Unable to access previous TM backups after re-selecting external drive

My MacBook Pro just came back from Apple repair, where it had its logic board replaced. (Hard drive is fine, and remained untouched.)
Upon getting it home and plugging in the external HD I've been using for Time Machine since November, TM would tell me that backup "failed" and that it "couldn't find the volume".
I tried turning TM off, deselecting the drive, then turning it back on and reselecting it. Now it tells me that there isn't enough room on the drive to perform a complete backup.
Problem is, that's not what I'm asking it to do! I just want it to recognize all my previous TM backups and continue doing its incremental work just as before.
I have a perfectly intact Backups.backupdb folder with three months' worth of valid TM incremental backups. Have I lost those forever? Am I going to be forced to erase this drive and start all over with TM?

RIGHT!!! I KNOW WHAT HAPPENED!!!! OK... Time Machine connects a computer to the respective folder, by the computers name and model computer. Since that is true, your computer's motherboard was replaced, which changes the addresses and id numbers, so Time Machine thinks it is a different computer. With that, Time Machine will not accept the fact that the computer has the same hard drive and will be stubborn to say that it will only be able to read the information from the finder and all it can do now is to start over. Unfortunately, Time Machine will stick to its guns to start a new backup.

Unable to complete Time Machine backup to Iomega 1TB external drive

I've read through all the posted topics related to Time Machine failing. I've run Disk Utility without errors; ensured that the external drive is formatted correctly GUID; 1 partition; Mac OS Extended (Journaled); downloaded TimeMachineBuddy; and still cannot get my new Iomega 1TB hard drive to complete a backup. My prior external drive, a LaCie, had no such difficulties but is now full.
Here is the TimeMachineBuddy error report. I am hoping one of you can help me understand what my next steps should be and thank you, in advance:

Thanks, Pondini.
I attached a new drive last night. Time Machine prompted me that it needed reformatting, which it did internally, without going to Disk Utility. It then started a backup but hung on "cleaning up" where I found it this morning.
Again, the finder was taken out with the TM hang and I had to hard reboot (on/off button - restart doesn't work nor does force quitting finder).
Here is the sad log from last night's attempt. Since it mentions an entirely new set of failures I am now ready to point to my computer as the faulty party. $180 worth of external drives into this, I am reticent about sinking anymore money into this until I rule out the computer itself. This line "NSFileHandleOperationException:* -[NSConcreteFileHandle writeData:]: Input/output error"
seems to be the essential problem.

HT201250 How can I revert to my internal drive for time machine backups after using an external drive?

Hi. I've been using an external drive for time machine back ups and decided to revert to my internal drive, but it isn't available in the time machine options. The only available option is to set up a time capsule, which I don't own.
Is it because not enough space is available on my internal drive (approx 50GB)?
Thanks!

50 Gb free on your internal drive is relly very low and of course not enought for a any kind of backup.
How big is your internal HD ? If you have left only 50 GB free it is probably 90% full. Let's imagine you have a 500 Gb. This means 450 Gb data and 50 Gb free. How can you backup 450 into 50 ?
Second point. The backup on your internal HD is a nonsense evenif it is big enough. If it stops working you will have no bakup.
Do you have an iMac or a portable ?
The portable automatic uses the internal HD if the external is not connected, but this is intended for a short time.

Unable to access time machine backups after creating new user profile

Hi,
I had visited the Genius Bar with some problems with iTunes not opening. The Genius had indicated that I likely had some corrupt files and that the easiest fix would be to create a new user profile... So we did...
After transferring all my data over to the new profile and setting everything back up as I like I deleted the old (presumably corrupt) user profile. To my dismay I no longer have access to any of my time machine backups that were created prior to setting up my new user profile... They appear to still all be there. However, I am unable to select any of the dates prior to the new user profile's creation and the deletion of the old profile...
Please help...
Thank in advance,
Des

That's correct. What you see in Time Machine's "Star Wars" display depends on what you have the Finder window set to. While looking at the new profile, you can't see any backups that were done before it existed.
You're right, they're still there, for now, but are grayed-out in the timeline at the right, because what's in the Finder window wasn't backed-up then.
If you select your internal HD or Computer Name in the sidebar, you'll be able to see those backups.
But since they're for a different user, you won't be able to view inside that home folder or restore from it -- one user, even an Admin user, doesn't normally have access to a different user's data.
It's doubtful, but you might be able to create a new user with exactly the same name as the one you deleted, log on to it, and see if the old backups appear.

