MBP can't find SSD after kernel panic

I installed a Crucial  M500 240GB SATA 2.5-Inch 7mm drive using an Other World Computing adapter into my MacBook Pro back in October.  It has been working very well until yesterday.  I typically leave my laptop on and just close the case.  When I opened it yesterday, a kernel panic message came up and after a few seconds the machine rebooted to my internal hard drive and I was able to continue working.  The SSD just had my applications and system so my work materials (docs, etc.) are OK.  However, the machine can "see" the SSD drive.  I have tried Disk Utility and Drive Genius with the same result.  Before I start opening the MBP, can anyone suggest other steps to take?  I have the system backed up to Time Machine.

Welcome to Apple Discussions.
Are you able to boot from the install disk or the Apple Hardware Test disk?
If so, boot from the install disk and Repair Disk
Insert Installer disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel, and report if it says anything but Verified)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
If DU reports errors it cannot repair you will need to use a utility like Tech Tool Pro or Disk Warrior
Then boot from the AHT disk and run all tests in a loop by holding down Command + L during the tests.
Good luck.

  • Recovery session canceled due to errors. Can't start DB after kernel panic.

    Hi all,
    I have a cluster Oracle 10 DB that was incorrectly shutdown (node 1 got a kernel panic when I disconnected the cluster interconnect and after a while node 2 also had a panic).
    Now the DB doesn't start and I already tried an endless loop of solutions that don't work and lead me right to the start. I was hoping someone could help me fix this bloody thing please. This DB was running in archive log mode.

    I also saw the "_allow_resetlogs_corruption". But I would like to leave this as last resort.
    Thanks in advance

    Thank you everyone for the advices. I used this tutorial to implement the allow reset logs corruption, but still it didn't allow me to startup the DB normally without errors or recover the datafile 86.

  • MSI Z87-G45 Can't find SSDs after BIOS update v1.9

    So I updated the BIOS to v1.9 using MSI Live Update 6 just cuz I was lazy.
    After reboot my Samsung SSD 840 EVO couldn't be found, didn't show up in BIOS System Information either. My WD HDD was found without problems though.
    I rebooted a few times and eventually the disk was detected, but after rebooting again it didn't show up any more. Turns out it only showed up about 1/10 boots.
    I installed a new Samsung SSD 850 EVO just to test it out, but it wasn't detected either, still only the HDD. Same symptoms, only once in a while were the SSDs ever detected.
    So I eventually downgraded the BIOS (put it on a USB stick this time) to v1.8 and now they are all found 100% of the time.
    Fun times.

    Out of curiosity: did you clear CMOS after flashing BIOS to 1.9?
    And what way did you downgrade? What if you would use this method to install 1.9 again?

  • How do you find out about Kernel panics?

    Can anyone please explain to me how does one find out about Kernel panics, where to look etc? Thanks and regards

    When the operating system kernel, one of the most basic, foundational levels of the Mac OS X operating sytem, detects some kind of exceptional condition or internal corruption or when the hardware sends it a signal of some grave error, which can be a bug in the system software or a driver or can be a hardware problem and the situation is not one that can be dealt with and continuing operation is impossible, then the kernel "panics." It does it's best to shut down gracefully, but it's an abortive termination of all system activity, after which a reboot usually takes place (though you're notified and must intervene before that happens).
    It is a serious error and should not occur, but computer technology, both hardware and software, being what they are, there's no way to absolutely guarantee they won't happen. Unix-based systems such as Mac OS X have pretty good reliability, especially since Apple controls both the hardware and software. Still, 3rd-party software can be incorporated into a system, and Apple does not control or certify that code, so there's ample opportunity for poorly written add-ons (especially hardware drivers) to cause problems.

  • I can't find iSync after lion install

    I can't find iSync after lion install. I try too sync with my N8 Nokia. The program iSync dont appear in program mapp.

    It's Apple's software not yours and as shown by it's exclusion on the OS X Lion pages is not part of the new OS. Upgrading to Lion is optional.
    It's a trivial matter to copy it back from your Snow Leopard backup, but using it under Lion is not supported at all and WILL stop working sooner or later.
    Why would it be sensible for Apple to include software in their new OS that they know will stop working?

