Toshiba hard drive issues...

Okay, per Apple discussion forum rules, this is going to be a technical question.
Toshiba states the Mean Time To Fail (MTTF) of the MK4006GAH to be 300,000 power on hours. This is the 40gig drive used in the 4G 40gig iPods. They also claim a product life of 5 years or 20,000 power on hours. These numbers are way higher than that being experienced by thousands of us who bought these expensive little machines. Look in ANY iPod related forum to find these HDD deaths are widespread.
Are these problems directly related to Toshiba faulty manufacturing? If so, many of us need to lean on Toshiba to fix this. If not, what has Apple done to shorten the lifespan on these drives?
What can I, as a consumer of iPods and Macintosh computers do to extend the life of this unit? When my hard drive starts with the now infamous "whirr click whirr click", what are the steps to recovery?
The suggested remedy here on the Apple forums and in many other forums is to drop the ipod from approximately waist height to a carpeted floor. This is supposed to jar the hard drive back into proper action. This is unacceptable.

he MTTF and similar operating life projections are probably based upon the drive being used in a more benign environment than an ipod
ipods can get bounced around quite a lot, this will increase the chance of failure
that said, the 40gb is in my opinion a lemon, i had one fail inside a week of purchase so i just took it back for a refund and got a smaller one
on the forum there seem to be a disproportionate number of 40gb failures reported vs. reports of smaller units that were sold at the same time
the 40gb has more platters and a higher mass head assembly than the smaller units of the same family of disks, this would make it more vulnerable to damage

Toshiba Satellite a505-6005 hard drive issue and questions regarding options I may have

Issue: start up computer and windows does not start. It eventually goes to a startup repair screen and eventually says "resolving disk errors...", and that's if it even gets to that screen. Unfortunately I never made a recovery disk or system image discs (I know that was not smart). I did however kept my files backed up so that was good.
Steps I took: Took it to Best Buy and the tech advised me that the Black Tie 2 year protection had expired on Jan 30th 2012, and so it could not be repaired for free. I asked the tech there how much it would cost to fix and they had advised me that it was most likely a hard drive issue and that it would cost nearly $400 to replace/fix it. So I decided to buy a new Asus K53E-BBR14 laptop since it was not much more. When I got home and loaded everything up and got the computer to how I want, I went ahead and made a recovery disc and system image disc's. I tried using the recovery disc that I had made with my Asus in the Toshiba laptop and boot it from the dvd drive and it did not get anywhere. So I ASSUME that it really is a hard drive error because the RAM worked just fine in my new laptop and "repairing disk errors.." means something is wrong with the hard drive:
Now that you know the background of what has happened my questions are as followed:
1. Can I buy a new hard drive for the Toshiba and use the recovery and system image disc's i created on the new hard drive that i install in the toshiba? and just removed the bloatware from Asus (or does that not even get added to the disc's I created)?
2. If so, will it prompt me to enter the Windows 7 product key? and therefore using the product key located on the bottom of the toshiba?
3. What other steps could I take to make this toshiba laptop salvageable? This way i can turn around and sell it.
Thanks,
Russell States

Also,
I noticed that i can purchase (well pay the shipping anyways) recovery media from Toshiba. Can I use that on a new hard drive installed in the toshiba?
BTW ran the Windows Memory Diagnostics Tool and no problems were found with the memory. and i do not care about the old hard drive as I have MY files backed up. I just want to try to get this toshiba laptop back to being "like new".
Thanks,
Russell

PB 1GHz Hard Drive Issues?

