External Hard drive is randomly popping on and off

Hi. You guys are awesome by the way. We need to set up a tip system, where I can paypal something into an account for you... coffee cards or something, maybe itunes songs!
One of my external hard drives is randomly disconnecting and then reconnecting to the computer. It is a 1TB Lacie connected over FW800 thru a daisy chain. It is a video edit suite with LOTS of attachments - three FW drives, a FW deck, two monitors, my ipod, and so on...
Any thoughts? Need more info?
Thanks.
Nick

Does it happen when off the daisy chain and hooked directly to the FW 800 port? If you don't know, then try that.

Hi! I got movies on my external hard drive that are AVI kind and won't play on my macbook pro? need some help please!!

Hi! I got Movies on my external hard drive that are AVI kind and won't play on my macbook pro? When I start playing the movie a message pops up and says "a required codec is not available". I tried flip4mac, xvid, divx already and still not playing my video. need some help please!! thanks.

Although vlc mentioned above is a much more powerful and better player you could try installing Perian if you insist on using the quicktime player. It may supply the codec it needs.
Not sure why you wouldn't be able to play straight avi files though in quicktime.

I use an external hard drive for my Lightroom library and I notice that all the images shown on there are DNG. On my MAC hard drive I have images shown as NEF. I desperately need to free up space on my hard drive, can I safely delete these NEFs?

however, I do point out that obtaining an additional hard drive and not throwing anything away seems a preferable solution to me.
heidie22, dj_paige has a very good point there. I would not through away the NEF files; I would archive them to a external drive.
By the way, I am assuming that converting RAW files to DNG is a decision you have made and not an accident.

I would like to connect an external hard drive to my time machine and use it as a network drive to store itunes and iPhoto how do i do this

I have just purchased a new my book hard drive and would like to connect it to my time capsule and store my itunes and iphoto contentent there to free up space on my internal hard drive . Can this be done and what is the process?

I'd like to store my Aperture /IMovie Libraries on an external hard drive.
That is fine and recommended.. use the fastest disk you can afford.. ie Thunderbolt>USB3>FW800>USB2.
In addition, I'd like to partition the external hard drive so that Time Machine can use it to both back up my IMac and the external library drives.
Let me be clear.. you want to partition the one disk.. use it for TM and move your files to the external disk.. and then backup to the same disk.. You can do it.. but that is not a backup.. that is an experiment in how long you can get away with running files and backups on the same disk before you lose everything.. like Russian Roulette.. pull the trigger enough times and laws of probability will do you in.
You must have backups on a different disk .. otherwise it is pointless.
Can I set up a RAID 5 format for redundancy?
No.. you can buy special USB and Thunderbolt external drives that support RAID..
BUT that is still not a backup.. let me show why.. you make a silly move and corrupt your file in aperture.. it is not that rare.
Raid will corrupt all copies of the files.. it is replicated across all disks.
Delete a photo it is deleted across all disks.. you have no recovery.
Alway, always consider RAID system one disk.. backup onto another disk.. and if the photos or movies are at all important to you.. ie your family .. make another copy and store in a relatives house.. There is no such thing as too much redundancy.

I am running my first backup on Time Machine using a Seagate external hard drive with a thunderbolt adapter and cable. I have a MacBook Pro 2011. It is backing up 11GB, and is telling me it will take approx two days. Is this normal?

If you subscribed to iTunes match the songs are kept in icloud. If you didn't but you did save the actual iTunes library folder which should include the music, video, etc. you should be able to just drag this file back to your machine in the same place and when you open iTunes it will give you a chance to identify the iTunes library folder.
You can test this to find out if you saved the media files or not and don't need to attach your nano to do it.
You are correct that once you connect the nano it will clear the existing files from it and sync it with the new iTunes library.
If you don't have the media files i'm not sure if/how to get them back on a windows ipod. I have everything backed up regularly because of the horror stories I have seen & heard.

Can time capsule back up an external hard drive attached to my imac and the iMac internal Harddrive

Can time capsule back up an external hard drive attached to my imac and the iMac internal Harddrive

In addition to Kappy's comments, the external drive must be formatted in Mac OS Extended (Journaled) in order for Time Machine to be able to back it up.

Is it possible to use an external hard drive for time machine backup and also as a regular hard drive?

I am using an external drive in the exact way that you described. You just keep it plugged in to the computer when you want to access the movies and files. In order to put files on it, just go to finder open up the drive under devices and drag and drop files onto the drive. It is just like using a usb drive with a terabyte of space.

Hi!
I have a WD my book external hard drive plugged into my imac and I want to share it over my network with my apple tv. I went into system preferences > sharing, checked "file sharing" and added my external hard drive to the shared folder. So now it is listed in "shared folders" but under "users" everything is grayed out (it says "read and write" for "everyone" - but "read and write" is grayed out, and it doesn't let me add or subtract users). Now I can access all of the folders I shared from my imac except for the externalhard drive. What's going on?

