Drive suddenly stopped working

Hi there, can anyone help/advice on this issue. My Lacie external firewire drive suddenly stopped working, the green light on the power pack had died so i replaced the powerpack thinking this was the problem. Still nothing. Te HD does not show up on the desktop or disk utility. The drive does not seem to power up audibly like before, although the blue light comes on. I have tried it on several other newer more powerful macs in the office and still no joy. Ideas? thanks

hi there, thanks for getting back in touch. Yes I guess it could have just died The power brick is rated the same yes, same input power and output, also tested on another brick which belongs to another drive exactly the same. I dont think there is any warranty, it is about 5years old. Not tried the USB, I will give it a try though. Not sure what the drive configuation is inside the case, but may try and remove them and put them in another case, see if I can get any data off. Thanks

Booting my imac from an external firewire drive suddenly stopped working. Disk still mounts but it will not boot the machine!

I took my MacBook Pro in for repairs and erased the drive for safety AFTER having copied the entire contents to an external firewire 800 drive using SuperDuper!
The copy process made the disk bootable and I was able to boot up my iMac and run it just as if I were working on my MacBook Pro. After a couple of times working this way, the iMac stopped booting from my drive.
The drive shows up when starting up by pressing the option key but then, after a long time, the iMac shows a circle/slash symbol as if it can't find the system files.
If I restart without pressing the option key, the disk mounts on the desktop and I can use it as an external drive just fine! I tried selecting it in System Preferences as the startup disk, but the same thing happens, blank grey screen with the circle/slash.
Since this happened with a Seagat drive - a brand that has failed me in the past many times - I thought it was a disk problem. I had backed up my MacBook pro contents to another Toshiba drive, and booted from there perfectly well for a couple of times...
Until the same thing happened! Thank God I didn't trash the Seagate although it makes very faint clicking noises that will keep me far away from using it again anyway... but that's another story!
iMac runs 10.5.8, the boot disk (and my MacBook) runs on 10.6.8 if that makes any difference... And now I'm scared that when I copy back to my MacBook Pro it might not boot up at all!!!
What gives???

You need to reinstall Snow Leopard onto the external drive:
Reinstall OS X without erasing the drive
Do the following:
1. Repair the Hard Drive and Permissions
Boot from your Snow 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.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.

My flash drive suddenly stopped working.

I was transferring files from a Geek Squad 16GB flash drive when I got a error saying a file couldn't be read, then another error saying the drive had been improperly ejected, and the drive disappeared and then remounted. I moved a few more files, and I got the same error saying a file couldn't be read, then the same one saying the drive was improperly ejected, and the drive vanished.
Now the drive no longer shows up in Disk Utility, but it does show up on a System Report. It does not show up on my other computers—either my Mac Mini or a Windows 7 laptop.
However, if I leave the drive in the port, my Air will periodically try to re-mount it. The light on the drive will flash, and an error comes up that the drive is unreadable, and I am given the option to Initiate, Ignore, or Eject. If I go into Disk Utility before I make a selection, the drive is visible, but not selectable.
I have tried all three options with no success. I have restarted, rebooted, and rest the PRAM.
Nothing works.
I need the files off of the drive, so what should be my next step?

I would try all USB ports and if no change, on another Mac. If no success, the USB drive is corrupted.
Ciao.

My Western Digital external hard drive suddenly stopped showing up on my Macbook Pro and disappeared from Disk Utility. It works on a PC.

My Western Digital external hard drive suddenly stopped showing up on my macbook pro and it disappeared from disk utility. I have tried making invisible files visible but nothing has worked and my hard drive shows up on a PC but not my Mac anymore.

What is the manufacturer of the external and how old is it? Does it have its own AC power supply or is it USB bus powered?

I just brought my MacPro in for service and they replaced my hard drive. However, now my disc drive has suddenly stopped working! Is there anything I can do to fix this without having to take it back in for service, again!?

The nearest service center is 2 hours from my house and my computer isn't under warranty anymore, so I need alternative options. I'm just frustrated that my disc drive was totally fine until AFTER I took it in for service. I just paid a lot of money for a new hard drive from the apple store and now my disc drive has suddenly stopped working correctly. I tried with multiple CD's and DVD's...loading a disc, but my computer would just make a weird loading noise and then eject the discs. Now it has started fighting taking the disc, so I have stopped trying. Is there anyway to fix this problem without taking it in for service again and paying another boat load of money?
Thanks in advance for your help!

