MBP mid-2009 Freezing after Hard Drive upgrade -HELP!

So, my Apple Care just ended and I was almost always at a full 320GB, so I decided to upgrade my hard drive to 1TB.  I purchased a Western Digital TB drive (9.5mm) at a store recommended by an Apple Genius and followed the instruction on youtube exactly, as well as having another visit to the Genius bar, ensuring I grounded myself often throughout the process. My computer is a 15" MBP originally loaded with Snow Leopard, now running OSX Lion.  I did a Time Machine backup prior to everything and also bought an enclosure for my old hard disk to use and it has yet to be wiped, but Disk Utility says that it's corrupt because 1 program's debug log says the number of files changed (after the time machine processing.) I did a Carbon Copy Clone prior to installing the hard drive as well, so when all was done, I was able to start the computer without issue.  (This program is what told me first that I had an issue with that debug log.  I'd tried to delete a huge folder that was taking up nearly 30GB before the clone, it was backed up on time machine and another backup drive.)
However, after Vuze re-opened (which I'd just recently upgraded to Pro) it froze the computer, so I got the rainbow disk and even Force Quit did not work.  Since then, I've had to reboot with the top right button dozens of times.  Mail, Chrome and Vuze have all caused freezing and Command Option Escape does not work at all.  My beloved computer is starting to feel like a big brick.  I uninstalled and re-installed Vuze Plus since, but still have the same issues (trashing the program then re-downloading).  As for Disk Utility, it says the drive is just fine.  There are no software updates needed and that's about as far as I can get before things crash again.
I would really appreciate any assistance that can be provided based on this scenario.  I hope I've provided enough detail, please let me know if more is needed.
Thank you in advance. 

The only thing that I can think of is that your SATA cable may be bad... it's the first thing that I would try replacing. DIsk Utility wouldn't be able to detect a bad SATA cable - you'd just have random freezes and crashes.
I don't know that this is the solution to your problem, but it's the first thing I would attempt. 2009 models are notorious for having bad SATA cables - try PowerbookMedic and order a new one. If it doesn't fix the problem, call back.
Good luck,
Clinton

  • How do I reinstall my operating system after hard drive upgrade on MacBook pro?  I have Snow Leopard install disc

    How do I reinstall my operating system (Snow Leopard) after a hard drive upgrade. I did a Time Machine backup before the new hard drive was installed. I put in the Snow Leopard install disc and don't get the icon I'm supposed to double click to install Snow Leopard and then the backup.
    HELP PLEASE!!

    Is the new HHD in the MBP?
    Is the new HDD formatted Mac OS Extended (Journaled)?
    Where is the old HDD? In an enclosure?  What is on the old HDD, your user data?  Is the Snow Leopard System on it?
    Do you have a separate Time Machine Disk with your user data?
    Answers to these questions should give an exact status of your situation so that one can proceed in the right direction.

  • Spinning beach ball after hard drive upgrade

    Im running a macbook pro i7 2.2ghz  8gb ram  version 10.6.8 SL
    I recently upgraded my 128gb ssd to a 512gb ssd drive.  I cloned the drive to new drive and ever since then, I get the spinning beach ball very often whereas I never got it prior to the hard drive upgrade.  Is there anything I can check or do to eliminate the freeze ups?  It is VERY annoying.  Or do I just need to do a fresh install on the new hard drive.
    thanks in advance

    Did you properly prep the drive first:
    Drive Preparation
    1.  Boot from your OS X 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.
    If you are preparing an external or a non-startup drive, then open Disk Utility in your Utilities folder.
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
    4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
    6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.

