Access permissions to external hard disks and media players

I've recently purchased an iMac. I have a number of external disks and media players that when connected are not allowed write access. When I use the disk utility I cannot change the permission from read only. Whats the solution to changing them to read and write access?
Thanks

Hi Kieran
Welcome to Apple Discussions
You can not write to them because they a formatted windows NTFS.
See > http://www.macworld.com/article/51972/2006/07/ww_drives.html
If you want to use an external disk with both PC's and Mac's, you will need to re-format it MS-DOS/FAT-32.
If you wish to use them with only the Mac's, you will need to Format then GUID partition/Mac OS X.
See > http://www.kenstone.net/fcphomepage/partitioningtiger.html
*+Proceed with caution when re-formatting disks+:*
1. Before re-formatting any drive you will need to backup the current data on it to a computer or another drive, because re-formatting will erase all the data on the drive.
2. Fat-32 has a file size limit of 4GB and will not allow single file transfers greater than 3.7 or 3.8GB.
3. You may not be able to change the format or write to many media players without special software.

I have transfered all my library on an external hard disk and lost the itunes library files.

I transfered all my library on an external hard disk and lost the itunes library files. Itunes created new ones but I lost all the playlists.
How can I copy the playlists presents on the Iphone directly on Itunes ?
If I want to syncronise now, I lost all playlists datas.

Hi,
I did the same XP to Windows 7 upgrade about 18 months ago. I decided to keep iTunes permanently on the external drive than the c drive to save c: drive space.
ITunes database has pointers to MP3 files located in Artist's directories. If you want to use a different location than the default C:\ drive for iTunes, then you need to recreate the Itunes database by deleting all songs in iTunes, then change the default location for iTunes files to your external drive. Then import the MP3 files from the external drive into the empty iTunes database through the iTunes import facility.
If you screw up the timing of the import and find you have multiple iTunes directories (instead of just the default location), then iTunes has a new feature to consolidate all iTunes MP3 files back into the central default location. In iTunes, FILE, LIBRARY, ORGANIZE LIBRARY, then CONSOLIDATE FILES.
To change the default directory for MP3 files, in Tunes go to EDIT, PREFERENCES, ADVANCED and then CHANGE the location to where you want the Itunes MP3 files to be located (including the iTunes subdirectory under which all the artist directories are held. Mine are on the F: drive or whatever your computer states is your drive assignment for the external drive.
Note iTunes 10.5 has many problems that Apple hopefully are working on....we seem to have gone backwards on working components in this iCloud based release. So maybe keep on using old computer until 10.6 is released.

Hi,
I am using Windows 8.1
I have an External Hard Disk i have partitioned it to 4 parts.
One drive is now inaccessible due to sudden power failure while listening Music from that drive few days ago.
Now it shows "Data error (Cyclic redundancy check)".
I tried all the procedures provided here like
chkdsk /f, diskpart, rescan etc
but no result :( (i mean all processes failed. They could not detect the drive).
Please help me to get those data, pictures and project files.
thank you

Should I boot from external hard disk and how do I achieve this?

I'm in a downward spiral and need advice about if booting off of an external hard disc is the right thing to do and how to go about it. How I got into this mess I'll write below. My immediate problem is that I want to be able to install a copy of osx 10.5 from the original disks that came with my computer onto a usb hard drive. Then I want to boot from that drive and install software such as disk warrior on the same external hard drive in order to repair and recover the files on my internal hard disk. Not sure if this is easy to do with the install disk that came boxed with my macbook. So is what I want to do feasible and how do I do it? Thanks.
How did I get into this mess?
For those with time to read more. A downward spiral (and my macbook was working fine)::
I have been backing up my work documents onto a 20 GB pendrive waiting to get the money to buy an nas to work with time machine for the two macbooks we have at home as a place to backup photos and video. I bought a network drive but it wouldn't work with my macbook; my time machine backup freezing at 3 gb, but works fine with wife's macbook pro.
I tried to do TM backup on a usb hard disk and got the same problem. Support forums indicated that hard disk problems could confuse TM, so although I was experiencing problem free computing I ran disk utility from internal osx. This indicated an <invalid node structure - file system verify or repair failed> at the checking catalog file stage. So I followed instructions to run disk utility and repair from the installation disk. When I ran disk utility from installation disk I get exactly the same <invalid node structure - file system verify or repair failed>. It gets worse.
After failing with install disk utility, I could not then boot from my hard disk (I had had trouble free computing up to my attempts to use TM) or eject the disk. At first attempt I had no option but to boot from dvd again as hd not offered as an option. Second attempt hd option available but fails. By reading advice given to others I managed to eject the dvd and have tried:
safe boot - it won't
boot in verbose mode and single user (indicates I have disk0s2:I/O error) and won't boot
try to use disk utility from install disk to create disk image on external hd, it won't (cites i/o error)
If I can boot from an external I will try to repair with Disk Warrior as forums indicate that this software has been able to solve <invalid node structure> issues (but am open to recommendations of other products). I also hope that I may be able to try again to burn a disk image sucessfully if this repair works. I'm still trying to save my photos and videos that aren't backed up.
I plan to try an archive and install installation but first I want to try a repair with disk warrior as I fear that archive and install won't work and I'll end up having to erase and repair my hard disk.
I feel like some perverse god is punishing me for trying to do the right thing and back up my hard disk.
Macbook 5.1 late 2008
Intel Core 2 Duo
OSX Leopard 10.5.8
85 GB of a 150GB hard disk needs backing up (saving)