Unable to access time machine backups after upgrade

I have an airport extreme with an USB disk that I've been using with my 10.8 system.
I've decided to format and do a clean install of mavericks. After that even tough I can access the timemachine and see scroll with the mouse I can't use the arrows or select anything.
Any ideas?

Unable to access previously downloaded songs after added new ones

i added some new songs to my nano and now they are the only ones that i can listen to. when i connect my nano to itunes i still cannot listen to any songs other than the ones i most recently added.

First, are the old songs showing on the Nano or are the new ones the only showing? Are you getting any types of error messages or icons when you attempt to play these songs in iTunes? You may want to try removing all of the songs from your ipod and re-syncing them back on to see if that helps. Also, try resetting the ipod.

Unable to access time machine backup. The folder "Documents" can't be opened because you don't have permission to see its contents.

My MacBook Pro with 750GB storage refuses to startup due to a problem with logic board (unfortunately I'm in Singapore and there is no Apple store here and zero customer support). I'm trying to access some of the files from the time machine back-up using my MacBook Air with 120GB storage, but I'm unable to open the backup. I receive an error message "you don't have permission to see its contents". Unable to access time machine backup. The folder “Documents” can’t be opened because you don’t have permission to see its contents.
I don't really want to migrate the data from the time machine to the MacBook Air as I simply don't have sufficient storage space on the MacBook Air. The iPhoto library which I'm trying to access is 200GB, which is more than the size of the MacBookAir.
Is there any way I can view the photos and documents stored on the time machine backup.
Thank you very much.

When you setup the Mac, you created a Admin user account with say name X
You ran Migration Assistant and it migrated user Y from the Windows machine.
User Y has different permissions than User X.
User X can't normally access User Y's account.
So what you do is log out of User X via the Apple menu and into User Y, this way you have permission to access the files.
If you want to transfer files from User Y to User X account
Transfer files between user accounts on the same machine instructions
Finder > Go menu > Computer
A window appears with your boot drive, double click on it to open
Inside is Users folder, double click to open it
Inside is your User accounts, double click on the one you want to send files too
Double click on the Public folder drop the files into the DropBox folder,
The permissions will change and can be used in the other user account when you log into it and moved to the appropriate folders.
Applications are typically installed and kept in the Applications folder which is a global access folder all users can access to run them from, but not all users can modify unless they are a Admin user.
Windows programs won't run on a Mac, but they can be instaled into a virtual machine program that is running Windows.
Windows in BootCamp or Virtual Machine?

HOw to backup photos on an external drive

I have an Imac and i store my photos on an external drive.
I just purchased a second external drive to use as a backup for the photo external drive. I plan to use Time Machine to backup the Imac.
How do I backup the photos on the external drive to the second external drive
thanks

Yes, dragging them over should do nicely. As for formatting, this is the procedure I use and an explanation as to why. It's slanted toward preparing a drive for Time Machine backups, but it doesn't hurt to do the same for any drive you will be using with the Mac OS. "Glasses", Kappy, and V.K. might have some other suggestions as well.
*_How Should a Time Machine Hard Disk be Prepared?_*
For Time Machine to work properly, the hard disk must be formatted “Mac OS Extended (Journaled)” and its’ Partition Scheme should be either GUID or Apple Partition Map.
Time Machine is incompatible with disks partitioned as Master Boot Record (MBR). Unfortunately, this describes nearly every hard drive you can buy because MBR is a Windows partition scheme. (Naturally, this DOES NOT apply to Apples’ Time Capsule.)
For some, Time Machine begins to perform as expected with a new external hard disk. But then the initial full backup or subsequent incremental backups fail. The user only later discovers the hard disk was still partitioned as Master Boot Record (MBR).
One article on Time Machine made this observation: “Virtually everybody will have to open Disk Utility and repartition the disk as APM or GUID. It doesn't really matter which one because the Time Machine disk will not be bootable anyway. APM allows a disk to boot a PowerPC, GUID allows the disk to boot an Intel processor but both are easily digestible by Time Machine on either kind of processor.” [http://www.girr.org/mac_stuff/backups.html]
It’s been recommended by many here that your reserve +at least+ double the size of your primary hard disk, that way Time Machine backups have room to grow as the size of your data grows. Additionally, the more space you give Time Machine the more history it can preserve. The less space you reserve for Time Machine the sooner older backups & deleted items will disappear.
One poster recommended this regarding multiple partitions: “If you do create multiple partitions (half and half would be a good place to start), make sure you use the first partition for Time Machine, and the second for your own stuff (the first one will be on top in the graphical representation shown in Disk Utility; you'll understand when you see the partition tab). This way, you can expand the Time Machine volume at any later time by deleting the second partition. Disk Utility allows this dynamic re-sizing of volumes, but volumes can only be expanded toward the end of the drive, when a volume that comes after is deleted to create the room.” [http://discussions.apple.com/thread.jspa?threadID=1712437&tstart=0]
Procedure
Connect the hard disk you wish to use for Time Machine backups.
Launch Disk Utility.
It will appear twice in the pane on the left. (Make sure you recognize that it is different from the 2 icons that represent your Macs' internal drive.) The upper entry represent the device as a whole, including the controller inside. The lower entry represents the hard disk contained within the device.
Click on the upper icon of the external hard disk.
Select the "Partition" tab.
For "Volume Scheme" choose "1 partition". (Choose 2 partitions if you intend on storing other data on the disk besides your Time Machine backups. Ensure that the two partitions have different names.)
Name the disk.
Format should be "Mac OS Extended (Journaled)".
Click "Options".
Select either GUID or Apple Partition Map. (See above for significance)
Click "OK".
Click "Apply". Then click “Partition”.
Once the external hard disk is repartitioned, select it again in Time Machine preferences and use it for your backups. If you chose to create 2 partitions, then select the first partition for Time Machine backups, and the second for additional files/folders.
Let us know if this was helpful.
Cheers!