  • IPhone 6 screen freezes and can't find wifi after iOS 8.0.2 update

    iPhone 6 screen freezes and can't find wifi after iOS 8.0.2 update. Have to do a hard reboot. I am Extremely disappointed and lost ALL trust in Apples Quality Assurance. From now on I'll wait a week before I update.

    Hey there Shortos,
    It sounds like your phone touchscreen is not consistently working for you after updating to iOS 8. I can see how that would be pretty frustrating. It sounds to me like this could be a software issue or an issue with the screen itself. I would start with the troubleshooting in the following article to help troubleshoot the screen itself:
    iPhone, iPad, iPod touch: Troubleshooting touchscreen response
    Restart your device
    Hold the On/Off button until "slide to power off" appears. Slide to power off your device. When it is off, press the On/Off button to turn it back on.
    If you can't restart your device, reset it by pressing and holding the Sleep/Wake button and the Home button at the same time for a least ten seconds, until the Apple logo appears.
    Clean the screen with a soft, slightly damp, lint-free cloth.
    Avoid using the device while wearing gloves, with wet hands, or immediately after applying hand lotion.
    If you have a protective case, or if you are using a plastic sheet or film on the display, try removing them and testing the device without it.
    If that does not resolve the issue, I would next quit all the running apps on the device:
    iOS: Force an app to close
    Double-click the Home button.
    Swipe left or right until you have located the app you wish to close.
    Swipe the app up to close it.
    When you have done that restart the device and test the issue again:
    iOS: Turning off and on (restarting) and resetting
    Thank you for using Apple Support Communities.
    All the very best,

  • SSD fails to verify after kernel panic?

    I have been using a 256GB Samsung 840 Pro SSD as my main boot drive in my MBP for about 6 months now with no issues. Last week, I randomly got a kernel panic and had to reboot my mac, however, it failed to boot. After opening the recovery tools, the disk utility failed to mount the SSD. After trying to reboot several times, the drive finally mounted and I tried a verify/repair, both of which failed. I also tried the Apple hardware diagnostic tool which ran without issue.
    I then took the drive out and placed it in my Windows desktop. Using Samsung's disk "magician" I ran a diagnostics of the disk which said nothing was wrong. I updated the firmware and tried it in my MBP again where it still failed to mount/verify.  I then put the disk in an external SATA->thunderbolt enclosure I had and the disk was not only recognized but booted, verified, etc completely fine as an external drive.
    I then took my old internal HDD and put that in my MBP, wondering if perhaps it was my macbook that had the issue. However, this also booted and verified fine, suggesting it was in fact the SSD with the issue.
    I called Samsung, and (painlessly) returned the drive and they shipped another one out to me. I continued to use my old HDD in my MBP with no issues while waiting on the shipment. Today it arrived, first I restored my OS to the SSD using my external enclosure and the drive booted and verified fine with no issues. I reinstalled it inside my Macbook and suddenly the drive no longer boots or verifies properly and will not repair - disk utility tells me to format the drive, which I tried, which then produces the same result.
    I then tried resetting the SMC and PRAM, both of which had no effect.
    I am completely at a loss at this point....
    tl;dr Kernel panic, SSD no longer works internally, but is fine in external SATA->thunderbolt enclosure, original HDD boots fine internally. Replacement SSD also fails with same weird issue (works externally but not internally). Regular HDD still works in internal bay.
    After using an SSD for so long I can't go back to just using a regular HDD, the speed difference is painful...but SSD no longer seems to work. What is going on here? Has anyone experienced anything like this before and what are my options?

    The new SSD seems to only have issues verifying partitions. If I select the physical volume in disk utility, it verifies fine with no errors. Any and all Mac partitions (MSDOS seems to work....) fail to verify or repair.
    From what I've found, the only people with similar issues either A) had a "faulty" SATA cable or B) didn't enable TRIM on their SSD. Since a regular HDD still works fine in the internal bay where the SSD was installed, it can't be the former and I had enabled TRIM when I installed the SSD so it shouldn't be the latter.

