    4GB Not Suitable for Time Machine

    • Written by from Sioux falls

    These drives spin down when not active, even when you have System Preferencs set to not let that happen. This causes a problem with both Spotlight and Time Machine. The first Time Machine backup works fine, but the second fails because the drive doesn't spin up before Time Machine times out on it. And more backups always fail because Spotlight has hung on the device at the same time. You have to reboot to clear this.

    I contacted G-Technology and they told me to buy software that keeps the drive spinning by constantly using it, even when it isn't needed. There is no settings or jumpers you can change to resolve this. There are a couple of posts on the Apple Support Forums that discuss this as well.

    I give it three stars because its an otherwise usable drive for normal use when you're sitting at the machine. But don't buy this if all you want it to do it Time Machine backups.

    I purchased this hard drive about 3 months ago now, i have used alot of external hardrives over the years, and have always been partial to LaCie D2 series, but as more and more of them began dieing, i decided to drive another brand...This G-Technology Drive not only looks great beside my imac, with the impressive 4tb of space and its very small footprint, this thing has been flawless! I have kept it running constantly for three months straight, as i use it connected to my airport extreme as a network media server...it stays cool, has never froze, the fan is quiet, i cannot find a single flaw with this drive..i will definately be buying more to replace my aging LaCie drives!

    What a fantastic external hard drive!

    • Written by from Workington

    I purchased this external hard drive to use with my 2012 iMac for Time Machine.

    The G-Technology drive can connect by either Firewire or USB 3 (I use the USB 3 connection).

    Before I set it up for Time Machine I wanted to see how much faster USB 3 was to USB 2. So what I did was, I had a 3.96 GB folder which contained some video's. I firstly copied this folder from my iMac to my USB 2 external hard drive and the total time took to copy was 1 minute 49 seconds.

    I then copied the same folder to the G-Technology drive and it took just 24 seconds. I knew USB 3 would be faster than USB 2 but not that much faster.

    For Time Machine this drive is perfect, it has masses of storage and with USB 3 speeds, Time Machine backups are done in seconds. I tend to do a Time Machine backup once a day, and with me installing a fair amount of my stuff (due to just receiving my iMac) the backups are in the region of 10-15GB. This drive completes these 10-15GB backups in around 30 seconds over USB 3.

    I find the drive to be relatively quiet although not as quiet as the iMac, but that's only to be expected as this external hard drive is on the outside and not on the inside like the iMac's hard drive is.

    The build quality and materials used are superb. Its made of aluminium and is an exact match for the iMac or Macbook's. The hard drive is very solidly built.

    For me, this drive ticks all the boxes. Its fast, very well made, the design is a perfect compliment to the iMac or Macbooks.

    I cannot recommend this drive enough.

    I would prefer silence...

    • Written by from Port Moody

    I decided to upgrade from a WD My Passport (1 Gig) and opted for this because it has 4 Gig and a firewire port, which is the fastest possible connection to my 2009 Mac.
    The downside of the G is the noise of the fan. It isn't as loud as say, a PC Fan, but it is by far the loudest part of my system.

    If you are an audiophile or have a small home studio for recording, you will likely find yourself turning it off so the fan doesn't engage while you work on projects or even listen to music. It is really disappointing, since it is so highly engineered.

    There is also a bright white light that flashes when the drive is engaging. It turns my room into a disco if all the lights are off.

    I'll keep it because I have faith that it is more reliable than other products because of its robust construction, and hope the little extra noise is worth it.

    G Drive 4TB drive

    • Written by from Bristol

    These drives are terrible. I will be returning this drive shortly to the Apple store where I bought it. Despite disk util saying nothing is wrong, it hangs FCP all the time, can no,t and randomly decides when it can be unmounted, spins down way to much causing problems and is is way too slow. Can not be daisy chained even with only one other FW800 drive (from a MacPro fully pimped out) tonnes of errors there that require rebooting in most cases. Very disappointed with this drive. When G Tech first came out they were good but their QC is terrible now. Previously I returned a GRaid 2TB as it had mechanical failures withing 2 weeks of operation. NOT good if you are making a living from being an editor. Who to trust?

    Not Good

    • Written by from Gerrards Cross

    Umm... firstly as stated before by a number of people, these drives are noisy, spin up and down randomly and blink away in the evening in a way I can only assume is to warn off ships from the rocks.

    Aside from all that though, they seem to have a finite life of around 12 to 18 months and then fail. I have had three of theses, 2 x 2TB and a 4TB for Time Machine. I have had all of them fail within the above timeframe which is appalling considering the price.

    Switching to something else because protecting my data is important to me and I do not trust these drives any more.

    Lots of potential; poor implementation

    • Written by from Etobicoke

    First I'll tell you that i'm on my second one of these. The first one got bricked when I updated the firmware as per their tech support.

    This drive looks really nice and its built out of really nice materials. So before you plug it in; you'd think its pretty good so far.... But then once you start using it; you'll notice that it ISN'T full copyable with Time Machine. The drive goes to sleep and takes too long to wake up and by that time; TM has timed out and that particular backup will fail and fail and fail until you unmount the device, turn it off and on and it remounts. TM will work a few times after than and then it'll go back to not working with TM.

    My latest misfortune with this device is that I went to plug it in via USB3 instead of FW and on 2 different Macs it says the drive isn't recognizable and needs to be initialized. Even on the same computer with FW it will work; but not USB.

    Definitely sloppy sloppy implementation on the hardware software side mar an otherwise nice drive

    Do not buy

    • Written by from Montreal

    The G-Technology 4GB and 2TB drives are not worth the money. I have been using them for over 6 months now and always have constant "Disk not Ejected Properly" messages whenever I have to transfer medium to large size files. Even worse this happens when using Time Machine Backup, making these drives completely unreliable.

