Imac or time machine doesn't recognize ext. hd in lion

i had the connectivity issues once i upgraded to lion.  once i changed from wep to wpa2, connectivity issues disappeared but now my ev=xt hd isn't recognized by the computer or time machine.  i just downloaded the update (10.7.1) thinking that would take care of this issue but no dice.  is anyone else experiencing this issue?

nevermind! time machine suddenly recognized the disk after half an hour. sorry, I don't know how to delete this post!

  • Replaced internal hard drive, time machine doesn't recognize as same volume

    Howdy,
    The hard drive (call it drive "X") on my iMac (one of the 2005 models) was dying so I had it replaced. I rebuilt the new drive (drive "Y") from my most recent time machine backup (from external drive "A"). I am now having problems with one of my backup devices, in that time machine doesn't recognize that the new disk is conceptually the same thing that had been backed up before (same volume name).
    More details... I rotate my backups monthly through three external drives (I store the most recent offsite). After the disk replacement and restore process, I continued to use that backup drive (drive "A") without noticing any problem. Then it came time to rotate my external drives, and time machine doesn't find enough space on the next backup drive (drive "B"). Presumably this is because it doesn't realize that the drive I am backing up ("Y") is a copy of the drive that had previously been backed up on "B" ("X").
    Is there any way to convince it they are the same? Or am I in the same boat as this poster:
    http://discussions.apple.com/thread.jspa?threadID=2770362&tstart=0
    Basically I just want to verify that I am in that same boat before I remove old backup files on "B". If I do decide I need to remove those, are the instructions linked in thread 2770362 correct, or are there better ones?
    Thanks for any help,
    Bob H

    Actually, the backup I deleted above was the backup for the new internal drive. Apparently TM had created the (incomplete) backup during the failed attempt that ran out of space on the backup device. Since the new internal drive had the same name as the old internal drive, I didn't initially realize that's what I was deleting. Not that deleting it causes any harm, but it didn't address the original problem of freeing up space on the backup device.
    Not to worry though. I've figured out how to get at the backups for the old internal drive, and am in the process of deleting those. I was about to follow the instructions in your troubleshooting items E3 and E2, but upon attempting to enter time machine I stumbled into the right place. Since I had previously told TM to do no backups (because there was still not enough disk space), and since I'd left the backup device connected, when I pulled up the TM menu from the menu bar, the usual "Enter Time Machine" menu was replaced by "Browse Other Time Machine Disks" (or perhaps "Disks" was "Backups"). This then gave me a list of the machines that I'd backed up on this backup device (in my case machine names and internal drive names are the same). Of course one of those was for the old internal drive, and after choosing it I roughly followed the same course of action as I did a few days ago, to initiate deletion.
    I also saw how I could delete each of those old backups individually, but decided against that as I did not expect it would free up enough space. My expectation is that nearly all the space is shared among all the backups for the same source drive, since relatively very little changes between backups.

  • Time machine doesn't recognize external hard drive

    Recently I went to the apple store to get help to switch from Mavericks to Mountain Lion (I had some problems with Mavericks). They used time machine to bring back my applications (from my external hard drive, LaCie) on the Mountain Liion software. They said my time machine/external hard drive should work the same when I got home. Now, when I go to back up my computer, time machine doesn't recognize that I've backed up my files before. In the past, when time machine was working, every time I plugged in my hard drive the icon for it would turn blue, time machine recognized it, and it would back up my files. Now, the icon for the hard drive shows up, but time machine doesn't recognize it.
    Some other things:
    - when I open my external hard drive on finder, it shows all of my previous back ups
    - I used disk utility to check my hard drive and macintosh HD - both are OK
    How can I use time machine to continue backing up files? Or am I going to have to partition or erase the hard drive and start a new back up?
    Thank you in advance

  • HT203177 Time machine doesn't recognize my hard drive archive

    I have time machine archive on a hard drive (not time capsule). It recently stopped backing up. On checking, time machine recognizes the hard drive (in preferences it is listed as the back up drive.) The files appear to be present on looking into the drive, but Time Machine doesn't recognize that there are backup files there, it wants to complete another full backup. Meaning - it says for latest backup: "none".
    I am afraid if I do another full backup, I will lose the ability to access the older backups.
    When I try to access older files through time machine, it predictably cannot find them.
    How do I tell Time Machine that the files on that hard drive are the backup files?