  • IPod sync problems after hard-drive upgrade/change

    Hello all,
    Can anyone PLEASE help?
    I have just had my hard drive upgraded/changed from the original 640GB drive to a new 2TB drive. I've also had an additional 4GB of RAM added to now give me 8GB RAM.
    Absolutely everything else seems to be working fine (unusual for me and I'm often at the end of bad luck in such circumstances). The only thing I'm having problems with is syncing my iPod Classic with iTunes. Incidentally, I have the latest version of iTunes and my iPod software was up to date  the last time I checked.
    Before I go further, my system specs are:
    iMac
    24-inch, Early 2009
    Processor  2.66 GHz Intel Core 2 Duo
    Memory  8 GB 1067 MHz DDR3
    Graphics  NVIDIA GeForce 9400 256 MB
    Software  OS X Mountain Lion 10.8.2 (12C60)
    When  I connect my iPod Classic, the iPod screen initially shows  'Synchronisation in progress' (or whetver similar wording it actually  is)... but this is just very briefly. It then indicates "Connected", and  that's the way it stays and doesn't change at all.
    It takes time to actually show up in iTunes, and when it does, I now have to very quickly click the iPod button (to bring up the iPod screen on iTunes) before the pointer turns into the spinning beach ball.
    Now, it hangs... and hangs... and hangs... and hangs.
    During this, I notice that "Manually manage music and videos" is ticked (which I didn't have ticked before), and also 'Enable disc use' is also ticked, although greyed out.
    Occasionally, the spinning beach ball will disappear and the pointer will return, but this is very very briefly and I have a split-second to try unticking - first - the "Manually manage music and videos" box and then - later, if I'm lucky - untick the 'Enable disc use' box. However, on the odd occasion I've managed this, I haven't been able to go further except for two occasions when I managed to click "Apply". The iPoid on those to occasions started to update... but went nowhere... it just did nothing.
    When the thing finally just hangs and hangs, I eventually have to 'force quit' iTunes and unplug the iPod without first ejecting. There was one other occasion when I managed to - split-second when the spinning beach ball disappeared - to click "eject" and the iPod succesfully did so.
    There were a couple of occasions in the past when I had trouble with my iPhone and was told to delete/trash the iPhone photo cache folder. Remembering this, I tried this for the iPod (iPod photo cache) and it made no difference... same situation.
    I did notice on one occasion at the beginning of all this that when I managed to unplug my iPod from iTunes, all the album covers were missing from the iPod (although still in iTunes). This was long before I tried deleting the iPod photo cache folder though.
    Any help would be greatly appreciated.
    Best regards
    BionicDan

    First things first the spinning beach ball is usually an indication that Search is going nuts.
    Turn off Search entire Library by clicking on the downward pointing arrow to the right of the Magnisying glass and untick Search entire library.
    Is your music still in iTunes on your new hard drive or is it only on your ipod?
    If it is in your itunes then you should be able to plug in the iPod and uncheck Manually Manage music and sync
    If the music is only on the ipod connect up as above click on the device and Drag all the music from your device to the library. then you can uncheck manually manage music and sync as normal

  • MBP (mid-2009) freezing, slow installations and file transfer

    I bought the latest MacBook Pro model and installed Snow Leopard on a cleanly formatted hard drive. I have tried migrating via ethernet and FireWire from my iMac, but the migrations failed either due to freezing (via FireWire after roughly 24 hours of file transfer) or by an error message (ethernet with Migration Assistant).
    Only through a Time Machine backup was I able to transfer my account files to the MBP, which again totaled at over 20 hours of transferring. The system was a mess, clogged constantly by freezing and spinning beach balls of death for durations lasting around 10-20 seconds during which music would clip after 5-10 seconds of everything not responding, this being accentuated especially during installations. I decided to format and try anew.
    Now I've formatted the hard drive, installed Snow Leopard and will transfer my files manually onto a clean account. Installations take a long time although SL installation is within 30 minutes, iLife took 1.5 hours to install 5 GB. During the installation Safari stopped responding, as did the entire system, and the spinning beach ball would keep spinning. Watching a 480p trailer in Quicktime made the entire computer freeze up (no video/audio) for 10 seconds halfway. Transferring 136 GB (my Music folder) will take around 15 hours according to the estimate after 10 minutes of transferring.
    I've sold my iMac now and all I have are the files on my external hard drive. I want to get them onto my MBP ASAP but the slowness is preventing me from doing what needs to be done and it's very frustrating. When I try to boot into Hardware Testing by holding D down the computer doesn't do it no matter what (Application DVD in or not, plugged into power or not). I've tried resetting PRAM but I get the same inaction.
    Any ideas?
    Edit: I've done Disk Utility to no avail, it finds nothing wrong.

    Installed, still getting freezes with spinning beach balls. Transfer says it would take 1 hour opposed to that 15 hours, but it stops transferring after X amount of gigabytes (from 0.5 to 5), not do anything for a while and then continue, stretching the estimate to over 2 hours after some time. I don't know if this is just with the hard drive.
    The freeze-ups are frustrating as **** and make for a very poor experience. Any ideas to get to the bottom of this? I still haven't been able to boot into the Hardware Test no matter how much I try.

  • MacBook Pro (13-inch, Mid 2009) - Maximum internal hard drive size and speed?

    What is the maximum size of hard drive and speed for an internal hard drive to my Macbook Pro (13 inch, Mid 2009), please?
    I bought myself a Technics 1TB, 7200 rpm internal hardrive. Made a clone successfully in Super Duper.
    It fits, but It is not available for starting up my Macbook Pro. Not available in System Prefs, but visible and grey in Disc Utility.
    Although it starts up my Mac Pro just fine.. but not my Macbook Pro.
    Is there a limit of hard drive specifics?

