back up an external hard drive to a network drive. Some files copy but not all;. SOmetimes a folder seems to have copied but then I see that most of the files inside have not. And sometimes I just get 'An unexpected error has occurred'. Error code - 50.
I need to have a back up copy of the files on this hard drive. How can I stop this happening and copy files properly and securely?
The external hard drive is a LaCie bought from Apple, share formatted FAT32.
The network drive is a WD MyBookLIve Duo which WD tell me should work equally well with any operating system.
Please advise. I need to archive a security copy of this data urgently

Why Can't I see or access my external hard drive anymore using finder

I have a MacBook using Lion 10.7.5 and I use a Seagate 1 TByte external hard drive to store large photo and video files so that these won't take up space on my system hard drive. I also use the drive to share files with friends, colleagues and family members. Just recently I was no longer able to see my harddrive when I plugged it into the USB port on the Mac. However, when using the Disk Utilities, I was able to see the hard drive but could not access or see the files. Therefore the USB cable and USB port is working from a hardware perspective. The light also was on when I plugged the hard drive into the USB port so I know the hard drive is working. I brought the laptop and hard drive to my local Apply store to see if they could determine the problem. They did everything I already did regarding the testing of hardware. They recommended that I reload my software because something in the OS must have gotten corrupted. I re-installed the OS and the updates to the version. The re-install DIDN'T help. Using Bootcamp with Windows XP which is installed on my MacBook, I wanted to find out if Windows would recognize the hard drive and also give me access to the files. Using Windows, I was able to now see the drive and access the files. I now know the hard drive works, the USB cable and port is working and windows gave me the ability to access all of the files.
THE FIX: The hard drive was stuck in the Windows Mount Mode and because of this, the Mac OS was not able to recognize the hard drive using finder in Mac OS. When I was still in Windows, I ejected or dismounted the dick prior to removing the hard drive from the MacBook. I then shut down Windows and restarted the Mac OS. Once the system was fully up, I plugged the hard drive into the MacBook via the USB port. The Hard Drive is now being recognized by my Macbook once more. I can again access all my files.
HOW THIS PROBLEM OCCURRED: While sharing my hard drive with a colleague to transfer some files on a PC using Windows, the colleague disconnected the hard drive from the PC after the files were transferred by pulling the USB cable out of the USB port without a software dismount or ejection. This caused the hard drive to hang in a "windows mounted state" even though there was no power to the hard drive. When peripherals are connected to either a Mac or PC systems, they should always to properly dismounted via a software dismount or a system ejection. Proper dismount of peripherals will always insure the closure and correct allocation of data within the booting sectors and data fields of the hard drive.

Can I take my old mac and make it into an external hard drive

Can I take my old mac and make it into an external hard drive? It does not work anymore but I would like to make it into an external hard drive. I heard it is not to hard to do myself but I have important information I would like off of it and only really trust the apple store to do it. I know it is possible because I have had a friend that had it done after water went on her laptop. I would like to also know how much is this going to cost and if it is even worth getting done at the store or just do it myself.

Can I put my library on an external hard drive and use it between two computers?

Can I put my library on an external hard drive and use it between two computers? I have two MBP; I will refer to one as computer A and to the other as computer B. I would like to be able to plug in my external hard drive, boot up iTunes, and if there were any changes made to the library previous to its last time accessed on this compluter, they show up on that computer, regardless of being imported on the other.
A hypothetical example: I import three albums called 1, 2, and 3 on computer A over a week or so. I take the external hard drive and plug it into computer B. The entire library which was visible on A, is visible on B, including albums 1, 2, and 3.
Is this possible? If so, what files need to be copied onto the external? I'm trying some different combinations, trial and error basically. Hopefully someone knows and can answer before I mess up my library. I also want to do this to free up space on my computer. All importing will be done from disc.

iTunes/Preferences/Advanced : point your iTunes to the new location of the Library.
Set "Share on local network" in the Sharing tab, and you or everyone on the local network can play your music.
You make a backup first of the Library.
Move the follwing to the new location:
/Users/your username/Music/iTunes/iTunes Music
have fun.

Can I install a program on an External Hard Drive?

I have an 500 GB external hard drive that I attach to my MBP to store movies and my aperture picture libraries. When I first got it, I created three Mac OS Extended (journaled) partitions, one for movies, one for pictures and the other one for “extras”. I’d like to install Adobe Photoshop on my external hard drive, so I’d like to know if there is a way to make any one of my three partitions operate as if they were a system partition. Can I install an application in an external hard drive? Can I run an application from an external hard drive? Which formatting solution could help me achieve what I want? Is this even possible? Any suggestions?

