  • Time Machine Backup error - The backup disk image "/Volumes/Data/Extreme.sparsebundle" could not be accessed (error -1).

    I am getting a Time Machine backup error "The backup disk image “/Volumes/Data/Extreme.sparsebundle” could not be accessed (error -1)."
    Then a Finder window pops up with the backup directory in it.  When I open it I see all the backups that were completed successfully and then the one there is simply always shows the data and .inProgress.  I thought that maybe if I could delete the one that is perpetually in progress it would start a new one and run fine, but I won't let me delete it.

    Reboot the TC.. or go to the 5.6 utility.. and disconnect all users.. to force it to reconnect.

    I've cleared almost 30 gig off of my hard drive in the past 2 weeks, and it will temporarily show that in the Get Info box.  But hours later, I am still getting a disk full error and all of the memory has disappeared.  I have cleared my backup logs from Time Machine, checked the mail folder, cleaned out tons of photos and videos and it still keeps filling back up.

    Any ideas on what to do next?
    I'm running and iMac 20-inch  early 2009
    Processor  2.66 GHz Intel Core 2 Duo
    Memory  8 GB 1067 MHz DDR3
    Graphics  NVIDIA GeForce 9400 256 MB
    Software  OS X 10.8.4 (12E55)

    Step 1
    Quit Calendar. Triple-click the line below to select it:
    ~/Library/Calendars/Calendar Cache
    Right-click or control-click the highlighted line and select
    Services ▹ Reveal
    from the contextual menu. A Finder window should open with a file named "Calendar Cache" selected.
    Move the selected file to the Trash. There may be one or two other files in the same folder with names that begin in "Calendar Cache". If so, delete those files too.
    Step 2
    Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash as well:
    iPhoto ▹ Empty Trash
    Then reboot. That will temporarily free up some space.
    According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation. You also need enough space left over to allow for growth of your data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
    To locate large files, you can use Spotlight. That method may not find large folders that contain a lot of small files.
    You can more effectively use a tool such as OmniDiskSweeper (ODS) to explore your volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one.
    Deleting files inside an iPhoto or Aperture library will corrupt the library. Any changes to a photo library must be made from within the application that created it. The same goes for Mail files.
    Proceed further only if the problem isn't solved by the above steps.
    ODS can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
    Back up all data now.
    Install ODS in the Applications folder as usual. Quit it if it's running.
    Triple-click the line of text below to select it, then copy the selected text to the Clipboard (command-C):
    sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
    Launch the Terminal 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 Terminal in the icon grid.
    Paste into the Terminal window (command-V). You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
    The application window will open, eventually showing all files in all folders. It may take some minutes for ODS to list all the files.
    I don't recommend that you make a habit of doing this. Don't delete anything while running ODS as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.
    When you're done with ODS, quit it and also quit Terminal.

  • I am a OS10.7.4 user. yesterday i bought a Lacie external hard disk but error message appear said " You cant open the applicant LaCie setup assistant because PowerPC applicants are no longer support". please help me how to connect my mac with Lacie??

    i am a OS10.7.4 user. yesterday i bought a Lacie external hard disk but error message appear said " You cant open the applicant LaCie setup assistant because PowerPC applicants are no longer support". please help me how to connect my mac with Lacie??

    You do not need the Setup Assistant; in fact, you do not need any software on an external hard drive. I have two LaCie's; I erased the drive as soon as I plugged it in. You will need to format it anyway because most hard drives come Windows formatted. So, if you only want to use it with the Mac, highlight it in Disk Utility and choose Mac OS Extended (Journaled) as the format and the GUID Partition scheme under Options. While doing that, it will erase the drive (and get rid of the LaCie software) - once finished, your drive is ready to use for Time Machine or any other backup plans you have for it.

  • Disk Repair Error (Time Machine Partition)

    For the second time, my Time Machine backup partition reports errors when I try to mount it (exists on my external hard drive via USB).
    As soon as I plug in the USB external, I get this error:
    *Disk Repair*
    The disk "Backup" was not repairable by this computer. It is being made available to you with limited functionality. You must back up your data and reformat the disk as soon as possible.
    I tried looking at it through Disk Utility, and I found "Repair Disk" grayed out, and when I click on "Verify Disk", the output is:
    Verifying volume “Backup”
    Checking Journaled HFS Plus volume.
    Checking Extents Overflow file.

    Checking volume information.
    The volume Backup needs to be repaired.
    Error: Filesystem verify or repair failed.
    Its worked fine for about 1.5 months since it did this last. My other partition on the external hard drive has always been fine.
    Any ideas on the causes of this, or how to fix this aside from reformatting every 1.5 months?
    Thanks in advance for your help!

