Computer not recognizing external harddrive

I just did a software update and now my macbook pro will not see my external hard drive

I hope it was not connected at the time you did that. It may help if you gave more (well, any, really) details.

HT201250 not recognizing external harddrive

I backed up my iMac with a terrabyte external harddrive..June was the last time it did the back up and when I try to set up time machine it does not recognize my harddrive or even being plgged in my computer. HELP

Do you have Finder Preferences set up to show hard drives in the sidebar? If so, does it appear there?
If you haven't used the external hard drive since last June, try shutting it down, wait for about 30 seconds, and then turn it back on. Every time we experience an electrical interruption, I have 2 external hard drives I have to reset.
I strongly suggest you backup more often. You could lose a lot of files which you couldn't replace if something went wrong.

I have many photos on my computer. I have backed up the computer to an external harddrive. When I go into the external harddrive, how do I find the many albums I have stored/created in my iphoto library?

You can't view your photos in the iPhoto library in Time Machine vis the Finder. You must enter Time Machine, go back in time to the library you want to restore and restore it?
One can only restore an entire library from TM:

My computer ignores my external harddrive

alright, so i accidentally started to unstuff a .sit file onto my external harddrive and my computer froze, so i had to restart my computer. When it rebooted it said that there was an error with my hard drive and asked me what i wanted to do. I chose ignore, not knowing that it would ignore it forever. Is there any way to get my computer to quit ignoring it, and recognize when i have the hard drive plugged in. The hard drive is a maxtor one touch usb 2.0.

I can't do that because the hard drive won't mount, so it won't even show up in disk utility. I did an experiment and plugged in the HD to a pc and the pc recognized it, but i couldn't open it unless i formatted the drive. I'm going to bring it to work and see if i can get results on my mac at work. i'll post the results.

Maverick does not see External Harddrive

I had a Seagate external usb3 harddrive connected. I was working on a video file when suddenly I got a message in the upper right hand corner saying that the external harddrive was incorrectly disconnected or dismounted. OK. So, I unplug and then plug the ext. HD back into the usb3 port. To make the story short, the hd light comes on, I can hear the disk spinning. But it does not appear in the Finder or desktop. The only sign on the Mac is by going to the "About This Mac" and to the System Report which lists hardware and software. Clicking on the USB line, it shows the external HD plugged into one of the usb 3 ports. The disk info indicates its ID and other data and how much energy it is consuming (it appears it is only using 96 mA from an available 500 mA). So, it appears that the Mac sees it and can read it and has power enough to run it.
I then removed the first ext. HD and inserted another Seagate external usb3 harddrive - the Mac doesn't see it either except in the System report. The external HDs do not show up in the Disk Utility app. The only conclusion is that the harddrives are probably OK but the Mac won't mount them anymore. Most people with unmountable ext. HDs usually see them in the disk utility (greyed out).
Any ideas.

Update - I have three Seagate FreeAgent GoFlex external harddrives. The two that I have connected to my Macbook Pro no longer can be read. I took the two and connected to another MacBook Pro but it would not read the drivers either. I took my third drive which I have not connected to my Macbook Pro for several weeks and connected to the other Macbook Pro and it reads it fine.
I downloaded drivers from Seagate but it didn't help. I started my computer in safe mode, HD didn't work. I have another drive containing a duplicate of my internal HD (using Superduper) and booted with the backup drive. It would not open the two drives. I'm taking the HD to a friend who has a G5 using an early Mac OS, 6.0. These two drives contain my video files and I need to retrieve the files.
Conclusion: The Maverick on my computer has corrupted the first two Seagate drives.

Powerbook G4 is not recognizing external HD

Hi. My computer is dying. I can feel it. It's doing all these weird things it never used to do, like suddenly lapse in to a grey screen where I can do nothing but restart it in order to get it working again. I have about 60 gigs worth of music and pictures that I absolutely must back up. The problem is, some time in the last 6 - 8 months, my computer suddenly stopped recognizing external HD devices. I've tried it with three separate devices now. The first two were loaners but this last one I bought. I know I meet the system requirements, and I can't think of any reason why this would be happening. I've tried 3 different devices, which rules out the problem lying with the devices. My computer used to recognize external HD's just fine. I have no idea why it stopped.
Two things worth mentioning: My battery is dead. Someone stole my battery and replaced it with a dead one, so my laptop is no longer portable. But it shouldn't be an issue of the device not receiving enough power because the computer is plugged in.
The light on the device is not a solid green; it's blinking with orange, and the device keeps making a faint clicking sound.
Any help would be much appreciated. If I can't figure out the problem here I'm going to have to take my computer to the apple store and that's always a hassle.
Thanks

Oh my ....
First, if you have the original OS X disks that came with the system, insert the first one (should say in small print on the label 'AHT Version x.x'), reboot, holding the alt/option key down, and choose the Apple hardware test, and when prompted, choose the extended test. If you have either of the TechTool programs, they can do similar testing. Does that point out any hardware issues?
Faint clicking normally suggests a hard drive about to die. You could always download Smart Utility from http://www.volitans-software.com/smart_utility.phps to get a readout of your SMART sensors. If you're hard drive is 3-5 years old, it may be on it's way out, and causing issues.
Have you reset the PMU? And while you're at it, might as well reset the PRAM. PMU reset is: http://support.apple.com/kb/HT1431 and PRAM reset is:
1. Shut down the computer.
2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
3. Turn on the computer.
4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
6. Release the keys.
After that, what the status?

