I was finally able to resolve this issue. I went to LaCie's site and went to the support area to find troubleshooting steps for my particular drive. It turns out that the problem was corrected when I swapped the power supply cord of the "troubled" drive with another LaCie drive that I have and that seemed to resolve the problem. Thank you Tony for your help. I appreciate you guys!
Thanks,

Macbook no longer recognizes my lacie external drive

My macbook no longer recognizes my lacie external drive.

Use a data recovery product such as the ones listed here, and then get a replacement drive.

Need to boot new macbook pro (yosemite 10.10) with an external drive (snow leopard 10.6.8)

need to boot a new macbook pro (yosemite 10.10) with an external drive (snow leopard 10.6.8). Toshiba canvio 1TB, USB 3.0. Have formatted it for mac already. Actually works when chosen as the "boot drive" on my 2009? macpro desktop with snow leopard 10.6.8. OS. I still need to work from FCP 7.0.3 as we have many projects from the past that must be "re-edited" from time to time. The macbook pro sees the drive from the systems preferences as a "boot drive" but nothing happens when it is selected. Have also tried from start up, holding option key until drives appear for boot. Will only go as far as the grey screen with apple logo when selecting external drive.

Try using a virtual machine.
Parallels
VirtualBox
VM Fusion
Snow Leopard server for use with the above. Call 1-800-692-7753 and order part number MC588Z/A. Cost is $19.99 + sales tax and shipping.

I have the G Drive 1 TB (GEN4 1TB) external drive purchased in 2010. I need to connect to my new MacBook Pro. I'm using the external drive for media storage of my video editing projects. Will a 800fw to thunderbolt adapter cable work?

I have the G Drive 1 TB (GEN4 1TB) external drive purchased in 2010. I need to connect to my new MacBook Pro. I'm using the external drive for media storage of my video editing projects. Will a 800fw to thunderbolt adapter cable work? I understand that using a USB port connection is not fast enough for video editing. I read somewhere the G Drives don't connect well to MacBook Pro.
thanks

I doubt this can be relocated or moved so you might want to just repost in the macbook pro area.

Can you afford a new Thunderbolt case and cable? any case with FW800 is going to be slow 72MB/sec and less, and any new 1TB drive is capable of 75MB/s minimum up to 125MB/sec.
Thunderbolt storage can of course when setup properly reach 100's of MB higher using multiple drives.
Use what you have for a system backup or for secondary backup storage.
you might be able to take the drive - most cases allow you to open and swap drives - and use this:

I am using a Mac Book Pro. Now I am trying to read a LaCie 1 TB external hard disk. The MacBook Pro hangs while reading the LaCie external hard disk.

I am using a MacBook Pro. I have my movies stored on a Lacie 1 TB external USB harddrive. (42 Movies in HD - 538 Gb in use). When I try to read the LaCie external drive, my MacBook Pro is "hanging". Only a "hard reboot" helps to get my MacBook Pro up and running again. The MacBook Pro starts to read the drive, but half way he "stucks". I can read the LaCie drive without any problem om my windows machines, so the LaCie drive is O.K. Anyone familiar with this problem?

The drive is formatted NFTS, otherwise the drive can not handle large files under Windows. And yes, I can see the drive in Disk Utility.
I can even see the files (partly) untill my system is hanging.

Is Time Machine something that I can back up to in a separate particle of my new MacBook Pro or do I need an external drive to use with it?

.....ie we have Seagate external drives but both have Windows files on them, although plenty of room. Am I able to keep the Windows files on them and back up to them with Time Machine on new MacBook Pro? Don't understand....and not very clear. Thanks
Belinda

Belinda,
In order to use Time Machine the external volume must be formatted in Disk Utility as "Mac OS Extended (Journaled)". You can't use a drive that is formatted to be used for both a Mac and a Windows unit (exFAT, etc.). You should purchase a new external drive to use with Time Machine and never let your work go for over a week with hooking up to the TM drive and allow Time Machine to do it's thing.

