Power surge file recovery

I was working on a file n flash that had recently been saved
when the power surged and the power was lost briefly. We had to
restart teh servers that the file was locaed on. After doing that,
I see the file on the servr and it looks like it has the
appropriate file size (similar to earlier versions of the file) so
it is there, but flash (8) says "failed to open document" when I
try to open it. It will only open an earlier named version from
that morning. Is there any way to get that file to open? Or is ther
another progam that might check it for something damaged? Could it
really fry a file that was saved because it was pen during the
surge?
Help.

We see this same issue almost weekly here - it is always with
people working/saving to a network
drive - it has always been not the best practice - for any
kind of file and program. Simply put -
never work/save to a network if you can help it - any hiccup
in connection or power loss will result
in a loss of work and potential file corruption.
Always save locally and *copy* to a network drive for sharing
and backup purposes.
I know this doesnt help but your file is lost forever.
next time, if this happens - *do not close the file in flash*
- copy all frames and paste into a
*new* fla and save it locally.

In the process of saving a file a power surge rebooted computer. Any chance of recovering file?

In the process of saving a file a power surge rebooted computer. Any chance of recovering file?

Have a look at the sample script below. The "while" loop waits for the specified number of milliseconds, then reads the contents of a directory and processes every individual file in the directory. In my example, it just prints the file path to the console. You would replace this part with your Open / Save as / Move sequence.
For more file system commands, refer to Adobe's Javascript Tools Guide, "File object functions".
var stop = false;
while( stop==false ) {
    // Wait for 20.000 ms
    $.sleep(20000);
    var fld = new Folder("c:/incoming");
    var filesInFld = fld.getFiles("*.fm");
    for(var f=0; f < filesInFld.length; f++) {
        // process the individual file
        $.writeln(filesInFld[f]);
    // Exit the loop after 19:00
    var time = new Date();
    if( time.getHours() > 19 ) stop = true;

Power Surge Fried It- Can I save my files?

My iBook was fried by a power surge yesterday. Wont turn on.
I was wondering if its still possible to save my files if I take it somewhere?? Or even to get the computer running again. I mostly just want my files as I was planning on buying an iMac soon anyways.
Thanks!

Oh, bad luck! If the iBook won't turn on I doubt that anything can be done re saving the computer. Wait for a few more replies before taking that as gospel though...
In the meantime you can try a PMU reset:
1. If the computer is on, turn it off.
2. Reset the power manager by simultaneously pressing and then releasing Shift-Control-Option-Power on the keyboard. Do not press the fn (Function) key while using this combination of keystrokes.
3. Wait 5 seconds.
4. Press the Power button to restart the iBook
What you can do is to remove the HD and put it into an external enclosure. Once you have your new iMac you can connect the two and transfer what files you want.
For instructions on removing the HD select your model Here then Hard Drive on the next page.
If you're planning to sell the remains as a 'spares or repair', perhaps on eBay, you need to be fairly careful and put it all back together again. Otherwise you can be as destructive as you like until you get to the HD.

Can power surges corrupt files?

I have a 2 Ghz rev. B iMac that every month or so, gets corrupted files that cause it to hang, both during use, and in start-up. It's worse when the computer wakes from sleep (hangs if I try to even move the cursor too soon after waking) and not as often if I set the computer to never sleep. It rarely boots up completely after an unexpected shutdown. Disk Warrior has kept it running, but it has to rebuild the directory every time, and sometimes I have to do an archive and install before the computer will run normally again. Once I had to do a clean install because the partition was corrupted. Running the extended hardware test reveals nothing. It doesn't run hot at all, and I have plenty of RAM.
I posted this problem before, and was advised it might be the hard drive, but since this has been more of an annoyance than any real threat, I haven't looked into a replacement yet. So I have three questions:
1. Does this indeed sound like a typical hard drive problem?
2. If I change the hard drive myself, does that invalidate the Applecare warranty?
3. Could small power surges have caused this corruption over time? Because I notice room lights sometimes dim when I turn on the TV or ceiling fan. I have since started using a Backup battery supply for the iMac.
Thanks in advance for any help, and sorry for its length.
G5 iMac 2.0 Ghz Rev.B Mac OS X (10.4)

Thanks for the input. I do have one further question regarding the logic board.
After fixing the directory with DiskWarrior and doing an archive and install, the iMac will run perfectly for about a month before suddenly slowing down and hanging with the spinning beach ball if I even move the cursor. Do logic board problems pop up this way, after an extended time of running normally, or are they more constant? I'm trying to narrow the possible causes as much as possible before talking to Apple.
Thanks again.