  • MAC OS 10.4 CRASHES AFTER HARD DRIVE UPGRADE

    I just bought a HITACHI hard drive for my iBook G4 1.33ghz. I installed the hard drive with no problems. After installing MAC OS X 10.4.2 & upgrading to 10.4.11, the OS keeps crashing, Ive done a APPLE HARDWARE TEST everything fine, Ive used disk utility to check for problems everything fine, Ive contacted HITACHI not response (3 week have past by). Im runing out of ideas. HELP!
    Message was edited by: isaisos

    Hi,
    You say
    while OSX can easily be installed and booted from an external HD,
    Stefan
    Well I thought it should be easy, but I must be missing something. I bought a 100GB HD for a laptop that didn't turn out to need it, so I thought it would be good to install 10.4.11 on it so I could use it to start up coomputers having HD problems. I put it into a USB "slim carrier", plugged it into my iBook, put the install disk into the superdrive and clicked install. When the iBook re-started and the installation steps showed up, the drive showed up, but the install program showed the drive as a non-installable location.
    Is there another way to do this? Must it be in a firewire enclosure, or should USB work?
    Many thanks for any hints here,
    ...Tom

  • Fans are running at full speed after hard drive upgrade. Used same brand drive.

    My Western Digital 500GB hard drive crashed. The date on it is Aug. 2010. I swapped it out for a Western Digital Caviar Black 1TB. All plugs were identical including the temp sensor cable. My fans now run at full speed. What gives? BTW. This is th 3rd WD hard drive to fail at my office in multiple iMacs. I have a 21.5 iMac i3 3.06ghz. I have tried the SMC reset,.. no luck. Reset the PRAM,.. no luck. Hard drive and computer function perfectly, it just sounds like a loud annoying PC.

    After a little more research the only thing I found for 21.5" mid 2010 imac were three part numbers for three sensor cables which are a function of vendor:
    922-9215, Hitachi
    922-9216, Seagate
    922-9622, Western Digital
    The strange thing here is these are vendor specific and not model within vendor specific.  So you started with a WD drive and replaced it with different model, but still a WD drive.  So you would think it would require the same sensor cable. 
    Maybe the drives are different enough for this to matter.  Or maybe you should check the connections one more time.  Be it model of drive or connections, whichever it is, the sensor cable is the source of your problem.

  • Do I have to re-do BootCamp after hard drive upgrade?

    I currently have an early-2011 MacBook Pro with 500GB storage. I ran BootCamp and now have a partitioned hd with 300GB on my OSX side and 200GB on my Windows side. I'm running out of space and want to upgrade my hd to a 1TB hd and was wondering if the ratio of storage space would be the same after the upgrade or if I would have to re-do BootCamp and re-install Windows. I have been backing up my computer on an external hd and would be able to go back to the way it was before I ran partitioned it, and since only games are on the Windows side (mostly through Steam), it wouldn't be too hard to start from scratch and re-install the games. So basically this is what I'm asking: after upgrading my hd from 500GB to 1TB, will I have to do BootCamp all over again or will I be able to choose how much space I put on each side of the partition?