Mac no longer 'recongises' my lacie external drive

Please please can someone help me. I have a 2.4 intel core 2 running 10.6.8 I have connected to and used a lacie external fdrive for a couple of years and now suddenly my mac does not recognise it - it doesnt show in finder. I've done all the usual things like unplugging everything, shut down and restarted but it still does not show up. My system has 500gb but is at max so I need topush some files onto the lacie.
I am at a loss.. please, does anyone know what I can do to fix it ?
Many thanks

You can also do some basic trouble shooting including switching cables, turning off the power on the EHD, then restarting your computer at the same time doing a SMC reset and then reconnect the EHD. If that doesn't work connect the EHD to another computer to see if it's the EHD or the computer.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

Macbook Pro not able to burn from External DVD drive

Hi there,
I just bought a Samsung SE-208DB external drive for my 2011 Macbook Pro 8,1 13inch and at first the drive was detected by my Macbook Pro and I was able ot burn a disk but now when I plug in the device, it powers on for a bit then powers off to were I can't eject the disk anymore.Then sometimes it works just fine. I am using an external USB hub with AC plug power so I am confident power to the USb isn't an issue. I just wanted to know are Macbook Pro known to have issues with external drives?
And for those wondering why I don't just use the internal DVD on my Macbook Pro, I replaced it with an SSD for dedicated Windows 7 operating system.
Any ideas on how to approached this problem? Should I just get another brand of external DVD drive. I know I can't get Apples as for some strange reason, Apple makes those only compatible with Macs that didn't come with DVD drives like the Macbook Air.
Thanks

Ok I solved it.
The problem is that the drive uses too much power from the usb port.
You can use one of those cables with on one end two usb plugs and on the other end a mini usb. Connect the coresponding usb for power to an iphone charger or any 5v/1amp charger.
Or you can do what I did. I used a usb hub. In one usb port I connected my iphone charger and the drive to another usb port on the hub.
I have just burned my first succesful disc.
Regards

I have an issue with time machine, it doesn't find the Lacie external driver it use to use. it is the same drive that I usaly use for time machine back ups. It is corectly plugged. What can I do ?

Hi,
I'm trying to back up my macbook with time machine on the Lacie external driver I usualy use for this, but today my computer doesn't find the driver. I haven't done back up in 6 month.
Today, the Lacie driver is pluged and running, but the computer just does'nt find it.
what shall I do ?

Some things to consider:
Is the drive mounted, i.e., visible via Finder and/or on the Desktop?
Is the drive still selected in System Preferences, Time Machine? If not, use the "Select Disk" button.
Is Time Machine still turned on (System Preferences, Time Machine)?
Can you see the drive (and mount it) using Disk Utility (in your Utilities folder)?

My macbook pro no longer detects my camera.

My macbook pro no longer detects my camera.
After downloading thousands of photos, my mac no longer sees my camera. Nothing has changed. I have tried restarting the mac, using fresh batteries, different usb ports. When I try to download photos, iphoto opens up on it’s own, but my camera does not show up. Neither does it show up in any finder window, or under disk utilities.

My macbook pro no longer connects to my TV with the mini dvi to hdmi adapter. A while ago the computer fell down and hit the cable. How can I tell if the computer is working ok. Doesn't show mirroring any more.

My macbook pro no longer connects to my TV with the mini dvi to hdmi adapter. A while ago the computer fell down and hit the cable. How can I tell if the computer is working ok. Doesn't show mirroring any more. Was working while watching a movie but when I pulled it out from the computer and put it back in the system would no longer mirrorr the screen on the TV.

The best option is an appointment at an Apple store genius bar. The evaluation will be for FREE!
Ciao.

My macbook pro no longer connects to my TV with the mini dvi to hdmi adapter. It was working fine now I cant get it to output to the Tv. Any ideas?

My Macbook pro no longer outputs to my vizio led tv. It was working fine now I cant get any picture. It just says no signal. It is not the hdmi or the adapter because it works fine with my other tv. Any ideas on how to resolve this would be greatly appreciated. Please be as specific as possible. Thanks. BTW--I am using the mini dvi to hdmi adapter in case that was unclear.

Since you say that the same connectors work on your other TV is suggests that the fault is not in the connectors but your Vizio TV. I would check the settings on the Vizio TV. Verify that is is set to receive HDMI input. Perhaps you or some one else has inadvertently changed them. Pressing the wrong buttons on a remote control device can do that. (I am assuming no changes were made in SYSTEM PREFERENCES>DISPLAYS)
Ciao.

My macbook pro no longer connects automatically to my wi-fi network

Does anyone know why or how to fix the fact that my macbook pro no longer automatically connects to my wi-fi network?

Delete all the preferred WiFi networks, and try making the current one the preferred network in your Airport Utility setup.