    I've had a very similar problem. When I tried to put Leopard on the first time, it wiped out my hard drive directory... Disk Warrior to the rescue. I then bought a brand new internal SATA drive and an external firewire drive for the back up. I formatted both drives and did a fresh install of Leopard on the internal. So far so good-ish. All other weird Leopard bugs and issues aside for now, I am now getting the error message that my Time Machine backup drive (which has been working fine) is irreparable and needs to be formated as soon as possible.
    I have the back up drive partitioned and the non-Time-Machine-backup partition, that is the normal simply-storage partition is working fine. The Verify Disk Permissions, Repair Disk Permissions, and Repair Disk are greyed out in Disk Utility. Here's what I get when I Verify Disk.
    Verifying volume “G5 Backup”
    Checking Journaled HFS Plus volume.
    Checking Extents Overflow file.
    Checking Catalog file.
    Invalid catalog record type

    Checking Extended Attributes file.

    Checking volume information.
    The volume Scratch appears to be OK.
    Is a re-format of the back up drive my only option? How did this happen? and How can I prevent this from happening again?
    Thanks!

  • Time machine backup error in Mavericks

    I"m getting backup errors in Mavericks when it tries to back up to the Backups.backupdb folder in my 3TB external backup drive.  This happens even when I turn Time Machine off! 
    This is the error I'm getting (taken from the console) when I manually start a time machine backup:
    10/26/13 9:56:39.268 AM com.apple.backupd[18160]: Starting manual backup
    10/26/13 9:56:40.826 AM com.apple.backupd[18160]: Backing up to /dev/disk2s2: /Volumes/Macbook Pro Backup 3TB/Backups.backupdb

    10/26/13 9:56:46.070 AM com.apple.backupd[18160]: Backup failed with error 2: 2
    Has anyone seen this?  At this point, I haven't been able to back up anything after upgrading to Mavericks, and I really don't want to delete the backup folder and start over.
    I thought it might be a permissions problem, so I tried to use the disk utility to verify this.  I wasn't able to select verify or repair disk permissions.  When I tried to verify the disk, I got a 'Live file system repair is not supported' error.  I've never seen this before.
    Any thoughts on all of this?

    I fixed this by hard booting, then repairing the disk.  A restart didn't work. 

  • Startup Disk Full Error - Please help

    Dear ALL,
    I have started to notice recently that when I run Photoshop CS on my Mac OSX Tiger, I am getting the Startup Disk Full error message.
    I have no clue as to how to correctly fix this issue. I looked at my HD and I seem to have 32GB available, which I would have thought would have been ample space. I have started to remove unwanted files and backup to CD large image files. So this should free up some more space. The question is will this be enough to get rid of this issue and is it associated with the amount of HD space on my drive? or would I need to run some script etc? or download/buy some other product to fix this?
    Your help is greatly appreciated.
    Max

    OK I tried Macaroni...and when I tried to work with a TIFF file I get the same Startup Disk is FULL message. The I get an adobe message saying Scratch Disk is FULL.
    Any further suggestions would be appreciated.

  • What do i need to do when i get a startup disk full error?

    What do i need to do when i get a startup disk full error?  I can't update software or use my MacAir at all.

    Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:
    iPhoto ▹ Empty Trash
    Then reboot. That will temporarily free up some space.
    According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation. You also need enough space left over to allow for growth of your data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
    If you're using Time Machine to back up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of files you've recently deleted. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as "Backups." The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself.
    To locate large files, you can use Spotlight. That method may not find large folders that contain a lot of small files.
    You can more effectively use a tool such as OmniDiskSweeper (ODS) to explore your volume and find out what's taking up the space.

  • Adobe Photoshop Scratch Disk Full/Startup Disk Full error - PLEASE HELP

    Dear ALL,
    I have started to notice recently that when I run Photoshop CS on my Mac OSX Tiger, I am getting the Startup Disk Full error message. Never happended before.
    Since my initial post I downloaded Macaroni (utility) and have run the daily/weekly/monthly backups, checked the /private/var/vm and /private/var/log and /Volumes. Nothing unusual there...
    When I started getting this error I had 32GB left on a looked at my HD and I seem to have 32GB available on a 152GB drive. Now after deleting I have 76GB capacity left.
    But when I tried to open a Photoshop PSD or TIFF file and do a crop I still get tge Startup Disk is Full error followed by the Adobe Photoshop error Scratch Disk is Full.
    I am thinking of running the Disk Utility from the Applications/Utilities/Disk Utility and doing a Verify Disk and Verify Disk Permissions followed by Repair Disk Permissions. I will be logged into the machine whilst doing this. Is there any danger in this as I have read elsewhere that I need to do this from a bootable volume. If that is the case how do I create a bootable disk/cd? If not then what is the cure to my Disk Full as surely there is now nearly 50% FREE!!!!!
    Please help.
    Max

