Unable to keep my external hard drive connected to my computer for backup with Time Machine.

I am using an external LaCie hard drive to backup my computer. In the last month or so I have noticed that when my computer is in the sleep mode for sometime the hard drive disconnects from my computer. I than get an error message that tells me that I have failed to disconnect the hard drive device before turning it off. Do I have a problem and if so is there a fix for the problem.

Hi,
I have a similar question. I have backed up my external hard drive through my computer, onto my TC. When I go into TM, it doesn't show the external hard drive unless it is connected to the computer. Can I access the info from the external hard drive that is on the TC if I don't have the hard drive plugged in? If so, how can I do that?
Thanks,
Bernadette

What error message are you getting when you try to launch iTunes? (Precise text, please.)

The external drive must be connected to the Mac using either USB or FireWire
You must remove the external hard drive from the list of items that are "excluded" from backups in Time Machine Preferences.
Here's how:
Open System Preferences (gear icon on the dock)
Open Time Machine
Click Options
Look for the name of the hard drive in the list of "excluded" items and click on it to highlight it
Click the -- (minus) button at the bottom of the list to remove the hard drive from the list of "excluded" items....so it will now be backed up
Strongly recommend that you do the first backup using Ethenret from your computer to the Time Capsule since the entire contents of the external drive will be copied on the first pass. Ethernet will be 3-5 faster than wireless.
Once you have the first backup done, you can use wireless for subsequent backups since they will nornally be much smaller....unless you add large files to the external drive.

Once I upgraded to ML, I'm now finding that my Seagate Free Agent external hard drive is no longer being backed up by Time machine. Do I have to wait for Seagate to update their drivers for this hard drive?

I tried your suggestion, and it's been giving me the message "Preparing for Backup" for the past 8 hours. Does this mean TM is backing up my hard drive? I'll give it a few more hours, but if nothing else happens, I'm not sure what else to do. I'm not sure if there are any new external hard drives that are compatible with ML yet.

I am trying to confirm the time at which a particular backup occurred using an external hard drive that I have since misplaced. Although time machine lists the backup times for some backups, it does not list them for all. Can someone help?

Okay, I've sussed it. I saw a link to another discussion that hadn't turned up in any of my searches before I posted the question above.
My Tosh HDD was formatted to FAT 32 and therefore would not be backed up by Time Machine. I removed all data from it - nightmare as I hadn't enough space to put it on the macbook HDD, but, after trawling through numerous photos and deleting rubbish for hours, I finally made enough space and copied all data across. Then, after clearing the data from the Tosh HDD, I used disk utilitity to reformat it to Mackintosh OS Extended. Chose the option without kournalling because I'm not baking up onto this disk and so don't need it - according to some other discussions I found.
When it was done I check on time machine in system prefs and once I selected options, I was able to remove it from the excluded from backups list. Hey presto. Now I'm moving my photo library and my music library onto the Tosh HDD and my macbook should start to breath again. Hurray.

I recently had the genius bar change my imac hard drive because it crashed. For some reason Time Machine didn't back up some of my important files. Can I get my damaged hard drive back from the genius bar to see if I can access that info?

Unfortunately, that drive is long gone, probably back to the mfr. Drives are not returned when they are exchanged. You can go by and ask them, but the chances are slim to none.

I just fix my macbook air because it was kernel panic. They changed the hard drive. I could not back up with Time Machine, because it did not work and I had over Adobe creative suite 5 design premium student. But I finished my studies last year and I'd like to know how to get the serial number for me to reinstall Adobe creative suite 5 design premium when I am no longer study because I would still like the used? It is not fair if I do anymore because I really need.

You can download Creative Suite 5 here:

Failed External Hard Drive - Connect to another computer to repair??

Hi Guys
I have an older Maxtor External hard drive that looks like it has failed. At least that is what my Disk Utility says in my Power Mac G4. There is a solid red light, and just a blinking green, and it will not load onto my desk top on my Power Mac G4. But the weird thing is that I see it in my "System Profiler", and "Disk Utility", even +when it is not connected.+
If I connect this Maxtor hard drive to another computer, like my Mac Book Pro, to see if there is any life left in it, using disk utility or another recovery disk, will it do any harm to my Mac Book Pro? Is it contagious?
Thanks,
Anneita

No, it isn't contagious. Connect it to any computer you like.

Using an External Hard Drive vs. a separate computer for music producing

Hi all. I have a dilemma. I'm currently using logic express to make my music and its installed on my 13 inch macbook pro that I bought last year. Granted, it works fine, however I am looking to upgrade to Logic Studio soon as well as purchase Spectrasonic's Omisphere, which for those who don't know is about 50 gb of sounds. That on top of the 50 gb that come with Logic Studio means about 100 gb of software which I frankly don't have the room for on my macbook pro. I've been looking at buying a new mac mini, 2.3 ghz i5 with 8gb of RAM and a 500 gb Hard Drive, solely dedicated to making music. However, my friends tell me I should just buy an external hard drive and install Logic, as well as the software, on the hard drive since it will be far less expensive than buying a new computer. However, I don't know how I feel about installing software on an external hard drive. So my question is, given what I am trying to do, what is my best option? Are there issues with using an external hard drive for this sort of work that would make buying a seperate mac mini more practical, or vice versa?