Hi, Just bought a used powerbook 12" 1GHz (no battery, missing a few keys). First time I started it, it booted properly, showed the 80GB Toshiba hard drive and SMART showed "verified." Since then, it rarely will boot (doesn't see the hard drive). Moreover, putting it in firewire target mode to use as an external disk, the internal drive generally does not show up. When I've been able to get at it, I've run Disk Utilities and Diskwarrior on it "successfully," but still generally cannot get it to show up. When I can't get at it, I've tried a pram reset, but no luck.
I intend to open it up and get at the hard drive to see if there is a loose/damaged connector or if the hard drive will work externally. I'm hoping it is not anything having to do with the logic board.
It will boot from an external hard drive (my Albook 15 in firewire target mode).
In the meantime, are there known issues that anyone could point to that would explain my problem? The model has been around awhile, so I'm thinking others might have had this problem show up.
Also, any cheap sources of replacement keys?
Thanx! Jeff

Welcome to Apple Discussions, Jeff.
It does sounds like the Toshiba drive might be dead (not an altogether uncommon thing) or that the data cable is either loose or damaged. I don't think the logic board is the problem as you have been able to run the PowerBook from an external FireWire drive.
As for replacement keys, PBParts.com do sell them.

Sometimes my computer takes too long to connect to new website. I am running a pretty powerful work program at same time, what is the best solution? Upgrading speed from cable network, is it a hard drive issue? do I need to "clean out" the computer?

Many times my computer takes too long to connect to new website. I have wireless internet (time capsule) and I am running a pretty powerful real time financial work program at same time, what is the best solution? Upgrading speed from cable network? is it a hard drive issue? do I only need to "clean out" the computer? Or all of the above...not to computer saavy. It is a Macbook Pro osx 10.6.8 (late 2010).

Almost certainly none of the above! Try each of the following in this order:
Select 'Reset Safari' from the Safari menu.
Close down Safari; move <home>/Library/Caches/com.apple.Safari/Cache.db to the trash; restart Safari.
Change the DNS servers in your network settings to use the OpenDNS servers: 208.67.222.222 and 208.67.220.220
Turn off DNS pre-fetching by entering the following command in Terminal and restarting Safari:
defaults write com.apple.safari WebKitDNSPrefetchingEnabled -boolean false

Hard drive issues after update 10.10.3

Question also posted here:Hard Drive Issues (Both new and old)
I'm trapped in a HDD nightmare with my MacBook Pro mid-2012.
I updated to Yosemite 10.10.3 (with the Photos app). A couple of days after the update, I was watching a movie on my TV screen via HDMI. In the middle of the movie I removed the HDMI cable from the MacBook Pro and everything freezes. I forced shut down (Note: My HDD was encrypted). After I forced shut down, I tried to turn on and the loading screen would never stop loading - like, 14 hours stuck with the progress bar. Since I have backups, I decided to access DU and format my HDD. I tried everything. For real. Every command line I could type on Terminal to format, repair, erase and/or partition. I read almost every issue-related questions on the forums and stack exchange groups for a week (even posted my issue here: http://apple.stackexchange.com/questions/181090/erasing-and-partitioning-hard-dr ive-from-internet-recovery?noredirect=1#comment215695_181090).
So, I decided that it was a HDD failure and bought a new one.
I bought the Seagate 1TB SSHD Hybrid - ST1000LM014. Installed the new fresh disk and guess what? All those same problems again. I´m not able to restore from Time Machine because it doesn't recognize the disk in the restore page. But the disk is recognized in the DU. When I try to erase or partition the new SSHD, the same old errors: File system formatter failed. Yes, I tired GUID Partition Table, all of the security options, etc.
Please. Any light that you can throw at this issue, I'll be very grateful for. BTW, the new SSHD is recognized and the SMART Status says: Verified.
Any ideas on *** is going on?
Thanks in advance!
MacBook Pro (13-inch Mid 2012), i7, 8GB RAM

After I erase the hard drive (I assume one pass of writing zeros is good enough, 7 passes not needed?) do I turn off the laptop, then turn on and insert the Install Disk? Will there be a prompt telling me when to put in the disk? Or do I put in the disc right after erasing?
One pass is fine. If you've previously backed up your hard drive to an external hard drive using SuperDuper!, which is what I use and recommend, or another program, if it created a bootable drive, you want to boot off of it, bring up SuperDuper! and copy the drive back to the internal hard drive. SuperDuper also makes the drive bootable. When done, reboot, and you should be all set. If you're using Time Machine, you'll want to install the operating system, then restore the Time Machine backup. SuperDuper! is available from http://www.shirt-pocket.com/superduper/superduperdescription.html
Finally- should I update the OS? Is there a problem with the newest update that caused this crash, or was it just a spurious glitch/bad luck?
I've been running 10.5.8 for awhile with no issues, and would recommend moving to it.