    Update:
    1) Right click on TM icon - Menu choice "Browse other TM disks" allows me to see the data - i.e. it is a valid TM archive, not corrupted.
    2) Looking at TM preferences immediately after showed the proper disk was targeted, but still Latest backup: None.
    3) Shut down, anomalous shut down -required power button hit. (AHH - the problem??)
    4) restart using command  - R  works - i.e recognizes the disk and emergency recovery system software
    5) Restart - Still shows latest backup: None
    6) trying to access data through standard TM startup shows data now.
    7) go back to preferences - still no backup shown.
    Aside - I can't recall what the purple vs white dates on right side of the screen signify, and can't find it in the documentation right now. Anybody know?

  • Time machine doesn't recognize my old backups after clean install

    Time machine doesn't recognize my old backups after clean install of OSX Lion
    I also tried using migration assistant with no success.
    I just want to use TM to restore files and folders SELECTIVELY.
    Does anyone also know how to fully restore my iTunes data? (purchaces, music, iphone backups, etc)
    Thank you in advance

    Oh yeah, and the other thing is, now I CAN'T go back in time using my Time Machine back-up . . . It says I've never backed up now (I guess because this is a fresh install that's TECHNICALLY correct), but I restored from this Time Machine file . . . Surely I've done something wrong that can be fixed. Help, please?

  • Time Machine doesn't recognize old sparsebundle after new logic board

    Installed new logic board in pre-Isight 20" iMac due to capacitor swelling and kernel panic. I had also erased the internal HD. I was able to restore all my files to internal HD from Time Machine backup on the 1TB Time Capsule. Now I'm trying to back up my restored iMac to Time Capsule, but there is insufficient space. Time Capsule has three sparsebundle files: one for the 20"iMac prior to new logic board, one for a Powerbook, and one for a newer 24"iMac. Time Machine wants to create a new sparsebundle for the restored iMac, but there is not enough room and I would like it use the residing sparsebundle so that I will have backups prior to the point the new logic board was installed. I tried just changing the name of the old IMac Time Capsule sparsebundle file to the new sparsebundle filename that Time Machine creates when attempting backup, but that did not work. Any suggestions?

    1. I thought of just deleting the old sparsebundle in order to make room, but it was a less elegant solution because: a) I'd have to do a complete (i.e. lengthy) backup when really only a few things have changed (mostly software updates) since the restore. b)if something should go wrong with that process, then I've lost my backup file to restore the computer. True, I could archive the old sparsebundle to another drive, and then delete it from the time capsule, but somehow I think there should be a quicker, less labor intensive way that doesn't involve bringing in another hard drive.
    2. I believe you can restore any Mac with any time machine backup. If you boot from the system disk, go to utilities, and select restore from time machine backup, it then allows you to pick any of the files on the disk that time machine has backed up to. After all, even though Time Machine thinks this is a new computer, the restore that I just did makes it essentially the same computer that I had before the failure of the logic board--the desktop looks exactly the same. BTW, the Apple authorized service center that did the logic board replacement had put a clean version of 10.6 on the internal hard drive, and I was unable to use that system to do the restore--it just hung up. I had to do the restore using my system disk CD (and basically downgrading to system 10.5.8)

  • Time Machine Doesn't Recognize Drive

    My Macbook Pro died the other night -- it wouldn't wake from sleep and couldn't be restarted -- and it now has a new logic board. Everything seems okay, but Time Machine no longer recognizes my time machine backups. The files are all there, on the same drive they were always on. But TM doesn't see them and won't back up, giving me an error that the time machine drive can't be found.
    So I re-specified the drive in Time Machine preferences. And now TM now says that it doesn't have enough room for the backup on that drive -- presumably because it wants to start over and back up the whole drive again.
    I've checked both the internal drive and the TM drive with Disk Utility. No problems found.
    Does anybody have any ideas?
    Thanks very much,
    Steve

