Mac Mini wont start after power outage, and problem copying iPhoto library. HELP!

    So, recently there was a power outage in my neighborhood, the power was intermitent for about 2 hours, during this time my mac rebooted itself several times, but on the second time it rebooted the power went out during boot, then the power finally went out for good, it was back in about 3 hours, but when i finnaly turned on my mac it got stuck at the Apple logo with a spinning wheel and a progress bar that wouldnt go past 40%, when i boot holding command -v it said that there were a lot of errors which were automatically fixed, except for one, "Incorrect Thread records" or something like that.
    I have another partition with Mountain Lion installed for emergencies, the other one with Lion became inaccessible to mountain lion or any other OS X version, but oddly enough, I can access my Lion partition via HFSexplorer and see all my files untouched.
    My main concern are my pictures in iPhoto, and thats about 36Gb of data, I want to backup them to my windows pc by copying the whole iPhoto library package, but HFSexplores for some reason cant copy the folders with date (XX/XX/XXXX) with the /, and it keeps changing them to XX_XX_XXXX and I know that would pretty much break my iPhoto library!
I googled my drive problem and people said that I need a Disk Utility called DiskWarrior, but I cant seem to find how to to use it, I got a copy from a friend, it was the digital version of the boot disk which need to be burned to a dvd.
Any help would be appreciated, and sorry for the bad english

OK, we need more info about your Mac. Do you know how much RAM it has in it?
If you don't know the model, find the Serial# & use it on one of these sites, but don't post the Serial# here...

  • Hyper-V manager will not start after power outage and memory corruption

    We suffered a 2 hour power outage and upon power restoration I had a corrupted memory strip. replaced memory and cannot start Hyper-V manager due to lost mmc file or does not exist. virtual machines are running fine I just can't manage or create any additional.
    This is on win server 2012.
    Anybody....Please Help!!!@!@!

    Try:
    Add-WindowsFeature -Name Hyper-V-Tools
    This installs the Hyper-V Manager GUI tool only.
    If that does not repair it, try:

  • Intel mac mini wont boot after system restore

    Hi,
    I ran the system restore on my intel mac mini using the genuine leopard cd that came with it.
    Now it wont boot. When you press power the light comes on but it does not chime and there is not video output to any monitor.
    Anyone know what could be wrong?

    Welcome to Apple Discussions!
    You picked 10.4.1 in your profile.
    Intel Mac Minis at minimum came with 10.4.4.
    If it came with a 10.5 genuine DVD, it most certainly was not running 10.4.1 or 10.4.4. Perhaps you mistook one Mac Mini install DVD for another? Does your Mac Mini have 4 USB ports on back? What does the 10.5 installer disc you used look like?

  • Computer won't start after power outage

    After a circuit breaker was shut off the computer won't start. I cleaned out the computer and got the light to go green by putting a hair dryer to it.
    When I push start button and hold it up to 10 seconds it will not start.
    The computer is a compaq presario sr5130nx

    Typically what happens during a power outage is not good.  It can do strange things.  If it took using a hair dryer to get the green light on the back to come on, that is a bad sign.  HERE is a troubleshooting guide for power supplies.  Start with that.

  • Mac Mini repeatedly getting "Press power button and restart your computer"

    I keeping getting the following message coming up on my Mac Mini "Press power button and restart your computer". I have a G4 Mac mini and it boots up fine and runs ok for about 10 mins however after that time (if left) the message comes up. I restart the machine and the same thing happens again.

    Isolate the cause as my FAQ suggests. Backup, or recover your data first*

    and then discover if the issue is hardware, a directory, or software.

  • MacMini PPC not starting after power outage

    MacMini PPC running Leopard - plugged into a UPS & power strip with a surge protector - it was running last night when the power went out in our area - this morning it won't boot up - get the chime the Apple logo & the spinning clock - can hear the usual startup sounds but a few seconds later it shuts down - inserted the install disk & held the option key - it showed the internal harddrive (with a blue X), the external harddrive with the SuperDuper backup (with a blue X), the install CD (with a blue X) & the Apple Hardware Test, although the mouse works the pointer remains a clock & after a few seconds it shuts down - any ideas or suggestions ? - the Mini acts as our wifi source so am off line except for the iPhone

    I take it that the power outage was long enough to deplete the UPS and that the Mini therefore had its power pulled abruptly when the UPS ran out of juice?
    Since you have a PPC Mini, you can try a PMU reset. (This is only PPC Minis; don't use it if you have an Intel Mini. Intels get the SMC reset.)

