Can my USB Drive be configured to power off when the iMac is powered off?

I am using a Lacie 500GB external USB drive. The drive remains powered on when my iMac is powered off. Is there any way to have the drive automatically power off?

Hello Jack
The s.o.p. for shutdown should be to eject the drive, turn it off then shutdown the iMac. The s.o.p for startup should be to startup the iMac then turn on the external HD. Many external HD manufactures do support a sleep function that allows the drive to sleep when the iMac is sleeping.

Can you charge a macbook by any other means than the power cord? For example the usb drive? My cord works fine but the outlet on the laptop is not.

The only way to charge a MBP is with a MagSafe power supply (wall or airline) try http://support.apple.com/kb/TS1713

Same thing just happened to my Mini, my wife successfully used a SanDisk Micromate adapter to download photos, but when she tried to plug in her iPhone4 the dreaded USB drawing too much power ports will be shutdown msg appeared. I can plug in the phone on my other Mac no problem, so its the Mini's usb ports. Help anyone? SMC reset did not work.

Help!-wont charge- A USB driver has exceeded its power limits?!!?

my iPhone charged just fine for the past two months, and now it only charges sometimes.
I will plug it into the wall charger, and it will charge just fine, and then i'll go to charge it again sometime, and it just wont charge, so i tried to plug it into my macbook, and my imac, and they both said "a USB driver has exceeded its power limits, etc, etc." and so i tried my PC, and it gave me the same message. This has happened more than once, and eventually it just charges, but then the whole situation will repeat days later.
I've called apple over 3 times, and no one has helped me. so...
help??

First, try a different cable. It may be shorting out causing the USB port to overload. Especially since it happens on two computers.
If the cable is ok, try turning the iPhone off. This can be done by holding down the sleep and home buttons until the off slider appears. Then restart it.
If this doesn't help, take it to an Apple store for assistance.

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

FCP X does not recognize projects and events on USB drive after a time machine restore of the MBP macintosh disk

FCP X does not recognize projects and events on USB drive after a time machine restore of the MBP macintosh disk.
I upgraded from an i5 to an i7 15" MBP and restored my files using my time machine backup. All seemed to go ok, except I had to use the migration assistant because on the initial boot the MAC didn't recognize the backup database on the USB device. MAybe this is a hint.
Since when I start FCPX it too cannot finnd the project or event directories.
Before my upgrade, I had a choice of files either on the Macintosh disk or the 2TB USB disk.
Now only files on the Macintosh are accessible to FCPX. The USB drive is visible under events and project but it finds no projects or events.
Please help if you can.
Thanks
Barry

Thanks... alas no one has responded.
I think I have the structure that you are recommending.
I have a root level directory (Final Cut Events) with the files in them.
The puzzling thing is that it used to work before the migration!.
Anyway I'm going to move the contents to the root and see what happens.
On a slightly different note...
I also posted a question about CPU utilization. Can I ask a question or two?
While rendering a short clip, I noticed burst of disk activity when the render started (likely loading the media files into ram since I have about 4Gigs available, then almost no activity while the render is happening, then more disk activity when its done.
However the cpu activity is not as high as I would have expected since rendering requires a lot of cpu.
What is your experience? I know some render is done by the GPU, but in my older i5 the CPU was about 100%, now in my i7 its about 50%.
Please look at the attached utilization for CPU and disk activity.
Thanks for any thoughts... Barry

IMAC 24" screen went dead. Can I buy a mac compatible monitor and still use the IMAC hard drive?

IMAC 24" screen went dead. Can I buy a mac compatible monitor and still use the IMAC hard drive - which is still working? I took it to the Apple store and they quoted $500+to replace the monitor. No help as usual. Can I buy a MAC compatible monitor ($189) and use it as a primary monitor? Can I set it up if the screen on the IMAC is dead? Any other solutions?

The only negative to not having the original drive will be the work needed to reinstall all the apps and reconfigure to your liking. You will also have to decide whether to stay on Lion (which you should update to 10.7.4, BTW) or bite the bullet and take a leap of faith on Mountain Lion.
In either case, to simplify matters you would do well to concoct a Lion or ML bootable installer on a USB stick. In either case, you need to get the corresponding installer downloaded onto the hard drive and, instead of running it to execute the install, extract the coveted InstallESD.dmg image from which you construct the bootable installer. See here for details: https://discussions.apple.com/message/17782820#17782820 The procedure applies the same to both of the latest cat flavors.

My Macbook pro is rejecting my Iphone 5 charger. When ever I plug it in it says that the usb is taking to much power, yet when i plug in a different Iphone 5 charger it works fine. I'm just wondering why this is happening and how to fix it?

Do you actually mean the white cable with a lightning plug on one end and a USB on other
If so that is not the charger ,that is the cable
The charger is the device that plugs into the mains socket
If so
cable may be faulty if less than 12 months old take it to Apple Store genius bar for checking

You can sync your iPod with multiple computers, but what can be synced is very limited. See this article for more details.

If you type in finder search "Migration Assistant" you should be able to restore from TimeMachine backup.

How can i do a factory reset in snow leopard without the disk to start off new without losing my other programs

how can i do a factory reset on snow leopard without the disk to start off new without losing my programs?

You can't. You will need a Snow Leopard disc. You can purchase replacements for your computer from Apple:
Apple Store Customer Service at 1-800-676-2775 or visit online Help for more information.
To contact product and tech support: Apple - Support - Contact Apple Support.
A "factory reset" means you erase the drive securely. All of your files will be removed permanently. I suggest you make a backup:
Clone using Restore Option of Disk Utility
1. Open Disk Utility in the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Select the destination volume from the left side list and drag
it to the Destination entry field.
5. Select the source volume from the left side list and drag it to
the Source entry field.
6. Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.

Power consumption of the iMac 2007

Hello!
I found at this website: http://www.apple.com/environment/reports/ the reports also for older models of the iMac, but not for mine.
Can someone eventual tell me the power consumption of the iMac 2007 24" in standby- ond off-mode? Or is there an older report from Apple available somewhere?
Best Regards!

It's going to fall somewhere between the idle of 92W and the maximum of 310W. I would aim at around 210-230W.
I run mine on a APC 1500 pro which provides about 15 minutes at 400W. I have other devices on it as well.
I would think at a minimum something like below. This would only provide about 8 Minutes at 300W

Another option if you have access to a second Mac with a drive is to connect the two together with the iMac in Target Disk Mode, Transferring files between two computers using FireWire, and installing from the Mac with the optical drive.
