Macbook Pro will not recognize my external hard drive
I just updated to a newer MacBook Pro. I ran Time Machine on my old Macbook from a 2TB external USB hard drive. When I hooked the hard drive to my new Mac, it wouldn't allow me to select it as the drive for Time Machine. So I dismounted the hard drive and hooked it back to my old macbook to see if it still registered there (which it did). Now when I try and hook the hard drive to my new macbook, it will not recognize it at all. First question, why will it not recognize my new macbook, and second question, why does Time Machine not recognize the hard drive? It has my old time machine files on it...hopefully I don't have to reformat it and lose all my backup??
My hard drive is now connected. But Time Machine will not let me select the hard drive as my back up drive. This hard drive was used on another Macbook, so Time Machine doesn't seem to recognize the hard drive on the new one. Do I need to reformat the hard drive? I hate to do that because I have the previous backups on there.

My MacBook Pro is not recognizing my external hard drive. The hard drive is listed in disk utilities but an icon does not pop up and I cannot access the data. Is there any way to resolve this?
WE know Disk Warrior is more reliable, hence more useful, and should be in any disk mechanics toolchest.
For the record, I don't know anything of the kind. I have yet to see evidence that Disk Warrior is useful at all.
What I do know is that you seem to take every opportunity you get to promote it in these forums. Do you work for Alsoft?
Let me be a little more explicit. My opinion is that Disk Warrior is a waste of money if one has backups. If a journaled HFS directory is so badly corrupted that it can't be repaired by Disk Utility, then the volume should be reformatted and restored from backup, which has the same effect as running DW, but is probably faster and doesn't cost $99. -
Disk utility & TechTool Pro will not recognize volumes on hard drive
My Powerbook G4 will not start up. This is what happens:
1. Startup chime
2. Hard drive starts to make a constant 'pause-click, pause-click' like a skipping vinyl record sound
3. Then I only get as far as the flashing question mark on screen
I have disconnected all peripherals. I have booted up from install CD and used *Disk Utility* and it does not recognize the hard drive, only the CDR drive. I have booted from the Apple Hardware Test CD. All hardware passes. I have booted off the *TechTool Pro CD* and tried to run the entire suite of diagnositc tests. All hardware passes, all drives pass, but when I get to Volumes and Files, none are recognized. I have tried to get to the *Startup Manager*, but I can't get to that point either, only as far as the flashing question mark. I would like to be able to salvage data from the harddrive, so haven't tried to reinstall software and OS.
It seems to me that the hard drive is probably dead and I probably need to replace it, but is there any hope to recover data from the old hard drive
Any suggestions on what else I might try or on confirming my tentative diagnosis, would be greatly appreciated. ThanksThanks for the quick reply Tom,
I mostly save my work related documents on external flash drives or zip drive media, so my most important data for the most part is backed up. However, I had gotten a bit unattentive with personal interest stuff, like photos, music etc. I'll probably think of something important months from now and realize it was only on that drive, but for now I am most concerned about my downloaded emails and email addressbook. I never thought to back those up. Makes me want to stop running Thunderbird and keep all my emails online. Anyway I have some recent business inquiry emails from new contacts that are stuck on that drive. Can't recall the exact name of the organization this person was with. Aghh.
Think there is any use trying one of those data recovery programs to see if I could extract some information from the disk?
I am realizing that I will probably need a new hard drive to get the computer running . A friend's dad who is a computer teacher (though mostly PC but has kids with Macs so he's been working with Macs a bit and learning) mentioned the possibility of putting in a new hard drive as the start up drive then installing the old one as a secondary hard drive so I can try to access my data that way. Think that sounds like a feasible option to try? Perhaps I could run the recovery within that configuration. Worth a try? Pointless?
I appreciate any words of wisdom or commiseration.
Thanks,

Final Cut Pro Does Not Recognize New External Hard Drive
I am editing a large video project and I had to buy an external hard drive. When I go into FCP, it does not recognize that I now have a lot more room to store media. How do I get it to recognize. Please help! Thanks.
I can see the new disk on my desktop. What do I change in "Preferences" exactly?
In Final Cut pro - System Settings - Shift Q...
You can add it to your list of scratch disks... (which, BTW, should NOT include your system disk)

My MacBook pro does not see my external hard drive
I have an external hard drive La Cie (Porsche 250 gb).
Once I disconected it incorrectly.
Since that time it doesen't work
More specifically when I try to work with the hard drive the following message appears:
'Eject; Initialize or ignore'
I also tried to verify the disk with 'Disk Utility' but it doesn't work
Does someone know how I could access to the disk without formatting it?
Thank you
LorenzoI also tried to verify the disk with 'Disk Utility' but it doesn't work
I assume that mean your can "see" the external from DU? Normally, if DU can see the disk but can't repair it, you'll need something stronger like DiskWarrior. DW's strength is in recovering and rebuilding directories, the cause of most drive problems.

