External hard drive for time machine back-ups

Can anyone please suggest the best external hard drive to use for time machine back-ups on my iMac?
I also use a 1TB external hard drive for my iTunes library, but I've noticed that it can be slower to access the music than if I used the iMac hard drive......any suggestions? My iTunes library is currently sitting at around 200GB.
Thanks.
Brian

i'd recommend a firewire 800 drive. many folks here speak highly of drives supplied by [OWC|http://eshop.macsales.com/shop/firewire> and [LaCie|http://www.lacie.com/us/products/product.htm?pid=11156].

Porsche Design External Hard Drive for Time Machine back-up

This is what I am looking to buy for my back up: http://www.amazon.com/LaCie-Porsche-Design-External-9000296/dp/B008SA69L8/ref=sr _1_10?s=electronics&ie=UTF8&qid=1393398362&sr=1-10&keywords=porsche+design.
But this is not available on online Apple Store. Only "desktop drives" are available. What is the difference between "desktop drive" and "external drive?"
Also, how do these Porsche Design hard drives rank in terms of reliability and longevity?
Do I need to install LaCie software to use this hard drive for back-up? Or is it possible to directly use Time Machine to use this hard drive for back-up?
Lastly, how does password protection work? Does the LaCie software have to be installed to take advantage of this?

How about 3.5" Seagate drives? Are they any better in terms of quality?
Currently the promotional price for 3.0 TB Porsche Design "external drive" is $129 (normally $169). Is this a good deal? And the 3 TB "desktop drive" is $153. Why would they sell thr same product under 2 different names and with different prices? What does "external drive" offer for $16 more? As far I know, they look the same...
How about 3.5" Seagate drives?
Absolutely not, no.
All HD can and do crash and fail, its just statistical sampling in total (see graph above)
If you want the most reliable 3.5" HD, get a 2TB Toshiba, which is actually made by Hitachi (confused yet?)
Hitachi sold their 3.5" division to Toshiba (forced to actually), so a Toshiba 3.5" is really a very well built reliable Hitachi 3.5"
On sale, 2TB Toshiba 3.5" (really Hitachi made) only $88

There is actually a non-commercial HD more reliable than this, which is the WD "black" drives, the server grade drives, but theyre not consumer grade
theyre very expensive, and made for server farms.

As said no such thing as Porsche, its Seagate . Porsche is just the name on the enclosure.
Why sell under 2 diff. names?   Actually they do it under 5 DIFFERENT NAMES , Hitachi does the same, so does WD
As I said, there are only 4 HD makers on earth.    The many names etc is to fill up shelf space with diff. names such as Porsche , LaCie etc etc.
Id avoid most of the 3TB and certainly the 4TB drives for at least maybe another half year or so.
Large external hard drives are great! Large external hard drives are horrible
It is a common premise that people are overjoyed at the dropping prices per terabyte on external hard drives, and the first thing that enters most peoples minds is "great, I can put all my stuff on one drive,... all of it!" However considerations need to be made in creating a giant single choke point for not mere data loss, but seriously large data loss. If there is at the very least yet another redundant copy, this is fine, otherwise do not consider it whatsoever. Some 3TB and 4TB drives of all mfg. have, at the time of this writing, reliability concerns currently and best recommendation is staying at 2TB drives or less.
Advantages and disadvantages of larger 3TB and 4TB external drives must be weighed
Hard Drive Warning (all makes and models)
Ironically but logical, new hard drives are far more fragile than one that has been working for several months or a couple years. So beware in your thinking that a new hard drive translates into “extremely reliable”!
Hard drives suffer from high rates of what has been termed "infant mortality". Essentially this means new drives have their highest likelihood of failing in the first few months of usage. This is because of very minor manufacturing defects or HD platter balancing, or head and armature geometry being less than perfect; and this is not immediately obvious and can quickly manifest itself once the drive is put to work.
Hard drives that survive the first few months of use without failing are likely to remain healthy for a number of years.
Generally HD are highly prone to death or corruption for a few months, then work fine for a few years, then spike in mortality starting at 3-4 years and certainly should be considered end-of-life at 5-7+ years even if still working well. Drives written to once and stored away have the highest risk of data corruption due to not being read/written to on a regular basis. Rotate older working HD into low-risk use.
The implication of this is that you should not trust a new hard drive completely (really never completely!) until it has been working perfectly for several months.
Given the second law of thermodynamics, any and all current mfg. HD will, under perfect storage conditions tend themselves to depolarization and a point will be reached, even if the HD mechanism is perfect, that the ferromagnetic read/write surface of the platter inside the HD will entropy to the point of no viable return for data extraction. HD life varies, but barring mechanical failure, 3-8 years typically.
Hard drive failure and handling
The air cushion of air between the platter surface and the head is microscopic, as small as 3 nanometers, meaning bumps, jarring while in operation can cause head crash, scraping off magnetic particles causing internal havoc to the write surface and throwing particles thru the hard drive.
Hard drives are fragile in general, regardless, ... in specific while running hard drives are extremely fragile.
PDF: Bare hard drive handling generic instructions
hard drive moving parts
Some of the common reasons for hard drives to fail:
Infant mortality (due to mfg. defect / build tolerances)
Bad parking   (head impact)
Sudden impact   (hard drive jarred during operation, heads can bounce)
Electrical surge   (fries the controller board, possibly also causing heads to write the wrong data)
Bearing / Motor failure   (spindle bearings or motors wear during any and all use, eventually leading to HD failure)
Board failure   (controller board failure on bottom of HD)
Bad Sectors   (magnetic areas of the platter may become faulty)
General hard drive failure