Photoshop 11 does not recognize external harddrive when trying to reconnect images?

I have moved my catalog to a new computer, using Photoshop Elements 11. All images are on 2 external harddrives. The PC recognizes both harddrives and shows folder structure and files correctly. When in Photoshop Organiser the thumbnails appear, with the question mark, as the drive structure is different to the old PC. When trying to reconnect the images to the second external harddrive Photoshop suddenly does not recognise this harddrive anymore.
Please anybody advise on what I can do to fix that?

Please try steps mentioned on blog: http://psekb.blogspot.in/2013/03/how-do-i-reconnect-missing-files-in.html Let me know if it doesn't help.

New computer not recognizing iPod

My laptop hard-drive crashed, but I had all my iTunes on an external hard drive. My iPod (30GB, noncolor, flywheel) had been synching with the ailing laptop and was not working right (showing the folder/exclamation point sign; when I hard reset it now I just get the Apple symbol and clicking sounds), so I'm assuming my iPod problems are just a reflection of an aborted synch attempt with the dying compueter.
So now I've successfully reset iTunes on my work desktop PC with Windows XP via the external hard drive. I downloaded the latest iPod version onto the new computer but it is not "recognizing" my iPod...it says to plug in my iPod when it is already plugged in. The plugged in iPod seems to alternate between "Do Not Disconnect" and "OK to Disconnect" (with a giant checkmark) messages. Regardless, the iTunes page is not "recognizing" the iPod...
Once I do figure out how to get my iPod "recognized", should I choose to RESTORE or UPDATE it? I don't have playlists or ratings to worry about, just ~3500 preciously selected songs I enjoy shuffling at random.
Thanks!

I cannot "See" the iPod. I have tried it on different computers that worked before with my iPod. On a laptop computer, there is some humming and clicking as if it is about to be recognized, but my iPod never shows up on the iTunes list (under Library, playlists, etc). When I go to "My Computer", there is nothing listed under the appropriate E drive (USB port). On a desktop computer, the iPod actually changes to the "Do Not Disconnect" sign and again there is the expected humming and clicking that suggests it is going to be "recognized", but it never comes up on the iTunes list. Under My Computer, there is a transient picture of something like a hard-drive with a big red questionmark, as if the computer is in the process of "recognizing" something at the USB port, but this fades and then there is intermittently this "removable storage" listed under drive F. As if it is only transiently being "recognized". When I manage to right click on the transient icon under My Computer, I get the list pulled down and left click on "Format..." but nothing happens. Then the iPod screen changes from "Do Not DIsconnect" (which again was an improvement from the other computer where there was no sign the iPod was even attempting to engage with the computer) to the giant checkmark and "OK to Disconnect" sign OR goes back to the "File Folder/! icon". Tried several times....
What do you think?

Mbp not recognizing external display

I have a 2010 MBP 2.8 and I'm trying to connect to a 24" Samsung LCD display to use as a 2nd monitor.   I'm using the mini display to DVI. And plugging a DVI to HDMI cord to that.
When I plug it into the tv and computer. The screen on computer flashes blue a couple times then nothing happens.   The computer is not recognizing the display.    I'm running Mountian Lion obviously and theres no option in "Displays" in preferences.
Am I doing something wrong? I had a old Powerbook G4 that I did this with all the time with Leopard OS.    Whats changed?

Hey all, did a software update on my partner's mbp yesterday (10.5.8, security update 2009-006) and had the same thing happen where our external viewsonic display was no longer being detected. Plugging the cable in and out of the mini display port had the same effect already mentioned here where the mbp screen flashed blue like it was about to recognise the external display, but then nothing. Selecting detect displays from display preferences also had no effect. Tried resetting the PRAM and also the PMU, still nothing. So I shut down the mbp; disconnected the mini display cable; then turned off the viewsonic monitor at the power outlet and left it off for 10-20 seconds. Then I turned the viewsonic's power outlet back on, started up the mbp, turned the monitor on and plugged the mini display port cable in and the external display was back and working properly. Have shut down/restarted numerous times since then and it's all still working normally. Not quite sure how/why this busted in the first place, or why turning the viewsonic off at the power outlet seems to have fixed it, but it might be worth a shot for those experiencing similar problems... and it sure beats having to install/reinstall a different os version (which was going to be my next option)!

However, after your remove the Apple software components also remove the iCloud Control Panel via Windows Programs and Featurs appin the Window Control Panel. Then reinstall all the Apple software components
- New cable and different USB port
- Run this and see if the results help with determine the cause (after you do the above)

Computer not recognizing my built in iSight

my computer is not recognizing its camera. I have tried restarting, forcing restart, and holding keys that apple care has previously told me to hold. I checked in my system profile and it does not even show my build in isight. Does anyone have a trick that has worked for them before, or a special way to restart my computer that may fix the problem? i am leaving for europe soon and don't want to mail in my computer if i don't have to!

I have reset the PMU twice and have reset PRAM (holding down apple-option-p-r at startup),I have also repaired disk permissions on my startup disk.
I can get access to the built-in isight for photobooth and other apple applications but as soon as I try to enable it in VMWare Fusion it stops the VMWare machine (Windows Vista) from booting until I disconnect the iSight from VMWare.
The iSight then disappears from the available hardware in VMWare Fusion (so I cannot reconnect it in Fusion) and I cannot access the iSight in any Apple application.
I have Applecare... I think I'll see if I can get any help there.
