Macbook telling me that my external hard drive with a usb is pulling too much power and has been dialed what do I do
I have been using my Seagate Free Agent 500g external hard drive for years without even a hint of a glitch but this morning I trying plugging in the usb and got an error message that stated that the hard drive was pulling too much power and was being diabled. So now I cannot get the hard drive to connect period. What do I do - could it be a power cord issue?
Hi cactus flower,
If you are getting a message that a USB device such as your external hard drive is drawing too much power, there are a number of things you can do. I would suggest the steps in this article -
Apple Computers and Displays: Powering peripherals through USB
http://support.apple.com/kb/HT4049
Specifically this section -
Troubleshooting
If you have a peripheral (such as a hard drive, audio device, or camera) that is acting unexpectedly—such as not turning on or not being recognized by the computer—the peripheral may require more power than is available. If you have a USB peripheral or a chain of devices, such as a joystick plugged into a keyboard, which requires more than the available power try one of these options:
Use a USB hub that comes with a power adapter.
Check that the peripheral offers the ability to connect to more than one USB port at once.
Find out if the peripheral comes with a power adapter.
If you cannot confirm your device's use with a hub, connect the device directly to the Apple computer.
Thanks for using Apple Support Communities.
Best,
Brett L

just got Prosoft drive genius 3 software, and it's telling me that the external hard drive that i am using for my time machine back up drive needs to be defragmented. is it wise to do this or should i not??
Let's hope a couple things: that you have bootable clones of your drives also; that the backup drive for TimeMachine has over 3x capacity of the data you plan and are storing. I would also switch TM backup drives so you have a 2nd.
Fragmented free space affecting performance happens when the drive is too full which may mean there isn't enough free space for a full backup set.
1.5TB for backing up 500GB, while WD Green 3TB is $140 and WD Black 1.5TB is, about the same price.
I'd be worried about the integrity and directory, and whether you can afford to lose that drive. Defragging is also a very slow operation. the ideal: to just clone a drive, or start over with another drive and wait. cloning TM volumes has not been done or has it? SuperDuper hoped to but I don't think they or Bombich's CCC made it there.
Trouble with highly fragged is when free space gets to 20% normally, 1/3 or so though for TM volumes, and finding where and a chunk of space for the file being written. Does TM use large spare image files of like 2GB?
Best would be to ask in the TimeMachine section Snow Leopard

Hi, all.
Two days ago I was using my computer, a 2011 Macbook Pro, and suddenly got the error message reading "Your Mac OS X startup disk has no more space available for application memory. To avoid problems with your computer, quit any applications you are not using. Closing windows and removing files from your startup disk will also help."
I was only using Google Chrome, nothing was running in the background, and I have 443 of 449.25 GB available (this is after clean-up I conducted after receiving the error message, but probably cleaned up less than 25 GB), so there should be no shortage of space. However, the message kept popping up and I deleted a few files and eventually it went away and hasn't reappeared.
However, last night and then again this morning I have been getting the error message that my USB drive is pulling too much power and has been disable. All that was plugged in was my iPhone 5 on the charger and my computer is also on its charger, so I don't know why this would be an issue, either. I have always charged my phone this way and never had a problem until today.
I haven't been able to charge my phone since. What's going on with my computer?Regarding the USB, see if zapping the PRAM helps.

How can i use external hard drive with mac and pc!
I've been using a Lacie external hard drive with my mac to keep the itunes library and other things since day one. Since i have a dvd with files for windows and an old pc without a dvd drive, i decided to copy and paste the content of the dvd to the external hard drive. The only problem now is that when i plug the external hard drive to pc, it won't open. I know it has to be formatted in a different way, but i need to find out the best solution!
Any idea?You can format the external drive in Fat32 (which I don't recommend but is the most compatible between both platforms), or NTFS (which requires some work to get your Mac to recognize), or HFS+ (which requires special software on your PC so your PC can use it).
If you use this drive mostly with your Mac, get MacDrive for your PC:

If you use this drive mostly with your PC, here's some software for you Mac. I haven't tried this myself, but the professional reviews have been good:

I am running my first backup on Time Machine using a Seagate external hard drive with a thunderbolt adapter and cable. I have a MacBook Pro 2011. It is backing up 11GB, and is telling me it will take approx two days. Is this normal?