  • Mac min wont start

    gray screen comes up with the apple and the loader symbol spins but just does not come in, few days before i was having issues with the drive and graphics, is this a goner?
    it is a g4 1.5 512mb superdrive model

    If the drive is clicking, it may be defective, which could affect startup: I've had several G4 towers refuse to boot if the optical drive was dead, even with no disk in the drive.
    Can you boot to single-user mode (hold apple+s keys on startup)? If so, use the "fsck -fy" command to run file system check (Repair Disk).
    Another thing to try, if you have access to another Mac, is to start your mini in Target mode and see whether it mounts when you connect it via firewire to another Mac. If it mounts, you can try running Disk Utility and see whether that helps.

  • Mac Mini - Screensaver starting on its own and clock is fast ...

    Hi there experts ....
    I've got a 4 month old Mac mini
    Model Identifier: Macmini3,1
    Processor Name: Intel Core 2 Duo
    Processor Speed: 2.53 GHz
    I've noticed for the past couple of months the clock is 4 minutes fast ....
    And the screeensaver is coming on by itself out of nowhere ...
    I/ve run disk repair ... Maintenance ... put screensaver to never and even disabled front row screensaver
    I've reset pram and nvram ... ANy clues ....?

    So even if you put the screensaver to never it still starts on its own?
    Also you clock runs faster by 4mins?
    I smell an OS issue. Partition your drive and install a fresh OS onto it. If it works(no problem there) then restore the partition into 1 drive. Zero out the drive and put a fresh OS in it
    **back it up first
    If the fresh OS on the new partition still fails. it could be a hardware failure.

  • TS1717 iTunes not starting after power fail and reinstall

    I'm using a Samsung NP700 series laptop, with a dodgy battery, running Windows 7.
    I was doing some work when the power failed and my battery failed soon after. When power was restored the system ran CHDISK during boot up and found several problems. I then started getting Win32 exceptions from CFNetwork.dll during start up and whenever I tried to start iTunes.
    I followed the advice in the support pages and ended up doing a complete clean and reinstall. After this the exception had gone but iTunes failed to start. I got nothing, double click the icon nothing, open iTunes from the start menu, nothing. No reports, no errors it just failed to do anything.
    I had installed the 64 bit version but it wanted to install in 'program files (X86)'. Was this the problem?
    In desperation I ran iTunes using 'Troubleshoot Compatibility' that suggested XP SP2 mode and it worked. iTunes complained about being in compatibility but it ran.
    Switching off compatibility mode reverts back to iTunes not bothering to start.
    Oddly enough iTunes remembers that I was using an external drive for my library, I had expected to have to set that up again after the clean uninstall.
    Still I am working, iTunes is not happy but I am working. In the next few days I hope to upgrade to Windows 8 - only God knows what problems that will cause.

    Okay, things have gone from bad to worse. I checked the event log again after another failure to start and found that iTunes hadn't started because of an exception thrown by AUDIOSES.DLL. Sfc failed to fix it so I tried a restore to an earlier date.
    That's when things went badly wrong. After the restore my system refused to boot. Even the recovery disk failed. Fortunately I was preparing to upgrade my system to Windows 8 and already had the upgrade disk.
    One clean upgrade to Windows 8 later and my computer is working again. All I have to do is install all my software again. This is not a big problem as I like to do this every so often to clear out the junk. Haven't got around to iTunes yet (still doing BIOS, drivers and firewall etc first). Hopefully I will be all back to normal in a couple of days. Good job that I am retired.

  • Lumia 625 wont start after power off!

