Reformatting Hard Drive after Time Machine

How do I reformat my OneTouch mini 4 hard drive after I've decided to stop using Time Machine with it? The problem I run into is I need to be able to go in between my MacBook and my PC. I saw FAT has a limit of 32GB, this won't work for me.
Did I do irreparable damage by using it with Time Machine?
Thanks.

Actually FAT32 can support more than 32GB - this is just a limitation set by Microsoft on its own format utility to move people to NTFS. There are lots of third party programs for Windows that will format a large drive for FAT32. I use Partition Magic. On the Mac side, I'm not sure - I've formatted flash drives for FAT but since I almost never have the need to share an external drive between Windows and the Mac, I just don't recall if I've tried formatting a drive larger than 32GB and I don't know if Disk Utility can do it. A quick search didn't turn up a definitive answer but it looks like it can.
But you can give it a try. Open up Disk Utility, select the drive and then select Partition. You'll see partition scheme - click on 'Current' and select 1 Partition. Then below the box you'll see an Options button. Click on it and select Master Boot Record and click on Okay. Now to the right near the top you'll see Volume information. Give the drive a name and in the popup menu, select MS-DOS. If Disk Utility won't format a partition in DOS larger than 32GB you'll get an error message.

How to reformat an external hard drive after time machine?

I have an external hard drive upon which I put movie files that I view through a Sony box (like the Roku box). I brought my MacBook in for a repair and connected the same external HD and used Time Machine to make a back up. It did reformat it in order to do so, but since the Sony box isn't a pc or mac I didn't think it would make a difference, but now the Sony box won't recognize HD. Is there a way to reformat it on my MacBook so that I can use it on the Sony box again, or do I need to reformat it with a Windows computer? I had no issues when transferring files only and using the Sony box.
If you give any instructions, please write them out specifically, don't just post "you have to partition it" and leave it at that. I am computer challenged when it comes to these things. Think instructions for a person one step above being vaguely aquainted with a Mac please. Thanks.

HT201250 Data recovery from WD Elements Hard drive after Time Machine formatted it

I plugged my brother in laws WD Elements hard drive into my MacBook Pro. It asked me if I wished to use this drive as my time machine back up to which I answered no. I was going to copy and paste some movies onto his drive. I not sure how it occurred but Time Machine has now "partitioned or formatted " the drive and erased all data that was on it. The drive appears empty on my MacBook and is now unrecognisable on his PC computer. The drive had some important documents and I am praying that I somehow can recover them. Does anyone have Amy suggestions as to where to start ?? Please help !!!

It probably got reformated to a Mac specification which is why the PC can't recognise it. I am not sure if any of the mac recovery programs would work but maybe someone else can advise you. One of the professional recovery businesses could help but are very expensive.

None of my purchased applications on hard drive after time machine restore

Hi,
My hard disk wiped out. I restored from my last backup using time machine, but now, all the applications I added to the basic package (eg handbrake, sibelius, MS office etc) have disappeared. I search and can't find them anywhere. When I look back at my previous time machine backups, I can't see an applications folder at all.
Anyone got any ideas?- Have I messed this one up? Many thanks in advance.

Did you exclude the Applications folder from backup in Time Machine's preferences? If so, it was never backed up.

Time Machine will not let me restore from backups after June, 2013. I can see the files on the external hard drive but Time Machine skips all of them and goes back to June, 2013. Does anyone have any idea what the problem is?

telling me to buy a new router is NOT a solution.
And why not? Apple is selling these things like BigMacs. They can't make enough of them. You've been suffering since May because you refuse to get a decent router.
Can you imagine if a company that makes a refrigerator told me that I needed to upgrade my electrical system to rectify a problem with their device? What kind of response IS that?!?!
What if the problem with their device is that it requires a new-fangled "grounded" outlet and your circa 1890 house doesn't have grounded outlets. Would you refuse to purchase a $ 25 adapter on principle?

Hi everyone, after updating to 10.6.8, i've been unable to backup to my external hard-drive on Time Machine. anyone having same issues?

I did a software update to 10.6.8. and I've been unable to back up my files to my external hard-drive on Time Machine. The error message it gives says "he backup was not performed because an error occurred while copying files to the backup disk."
It recommends using Disk Utility to repair the backup disk and i've tried that but it finds nothing wrong with the disk!
I even tried copying files off it so i could re-format the drive but it apparently can't do that and the error message is that there's a wrong case sensitive file. Please help, I really need a solution.
Thanks,
Regards,
Chi.

