Hi,
Yes, like Vegan said, you should check if your Seagate hard drive if it could available in USB 3.0 port. This is hardware related.

How do I reformat my External Hard Drive (Seagate Backup Plus).

Hello everyone. How do I reformat my External Hard Drive (Seagate Backup Plus Portable Device). I accidentally clicked to use it with Time Machine and my hard drive is of little use now. When I open my hard drive, it just shows 'backup', the same thing when I open it with Windows. Thinking of reformatting it back to be used to Mac and Windows. And not use it again with Time Machine. New to Apple, appreciate the help

Hello,
"Thinking of reformatting it back to be used to Mac and Windows. And not use it again with Time Machine"
If you want to format the External drive as universally compatible, your best bet is to format it as exFAT. Note that reformatting the drive erases all contents of the drive.
1) Open Disk Utility located in /Applications/Utilities/ (or simply type it in spotlight and the application will show up)
2) Select the external Hard drive
3) Click the 'erase' tab.
4) Under format: select exFAT
5) Click "Erase" in the lower right hand corner to reformat the drive.

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

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.

Can't drag and drop my iPhoto library on to an external hard drive (Seagate Go Flex).

I am trying to move my iPhoto library to an external hard drive (Seagate Go Flex wireless) but it won't let me drag and drop. When I drag the iphoto icon over the 'drop files here' it just disappears. No error message. I am running mountain lion. What can I do?

Susie,
(Seagate Go Flex wireless)
What is your iPhoto version? And your Mac OS X version?
With iPhoto '11 your iPhoto library needs to be on a drive formatted Mac OS X Extended (Journaled). Is your external drive formatted this way? If your drive is formatted differently, iPhoto will not be able to open the iPhoto library there.
When I drag the iphoto icon
And are you really trying to drag your photo library (from your "Pictures" folder) or your iPhoto application from the "Applications" folder? On MAcoS X 10.7 or later you will not be able to drag the application from the Applications folder.
Regards
Léonie

I am a novice - I need a simple, plug & go, external hard drive ... Have read various reports about Time Capsule ... Any opinions or alternatives? I am old, & need simple answers please - nothing complicated ... Thanks ...

I am a novice - I need a simple, reliable, plug & go (U.K.) external hard drive (1-3 TB) Have read various reports (good & bad) about Time Capsules - opinions & alternatives please .. I am old, so please keep answers simple - anything containing 'stuff' I won't understand & I'll ignore it .... Thanks in anticipation ...

I consider Time Capsule slow, mainly because it depends upon a wireless network for backing up. I tried it, but went back to the plug and play FW800 wired backup. Since this particular forum is for the MacBook Pro hardware, I'd suggest the following two forums to search for your answer (or ask questions):
Time Machine
Time Capsule
Since you want easy, the external hard drive is about as easy as it gets. Buy. Unpack. Plug into your Mac. Format (if you don't buy a Mac formatted one, which is unnecessary). Go to System Preferences>Time Machine. Choose the disk as the time machine. Turn on.

External hard drive setup for time machine reading as a virtual cd

Why is my MacBook Pro reading my external hard drive setup for time machine reading as a virtual cd?
Thanks

Hi Christian,
Is this something that has happened from the start? If so, I would reformat the disk and setup TM from scratch again.
Prepare the external HD by connecting to the Mac, open Disk Utility, select the manufacturer’s name of the external HD, select Partition and choose GUID Partition Table, format to Apple OS Extended (Journaled); quit Disk Utility.
Open System Preferences.
Click on Time Machine.
Click on “Select Disk.”
Click just to the left of "On" to turn TM on if it's not already on.
Click on the disk or partition you want to use.
Click on “Use for backup.”
Leave external HD connected, and TM will automatically do its thing.

Every time I try to back up my Macbook Pro with an external hard drive using Time Machine, I receive the error of "the disk does not have enough space". I have a 500GB hard drive and only 120GB Macbook. It worked fine before the latest Maverick's

My guess would be it has created an entirely new backup of your drive when you upgraded to Mavericks.

Peruse the whole site. There is a lot of information there.

My external hard drive is 'seen' by my iMac and I can go into the Finder and open files and folders. I am using the hard drive for Time Machine back up. However Time Machine says it can't find the drive. Same thing has happened with Final Cut Express.

My new LaCie external hard drive is 'seen' by my iMac and I can go into the Finder and open files and folders. I am using the hard drive for Time Machine back up. However Time Machine says it can't find the drive.
The same thing happened recently between Final Cut Express and my other LaCie external hard drive used as the Scratch disk. It fixed itself.
I've run out of ideas. Help would be very much appreciated. Thanks.

have you done some searches on FCPx and time machine? Is there a known issue with using a TM drive with FCPx? dunno but ...wait...I'll take 60 sec for you cause I'm just that kind of guy.... google...." fcpx time machine problem" Frist page link

You cannot have time machine backups on your hard drive if you intend to use it in FCPX.
booya!

I dropped my external hard drive which contained my iTunes library and it is no longer readable. I attempted to upload my library from iPod and while all the songs appear to be in iTunes I get a message telling me that the original file can't be located.

I dropped my external hard drive that contained my iTues library and the disk is no longer readable. I figured I would simply transfer my music back from my iPod to my MacBook Pro and it loks like it worked. All the songs are there, but I receive a message that the original file can't be found when I try to play anything. ANy help would be greatly appreciated.

A Couple of questions..
Is the location shown under preferences/Advanced/General still showing the correct location?
Is the check boxes under this checked or unchecked?

I move folders from my internal hard drive twice to an external hard drive. Now I believe Lr does not know how to find my photos. What can I do to get this cleared up.

Jim has a very good suggestion. There are many factors at work here:
1) How are you connecting the external drive to the computer?
2) How big are files (329 x 1MB is not the same as 329 x 25MB)?
3) What is your computer specification?
4) Do you have any power saving settings on (in particular something that would send the computer/hard drives to sleep)?

I Mini with an i7 processor. I would like to use Boot Camp to install windows based CAD software on my MAC. Would it be better to use a plugin external hard drive to load my software on and if so what hard drive would you recommend?

Thank you for your quick response. I can then use a ZIP drive for data storage. I want to keep as much of my hard drive free of data as possible.

Can I view photos and movies from my external hard drive? I used Time Machine and a WD Passport for backup. Since my drive on my MacBook Pro is filling up I was planning to delete some of the movies and photos.

Hello, eco1.
Thank you for visiting Apple Support Communities.
This sounds like you are wanting to move your iTunes media folder to an external drive and have iTunes this folder from this location. If this is the case then I would recommend taking a look at the article below.

I wouldn't trust that backup.
Make sure the system is connected to AC and Do Over.

If I already have an Airport Express Base Station, can i hook an external hard drive into it's USB port and use that hard drive with Time Machine?

No, and that shouldn't be done with an AirPort Extreme or Time Capsule.
