IMac 27" late 2012 3TB hard drive bad blocks

Hi Guys,
I just received the new iMac 27" late 2012 with 3TB hard drive and as soon as I run Drive Genius version 3.2.2 I saw that the drive has 8 bad blocks.
I tried to deleted the logical volume and reinstall the OS X 10.8.2 and after a scan I got the same 8 bad blocks. I give it another try and erase the entire 3 TB volu except the recovery partition and installed Mountain Lion and after running another Drive Genius SCAN for almost 12 hours I got 8 bad blocks again.
Called Apple Support and they are clueless about what is going on as they are not even aware that the late 2012 iMac 27" is not even in stores yet.
I was told that as long as I do not have errors within the OS X I should not worry about as he HDD is fine. I do not believe it since from my experience when you have a bad block you also have a physical damage on you disk surface.
I called Apple Support again and I was told to go to Genius Bar and have them to replace the HDD to a unit not even a week old. I think that I am going to return the unit, maybe I got a lemon and the unit got dropped during the shipping process or who knows.
I hope that this thread will help other owners to have them to run a check disk or scan disk just to make sure that they do not have a bad hard drive on their new iMac late 2012.
Again I have nothing against to anyone as I just hope that someone from Apple will find this thread and try to prevent this from happening to a large scale.
Thank you.

Drive Genius will report bad blocks when none are present. It may even be responsible for disk corruption.

Get rid of Drive Genius. Do not install such junk on a Mac.

IMac 27" late 2012 3tb Yosemite BOOTCAMP ISSUES

Hi,
As said in the title, I have a 27" iMac late 2012 with 3tb worth of storage... It is currently running the latest version of Yosemite.
I have been trying to run bootcamp on the iMac for windows 8, however it is not allowing me to install windows...
It Is coming up with an error saying it is unable to partition the hard drive...
I Have tried to create the Partition via disk utility yet still am not able to perforn what I need it to do...
i Would really appreciate any help or ways to run bootcamp...
Thanks,

Can I use a 3TB Hard Drive in my iMac mid 2010 27" ?

I am updating my system with SSD and I want to replace the stock HD with a 3TB Hard Drive. It's an Hitachi HD.

Maybe...but the problem is heat. You can always add it externally via Firewire using a Newertech Voyager.
http://www.macsales.com may be able to install it safely in your machine as well. They also offer an option to add an eSATA port on some iMacs. Check with them what your options are.

Same problem here - only with a 2012 Macbook Air running 10.8.2
(very accurately described above )
After MBA sleeps and you try to wake it up, screen does not refresh properly and only refreshes where the current mouse cursor is.
If you close the lid, and then re-open the MBA then functions correctly.
I also have an issue where the MBA will suddenly crash while asleep and then will require a hard reset.
Not sure if related though.
I just reset smc/pram - will report back if this does not solve the issue.
If you don't hear from me again, then reseting solved it!

IMac 27" (Late 2012) Freezing and Crashing

I purchased an ex-demo iMac 27" (Late 2012 - 3.4Ghz, 3TB Fusion Drive, Nvidia 680MX 2GB) that was upgraded to 32GB Ram last July.
Since I've recieved it it has intemittantly locked up, occasionally you get the your computers been restarted screen but mostly it just freezes completely. There's no pattern it can be at the login screen, on the desktop with no software running or when any software I use. There's no particular thing that seems to cause it.
I have run the Apple Hardware Test in Extended Mode Multiple Times and it reports no issues. I've run MemTest Continuosly for 24 hours and it reports no issue.
I've done clean installs of OSX multiple times (both Mavericks and Mountain Lion) and its had no effect. Even with a barebones OSX install it still freezes so I've ruled out software.
I've switched the RAM to rule out memory - still freezes.
I've used both WiFi and and Ethernet to rule out network - still freezes.
I've removed the Fusion Drive Logical Volume and installed OSX to the SSD and then to the HDD to rule out hard disks. This included zeroing the hard drive to ensure there was no bad sectors etc. This didn't make any difference.
I contacted Apple who told me to take it to an Apple Store or Apple Authorized Service Provider. I took it in to my local AASP they've told me they can't find anything wrong - everything works fine for them.
I'm wondering whether the issues are environmental. I've seen a few reports that "Dirty Power" can cause issues, has anyone had any similar experiences that have been solved by a UPS?
Failing that I'm at a loss at what to do. The iMac is unusable as it freezes every few hours.
Anyone have any ideas of what else I could try?
Thanks,
James