Restoring an external hard drive with time machine

I'm having a problem restoring an external hard drive using time machine. I'm on a macbook Air Running 10.7.5.
The external hard drive where I store all my photos crashed a few days ago. Not a total disaster, because it's backed up, but I can't figure out how to restore the drive onto a new hard drive. When I go into time machine without the corrupted drive attached, it does not show up in the time machine browser as an option for restore. (The files are definitely there, though, because I can see them when I look at the time machine files in Finder. I'm afraid if I just transfer the files by dragging, though, I'll mess something up.) I tried using the migration assistant, but I'm having the same problem there.
Anyone know how to do this? I'm a little frantic to get my photos back.
Thanks!

I am having a similar problem. I use a Lacie external hard drive connected to an Airport Time Capsule via USB to store my itunes library. Yesterday I disconnected the external drive from the ATC and connected it to my macbook pro via fire wire to transfer 40 gigabytes of media files from my laptop to the external drive directly rather than over wifi. When I reattached the external drive to the ATC the Lacie drive didn't show up even after rebooting everything. I then disconnected from the ATC and reconnected to the laptop and now I get an error message saying the Lacie disk is unrecognizable and needs to be reformated. The Lacie drive was being included in the time machine backups so the files should be available through time machine but I don't see anyway to access them because the Lacie disk icon doesn't appear in the time machine backups. Is there another way to browse the files?
I have had issues with Lacie disks not showing up on the desktop before, particularly when transferring files from one computer to another. The transfer usually goes fine but then when I reattach the drive to the first computer it isn't recognized anymore until I reboot and it sometimes requires a couple of reboots. I initially tried to connect the external drive to both the ATC and the laptop but that didn't work, although now I'm wondering if that was because the connection to the laptop was firewire rather than USB like the ATC. In any case I currently have over a terabyte of data on my lacie that I can't access which includes my entire itunes library and backup files from multiple computers which were "cleaned" but not restored.
Disk utility sees the drive but can't verify or repair and tells me to backup as many files as possible and then reformat. Unfortunately I can't see ANY files to backup because the disk won't mount anywhere. If anyone has a recommendation for utilities to recover the files I'd be most grateful to get them.

How to backup external hard drive to another external hard drive using time machine ?

Hello,
i have an external hard drive which i store all my drum samples and sound library on and files are contantly changing, adding new sounds, deleting old ones etc ..
So my method of back up as of now is to just copy all the edited files and click and drag to the back up disk.
Now, my question is, how do i back up my external hard drive to another external hard drive using time machine ? I read somewhere that you can do this, i cant find the post however. It would be nice to automate the back up process rather than manually finding the files to copy over.
Thanks in advance !

The question you pose is conditional, in that you should have more than an exact
capacity replacement for a clone, if the drive you are going from (or one going to)
has insufficient free space and that has a bootable clone on the drive; any space
tied up in a partition for Time Machine backup, takes away from the running space
if you should need to run the computer from a clone on the external HDD's other
partition.... Better to have a good capacity of additional reserve unused free space.
Be sure any clone copy that you hope to use as a re-close, that each in turn is tested
after a clone operation. Also consider using each running system's Disk utility and
have First Aid 'repair disk permissions'. Preparation of a new drive or even an old
drive that may have questionable artifacts or errors on it, should be reformatted. To
even go as far as Secure Erase (overwrite) at least one-pass before reformatting it
again, could help.
However, I'm not sure if the drives and situation you are looking at would necessarily
be a good match. It could work, but you'd need a reasonable size partition or hard
disk drive for a system. Snow Leopard and all its associated applications, can do
OK in a 100GB HDD. (My computers have more storage capacity than is used; so
for mine to have 60% free space, is good.) Virtual Memory is drive space used by
OS X, that can be a substantial amount for swap and temp files. Some applications
make duplicates of works-in-progress, for each change in an open file; that adds up.
{This question (& my reply) should've been in their own thread & not at the end
of one that is nearly three months old, + marked 'solved' by the original poster.}
So I guess I don't have a direct answer to your question; having just returned from
a few hundred miles and automobile issues, too. I'm not really thinking on-topic...
The clone should be on its own separate drive, and up to 3TB drive dedicated to
Time Machine may be overkill, however that software will consume old backups first
when it uses up all the space. Or usually that is what happens in TM backups. If
that isn't happening, there may an issue in how Time Machine is set up.
Good luck & happy computing!