How do I find my tab history? I had hard drive issues and when I launched my browser after getting it back their was no "restore session" option. I know a tab history is kept, just don't remember where or how to exercise it. Thanks

Firefox 4 saves the previous session automatically, so there is no longer need for the dialog asking if you want to save the current session. 
Use "File > Exit" or "Firefox > Exit" if you want to restore multiple windows. 
You can use "Firefox > History > Restore Previous Session" to get the previous session at any time. 
There is also a "Restore Previous Session" button on the default about:home Home page.
Another possibility is to use:

Incredibly slow MacBook, Internal Hard Drive issues...

Good morning everybody! I'm apologize if this post is extremely wordy...
I am extremely baffled by a particular issue with a MacBook 2.0GHz C2D which belongs to a friend of mine. The warranty is expired.
_Brief history:_
Several months ago, this MacBook could not find a bootable volume. The drive would not mount when booting from an external FireWire hard drive. It would not mount when the MacBook was put in Target Disk Mode and connected to another Mac. When booting from an external USB hard drive or with my MacBook Pro connected to the MacBook via Target Disk Mode, the MacBook booted up quickly. I came to the conclusion that the internal hard drive must have failed and needed to be replaced. Ultimately, the data was not recoverable from this drive.
I then proceeded to swap out the defective Apple OEM Seagate hard drive with a known working Apple OEM Fujitsu hard drive. When booting from the Leopard Install DVD, the MacBook would boot incredibly slow, but would finally reach the Installer Language screen. When proceeding to install Leopard, the drive would take a very long time to have data written to it, and ultimately the install failed. I removed the new hard drive from the MacBook and placed it in an external USB enclosure, attached it to the MacBook and booted from the Leopard Install DVD. Leopard would install successfully. I removed the hard drive from the enclosure and reinstalled it the MacBook. When booting from the freshly installed OS, the MacBook would take a very long time to boot. The MacBook is extremely slow!!!
I checked the Activity Monitor to ensure CPU & System Memory Usage was not going crazy. All Processes where normal with adequate CPU & Memory headroom.
I took the MacBook apart thinking that the SATA Controller Cable might be loose. No, it was firmly in place. I reassembled the MacBook and booted it up again. Still incredibly slow!
Finally, after several reboot attempts, the MacBook would book up quickly and operation was perfect. I applied all updates and continued testing the MacBook with great success. Gave my friend his MacBook back and he was grateful.
_Now for the kicker..._
My friend brought me his MacBook a week ago complaining that the MacBook was operating extremely slow (much like when I was initially testing it before). I verified the MacBook was slow when I tried using it. I tried several reboots and then it would get stuck on the gray Apple with spinning gear.
I tried booting into Single User Mode, but it gets stuck on "Waiting for root device"
I put the MacBook in Target Disk Mode and connected it to my G5 2.0GHz Dual Core. The hard drive would mount quickly on the G5 and I used Disk Utility to create a Restore Image. The disk operation would perform normally and the image would be created successfully.
I then partitioned the MacBook's hard drive when connected to the G5, ejected and proceeded to attempt OS reinstall. No dice! The hard drive is not even detected by the Disk Utility on the Leopard Install DVD.
Finally after several reattempts, the hard drive is recognized, but is extremely slow when trying to reinstall...and again, ultimately install fails. Using Disk Utility from Leopard Install DVD, the hard drive fails to unmount when I try formatting.
I don't have Apple Hardware Test disc for the MacBook or Apple Service Diagnostics disc for this model. Running TechTool Pro shows hardware to be okay, disk controller onboard the Fujitsu drive is okay, but running SMART & Surface Scan takes a long, long time (which I'm certain will ultimately error out). Running Drive Genius takes a long, long time as well.
Conclusion:
I think the SATA Controller Cable is defective. I can't think of anything else that would cause disk errors or performance issues like this. Your input is truly appreciated!

