Time machine freezing after fresh re-install because of recovered corrupt files

Hi,
I have a Mid 2009 15" MBP running 10.8.2. Recently, my HDD crashed. And my time machine backup on an external HDD failed to mount (perhaps the backup was also corrupt?). I made an image using Disk Drill just in case and got a new HDD from Apple Support. They put in a new HDD and "recovered" my data. Now, the comp was behaving very very funny, freezing suddenly a few minutes after boot, requiring a hard shud-down and frequent kernel panics. So, I copied some of the important data in my Users folder and did a fresh install of ML on the new HDD. I also got a new external HDD and formatted it propoerly and copied back the files onto the fresh install of ML. At this point, I realised that there were certainly some files there that were corrupt(?) because, the copying back caused hanging a couple of times. Anyway, now the comp works just fine, but as soon as I begin a time machine backup, it completely freezes (just like before requiring a hard shut down), after less than a GB backing up. Please help me.

Hate to tell you this but the 2009 model MBPs were built, assembled, with a very cheaply made HDD to Logic board cable and your original drive may be fine and the cable is the thing that is failing.
I suspect this because once a drive fails it is near impossible to get any useful data off it. So if Apple was able to copy your files from the old drive to the new one that drive is probably still OK. And that you are now still having problems with the brand new drive.
No the problems you are having can not be caused by just having corrupted files store on the drive. The only files that are accessed by the operating system, while booting and running the computer, are those operating system files and whatever programs you are running. even if a program access those corrupted files it would not cause problems with the OS but may crash the program that is opening them.
As for TM not working that again is a sign that the cable is bad because TM can't copy the files to its backup over that bad cable.

  • Restore Time Machine backup on fresh Leopard install without disc.

    I just got my iMac back from the Apple Store where they fitted a new hard drive with a fresh installation of Leopard. I've got an external drive with a Time Machine backup of my old HD, but don't know how to restore it. Unfortunately I forgot to ask them about it at the store and now realise that I don't have the Leopard install DVD with me, only the Tiger ones that came with the iMac (which obviously don't have the time machine option).
    Is there any way to restore my data without the disc? It seems odd that they would install leopard after asking me if I had a time machine backup if I would just have to install it again.
    Any help would be greatly appreciated as I'd love to get my Mac back to normal without having to have my Leopard disc sent to me.

    You can use Migration Assistant, or re-create your user accounts from scratch and then selectively retrieve just what you need from your backups.

  • Can't access Time Machine backups after erase and install

    Had iMac checked by Apple Authorized Service Provider after experiencing multiple problems I couldn't fix. No hardware problem. He did an erase and install of 10.5.8. The machine accesses my Time Machine backup, but in Time Machine/ iMacHome/ Sharing & Permissions says, "You can only read." If I access a folder in Home, like Desktop or Documents, it says,"You have no access." Permissions are locked and grayed out.
    I spent over two hours on the phone with tech support last evening, and he finally said he'd have to turn it over to Apple engineers, which would take a few days.
    Migration assistant only allows "all or nothing" migration, and I need to select just certain folders; I do not want to restore anything that might be corrupted.
    Is it possible I could have an undetected hardware problem? Has anyone else done an erase and install and been able to use Time Machine backups to pick and choose what they wanted to restore?

    Thank you for your reply. The apple support tech should have known this, but he didn't. However, in the course of our two hour discussion he said "Maybe it's because the computer name is different." I hadn't reached the new-set-up stage where I had changed the name of the computer from Apple's default, so I did that. My short name home folder I had already named the same as before, iMacHome.
    But changing the computer name didn't help. After reading your reply, I unlocked the preferences (which were locked and grayed out in TM) to my home folder in the finder and assigned read and write to all folders within for everyone. Back in TM, preferences were no longer grayed out, but changing privileges was. I added iMacHome to the names in addition to staff read & write and everyone read and write. But ImacHome(Me) allows read only, options gray, and even though everyone is read and write, it says "You can only read" and I still cannot access Desktop, Documents, etc...
    Fortunately I have a SuperDuper user file backup that I am restoring from, so all is not lost. But it seems to me TM backups should be readily available, and I want to solve this problem. I may still want to go back to a previous month to recover something. But mostly I'd just like to know that TM is a functional backup. It certainly isn't in my case right now.
    Don't want to migrate the entire home folder. Too risky. Risky enough to bring over Mail and selected Application Support folders and keychains.
    Thanks again. I think your answer is right on, but there must still be something else. I know I have those names correct because I see the old computer name on the sparse bundle, and the old home name in the TM backups. (Haven't read the tips yet. Will do so.)