Hard Drive for Time Machine for iMac with AirPort Extreme??

I just switched back to Mac after too many years with a PC. I bought an iMac 24" 2.8GHz with 4GB 667MHz DDR2 SDRAM and 750GB Serial ATA Drive.
I'm planning on adding an external hard drive for Time Machine to attach to my AirPort Extreme. From reading information posted on the Apple site and my AEBS I understand that it needs to be connected to the USB port on the AirPort Extreme.
While I may be opening up a technological "can of worms," I'd like to know what will be the most dependable drive 1TB, USB 2.0 that I can buy. Noise and bright lights are not a consideration here. I just want a drive that I can depend on to work with Time Machine. The "original" data will be stored elsewhere. I've heard of, read about and experienced so many hard drive failures that I'm getting "gun shy" about this subject. Please feel free to let me know what's good and bad. Thanks.

Here is a quote right from Apple's site today:
Quote:
AirPort Extreme lets you turn your external USB hard drive into a drive you can share with all the >users on your network. It’s called AirPort Disk, and it’s a simple and convenient way to share files >among everyone in your family, office, or class.
I tried to return my AEBS to Apple but I was a few days beyond their 14 day limit on returns (limit is bases on shipping date of the item in question, not when all parts of the shipment are received). Part of my reasoning with the Apple Store CS was the posts like yours saying that this couldn't be done. The Apple Store rep. and the tech. rep. that he claims that he spoke to said it could be done. The only way I could return the AEBS, according to the Apple Store CS rep., and get a new Time Capsule would be if I bought a hard drive and discovered that my AEBS would not work with the hard drive. No, I'm not a happy new customer. So, I want to buy a good, reliable hard drive and want to know which one to get.

I went to Mac Store and had replaced hard drive because I encountered 4HDD ERROR(hard drive failure). I had backed up my old hard drive by TIME MACHINE regularly. Now how can I restore everything I had?

Thanks for your response.
I had tried COMMAND+ALT+R which led me to directly to INTERNET RECOVERY via wifi. After 1 hour or so it dropped me at the same point.
I've tried MIGRANT ASSISTANCE as well, it kept on LOOKING FOR OTHER COMPUTERS even though I clicked on TIME MACHINE BACK UP USING EXTERNAL HARD DRIVE
so what to do now?
P.S. Guys at MacStore were so careless to even listen to me when I asked them about retrieving back up :(
Please help

External Hard Drive and Time Machine questions

Hello, I am new here to the forums and I have looked all over for the answers to two questions that I have regarding external hard drives and the time machine feature.
For some background, I recently had a scare (water spill but luckily I had a keyboard cover on and the entire spill landed on the cover) with my Mid-2012 13" Macbook Pro (2.5Ghz) and due to almost losing all my data I've decided to invest in an external hard drive. However, rather than just purchasing a 500GB HDD to use as an external hard drive, I decided to kill two birds with one stone and upgrade my Macbook Pro as well by investing in the 480GB OCW Mercury Extreme Pro SSD. I'll be using the SSD as my internal drive so the original hard drive that came with my Macbook will serve as my backup external drive. Lastly, I plan to use the external drive solely for the purpose of backing up my MacBook in case something ever happens to my Macbook.
I am using this guide to help me with this whole process: http://circuitremix.com/?q=content/macbook-pro-solid-state-drive-upgrade-guide-a nd-performance-testing.
My two questions are:
1) When following the guide, it never mentions anything about the Partition Map Scheme. After being alerted to this and doing some additional research, is it better to go with the GUID Partition Table rather than the Master Boot Record?
2) After I have cloned everything onto my new SSD and replaced the HDD in my MacBook with it, should I erase everything on my HDD before setting it up with time machine? I was thinking about keeping the original data on the original hard drive (which would now be my external drive) just in case something goes wrong with time machine but I have read that people recommend solely dedicating the entire external hard drive for time machine backups.
Thanks in advance!

Format the new SSD in Disk Utility to Mac OS Extended (Journaled) and that will solve question No. 1.
After formatting, clone the new SSD using Disk Utility>Restore or Carbon Copy Cloner (down load from the Internet). Test the new SSD and if it performs as expected, do the physical swap.
Question No. 2. Erase the Time Machine HDD using Disk Utility and then install Time Machine. See this excellent website regarding Time Machine.
http://pondini.org/OSX/Home.html
If you want an external boot HHD, get another one and use Carbon Copy Cloner. This will give you redundancy in backups as well which is a good strategy. CCC also can update the contents in an incremental manner similar to Time Machine.
Ciao.