Even though no one responded to my post, I thought I'd share the resolution with the entire Apple community. I hope this information will be helpful to some of you with MacBooks or MacBook Pros that may be running painfully slow or may be exhibiting hard drive issues because your machine won't recognize the boot drive or fails to properly boot on a perfectly healthy S.M.A.R.T. verified hard drive. It just might be the hard drive connector/cable. Here it goes...
I visited my local Apple Retail Store and asked a "Genius" at the Genius Bar about this issue and told him my thoughts about a possible failed hard drive connector/cable. First, he didn't even know what a hard drive connector was! Then, he arrogantly stated that he never heard of such a thing and that these cables never fail. Finally, he blatantly dispelled this as a possibility.
On the contrary with my experience, I have had many failed PATA controller cables that required replacement when supporting the desktop PC's at work. I have personally owned and supported many Apple manufactured laptops and desktops and have never encountered this issue on a Mac...until this MacBook!
So, after looking at the Service Manual for the MacBook, I went over to my local Apple Authorized Service Provider and purchased the Hard Drive Connector Apple Part #922-7579. I replaced the original cable, reassembled and proceeded to boot the MacBook with the Leopard DVD installer. The Fujitsu drive was immediately recognized and was able to be formatted and Leopard installed without incident. The MacBook boots off the internal hard drive as normal again and works nice and fast again.
Thank you all for your time!
:D

How to Format Toshiba Hard-Drive for Mac with Parallels?

Hello,
I recently bought a Toshiba Hard-Drive with the following features:
500GB
It is a Canivo Basics 3.0
It is USB 3.0 and 2.0 portable hard drive
It has already been formatted NTFS for Windows XP, Vista, 7, and 8
The box says that it can be reformatted for Mac
I have a Macbook Pro with Retina Display that I bought this year in late March/early April.
It runs OS X Mavericks, and Parallels Desktop 9 for Mac.
I would like to reformat it so that I can use it on my laptop both with Windows and Mac OS at the same time. I do not wish to use a partition as I want to access the hard drive through Mac and Windows at the same time on my laptop and I also want to be able to access the Mac things on a Windows computer and vice versa.
I have never formatted a hard drive before, and I would like to use a completely safe software, or no software at all, if it is possible.
I am sorry but I don't have a very high knowledge of this.
Thanks,
Sandy-Wood

It would be easier, using Parallels, just to format the drive for "Mac OS Extended (Journaled)". You can see it both in the Windows/Parallels and the Mac side. Leaving it formatted as NTFS is not going to allow you to access (write to) the drive unless you use third-party software. Formatting it for Mac lets you use it, as I said, on both the Parallels VM and the Mac side.
If you were using Boot Camp, I would advise leaving it formatted as NTFS and purchasing NTFS for Mac to access the drive on both OS's. You can mitigate that by formatting the drive for Mac:
Good luck,
Clinton

Permissions Issue, Colour Wheel, Hard Drive Issue??