    There is a surprising amount of misinformation about this topic. I don't know whether the people who make Winclone are to blame, but if you look right across the internet you'd be forgiven for coming to the conclusion that the only way to move, restore or resize your bootcamp petition is to use paid software. This is simply not true. If you're willing to spend some time and follow a couple more steps, it's easy to install a new hard drive, and put both your OSX and WIN7 partitions back precisely as they were (or resize as you please) without using anything other than freely available utilities.
    The way I've come up with uses a 160GB Maxtor USB drive and a DMG image of your bootcamp partition stored on a networked computer. I intended to write these up with screenshots at some point. But for now here are my unedited notes.
    1 - use a utility called SuperDuper to create a bootable exact copy of your OSX partition - this is where the Maxtor external drive was used. One of the beauties of Apple OS - you can boot from a portable drive...
    2 - Use the Disk Utility (Applications - Utilities) to create a DMG of your bootcamp partition - move this to a networked computer
    3 - Create a bootable CD of the partition management program "GParted" by downloading and burning an ISO from their website.
    Next step depends on what you want to achieve - this assumes you're installing a new drive.
    4 - Install your new hard drive - plenty of videos around on how to do this, not hard.
    5 - Plug in the drive that you used to create a backup of the MAC OS and hold down option when turning on - boot from the external drive
    6 - Using the disk utility, create two partitions on your brnad new internal HD. Size doesn't really matter at this stage - just so long as one is big enough to fit the MAC OS
    7 - Using SuperDuper copy your MAC OS back onto the first of the new partitions
    8 - Before you restart, restore the DMG image you've stored on a networked computer (Images-scan for restore) to the second partition. It's important that you are still running off the external drive when you do this as otherwise you'll get a "resource busy" error when you try to restore.
    9 - Shutdown. Turn on holding down option. Fire up the GParted disk you made early. It's an ugly interface, but gets the job done. Just accept the default settings when asked questions when starting up.
    10 - Using Gparted delete any extra partitions that have may have crept in (I had a FAT32 200MB partition that was causing issues) - what you should have is only two partitions the HFS and the NTFS partitions. You can resize these to whatever you feel like. This may take some time. Moving partitions around on a 750GB new drive took about 4 hours. Shutdown and unplug everything.
    11 -  Turn on and hold option. Select the Mac OS hard drive and your OSX will start. At this stage you won't be able to boot into Windows - that comes in a moment.
    12 - Download and install ReFit. Go into system preferences-startup disk and and make sure that the Mac OS is selected. Restart twice. Twice is important - that's when you should be greeted with the ReFit screen when you restart the second time.
    13 - On the refit menu, select the option to the right of the command prompt icon (the partition tool) - it will ask you if it can sync the Mac boot table with the Win boot table (something like adding the MBR to the boot schedule) - say yes. It takes less than a second.
    14 - Restart - and again hold option. Grab your original Windows installation CD and boot into it. Select your region and then go to "Repair your computer". Ignore the message about being able to fix and restart (choose No). Then choose Startup Repair. It'll do its thing. You can then restart.
    15 - You should now have a working OSX and Bootcamp drive on your new hard drive - exactly as it was on the old one. Without dropping a cent on software and a great sense of achievement.

  • How do you install OS after Hard Drive upgrade? Thinkpad T41p

    I have a Thinkpad T41p with Window XP Pro on it.  I have a new larger hard drive for it, but I do not know how I will be able to install the OS on the new drive.  The laptop came with the OS already installed on it.  That will to be the case, of course, for the new hard drive.  So what do I do?  If you could point me to a step-by-step procedure, I would be most grateful.  I have installed numerous OSs, so I am familiar with how to do that from installation CDs. 
    Thanks in advance for the help.
    GKent

    Just went through this process on my wife's T41. I did the following:
    downloaded and installed the eval copy of Active@ Disk Image and Active@ Boot Disk (created a boot CD).
    rebooted to the BIOS setup and in the security setting for the IBM Predesktop Area I selected Disable saved the changes and booted
    rebooted to windows and usedActive@ Disk Image to create a raw image of the entire disk to a USB hard drive
    Shut down and removed the original hard drive and installed the new empty hard drive
    rebooted using the CD created by Active@ Book Disk and started the Active@ Disk Image utility
    selected the Image to Disk option. This took the raw image and installed it on the new hard drive (this included the hidden partition as well as the windows partition
    rebooted without the boot cd and logged in to windows
    rebooted into the BIOS and reset the security setting for the IBM Predesktop Area to Normal, saved changes and booted
    result is the same size partitions as before on the new 80 GB hard drive so I then ran Partition Magic to resize the Windows partition to utilize all of the remaining space on the disk (left the hidden partion in place - it is still bootable)
    rebooted and I now have a 74.5 GB drive for windows with all of the installed software intact
    I did plan on using the recovery option to reinstall the image to the factory settings since I had a few issues with windows on the original drive. Ran Rescue and Recovery and it could not find the restore images After much searching it appears that I will have to go out and buy the CDs (unless someone has a free download option)

  • Slow Startup after Hard Drive Upgrade

    I upgraded my hard drive in my iMac. I used a Western Digital Caviar Black 2TB Internal Serial ATA Hard Drive from Best Buy.
    I installed Snow Leopard and re-installed everything from scratch (didn't do a restore of anything but some limited data.) I installed Boot Camp and Windows 7. 1.5tb for OSX, half tb for Win.
    As soon as I boot camped it, the Startup became very slow. If I hold down the Option key to get to the boot menu, it takes nearly a minute to get to the menu. Previously, it just took a few seconds. Once I choose the boot menu, the boot time is normal.
    So the slow down is just getting to the point were boot camp decides which OS to boot. (Sure I'm using the wrong jargon, but hopefully that's clear.) Before the upgrade, it booted so fast you could easily miss the holding down the option key. Now you have about 30-45 seconds to press the Option key and not miss the boot menu.
    I have run the disk utility with no errors to report. Once it boots, everything runs well, in either operating system. To reiterate, it booted at about the same speed before the upgrade until I boot camped it.
    Also, I initially installed the drive and restored time machine, boot camped it, and restored Windows. This failed as the Windows full system restore screwed up the partitioning. So I started over from scratch. Everything installed normally again, but I'm just wondering if I needed to do some extra step, like a full format or other partitioning, to make sure the drive partition wasn't still messed up. I'm an old DOS guy, and to use those terms, I would have run diskpart and wiped out all partitions, created a new one, and formatted it. I'm not sure I did the equivalent of that in OSX when I re-installed it.
    Thanks for reading all that.