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve your problem.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to gather information about the state of your computer. That information goes nowhere unless you choose to share it on this page. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger on a public message board. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them.
Here's a summary of what you need to do: Copy a line of text from this web page into the window of another application. Wait for the script to run. It usually takes a couple of minutes. Then paste the results, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in your browser, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign ($) or a percent sign (%). If you get the percent sign, enter
exec sh
in the window and press return. You should then get a new line ending in a dollar sign.
Click anywhere in the Terminal window and paste (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know your password, or if you prefer not to enter it, just press return three times at the password prompt.
If you're not logged in as an administrator, you won't be prompted for your password. The test will still run. It just won't do anything that takes administrator privileges.
The test may take up to a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line "[Process completed]" to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report your results. No harm will be done.
8. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If it happens, please post the test results on Pastebin, then post a link here to the page you created.

Installing Windows on 3TB hard drive in Lion

I have attempted to follow the instructions set forth by twocanoes.com (http://www.twocanoes.com/support/winclone/installing-windows-via-boot-camp-on-a- large-%282.2-tb-or-larger-%29-drive-in-lion-%2810.7%29-and-later). I just purchased my new 27" iMac with a 3 TB HDD. Well as I already now know, that is the root of the problem. And apparently for some reason Boot Camp will not work on 3TB mac. But I encountered a secondary issue when attempting to use the work around that twocanoes had found. When attempting to create a 3rd partion (creating 3 1TB partions as told to do so by the instruction) I am only able to make 1 partion. I only have the option to remove it. I cannot add a 2nd partion to make my 3 equal partions. Can someone please direct me to a resolution to create my third partion.
From what I have already looked up it is an issue relating to Lion. Any help would be appreciated. Suggestions, link, anything!

You are right.
As you have said that you can't make more than two partitions, are you sure that you order an iMac with a 3 TB hard drive and not an iMac with a 3 TB Fusion Drive? I say this because a 3 TB Fusion Drive doesn't allow you to create more than two partitions.
If you bought an iMac with a 3 TB Fusion Drive, see > http://www.twocanoes.com/support/winclone/installing-windows-on-a-boot-camp-part ition-on-a-3-tb-fusion-drive

Windows 7 failing to install through bootcamp on iMac 27" late 2012

Hello.
I have recently received my brand new iMac 27" late 2012, and am trying to get it to install windows 7.
My machine is running 10.8.4 with a 3.4 GHz Intel Core i7, 16 GB DDR3 RAM and 500GB SSD drive.
I launched bootcamp and went through the usual bootcamp standard steps, and after it partitions and restarts, the windows installation stops at the point of choosing a partition.
To elaborate, after the windows setup starts, and I click install windows, it asks me to choose a partition. It happens to be Partition 4 BOOTCAMP (the one that bootcamp supposedly prepared for windows as an NTFS partition.
It does not recognize it as NTFS. I click on advanced options and click format, but it takes a split second and never really formats. The only thing that changes at this point is the name of the Partition (the word BOOTCAMP disappears from the partition name). Another thing I tried after reading full threads for 4 days straight is that I click delete to delete the partition, then on the now unallocated space partition, I click *New to reallocate/format the partition. It also takes no time to turn this into a partition supposedly ready for windows, but it never allows me to choose it and go next to start installation.
I have done this about 8 times now and I am starting to worry about damaging my SSD because of all the partitioning and unpartitioning.
Here are a list of things I have done:
1. made an ISO image of the windows 7 (64 bit of course) and ran that on a USB
2. downloaded the ISO image from the microsoft website and ran that on a USB
3. used an exernal optical drive to run the windows setup using the windows installation DVD instead of the USB ISO image.
I have made sure everything is fully updated, had a friend install windows on his macbookpro retina with an SSD running the same OSX and it worked just fine.
*a small note that may or may not be of importance is that when in the list of partitions in the windows installation I click on Load Driver, it does not detect any drivers although the USB with the drivers that BOOTCAMP created earlier on the Mac side is inserted in the machine and detectable.
What is it that I'm missing?