    I bought a lumia 625  5 months ago and it worked fine. but recently when i switch off power it wont turn back on. So i had do keep it in air plane mode at night.   After like one hour it switches on back. I tried resetting and restarting. Phone only vibrates after i release power key ( in all resetting methods), but does not show anything in the display. How can i fix this. help would be appreciated

    I'm going to suggest a hard reset of the phone.  Do a backup first, then either go to Settings/About and select Reset my Phone, or for the 625:
    Warning! All data will be lost!
    1.Power off your phone
    2.Press power button and after phone vibrates once press volume down until you will see exclamation sign on the screen
    3.Press in this order:volume up
                                   volume down
                                   power
                                   volume down
    4.Wait until format ends and the phone restarts
    I'm thinking that something with the sleep mode has gotten corrupted in memory.  If this doesn't clear the problem, then you likely have a hardware/firmware fault and the phone should be taken in for repair or replacement.

  • New Mac Mini wont boot after OS upgrade

    I bought a Mac Mini Yesterday i7 1tb disk
    Wire keyboard and track thingie
    my first mac
    First decided to upgrade OS to latest version
    Its been 24 hours and I have not gotten past the grey screen with these 2 spinnung wheels
    Dave

    Take each of these steps that you haven't already tried. Stop when the problem is resolved.
    Step 1
    The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.   
    There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
        a. Boot into Recovery by holding down the key combination command-R at the startup chime, or from a local Time Machine backup volume (option key at startup.) Release the keys when you see a gray screen with a spinning dial. When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
    How to back up and restore your files
    b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
    How to use and troubleshoot FireWire target disk mode
    c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
    Step 2
    Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
    If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
    Step 3
    Boot in safe mode.* The instructions provided by Apple are as follows:
    Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
    When you see the gray Apple logo, release the shift key.
    If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    *Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Post for further instructions.
    When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.
    If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
    If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
    Step 4
    Sometimes a boot failure can be resolved by resetting the NVRAM.
    Step 5
    Launch Disk Utility in Recovery mode (see step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
    This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
    Step 6
    Boot into Recovery again. When the OS X Utilities screen appears, follow the prompts to reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
    Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
    Step 7
    Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a backup.
    Step 8
    A dead logic-board battery in a Mac Pro can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
    Step 9
    If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.

  • Help! P6N wont boot after power outage.

      We had a power outage this morning and after the power was restored I reset my UPS. Now my system is almost dead. The only indications of life are that the HD access light, and the power light flash at a 1 Hz rate. I tried resetting the BIOS (SW3), but no change.
    Motherboard: MSI7320 (P6N)
    CPU: Intel Q6600
    RAM: 4Gb OCZ Platinum

    try with a different power supply first.
    remove all components...
    test a RAM stick by stick a time
    left it boot only with minimal processor, a stick of ram and a graphic, maybe if you have.
    you can leave not to put your hard disk / optical devices at a moment.

  • Unable to get my tabs back after power outage and "restore previous session" doesn't show up.

    Well, I've spent most of my day trying to figure out how to fix this. My power unexpectedly went out overnight and I left my computer on. When I woke up, i saw that the computer was off. So I started my computer, but when I went to get onto Firefox, none of my windows and tabs were there. (and I did have a ton of tabs open.) There wasn't even a "Restore Previous Session" icon to press on the Firefox homepage or a "Well, this is embarrassing" window. I tried opening "sessionstore.js" and "sessionstore.bak", but then a window came up titled "Windows Script Host" and said "Microsoft JScript Compilation Error." Then all there is to do is press "Ok". (By the way, at another time today when I tried opening a .js file, it said "Windows can't open this file" and it wanted me to choose the program I wanted to use to open the file, or use the internet to find a program. I chose Notepad, but then it was just a bunch of letters, words and symbols.)
    I've also tried entering "about:sessionrestore" to get my windows and tabs back and then it says "Well, this is embarrassing." and "Firefox is having trouble recovering your windows and tabs." And there are no windows and tabs showing up below that sentence, with check marks, like it is when session restore has worked for me in the past. The only thing that worries me is that I did restart my computer between when I first started it this morning and now, when I'm writing this. I wanted to see if the "Restore Previous Session" icon would bring up my missing windows and tabs from before. But all it brought up automatically were the current windows and tabs that I have open right now. So now I'm wondering if I've permanently lost those tons of tabs that I had open before the power went out.
    The other thing is that when I first got onto Firefox today, I could see all of my history from the days, weeks, and months past. Now I can only see today's history. I know I pressed something when I was trying to fix things but I don't remember what I pressed. Maybe that changed whether or not I could see the previous months' history. I did try "places.sqlite", "places.sqlite-shm" and "places.sqlite-wal" to restore my history, but again it said "Windows can't open this file" and it wanted me to choose a program to open the file. So again I chose Notepad, and it was just a bunch of letters, numbers, and symbols.
    Hopefully someone may have an answer for me. Thanks!