I am not sure about this, but my memory is that if you try to partition the drive (in OS 10.5.8) it will erase the data.
But you can try. Go through the Add a partition steps, but watch for any warnings. If my memory is correct there will be a message to the effect that everything will be erased. If you see that, do not proceed. This page has info about how to do it, if it can be done: http://www.macworld.com/article/1164643/live_partition.html
With respect to DW on an external, I do that. I have a 80 GB external - I call it Emergency - with an OS, DW and TechTool Pro on it. (Since I have is a recovery partition built in with all new OS, Emergency would be of use only if I need to run DW or TTP.) I have never yet had to use it, but it's there. It is not usually connected - I just did that for this screen shot.

Problem with Lightroom 5: how to connect the app with my original pictures which are on a external hard disk and, once this resolved, how to create virtual pictures

A friend has installed Lightroom 5 on my MacBook air. he transferred all my picture that were on my IPhone an on Iphoto on Lightroom but without making virtual copies systematically. He put the original (real?) pictures on a external hard disk under Data_photos folder to allow more memory space on my Mac book Air. My problem now that when I connect the external hard disk with my computer the connexion does not happen automatically. it is like if Lightromm does not recognize the path to get connected to the original/real picture and therefore I cannot see pictures with all their potential and I cannot work on these. I am stuck! What should I do to 1) create this link? 2) create then virtual copies in order to be able to work on my computer without been obliged to connect my external hard disk to be able to use the application Lightroom. The friend who helped me disappeared! He is not in Japan and unable to help me.I hope you can help me. I have been looking for support to apple stores, photo shops, computer specialists but I have not found the expert capable to help me. I am leaving in Geneva. And believe that I should have some one with me physically to resolve a problem which I believe is not a serious one if one knows lghtroom an dinformatic basics... thank in advance to come back to me asap !!!!

I want to put my iTunes library on an external hard drive but leave my favourite songs on the computer to access without the external hard drive and when using iMovie. Is there a way to do this?

I have filled my hard drive, half with music, half with photos. I want to take my music off, and put it onto an external hard drive. However, I would still like to have access to favourite songs and playlists when the external hard drive isn't plugged in. I would also like to access this music to use with iMovie. Is there a way to do this?

You will have to engage a split library which means you will have to start answering questions on this forum because you will need to learn a lot about how iTunes works in order not that have a big mess at the end of it all. It also won't be easy when the time comes to relocate it all to different drives.
You can go to advanced preferences and turn off organize media and copy to items to media folder when adding items to library. Next read about how to selectively consolidate items to the external drive.
Sept. 2010, Consolidate selected content - https://discussions.apple.com/thread/2589812 and April 2014, https://discussions.apple.com/message/25414357
"...selected the new tracks directly in iTunes, Control-clicked on the selection, and saw that now you can consolidate selected items." - http://hints.macworld.com/article.php?story=20090919000326840
Remember that when you start iTunes without the external drive turned on iTunes will present you with a bunch of broken links. If you have automatic downloads enabled with iCloud you may have to turn that off to prevent iTunes from repopulating your drive trying to deal with those "missing" tracks.
If you add tracks in bunches to iTunes and want them to go to different media folders you will need to either add them by holding down the option key while dragging if the desired media folder is not the one set in preferences, or by changing the media folder in preferences. Changing media folder preferences only applies to new files added, not old ones.
Okay, I am going to stop typing because you might just reply to me, "Oh, okay, forget it," and I don't need the exercise.

Slow transfer rate between external hard disk and TC

Hi all,
Yesterday I installed a new 1TB TC and attached to it an external LaCie 500 GB HD and a printer (HP 3325) via a USB hub to it. The thing is that although the transfer from the LaCie to my Mac is smooth via wifi, I can't say the same about the data transfer rate between my LaCie and the TC. Whilst they are connceted via USB, it seems that the speed is just half that from the LaCie to my Mac.
Any of you have faced the same problem or know why that is happening?
Thanks in advance,
Ramon M.