  • Cannot back up with Time Machine/Capsule after new drive installed in MacBook Pro

    MacBook Pro 2.53 GHz Intel Core 2 Duo running 10.8.5.
    I just had a larger hard drive installed by Tekserve. This is to be my first back up since installing the new drive. I have 2 back ups: one to my Time Capsule via WiFi, the other to an external Le Cie via USB.
    Time Machine just gives me preparing to backup but goes no further, just stuck in that mode. I suspect that it can't find my old drive, which it backed up till now. But I cannot find a way to correct this possible snafu. I do not see an option in Preferences.
    Any thoughts?
    Thanks

    Just so we are clear.. were your files all recovered from backup after the install of the disk?? Did you supply one of the backups to the company who did the installation so they could do the recovery?
    You do want to be careful not to damage the old backup.. it might really be better to start over a clean new backup.
    TM should be reset. It sounds like they did recover your settings.. Please check Pondini here.
    A4 http://pondini.org/TM/Troubleshooting.html
    Also use A1 to check what the log is saying about TM.. the old backup will need to be fully indexed and checked if you intend to keep using it.. and that will take several hours to the TC if you use wireless.. The problem people expect fast starts but that is not possible unless you are doing a new backup.
    You can also check some of the other help files there eg D1 long preparing for why that happens.

  • Time Machine freezes after clicking "back up now"

    Whenever I click "back up now" to start a Time Machine backup, the top of finder "rainbow wheels" and freezes for good.  The only way to get out of it is to restart the computer (relaunching finder does not fix it).
    OK, so why not let time machine just back up on its own?  It doesn't do that, either - when the time for the "next backup" arrives, time machine simply pushes the time back by one hour (if it was scheduled for 1:00 PM and the time arrives, Time Machine just re-schedules it for 2:00 PM).  It does this forever - it won't back up!
    The hard drive is a brand new 1 TB that is completely error free.  I am running OS X Mavericks 10.9.3. 
    Is this a known problem?  Any suggestions on getting around this? 
    Thanks!

    Wow, thanks for the help everyone! 
    Just in case anyone else has this issue, I solved it by re-installing Mavericks (not re-imaging/erasing) over my existing installation.  I'm guessing it was a bug with finder that was causing it.  Time Machine is now backing up without a problem.

  • Time machine freezes after restore using migration assistant

    after an erase/install done in an Apple Store, I restored my Mac Book from the Time Machine using the migration agent.
    To do this I created a temporary admin account and performed the Restore of all users and contents in the backup.
    Now logged in as my old user ID the time machine backup starts and identifies that the entire MacBook content needs to be backed up.
    TM Backup runs through the prepairing stage and reaches the "Baccking up 'xxx' MB from 'yyy' GB" message.
    Then it gets stuck after 120 MB has been backed up. I did run the backup for 2 entire nights in the 2nd night it got stuck after 0 kB had been backed up.
    What to I need to do to get TM running again?

    If you have more than one user account, these instructions must be carried out as an administrator.
    Launch the Console application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
    Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
    View ▹ Show Log List
    from the menu bar.
    Enter the word "Starting" (without the quotes) in the String Matching text field. You should now see log messages with the words "Starting * backup," where * represents any of the words "automatic," "manual," or "standard." Note the timestamp of the last such message. Clear the text field and scroll back in the log to that time. Select the messages timestamped from then until the end of the backup, or the end of the log if that's not clear. Copy them (command-C) to the Clipboard. Paste (command-V) into a reply to this message.
    If all you see are messages that contain the word "Starting," you didn't clear the search box.

  • Using Leopard Time Machine Backup after snow leopard install

    So I want to install Snow Leopard (and set up bootcamp), and I wanted to wipe my hard drive and do a clean install - because in the past i've had some trouble creating a bootcamp partition.
    would i be able to wipe and install snow leopard, and then easily restore my data and settings from a time machine backup?

  • Time Machine "resets" after Snow Leopard install.