    Yes I can understand you being confused there is an awful lot of information you need to take in and learn as you encounter such a situation. I will try to expand my explanation to cover the points you ask.
    ''right click the file and select "restore previous versions", right?''
    That is correct when using Windows to try to recover for instance files where the working fie is corrupted, but a previous version worked
    If you have no previous versions available from Windows you need to work on whatever you do have. With any file restore operation it is always a good idea to make copies of not only the originals but also the restored files.
    If you restored the ''places.sqlite'' with Windows that could possibly have resulted in a copy overwriting your working file that is even worse than the original file.
    When you restore a file using the Windows OS it restores the files in their ordinary working location and they should function as expected without needing to do anything else. Generally it is probably best to try such restores when the files are not in use and in this instance that means when Firefox is closed.
    For the benefit of any other readers of this thread note : <br />The places.sqlite is in the Firefox profile and easiest to find before closing down Firefox as the ''troubleshooting information page'' (''about:support'') may be used to find it.
    * [[Profiles - Where Firefox stores your bookmarks, passwords and other user data#w_how-do-i-find-my-profile]]_how-do-i-find-my-profile
    The ''places.sqlite'' database is the only file Firefox itself has with the full ''History'' information in it. The database also contains bookmarks but Firefox should have some other backups of those. If the database is deleted Firefox will restore the database but all it can do is add back bookmarks information from its backups the History is lost.
    There is almost no chance of getting the History back unless there is another copy of that database. Either one Windows is able to recreate, or one that was somehow created by another method, that normally being the user deliberately making a manual backup of your profile or places file in advance. Or maybe having in place other backup procedures.
    '' am I supposed to double-click the file?''
    That is not going to help in these circumstances. There are advanced methods of studying the files but right clicking does not help in this instance.
    Open tabs information is stored in the series of files ''sessionstore.*'' It may take rather a lot of messing about to to get any useful information out of whatever files you have. It would normally probably be a lot quicker just going back to the sites concerned, but that is made more difficult if you have overwritten the History database so you may need to try if the tabs were important to you. I can give more details in another post if you need to try that
    We could have a lot more luck with your bookmarks. Did you bookmark most of the sites concerned ? If so then at least you have a good chance of finding the sites again.
    Have you already got a fairly complete listing of your bookmarks in the Firefox bookmarks library/menu ? If you need to try to get back lost bookmarks that existed in the last few days but not are not present right now make a backup copy
    *Of the profile folder called '''''bookmarkbackups''''' ( With its contents ! )
    * ''places.sqlite'' Remember whenever attempting restoring bookmarks always backup the database file ''places.sqlite'' first.

  • Hyper-V Host displays error "Automatic Reapir Failed" and will not start after Power Outage

    I have a single Dell PowerEdge configured as a Hyper-V host running Wink12 R2 Preview as a Native Boot VHD and hosting about a dozen VM's. We had a break in the power, just a lights on lights off, but it was enough to shut the machine down and trigger restart.
    But the machine won't restart--instead it displays a message "Automatic repair Failed" and none of the Advanced repair options work to get the host back online.
    Any assistance is greatly appreciated.
    Michael J. Murphy

    Hi MJMurphy,
    Sorry for the delay , it seems likely a disk problem cause of unexpect interrupt .
    Please boot the host from OS ISO and  try to copy the VMs' VHD files and any important data to a safe place (such as external USB)via command prompt mode  .
    (perhaps you need to prepare raid driver if you have a raid controler  )
    Using diskpart --> list volume to check the status of disk partion or you can contact the hardware vendor to check it .
    Hope this helps