    PS will always use the boot disk for scratch to some extent even with an alternate primary scratch disk.
    Be sure to turn off Spotlight as it causes problems.
    4GB of RAM would be nice, I understand small files don't work well if there is more than 4GB RAM but large files will. OS X uses free RAM as cache and RAM disk before using disk drives.
    How much RAM is allocated to PS? More RAM would help.
    A dedicated lean boot drive helps. Install just what is needed for your work, use a separate drive for data, and yet another RAID volume for scratch.
    When in doubt, backup with SuperDuper, and do an erase and then restore. Always backup before repairing; and never, ever, use an old version of Tiger CD/DVD - like 10.4.2 on 10.4.7/.8. Use "fsck" instead, or your emergency boot drive.
    Also, give Applejack a shot and delete the cache folders and swap files from time to time to keep a system humming. CS/CS2 and Tiger benefit nicely from more RAM.

  • G460 Disk Read Error

    Can someone help me, i'm figuring out what caaused this problem and i have so many files in my computer. When i turn it on it doesn't go through the LENOVO screen, then after 2 or 3 minutes it displays Disk Read Error, please press ctrl + alt the delete. the Harddisk light doesn't light up. and it makes a horrible noise. the noise I hear is like a Hard Disk spinning without a disk. 

    it seems your harddisc is dead. ( or possible connector issue )
    if you have external harddisc box, remove your hard and replace into it, test your harddisc.
    if it works, backup your data, replace your harddisc into computer.
    try to re-install operation system. if it doesn't work, call lenovo and ship your computer back to service.

  • IMac won't restart, "Disk full error"

    Shuts down soon after Apple, status wheel and status bar appear during startup. Tried safe mode, etc. and got "disk full error." "Could not be repaired."

    I think the store appointment would be safest.
    Of course, it's unix.
    You need to get into single use mode for steps one and two that are listed below.
    This page will tell you how to get into single user mode.
    http://support.apple.com/kb/HT1492
    Basically, you hold down the command-s key then  powering on your machine. The command key has a little apple symbol on the lower left. It is between the alt/option key and the space bar. On a PC keyboard, it will be the windows key, I think.
    # Type the follow two instructions to access the startup disk in read/write:
    # ( in case of partial success repeat this command until errors go away. )
    /sbin/fsck -fy
    /sbin/mount -uw /
    the delete command is rm. note the file is gone. there is not recovery beside backup

  • Backup error after kernel patch upgrade

    Hi.
    I have a backup problem after the kernel patch upgrade.  I have SAP R3 4.6C on HPUX11.0 with an Oracle 8.17 database.
    I have upgraded kernel patch from 1655 to 2337.
    Afterward, I am getting following backup error:
    BR280I Time stamp 2007-11-06 09.29.01
    BR279E Return code from '/usr/sap/HAD/SYS/exe/run/backint -u HAD -f backup -i /oracle/HAD/sapbackup/.bdwnpztp.lst -t file_online -c': 2
    BR232E 0 of 115 files saved by backup utility
    BR280I Time stamp 2007-11-06 09.29.01
    BR231E Backup utility call failed
    Does anyone know how to correct this?
    Thank you.

    Hi Jun,
    backint is a link file that is in SAP kernel directory which links to the backup client on the server.
    eg:
    lrwxrwxrwx   1 root     other         32 Aug 13  2004 backint -> /usr/openv/netbackup/bin/backint
    As part of kernel upgrade process, the kernel is backed up, mostly on the disk before upgrading. Check if this link exists and recreate it in the kernel directory, if no backup was done, compare it with other systems to get the details of the backint link.
    Cheers,
    Nisch

  • Backup error message

    I cannot solve backup error message. I've tried chkdsk on both internal and external drive to no avail. I have a Pavilion dv6 with windows 8.1. Any suggestions?

    That iTunes backup does the whole library. One idea...not sure if it will work....uncheck the box next to the movie, and maybe it won't try to include it.
    Just a word of caution. Make sure these backups actually work BEFORE you need to use them. I spent hours making almost 30 DVD backups of my itunes library, and when I tested my restore plan, it failed at about disk 12. I have since changed to an external hard drive for more reliable backups of my music.
    Also, if you value your ratings, playlists, etc....back up the itunes database file
    iTunes Library.itl
    Here is a pretty good iLounge article on it.