Ramon, Welcome to the discussion area!
You have to remember that the data is not simply going through the USB port from the hard drive to the Time Capsule.
The data is actually going from the hard drive to your Mac (through the Time Capsule) and then from your Mac to the Time Capsule. Therefore it is causing twice as much traffic as a simple transfer between your Mac and the Time Capsule.

How to use an external hard drive and copy files to the disk for mac and windows??

please tell me how to copy files to external hard disk and use it for both mac and windows. there is the fat32 formatting bt i dont wanna use formatting because i already have a lot of content on the exteral hard disk. thank you.

It is simplest to have the HDD formatted to noe common to both Mac an PC. ExFAT is one. But to do that will erase all data on the HDD.
If the HDD id formatted NTFS, Mac can read but not write to it. The solution then is to use a third party application such as Paragon or Tuxera which will overcome that obstacle. These applications do have mixed reviews.
Ciao.

I opened my iPhoto library today which was stored on an external hard drive and several of my videos now will not play at all. The weird thing is that each file shows a duration of 1 second and when I open them it just shows one frame. What the !&%$#@ Where did my original video files go?

Sounds like a good plan, you can never be to safe and having a second External HD is safer than one.
The only thing that I would do different, is setup the 3T as my TimeMachine Backup and then erase and move my Photos, Videos and perhaps even iTunes Media to the 1T. That way you will have room to backup both the Internal Hard Drive and the 1T External Hard Drive to the 3T using TimeMachine.

Itunes library on external hard disk

I have my itunes library on an external hard disk and use two laptops to access the library. It works fine but when I add new music it only shows on the laptop I used to add the music. The only way I can view it on both laptops is by using the add folder command within itunes.
Is there anyway of getting the library to update itself on both laptops to ensure both laptops view the same music all the time?

Why not move your itunes library ITL file onto the exHD?
Then when you add music to it, the actual music file plus the database itunes uses will be available to each laptop.
For example, say laptop #2 has the most recent additions. Close itunes. Find the ITL file, on XP the default path is
\Documents and Settings\username\My Documents\My Music\iTunes\iTunes Library.itl
Drag that over to your exHD.
Now start itunes again, but press *and hold* the shift key. Choose the exHD copy of the ITL when prompted. Now close itunes, connect the exHD t laptop #2 and open itunes again using that shift method.

ITunes showing Album Covers of external hard disk i/o internal hard disk

Greetings from Malaysia again. Searched through the Discussion Group, but couldn't find anything there. Thus, hope to get your assistance on this matter.
I have some music stored in the internal hard disk of my G4 iBook. However, recently I decided to have all my music stored in an EXTERNAL hard disk, ie in addition to what's in the iBook, to sync with my iPod. Both have the artwork or album covers. The issue is when I boot up ONLY the iBook, even without the external hard disk on, iTunes (Version 8.1) is showing the Artwork/Album Covers (and list of music) of the EXTERNAL hard disk instead of what's in the iBook. I've even tried the "Option key/Choose Library", but to no avail. I've even tried changing the location, after starting up iTunes in the Preference settings, but still the same story.
Is there any way to have iTunes reflect the correct Artwork/Album Covers (and list of music) when I have the external hard disk connected, as well as otherwise?
Thanks in advance for your help.
Regards.

Moved the existing library. Created a new one, and moved all the songs to the new library. Subsequently, when using the "Option" key to select the library, it ended up as what I wanted, ie iTunes showing the album covers for the songs/album in the respective library - ie external hard disk, and internal in the notebook.

External hard disk not detecting

Hi, I am using WD 1 TB external hard disk and it was going all good till now one day my friend asked for my hard disk as he need to back up some data and connected it to PC. Now I am trying to connect it to mac but mac is not detecting.
My hard disk has all my softwares and other important data.
Need help ASAP

repair disk just checks for errors
likely its a PC formatted HD, thats why you cant read it
Formatting ERASES a HD, so dont do that to the other persons HD.
check what the format of it is. If its NTFS youd need an APP like Paragon to read / write to it.

- Save the following files from the old PC:
-- 1) The Library database file: ‘iTunes Library.itl’ located in the ‘iTunes’ folder
-- 2) The Library XML file: ‘iTunes Music Library.xml’ located in the ‘iTunes’ folder
- Copy these files to your new PC somewhere safe
- Install iTunes on the new PC
- Configure your ExHD to attach to the new PC as the same drive letter as on the old PC
- Attach the ExHD to the new PC
- Copy the two saved database files (XML & ITL) into the 'My Music\iTunes' folder of the new PC - replace the smaller, new files that are there
- Open iTunes
Your new PC's Library should be a clone of the old PC's. These are high-level instructions. If you feel you need more, post back.