    Thanks for responding. Yes, I see. New logic board, new computer.
    If I have to start over, I'd like to hold on to those old backups -- and put the new backup on the partition where the old one was. So I tried copying the whole TM backup to another partition, where I could keep it for protection.
    But apparently you're not supposed to do this. The finder asks for your password twice in order to do it and it took about a half hour just to prepare to copy -- and it counted about 2 million files. Is there any way to back up the back up, or do I just blow it away?
    In that FAQ they refer you to an article that allows you to use the terminal to point the Mac back at the original backup. But it seems pretty fragile and easy to make a mistake. (http://www.macosxhints.com/article.php?story=20080128003716101)
    I also called Apple support and after escalating the call I got a guy who was willing to do much the same console thing. We started and immediately got an error from the console. If the Apple guy can screw this up, maybe I should stay away.
    Suggestions? Do I just give up and start over?
    Thanks again,
    Steve

  • Time Machine doesn't recognize old backup after logic board replacement

    I recently had my logic board on my MacBook Pro replaced and when I tried to backup, Time Machine did not recognize the old backup on the drive and tries to create a new one. The drive is mounted fine.
    Is there a way to continue using my old backup, or do I need to delete it and create a new one?

    Hi there I've just had this problem on my computer too but is there a possibly easier way to explain what is on this site...
    http://www.macosxhints.com/article.php?story=20080128003716101
    I read through but got lost about half way down when it says:
    "The last bit of information needed is the old MAC address. Open Terminal and change directory to the root of the Time Machine backup database, then get the old MAC address:...."
    I was in terminal but couldn't work it out. Is this not a good idea to stumble around in if i have no idea what I'm doing? Seems difficult but I really wanna work it out because my Time Machine hard drive is full so I can't just get to back up everything from scratch and don't wanna delete what is already on there. Any help would be much appreciated!!
    Hi, and welcome to the forums.
    If you're not comfortable with the procedure, I'd advise against it. Mucking about with Terminal can cause all manner of problems.
    But you can find your Mac's Ethernet Address via the *System Profiler* app. Click the Apple logo in your menubar, then +About This Mac,+ then +More Info+ to start it.
    Select Network in the sidebar, then Ethernet in the upper panel. Near the bottom of the lower panel, under Ethernet, you should see *Mac Address.* It's 6 hex numbers (12 characters), separated by colons. Omit the colons when you type it into Terminal.
    As noted in the Troubleshooting Tip, it's easy to do this wrong, get no error message, and have it not work (been there, done that!).
    If it doesn't work, your only choices are to erase the drive and start over, or get a larger one and transfer your backups to it (see item #18 in the Frequently Asked Questions *User Tip* at the top of this forum).
    How big is your TM drive, vs. how much it's backing up? TM usually needs 2-3 times the space of what it's backing-up (see item #1 of the FAQ Tip).
    Are you so concerned about not losing your backups because you've been deleting things from your internal HD, relying on TM to keep it's copies? If so, post back -- that's a terrible idea.

  • Time machine doesn't recognize old time machine backups after new drive

    After getting my original hard drive replaced on apple care. Time machine refuses to recognize time machine backups dating back to October when I first installed Leopard. The Records are there on an "off-board" Lacie drive. Any fixes for this? I have had so many problems with Time Machine I am afraid to turn it back on. Last time it took over 40 hours to do an initial back-up.

    Yes I had been having multiple problems and once saved the entire system in archive and install and also time machine had been active since October when I first installed it. all of this was saved to an off-board Lacie drive I can find the old time machine files easily enough but time machine since the new drive, does not recognize them. Since I got the drive back with tiger installed, I first had to re-install Leopard so I don't know if that caused Time machine to start over . I did do an archive and install at that time but there was nothing really to archive since they had not recovered my old files. If this wasn't bad enough The Technician replaced my administrator password with his own and the was off for a few days and I couldn't do anything for awhile. You have been very helpful thank you for your time on my behalf.