My external hard drive is 'seen' by my iMac and I can go into the Finder and open files and folders. I am using the hard drive for Time Machine back up. However Time Machine says it can't find the drive. Same thing has happened with Final Cut Express.

My new LaCie external hard drive is 'seen' by my iMac and I can go into the Finder and open files and folders. I am using the hard drive for Time Machine back up. However Time Machine says it can't find the drive.
The same thing happened recently between Final Cut Express and my other LaCie external hard drive used as the Scratch disk. It fixed itself.
I've run out of ideas. Help would be very much appreciated. Thanks.

have you done some searches on FCPx and time machine? Is there a known issue with using a TM drive with FCPx? dunno but ...wait...I'll take 60 sec for you cause I'm just that kind of guy.... google...." fcpx time machine problem" Frist page link
http://www.premiumbeat.com/blog/fcpx-bug-best-practices-for-using-external-hard- drives-and-final-cut-pro-x/
You cannot have time machine backups on your hard drive if you intend to use it in FCPX.
booya!

I have just upgraded from a Macbook to a Macbook Air. I have been using a iomega external hard drive for Time Machine, which use a Firewire. However, Macbook Air's do not have a Firewire port and i cannot find an adaptor anywhere. Can anyone help?? Thanks

There has never been a reliable firewire ---> USB adapter suitable for external high speed storage. This was a major issue when the MacBooks lost the firewire port a number of years ago (Apple subsequently brought it back).
The only high speed port on the Air is the ThunderBolt port. There are external ThunderBolt drive options out there, but they're somewhat more expensive than traditional USB/FireWire options.

HT201250 new external hard drive for Time Machine backup suggestions?

Ok, I have 3 external hard drives; unfortunately I've used them on my PC and they are read only on my iMac. So, I need to buy a new external hard drive for Time Machine backup. I'm a little confused; can I buy any EHD and them format it so Mac can use it or are there special EHD's I need to purchase?
Anyone have a particular EHD that is working well for you? Thanks, Blue

Unless you need all three external drives for your PC, you can reformat in one of them in Mac OS Extended (Journaled) for use with Time Machine. However, since Time Machine backs up hourly, you'd need the external drive to be running constantly. That means ventilation of the drive becomes an issue since some, such as Seagate, can get very hot in their sealed enclosures. Some drive manufacturers try to get around this by spinning down the drive when not in use, but I've read complaints that that doesn't play well with a Mac. So whether you reuse one of your current externals or get a new one, it's a good idea to keep the drive's ventilation in mind.

Mac mini as an external hard drive for time machine??

I have a mac mini from a few years ago and it is never used. I was wonder if it could be used as an external hard drive for time machine. If this can be done how do I go about setting it up for this type of useage?

Thanks for starting this thread. I too am trying to use my old mac mini in target mode to utilize it's hard drive for Time Machine.
I hope to strip it down to just it's OS (10.5) and use the remaining hard drive space for Time Machine backup.
Is it possible to just have it running at certain times for regular back in target mode? Or do I have to keep it on constantly?
I fear having to restart using the "T" command each time. Isn't there a way to just have it sleep and then have the ability to wake it up as I backup or restore?
thanks in advance for any help.

Can not fine external hard drive for time machine sence lion was installed

I can not fine external hard drive for time machine sence lion was installed, it don't reconise it at all.