There are many applications that are happy to be installed on a partition other than the boot partition. However, if the Adobe Photoshop installer does no present you with that option I wouldn't. You could always copy it across post-installation to see if it will work. Updating my present issues.

Can I install snow leopard on an external hard drive so I can run quicken 2006, and put snow leopard on my imac harddrive

Can I install snow leopard on an external hard drive in order to run my quicken 2006, and install lion on the hard drive of my imac?

You don't need to erase the drive and repartition from scratch. You may be able to add a second partition on the fly. The caveat here is that once you do that you cannot create a Windows partition using Boot Camp. Of course if you have no plans for Boot Camp then it isn't relevant.
To create a second partition on your existing startup volume:
To resize the drive do the following:
1. Open Disk Utility and select the drive entry (mfgr.'s ID and size) from the left side list.
2. Click on the Partition tab in the DU main window. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.
3. In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed. (Note: You can only make a partition smaller in order to create new free space.)
4. Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.
You should now have a new volume on the drive.
It would be wise to have a backup of your current system as resizing is not necessarily free of risk for data loss. Your drive must have sufficient contiguous free space for this process to work.
Now, you cannot add a new partition that exceeds the amount of contiguous free space at the end of the drive. Disk Utility will fail to add the partition if it cannot find sufficient contiguous free space. If that's the case then you will need to follow your state outline - backup, boot from clone, erase internal, repartition internal, restore backup to one of the partitions (or both in your case.)

I had Leopard on may Mac. I upgraded to Mountain Lion using Snow Leopard. I can't use my video with Mountain Lion. Can I load Snow Leopard on an external hard drive so I can use it with my camera?

First, you cannot do this if you have a Boot Camp partition.
Second: Create a new partition.
1. Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
After the main menu appears select Disk Utility and click on the Continue button. Select the hard drive's main entry then click on the Partition tab in the DU main window.
2. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.
3. In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed. (Note: You can only make a partition smaller in order to create new free space.)
4. Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.
You should now have a new volume on the drive.
It would be wise to have a backup of your current system as resizing is not necessarily free of risk for data loss. Your drive must have sufficient contiguous free space for this process to work.
Third: Install Snow Leopard.
Boot from your Snow Leopard DVD. Follow instructions for installation being sure that before you actually install Snow Leopard you have selected the new partition as your target destination.
Booting From An OS X Installer Disc
1. Insert OS X Installer Disc into the optical drive.
2. Restart the computer.
3. Immediately after the chime press and hold down the "C" key.
4. Release the key when the spinning gear below the dark gray Apple logo
appears.
5. Wait for installer to finish loading.

How can i perform a search on my external hard drive on my mac pro os x 10.9.2 ?

how can i perform a search on my external hard drive on my mac pro os x 10.9.2 ?

Mac OS X 10.9.2 is 12 years newer than 9.2.x. You need to make sure that Spotlight has indexed the external hard drive by adding it and removing it from Apple menu -> System Preferences -> Spotlight -> Privacy. Check the menu for it:
to determine if indexing is still going on, as it will say indexing.
Alternatively, you can use a non-Spotlight tool, such as:
http://apps.tempel.org/FindAnyFile/
http://www.devontechnologies.com/products/freeware/ - EasyFind
http://www.osxbytes.com/ - iFileX (note the MacUpdate link provided on osxbytes page has a Malware advertisement for MacKeeper, do not download).
http://www.barebones.com/ Textwrangler has a Search file for content, which works on any Text file.

How can i update the itunes in my external hard drive?

When i try to update the itunes on my external hard drive, it creates a new application in my computers hard drive. How can i update the one on my external hard drive?

there's no advantage to having the application on your external drive, you should leave it in your applications folder on your internal drive. if you insist on changing the app's location, you'll always have to then copy the app by hand to the external drive

Can airport extreme backup to non-Apple external hard drive?

Can airport extreme backup to non-Apple external hard drive?

Apple does not make external HDDs so you will most likely be using a non-Apple drive for backups.
However, I want to understand your question. Are you asking can you connect an external HDD to an AirPort Extreme for Time Machine backups? If so, Apple does NOT support this feature and I would recommend against it.

Can this device be used as an external hard drive with a macbook pro laptop to use files on the airport?

can this device be used as an external hard drive with a macbook pro laptop and use files on the airport time capsule?

If you mean an AirPort base station other than the Time Capsule, it doesn't have internal storage.
If you mean a Time Capsule, its internal drive can be used for regular file storage but shouldn't be; as with all drives, it'll eventually fail. You're better off using a standalone drive and setting Time Machine to back it up as well.