Hi!
I have had issues with my mid 2009 MBP recently and I'm wondering what the best way to fix them would be.
First off, I have some major permissions issues with my accounts. I am using 3 different users regualrly on the same machine and needed to access files from the home folder so I changed them a long time ago, and am not sure how to fix that. I have repaired the permissions countless times in the disk utility and it seems like there's always loads more to do each time. When I varify the disk, it says its all okay.
Secondly, I have had the machine freeze on me several times while doing very little on it. This happened awhile ago, and thought that it was just the permisions thing and so I did that again, and it started working better, for awhile. It would go a few days or weeks before doing the same thing, sometimes not even getting past the apple logo on startup before freezing. This makes me think it may be a hard drive issue???????
This morning, I tried dozens of times to boot, with no success at all..... until about the 25th time when it miraculasly booted. I have run permissions repair a few more times and it seems to be working okay at the moment, but the problem seems to be happening more often over time.
To complicate matters, I am traveling at the moment and will not be home for several months. I purchased an external harddrive last night and was able to successfully back up my data.
Question 1: Is it the permissions that are causing these problems, or is it related to something else. The computer seems to work fine when its working, and then once in awhile, decides its not going to do anything.
Question 2: Would upgrading to Lion (currently running 10.6.8) fix the permissions issues or just carry them forward? I would like to consolidate the 3 users into one, if that would solve it. Does the migration utility preserve permissions or does it give you a brand new start?
Question 3: If neither solving the permissions or the OS upgrade would fix the problem and it does need a new harddrive, is it possible to buy one and install it myself? I do not have apple care left on this machine and am on a very tight budget. I am used to taking things apart and all that as part of my job and it seems simple enough. Where can you buy a replacement??
Hopefully someone out there will be able to help me out on this one.
Cheers!!!!
Brian

Disk Utility permissions are separate from User account permissions.

Disk Utility will always show something to be needing repair, but that's ok

Verify Disk is good, that's a good thing.

Your data is backed up, hopefully not with TimeMachine alone, but if you did, then get another drive and backup data manually to that as well. If the TM drive gets messed up, it's a pain to get your data off of it.
Question 1: Is it the permissions that are causing these problems, or is it related to something else. The computer seems to work fine when its working, and then once in awhile, decides its not going to do anything.
Well you could call Apple for replacement 10.6.x disks, and just reinstall 10.6 and bundled programs, but this can kick out kext files out of the /System/Library/Extensions folder installed by some third party software.
This method fixes OS X, but doesn't touch your files or most programs.
Nor will this method fix your Users accounts if the issue is in there.
A creation of a new user, then deletion of the others, return files from backup (set permissions) will fix User folder issues if the above user permissions fix doesn't work.
(Of course you could wipe the drive from the 10.6 disk, but you have to install all software again)
Would upgrading to Lion (currently running 10.6.8) fix the permissions issues or just carry them forward?
No, you don't want to install Lion, it won't fix those issues in User folders, not only that Lion has it's own issues and doesn't work with a lot of older software etc. No use clusterfscking a already bad situtation when it's seems it's only localized to the User accounts.
I would like to consolidate the 3 users into one, if that would solve it.
Yes that could very nicely and tidy up things in the process.
What you do is transfer all files to one regular powered storage hard drive.
(Don't use/disconnect the TimeMachine drive for this as it preserves the users seperated and you don't want all those users back restoring with Migration Assistant)
Create the New User on the machine as Admin, log into it and delete all the other Users, transfer all your files back from the regular storage drive, changing all the permissions to yourself before placing them into their respective folders as they will have three different permissions.
Notes:
If you have a extensive iTunes playlists on one User (say #1), then create the new user with that same name (will require some work, create User 4, delete Users 1-3, reboot, create User 1, delete User 4) then transfer your iTunes folder to Music of that User 1 (same name as before). This will preserve the pathnames of your song locations and your playlists will be preserved.
(before you ask, no you can't combine playlists)
Also if you have photo's in iPhoto Library, you have to right click on it and "show package contents" inside is a folder called Originals, copy them out and import into the iPhoto of the User #1.
Does the migration utility preserve permissions or does it give you a brand new start?
Yes it preserves user permissions, no it doesn't give you a brand new start. Only a fresh install, creation of new users and then just transferring of files does that.
Nothing about TimeMachine or Migration Assistant gives one a "fresh start", it's if hosed, so is your restore.
If you want that sort of pristine protection, you need to clone your ideal boot partition/drive using Carbon Copy Cloner (free/donationware) occasionally as a hold the option key bootable drive, then you can erase and reverse clone the pristine saved clone.
One can also update the clone on occasion, this way keeping the clone pristine.
I maintain 3 clones time dated, even have my boot drive partitioned 50/50 and auto-cloned, this way I have two boot partitions on the road and two externals at home.
I never use TimeMachine, it's not bootable (well it is on 10.7.2 only to restore though)

To delete files from your external HDD, attach it to your MBP and drag the unwanted files to trash and then empty trash.
Then you select the files that you want to transfer by 'drag and drop' to the external HDD and trash the files on your MBP.