    That did help... but, turns out the main culprit was a failing firewire external drive. As I was sitting here, checking out your solution, I had the machine off about to reboot when I heard and felt a vibration in the desk. Fearing my installation of the new hard drive, I looked over the Mac to see a very old WD MyBook vibrating on the desk. I unhooked it and booted and it came up at normal speed. So you indirectly solved my problem, thanks.

  • How to reinstall OS after hard drive upgrade?

    I Just installed a new hard drive and RAM on my MacBook 2010 white. I have the original OS disc but don't know how to install it (no instruction booklet). Any tips on what to do? Please and thanks

    Thanks Niel. I was able to get it running but then it did not recognize my new drive (Crucial MX200 SSD). Apparently it's not initialized and I was told I have to remove it, connect it to an outside source with an OS and format it that way. I may have to return it to MicroCenter but I don't want to drive back there. Any suggestions or is that my only course of action? Thoughts?

  • Download Boot Camp again after hard drive upgrade?

    This is just a quick question. If I put a new hard drive in my MacBook, will I have to get Boot Camp again, or can I just partition the drive before I reinstall Tiger, and just install Windows with the driver CD I already have from last time? And I suppose I would also like to know if I have to get Leopard in order to get Boot Camp.

    You would need Boot Camp and currently it is offered only with Leopard. Not sure if you could install it on a separate non Boot Cam partition and get it to work right.

    I have a HP Pavilion G7000/ G7015EA laptop, and after getting a WARRANTY ID - ERROR CODE 10008 on a hard drive self scan,HP told me I need to replace the hard drive. So I would like to upgrade to a faster 7200rpm and 250/300gig HDD(5200rpm - 160gb now fitted).But I have read on the net that you sould check if the BIOS will support a larger/faster HDD.The unit runs windows vista home premium(32bit) and has 2meg ram and I have installed BIOS version F.34, does anyone know if it will run/support a larger/faster HDD or how I can find out, before I buy the new hard drive.I am quite new to all this stuff and only learnt this in 3days any help is appreciated!!!!!!

    Hello. I too own an hp g7XXX series laptop and wanted to upgrade the hard disc drive and graphics capabilty.  The hp G7xxx series uses an IDE  bus as opposed to a SATA interface. Upgrading the Hard disc is easy as long as you have a copy of the full operating system on CD.  If not try to find a friend or colleague that has one. When you do install the new IDE drive by unsrewing the two screws inthe labeled cover on your laptop.  unplug the old laptop and plug in the new one (with the laptop switched off.) Screw the cover back on and power up the laptop, with the bios screen available open the bios (del key or F1 or F2) then change boot sequence to boot from CD and install Vista from here with the product key on the bottom of your laptop.  You will need to call INDIA microsoft to activate the system but this is almost hassle free (but not required) then voila!

  • Ive lost iphotots and iweb after hard drive failed help

    Hi my hard drive failed yesterday and I took it to the apple store who confirmed it had failed.  They advised I should purchase a new one, provided me the specs and fit it myself.  I've now clearly done that because I'm writing this
    However I've reloaded everything back on but i've noticed my iphoto and iweb are missing!!!  I really need these apps, I cant remember how I put them on the machine, be it disc or download but clearly ive paid for these app.
    Please please help me I really need these apps as I have current workload dependant on having these apps

    iPhoto is included with the iLife apps and can be downloaded from the Mac App store or if your Mac is slightly older and came with an earlier version of OS X then Mt Lion then those apps are on the second system install discs that came with your system (Which I suspect it is an older Mac as iWeb is no longer included in the iLife suit of programs).
    So dig out your original system discs and use the one marked Applications to reinstall those apps. Then update them from software update.
    If for some reason they won't install on Mt Lion then you will need to wipe the drive, Re-Install the original OS X version and the iLife apps then upgrade back to Mt Lion.
    EDIT, NOTE: To the OP and DS store.
    iWEB Still works on ML as long as it is updated to the newest version. If the Applications disc is new enough it will even install on Mt Lion.
