Having issues with permissions on external hard drive.

I'm very new to my MacBook Pro, and I'm having an issue with my external hard drive. I used it to bring important files (mostly music) from my windows 7 laptop to my mac. Once I finished that I noticed that I was missing some of my music which luckily I have on CD so I uploaded them to another computer and loaded them onto my EH. This is where the problem occurs, when I drag my music from my EH most of it gets copied, but a small number end up giving me an error and won't go to iTunes. I've dug a little deeper into the issue and it all comes back to not having proper permissions to us my EH. However the songs that were imported still open in itunes when clicked on. I've tried looking for the lock symbol under Get Info, and it isn't there.
Any Ideas?

Yes - with Windows/Mac 'compatibility, it's really a one or the other compatibility - without third party software. Just as Paragon has software that will enable you to read & write to an NTFS volume on a Mac, so they have software for Windows that will read Mac-formatted drives - http://www.paragon-software.com/home/hfs-windows/.
NTFS, with Paragon's NTFS for Mac, is probably the best way to go if you want to 'share' the drive with both Macs and Windows machines.

I am having an issue with connecting my external hard drive to my airport time capsule.

I just recently purchased the new AirPort Time Capsule. The network set-up easily. However, when I connected my external hard drive (via USB) to it, the external hard drive does not show up in my Finder and I am otherwise unable to access the external hard drive from any computer connected the the network. When I plug the external hard drive in directly to my iMac, the external hard drive is recognized right away and I am able to access all folders. Any tips?

Check to make sure that the drive is formatted in Mac OS Extended Journaled or FAT32.
If the drive is formatted correctly and recognized by the Time Capsule, it will appear when you open AirPort Utility and click on the Disks tab.
Open Macintosh HD > Applications > Utilities > AirPort Utility
Click the Time Capsule icon, then click Edit
Click the Disks tab at the top of the next page
If the drive is formatted correctly and not recognized, you will likely need to use a powered USB hub with the drive....even if the drive has its own power supply, since the USB port on the Time Capsule tends to be underpowered.

Having trouble with USB2.0 external hard drive "unmounting" itself

ibook g4 (early 2005)
I have bought an external 120 gig hd and am trying to use it to store files on. when i transfer files to and from it, the hard drive magically unmounts itself and gives an error device removal. I don't know if the HD needs too much power or what. I have tried to update my system... and no help. what can i do... besides taking the freaking hd out of the external case and installing it in my laptop.
I have never had a problem with usb devices before on this laptop. what gives?

I'm not sure of what is the cause for this is, but because it stays alive while it's in use makes me think there is some sort of hardware sleep mode or something. I don't know enough about USB to be sure though. Maybe a temporary fix would be some sort of script we could launch at startup that reads a very small amount of data from the afflicted drive every 10 seconds or so. I have a little programming knowledge. Maybe I can figure the script out. It's definitely not a true fix, but it might get us by for the meantime.

My external drive is full, how do I piggyback it with a new external hard drive?

My old external hard drive is full. How do I piggyback it with a new external hard drive? I am thinking of getting. 2tb western digital my studio for Mac.

Your iMac has four USB ports. If the new drive is also USB, just plug it into one of the unused ports.
Your machine also has a Firewire 800 port. If it is unused, you can connect a new external firewire drive to it.
Note - if you plan on using the new drive for booting (backup or emergency), such as by partitioning it and cloning your internal drive to one of the partitions on it, strongly suggest you go with a firewire drive.
In either case, firewire or USB, it's best to get a drive which has its own power supply.

Not much faster than 40 GBs-60GBs per hour. So, minimally, around 12 hours.

Photshop CS6 not showing as `open-with` for desktop/external hard.drive images

Hi, I have CS6 and am using Photoshop, but when I try to open any image on my desktop the `open with` option dosent include Photoshop CS6, only other Adobe applications; even when I browse I can only find the Adobe systems file, with the .exe doc; I have a lot of images to edit, preferably without having to open Photoshop and individually open them from their folders; any advice on how to make Photshop CS6 `open-with`-able for any desktop/external hard drive images?

Thanks for raising this issue. I found the answer at: http://www.flickr.com/groups/photoshopsupport/discuss/72157630067784368/. Hope it works. I have done it but I believe I must now reboot before trying it.

Having Itunes Library on an External Hard Drive

My laptop has slowed considerably since over half the hard drive capacity has music on it, so I bought an external hard drive. I would like to remove the music library from my computer hard drive and have it on the external drive. Can someone point me to directions on how to do this, or explain it. Many thanks.

I have noticed no slowdown.
You need to have your music, in at least two different places for back up purposes.
a) I have had no issue with "clogging"
b) If your music is on the external drive you will have to have that drive connected and on in order to listen to the music.

