Slow boot time Mac Osx when USB external hard drive is connected
I have bought some days ago an external hard drive, the Western Digital 500 GB Elements.
It goes very well by now but I have a problem.
When I turn on my MBP, after the "bong", I have to wait 60 second more than the normal boot time.
The screen stay grey and after 60 second it appears the apple.
It appens only when the external hdd is connected.
Someone has a solution?
Some time ago, I read that the OS has a problem waking from sleep or booting if an external was attached (USB or Firewire), something about it being confused about the startup order. Anyway, since then, I have religiously followed this procedure when I'm done using the external: unmount, unplug, and then turn it off (if necessary). I have never experienced a problem with my Mac not recognizing or not being able to boot because of an external. It certainly doesn't involve more than a second or two to unplug a USB drive.

Mac not recognizing USB external hard drive
My Mac OS X 10.5.8 isn't recognizing my Samsung USB external hard drive. The hard drive has already been formatted for a Mac (rather than PC). My computer has recognized the external hard drive before with no problems. I've used it on a campus computer to copy video files from a documentary I was filming, and I've also used it on another campus computer to copy video files from a multimedia piece. I still need these files, so having to erase my hard drive would be DEVASTATING. Now, my computer won't recognize my external hard drive, even when I have it plugged in before turning on my computer.
When I go to Disk Utility, my mac recognizes it, but when I try to repair and verify it says that it failed.
It's also not a problem with the external hard drive because I've plugged it into another computer and it is recognized on the other computer.
What should I do?When I go to Disk Utility, my mac recognizes it, but when I try to repair and verify it says that it failed.
Sounds like it's very badly damaged, and it may be too much to expect the data to still be intact. However, you can try repairing it with a more powerful utility, like [DiskWarrior|http://www.alsoft.com/DiskWarrior/index.html] or [TechTool Pro|http://www.micromat.com>. If neither of those can fix it, then your only options will be using a data recovery tool, such as [Data Rescue|http://www.prosofteng.com> or [File Salvage|http://subrosasoft.com/OSXSoftware/index.php?mainpage=product_info&productsid=1], or paying an expensive data recovery service to disassemble the drive and recover what they can.
Of course, this would all have been avoided if you had backups of your data. In the future, you must have a minimum of three copies of any data you don't want to lose. -

Why does my airbook mac freeze when using external hard drive
This is a recent development, my MacBook Air freezes when I attach my external CD drive and I have to do a hard restart (hold the power button till it turns off). This never use to happen. Any suggestions? Cheers!
Hi
Can anyone suggest what is happening and how to get around this? In worst case is there a way to move the files outside of imovie that will still allow them to be properly displayed within imovie?
I don't think that it can be done that way - BUT I KNOW that it can be very destructive
most probably end up as un-reparable.
The move of projects and events - works so much better in iMovie'09

When emptying my trash, I get "The operation can't be completed because you don't have permission to access some of the items." (I always have a hard drive connected and have just found out that if I disconnect the hard drive, none of that trash shows in the trash can....so there has to be some correlation with the hard drive. I have had my mac for a year, and never had this problem before though with the hard drive hooked up and all the trash being able to empty completely.) How can I get rid of the trash. FYI - I do not have the time machine hooked up, so I know that is not an issue. Thanks for any ideas to try!
Please look over XLab's Solving Trash Problems article for some hints. This is an excellent place to start.

QUESTION.
Hallo , my question is ;whenever I delete a photo and restore it through Time machine and Western digital external hard drive , I am able to restore the photo but not the titles and descriptions . Western Digital inform me that it isn't their external hard drive problem and suggest that it is an Apple software problem ?
I am using a Macbook 4.1 , with Mac OSX 10.5.8 . I photo 7.1.5 , last modifie4d 01/05/2010 -universal . Should I be upgrading Iphoto ?
I hope that someone is able to help in this matter , as i have to restore 12000 photos !
Thanking you in anticipation.
Alan from WigtonHallo Kieth ,
I am not quite ready to restore the full iphoto library , as I have days of work re - imputting titles,descriptions and enhancement . I hope that your suggestion works , as I use my Macbook basically to work with digital photography. Through time , I will need to delete my library to recover more disc space and I would hate to have to spend more time re - imputting titles and descriptions all over again .
Thanks for your interest and advice.
regards - Alan -
If I start up when my external hard drive is plugged in Mac doesn't boot up
If my external hard drive is connected to my MacBook when I turn it on, Mac OS X does not load. What can I do to make the computer load with my external hard drive attached?
Either use the startup key commands or use System Preferences>Startup Disk to select the external hard disk before you shut down.

