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...

Power outage caused display issue

we had a power outage that shut off the computer. After unplugging it until the power came back on; we found that when we turned the computer on the display just showed several 4" squares across the screen. The computer seems to have functionality still, but you can't read anything on the screen, it's as if the screen resolution is 7 blocks by 5 on the 20" screen.

Let's try to fix the other account.
Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions.
Move these files to the Desktop for now...
/Users/YourUserName/Library/Preferences/ByHost/com.apple.HIToolbox.<12digitHexNu mber>.plist
/Users/YourUserName/Library/Preferences/.GlobalPreferences.plist
/Users/YourUserName/Library/Preferences/com.apple.systempreferences.plist
/Users/<yourname>/Library/Preferences/ com.apple.systemuiserver.plist
/Users/<yourname>/Library/Preferences/ByHost/com.apple.systemuiserver.xxx.plist
where 'xxx' is a 12 digit (hexadecimal) numeric string.
/Users/YourUserName/Library/Preferences/com.apple.finder.plist
/Users/YourUserName/Library/Preferences/com.apple.desktop.plist
/Users/YourUserName/Library/Preferences/com.apple.recentitems.plist
Reboot & test.
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.

Power outage - HDD Problem - How to reinstall without disc drive?

Hi there,
due to a power outage the journalling of the hdd of the mac mini server running Snow Leopard Server is corrupt and repairing was impossible. I've got to reinstall the system now somehow, but the mac mini doesn't come with a disc drive. I tried to create a bootable USB stick but that didn't work for the server version of Snow Leopard. I really need help with this ... Any ideas?
Regards,
Dave

Thanks iToaster, I already did that to access the data on the hard drive, but I can't install Snow Leopard Server via Target Disk Mode, can I? If yes, how?

Thinkpad Power manager causing problems in Vista

Hi,
We have been having problems with the Thinkpad power manager (all versions that we've tried) on Vista with T400, T500, and T60 series laptops. These problems range from the program crashing to blue screens and reboots. If we remove the software and use Vista's built in power manager, the battery life gets cut in half but we do not have any problems. Has anyone else had these problems? Is there a way to reliably increase the battery life using Vista's built in power manager? If not, how can we get the thinkpad power manager working correctly?
Thank you,
Brandon

Power Outage caused server crash

A breaker flipped and caused both our dhcp and zenworks server to go offline. My main concern right now is getting the internet back up and running. I logged into Sles and we're running oes2. I don't know if I need to restart a service or what, but the server is displaying that there is a log file for viewing I assume? Any help is greatly appreciated as I can't solve this problem on my own.
Thanks,
Ryan

some additional tips:
One file I also always check after (re)booting a server is the /var/log/boot.msg. The last lines normally show which services were skipped (normal if there is nothing to do or configured for a service) or failed (which is a first indicator if " stuff" isn't working after bootup).
To get the last lines of that file, use the tail command;
#tail /var/log/boot.msg
Another usefull function of that tail command, is to a get a realtime/feed on a file, like the /var/log/messages;
#tail -f /var/log/messages
Or you can combine it with grep to only show lines with a specific content, like messages given by dhcpd;
#tail -f /var/log/messages|grep dhcpd
Before restarting a service, it's often good to check the current state of a service;
#service [servicename] status
(the service command is the same as using rc[servicename] [action], I find it a more logical way to handle services)
The great thing about Linux is that you can do most things using a ssh console connection. It just takes a little time and practice finding all the (often built in) tools you need/prefer.

Power outage caused laptop not to boot anymore

I had my hp Pavillion dv9000 connected directly to the wall without the battery inside and was watching a movie. The power outlet suddenly died and consecquently my laptop turned off. Now when I try to turn it on, the fan runs but nothing shows up on the screen; not even the hp logo or BIOS. I noticed that the hard drive access LED never lit up so I assume it wasn't just the screen that broke but something is causing the whole computer not to boot up at all. Most likely something got fried but I'm not sure what. It's a shame because I really liked that laptop and would like to repair it if possible. Does anyone have any suggestion?

Hello NTHQ,
Sorry to hear you are having trouble with your HP notebook powering on.
I have looked for information on your system and I do have a suggestion for you that might be helpful.
You should check and see if you are getting a blink code from the caps lock and num lock keys.
Here is a link explaining the blink codes.
Can you provide your full model and product number? Here is a link showing how to find that information.
Let me know what happens.

Power outage caused invalid date on computer

The power went out and when I next tried to start my mom's computer the finder couldn't find itself with the invalid date and time. I've tried going to prefs to reset clock/date but all is greyed out and the little rainbow wonder ball just keeps spinning. I've tried opening an application & going to systems prefs from there with the same result.

Power Outage & iPod

I had a power outage caused by a sever thunderstorm today around 5:30 pm and as soon as the power came on. I connected the iPod and iTunes ran a test on it and a message saying”iTunes has detected a corrupted iPod the IPod has to be reformatted to be used by iTunes” then another message after clicking ok said”there was problem downloading the iPod software “iPod” the request resource was not found" and right now it’s current state is frozen is there a way this can be fixed?.