    To be fair I do not know if the problem is with these drives or with all Firewire drives. I have tried these drives on 2 other macs and experience the same problems.

    To use these drives at all I have to copy files in small batches and then watch until the copy process sends without errors to know for sure that the transfer was successful. 50% of the time an error pops up forcing me to restart the process again. Total waste of time.

    The Apple Time Capsules (Apple Routers with built-in hard drives), while slower in my experience, work much better.

    The best possible solution for storage is internal drives. This is an expensive option on iMacs but a cheap and DIY project for Mac Pro's.

    Too noisy, too slow, too unreliable.

    • Written by from Reading

    The noise from this drive would probably be fine for a working environment but it's too loud for the living room unless you have a suitable cabinet. It's about the same volume as my MacBook Pro when the optical drive is spinning and the fan is on full.

    I've been trying to put my iTunes library on the drive and so far it comes to around 1.5 TB - and I've just spent the last 20 mins waiting for the drive to accept one new piece of album art (via Airport Extreme USB). It seems to fall asleep, takes a while to wake up and then gets quite confused - endless spinning ball followed by jerky response.

    The first time i used this drive (Airport Extreme USB) it unmounted and Disk Utility said it needed repair. Since then it's unmounted four times in a week but hasn't needed further repair.

    Why two stars? Because this is the third drive I've bought and every list of reviews I've seen seems to have at least one tale of woe like this. I'm starting to think it's just a matter of pot luck - and this drive may be as good a gamble as any.

    G-Technology 4TB G-Drive Falls Asleep all the time

    • Written by from Beaverton

    Even when told not to sleep by Mac OS X Mavericks, both my 4-TB G-Drives always fall asleep after just a few minutes. This makes working on multitrack recording using these drives extremely tedious and annoying. They need to respect the system sleep settings and stop snoozing on the job! They should also still fall asleep as expected when the system sleeps.

    This falling asleep "Feature" makes these drives lose all the praise any of their other features would warrant. They become targets for replacement with a better product.

    Also, there is no mention of this in their support documentation. I know this is an issue for even earlier versions of their products. Their complete lack of acknowledgement and failure to address this issue makes me want to work with a different company next time too.

    This drive is not Mac compatible

    • Written by from Warrandyte

    The hdd spins down and is too slow to spin back up again. Therefore unsuitable for iTunes library or Time Machine. If forced to service this type of application the file system gets "confused". The impact is that while you can read from the drive, you can't create new directories, save to it or eject it, because it is still being "accessed" by processes long since terminated. The only way to clear the issue is to restart the Mac.

    There are so many other drives that work perfectly fine. This one is not recommended!

    A quality component...

    • Written by from Liverpool

    ... with room for a little improvement.

    It looks great, is solidly built and was put straight to work with no fuss at all - I'm running it via firewire 800 and it transfers my files at a fair old pace.

    However, it doesn't have the quietest of fans (not loud especially, but not particularly quiet either) and the ultra bright, blinking LED has proven to be a real distraction (in my low-key office). Sadly, I've had to relocate away from my desk to save it distracting during photo-editing - which is a shame really, as it did look good next to my iMac.

    For build quality, ease of use, looks and speed it is easily recommended - just wish I could turn off that blinking LED!

    Fast and reliable

    • Written by from Lisburn

    I bought this drive a few months ago and have found it reliable, quiet and fast. I haven't quite managed to work out the best way to connect the drive to my Mac i.e. whether Thunderbolt is faster than USB3 as I have been impressed with transfer with both. The drive also looks great beside my MBP. It comes complete with Thunderbolt cable which is another plus!

    I wouldn't say it is perfect but it is darn good

    • Written by from Roseville

    I use it as a network drive via USB 2.0 cable plugged into the back of my router. It does spin down when not used so there is a typical delay upon wake up. It is quiet and stays cool even with continuous use. I have several hundred ripped DVD movies stored on it and I stream them via Apple TV and it works flawless for this, I also use it for Time Capsule and it also works flawless in that application.

    Why 4 stars and not 5? The wake up could be smoother.

    Does not work with Time Machine

    • Written by from Maidstone

    I decided to invest in a new external drive specifically for Time Machine. Instead of sticking to my standard Western Digital drives I decided to look for something different and saw the G-Technology drives in the Apple Store.

    These drives are very solidly made and the design is really sleek and impressive, much better than the standard WD black boxes (but a lot more expensive also). The only trouble is they don't work with Time Machine. There is a known issue (allegedly related to file permissions) that results Time Machine 'write errors'.

    Various workarounds (swapping the drive, upgrading the firmware) do not work but switching to USB did (it seems there may be a known Firewire problem). Only problem is this may not be a good fix for older Macs running USB 2.0.

    G-Technology are saying its a known Apple problem (Time Machine). The Apple Store still states "Plus it's plug and play on Mac OSX and ready to use with Time Machine". So beware, you are unlikely to get a refund because G-Technology say the drive is not faulty or because you swapped the drive for a later model in the hope it may work.

    Nice looking drive though. Oh, and it is noisy.....

    Not Suitable for Time Machine

    • Written by from READING

    I would agree with previous comments, this drive is not suitable for use with Time Machine, fails after a couple of back-ups, you then have to restart your Mac to enable it again. Have trawled the FAQ's & posts for work-a-rounds, but to no avail. Apple should take this unit off their site as it misleads people into thinking it will be compatible with Mac OS, specifically Time Machine!.
