USB2.0 PCI cards that use the NEC chipset seem to give the least amount of problems for Mac users.
OWC have a few different ones for sale.

Do you also connect the external USB drive to the AC power as well while you use it ?
Sometimes USB external drive problems are resolved simply by plugging them into the mains power and trying again.

Ok here goes. I have so much music I don't want to store it all on my computer and would like to store on an external hard drive. So if all my music is on the external hard drive, how will iTunes see it in order to play the music. Thanks

I have a MacBook Pro 2007 and I installed Mac OS 10.6 but I lost power in the process and now the mac doesn't recognize my hard drive, how can I fix this

I've tried it but since I'm using a USB disk drive it keeps freezing up or showing you a folder blinking folder with a question mark. (?). When I start the mac up I hold the control button until the Mac OS install disk shows up. My hard drive doesn't show up anymore. Is there any other button I have to hold down to bring a different menu up. I have also tried to boot up holding control and C and nothing happens. Thanks for the help so far

I need to delete a lot of duplicates on iPhoto. I just bought my MacBook Pro and was so excited I downloaded my external hard drive without thinking through the process. I now realize I had my photos doubled up. So I actually have the same library twice.

Hello All!
I am so excited about my new computer and I didn't know that my external hard drive had so many pictures duplicated on it. So I downloaded the entire hard drive. I thought iPhoto was going to be my answer, and now after reading a lot of discussions, it seems I have royally screwed up. Please help me fix this problem. I am a computer novice. An even more Mac novice. I need very simple directions. I would just start over with iPhoto, but I downloaded my digital camera with brand new photos on iPhoto and also downloaded my digital camera software on my new MacBookPro. I am afraid if I "start over" with iPhoto I will lose my digital camera pictures. I bought the Mac to finally get my pictures straight, and look at the mess I have made. I had AVG PC cleanup and used that program last night to delete duplicates from my PC. I also used it to delete duplicates from my external hard drive. I omega. I know, I know, too late huh? But I am teachable. And I now have my external hard drive fixed. But now, my question to the community is how to fix my new Mac, and my iPhoto.
Thanks,

When you say to remove the photos out of the iPhoto folder, then import the clean single copies, I am understanding that the "original" file that the decloner was run against is now the "clean" single copies?
Ok, you've got iPhoto Library that you have imported everything into, you can't delete the iPhoto Library and start over because you have only one copy of some pictures in there, combined with a lot of duplicates.
You want all the duplicates out, but it will take you ages to do it by hand.
What you do is.
1: Right click on the iPhoto Library and "Show Package Contents"
2: You will see a folder called Originals, these are all your original photo's, copy this folder to a external drive someplace, it's your backup.
3: Select the Originals folder again and from the Finder Menu > File > Duplicate.
4: Now you will have a OriginalsCopy folder, move that OriginalsCopy folder onto the desktop area out of the iPhoto Library folder. Close the iPhoto Library folder/window.
5: Download the Decloner software and install it, use it to find all the "real" duplicates, via it's content on the OriginalsCopy folder.
6: From the Finder menu > New Folder, now send the duplicate files to that folder, so all that is left in the OriginalsCopy folder is 1 copy of your pictures, minus all the duplicates which are now in New Folder.
7: Open iPhoto and remove all your pictures in there. The iPhoto Library will update to become empty.
8: Now import the pictures from the OriginalsCopy folder, these will now have only one copy of each picture.
9: Open your New Folder, from the Edit menu > Select All and
10 From the Finder > File Menu > Open With > Preview.
Now you have one copy in your iPhoto Library and the duplicates in a New Folder opened with Preview which you can compare to make sure.
Make as many backups of your pictures as you think you need during this prcess, but eventually you only want 1 picture of all you have in the iPhoto Library.
Some pictures may be the same thing but a little smaller etc., these obviously are not duplicates, and you can weed those out by hand in iPhoto.
Good Luck.

Formatting will erase the drive.
You need to copy the photo's to either your old computer, the Mac Mini or to a new external drive and then decide what to do with your existing external drive.
For example: You could use one External drive for Photo's and one external drive for Time Machine to backup both your Mac Mini and the Photo drive.