Won't let me copy to hard drive post power surge

Ok, to make a long story short, I hope, I had an electrical fire (everyone's ok) that involved and destroyed my laptop's power cord and as part of that fun I seem to have had a power surge that has reset some of the defaults on my computer but not all. Some of the folders I created prior to the surge are gone, etc. The only real problem is that the permissions on my internal hard drive seem to have been reset. Below are the things it will and will not allow me to do.
-- I cannot copy files from a flash drive, cd or external hard drive to the internal hard drive. I get that circle with a line through it. Clicking and dragging, copy/paste, nothing works.
-- I can move stuff that is already on the internal hard drive from folder to folder.
-- I can save email attachments to the internal hard drive.
-- I can copy stuff from internal the hard drive to a flash drive, cd or external hard drive.
-- I can read the files on flash drives, cds or external hard drives, such as a movie file, just fine, they run without a glitch. The peripherals did not suffer any resets as a result of the fire/power surge. When it happened the computer shut down automatically and I think that saved the accessories from being damaged because the computer is the only thing that showed any changes after it happened.
And before someone asks, yes, I checked, I have 40 GB of HD space so it's not a space issue.
I right clicked on MAC HD and did the Get Info and looked at the details of the permissions on various files and tried shifting some of those around but even though it says Read and Write it still won't let me copy to the internal drive from other sources. Interestingly when I got to the User file it was marked Read Only but changing it to Read Write didn't help. Something I did once worked but then it stopped working so I have no idea what it was. I put everything back the way it was. Could somebody please help me? My computer is old and dieing a slow painful death but if I can make it last a little longer that will make my life so much easier. Please let me know if you need any system info or anything.
*Thank you!!*
PS. I'm not posting this on the peripheral thread because the problem isn't really the peripherals, it's the system not wanting to play nice with others, so that's why I put this over here.

Hi. It's not a dumb question, cause if it is then my answer is really stupid, what's a repair permission? lol I don't know what that is so I guess the answer is no, though I can guess from the name it's a program to fix permissions if the files get messed up? I knew how to change the permissions in Get Info but past that I was getting into things I don't know so I figured it was time to ask for help or I'd be on here asking how to un-erase a hard drive. jk So how would I do that and is there anything else I should do?
Sorry if my initial post was a bit defensive. I had a moderator give me flak over some minor thing on a post once and I was supremely frustrated with this problem. Sorry if it came out kinda angry. I appreciate any help you can give me.

File recovery after system recovery?

One of our students has a laptop that has had a system recovery performed on it by someone else by holding the zero key while pressing the power button. I'm trying to see if any file recovery is possible using standard forensic tools or suites. I haven't been able to find out exactly how the system recovery process works so I don't know what I have to work with. Does anyone know how the original partition is cleaned up before copying the files from the hidden backups?
Thanks in advance for any help or information you can offer.

I have windows 7, had a power surge that shut down my desktop pc, restored to a prev date, firefox was installed then, now I can't uninstall it. How do I uninstall it now?

Hi I tried firefox as a browser but didn't keep it. Uninstalled it and put explorer 9 back on. Tonight a power surge knocked out my desktop pc totally. When I got it back on, there were start up problems. Start up repair restored to a different date, and it happened to be the date when I installed firefox. I activated explorer 9 again, then tried to uninstall firefox, but the uninstall won't work from the control panel. How do I uninstall firefox now?

If the Control Panel method doesn't work ([https://support.mozilla.com/en-US/kb/Uninstalling%20Firefox Uninstalling Firefox | How to | Firefox Help]), try the program '''helper.exe''' in this folder:

Post-power surge question. Please help.

I just had a power surge and my G5 iMac shut off. However, my external hard drive did not. I restarted my computer and the external hard drive is not appearing on the desktop. I don't know what to do. Should I simply shut off the external hard drive and restart it? I would really like not to tank the external hard drive. We're supposed to getting high winds tonight from Hurricane Earl, so I need to get this straightened out rather quickly so I can shut everything down properly.
I will appreciate any help or suggestions.

It's likely that the external drive isn't 'mounted' and also possible that any firmware in the drive (depending on the model) may be wedged. A simple restart (power off, then back on) will probably solve the problem. If you're worried the Mac really did mount the drive but just isn't showing it on the desktop, you can check.
Open "Disk Utility" -- it's in the Applications -> Utilities folder. The left margin of Disk Utility will show all local drives and filesystems visible to the Mac whether the filesystems are actively mounted or not.
If the external drive does not show up in Disk Utility's list, then the filesystem isn't mounted. Power off the drive. Wait several seconds to allow it to spin down. Then power it back up. It should appear on the Mac after a short delay.
If the external drive is formatted with an HFS+ "Journaled" filesystem, your drive should be fine (no corruption) even though it suddenly lost power. If it happened to be in the process of performing a 'write' (e.g. saving a file) then that file may be incomplete, but the drive & filesystem itself should be fine.

Intel-based Macs: Resetting the System Management Controller (SMC)
More likely you will need to reinstall OS X:
Reinstalling OS X Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Reinstalling OS X Without Erasing the Drive
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility and press the Continue button. After Disk Utility loads select the Macintosh HD entry from the the left side list. Click on the First Aid tab, then click on the Repair Disk button. If Disk Utility 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 Disk Utility and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
Alternatively, see:

OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X

Help! - Power surge during capture.......media management question

Hi all.....a power surge occured just at the end of capturing a 40 minute tape, and the computer shut off (I will be hooking up my battery backup immediately!).......I believe the media still exists on the capture scratch disk, but no clip appears in the browser. If the media exists, is there a way in FCP to create a clip to link it to......or do I just have to delete it and re-capture??
thanks for any advice & info!!