ShelbyMackenzieLynne,
when you say that your disc drive is damaged, do you mean your MacBook Pro’s hard disk drive, or do you mean its SuperDrive (the CD/DVD drive)?
When you’d updated your MacBook Pro to Mavericks, did the installation succeed, and subsequently freeze up? Or did it freeze up during the Mavericks installation?
Which version of OS X was installed on your MacBook Pro before you’d installed Mavericks?
Are you currently able to boot into the Mavericks recovery partition? To see if you can do so, hold down a Command key and the R key while starting up your MacBook Pro.

My usb that i have been using on my computer for a while suddenly stopped working, but is still glowing and letting me know that it is connected, but not showing up in disk utility

my usb that i have been using on my computer for a while suddenly stopped working, but is still glowing and letting me know that it is connected, but not showing up in disk utility

Either the physical drive or the enclosure electronics has failed. The light you are seeing is powered by the USB connection, the power, electricity, all USB ports put out. That doesn't mean the actual physical hard drive or the USB to SATA bus electronics are working properly. If it doesn't show in Disk Utility then it is DEAD.
Most of the time it is the enclosures electronics that fail. Removing the physical drive from the enclosure and put it in another enclosure or using a SATA to USB adapter, one that has it's own AC power supply, might allow you to get the files off the drive.

Satellite A60-652: ati2dvag driver has stopped working

Hello,
Recently I have some problems with my graphics. My satellite freezes up, and goes to a low resolution with a few colours. A message says the ati2dvag driver has stopped working. After rebooting the satellite shows a blue screen and reboots...same thing happens. Only shutting down and retrying after a few minutes gets me back to normal Windows.
I tried to look for some new drivers, but I can't indicate my model (SA60-652)... is this model too old for updates???
Toshiba SA60-652
ATI MOBILITY RADION 7000 IGP
ati2dvag driver (6.14.10.6430)
Windows XP (SP2)
AVG virus scan
Hitman Pro anti-spyware
ATI hydravision installed but never used :-/
Notebook recently has been rising in temperature...I will deal with this after my final thesis (8 may)
Please can you help me?
If you can, please be clear in instructions, 'caus I don't know a lot about computers... (PEBCAC)
Thanks!

Thank you for this answer,
I found the driver myself, uninstalled the old one and installed the new one (same driver, so actually just a reinstallation).
I use the programm Speedfan to monitor my cpu-temp, and I noticed a few months ago that temperature stayed between 60 and 70 degrees. Now my laptop is easily rising to temperatures of about 87 degrees. Think this is the answer... The notebook even completely stopped working suddenly a few weeks ago, due to high temp. I will look into it to clean the fans and stuff. Guess I'll find some more info on that on other forumthreads.
Thank you for your help

Satellite L300 - Built In webcam suddenly stopped working

Hello,
I have a Toshiba Satellite L300 with a built in 2.0 USB camera and a windows 7 operating system, the camera suddenly stopped working since about 2-3 weeks ago with unknown reason!
I already tried system restore, un-installing and re-installing the camera driver, preformed a full scan by kaspersky internet antivirus 2012 (up to date), and I also ran a complete system and drivers troubleshooting ... and the problem still exists ...
When I use the windows live movie maker it gives me an error saying: cant record audio or video from the selected device. Make sure that the device you're trying to use is installed properly and not currently in use by another program.
The microphone works well on skype but the camera doesn't open!
Please tell me how to fix it, what am I missing?

> webcam appears in the device manager
Is it marked with an yellow exclamation mark?
Usually if the webcam software has been installed, you should be able to start this software going to:
All Programs -> Toshiba
There you should find the webcam software check if you can use and control the webcam after this software has been started normally the webcam control bar should pop up if you would move the mouse cursor above the upper display area PS: the bar can be moved to other area too; left right or bottom

Speakers suddenly stopped working

my sounds suddenly stopped working. After talking to a couple of knowledgeable people, I uninstalled the Realteck audio driver, and then I had decent sound coming through the speakers ! This is for an HP desktop, a6750y
So then I tried to re-install the driver. Although the driver had the same file name, it was newer than the one previously on the system, so I re-installed it, and once again, no sound. So I uninstalled this version, but now I have no sound !!!!
I do get sound through the headphones.
here's what I installed, but it's not working.
This question was solved.