  • Time Machine doesn't recognize past backups anymore

    My Macbook pro just came back from being repaired (issue with the video display).
    I think they had to replace the logic board or graphics card or both - but I'm not sure.
    Everything works fine now... except for Time Machine.
    Before the Macbook Pro was shipped off I would backup regularly to an external hard drive.
    While my Macbook was gone I had to use some of the backup files from within the Backups.backupdb file system. So on my Powerbook G4 with Tiger I had to go in manually and copy files over. No big deal... or so I thought.
    Now Time Machine does not recognize the past backups from before I shipped the MacbookPro.
    It just wants to start an entirely new backup again.
    Is there a way I can get Time Machine to recognize my old backup again?
    I'd hate to have to go in manually from now on. It's not exactly convenient.
    Any help would be greatly appreciated.

    OK, I didn't explain that well...
    So here is what I'm typing in and what I'm getting back (the name of my computer being "Jason Argo's Computer":
    Last login: Thu Jul 17 22:22:16 on ttys000
    Macintosh:~ Jason$ cd /Volumes/Chubs/Backups.backupdb
    Macintosh:Backups.backupdb Jason$ xattr -p com.apple.backupd.BackupMachineAddress Jason Taylor's Computer
    I don't know why but I'm getting nothing back now. Before I was getting errors saying no such directory exists. I've typed in ls as well and get nothing.
    Any ideas?

  • IMac freezes & Time Machine doesn't work anymore

    Hello,
    For several days now my trusty iMac (two years old) keeps freezing without a recognizable pattern. Programs like iTunes, iPhoto or maybe even the Finder just stop working and display only the rotating ball - the only thing left to do for me after that is to manually terminate that process or (in the case of the Finder) to restart the whole iMac. I'm really clueless as to where this behaviour suddenly comes from, up until about a week ago the iMac worked perfectly. And now something like this happens every single time I start it.
    Another thing that doesn't work anymore is Time Machine. My last automatic backup is from September 17th. After that it just stopped working. Every time an automatic or manual backup is initiated it just says "Searching for backup volume" but doesn't find it, even after several hours of looking. The Time Capsule itself works perfectly, no errors whatsoever.
    My iMac is up-to-date, I also already ran the disgnostics of the hard drive program - everything seems to be fine. Can anyone help me?
    Thank you in advance,
    Paul

  • Time Machine doesn't recognize hard drive

    I have installed Leopard on my 2.66 GHz PowerMac. I have a 200 GB Maxtor hard drive hooked to it my PowerMacthrough a hub. I have used the hard drive to manually back up files and that works fine. The hard drive shows up in the finder, but it doesn't show up in Time Machine. I have tried restarting several times to no avail.

    I have a different issue but this topic seemed the closest in the discussions. Since buying our new 24" iMac with 750GB internal HDD this Winter (and Leopard) I have had Ext TimeMachine HDD issues (loss).
    First, I bought a 1Tb WD MyBook - within a week of use as the TimeMachine drive (and a week of good backups as far as I can tell as we browsed the saved contents periodically) the Ext HDD started failing. It was hard to tell what the problem was, but after twice "locking up" and restarting both the drive and the Mac, I am no longer able to "see" the drive in Finder, nor does the drive act like it would (the lights/sounds of the drive at time of mount) like it is being recognized at startup. One last odd thing about this drive, when TM had trouble and "sort of" locked up or slowed down the iMac as it lost the drive, Finder could still see it (I didn't try to move files to/from it though).
    Just last week I bought a Maxtor 750GB drive (to replace until I get the WD drive back from warranty) and it lasted only 3 days. Now it, like the WD drive, is not visible. The only difference is that this drive doesn't sound right e.g. if you listen closely I think you can heard the internal mechanism clicking - bearings, drive head etc.? I'm not a HDD expert but I suspect something physical.
    I am suspicous that both drives would fail in such a similar way with similar results. The only things common that I can identify now are the following;
    -Both drives are firewire (WD FW800 / Maxtor FW400)
    -Both drives used as TimeMachine drives only
    -Both drives were new
    -the location of the drives and iMac are not new - our older iMac and drives used to be mounted in the same location. The old Ext HDD's and iMac have been moved to a new location and they still work fine.
    - We have installed the latest Apple software updates as they became available and no other problems noted. However, it was during the last security update the the system locked up (from TimeMachine it appeared) and upon re-boot of the system we were no longer able to "see" that the drive was available.
    -Both drives have only been connected to this new iMac
    -No other Ext, HDD's have been used with this iMac
    Until I get warrant details back from the manufacturer I am concerned what the source of the problems are. Is it two unique HDD's failures and nothing more? Is it TimeMachine? Is it my iMac?
    I have invested a lot of time and money into large drives only to have them nothing more than paper weights in less then a week each.
    I would love to hear of any suggestions or if others are having similar issues.

