My new mini won't recognize an external drive (LaCie 1TB porsche design)....any ides why?

Have a new Mac Mini, using an external drive but I can't get it to show up in finder. It's a Lacie 1TB Porsche design HDD, using a USB connection directly into the mini. I tried it at first by connecting to an open usb on my cinema display......no good. Also no good when connected directly into the mini. Any help would be appreciated!

Three questions.
1. Have you got Finder > Preferences set to show external disks?
2. Does it show/mount in Disk Utility (and if so have you verified it there)?
3. What format is it?

My macbook pro retina 13inch won't recognize my external drive (LaCie 1TB porsche design)

Hello,
I've had this drive for about 8 months and it's always worked fine. But when i connect it now to my macbook it won't show up anywhere, not with disk utility system profiler, nothing. However it does turn, i can hear and feel it spinning. Also when i connect to a windows it does show up. So I checked if it was the usbport of my macbook but when connecting my ipod there was no problem.
Any ideas?
Thx!!

Hello valleke92,
It sounds like you are unable to see your external HDD when you plug it in via USB. I would use the troubleshooting from the following article named:
USB and FireWire Quick Assist
http://support.apple.com/kb/ht1151
Check the connections
If you're using a cable, make sure that both ends of the cable are properly and securely connected to your device and Mac. Try unplugging your device and then plugging it back in. If you're connecting a FireWire device, make sure that the cable is no more than 15 feet (4.5 meters) long. If you're connecting a USB device, make sure that the cable is no more than 16 feet long. If you're making a direct connection, make sure that the device's connector is fully seated in your computer's port. If your device also connects to a power outlet, make sure it has power.
Check the system requirements
Check your device's documentation or packaging again, or go to the manufacturer's website, to verify that your Mac meets the minimum system requirements to use the device.
Check your device's power
If the device has a power switch, make sure it is on. Try turning your device off and then on again. Some devices require more power that the bus supplies. If your device came with an external power adapter, always connect it to a power source in for the best performance from your device.
Restart your Mac
Sometimes a simple restart can resolve issues. From the Apple menu, choose Restart to restart your computer. Once your Mac is finished starting up, test your device again.
Check the software
See if a newer version of software is available for your device if it requires software. Visit the product manufacturer's website.
Check your device's power
Make sure that your device is on if it has a power switch; try turning your device off and then on again.
Try a different port and cable
Connect your device to a different USB or FireWire port on your Mac. If you connected your device to a USB or FireWire hub or to a port on another USB or FireWire device that's connected to your Mac (known as daisy chaining), connect your device directly to a port on your computer. Some devices need to draw power from a USB or FireWire port to work; if you connect a device to a non-powered hub (one that isn't plugged in to a power source) or to a low-power port (such as the one on your USB keyboard), it may not work. If you have another known-good cable, try swapping the cable to see if that works. If it does, you should replace the problematic cable.
There is additional troubleshooting in the article if you need it, but it should all work you towards a resolution.
Thank you for using Apple Support Communities.

New Mini won't recognize Apple USB modem

I hate being thick but I can't figure out why my new mini won't recognize the Apple USB modem I just purchased. The network preferences see the built-in Airport card, Bluetooth, Ethernet and Firewire, but I cannot get it to recognize any kind of modem (internal or external).
I figured it might be an uninstalled component (this is the Mini with built-in Airport) and looked through the OS X installation discs, but no. I can't find any drivers on the Apple site for the modem... has anyone had any success with this?
Many thanks in advance,
m.
Mini / 1.42Ghz/airport Mac OS X (10.4.2)

Doh! Upgrading the system to 10.4.4 did the trick. I guess the right drivers for the USB modem weren't in the earlier version to be recognized.

Mac Mini won't read my external drive

Bought a Seagate 500GB external harddrive for my mac mini, and stored about 100GB of information in the harddrive. Now, the mini won't read the external harddrive. I am wondering if there is a way to retrieve it... Can someone help me? I don't think I can afford to loose 100GB of information.... Any help is greatly appreciated!

Clearly it has worked previously since you have data on it, but you haven't indicated what model of Mac mini you have (which can make a difference in terms of troubleshooting steps) and what circumstances surrounded the 'disappearance' of the drive - particularly as Boece says, whether it was disconnected (or powered down) without being first ejected from the desktop.
If the drive isn't being seen in the profiler, there is a possibility that the drive is not, in itself, faulty. A damaged cable, a faulty hub or a problem with the system's USB ports could be responsible. Since you don't give any detail about your system, it's hard to focus better on advising appropriate steps - however, if you are using a hub, remove it and connect the drive directly to the system, preferably using a different cable. If it mounts, then it was the cable or hub. If not, then open Disk Utility (in Applications>Utilities) and see if it appears in the drive list on the left.
If there's no hub and the cable checks out OK, then you might next perform a PMU reset (if it's a G4 mini) or SMC reset (if it's an Intel).
To reset the PMU for a G4 mini
- Unplug all cables from the computer, including the power cord.
- Wait 10 seconds.
- Plug in the power cord while simultaneously pressing and holding the power button on the back of the computer.
- Let go of the power button.
- Press the power button once more to start up your Mac mini.
To reset the SMC on an Intel mini:
-From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off).
-Unplug all cables from the computer, including the power cord and any display cables.
-Wait at least 15 seconds.
-Plug the power cord back in, making sure the power button is not being pressed at the time.
-Then reconnect your keyboard and mouse to the computer.
-Press the power button on the back to start up your computer.
If those steps don't help resolve the problem, post back with more information.