    This may be answered in other threads, if so I'd appreciate a pointer to them. I couldn't find an appropriate one in my searches.
    I have a MBA and recently installed Snow plus the 10.6.1 update. I was having various issues and reinstalled Snow, leaving me at 10.6.0.
    I had deleted some applications to free up some space, and decided to restore them with Time Machine (TM). The first time I opened TM, it seemed normal and I restored one of the applications.
    Then my external drive where TM backs up to began to backup. Later I tried to open up TM and my desktop froze. After several reboots still had the same issue, I did a Safe Boot. Then rebooted as normal.
    Now TM asks if I want to start backing up, net new. It doesn't appear to see the old backups anymore.

    Try the Snow Leopard forums. You are now in the Leopard forums. Wrong place for a SL question.
    TM questions should be posed in the Time Machine topic area of the Leopard forums. At the top of the TM forum are three User Contributed Tips that you should read to see if you are able to find a solution for your problem.

  • Time Machine backups after a clean install

    I recently performed a reinstalled Snow Leopard on my Macbook Pro as it was suffering from running quite slow. Since I had upgraded this machine from an old Tiger install, I decided to manually migrate my files from a second backup, rather than restoring from my Time Machine backup on a Time Capsule.
    Now I'm up and running, I wanted to be able to view my old TM backup on my Capsule, and restore other files if I needed to, but don't seem to be able to.
    When browsing the Time Capsule, there is just the one sparsebundle for my backups, but when I enter Time Machine, it doesn't seem to read the older backups.
    I would like to either:
    1) Get TM to read my older backups
    or
    2) Clean them off
    I still have my second backup so I'm not worried about losing the old data, but I am hoping to be able to claim back some disk space on my Time Capsule, without having to create a whole new TM backup.
    Anyone got any ideas?

  • Restore iBooks files from time machine backup after clean install

    I just did a clean install of Yosemite. I still have a Time Machine backup of my Mavericks install. iBooks in my new Yosemite install does not have all of my books and pdfs in it - just the ones I can download from the iBookstore.
    Is there an easy way to access my Mavericks Time Machine backup to retrieve my old iBooks files?

    When I go back to the backup it does not let me go back to the previous backupprobably because the last backup was Lion and I am on Mt. Lion now.  don't what to do another backup if that is going to mess up the old one.  I can access it though by just going to it.  So i am putting that one on my desktop and I am going to rename it and see if I can open in Iphoto.

  • TS1545 I have downloaded 10.5.8 combo several times and cannot get it to install because the disc won't mount or the installation gets hung up after restart. My current os is 10.5.1, and I am trying to upgrade to snow leopard. This is on a dual core macbo

    I have downloaded 10.5.8 combo several times and cannot get it to install because the disc won't mount or the installation gets hung up after restart. My current os is 10.5.1, and I am trying to upgrade to snow leopard. This is on a dual core macbook pro.

