HT201475 Problem with gray screen after connecting external drive

I attached a LaCie external drive to back up photos and iTunes on iMac running Mountain Lion OS. I'm trying to resize partitions to back up but after attaching I'm having problems restarting and/or shutting down. I keep getting gray screen And have to shut down to start up. Now my external drive only shows one partition on desk top and I can't access in disk utility at all.

Hi!
We are having the same problem for years now (Forms10g with webutil) and had no solution but disabling the client cache. But this has to be done on the client.
In this Thread webutil&forms11g R2 64bit
a solution from oraclemysupport is mentioned, which can be done on the server:
JRE CRASHES/HANGS THE BROWSER HAVING HYPERTHREADING ENABLED [ID 601534.1]
(Solution 2)
We'l give it a try....

Problem with a Toshiba PX1267E 320 external drive

Hello all
I have a problem with a Toshiba px1267e 320 external drive, when all was ok with it I would switch on and the blue led would come on and change blue /violet as it was found on my laptop, a small vibration could be felt if I handled the case indicating that the d/d motor was on.
On that fateful morning I switched on did an explore in my computer and found no ext drive, checked the drive blue led on touched the case could detect no vibration, unclipped the drive from the case put my ear to it heard faint clicking.
I removed device and connected to caddie, this time I could feel the motor going, connected to laptop, new hardware found did my computer explore and found no drive, checked device manager and found it so I uninstalled and reconnected usb with same result.
I am not sure what do next.
I had a word with computer shop if they could recover a while I wait they said at least a 6 hour job if possible (dont want to leave at shop)
Bought me another western digital same model no and also new power supply to try swapping the electronics board just in case therein lies the fault /or possible us power/s but I am clutching at straws here.
Any of you guys here got anything like this happen ? any suggestions?
I am curious to know what they would try in the shop to recover although he said he couldn't guarantee results.
I would welcome any helpful suggestions (not throw it in the bin)

I think the external HDD is dead
Maybe its a head crash this would explain the faint clicking and other noises
Unfortunately, I such case you can do nothing

Imac freezes with gray screen after mavericks update

I was updating my imac system and it is frozen in a gray screen, like it is restarting.
It's been twenty minutes and it didn't restarted.
What can i do if it don't restart anymore?
All my work data is on that imac.

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 startup failure is to secure the 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 the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
     a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. 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
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up 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.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start 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 the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up 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, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup 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 restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the 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 restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

Problems with iMac G5 and LaCie external drives

I have an early iMac G5 (without iSight), running OS 10.5.2. I've had a 250GB LaCie external hard drive for about a year now, and it worked fine up until a couple weeks ago, when I got this message:
Disk Repair
The disk "External HD" was not repairable by this computer. It is being made available to you with limited functionality. You must back up your data and reformat the disk as soon as possible."
I was unable to save anything to the drive after this, including altering files already on the drive. Long story short, I bought another LaCie drive, because I needed more space anyway. I got the 500 GB model, moved everything onto it, erased the old drive, and then I had two working drives. I've since only been using the new drive, but just a few days later, I got the same message again, and am having the same problem, but this time for the new drive. I'm not a computer-savvy person, so I have no idea what could be causing this. This happened not long after updating to OS 10.5 from 10.4 - I'm not sure if this could be related. Can anyone help?

One thing to look out for is the power source. If you have a huge octopus of power cords plugged into one outlet, the drive may not be getting enough power to operate properly. That would explain why the same thing happened on two separate drives, both recently. You may have added something new to the +power strip+ that is overtaxing the available power draw.
Someone I know had this issue. It never occurred to him or me to consider this possibility. His external drive was regularly getting disk directory errors. I initially thought the drive was going bad, but once we distributed the power cords to two power strips connected to different outlets, the problem did not recur.
Your problem may be something else, but it sounded too familiar to not mention my experience with the power cord octopus monster.

PROBLEM with Importing video to an external drive

I am unable to import video directly onto an external drive. Whilst the ext drive shows up fine in Finder, I do not get this option on the import drop down menu. Yesterday i spent an hour with the Genius guys in the Regent St Apple Store. They both said that they'd done this before, but were both unable to get it to work on their hardware. It appears it should work, but doesn't!! We tested on mac formatted ext drive so it wasn't a pc formatting issue with the drive.
The guys at Apple said maybe it was a problem with a recent update to imovie which to me sound unlikely!
I use the latest version of iMovie 09, Snow Leopard & a Mac book (2yrs old)
Any ideas really appreciated
Thanks in advance

