I have an Acer external hard drive 500GB. Is it compatible with Apple MacBook Pro laptop?

There are only a handful or Hard Drive mechanism manufacturers left. Acer is not one of them, although they may make the enclosure (but probably not that either). So in essence you have a Brand-X enclosure with some sort of Hard Drive inside.
Most of those work fine once they are re-Initialized for use on the Mac. For me, I prefer to use the Re-purposing of a drive as an opportunity to re-write every block with Zeroes (which can take several hours but can be done in the background), assuring that every block is good.

My Western Digital external hard drive suddenly stopped showing up on my Macbook Pro and disappeared from Disk Utility. It works on a PC.

My Western Digital external hard drive suddenly stopped showing up on my macbook pro and it disappeared from disk utility. I have tried making invisible files visible but nothing has worked and my hard drive shows up on a PC but not my Mac anymore.

What is the manufacturer of the external and how old is it? Does it have its own AC power supply or is it USB bus powered?

Can I mount my external hard drive which will be compatible with both Mac and Windows?

Hello,
Can I mount my external hard drive which will be compatible with both Mac and Windows? If yes, then please let me know, because I intend to use my hard drive for both Windows and Mac, without losing any file.

Yes. By default, Mac OS X and Windows can read and write drives which are formatted as FAT32 or exFAT; NTFS drives aren't writable from Mac OS X without additional software.

What problems specifically? If you have a problem you should start your own thread and explain the problem in detail.
External USB devices including hard drives and DVD work fine on the new Macbook Pros.

External hard drive will not power up on my macbook pro

I have a 120GB external hard drive that uses a USB port and it use to power up and work but now it just makes a clicking noise and nothing is recognized. the hard drive works on every other computer even pc's. the light on the hard drive is on but does not power up. Can someone help? thanks

hello. thanks for the help. It did come with a usb cable that had two plugs on one end. I never used both because the cord was not long enough to attach to both. I didnt have this problem at first. It would start right up but now it will not start at all. It does have an option for external power supply. Do you think I messed up the usb ports in the computer? thanks again for your help.

All USB drives should be compatible hardware-wise. If the drive is formatted NTFS, then you can copy from it, but not write to it. If it is formatted FAT or exFAT, then you can both read and write.

What size external hard drive do i need to backup my macbook pro?

I know I need to backup my computer, especially since I have been experiencing some problems with it and will need to take it into a store to get looked at, but I do not know what size external hard drive I need to back my computer on.

Drives are so low in cost today, go for something that will meet your needs for a while...if you are going to use Time Machine, get a drive large enough that you can have a partition double the size of the internal drive for TM backups, and a partition you can use for more storage and work space.
A decent drive like the Mercury Elite Pro 2 TB drive OWC sells goes for less than $200 (US) now. Has a fast interface and is easy to setup.

Can I partition an external hard drive to run windows games on my Macbook Pro

I want to play windows games on steam but I am not sure if I want to partition my Macbooks hard drive. I heard you could partition external hard drives but didn't know if you could run games on that external hard drive. I have a lot of files on my computer and don't want to take time to move my files to the external hard drive, so can I buy the external hard drive and then partition it to run window games or do I have to partition my actual default hard drive?

Hi! If your macbook doesn't have a cd drive you need to have Windows 7 but an ISO image, you can't just copy the contents of the copy into a USB and expect it to work. There are many tutorials on internet on how to obtain an ISO image from an installation disc, for example: http://pcsupport.about.com/od/software-tools/a/create-iso-image-file.htm As for "just download Windows 7" (i suppose you mean free download) this is not the right place to ask, believe me. Try searching Windows 7 ISO on google, but be careful with what you download and form where, also you are going to download the Windows drivers from the Bootcamp program, try reading this manual to give yourself a better idea: http://manuals.info.apple.com/MANUALS/1000/MA1636/en_US/boot_camp_install-setup_ 10.8.pdf

What external hard drives for backup are compatible with Yosemite?

I have an early 2013 MBP Retina 15" and have installed Yosemite. I want to purchase an external hard drive for backup via Time Machine. I have read that Western Digital drives were associated with data loss with Mavericks; I do not know if that has been corrected. Has anyone backuped successfully on an external hard drive with Yosemite installed, and if so, can you let me and others know the brand and model. Many thanks.

Understood.
I don't receive any compensation for promoting any product from any computer, hard drive or computer peripheral manufacturer. I don't receive any compensation from any of those manufacturers or sellers for any reason. In fact I was not promoting any product, I was responding to the poster's query and was stating that I have observed the drives in use and working with the Mac OS.
My workplace is a consumer of these items and we buy and use thousands of PCs, Macs, WD and non-WD drives, and so forth. I was providing information about whether WD drives work with Macs running various operating systems. I don't promote any particular brand, we use many different ones here.

My external hard drive won't show up on my MacBook Pro

So, I'm trying to transfer my music from my PC to my MacBook Pro. I put all my music on an external hard drive, but for some reason when I plug it into my MacBook it won't show up on the desk top. I've already changed my preferences in Finder so that hard drives and disks will show on the desktop, but still nothing. I looked in utilities to see if the hard drive was there, and still nothing. The hard drive is a Toshiba and is fairly new, the light goes on when I plug it into my laptop, so I'm very confused. Can anyone help me with my predicament?