Sound suddenly stopped working.

Hi, my sound on my HP ENVY 15 Notebook PC just suddenly stopped working the other day. Everything says that it is functioning, and my drivers are up to date, but I cannot seem to get the sound to work out of my speakers or out of headphones.
Product Number: A9P60UA#ABA
Running Windows 7 Home Premium 64-bit
If you could help, that would be wonderful! Thanks!

Hi,
Try the following.
Download the IDT Audio installer on the link below and save it to your Downloads folder.
http://ftp.hp.com/pub/softpaq/sp56501-57000/sp56900.exe
When done, open windows Control Panel, open Device Manager and open up Sound, Video and Game Controllers. Right click the IDT device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow this and then proceed with the uninstall.
When complete,download and reinstall the Chipset driver on the link below.
Chipset Driver - Windows 7.
When this has completed, shut down the notebook, unplug the AC Adapter and then hold down the Power and Beats buttons for 10 seconds. When done, reconnect the AC Adapter.
Tap away at the esc key as you start the notebook to launch the Start-up Menu and then select f10 to enter the bios menu. Press f5 to load the defaults ( this is sometimes f9, but the menu at the bottom will show the correct key ), use the arrow keys to select 'Yes' and hit enter. Press f10 to save the setting and again use the arrow keys to select 'Yes' and hit enter.
Let Windows fully load - it will automatically load an audio driver, but just let this complete. Then open your Downloads folder, right click on the IDT installer and select 'Run as Administrator' to start the installation. When this has completed, right click the speaker icon in the Taskbar and select Playback Devices. Left click 'Speakers and Headphones' once to highlight it and then click the Set Default button - check if you now have audio.
Regards,
DP-K

[SOLVED] Thinkpad Fn keys suddenly stopped working

I'm on ThinkPad Edge 14. For some reason(s) unknown, my Fn keys stopped working after I restarted Arch a few hours ago.
I've checked the BIOS, everything is fine (no settings unchanged). I tried checking if X (I'm on Gnome 3) can still detect the keys using xev (as outlined here: https://wiki.archlinux.org/index.php/Ex … oard_Keys) and the Fn key is detected as "XF86WakeUp" witht the keycode "151", so at least nothing is wrong with the actual physical button.
What's more weird is that, I tried booting from another Hard Drive into Ubuntu, and the Fn key also didn't work (it has worked fine previously). What could be causing this?
EDIT: Even weirder, Fn keys aren't working in Windows as well (I dual boot). BIOS's still unchanged, and this started happening when I was working with Arch, so I'm quite sure this can be fixed through Arch. Problem is, I don't know where to start. How can Arch affect Ubuntu & Windows when I didn't change BIOS?

I found out the problem!
I tried checking the Lenovo forums about the problem and found this: http://forums.lenovo.com/t5/ThinkPad-Ed … d-p/323077
Apparently, it's possible that the Fn keys suddenly stopped working for no clear reason. In my case, it happened when I was on Arch, so I thought the problem was with Arch. Anyway, I updated the BIOS from Lenovo's site and everything's working fine now.
Thanks!

My camera all of the sudden stopped working. What is going on?

My camera all of the sudden stopped working. What is going on?