  • Can't deal with these kernel panics... Should I cave and buy a new SSD?

    Specs: OSX.8.2 / ADATA SX900 256GB SSD / 15in Mid-2010 MBP / No longer under AppleCare
    Problem: Intermittent kernel panics
    What I believe:
    - Source of issue is SSD
         - Took laptop to Apple and 3rd party Apple Certified Specialist, both showed clean ext hardware tests except for SSD, but could not pinpoint issue.
         - Problem travels with drive from body to body.
    - ADATA Firmware/Sandforce SSD does not play with OSX.8.2
         - Kernel panics are not patterned. Never point to specific recurring processes/threads... almost always background/native operations (windowserver, Finder, iTunes, etc). Never during overheating or high graphics/CPU stress. Rarely—but not never—during 3rd party operations.*
    - It is NOT my RAM
         - Reset PRAM, no change.
         - Memtest clean.
    Other things I have done to try to be proactive:
    - Clean re-install of OS.
    - Erased disk, partition. Repaired both before reinstall of OS.
    I am still experiencing the kernel panics and it is making it impossible for me to work. Should I cave and buy an OCZ SSD? Thanks in advance.
    *I am not pretending to be an expert at deciphering panic/thread crash reports, but I believe I have done enough research to get the gist and to have seen a pattern if there were any. If you would like me to post my most recent reports, I would be happy to!

  • Can anyone help with these kernel panics?

    I work for the NHS.  Have spent most of my salary on Adobe Premiere Pro using a Intel Core Mac OS 10.5.8 which is supposed to be enough for the system requirements.  Have spent all day shutting down my computer unable to start the software.  If it does start it freezes and tells me to restart.  This is not acceptable.  Can anyone help??? Adobe cefrtai nly don't want to is there ahtyone out there with any solutions?  I ahve checked the hard drive it is fine, have done all the usual checks to no avail. Cannot find anywhere to talk to Adobe, their website is a minefield of Groundhog Day!
    I have the same problem with Photoshop purchased last year as part of a creative package.  This is really annoying!

    I hope that is more use.  As I said, the software is successfully installed, but I cannot open Premiere Pro.  Photoshop does open occasionally but rather like Russian roulette.
    I also have the Creative suite and Dreamweaver is no problem, neither is Indesign.  This makes no sense to me I would be grateful for any help.  I have checked the hardware and the system is ok.  I have tried re-installing the software after un-installing it but that made no difference.  I obviously have turned the machine on and off because of the black veil that descends upon the screen during the kernel panic.  Premiere Pro has alo frozen everything rather than causing a panic too. HELP!

  • Macbook Pro won't load past white loading screen when turned on after kernel panics

    Hello,
    I have a Macbook Pro and recently its been having repeated kernel panics. In the past few days its been turning off every few minutes or so. yesterday it had one and now when I try to turn it on it doesn't load. I get the white loading screen with the apple logo and a loading bar underneath. But after the bar fills about 5% of the way (if that) the bar just disappears and the spinning loading icon just keeps going without anything happening (however long I leave it).
    Please can someone give me some suggestions to fix this. Just a few things to note:
    a) I'm not great with computers so any fixes please explain in the most simple terms
    b) I have VERY important work files on there that are NOT backed up (big mistake I know), so please only suggest fixes that will not remove these Microsoft Word files. Guaranteeing the safety of my work is paramount with any suggestions.
    c) I may not have any of the disks which came with the Macbook Pro originally (though I may somewhere)
    d) I've read some other forum posts and it seems that I need to know the details of my operating system. I don't know these and have no way of accessing them on the computer (for obvious reasons). Its a late 2011 Macbook Pro if that is of any help.
    A massive thank you to anyone who can suggest a fix to these, I shall be eternally grateful.