Hi weatherscience!
Have you first tried resetting your iPod? To reset an iPod:
First, toggle your iPod's "Hold" switch back and forth a couple of times. (be sure to leave it on the white side of the switch, which is the Off position)
Next, press and hold the Menu and center buttons together for 5-10 seconds.
You might need to try this several times. Also, attempt this step both while connected to your computer's USB port, and disconnected.
Try restoring your iPod in iTunes again. Do you still get that "requested resource" error?
If so, then let's try forcing your iPod into disk mode. For instructions on how to do that, see this Knowledge Base article:
Putting iPod into disk mode
Also, if that doens't seem to be helping, you could try all of the five iPod troubleshooting steps, here:

865PE Neo2-PFISR problems after power outage

I need some help with a problem. A recent power outage while my supposedly "surge protected" 865PE Neo2 based machine was running, apparently messed something up. After our power came back on, I powered it back up and discovered that I now have 4 ongoing problems. Problem 1) it now hangs twice during the boot process, once at "auto detect 3rd master - press escape to abort", which if I then press ESC, it then moves to "auto detect 3rd slave - press escape to abort" and hangs there until I press ESC, at which time it then finishes booting like normal. (by the way, I don't even have any 3rd master or 3rd slave installed) Problem 2) I can no longer enter the Bios setup, even though I press the DEL key at the appropriate time. Problem 3) The case light for hard drive activity stays on constantly, even though the drive seems to be working normally without any other problems. Problem 4) A few issues here. My sata dvd/cd combo drive is no longer recognized as being installed; the activity light on the drive is constantly on even though the drive is not running; the drive bay will no longer open.
I'm guessing that something has possibly been damaged on the motherboard or maybe the bios was affected somehow, or maybe the power supply was somehow damaged. Either way, I'm not sure what to do now. With the exception of the problems I listed, my system otherwise works normally as it always has, with the only real downside being that I don't currently have a dvd/cd drive. I haven't tried any troubleshooting myself because I'm not sure where to look or what to look for. The specs for my system are listed in my signature, with the only change being that I'm still running the original Antec 350w power supply that came with the case. I could sure use some expert advice and help with this.

Problem Update.
Well, I finally got my machine up and running "almost" as good as it was before my power surge problems. Thank you to everyone that responded with advice. I ended up replacing the Antec 330w TruePower psu with the new Enermax Noisetaker 420w (EG425P-VE SFMA V2.0) that I had, and I had to replace the MSI sata combo drive (went with a Pioneer 710 DVD-RW, which is an excellent unit) and now things are back to normal. Plus, I bought an APC 650VA/390watt battery backup with soft shutdown to help prevent any power outage problems again.
When I said "almost" as good as new, that is because this morning when I booted up, all I got was a black screen (no post) for a couple of minutes, and then a message appeared that approximately said "the dram timings are too tight, reload timings", or something like that. Well, since the timings have never been changed, I'm not sure what is going on, but after turning it off and then re-powering it up again, it booted (though slowly at first) and I've just been letting it run all day. Ha, just when I was ready to venture into OCing this rig. Think I will anyway. If the problem continues, I'll be back seeking helpful advice again.

After several power outages, there is only a white screen, an apple in the center and a time strip after the strip is complete it turns it self off what is this problem

I have a 27in Mac desk top, its about a 2009, after several power outages and the computer pluged up and on now when turn it on it shows a white screen, apple in the center and a time strip toward the bottom when the time strip goes to the end of the cycle it shuts its self off.
The only thing we have tryed which was from a forum which was simular problem was, command-option-p-r, hold them down til the screen was back up, we try several times it did not work, please,please some-one help we use this computer for our job.

Also the trick you used, is known as resetting the PRAM. Not always the best of ideas for Macs older than 4 years. But I'm glad it worked for you. There is a battery which will eventually need replacing inside that would actually make that technique stop your Mac from working until replaced.

Does any one know about the small Hardrive that "The Power Company" is producing, sponsored by Indiegogo, for small Apple mobile devices (iPhones, iPods, etc,). Do they work or cause problems for the device or iCloud storage?

Does any one about the small hard drive that "the Power Company" is bringing out as a crowdsourced project by Indiegogo? Does it work, does it cause problems for IOS, iPOD Touch or iCloud?

I have not heard that mentioned here before. What does the Indiegogo page say?

Power outage - help fixing problems

Happy New Year All,
Follwoing a sudden local power outage, my iMac (Late 2011, OS X Mountain Lion) restarted OK and I was able to continue working.
Two problems remain.
1. I use an online backup service (JustCloud) which was running at the time of the power outage but now the application will not start showing the error message "...cannot start as there is already another instance running on this computer". How do I fix this problem please?
2. Despite the "Open windows on restart" box NOT being checked, a Safari window opens automatically on startup / login. Again, any thoughts on how to fix this.
Many thanks in advance

Thanks for the tip.
The problem was that the process was not showing in Activity Monitor - or at least it wasn't obvious what the process was called as it certainly wasn't called JustCloud!
Anyway, after an overnight rest I logged onto a different account on the iMac and all seemed well. I thne logged back into my own account and tadah - all working OK.
I have repaired disk permissions and rset safari in any case and JustCloud is backing up as I type.
Thanks for your response in any case - much apprecaited

Problems erasing HDD after power outage.

Sold my old MacBook Pro and want to erase the HDD. While erasing the HDD during the night I had a power outage and the MacBook ran out of battery before completing the task. I can't resume the erase since the HDD will not unmount. Any suggestions would be greatly appreciated. ThanksProblems

You erased it. Of course it will not mount. While it may not have removed all the 1's and 0's you put on it, it got well paste the beginning of the disk where the file system superblock was located, so as far as Mac OS X is concerned, there is no valid file system on this disk.
Can you use Disk Utility -> Select the disk -> erase tab -> erase button, and erase the physical disk that way.