SOLVED IT!
after 5 full days of research and trial and error (only error and no progress) and after I had hit almost every wall there is, I thought of reviewing all the elements that make up the set up.
1. iMac
2. windows 7 installation (i had both optical drive for the dvd as well as an image on a USB)
3. usb stick with the drivers on it.
the iMac i trust.
windows i doubted. so i went ahead and checked the format of the usb on which i had the drivers. weirdly enough, both were exFat, which is created by windows - supposedly.
I decided to change the format of the USB with the drivers on it to FAT. re-downloaded the drivers on it and restarted... and it worked !
Although it does not make sense at all, but windows was reading from the image on one USB which was exFat, but was not reading the drivers on the other USB.
My guess is that the reason is the Mac OSX was reading the windows through the exFat and that was working, but the windows was not being able to read its own format on the other USB. Typical windows weirdness.
In any case, I hope if someone has the same kind of trouble they would be able to benefit from this post.
Also, maybe its worth noting in the instructions of BOOTCAMP.
Thanks for those who took the time to read it.

Graphical artifacts with DX11 (and OGL4) on imac 27" late 2012 GTX 675 MX

Hello, dear community! I have the imac 27" late 2012 with graphical card GTX 675 MX.
In Mac OS X 10.8.5 all works perfect. Software, games (Bioshock Infinity), benchmarks (heaven 4.0). But in windows...
I was installed Windows 8, then 7, then 8 again, and every time after installing nvidia drivers (with BootCamp, or manually downloaded from nvidia site) i have some graphical artifacts ("||" randomly on the screen). On win 7 it was only in games (like Bioshock Infinity or Tomb Raider), on win 8.1 everywhere(on desktop and in games). In DX9 games (like World Of Tanks) all perfect, in DX10/11 games (BI or TR) - artifacts. After thousend of tests i run Heaven Unigine 4.0 with OpenGL(other settings the same) in macos and in windows(on 7 and on 8), for checking some hardware issue if it exists. But on mac os x, as i already said, all is perfect, but on windows - randomly appers artifacts.
I record a video to illustrate my problem. http://www.youtube.com/watch?v=AwEog66vfFk&feature=youtu.be
Help me please! People in service told me that this is not a guarantee issue

I assume you have GPU-Z and other tools to look at gpu. the imac falls between notebooks and desktops when it comes to graphics. and it may be some programs just are not written for that graphic device? possibly?
I've been on Windows 8.1 mostly along with 8.0 and graphic drivers have been "bumpy road" at times and I was able to swap out and use different graphic cards on my PC - had me thinking I had an SSD related issue, then replaced memory (those were bad it turned out, and could have caused drivers and system errors).
Windows has memtest on the DVD and I have seen one or three people with real problems that did not show up until they did more tests, even though Mac OS was blindly oblivious to anything being wrong (it was, they upgraded RAM and SO-DIMM was not fully seated in one case, in another the RAM module had to be replaced).
Extended Tests using Apple Hardware Test is not conclusve and almost never ever when comes to finding gpu or memory 'errors.' There you are better with Windows test utility.

Is a WD My Book Studio Desktop 3TB Hard Drive - FW 400/800, USB 2.0, Apple Time Machine Ready external hard drive bootable with my Powerbook G4 12" PPC 10.5.8?