    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 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.”
    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. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
    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
    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. The easiest way to deal with the problem is to boot from an external drive, or else to use either of the techniques in Steps 1b and 1c 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 boot 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 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.
    Step 7
    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.
    Boot in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
    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.
    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 corrupt and the drive is probably malfunctioning. In that case, go to Step 6.
    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 8
    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 9
    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.
    Step 10
    Repeat Step 9, 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 Time Machine or other backup.
    Step 11
    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 boot 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 12
    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.

  • MX Revolution USB Receiver can't be removed without Kernel panic

    On my MBP 17", I can not remove the Logitech's MX Revolution USB Receiver without having a Kernel Panic ! I am using the last LCC 2.1 under OS X 10.4.7. I fixed authorizations after the installation. I did test with all three MBP USB ports. I tried without the mouse on and off. It's always the same thing... Grey... Boom... Shutdown.
    I tried the same thing with a MBP 15" running LCC 2.1 under OS X 10.4.7, the Kernel Panic did not show up ! ? !
    Any idea ?
    Cyberlolo

    As an update, I'd like to report a similar behavior on my PowerBook G4 running 10.3.9, with the difference that this does not occur every time. I've had two kernel panics and the only thing in common is that I had turned the mouse off before pulling the USB receiver. The applications mix was different although some applications might have been the same on both occasions. LCC 2.1.1.

  • Mail Reset After Kernel Panic- Accounts/Rules/preferences missing

    My MbP had a kernel panic this evening and after the restart, I opened mail and got the "Welcome to Mail" message.
    Tried restarting again, resetting pram (not sure why, but did), deleting preferences, etc. But all my mail preferences and accounts are missing.
    They do still exist in the ~/library/Mail folder
    But all my rules, smart folders, custom settings, etc are gone.
    Any idea why this would happen?

    Just wanted to make a quick reply because I had the same problem happen today, my MacBook Pro running 10.6.6, crashed with a kernel panic while using mail, although after checking the logs, it appears coreaudio caused the crash (had iTunes open in the background, perhaps a problem there?), had to do a force shutdown and restart (this is a very rare occurance that my MBP crashes).
    When I started up again, mail would not start directly, instead was asking for details to set up a new account with the 'Welcome to Mail' message.
    The fix was to move the mail preferences file (~/library/preferences/com.apple.mail.plist) to the desktop (or trash) and recover the most recent preferences file (com.apple.mail.plist) from time machine or other backup to the original location (~/library/preferences/com.apple.mail.plist).
    Once I did that, restarted mail and all settings, messages, mailboxes, etc.. were exactly in place with no change (even the message I was typing when it crashed was still in the Drafts folder).
    So this fix works as long as you have a back up.
    (note I added extra info/explanation into this post for search engine's sake to make it easier to find)

  • MacBook won't reboot after Kernel Panic!

    Hi everyone! Been reading these boards for a while and it turns out now I need help.
    I was simply browsing the internet (Safari 3) earlier when my one year old MacBook suddenly stopped working with a Kernel Panic. At the time of the crash I had my external USB drive and a USB-MIDI interface connected, both of which have never caused me any problems whatsoever.
    I switched off my external HD and restarted my Mac, thinking this was just an exceptional error. Unfortunately, upon restart, my MacBook gave me the following error message:
    panic(cpu 0 caller 0x003ABD33): Unable to find driver for this platform 'ACPI'.
    And then went into Kernel Panic
    I then decided to try and boot off my OSX startup disk. Thing is, I can't even get to this screen anymore. Subsequent restarts result in a black screen and the sleep light being lit, but nothing else seems to be working. The disk drive makes a short 'eject' noise which is usually followed by the boot sequence but it's as though the whole machine just freezes after making the sound. Sometimes it will go into some sort of loop and repeat the eject noise until I kill the power.
    My MacBook (white) is just 13 months old (out of warranty), 2.16 Ghz C2D, 2 GB RAM. Running OSX 10.4.11 with all updates. Never had a problem with it until today. It's been looked after well and has had regular disk checks, permission repairs and running of maintenance scripts.
    Any help would be most appreciated.

    I have already tried unplugging everything, the problem is that I cannot even get to the startup process. The screen doesn't even turn gray, so I can't even boot up in safe mode.