If you want to do this in a cost-effective way, you should delete some files you don't need from your macbook pro to make room for logic pro. Even though Logic Pro has around 50 GB of stuff, most of it comes from the Jam Packs, which I'm guessing you won't really need to use...So make room for Logic Pro on your laptop and install it there...then use the external hard drive to store and record your music to.
If you're going to get a mac mini with that type of spec, you might as well buy a new macbook pro with the same specs and better.
Option #3, you can always upgrade your internal hard drive...there are plenty of sites on the net that shows tutorials and offers hard drives that have plenty of storage, faster speed, and you won't even need to purchase an external if you upgrade to at least a 1 TB, 7200 rpm hard drive.

What external hard drives are compatible w/ lion, snow leopard and time machine?

I am looking to buy an external hard drive to back up all data on my Macbook Pro that is currently running Snow Leopard, then upgrading to Lion. I want an external hard drive that is compatible with BOTH Snow Leopard (for use of creating a backup prior to my upgrade) and Lion (for daily use once I've upgraded). I also don't want to spend more than $100 if possible. Any suggestions? Thanks!

There is currently a shortage of drives due to flooding in one of the countries in which they are manufactured.
Getting one for under $100 at this point might be difficult. You didn't mention how full your current hard drive is, but for Time Machine, you should plan on two to three times the data you currently have (or expect to have).
I looked through Newegg's selection and didn't see more than a couple 1TB drives for less than $100. I recently bought a 3TB drive for $150. They're in the $200-$300 range, now.
I always buy bare drives and put them in an enclosure I buy separately. All the name-brand, ready-to-use drives come with a bunch of software you don't need and some of their software causes problems.
I had some bad luck/bad customer service with Seagate, so I've been buying Western Digital. Though, my replacement drives from Seagate have been going fine.
I've used Icy Dock and MacAlly enclosures. Both have worked well. If you do decide to go that route, you must make sure the enclosure can support the size of drive you buy (both physical--2.5" or 3.5", and storage size--1TB, 2TB, 3TB). The controllers in the cases may not be able to handle a 3TB drive, for example.
No matter how you go, you have to decide what kind of interface you want to use. USB is cheaper, but Firewire is faster. Firewire 800 is even faster, but costs more. All of that depends on what ports you have on the computer. OS X doesn't currently support USB 3.

External hard drive no longer found after becoming full from time machine, External hard drive no longer found after becoming full from time machine

Hi, I have been using an external hard drive as a backup for my Mac using Time Machine. I was under the impression that once the backup drive became full, it would start to delete previous versions of the backup. However, instead of doing that, it has just stopped working and I now cannot access the hard drive via a Mac or a PC. On the PC, it does at least show up in that it will allow me to disconnect it safely but I cannot do anything else with it.
I am now looking to reformat it, and start again from scratch - but can't do this as it doesn't show up anywhere. Does anyone have any advice about how I can get this working again?
Thanks.

Can you see the drive in Disk Utility? If so, try selecting it and using the Mount button in the top menu. You can also run repair disk and repair permissions.

External hard drive becomes "read only" and won't let Time Machine back up

I have an external hard drive for back up, and it has been working fine until recently.
There is a version of 10.6.6 loaded on it also.
The back up will fail every few days. When I do some checking, the back up drive is "read only" but I am not able to switch it to read/write. I cannot repair it with Disk Utility as the repair buttons are grayed out.
I can run DiskWarrior and it will fix it, but it runs super slow and takes all the memory to do it. I can barely use my e mail while it's running.
Anyone know what's going on?

System log says:
3/27/11 8:01:19 AM com.apple.backupd-auto[1559] Not starting scheduled Time Machine backup - time machine destination not resolvable.
It's read only because:
A: I cannot do repairs under Disk Utility, the buttons are grayed out.
B: I right click and "Get Info" and if I click on the lock icon, nothing happens.
C: The disk is not listed in the Time Machine backups.
I will try to take better notes the next time it happens and give you the exact messages.
There is another drive daisy chained to this external drive which holds my music. The music drive does not have a Mac OS installed on it and is only for storage. It works properly.

Can you use an external hard drive (G-Tech 1 TB) as both a time machine and for storing extra files?

I just got a new external hard drive and will be getting my macbook pro next week. I was wondering if the external hard drive could be used as both a time machine and to have extra files on it? And if so how would you do that?

Time Machine requires a drive that is formatted in Mac OS Extended (Journaled), so you will need to check to make sure that this requirement is met.
A drive that the manufacturer says will work with both Mac and Windows will not work with Time Machine.

I tried to install a new hard drive using Snow Leopard to back up with Time Machine. When I installed the new HD I installed Leopard (10.5) on it and tried to use time machine to restore the backup I had made using 10.6. Kernel panic screen occurred.

I backed up my system using 10.6 Snow Leopard's Time Machine to an external hard drive. I did this because I purchased a new internal hard drive to upgrade my 2007 White Macbook from 80GB to 320GB. When I installed the new hard drive, I installed 10.4 (Tiger) and then 10.5 (Leopard) and once Leopard was in I tried to use Time Machine to restore my backup from 10.6 (Snow Leopard) and received a kernal panic screen directly after the bootup.
The screen had code asking for 10.6, so does this mean that the computer is searching for Snow Leopard? If so, how can I do this? Will a bootable drive with Snow Leopard on it be able to solve the issue or will I somehow need to find a way to wipe out this new hard drive?

Booting From Snow Leopard Installer Disc
1. Insert Snow Leopard Installer Disc into the optical drive.
2. Restart the computer.
3. Immediately after the chime press and hold down the "C" key.
4. Release the key when the spinning gear below the dark gray Apple logo appears.
5. Wait for installer to finish loading.
Drive Preparation and Installation
1. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
7. After formatting is complete quit DU and return to the installer. Install Snow Leopard.