Sirs or madams,
Is my Powerbook G4 12” PPC 10.5.8 'bootable' with a Western Digital My Book Studio Desktop 3TB Hard Drive - FW 400/800, USB 2.0, Apple Time Machine Ready external hard drive? Western Digital says officially no, but that it MIGHT be. I primarily live in China and bought a datastorage.com.cn Clearlight s400+ external hard drive enclosure with a 320GB disk drive a few years ago in China. My computer 'boots' fine from it, but since I got it in China all the paperwork, etc. is in Chinese; my Chinese isn't quite sufficient enough yet to read it. But there are references to something called "SATA", whatever that is.
My level of computer 'under the hood' knowledge is extremely low. I've been told that SATA has some relationship as to whether or not an external hard drive will boot a computer via the Firewire connection, something relating to 'interface', which I assume is how separate electronic gadgets work, or don't work, with each other.
I frankly don't care much for computers, the internet, or their related gadgets such as all these fancy phones. I longingly reminisce about the days when there were no such things. I use a computer & the internet because I have to, and unfortunately unlike a car where one doesn't have to have 'under the hood' knowledge to operate it, just knowledge of the steering wheel, brake, gas, etc., one seemingly must know a ridiculously great amount of 'under the hood' knowledge, including jargon, to operate computers.
So, please try to respond accordingly; thank you.
If this particular external hard drive won't, for certain, be bootable with my computer, can you advise as to what readily available brand/model would be in the 3TB range for a similar price, roughly $150ish??
Thank you very much.

Mr. BGreg,
Thank you very much. "...under the covers...". I think you meant "under the hood", as in a car. I suppose "under the covers" would be man/woman interfacing, which I am familiar with!
Actually, I'm back in the US now for a few months. I looked at the OWC web site, but only cusorily so far. I'll contact them; they appear knowledgeable about Apple computers.
As to what you wrote about Western Digital's cases, I certainly wouldn't want a poor case. In China I had over time gotten 3 different external drive cases, 3 different Chinese brands, and separately bought Hitachi brand disk drives that 'simply' plugged into the cases. The drives are roughly 80GB 120GB and 320GB. The two larger ones are in cases that have Firewire plugs/jacks, which are bootable with my computer.
So my understanding, as you wrote, has been that my Powerbook will boot from an external hard drive, provided it connects via Firewire, and the disk drive itself is 'normally' formatted with however my computer's own disk drive is formatted, (HFS OS extended (journaled) or some such??). So I was left wondering why Western Digital would indicate that even though their such-and-so external hard drive case/drive was Firewire capable, that they would then say it would not be bootable with my Apple PPC computer......
Well, anyway, since you indicated Western Digital's case quality is suspect, then I'll try OWC and disregard Western Digital.
Naturally, OWC should be able to address this, but your thoughts are also welcome. You mentioned the OWC cases are good with Apples. Would the disk drives OWC supplied with the cases also be of relatively dependable quality?? From my so far only cursory look at their web site they appear to have various options, including case only options where I could insert my own or their own drives. These sorts of options seem preferable, also along with quality components.
My Powerbook has been in use since 2004. In China I put in a 1.25 memory 'chip' in the bottom and installed the 10.5.8 operating system, which I understand are the maximum workable with my Powerbook. When I inquired with Chinese friends if my 1.33 GHz processor could be taken out and a more powerful one put in, they said it wasn't feasible because in my particular computer my processor was, as I recall them saying, soldered/'permanently' connected with the 'motherboard', that it would just be easier to get a new computer.
I would be with them and they would nonchalantly open it completely up showing me all its tightly arranged 'innards' while at least giving it a good internal dust/dirt clean job for cheap lunch and a beer (& so much dirt/dust/lint there was!)...these are the same folks who build the things of course...fast moving hands with tiny screws flying everywhere, but everything 100% all back in place when finished.
My Chinese friends also said that nowadays Apples are not as well built as when my Powerbook was built, that nowadays an Apple's life expectancy was considerably lower, so I fear that when I get a new computer that, though it will be more up-to-date and powerful, etc., it most probably won't last near as long as my Powerbook has. They also said that in an older computer the fan was often the first component to go bad, and if a new one couldn't be easily found, as they said was my case, then you're just left with having to get an entirely new computer. Part of why I dislike electronic computer gadgets generally is that they are obsolete so quickly.
So, anyway, thanks very much for your information.