Several things are not officially supported by hardware and software manufacturers, but that does not prevent them from working very effectively. I have used LaCie firewire drives on many occasions on the same firewire bus as my DV source without any difficulty. I think that the settup that you propose will be potentially more problematic than using the same firewire bus. The reasoning for this opinion is that USB does not constant guarenteed bandwidth where firewire does. Theoretically speaking USB sould work under optimal conditions and there are some people using it, however I have heard of far more problems with the USB drives than firewire.
Things to look for in an external firewire drive include an oxford 911 or better bridge board and a drive speed greater than 7200 RPM. I have used 5400 RPM drives without any problems, but others have had problems with these as well.
Canon cameras have several quirks that have proved problematic when trying to integrate them as a source into video production settings. You may want to invest in a stand-alone deck or alternate brand camera to import your footage. This does not mean you can't try to use the Canon as a source. Several people do on a daily basis without difficulty. I would recommend trying what equipment is most easily availablr to you and determining what works best with your configuration.

Problem with time machine after replacing hard drive

A couple of days ago i went to the apple store and got the hard drive replaced on my macbook pro. When i got home i realized i couldnt back up from my time capsule. When i open time machine the only backups i can find are from "today" and i cant find anything else. I have not deleted anything and have not got any warnings about any backups being deleted.
I then went in to the time capsule from the sidebar in finder -> data, in which i found two sparsebundles. When clicking on the one i needed, i got this message:"no mountable filesystems". And from here on i dont know what to do.
I have been reading all over the forum, but can not find the answer. Also have in mind i am NOT a mac geek and know very little about this. I just want my important files back on my mac in a way i can understand.
Any help appreciated!

Install Mavericks, Lion/Mountain Lion Using Internet Recovery
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
This should restore the version of OS X originally pre-installed on the computer.

Macbook Pro late 2013 - problem with login screen resolution

Hi,
I've got problem with login screen resolution, after upgrade to Yosemite. I use the 4rd resolution (last one) on my Mac Pro (late 2013), and after restart login screen is always on optimum mode... But it's only about the login screen.
Do you know how can I fix it? I would like to have the same resolution on every screen.
thx in advance

I Reformatted the CF card on the new computer   it works fine now on the new Mac Pro
Interesting point about the low power of the usb ports   I had to deal with all devices ejecting them selves when the mac pro was idle or slept Drobo needed a Firmware update and another drives needed me to change the sleep setting or the Mac Pro   to never and i also had to deploy a script to write to each device ever minute,   this kind of sold the problem with external Hard drives.   I wonder if the lowering power to a CF card   can eject it in a manor which would make the computer think it is corrupt.
I have looked at buying a power usb Hub    but seems only one or two of the ports are powered.
Seems to be a bit problem with the mac pro especially as everything has to be connected externally
Will assume the Firewire Connector does not work.

Problem with matrix/screen in Qosmio F55-Q502

Hello
For a few weeks I have strange problem with matrix/screen in my laptop.
The matrix flickers very often - no matter if power cable is plugged or not.
The screen is full bright and suddenly it starts to blink - it is getting darker, than lighter, usually for few/dozen seconds. It does it when nobody touches it or when I work on it.
It very annoying and making eyes tired - it does it very quickly and there are few levels of screen brightness.
Moreover sometimes the screen turns off - You can see what is on desktop but the screen is very very dark (but not blank or completely switched off). It happens without any reason - sometimes just in the middle of working, sometime for example when I touch (not pull) the power cable between laptop and power supply.
Then, the only way to get back to normal brightness of screen id to close the lid just for half a second and open it
- matrix lights then normally, but can "turns off" moment later and I must do it once again - sometimes even few times..
After "action" with lid screens seems like nothing ever happen..
Does anyone have idea what is the cause of such behaviour or how to diagnose it in details?
Or maybe solve this problem?
Best regards
300m

Sounds like the Backlight or Inverter is failing or there is a loose connection.
Is the unit under warranty? Send it to an ASP for repair.
You should avoid repairing it yourself, the backlight is very high voltage!

I have an IMac running the latest level of Lion. Since installing Lion and also being forced to replace the hard drive I have a problem with the screen intermittently go all white. Happens about 8 to 12 times a day. I am using Wild Blue as my ISP.