How do i repair or recover data from a corrupt USB external hard drive that does not show up on my Mac desktop or disk utility?
Last night i was using my external hard drive, for some reason the folder just closed and i couldn't find it on my desktop.
After googling solutions, i found it in the disk utilities, i clicked on the 'repair' button many times, but it said the 'error...' message.
So i ejected it to try again, now when i connect the USB external hard drive it doesn't show up on my desktop or disk utilities.
I really just want to either repair or recover the data on it because it literally has everything (documents, work files, photos etc) on it,
I downloaded an application to recover my files but it needs the USB to at least show up.recognise it which mine doesn't.
I know i should've backed it up on another USB, this definitely teaches me for next time to back up all my files.
Are the files lost forever or can i recover them by going to a shop or using a software?Thank you for responding.
This might sound stupid since i'm not really knowledgeable with Macs,
but since all my files were moved from my mac computer to the external hard drive,
is it possible to recover those files through my Mac - like recovering deleted files? -
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. -
How to transfer photos from a MAC to a USB external storage drive?
How to transfer photos from a MAC to a USB external storage drive?
Just the Photos? Or the Library?
If it's the Library:
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.

Will Time Machine work with an external hard drive connected (via usb) to Airport Extreme?
Sorry, but this article is about 4 years old, and was printed based on preliminary information at the time.
The bottom line here is that Apple does not officially support Time Machine backups to a drive at the USB port of the AirPort Extreme.
If it works for you, great.
You might want to review the Apple Support documents below, which are far more recent than the article you reference:
http://docs.info.apple.com/article.html?path=Mac/10.6/en/15139.html
http://support.apple.com/kb/HT2038
It is supported.....
This is NOT correct. Please do not post false information on the forums. -
Should I get a 2.0 or 3.0 USB external hard drive for my 2011 Macbook Pro? I need it to be compatible with the USB ports of both a PC and a Mac. I was thinking of getting a Seagate becuase apparently it is compatible with both systems, but I want to know which would be a better investment.

I had to reformat my OSX 10.5.8 and I can't restore my emails from my time machine backup from an external hard drive - only the latest (post backup) time machine back ups are available to restore. Please can any help? I can find the mail folder in my libraries, but the Restore Button is grayed out
OSX treats the reformatted drive as a different one; it's the same as replacing it, and the old one is no longer connected.
See #E3 in Time Machine - Troubleshooting to see and restore from the "old" drive.
And, you may not want to restore via the Finder; see the blue box in #15 of Time Machine - Frequently Asked Questions. -
Will Time Machine Back up an External Hard Drive Attached to my Mac Pro?
Apple TV is GREAT, but it quickly filled up my hard drive. My thought is to take my folder that contains all of my personal files and put it on an 1TB external hard drive. I'd then "point" iTunes to where this new folder is. First, is that the right approach? Will that mess anything else up? Second, can I have Time Machine then back this external hard drive up? So, I'd like to have Time Machine back up my Mac HD and the external HD. If Time Machine won't do this, is there a good back up program for Macs that is very turnkey?
Thanks in advance!!!GregT wrote:

If the drive is formatted +Mac OS Extended,+ yes. While it's connected, go to TM Preferences > Options. If it's listed in the exclusion box, just select it and click the minus sign at the bottom.
If it's listed in gray, however, it's either formatted wrong or corrupted, and you can't remove the exclusion. -