if by camera you are referring to iSight, here is how to troubleshoot:
Built-in iSight cameras
These steps are for iSight cameras that are built into a computer, such as the iMac G5 (iSight) or later, the MacBook, or MacBook Pro.
See if the issue is application-specific.
Try another application (iSight works with applications like iChat, PhotoBooth, and iMovie HD 6) to see if the iSight camera exhibits the same behavior in all applications. If it only happens in one application, try reinstalling that application.
See if the issue is user-specific.
Test your iSight camera in another user account. If the issue only occurs in one user, the issue would be isolated to user settings.
Find out if the computer recognizes the iSight
Check System Profiler (in the Utilities folder, inside the Applications folder). Under the USB header, check to see if the iSight camera is detected.
Reset SMC or PMU
Reset your computer's SMC or PMU, and then check System Profiler again. (SMC reset instructions for iMac G5 (iSight), Intel-based iMacs; PMU reset instructions for MacBook and MacBook Pro.)
If your built-in iSight camera is still not behaving correctly after trying all these steps, you may need to contact Apple or an Apple-Authorized Service Provider for service.
Standalone iSight cameras
The instructions in this section apply if you have an iSight camera that is not built into your computer but attaches to the computer via a FireWire cable.
Make sure the cable is completely plugged in.
Incomplete cable connections are the most common cause of hardware problems. Follow these quick instructions to make sure your iSight cable is completely plugged in.If your iSight camera continues to function improperly, continue on to the steps below.
Turn the computer and the camera off.
Unplug the FireWire cable from your computer and the camera.
Wait a few seconds.
Firmly, without forcing, plug the cable back in to the camera and the computer.
Caution: FireWire ports are keyed so the FireWire cable can only be inserted one way. Make sure you are inserting the FireWire cable into the FireWire port in the correct orientation.
Restart your computer.
If the green light on top of the iSight is not lit, turn on the camera by gently twisting the lens.
Launch iChat AV.
See if a different FireWire port works.
Some Macs have more than one FireWire port. If your computer has another FireWire port, disconnect the iSight camera from the current port and plug it into the other one. Restart your computer and test the camera before continuing to step three.
Check to see if other FireWire devices work.
If you have another FireWire device, such as a video camera or an external hard drive, try plugging it into your computer to see if it works. If your other FireWire devices work, this means that your computer's FireWire port is working correctly. If your other FireWire devices don't work, there may be an issue with your computer. Contact an Apple Authorized Service Provider for assistance.
Determine if there is an incompatibility with another FireWire device.
If more than one FireWire device is connected to your computer, there may be an incompatibility between two of the devices. To rule this out, disconnect all other FireWire devices from the computer, including external hard drives, CD/DVD drives, other cameras, and FireWire-based networking equipment, such as hubs and repeaters. If your iSight camera works normally when you remove other FireWire devices, plug them back in one at a time to isolate the cause of the issue.
Make sure the FireWire cable is good.
Follow these steps to test the FireWire cable:Information about your iSight camera should appear in the FireWire Information field. If you see the iSight camera in this field, your cable is good. Once you've confirmed the cable you are using is good, use it to plug your iSight into your computer. If the green light on the top of the camera does not light up immediately (within a second), there may be an issue with your camera. Fill out an iSight Service Request to have your camera repaired.
Important: Do not send your iSight camera for repair until you have tried each troubleshooting step.If the FireWire cable that came with your iSight camera didn't work, try another FireWire cable that you know works. If this cable works, there is an issue with your iSight's FireWire cable. If your camera is in the limited warranty period, fill out an iSight Service Request to receive a replacement cable.
Choose About This Mac from the Apple menu.
Click More Info. System Profiler opens.
In the System Profiler window, click on the Devices and Volumes option.
Click the disclosure triangle, if necessary, in the FireWire Information area.
Check to see if there is an issue with your camera.
If information about your iSight appears in System Profiler but the camera still does not work, follow these steps:Video from your iSight camera should appear on screen. If the screen is blue or black, there may be an issue with the camera. Fill out an iSight Service Request to have your camera repaired.
Open iChat AV.
Choose Preferences from the iChat menu.
Click the Video button.
Twist the front of the iSight camera lens to open the iris barrier. The green light on the camera turns on when the iris barrier is open.

My bluetooth suddenly stopped working soon after I upgraded to OS 10.9.4. I rebooted SMC, didn't work. Any other ideas? Don't know if it's related to the upgrade. I see other complaints about bluetooth in the thread but none of the solutions offered there have worked for me.

Make a "Genius" appointment at an Apple Store, or go to another authorized service provider. You may have to leave the machine there for several days.

My laptop suddenly stopped working

my laptop suddenly stopped working and when i restart it the power button lights up but the screen doesn't on. and also the capslock is on and another light ons on the keybord with a symbol of all four arrow keys(its not a key) i really am having trouble with it. if anybody can help me please..

Unplug the AC adaptor, remove the battery, press and hold the power on button for a minimum of 30 seconds, then replace the battery and see if it powers up. If not, repeat the above but this time only plug the AC adaptor in and see if it works. If that doesn't help, repeat the above and this replace the battery and plug the AC back in. If that doesn't take care of it you should remove the memory sticks reseat them, them try again. If you have two sticks try with only one at a time to see if that helps. If not, try removing the hard drive and boot to a Linux Live CD or some self booting diagnostic cd to see if the hard drive is the problem. If none of the above helps you'll need to take it to an authorized service center if it's still under warranty, or to any repair shop if it isn't.