New songs and new audio book from Audible will not sync from my computer. Any idea why?

I updated my 4S to OS7. I am now unable to sync new songs and new audiobook from Audible from my computer. Any idea why?

Might be incompatible with iOS 7.
Keep in mind, Audible is not Apple software and Apple is not responsible for third party software compatibility.

New iMac won't recognize my external monitor.

I just upgraded my workplace computer to a late-2012 iMac (with the thin edges) from the previous older model.
I have an external monitor that I use as a secondary screen - a Samsung SyncMaster BX2440 - that worked great on my older machine using the DVI adapter.
When I plug the same adapter into my newer machine, it won't recongize the external monitor.
I tried resetting the PRAM, but no dice.
Is this a Thunderbolt issue, and if so, how easy is it to resolve? Do I just need to get a newer DVI adapter?

Loner: I looked at that and it only shows the main iMac display. Doesn't show the other device.
The model I'm using is a Thunderbolt machine (has the lightning bolt arrow icon). The previous machine was a DisplayPort model.
The adapter is the Apple-issued DVI adapter, but I'm guessing that even though TB and DP use the same physical plug interface, the adapters are not compatible?
(The adapter has the standard monitor icons on it - box with vertical lines on either side).

Unibody MacBook Pro won't recognize WD External Drive

I just upgraded from the old MacBook Pro to the earlier model unibody MacBook Pro. I had a WD external drive with firewire 400, and bought an expresscard adapter with firewire 400 so that I could connect to my new computer. the computer recognizes the adapter, but the drive will not power on or appear on the computer. It works fine with the old computer, though. Some help would be greatly appreciated. Thanks.

What version are you using with 10.8.5? Why did you import video into iPhoto? What are the complete specs of the video files? Are they in formats that are compatible with FCP?

What thunderbolt external drive - Lacie 1TB rugged or Buffalow ministration 1TB.

I want to replace my NAS as Time Machine back up for my 2011 MBA - it was unreliable and as traveling more too bulky. As my MBA only has USB 2 would like to use thunderbolt. Both of the main suppliers have issues - Lacie over heating and apparent failure, Buffalow poor support and almost no real info (e.g. partition / re format) on site? Any suggestions - has Lacie cured the overheating?

Hi,
The drive is USB 2 & 3 only. It spins up and does not make sounds like its faulty. The output is:

Need help now!

Do you remeber the exact (or close to it) wording of the error message?
Try manually placing the iPod in Recovery mode and then try to restore
Next try DFU mode.

New computer won't recognize external drive[s]

Just got an HP Pavilion 500t Desktop with Windows 7. Although the USB ports (front and back) WILL recognize an 8 Gig thumb drive, we cannot get it to recognize other external drives. We've tried our old Maxtor 3200 drive (which has all the files from the previous computer) and also a 1 T passport drive that I brought home from work.
What is up with this? I'm looking for some suggestions, please.
Thanks

It appears the Maxtor 3200 has an external power supply. Is the drive showing response to the power pack before plugging into the USB port? Same for the other drive?
When you state "we cannot get it to recognize other external drives" does that mean the computer does nothing when either one is plugged into the USB port?

My notebook won't recognize my external hard drive

Disable Time Machine from System Preferences.
Choose Select disk button, remove the old TM backup disk and add the new one.

My mac won't recognize an external monitor. The screen Goes Blue Once, then goes blue again and the second monitor just turns off. I am using an HDMI adapter to a visio TV. I also have my xbox on the tv. Can anyone Help??

Lol, figured out the first part. Just for those who may be searching, when you click on the Display Preferences, and click on the arraingment tab... it not only shows where your two screens will be displayed, but the WHITE BAR at the top of one screen is the dock/toolbar. Click and hold to grab this and just slide it over to the screen you'd like it to be on.
You have to release it IN the screen box, not on top of it... and it should pop right over to the new (or old) screen. At any rate, you can put the dock on either (or any) screen that you prefer.
I am thinking of ordering more of these. Lol. 3 monitor setup seems like it would be crazy good.
Still looking for the answer to keeping the new 16" screen on the right without switching between screen #s with that... not expose... Lion feature.
Thanks. Hope my other question has an answer out here.

OSX 10.9.5 won't recognize an external hardrive

I got a new Macbook Air running 10.9.5 that simply won't recognize my external hard drive.... I even tried formatting it with another Macbook Pro not running the latest OSX version. And another device (Smart TV) also recognizes the hard drive so I don't think that's the issue. I also opened disc utility to check whether it would be visible but it's not appearing there either...
Help please!

Thank you so much!!! This worked for me. I went file>new>library. Then I created a new project in that library, went back to the project in the old library that wouldn't export, I highlighted all of the clips in the timeline and hit cmd-c (copy), then headed back to my new project in new library and pasted the clips there. Then when I hit Share Master File it actually worked! The window popped up as usual and I was able to export. Thank-you Thank-you Thank-you!
