I have a

iMac (24-inch Mid 2007), this is the second time that I had to replace our Hard Drive.  So, we went in, had a new one installed, they recovered all of my data however, when we turn off the computer and turn it back on it sits on this white screen for five mins or so and then it starts up just fine.  I want to know why it is sitting ont his White screen and taking this long to start up?  Also noticed they had turned one our airport mode? Any reason why that would need to be on?

 



iMac, Mac OS X (10.5.8)

    Try this:

     

    1. Turn off Airport if it isn't needed.
    2. Open Startup Disk, select your boot volume, click on the Restart button.
    3. Repair the hard drive and permissions: Repair the Hard Drive and Permissions

     

    Boot from your Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.

     

    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.


     

    Kappy's Personal Suggestions for OS X Maintenance

     

    For disk repairs use Disk Utility.  For situations DU cannot handle the best third-party utilities are: Disk Warrior;  DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible. TechTool Pro provides additional repair options including file repair and recovery, system diagnostics, and disk defragmentation.  TechTool Pro 4.5.1 or higher are Intel Mac compatible;  Drive Genius is similar to TechTool Pro in terms of the various repair services provided.  Versions 1.5.1 or later are Intel Mac compatible.

     

    OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep.  Dependence upon third-party utilities to run the periodic maintenance scripts had been significantly reduced in Tiger and Leopard.  These utilities have limited or no functionality with Snow Leopard and should not be installed.

     

    OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems.

     

    I would also recommend downloading the shareware utility TinkerTool System that you can use for periodic maintenance such as removing old logfiles and archives, clearing caches, etc.  Other utilities are also available such as Onyx, Leopard Cache Cleaner, CockTail, and Xupport, for example.

     

    For emergency repairs install the freeware utility Applejack.  If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the commandline.  Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard.

     

    When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.

     

    Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):

     

    Backuplist

    Carbon Copy Cloner

    Data Backup

    Deja Vu

    iBackup

    JaBack

    Silver Keeper

    MimMac

    Retrospect

    Super Flexible File Synchronizer

    SuperDuper!

    Synchronize Pro! X

    SyncTwoFolders

    Synk Pro

    Synk Standard

    Tri-Backup

     

    Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.

    Hi!  Ok, when you say boot volume do you mean the Mac OS X 10.5.8 on Mac HD?  They had Network Startup Selected.  Why would one need to have Network Startup?

  • Kappy Level 10 Level 10 (247,285 points)

    That's what they must have used to reinstall on the new drive. Probably the delay was due to that. You want to select the volume from which you normally startup like "Mac HD" or "Macintosh HD."