Need some help with backing up external hard drive using Time Machine

Hi all, I'm trying to work out the best way to back up multiple iPhoto libraries using Time Machine.
At the moment I have got an iMac and Macbook Pro, both of which have an iPhoto library (with different content). Currently these are not backed up at all. So what I want to do is back both up to an NAS drive, which I know is straightforward.
What I also want to do is create one iPhoto library on an external hard drive that I can use with my MBP, and then delete the iPhoto library on my MBP to free up some hard drive space (it's running slower and slower and I'm hoping that this might help it run quicker).
So, as I want to have the library on two seperate drives in case one fails, what I want to know is whether I could use Time Machine to back up my external hard drive as well as the internal drive of my MBP? Also, would I need to have the external drive connected at all times for Time Machine to "see" it?
I hope that makes sense, all I seem to be doing currently is going round and round and can't work out whether what I want to do is possible or not.
Thanks in advance

If I understand your goal correctly, you're considering using Time Machine as external storage, and it doesn't work that way. Time Machine keeps around what it can, and older stuff gets flushed as the storage available to Time Machine reaches its lower threshold due to the addition of newer stuff. When the older stuff gets flushed is not predictable.
It is possible to have several Time Machine backups aimed at the same target (this can be done with Apple Time Capsule, for instance), though you might want to partition the disks to ensure that the intended amount of storage is available. Different NAS drives have different features here.
NAS is only as fast as your network connection, and that's almost always much slower than the in-box I/O connections; a local disk will be far faster than a NAS disk, just because of the bottleneck that is wired gigabit Ethernet, and most WiFi is slower and sometimes far slower than wired gigabit Ethernet. FWIW.
If your MacBook Pro is old enough and you have $$ but aren't in a position to spend $$$$$ on a newer model, then consider an in-place drive upgrade.
If your network connection is fast enough to transfer the amount of data you're dealing with in a reasonable time, there are also hosted storage options.
You can use a NAS drive as storage independent of Time Machine, and relocate stuff there. (You'll still want to have backups of that data, as NAS drives — even NAS with RAID — can still lose files, become corrupted or otherwise ruin your data day.
As for your performance, keeping about 10% or so free on the disks is the local preference, but it's worth reviewing the performance of the whole system — Performance Monitor, Console.app, etc — to see if there's something else going on, or if your system load and personal performance expectations are exceeding what your MacBook Pro can provide.

Using Time Machine with a Used External Hard drive

I had posted a question before about using an external hard drive that I have for a Time Machine back up that already have some stuff on the hard drive, and if using it for Time Machine would erase the info I currently have on the drive.
I got a response that said if it was formatted as Xsan or Mac OS Extended with or without case-sensitivity or journaling, it would not erase my current info, but otherwise, it would.
When I checked the format on my external hard drive, it is listed as "MS-DOS (FAT32)". Does that mean it is the Xsan/Mac OS extended (that wouldn't erase my current information) or does it mean it WILL erase my info?
Thank you!!

Does that mean it is the Xsan/Mac OS extended (that wouldn't erase my current information)
No
does it mean it WILL erase my info?
Yes. FAT formatted drives are for use with Windows.

Issues after using an external hard drive.

I have a 15 inch macbook pro bought in mid 2009 and never had a problem with it till I decided to backup my files to an external hard drive. I plugged in the hard drive last week and now when I startup and login to my account my mouse often doesn't work (clicking won't register and I can't click on ANYTHING) and/ or the dock (which I have set up to hide) will not appear, forcing me to hold down the power button to restart my laptop. Restarting in this way sometimes works and puts everything back to normal. Anyone have any suggestions on how to fix this?
Additional information:
The hard drive I bought is just a WD passport that I erased through timemachine to format it for the Mac system.
I also have antivirus, have done a scan and nothing pops up.
I'm running the most recent version of OSX Lion.

It should be as simple as just setting the library location on each computer to read from the external drive
It is.
Sounds like you are referring to the *iTunes music folder* location in the prefs. This is not the same as the iTunes library.
The iTunes library file is located by default in \Music\iTunes\ on yoru boot drive.
This is all the info about what you have in iTunes. It is also the default location for your music but that can be changed in iTunes prefs -> Advanced -> iTunes music folder location. Changing this will change ONLY the location of the music, not the iTunes library.
Powerbook has no problem reading the iTunes Library on the external.
Great! Do this.
Connect to the drive Powerbook.
Copy the entire \Music\iTunes\ folder from the PowerBook drive to the external drive.
Hold Option and launch iTunes.
Select *Choose existing library* and select the *iTunes library* file in the *iTunes folder* you just copied to the external.
Everything should work.
Go to iTunes prefs -> Advanced and set the *iTunes music folder location* to the iTunes folder you hust copied to the external.
Tick *Keep iTunes music folder organized* and tick *Copy files to iTunes music folder when adding to library.*
Now go to File -> Library -> Consolidate.
This will copy everything in iTunes, into the iTunes music folder in the iTunes folder you copied to the external.
Quit iTunes and plug the drive into the other computer.
Hold Option and launch iTunes.
Select Choose existing library and select the *iTunes library* file in the *iTunes folder* you copied to the external.
Everything is there with same playlists, ratings, date added, artwork, etc.
That's it.

Logic board failure on Mac Book Pro. Backed up info via time machine with sea gate external hard drive. Help!

I now have no access to any mac now, and the old mac while it still has my old information freezes immeadiatley upon starting. I am therefore switching to PC laptop that has be graciously given to me. My question is how do I get my information off my external drive, and on to my new laptop? The laptop is an Asus with windows vista, and I am planning on upgrading it to Window's 7. All my information from the past 3 years of college is stored in this Seagate 320 gb external hard drive. What do I need to do?

OK… firstly try the USB port on the other side and see if it makes any difference. Otherwise, do you have any better luck using the drive when it's connected through an AC powered USB hub.
To check if your MBP is seeing your drive at all it should appear in the USB section in the System Profiler utility.

Setting Up Time Machine with a Partitioned External Hard Drive

I recently bought a new external hard drive (MyPassport) and I was advised to partition it in order to keep my movies/music files separate from the rest of my files. So I partitioned it, but now I can't figure out how to set up the Time Machine with 2 separate hard drives. Is there a way to set it up so that I can use Time Machine for both, one for movies/music and one for everything else?