    You don't need to update to Leopard 10.5.8 unless you want to keep Leopard. Upgrading to Snow Leopard requires that your purchase the retail install disk.
    The following covers Leopard:
    Some general advice on updating:
    It is worth noting that it is an extreme rarity for updates to cause upsets to your system, as they have all been extensively beta-tested, but they may well reveal pre-existing ones, particularly those of which you may have been unaware. If you are actually aware of any glitches, make sure they are fixed before proceeding further.
    So before you do anything else:
    If you can, make a full backup first to an external hard disk. Ideally you should always have a bootable clone of your system that enables you to revert to the previous pre-update state.
    Turn off sleep mode for both screen and hard disk.
    Disconnect all peripherals except your keyboard and mouse.
    1. Repair Permissions (in Disk Utility)
    2. Verify the state of your hard disk using Disk Utility. If any faults are reported, restart from your install disk (holding down the C key), go to Disk Utility, and repair your startup disk. Restart again to get back to your startup disk.
    At least you can now be reasonably certain that your system does not contain any obvious faults that might cause an update/upgrade to fail.
    3. Download the correct version of the COMBO update from the Apple download site.
    The Combo updater of Leopard 10.5.8 can be found here:
    http://support.apple.com/downloads/Mac_OS_X_10_5_8_Combo_Update
    If you prefer to download updates via Software Update in the Apple menu (which would ensure that the correct version for your Mac was being downloaded), it is not recommended to allow SU to install major (or even minor) updates automatically. Set Software Update to just download the updater without immediately installing it. There is always the possibility that the combined download and install (which can be a lengthy process) might be interrupted by a power outage or your cat walking across the keyboard, and an interrupted install will almost certainly cause havoc. Once it is downloaded, you can install at a time that suits you. You should make a backup copy of the updater on a CD in case you ever need a reinstall.
    Full details about the 10.5.8 update here: http://support.apple.com/kb/HT3606
    More information on using Software Updater here:
    http://support.apple.com/kb/TA24901?viewlocale=en_US
    Using the Combo updater ensures that all system files changed since the original 10.5.0 are included, and any that may have been missed out or subsequently damaged will be repaired. The Delta updater, although a temptingly smaller download, only takes you from the previous version to the new one, i.e. for example from 10.5.7 to 10.5.8. Software Update will generally download the Delta updater only. The preferable Combo updater needs to be downloaded from Apple's download site.
    Now proceed as follows:
    4. Close all applications and turn off energy saving and screensaver.
    5. Unplug all peripherals except your keyboard and mouse.
    6. Install the update/upgrade. Do not under any circumstances interrupt this procedure. Do not do anything else on your computer while it is installing. Be patient.
    7. When it ask for a restart to complete the installation, click restart. This can take longer than normal, there are probably thousands of files to overwrite and place in the correct location. Do nothing while this is going on.
    8. Once your Mac is awake, repair permissions again, and you should be good to go!
    If your Mac seems slightly sluggish or ‘different’, perform a second restart. It can’t hurt and is sometimes efficacious! In fact a second restart can be recommended.
    9. Open a few of your most used applications and check that all is OK. In this connection please remember that not all manufacturers of third party applications and plug-ins, add-ons, haxies etc, will have had time to do any necessary rewrites to their software to make them compliant with the latest version of your operating system. Give them a week or two while you regularly check their websites for updates.
    N.B. Do not attempt to install two different updates at the same time as each may have different routines and requirements. Follow the above recommendations for each update in turn.
    Lastly, Apple's own article on the subject of Software Update may also be useful reading:
    http://docs.info.apple.com/article.html?artnum=106695
    [b]If you are updating Safari (or just have):[/b]
    Input Managers from third parties can do as much harm as good. They use a security loophole to reach right into your applications' code and change that code as the application starts up.  If you have installed an OS update and Safari is crashing, the very [i]first[/i] thing to do is clear out your InputManagers folders (both in your own Library and in the top-level /Library), log out and log back in, and try again.
    So, disable all third party add-ons before updating Safari, as they may not have been updated yet for the new version. Add them back one by one. If something goes awry, remove it again and check on the software manufacturer's website for news of an update to match your version of Safari.
    Most errors reported here after an update are due to an unrepaired or undetected inherent fault in the system, and/or a third party add-on.
    Additional tips on software installation here:
    http://docs.info.apple.com/article.html?artnum=106692
    To reiterate, Input Managers reach right into an application and alter its code. This puts the behavior of the affected application outside the control and responsibility of its developers: a recipe for  problems. That's not to say that issues absolutely will ensue as a result of Input Managers, but you, as a user, must decide. If the functionality of a specific Input Manager or set thereof is really important to you, you may well choose to assume the associated risk.
    Again, the advice is to remove all Input Managers from the following directories:
    /Library/InputManagers
    ~/Library/InputManagers
    especially prior to system updates (they can always be added back one-by-one later).

  • Time Machine Bug after Restore

    Hi all,
    I've been learning Time Machine and will share two possible bugs if it is helpful.  I am working on a 2011 MacBook Pro, upgraded to Mountain Lion some months back, with 50 GB data on SSD being backed up to and restored from a LaCie SSD 80 GB partition so the speed is very nice: 14 minutes for initial backup and 7 minutes for a Reboot + Command + R restore.
    Bug #1.  Both (initial) backup and restores begin with large 60 minute estimated times in Time Machine Prefs Progress Bar but, once it gets going, finishes in 14 and 7 minutes respectively.  If symptom is due to some quadratic journal searching algorithm, it may explain why APL-CARE warned me about potential 16 hour restores and could be a bug.  If it is due to Time Machine just counting what has been transferred so far, then maybe not a bug (but maybe a possible enhancement request).
    Bug #2.  It appears that the first time Time Machine runs after a Cmd+R restore, it tries to rebuild an entire journal or record of what it has and, if you interrupt this initial backup, you break Time Machine.  The next time you try to backup, Time Machine thinks Everything needs to be backed up (even though your disk is identical to what it just restored), and it Fails in my case with message "Time Machine couldn't complete the back to [my LaCie drive because my 50 GB of data is already there and it thinks it needs a full 50 GB more]" in so many words.  APL-CARE (and its expert advisor) tried to call this a feature and sent me to your article HT3275 but that seems like a different issue.  Since I did not believe Time Machine was so stupid, I ran the sequence again and carefully avoided interrupting Time Machine during its initial backup following my Cmd+R restore and, indeed, it took about 8 minutes to backup 4.5 MB (and rebuild whatever it does that first time).  So this feels like a straight-up bug, Time Machine should scare me with a popup if I interrupt it while it is rebuilding its critical list for the first time after a restore.  If APL-CARE were correct, it would mean everyone loses all history after a restore, everyone needs to Erase their backup disk and start from scratch, and methinks that too would be a bug.
    Hopefully this is helpful, Time Machine is otherwise very cool and I love the Star Trek GUI. 
    Regards,
    Dave.