Re Time Machine
I have an external hard drive with files I backed up manually over the past 2 years 1TB of memory.
I am finally taking the leap to use Time machine to back everything.
will I have to reformat that drive, thus wiping my previous back ups?
can I split it the drive in two partitions?
Also
as I have two separate Macbook Pro's- one older than the other.
OSX 10.68
the other is
OSX 10.75
can I back them up separately?
or even synch and merge files and folders etc? between the two?You CAN use a drive with files already on it to store Time Machine backups. But long term, that is not recommended. You do not need to reformat or re-partition the drive to do this. Once Time Machine Backups are established, you could remove the old files.
But do not delete Time Machines files with the Finder -- that can cause it to lose its place and lose everything.
With the cost of backup drives under US$100, it might be a better idea in the long run to get another drive. Best results from Time Machine is a drive about 3 times larger than the drive(s) you are backing up. -
What is the best external hard drive with MacBook Pro
What is the best external hard drive with MacBook Pro?
I agree with Allan, and that link is also called OWC, their hard drives are great. Have three of their Mercury Pro Elite 2 TB quad interface drives. They will connect eSATA, Firewire 800 & 400, USB2, so broad reange of options. Drives seem to come Mac HFS formatted, but I always reformat and partition the drives. Service and quarantees are top notch.
They offer a wide range of drives/drive systems so like Allan said, spend some time seeing what the have. -
can this device be used as an external hard drive with a macbook pro laptop and use files on the airport time capsule?
If you mean an AirPort base station other than the Time Capsule, it doesn't have internal storage.
If you mean a Time Capsule, its internal drive can be used for regular file storage but shouldn't be; as with all drives, it'll eventually fail. You're better off using a standalone drive and setting Time Machine to back it up as well.

After I installed Lion, my MacBook Pro can no longer detect my external hard drives or my USB flash drives. What should I do?
And me -- My Mac at work running Snow Leopard reads the drive normally. My home Mac (on Lion) can't even find it....
Yet another Leo let-down..... -
Since I upgraded to 10.9.5, my macbook no longer recognizes my external hard drive. How do I fix this? External hard drive is a 1TB Toshiba formatted for mac. Worked fine until latest upgrade.
Solved the problem by dumping my external HD onto another computer. Re-formatting and re-installing the data. Not what I wanted to do but it solved the problem.

Is there any way to create a time machine backup to an external hard drive with content already on it? I have a hard drive that i have used for pictures but when i try to run a backup it says i need to start from a blank drive. Can i get around it?
It would be much better if you had separate drives for the pictures and Time Machine backups.....but, if you want to use the same drive for both purposes, temporarily move the folder with the pictures to another location for safe storage.
Run the Time Machine backup on the hard drive and verify that everything is working correctly. Time Machine will format the disk for you in Mac OS Extended (Journaled) as part of the backup process.
Then move the folder with the pictures back to the hard drive with the Time Machine backups.
When you have tested to make sure that everything is working again, then and only then should you delete the folder with pictures from the temporary storage area.
Again....it would be much better to keep Time Machine backups on a drive just for that purpose, and other data on another drive for that purpose. This is clearly one of those times when the fact that you can do something does not mean to imply that you should do it. -
In disk utility, it shows that my external hard drive is somehow unmounted and I can't access it in finder or repair it in Disk Utility. How can I get this working without losing my important data?
Thank you!When you erased the disk did you select Mac OS Extended Journaled as the format option?

I have an external hard drive with numerous WMA files that I would like to download to iTunes. How do I do this on my MAC?
You can't write to it because it's formatted as NTFS which OS X will read but not write to. If you want to continue using the drive with both a PC and OS X you will need to download and install NTFS-3G so you can then write to it from your Mac. You can get NTFS-3G at:
http://www.macupdate.com/app/mac/24481/ntfs-3g
If you want to use the drive exclusively with your Mac then move the data off it and reformat it in Disk Utility (Applications - Utilities - Disk Utilities) as Mac OS Extended (Journaled.) -
Cannot access shared external hard drive with other mac accounts
I cannot access a shared external hard drive with other mac accounts (all accounts are on the same macbook Pro). The shared external drive is shared via time capsule and is connected (of course) in USB. I see well this external hard drive as a shared disk with my main account. Yes shared option has been activated with the Airport Utility .. but when I open other account these othe accounts can see the external drive but cannot access to its content that is flagged with a no way sign. Strangely enough when I close my main account and start opening a new session with one of the other account then fine I can access the external hard drive and its content .. BUT then it is from my main account than I cannot access its content the no way sign showing ..
Looks like only one account at a time can access the content of this SHARED external hard drive .. any one as an idea on how to really make it a shared hard drive so that all accounts on the same mac can also access it ? I am at my wit ends on this case. THANKS ..Results of my enquiries at Apple Genius Bar .. the guys found the problem interesting. They've been unable to provide a fix neither to give any explanation as to the reason why. To be fair I was not much impressed by the technical level demonstrated ..
In the mean time I have found that if account no.1 can see the shared external drive content and in such case account no.2 (same Mac computer) cannot see its content (only the external HD with a no way sign) this account no.2 can UNMOUNT (by ejecting) this external HD from account 1 and then remount it (just clicking on the TC shared part in a finder window) and .. see and access its content ; whilst account no.1 cannot see its content anylonger. Unless it unmounts the shared external HD and remount it .. then account no.2 can see its content anylonger. This can goes on an on.
So eventually YES the TC can allow to share a USB external drive between several accounts and a same Mac .. BUT this require to unmount and remount EACH time the external drive is accessed from a "no.2 account". So OK to share files with seldom access but not practical in case of frequent access needed.
I just I have now to figure how iTunes can automatically unmount and remount a shared external HD when it needs to access one of this shared HD content from on time account no.1 and then next time from account no.2. May be I am asking too much ..