You could always check the actual file (if there is one) in the folder you designated in FCP as the "Capture/Scratch folder. If it plays fine in QT Player, it may be alright ... but my advice would be to recapture.

30GB Power Surge

I plugged my 30 GB Ipod into an Internet Cafe computer here in Bangkok. I felt a power surge which isnt unusual here and I looked at the screen and saw that it had turned completely blank. There was no "Do Not Disconnect" sign as per usual. I took it back to my apartment and plugged it into the charger, thinking that this may do something to restore power to my Ipod.
Well the power came back on but the power meter will now only show a Completely charged icon until the battery dies. Then when I charge it it shows the usual lightning bolt.
In addition the Ipod cannot connect to my laptop, any other computer, even with a different USB cable. I havent tried updating it as it wont be recognized by a computer whatsoever.
Im not really sure how to go about completely resetting it as Im somewhat confused as to how to backup files when I cant make the drive readable.
Since the power surge the player has worked, playing songs and in fact updated my artist list to show every artist that is actually on the Ipod. (Before the songs were there but some artists were missing...seems to be a common issue)
Battery life seems normal since.
Prior, I had a complete erase of my hard drive about a week after I bought the ipod. I blame that more on myself (disconnected incorrectly possibly)
I have about a month left of warranty protection so Im wondering what steps I should take?
Thanks,
Mike

Can I use gpt to recreate/unerase a partition table? (Rebuild the GPT/GUID partition table?) I don't want to do FILE recovery.

(Yes, I've googled a bunch and read threads like this one already.)
Can I use gpt or some other app to recreate/unerase a partition table? That is, how can I rebuild a disk's GPT/GUID partition table?) I don't want to do FILE recovery.
What happened: Instead of erasing a single partition off a disk with many partitions, the entire partition table was erased (using Disk Utility, w/o deleting the underlying files). Somehow the "Erasing a disk deletes all data on all its partitions." warning message was missed.
I have a copy of the output of df, with the number of blocks in each partition, from just prior to the erasure, so I should be able to recreate the GPT/GUID partition table. Editing the GPT with a hex editor is not feasible. Simply recreating the partitions with Disk Utility will overwrite the key filesystem tables on each partition, and I don't want to do that, plus Disk Utility doesn't allow me to specify exact partition sizes anyway.
Surely there's an app for rebuilding the partition table (other than emacs' hexl-mode!) for recreating/unerasing a partition table when the partition sizes and orders are known? I've looked at the advertising for a bunch of recovery software and none of them clearly indicate that they will do what I want.
I guess I can try using gpt on a copy of the reformatted drive I've made with dd, and see what happens. But perhaps someone knows of a tool that should do what I need, or knows if gpt is that tool or not.
There are answers and tools that will do FILE recovery - search for files and recover the ones that aren't fragmented or deleted. As far as I can find, they just look for files on the disk, and don't pay much, if any attention to the filesystem info or directory heirarchy, which in this case is valuable. Of course I could send it in to DriveSavers, or the like. But none of that seems necessary, and the scavenging file recovery apps won't do the job well,
E.g. some are mentioned here:
I don't want to do FILE recovery.
Thanks for any help.

Aperture has the ability to work with files in their existing location. They are called "referenced masters." When you import images, you should select the "In their current location" in the "Store Files:" drop down box. Have a read of the documentation for full specifics. Unsure how you can resolve your duplication; might be some work but next time have a read of the manual first
Information for versions is stored in the Aperture database (library file). The masters can be inside the library file itself, or they can be somewhere else.

Shuffle power surge ?

I bought a shuffle to mess around with,after leaving it to charge for 4 hours, it is not recognized by my PC, and I am getting the message 'power surge on hub port - A USB device has exceeded the power limits of its port hub, click to reset' Net result is the ipod is not recognized either by my PC or itunes anyone seen this one before, and is there anything I can do?
Thanks

IPOD Shuffle not recognized by computer, and caused a USB power surge

Device is not recognized by computer, and I tried the listed support recommendations.
The problem originated when I plugged the IPOD shuffle directly into the computer USB ( not using a hub), and this caused a warning window to appear saying unknown device has caused a power surge to this port, and most be removed. Prior to this event, the IPOD shuffle has worked (with direct contact with computer usb or through a powered highspeed usb hub) without issue for nearly 1 year. Any taker's on this issue? Thanks.

Hi JBR,
Go to your control panel and click on Install/Uninstall programs. Scroll down and see if you have multiple versions of the ipod updater installed on your computer. If you do, then uninstall both versions. Reboot your computer.
Next, go to the downloads page and download/install the 1-10-2006 ipod updater. Once installed, go to your start programs and select ipod updater from there. Plug in your ipod and wait a moment. If it's like mine, it'll recognize your ipod and then you can do a "restore" for a clean format.
After that, open itunes and life should be good.
Hope this helps!