    And this is an ERROR in time machine.  I just did a test restore again, went quickly, then Time Machine is GONE, GONE, gone trying to restore 5MB, waiting over an hour when a fresh backup takes about 15 minutes.
    So only solution is DESTROY all my backups, then start over.  Really dumb, and this page has no option to change my post back to a question, also really dumb.
    I am going to swear now:  cr*p.  OK.  Fix your **** software please.  I'll deal with workarounds till then.

  • Time Machine "freezes" and I am NOT running anti-virus software

    I am incredibly frustrasted and disappointed as a first-time Apple user (brand new iMac (Intel-based) with an external LaCie 500 GB external hard disk). The problem is Time Machine. It backs up on schedule, but when I enter Time Machine, I cannot navigate at all. The background screen (outer space) moves, the cursor moves, but I cannot click on anything. I have to "force quit". So I guess I have things backed up, but can't do anything with them.
    I am NOT running antivirus software. I had Intego loaded on the computer, but removed it completely after reading on Apple blogs that this could interfere with Time Machine. I have reformatted the external hard disk. Still, Time Machine freezes. Apple has put out a couple of patches, I understand, but that was months ago and all of my software is up to date.
    I have called Apple support TWICE and they act as if I am from the moon -- how dare I question that the Time Machine does not work properly?
    Does anyone out there know how to fix this? I am ready to return this computer to the Apple store, which cheerfully sold me on the idea of an external hard disk as a back-up.

    Hello Zurichmike (lovely country):
    Welcome to Apple discussions.
    There are several things you could try. Easy ones first:
    Erase and reformat your external HD.
    Run repair disk from your software install DVD (on your internal HD).
    Go to Macintosh HD>library>preferences. Trash the TM preference file (com.apple.timemachine.plist) and restart. The TM preferences will need to be changed as they are now default values.

  • Time Machine Freezes and Corrupts Disk

    Hello,
    I have been attempting to set up one of my external hard drives for use in Time Machine, but every time I click "Erase" when Time Machine asks me to, Time Machine freezes, and my Hard Drive gets corrupt. After force quitting Time Machine and mounting my drive again, it says "The disk you inserted was not readable by this computer." I have had to go back to a PC on numerous occasions and format the disk as FAT32, and then come back and try it again. I have attempted to erase the disk through Disk Utility, but the same error occurs.
    I am attempting to do this with a 100GB Store-It drive by Hitatchi. Please let me know if anyone has any suggestions as to how I can solve this issue.
    Thanks,
    Thomas

    I had the same problem with a new 120GB WD external 2.5" HDD. It seems to perform the initial backup then gets frozen at the very end of the first actualization, CPU running at 100%. Doesn't mount any more, DU shows it but declares it as non-repairable because of different issues: index faulty, B-tree header faulty etc. The same on another Mac. Re-formatting leads to the same results.
    What to do?

    i am using for first time the time machine and an external hard drive because I want to erase my macbook and start from zero files. Am i keeping my files in the portable hard disk when I will connect it again with the macbook or the time machine will erase all?
    I would like to know if after I erase all my data, empy hard drive inside the macbook, the time machine will erase all my files that I have saved in my "WD "My passport" external hard drive

    Welcome to Apple Support Communities
    Time Machine has to erase the external disk in order to make backups. Before setting Time Machine up, copy the files of your external disk to the hard disk of the Mac in order not to lose them, and then, set up Time Machine. The first backup will start automatically.