I recently updated my 20-inch, Mid 2007 iMac with the latest OS 10.8.5 now my external hard drives will not show up. They show up when I boot them up on a machine running and earlier OS. Is there a fix for this?

Can you see them in Disk Utility?
If so, can you select and Mount them?
If not, disconnect them, reset the iMac's SMC and then reconnect them.
Intel-based Macs: Resetting the System Management Controller (SMC)
1. Shut down the computer.
2. Unplug the computer's power cord.
3. Wait fifteen seconds.
4. Attach the computer's power cord.
5. Wait five seconds, then press the power button to turn on the computer.
If you still can not see them, connect them back up to the iMac running the older OS, open Disk Utility and look to see how they are partitioned and formatted.

Oh ok, well that was what the test said prior to reformatting the hard drive. Now, it doesn't find any trouble no matter how many times I run it. That's what has me so confused, everything seems to check out and yet...I can't do anything, not even install the software!

I have a new MAcBook Air and my photos don't fit on the internal hard drive. I want to store my photos on an external hard drive which I will connect to my Air when using Iphoto. How do I set an external hard drive as the default drive in Iphoto?

Make sure the drive is formatted Mac OS Extended (Journaled)
1. Quit iPhoto
2. Copy the iPhoto Library from your Pictures Folder to the External Disk.
3. Hold down the option (or alt) key while launching iPhoto. From the resulting menu select 'Choose Library' and navigate to the new location. From that point on this will be the default location of your library.
4. Test the library and when you're sure all is well, trash the one on your internal HD to free up space.

My Macbook air flash had gone for a month and I saw Apple's Macbook air flash storage drive replacement program. I'm not sure whether that program is still available for the broken device or not. Now, I'm booting from the external hard drive. Thank you.

My Macbook air flash had gone for a month and I saw Apple's Macbook air flash storage drive replacement program. I'm not sure whether that program is still available for the broken device or not. Now, I'm booting from the external hard drive. Warranty has gone in October 2013..
I want to send back my macbook air back to apple store. The problem is that I bought it from US and now, I'm using it in Myanmar. If the program is free of charge for my device, it's worth trying to send back to US. Since mine is broken, I'm afraid Apple will take charges for reparing.
So, if anyone having the same problem as me, I would like to get suggestion....
Thank you!!

I have no idea about how to handle the international aspect of your question.
But here is the Apple writeup about the problem and the remedy. Maybe that will help you.

I made a bootable disc on an external hard drive, with Yosemite on it. I am running Snow Leopard on my iMac. How can I open the Yosemite disc from the desktop on my iMac? Does the external hard drive need to be connected to my iMac by firewire to do that?

Snow Leopard's Startup Disk pref can’t see Yosemite volumes. So the only way to switch from Snow Leopard to Yosemite is to do what Niel mentioned. Doesn't matter whether it's connected by USB or Firewire, although performance via FW would be faster.
Are you saying that Yos/10.10, as a volume located in a mounted external drive won't appear as an option in Snow Leopard's Startup Disc, in Sys Prefs? I've never heard this one before. AFAIK any mounted volume, regardless of OS, should appear there. I would think that, if it appears in the Boot Picker/Startup Manager it would also appear and could be booted to from Snow's Startup Disk. I can't test this myself, since I don't have Yos. Is what you are saying documented somewhere?

I want to take files from my PC (using a Seagate external hard drive) then plug this Seagate External hard drive into my Mac Book Pro and move the files from the Seagate External Hard drive onto my Time Capsule. I do not want to put these files on my Mac. How do I do this? Where do I put these files on my Time Capsule? Will it affect the functioning of my Time Capsule?

Mixing files with data is not always great idea.
See info here.
Q3 http://pondini.org/TM/Time_Capsule.html
Why not just connect the PC directly to the TC by ethernet and copy the files over?
It is hugely faster and much less mucking around.
In windows load the airport utility for windows.. if you have not already as this will help you access the drive.
There is more info here.

I may have found an answer here:

They only thing I can assume is that my external hard drive was slow to start and iTunes defaulted to its old directory (see the last paragraph at the link above). However, once my external was recognized shouldn't everything have fixed itself?
