Intel Mac :: No Longer Recognize Time Machine External Drive?
Jun 26, 2012
2012 iMac running 10.7.4 (lion). I have an external hard drive that I use for Time Machine. It has been working fine. Today, I turned it on to run Time Machine and the computer does not see the hard drive. I used a different cord to connect it. Still did not work. I tested both cords with a different external drive and they worked. So it is not the cords. The hard drive is getting power from its separate power cord. The hard drive knows when it is hooked up because the motor in the hard drive revs up when I plug it into the computer. However, the computer does not see it on the desktop or in finder.
Info:
iMac, Mac OS X (10.7.2)

Hi all. Here's the deal. I have an Airport Extreme and and external 1 TB hard drive. When I first set up Time Machine on this set up a few years ago (partitioning the hard drive first) it worked great! After a few firmware "improvements" from Apple it no longer works. The computers cannot attach to the external drive via the Airport and when I force them to the Time Machine backups fail after about 15 minutes of backing up.
I'm considering buying a 1TB Time Capsule for our main router and my wife's MacBook backup (I'll just hard wire the old drive to my iMac) and using the older Airport as a WiFi repeater.
Problem is that I've read about all sorts of problems with the Time Capsules failing after about 18 months. So should I try the set up I'm considering or is there a fix for my current setup that I should try instead?

Using Migration Assistant, I'm trying to transfer back-up files (whole system) from my Western Digital, External HDD to a new-to-me iMac which I've just purchased used. The External HDD has all my files (hopefully!) from my recently stolen iMac. As you can imagine, the circumstances are a bit unexpected and unsettling.
I've followed Apple's instructions for using MA with an external drive, but get hung up like others before me when it comes time for my new (used) computer to locate the disc from which to transfer the files. I've read the replies to others who have posted with similar difficulties using Snow Leopard, but resolving the issue seems to be just out of reach. Â
Original computer is now unavailable (stolen); it last ran on Snow Leopard, 10.6.3 to 6.8.New computer is used, and also runs on 10.6.8.Both computers are iMac 2009, tho slightly different versions, if that has any bearing on things.I created a temporary account on my new-to-me computer to make the data transfer, so that there wouldn't be an accounts conflict, as others have suggested.Western Digital External HDD, "My Book, Studio Edition," 1TB. I'm using the FireWire 800 port on the iMac. If I need to erase the hard drive on my "new" computer, I'll need a little instruction and hand-holding on that one.Â

I have an iMac and send all my Time Machine backups to an Iomega 250gb external hard drive. Now Time Machine says the drive is full and cannot complete the back up- how can I delete some old back ups to make room for the latest one? And once I have room- restrict it to back up only once a week? I really want to use the drive for the music and photos- but fear not having a complete backup before i update to Mt. Lion.

I just did a clean install of Lion on my 2.16 GHz Intel Core Duo iMac. Before I did that, I made sure that everything was backed up on an external drive through Time Machine. Now I want to restore everything and when I enter Time Machine, all that is visible for back ups are those that were done after the clean install of Lion.Â
when I open the files on the external back up drive through Finder, I can still see all of the back ups that were completed, including the most recent that I want to use to restore my iMac. I am considering another clean install to start the process again.Â

I was trying to set up my Time Machine to an external hard drive. I didn't continue because it asked to "initialize" the hard drive which I had a lot of important things on.
I have another external hard drive I'd like to use but, my Time Machine has this error code of -43. What is this and how can I use my Time Machine on another external hard drive?

Tried unlocking and allowing myself to read and write. Nope. Tried holding down the option key. Nope.
This drive is no longer being used by time machine and I want to delete some files on it. Is there a way to do it without wiping the entire drive?

Since the recent update to the time machine software it has been taking about twice as long to complete each hourly backup.

My external hard drive (Iomega powered 1TB hard drive) that I had as the Time Machine target recently filled up - I have 500GB on 1TB iMac - yet TM showed 999GB. I removed this hard drive and installed a WD USB powered 1TB and this keeps disconnecting - suspect by iMac. TM on System Preferences will not allow me to select the hard drive - I have to remove and reconnect the USB lead to allow the iMac to see it

I have an external 500gb drive plugged into my brand new Time Capsule. The 500gb drive basically stores my entire library of music and my iTunes points to this external drive.
Is it possible to have time machine backup all information on the 500gb drive to the time capsule, so encase the external drive takes a dump, I don't loose my entire music library? Maybe time machine is already doing this, I am not sure.

As my 160N series Linksys router neither has gigabit ports, usb connector or dual band networking, I am looking for a replacement.
When it comes to Apple routers I am looking at 2 options - either the base station with an external USB drive or get a 1TB capsule with the buildt in drive and worries regarding reliability.
What I like about the Time Capsule is that it is neat to have all in one, takes up less space and only has 1 plug to attach, while Iike the idea that I can just connect a bigger drive later on the base station solution.
1. Will the connected USB drive function just like the internal drive in the Time Capsule for Time Machine use?
2. Will everything be transparent to Snow Leopard?
3. In case of both units with an attached USB drive - can I control who actually can see the drive and access it?
4. Do they support this DNLA thing so that e.g . PS3 can access an attached drive??

I've got an external drive that was a Time Machine backup drive. It's at the police station as evidence for something and they will not let me take it back. However, they will let me come down and make a copy of it. I might only have one shot at this so I'm trying to think of the best way to do it successfully and quickly.
Can I just bring another external with me, my Macbook, and then copy the files from the Time Machine backup external drive to the other external drive? If so, what is the facility for doing this quickly? I'm kind of new at Macs and am unsure. I do not have an extra Mac that I can simply use Time Machine to restore to to replace it's contents.