        # everything looked fine. I would then try to use Disk Utility to repair permissions and end up with a
        # cryptic error that pretty much told me nothing.
        # I noticed that while in Disk Utility, if I selected a partition the lower LH corner of the dialog
        # showed : Owners Enabled : No
        # I tried selecting the partitions at the Desktop and doing a (CMD-I) and at the very bottom of each
        # info dialog there was a checkbox :
        # [ ] ignore ownership of this volume
        # which I would check, even after logging in as root, and I couldn't seem to get a consistent way
        # to get rid of the permissions dialog failure, so I found the vsdbutil command which can be used

    As it turns out, this didn't completely solve the problem, it solved part of the problem.
    Here is a summary to the root cause of the problem.
    SUCCESS...
    Problem Summary : The system crashed and would hangup during boot, tried many things, until I eventually erased the disk and started over again.
    iMacG5 24 GHZ Intel with One internal disk partitioned into 3 logical drives
    Cub_1 OS X 10.5.7
    Cub_2 OS X 10.5.7 (Carbon Copy Cloner backup of Cub_1)
    Cub_3 OS X Server 10.5.7 (standard os x server setup)
    At some point after setting up standard preferences, OS X Server crashed.
    When I tried to restart, the machine would hang up during boot.
    Finally after several attempts, ran Disk Utility from install dvd and repaired Cub_3
    When I tried to run "Repair Permissions" on Cub_3 from install dvd, I got an error
    Disk Utility Error: The underlying task reported failure on exit 1.
    Rebooted, and started in single user mode (CMD-S) during boot until I saw the unix commands on the screen
    RAN : root # fsck -fy
    Then I began seeing the same command filling the screen :
    posix_spawnp("/usr/sbin/mDNSResponder") could not find file or directory
    Called Enterprise Support and spoke to Frank Alcorn, he said this was most likely a permissions problem and asked me to try repairing permissions from the install dvd. I told him about the error, but nevertheless I tried it again and got the same Disk Utility Error: The underlying task reported failure on exit 1..
    He asked me to try booting into single user mode again, and to try
    root # chmod 775 /
    root # reboot
    During the reboot process the machine got hung up again, and could not get the single user mode to work at all.
    Frank said the command needed to be :
    root # chmod 1775 /
    Frank asked me if I had changed anything in file sharing, and I told him I had. He asked me what I had shared, and I said the entire drive Cub_3. He asked me what I had done for permissions, if I had denied permissions to anyone. I told him that I had set myself up as the only user that could have access to it, and when he said that's where the problem was the lightbulb went off, and it made sense.
    Shortly after I set the sharing preferences is when the server crashed. It all makes sense now...
    Frank said not to share the entire disk, only portions (share points) of it. I had done this in Panther Server, and Tiger Server and it worked fine, but apparently Leopard Server works a little differently, maybe more secure.
    It seems to me that if sharing the entire disk, which is what I needed would cause such a problem there should have been some sort of warning from the operating system, but there wasn't. I had run into this problem several times over the past three weeks since I had started working with Leopard Server, but in each case I ended up re-installing OS X Server and starting over again.
    I told him I would try to reboot from the OS X partition (Cub_1) and try it from there.
    He asked me to let him know if it worked, and I said I would...
    Problem FIX :
    I booted back into the partition containing OS X (Cub_1) and did the following via the Terminal.
    $ su - root
    $ chmod 1775 /
    $ reboot
    During the reboot process I held down the (OPTION) key, and selected Cub_3 (the os x server partition) and sure enough after a few minutes of holding my breath the login window magically appeared. So I logged in, and did not have to re-install the server. Hallellujah....
    This solved the boot hang problem. It is great to finally have an answer. In retrospect it makes sense, but that's why its hindsight...
    The reason for sharing the entire disk in my mind was that since I was the only user on the system, it was easier to have one disk mounted on my workstation rather than several folders. It made sense to me, it still does. I don't need a bunch of folders, just one disk is easier...

  • What do I do about disk ejection error when resuming from sleep?

    Hi folks,
    I have a FW800 2.5" HDD (powered through FW port).
    When I close the lid on my computer it goes to sleep. If I leave it that way for a longer period of time, I get the disk was not ejected properly error when I bring the computer out of sleep. I am not sure how long it takes, as I've not sat here testing different time periods. But I do know that if I just hit sleep in the APPLE menu, the computer sleeps fine. I can then bring it out of sleep and HardwareGrowl shows me the (pre-sleep) Device Disconnected message and then the post sleep Device Reconnected message. I get know error.
    I don'k think I should have to manually eject my HDD each time I wish to talk away from the computer for an extended period, yet I am wondering if this disk eject error is something to be concerned about. The disk is formatted in Mac Extended Journalling.
    With thanks,
    Jonathan

    Alright, I'm slowly getting ready to do this. Apparently I do not need an install DVD but I can just press CMD+R to get to the option to do a fresh install, that's why my Mac didn't come with an install DVD (that's what I've read and what I've been told at least).
    Now I'm wondering... do I need to copy those items from the User folder at all? I mean, I have a complete backup on an external hard drive. I could just go there in the folders and select what I would like to copy to my Mac again, suchs as my music library or photo library. Is there any risks? I'm worried about even the smallest things, like creation dates changing and stuff like this. They mean something to me