Check that the data cable is securely inserted at both ends.
Try a different cable.
If you're connecting the drive through a hub, connect it directly to a built-in port on the Mac.
If you're connecting it directly, try a different port.
Disconnect all other devices on the bus, or as many as possible.
Test the drive with another Mac. Test another drive with this Mac.
If the drive is bus-powered, but has an AC adapter, connect the adapter.
Boot into Recovery and launch Disk Utility. Is the drive recognized?
If the drive doesn't work under any of the above conditions, and if another drive does work with the same Mac, then the drive has failed. You may be able to salvage the mechanism by removing it from the enclosure and installing it in another one, or in a drive dock.

Hi all, My external hard drive does not show up on my MacBook Pro again. I've tried connecting it to another Mac desktop as well but doesn't work either. any suggestions on how to fix this?

Hi all, my external hardrive is no longer being recognized on my Macbook pro after I tried to transfer some documents from another Macbook( that used the Lion operating system) to mine. i'm currently using the Mac OS X 10.6.8. Any suggestions on how to fix this?

I suspect the drive got disconnected, somehow, on that other system and corrupted the drive because of the Disconnection.
Connect it to your system and open Disk Utility and see if the drive is even being seen. If it is all the data on is more then likely lost and it will need to be repartitioned and or just erased and reformatted.

WD 1TB not recognised on 13" macbook pro retina (late 2013) even though it is exFAT file structure. The same drive is recognised on iMac and an old Dell laptop. I also have a seagate 2TB external hard drive (powered) that is recognised by my macbook pro.

I just bought a late 2013 macbook pro retina 13" a few days ago. I am trying to transfer all my music from my old Dell laptop. I formatted by 1TB Western Digital MyPassport to exFAT to allow read and write on both operating systems. The 1TB WD My Passport is recognised by both my Dell and iMac but not my new macbook pro retina 13 (late 2013). My 1TB WD My Passport is USB 3.0 with USB 2.0 backward compatability. I also just bought a 2TB Seagate Desktop Backup Plus (which is powered) for backing up and extra file storage, THIS WORKS! I don't understand how this works on my macbook pro but my 1TB western digital my passport doesn't. PLEASE HELP!! I have done full formats as well (not quick ones) which take nearly 8 hours. PLEASE HELP

Is there a pattern to the time of day or other detail that may be
traced back to a OS X system cause of this odd phenomenon?
Are there any copies of system files on any of the attached USB
external drives? Any libraries, such as iTunes, iPhoto, etc?
Once the drives are indexed by Spotlight, are their permissions
ignored by the OS X? Content, if neutral, should not affect the
wake or sleep cycle; especially if they're ignored by the OS X.
Could there be a bad cable or other component? If so that would
be a difficult process of elimination to detect it. Usually replacing
most suspect components in the USB stream (external to Macs)
is a rote way to mechanically test that idea; & not 100% sure.
Does the equipment all have a good ground to the utility or house
electrical field? An intermittent ground may affect more than sleep.
Hard to say at this point. Maybe a late-night talk radio guru on
remote viewing could peer into your situation and sleuth it out?
Sorry to have run out of ideas, but the process must be electrical
& mechanical to some extent. - Or perhaps odd software inspired.
Do you have any phone-home spyware items inside, just jumping
at the chance to spill your information? Little Snitch may help.
PS: Perhaps the computer needs to go into Apple & have a genius
or product specialist at AASP test the unit thoroughly... BlueTooth?

I have an external hard drive that I cannot find on my macbook pro.

I cannot find my external drive on my MacBook Pro. I can find it in the Utilities disk but I don't know what to do so that I can use it. Can you please help?
Thank you

Welcome to Apple Support Communities
To access to your external disk, open a Finder window and choose it in the sidebar, under "Devices". Another way is to go to Finder menu (on the menu bar) > Preferences > General, and mark "External drives" to show it in your desktop. Then, you can read your data on your external disk and you can copy files, unless your external drive is using NTFS. In this case, you will have to use Paragon NTFS or format it

My external hard drive is not recognized on my new MacBook Pro, even though it is recognized on my older MacBook and other computers. Help?

Please help me find a solution to my new MacBook Pro not recognizing my hard drives. Yes, thats two hard drives I have that don't seem to work on this computer but both work on my older MacBook and many other computers.

It is formatted for both PC and Mac
I have tried finding it in Disk Utility, no dice...
Tried both USB Ports
And a reboot is still unsuccessful..

I have a an external hard drive formatted for Windows, and I want to move those files to a new hard drive formatted for both Windows and OS. Is this possible?

I just purchased a MB Air 13", as well as a Seagate Slim Backup Plus. I have an older external hard drive that I was using with a Dell laptop. I would like to get the files off of the older external hard drive, and onto the new Seagate drive. Is this possible? I'd also like to be able to add files going forward to the Seagate from either a PC or a Mac and be able to view/use them on the MB Air 13".
Thanks in advance.

You will have to format the Seagate external HDD to a format common to both Mac and PC such as ExFAT. That should allow you to transfer files from the old HDD and still allow you to use with your MBA.
Ciao.