I am looking for anyone in the west Tennessee area using Wild Blue along with Apple IMac who is having a problem with their screen going complelely white every so often. Have had the maching into the Apple store in Memphis. They could not get it to fail. Help

TutorDaddy, if this Mac is still covered by the initial warranty or under AppleCare, take it in and have it looked at. As the old label used to say, there truly are "no user serviceable parts inside." Kernel panics very usually indicate failing hardware.
I have an older iBook G4 that started developing kernel panics and like you, despite reinstalling the OS from a freshly formatted volume, they kept continuing. I looked at the crash log and saw that in each instance of panic, the last bit of code to be accessed had something to do with AirPort. Knowing that the AirPort software was at then current levels, I surmised the problem to be a bad AirPort networking card which, on that particular model of the iBook, was a very small module attached directly to the logic board. Since the computer was out of AppleCare, I broke the machine down myself (I didn't realize that there could be so many barely visible screws in one machine) and removed the offending piece of hardware. My iBook lives but without WiFi, it now sits as a more or less desktop machine needing an ethernet connection to stay connected to a network.
I do not suggest you break into your iMac. First of all, I'm guessing one would need to be able to pull off the glass and have the necessary glue to reattach it, which is not really available to us consumers. If you're feeling adventurous enough to read the crash logs from each panic, you might be able to surmise the hardware component (or badly written application or library; it can happen) that's causing the panic. If it's a software issue, remove the offending software app and see if the panics return. If it's a hardware issue, it's best to let a competent service tech qualified on Apple hardware to handle it.

After browsing through related problems in the discussions, I saw this link to a third-party web site being handed out. Perhaps you'll find it useful: http://www.thexlab.com/faqs/kernelpanics.html

How can I debug a problem with the 3g data connection on my iPhone 4s?

This question didn't get any answers in the "Using iPhone" forum. Thought I would re-ask here. Note, I had to reset the network again today 2 days after the last reset:
I've been having intermittent problems with my 3g data connection on my iPhone 4s on ATT. Whenever this happens I see full bars etc, but can't browse from safari or get any data in other apps. My wife's iPhone 4 right next to me has no issues at all. Switching on/off airplane mode and turning off/on Cellular Data does not help. The only thing that helps is resetting the Network Settings or hard restarting the phone.
I figured my problems were hardware related so I took my phone in for a replacement the other day. Things started out fine but after I upgraded it to 5.01 and restored my backup and now I am back to having the same issue today. I assume the issue is with something coming from my backup / restore but is there any way for me to pinpoint what could be causing the issue. I have a lot of apps, I'd rather not have to reinstall and set them all backup manually, but I would if I knew that would fix the problem... but for all I know one of the apps could be causing it.
Anyone have any logs I can check or testing I can do on my end?
Thanks!

Unfortunately, Apple does not make any logs available to the average schmoe (like us) for networking, kernel dumps, or anything else (assuming, of course, it is not jailbroken).
Your best bet is to take it back into the store. Ask them to look at the notes in GCRM regarding the last time this occured, then explain after upgrading to 5.01 it is occuring again. Then ask them for a phone swap since it is a reoccuring issue and doesn't sound like an OS/SW issue. Good luck!

A lot of users with white screen after lcd replacement!

Hello!
So i have a macbook air with a broken hinge.. replaced the screen assembly as in the guide on ifixit. All ok, but after replacement the screen is white with light vertical stripes. Now i have done some research and found out there are a lot of users with the exact same problem but none with a solution.
I think the reason why the screen turns white (most of the times) is because of the lcd modelnr en most importantly versionNr! The lcd model of the macbook air original is: B133EW03 but there are 4 versions of this screen: 0,1,2 and 3 respectively. In this link (page 3)http://www.ttsystem.ru/data/B133EW03_V1_Others_0204.pdf you see V1 is an upgrade of V0, in the way that the EDID codes have changes and so the OS has to send different codes to the lcd for it to 'understand'. I couldn't find the exact changes in V2 and V3 but i'm guessing it could be similar.
So my question is could this be possible?? is it possible or does anyone know you need the exact same lcd screen (model en version) when you replace your lcd screen?
Another very strange thing is that my macbook air shows some discrepancies:
The bottom case of my macbook air says A1304 and the serialNr off course. But the motherboard shows the A1237 model..Step 14! (In this ifixit guide http://www.ifixit.com/Guide/Installing-MacBook-Air-Models-A1237-and-A1304-Displa y-Assembly/855/1
Also OSX gives me the data:
MacbookAir 1,1
1,8ghz core 2 duo 64gb ssd (which isn't a a1304 model..)
but the same SerialNr!
When i check the specs online using the serialNr i can see it's made in week 50 of 2008.. in my opinion it's impossible it's a a1237, because apple introduced the a1304 in october 2008..

I had the same problem with the LCD after replacing hinges and could not figure this out.
To solve the issue, I bought another A1237 of eBay that apparently had no HD/SSD, but it arrived with a swollen battery. I removed the bad battery and replaced and moved SSD over and "Voila"...it amazingly light up...........