MacBook Pro no longer recognizes USB external hard drives or built-in iSight
I have an older MacBook Pro 17" Intel that I use with various external USB hard drives (8 of them). It is connected to my LG 720p 32" flatscreen and works perfectly. Recently, when visiting, I disconnected my external HDs and connected my MBP to my brother's LG 1080p and it was OK.
When I returned home and reconnected my external HDs and TV, it would not recognize the HDs and couldn't find my built-in iSight. Viewing System Information, the USB buses showed an assortment of items, such as the Apple Internal Keyboard/Trackpad, IR Receiver, and Bluetooth USB Host Controller in the buses. The High-Speed Bus showed an external HD as a Vendor-Specific Device, but none of these appeared on the desktop. I plugged in my external iSight to Firewire and it showed up in Photobooth, iChat, and Skype.
What is the problem and can I fix it myself or must I take it to be serviced?
Has anyone encountered the same problem? Got any answers?
I really would appreciate all the help I can get. Thanks.I have never heard of this before, but the fact that your external iSight works shows that at least some parts of your Macv's AV circuitry are undamaged.
Depending on exactly how you "disconnected" your "external HDs and connected" your "MBP to" your "brother's LG 1080p", I suppose it is possible that your software settings have been compromised somehow. Here is what I would try if my system showed the symptoms you describe.
(0) Start by making a current backup if you do not already have one.
Then try any of the following you have not already considered or used. Use them in any order you think appropriate and test after each one to determine if the problem is resolved:
(1) Shut down (do not merely restart) your MBP. Wait a couple of minutes before starting.
(2) Test in a different user (NOT the "Guest") account: http://docs.info.apple.com/article.html?path=Mac/10.7/en/mtusr001.html
(3) Reset SMC http://support.apple.com/kb/HT3964
(4) Reset PRAM: http://docs.info.apple.com/article.html?path=Mac/10.7/en/mh26871.html
(5) Repair your startup disk: http://docs.info.apple.com/article.html?path=Mac/10.7/en/mchlp1718.html
(6) Reinstall Lion and apply the 10.7.2 Combo Update: http://support.apple.com/kb/DL1459
(7) Contact Apple or an Apple-Authorized Service Provider for service

MacBook Pro will not boot - have replaced hard drive and problem persists
Macbook Pro Mid 2010
4gb ram, 2.4 GHz Intel core 2 duo
Originally when I received a folder with a flashing question mark upon startup, I assumed I had a failed hard drive. I went ahead and installed a new 500GB hard drive in my machine and installed OS X Snow Leopard. I upgraded to OS X Mavericks, and I had everything running properly. The next day, I went to startup and my Mac would not boot again. The dreaded folder and question mark were back.
I'm wondering what else could be causing this problem? Is it something I can diagnose and repair myself or will I be better off taking it into someone at this point?
Thank you!You can try replacing the hard drive cable...
Have you tried resetting the PRAM and SMC?
Does the hard drive boot when connected externally? -
I've reset SMC and PRAM several times. Activiatng Terminal from Recovery HD displays the following:
-bash-3.2# diskutil list

Any comments are greatly appreciated.Applejack is just a command-line "front-end" for a number of different command-line tools you can use in single-user mode, and I'm not sure whether it's Lion-compatible. You can always try booting into single-user mode and executing:
/sbin/fsck -fy
That's unlikely to solve your problems, though. Since you can't boot from two different hard drives and your optical drive, that indicates there's a more serious hardware issue, or multiple hardware issues. -
My Macbook Pro doesn't recognize my external hard drive
I had my external HD attached to my MBpro when I attempted to empty trash. The trash window showed it emptying thousand upon thousands of files (way more than was in the bin) and had a negative sign in front of the number of items being deleted. I canceled the emptying, but now the computer won't recognize the HD. It appears in Disk utility but not in desktop or sidebar. What happened and how do I fix it?
In Disk Utility, try using the Mount button in the top menu.
Disconnect the external drive, turn it off, wait about 1 minute, reconnect, and turn it back on. While waiting, restart the computer.

Hi cterry66,
Welcome to the Apple Support Communities!
I understand you would like to reset the user account password on your computer but do not know the original password. If you set up your Apple ID with that user account, you can use that Apple ID to reset your OS X user password. Please use the information provided in the attached article to complete the process.

Details help - is this trying to sent email? What version of iPhoto? Of the OS?
The general answer is
in the iPhoto preferences ==> accounts delete your e-mail account and reenter it
OR
IMHO the better solution is to set Apple mail as the email client in the iPhoto preferences

Since I installed the last Mavericks update, OS 10.9.2, my MacBook Pro will not recognize my Nook ebook reader. Maybe it's a coincidence; maybe not. Any ideas?
Check the Barnes & Noble or Nook websites to see if there are any Nook driver or software updates for OS X Mavericks.

My 2010 13" MacBook Pro will not recognize or start a DVD or a utility CD or boot up from either TechTools Pro or DiskWarrior. I tried to just install these on the computer with the computer running and it will do the same. When pressing the C key to start from the disc, it still does not accept it. It will cycle several times then reject disc.
It will play a music CD.
OS 10.6.8
CD/DVD Player.
Ideas?
Thanks,
FijimThanks for the reply!
I had set up an appointment at my local Apple store previously so they could reinstall Mavericks, so I just went in a little early, showed them the error message, and they determined that it just needed to be reformatted. I didn't have anything on there that I needed, since I hadn't accessed it for a few years, so we wiped the drive, reformatted and now I have my back-up.
I appreciate the suggestions