Switching iTunes (older version) from an old latptop with mechanical issues to iTunes on a new computer. The hard drive, issue free, was placed in external drive enclosure. How do I recover iTunes?

I'm trying to moves iTunes (older version) from an old latptop with mechanical issues (non working screen, keyboard, and battery) to iTunes on a new computer. The hard drive, issue free, was placed in external drive enclosure. This was a cost effective way instead of dumping lots of money in an outdated old laptop while I can invest it into a new laptop. How do I recover iTunes?
I'm switching from a 3G phone to a blank 4GS in the process. I would like to have everything that was on my 3G phone and iTunes on my new phone and computer.
Thanks

iTunes: How to move [or copy] your music [library] to a new computer [or another drive] - http://support.apple.com/kb/HT4527
Quick answer if you use iTunes' default preferences settings: Copy the entire iTunes folder (and in doing so all its subfolders and files) intact to the other drive. Open iTunes and immediately hold down the Option (alt) key (shift on Windows), then guide it to the new location of the library.

My Macbook Pro OS 10.7.5 will not recognize toshiba hard drive. I will register on an iMac running the same OS. Any ideas?

I have a Toshiba external hard drive that i used with MacBook. I now have a MacBook Pro running OS 10.7.5. It does not register that the Toshiba hard drive is plugged in, yet if I plug it into an iMac running the same OS it does work.

I don't know the answer to your problem, but until you resolve it do not upgrade OS X.
I would suggest you try a reinstall:
Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. 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 then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
Reinstall Lion, Mountain Lion, or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless.

Has anyone else been having hard drive issues with 13" MacBook Pro barely a year old?

Has anyone else been having hard drive issues with 13" MacBook Pro barely a year old?

Yes, BUT...
... there are many problems that are really easy to eliminate by replacing the Hard drive, including ones that have nothing to do with actual Drive Hardware failure. These include corrupted install of Mac OS X, its EFI partition, clobbered partition tables, or the appearance of Bad Blocks in a critical area.
Any of these problems can sometimes be eliminated by re-initializing the entire drive and writing Zeroes, and re-installing from scratch. The trouble is, this process takes hours to complete, and is not guaranteed to be successful -- you may still need a new drive after all that effort.
I learned from my Plumber that consumers have no appetite for solutions that might work, and detest return visits for any related problems whatsoever. You or your friend may have had your drive replaced, not because it actually failed, but because the situation was troublesome, and the provider thought you would not tolerate anything less than a crisp, complete fix on the first attempt. And based on the cost of technician time, it may have even been cheaper that way.

Do i need to shut down my macbook pro before carrying it around? Considering hard drive issues

I am a uni student. I have a MacBook Pro early 2011. been using it for 3 years now.
i have a couple questions just out of curiosity.
do we really have to shut down our mbpro before carrying it around?
couldnt we just leave it sleep mode?
i mean, is it harmful to our hard drives if we put our mbpro in sleep mode and move it around?
does apple have a mechanism that kinda "stops" the hard drives from spinning in sleep mode?
I wanna know for sure, since some told me that it's okay to move my mbpro around in sleep mode, and some told me that it's not okay and i have to shut it down first.
i did occasionally transport my mbpro in sleep mode.... and i think.... i'm having some hard drive issues.
Thanks before for your kind answers.
Best Regards,
Moses

Moses,
your MacBook Pro has a sudden movement sensor which will park your disk’s heads in case it senses a sudden G-force change. By default, this sensor will be active. Carrying around your MacBook Pro while it’s sleeping (and applying some common sense while doing so) should not be harmful to its hard drive.