Hi RRFS!,thanks for help.I forgot to tell that hard drive has 2 partitions 1:format :Mac OS Extended (Journaled) and that works properly,2:format:MS-DOS (FAT32) and when i "get info" for both :first has shering & permitions:You can read and write - with name and privilege, second has shaing & prermissions:You can read and write- without name and privilege

How to export photos from iPhoto to external hard drive keeping Events structure (files and titles)

Hello!
I’ve been looking for a Automator application that does this for quite a while now.
Basically I want to have an Automator application that saves a copy of my iPhoto pictures in a folder, inside Finder. Like a backup. Later on, I can save those “folders and files” on my external hard drive.
What I want it to do is this:
1) Export photos from a selected Album or Event on iPhoto. Using as title: “Event name” – “number” (I mean the number of the file: 1, 2, 3 …)
2) Save them in a folder in Finder that I want.
3) Organize the photos in different folders, the same way they are in iPhoto.
The idea I had, was that it would do this automatically every time I launch iPhoto, as if it was synchronizing the photos into that folder.
And then, every time I connect my hard drive, it copies these “real” folders into my hard drive.
Is that possible? If yes, could you help me creating it, or tell me how I can do so myself, or where to download something like it?
Thank you a lot! Kind regards,
xanacarfran2008

Is this waht you want to do?
It's built into the File Export function of iPhoto 9 (11). Select what every photos you want and use that option to put each photo in a folder with the Event title it came from as in this test of six randomly picked photos:

How can I use one external hard drive for both Time Machine and iPhoto Library?

I have been using a 1 TG LaCie external hard drive for Time Machine backups. My (older) Mac has 160 GB and is almost full. I would like to move my iPhoto Library to the external hard drive, but I've heard Time Machine doesn't share one space well. Should I
1. create another partition (but will this erase what I've already saved) with Disk Utility? *I am running Snow Leopard*
2. create another volume to use for iPhoto, and if so, should the two volumes be of equal size?
3. leave it with one partition and move the iPhoto Library to the same partition with Time Machine back ups?
I know I don't need the entire 1 TG for back up of 160 GBs. Please advise the best path to take. Thank you!

You are getting incorrect information from your ASP. If you look at drive specifications the heat generated is no different for high vs low capacity drives.
I have upgraded the internal drive in my iMac 2007 with a 3TB Hitachi drive without any heat issues or other problems.
Larger hard drives have higher density platters so to access any given amount data the drives travel a shorter distance. Higher capacity drives should therefore run cooler than lower density drives because the drive spends less time spinning to access data.

I bought an external hard drive in June (this yr) and it suddenly stopped appearing on the desktop. Disk Utility could see it. It wasn't the cord - now that I've tried that, the ext won't even turn on. I need that data off the drive BADLY! Help!!??

The drive stopped showing up consistently at first, then stopped all together. Disk Utilities could see it, verify it but not repair. I need it backed up. I took it to a local computer shop who tried a different cord. Nothing. When I got home, I read through several support forums dealing with this issue. One said I needed to zap my PRAM on my MacBook. I did so. Now the external won't even turn on! Any hope of getting the data off that drive? It is still under warranty but undoubtedly the firm will NOT attempt to back up the drive before issuing a new one. I downloaded something called TestDisk 6 that another forum suggested but no one offered any clue how to use it. I cannot figure the first thing to do with it! It appears to may be a Windows formatted program, anyway as most of the instructions end in the suffix .exe. I'm at a total loss...both personally as well as having already lost a complete week of business. Any suggestions would be appreciated but please note - I am NOT that computer literate. Just telling me to download something won't help me if I can't figure out what to do once it is downloaded. Also, taking this hard drive apart will void my warranty. Not that that is the biggest of my worries at this point but I wouldn't have the first clue anyway! I live in an area where we have something called Mac Authority in the mall and a Best Buy. Those are the only 2 connections to Mac-related stuff I have access to. Help!!! Please?

If your external drive does not have an independent power supply, you may wish to consider a couple of lower-cost options before tossing the drive. Bus-powered drives have no external power source and must get all their power from the computer. They can exceed the computer's USB energy budget.
Cheapest option:
1 Meter USB 2.0 A to 5 Pin Mini B Cable - Auxiliary USB "Y" Power Design for external hard drives.
This gets power from two of the computers USB porst sna can provide enough power to wake up an under-performaing bus-powered drive.
If you don't have enough ports to use this, try the next cheapest option:
Newer Technology 7 Port Hi-Speed USB 2.0 Hub with Power Adapter for Mac & PC
Such a hub has a an independent power supply to make up for wahat the comptuer fails to provide.

How do I install Lion on external hard drive? I have purchased and downloaded through App Store but do not know where the download is located so I can install.

I want to install Lion on an external hard drive. The OS was purchased and downloaded through the App Store but I do not know where the file is.

If you downloaded the installer it will be in your applications folder. Failing that use spotlight start typing Install and it should show up.
This is assuming you downloaded the installer from the app store, and didn't just install it onto your mac. If all you have done is install it on your mac. Go to your purchases Lion should show up. Then click download.
Here is the Support page for installing osx on an external drive.
OS X: Installing OS X on an external volume - Apple Support
Hope this helps.