Can i resume a Time Machine backup of an attached external drive (no system, just data) on a different laptop?

I am trying to find out if I can use a Time Machine (specifically on a 2013 Time Capsule) backup of an external drive (only data, no system) attached to a laptop, and then connect that same external drive to another laptop and resume the backup? Or is the Time Machine backup of an attached external drive a laptop "dependant" backup?
Additional info: The laptops in question are 15" MacBook Pro and a 17" MacBook Pro from 2011 running OSX 10.9 (Mavericks)

You are welcome.
I don't think there is a need to start a new discussion unless you want to.
You should have more than one backup of each computer. Hard drives do fail. Time Machine can alternate drives or have a Time Machine and a clone.
The concern arises because i was told that when a wireless Time Machine backup is interrupted the sparsebundle gets sort of "locked" or "damaged", and although the backups can be accessed, no further Time Machine backup is possible. One must that a brand new backup.
Apple support article. Don't let the title bother you. Look at Additional Information, which explains what happens when a backup gets interrupted. I also am including a link for troubleshooting. C3 explains what you can try if the backup is interrupted.

This means that your NAS does not support the required encryption. Update your NAS to the latest firmware or ditch it and buy a Time Capsule (they are the most reliable when using TM).

G'day. I am using iMovie 11 and need to clear disk space. How can I do that using an external drive, leaving me the option to go back and make changes or access old events or projects from that external drive?

G'day. I am using iMovie 11 and need to clear disk space. How can I do that using an external drive, leaving me the option to go back and make changes or access old events or projects from that external drive?

The slightly bigger question is whether you want to move all movie content to the external drive (essentially meaning that drive will always need to be attached when you're working with your videos), or whether you just want to archive older videos off to the external drive.
If you want to move all videos, then just move the 'Movies' folder in your home directory to the external drive, then create an alias of the external 'Movies' back in to your home directory. Now the 'Movies' icon in your home directory will point to the external drive and everything will just work (as long as the external drive is attached when you launch iMovie)
If you want to archive older movies then each Movie should have its own subdirectory within your Movies folder. These can easily be moved off to the external drive, and moved back should you ever need to work on those movies again.

Can the mac osxlion usb jump drive be used after as a external drive for storing media files

can the mac osxlion usb jump drive be used after as a external drive for storing media files

If you are talking about the Lion install USB thumb drive sold by Apple then no it can't. it has some specail formatting that makes it show up as a DVD drive and is securely locked from any changes.
But I must ask why would you want to. That would destroy that drive and wipe out the Lion installer.
USB thumb drive can be bought for $8.

I recently replaced my hard drive. When I reinstalled os I am unable to access my old backups. I can see them, but when I try to copy them over it won't let me.

Is there any way for me to access my old backups. I can see them but am unable to restore them, or copy them over.

How were the backup created?