I would like to use FileVault to encrypt both my hard drive and time machine back up external drive. Does encryption noticeable slow down the computer.

Basically I have a 750GB hard drive in my Macbook Pro and over 300GB is taken up with 'BackUp' data. This is more than the total of everything I have on the drive other than that. Time Machine has always been setup on an external drive and when searching all files on the Macbook there is nothing for backup files so don't know where it is coming from.
Info:
MacBook Pro, OS X Mavericks (10.9.4)

I just replaced my HD on my 15"MBP. The install went well until restoring my data from Time Machine. The apps came over fine but none of my data did. Yes, I checked all the boxes on the "restore from backup" menu.
Of course now when I start up time machine the backup isn't there. How do I get Time Machine to recognize the backup? I have it on two places - a time capsule and a separate external HD.

Just wondering what experiences other people have had using time machine on a Mac Pro OS 10.5.2 with an external FW400/800 HD.
I am looking at a Lacie D2 Quadra 500GB to back up the standard 320GB internal drive. Never used time machine before, is it any good or is it better to use retrospect or similar. I never use more than 100GB of my main drive as most is backed up to DVD for extra safety. Is it worth getting a SATA card.

I have a MacPro, OS X 10.5.7. I have TM configured to back up to an external 1 TB firewire drive. I use Adobe Lightroom for photography. it provides a checkbox to allow you to backup all photos as you import them from your camera card. Adobe recommends selecting an external drive for these backups. But for some reason, it does not allow me to select the external drive that TM uses.

I have a 320GB internal drive and 1TB (MyBook) external drive. I recently bought a second 1TB external drive (MyVault)to use with Time Machine. I have removed the exclusion of MyBook so that Time Machine backs it up but so far it has refused to do so. It is happily backing up the internal drive. I have looked in the Mac OSX Leopard Missing Manual but still have no clue as to what I am missing. The initial setup (and backup) did not include MyBook until I discovered that I would have to remove it from the exclusions.

I'm looking to get a new drive to use with my MacBook for Time Machine. My current one (something from iomega) clicks like crazy whenever the backup runs, and drives me nuts.
I probably only need 250-320 GB, though I might get a larger one and partition it, using the other half for media, as I'm doing with the Iomega. My top priorities are a) quiet, b) off switch. Any recs?

So I've run into a Mac issue I'm not sure how to handle. I've got a Mac Pro running Leopard. I've got 3 internal Harddrives: 1.) 250 GB (runs my OS and applications), 2.) 500 GB (where I store all my source files for my business), 3.) 750 GB (serves as the backup for Time Machine for all the files on Harddrives 1 and 2.). So I began thinking the other day. What would happen if somehow all 3 harddrives were destroyed (theft, fire, power surge, flood damage, etc.)? I would lose years worth of source files from my business (graphic and web design files mostly).
So I went and bought a 1 TB external drive today. Ideally I would like to put the external drive in another location and bring it out maybe once a week to backup the 3rd harddrive from above (the one being used for Time Machine). Does anyone have any suggestions on how to backup this harddrive...some type of program that essentially acts like Time Machine? I just basically need it to mirror my Time Machine Harddrive. I found a program named Super Duper (http://www.macupdate.com/info.php/id/13803/superduper) not sure if anyone has had experience with it or not. I'm open to any suggestions on how to use the external harddrive to back up my Time Machine harddrive.

I have had Time Machine configured to back up my photos and videos on an external drive. My Time Machine backup is a separate drive attached to my MacBook by FireWire. I have Leopard OS. I have in the past successfully retrieved deleted photos from the Time Machine backups using iPhoto.
Now, unfortunately, the external drive with the photos and videos has developed a problem (possibly power-related) so that my MacBook no longer recognizes that drive. Obviously, this means that iPhoto can't find/open that photo library. Which means that iPhoto can't access the backup via Time Machine. The photos must surely be on the Time Machine backup but I can't figure out any way to retrieve them.

I recently bought a small capacity external hard drive. I don't download and store music, movies, et cetera so I purchased a 250gb Western Digital portable one.
I want to mostly back up my writing (I do a lot), some photos (for convenience, although I don't have many), and files (I have client information on my computer). So for the most part, they are small things.
If my computer was to crash, my worry is mostly that my writing would be lost. My question is, if I use Time Machine, does it automatically back up everything ? Or do I select things? Am I better off dragging and dropping? I am new to this.
Also, I also run Parallels as for one of my jobs, I have to use a Windows based program. I don't do anything else in my Parallels. If I was to lose the info on my computer, and Parallels was backed up, would I have to reinstall it on a new computer? This concerns me as I no longer have my Windows CD that I needed for the initial installation.

I was trying to move all of my movies on to my external hard drive and I copied all of them (took two hours) on there. Then I deleted all but three of them off my computer and emptied the trash. I then look back at my hard drive's files and they aren't there!!! The only thing that was there was the 3 files.
But I also have time machine saved to update my external hard drive. It did and I can see the previous computer times/events/whatever you want to call it. I go to Hard drive>backups.backupdb>My Mac Book Pro>2010-05-04>Macintosh HD>Users>Me>Movies which only shows my iMovie library. I do the same thing but with Music>iTunes>iTunes media>movies to which only one file shows up.

I have a Macbook Pro 13.3" running 10.6.4. I've had this computer for a year now and I have always wondered. Can my 500 GB Toshiba Hard Drive be used for Time Machine and for storing files at the same time?
I've heard about partitioning it, but will that delete the files on there? I dont have enough space on my hard drive to backup my external HD.