I am running Snow Leopard on my iMac and have partitioned my hard drive to run Windows XP. If I upgrade to Yosemite, will I still be able to run XP?

...Now what happens if I upgrade to Yosemite on either my iMac or my MBPro?
If I install VM Fusion or Parallels, does Windows run all the time? How does that affect computer performance? and how much do I need to worry about hard drive corruption?
Current versions of Fusion and Parallels are compatible with Yosemite. Both are applications which you only run when you want to run Windows within them. As such, there's no effect on computer performance when they're not in use. Like any other software, there is some additional load on your Mac when both Windows and the Mac OS are running together, but any noticeable effect depends on what each is being expected to do and what resources (e.g. available RAM and the number of CPU cores) you can devote to each.
I think there's less chance of HD corruption with a VM than there is with running Windows natively on the Mac in Boot Camp. Consider that, with a VM, you can create Snapshots of the state of your VM at a given time, and then, if something goes wrong (virus, malware, software installations), you can simply restore the Snapshot in a matter of seconds and eliminate the problems in the process. Moreover you can make a backup copy of the entire VM file, and replace a later version if you wish. Also consider that you can assign, say, 100GB of HD space to the VM, but the actual space devoted to the VM is only what's actually used; as more is needed, more is made available and Windows can't tell the difference. So, for example, my Win 7 Pro VM has an 80 GB virtual HD but only takes up 45 GB on my SSD, and that's with XP Mode in VPC installed inside it.
Microsoft no longer supports XP, though virus signature updates are still being issued. But MS has installed a pop-up message about EOL that won't go away (it's installed with KB2934207). Even if you remove that KB in Add and Remove Software, the pop-up continues. But if you have a Snapshot or a backup which is prior to it's original installation, you can skip installing KB2934207, and suppress it's reappearance on a Software Update list.

3Tb Hard drive and Bootcamp

Hi everyone.
I recently updated my iMac to a 3Tb hard drive, replacing the old one. Restoring MacOSX partition worked like a charm: I booted using moutain lion installer on an SD card and used disk utility to transfer partitions from the ond disk (in a USB external enclosure) to the new one.
I did the same with the bootcamp partition, but it failed miserably, as the partition isn't recognized anymore when pressing ALT at boot time.
I scavenged the whole Web, searching for a solution. I found out that my problem can't be solved, and that both bootcamp and W7 are guilty. I tried using rEFIt (or rEFInd), it led to the same failure.
Interesting fact: new iMacs can be shipped with a 3Tb hard drive...
The question, summing all my disappointment: has someone succeeded where I failed?
Thanks a lot for your help!

I just installed a 3TB hard drive on an early 2008 mac pro and the system doesn't recognize the drive. What now?

I just installed a 3TB hard drive on an early 2008 mac pro and it is not recognized/not visible. What now?

If the drive is correctly installed on to the sled, and the mounting screws are snug, not tight, and the sled is inserted properly so that all the roof-tangs catch as the sled is inserted, failure to show up in Disk Utility means the drive is not useable.
A Bug in 10.8.4 and later precludes Disk Utility ERASE-ing large drives in Internal bays. Use PARTITION only, and create one new partition, GUID partition Map, Mac OS Extended (journaled) Volume.

IMac 27in late 2012 Kernel Panic

Everytime I process photos on camera raw using my iMac, it hangs, white screens, then restarts on me. At first it I never had this issue but when it frequented into 3 panics per work day, I reformatted my iMac and installed only photoshop.
I checked on photoshop and turned off the OpenGL thinking maybe it was a RAM issue, but Claire (my iMac) still panics.
Please help. I need to get work done before I start losing money.