  • Time Machine doesn't recognize my external hard drive

    My external hard drive is no longer recognized by my iMac. I have had this problem before and had to repartition the drive. There is not a drive that is available when I go into Time Machine preferences. Any ideas?

    If you completely repartitioned the external hard drive, you may need to Erase & Reformat each Partition on the drive now in order for them to be recognized.  You can do that in Disk Utility.

  • Slow iMac and Time machine won't recognize iMac hard drive

    I have an older iMac (2.16GHz Intel) that is upgraded to OSX10.6.7.  Recently it has been running very slow (although it did not seem to correlate with any particular install that I know of).  I have looked at the Activity Monitor and cannot find anything that is consuming vast amounts of memory (although I can't say that I really know what I'm looking for exactly, just no high numbers).  I did a Safe Boot and it is still really slow there (EXAMPLE of slow is taking several minutes to open a program or taking 27 hours to download my pictures (which only took 13 minutes on my MacBook)).  I know my iMac could use more memory (1G), but the slow problem is there even if only running one program.  I can't find a particular pattern to it, it just hangs up and then comes back most of the time.  It did however start shutting itself down recently.  I finally got into disk utility (I've been trying to run disk utility and it usually goes into an eternal spin that I can't even force quit - have to hard boot).   So from disk utility I ran verify disk in first aid - it says "the volume Macintosh HD appears to be ok."  I"m not sure what else I'm supposed to do in here either. So my first question is Does anyone have any other suggestions for the slowness? Second, in the meantime I'm desperately trying to back up my data on the time machine that I stupidly have never set up as a back up.  I can manually put files one at a time over there, but if I try to use it as a time capsule (system preferences, time capsule on) my hard drive does not show up as one of the options????  My external drive and the data that is already on the time capsule show up, but not my iMac hard drive. So my second question is How do I get my time machine to see my hard drive or is there another way to get my files to move over there? I realize I'm in trouble, any help would be greatly appreciated.  I've tried to provide as much info as possible.  Maybe there is something obvious I'm missing.

    My own response, or rather an update: I took the computer up to the Genius Bar - my hard drive is bad.  They are going to try to rescue my data.  For those of you reading this with a similar problem, make an appointment and go to the Apple Store if you can.  Mike, my personal "genius" for this encounter, said that stressing the machine when the hard drive is going bad just risks damaging it more.  If you potentially have a hardware issue, take it and let them determine what is wrong.  They have tools and diagnostics most of us wouldn't know how to use if we read about them here - and they have ways of retrieving data (I hope) that most of us do not have.  Please note that disk utility said my hard drive was ok, but the diagnostics they did showed that in fact my hard drive was much less than ok, but it was still "mounting" hence the disk utility reporting it was ok.  It is over an hour drive for me to get to the Apple store, and I only wish I had gone sooner.

  • Time Machine Doesn't Recognize Old Backups

    1) Had a mid-2010 27" iMac with Snow Leopard on it.
    2) Upgraded Snow Leopard to Lion. Lion recognized time machine disk like it should and backed up like it should. I was able to retain my backups I've had since 2008.
    3) This iMac had a hardware issue that prompted the purchase of a new iMac. Plugged time machine into this new iMac today and recovered system like I expected it to.
    4) Problem: I can't access my old backup sets. Time machine wants to start from scratch.
    Is there a work-around? Do I WANT a work around. In other words, if I can fix this so that Time machine "picks up" where I left off, will it cause problems later?

    I'll refer you to Pondini's site. See section B 5 & 6.