How do I restore a failed external hard drive using Time Machine?

I have an external hard drive connected to my iMac that is being backed up with Time Machine. I just realized that should it one day fail and no longer appear as a connected device, I'm not sure how to restore its data to another external drive. When I disconnected the external hard drive (to mimic a drive crash) and entered Time Machine to see if I could verify that the external hard drive was, in fact, being backed up - I didn't know where to find it. Under the Today (Now) information, I didn't expect to see it there as it was no longer connected to the machine. But when I went back a few days, I expected to see its backup appear in the Sidebar. But no!
So - how do I restore a failed external hard drive using Time Machine?
Searches for this information on Google yielded "iffy" results. I'm hoping someone here is able to offer some clear steps to follow. Perhaps I'm missing something silly. Thank you very much!

I came across this discussion after encountering the same problem. Since my internal HD was cose to full I added an additional external HD to my setup. I moved my iPhoto files to an external HD and backed both this external HD and my internal HD up with Time Machine to another external HD. So far the theory. When I wanted to test if this setup worked I noticed that I could only see my iPhoto libraries on the external HD in Time Machine when the external HD was connected to my computer, but not if I turned it off. This led me to search for a solution on the Apple Support Communities discussion board.
The suggestions made Kappy seem right, at least in my experience, in that my Time Machine simply did not back up the external HD until I followed the steps he suggested above. These were the following:
"So, if you want it backed up then here's what you need to do:
1. In Time Machine preferences remove the external drive from the Exclude list.
2. Verify that it is now included with your other drive in the backup list.
3. Do a Backup Now to create a new backup of the external drive."
After doing this, my external HD showed up in the Backups.backupd as a seperate folder. I could clearly see the Time Machine back-up for my internal HD and my external HD. In addition, in Time Machine itself I was able to find the external harddrive by clicking on my own computers name under "Devices". I hope my experience helps to resolve your issue as this discussion board has helped me resolve mine (which I believe to be very similar).
Cheers!

IMac won't boot if external hard drive running Time Machine powered on

Upon rebooting, my iMac 3.06 GHz Intel Core 2 Duo with 4GB RAM, running OS X 10.5.4, locked up in a gray screen, the "gray screen of death."
At the recommendation of the Apple Tech Support rep, I turned off the iMac using the power button, and rebooted with my USB and Firewire devices removed.
The iMac boots fine with everything except my G-tech drive 1GB external hard drive running Time Machine with no partitions, attached using a Firewire 800 cable.
If the external hard drive is on, I get the interminable gray screen.
If I boot with the external hard drive powered off and then power it on after I'm at the Mac desktop, the disc image mounts normally on the desktop.
I've already repaired all disc permissions and it doesn't help.
My external hard drive has used 907 of the 931 GB true capacity. Supposedly, Time Machine removes the old files to make room for the new files.
Time Machine itself is running properly once I get my iMac booted in this peculiar way.

Raja,
Do a SMC reset perhaps even a couple of times and see if that helps. Also in System Preferences + Startup Disk make sure the internal HD is selected.
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.

HT1553 I restored my hard drive from time machine. Why is iPhoto not displaying images properly?

I restored my hard drive from time machine after power blinks corrupted the file system so badly that disk utility could not repair it. Since then, iPhoto has not displayed images correctly. Events are there, and blank squares are shown, but that's all. I rebuilt small and all thumbnails and permissions -- I think the top three or four options in the iPhoto rebuild utility, which took five hours to do but which seems not to have changed anything. The iPhoto library is still more than 100GB, so the photos are there. I didn't choose rebuild from backed up --- whatever the final option on the rebuild menu offers -- because that seems to be appropriate only when a backup is interrupted. Could certainly do it, though. How do I get iphoto behaving again? I have full time machine backups saved automatically and another fairly recent copy on a separate hard drive stored remotely. Thanks for whatever help anyone can provide. I've looked at existing questions and solutions without success so far.

What version of iPhoto and system are your running? Since you've tried rebuilding with iPhoto give this a try:
Using iPhoto Library Manager to Rebuild Your iPhoto Library
Download iPhoto Library Manager and launch.
Click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option
In the next window name the new library and select the location you want it to be placed.
Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments. However, books, calendars, cards and slideshows will be lost. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.
If you have an external HD you might want to have the rebuilt copy created on it unless you have well more than 100 GB available on your boot drive.