I have posted the same question in the adobe forum and their support has replied quickly saying:
That kernel panic refers to a bug in the OS code.
Applications cannot cause kernel panics, or machines to shutdown, freeze completely, or restart.
Only OS bugs, low level driver bugs, or hardware faults can do that.
please someone help me.

i upgraded my ram with 4 8gb corsair value system.
could that be the cause?
Very likely - their was a thread on here where someone on here was having the exact same problem with Corsair RAM. If I can find it I'll post a link.
If you still have your original RAM, take out the Corsair and put in the original chips. If the crashes stop - voila!
Macsales and Crucial are the often recommended places to buy from - they guarantee their modules will work.

3TB hard drive

I have an interesting problem that I have searched a very long time for and have not yet found an answer..
I have a 3TB WD Elements drive, it works fine, loaded it with about 2.5tb worth of data. Plugged it into my linksys E4200 router as a storage device, found out the router doesn't support 3TB (it only displayed as 746gb on the router). So I safely
removed it from the router, then plugged it into back into my computer. Now it says in windows that it is a 746gb drive. In Disk management it says it is a 3tb hard drive, but windows explorer says it is 746gb. So, I know the router didn't
reformat the drive to 746gb, so what is up with windows only showing it as a 746gb drive?
Ive reinstalled drivers for the drive, updated intel rapid storage, and messed with other random things but have not come up with a solution yet. Any help would be greatly appreciated. I don't want to reformat it because I have so much data on
there it that reformating would be last resort.

@Vegan
Fanatic
You've
listed your rig- v. impressive but I understand nothing - presumably it's UEFI with GPT drives - making them bootable from said drive/s
The discussion in play is MBR - Its limitations and how to deploy excess from 2TB net (2.2TB gross)
If you require one Partition of 3 or 4 TB, then GPT on a MBR BIOS PC will do it, but you cannot Boot from it However, 746GB or 1617GB
excess can be allocated with Seagate DiscWizard/Acronis True Image WD EXTENDED CAPACITY MANAGER, freely available for Seagate, Maxtor, WD Drives -WARNING - Do Not Attempt without FULL BACKUP (On another Physical Drive)
TIP - Your Restored O/S or the one's in situ will only see Extended Partition if DiscWizard/Acronis T.I. WD is installed - installs driver that makes this possible
Useful Tools - WD Mybook USB3 2TB/3TB
Seagate DiscWizard/Acronis True Image WD
BOOT CD (Created from within DiscWizard/ATI) Parttition Mini Tool/Easus Partition manager (Have both, sometimes one will do what the other won't allow)
EasyBCD - essential for MultiBooting inc, Linux
'"that
talks about a freeware, but then you are way off and in bad territory" thus speaks an officianado with many points to his name. The only risk you're taking is by not Backing Up - or Backing up on the Drive you're working on - Software supplied by Seagate
and WD, although free cannot be regarded as 'third party', Storage is their business and is very flexible - clear what you've backed up and where backups are stored
'Today's Third Party Software is tomorrow's Ist Party feature in an O/S'
The
storage released in this way can only used as storage - create partition/s in normal way - NO Booting from this 'Drive' within a physical drive
Let me know, if there's anybody out there that needs an O/S Partition greater than > 2TB
Second point:
'I
have used old machines for NAS use fine. Linux and Windows can both be used.'
My question is were any of the NAS drive/s over 2TB net and did you plug them into a Router, which was
the scenario in play ? And what was the interface between NAS and PC, how fast did Linux and Windows boot from NAS compared to O/S on native SATA drive ?

IMac 27" (late 2012) GTX 680 MX, glitch and artifacts on the screen.

Hello.
I have a one year old iMac 27" (Late 2012) i7, 8Gb RAM, GTX 680MX, 1TB Fusion drive. I was working at the computer and was away for two hours. When I woke my iMac from sleep mode on the screen appeared glitch and artifacts.
http://www.youtube.com/watch?v=-666QJQ51Lk&feature=youtu.be
That could happen? This is a GPU problem? Or software?
I am very sad.
It happened a month later after my 1 year warranty expired.