I have a Mac Mini (late 2009) and I have an iomega 1TB external hard drive connected to my mini via firewire and usb (usb allows me to use the usb ports on the external 1TB drive to daisy chain other devices). Since I installed Lion, my Time Machine and this 1TB drive (and its partitions) is finicky. Sometimes it is mounted and sometimes it is not. This issue has only surfaced post Snow Leopard and in the Lion era. I am not the first to say this but the whole reason I went Mac was b/c of Vista. I am beginning to think that Lion is the new Vista. Sorry for the latter, just venting... b/c this ain't the first issue with Lion.

I am using an external drive in the exact way that you described. You just keep it plugged in to the computer when you want to access the movies and files. In order to put files on it, just go to finder open up the drive under devices and drag and drop files onto the drive. It is just like using a usb drive with a terabyte of space.

I recently purchase macbook air with OS 10.10.2. I want to use my Seagate external backup plus hard drive for time machine back up. How to partition my 1TB Seagate back up plus hard drive for use with mac and windows pc?

Hi All,
I recently purchased 13" Macbook Air with OS 10.10.2. I want to use my 1TB Seagate backup plus external hard drive as time machine and my windows 7 pc. Please suggest a method. Thanks in advance for your reply.

I strongly recommend having an external drive dedicated solely for TimeMachine. You could partition the drive but if something goes wrong you risk losing the data on both partitions. Should you decide to go ahead with splitting the drive for two different uses you’ll need to partition the drive either using the Mac’s built in Disk Utility program or Windows utility. I believe the built in Windows disk utility program will destroy the current partition and erase the data that’s on it - I use a third party Windows disk utility program for partitioning and it allows for non-destructive partitioning but warns to back up data first just in case. Apple’s Disk Utility can do non-destructive partitions but I don’t recall every trying to do a non-destructive partition on a disk originally formatted for Windows using it. Again - back up that data just in case.
Finally, your TimeMachine drive should be at least 1.5 times (I prefer 2 times) the size of the data you expect to be backing up a year or two from now. In other words, if you currently are using 50GB of your computer’s drive but expect to begin purchasing Mac software to replace software on your Windows computer and if you expect to be putting photos, music, and other data on it you might expect that two years from now you’ll have 100GB of stuff on the drive. So a 200GB partition is the smallest size you’d want. TM’s backup scheme keeps multiple copies of data as it changes so the extra room is important for this scheme.

Is it possible to use more than one external hard drive for Time Machine backups?

I want to use two hard drives for Time Machine backups.
Bigger one keep at home and be sure it is safe.
Second one (very small pocket size) keep with me for travels.
I want to backup to both drives to be sure I can restore everywhere and to be sure if something bad happened with my small travel disk I can restore from home backup.
Is there any problem with listed schema? Is it normal for Time Machine to handle backups for different drivers and keep everything consistent and smooth?

I really need some help! I have been using an Iomega NAS 1TB HD for the past year. And I received an error message. I believe I have ran out of memory on this drive.
Then recently in the last couple of months I got a ReadyNAS Duo 2TB with 2TB RAID. Should I switch my back ups to this one and delete the other back up file or keep the old back up image file on the Iomega?
Can I transfer the old image back up to this new ReadyNAS? How do I do this?
I appreciate any help.

Is it not recommended to use a partitioned external hard drive for time machine?

1. i hv a 1 tb seagate back up plus hard disc ..,,i want to make partitions for using it for time machine, mac, and window repectively . is it not recommended to use a partitioned drive for time machine? some where i have red that time machine wont be able to restore data from external partioned hard drive in case internal hard drive crashes.
2. if i use the seagate back up plus 1tb for mac only and use time machine to take backup (roughly 250 GB) , then the rest space i cant use to transfer movies, pictures from a PC
3. how should i best use the seagate back up plus hard drive (not seagate back up plus for mac) in a way that i use it for back up , and to work with both mac and PC?

I use a partitioned external drive for Time Machine as well as other things.
How you partition it is a function of yoru needs.

Need to reformat external hard drive for time machine?

Hello,
We recently purchased an external hard drive for our family iMac after we had to have a new hard drive put in. We picked up a Western Digital 1tb My Book (http://www.wdc.com/en/products/Products.asp?DriveID=725). I set up the external hd with time machine and all was fine for about a month.
An error message of "The backup volume is read only" started appearing. I attempted to repair the disk through these directions http://support.apple.com/kb/HT3275#1 but when I was trying to follow the steps, I think I disconnected the external hd without dismounting it, so now I'd assume I need to reformat the external hd. I can't seem to find instructions on how to do this. Where should I look for reformatting my external hard drive?
Any other tips or suggestions would be greatly appreciated.

Hard Drive Preparation
1. 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. 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.

Using External Hard Drive For Time Machine

Hi. I will be buying a new iMac and plan to use an external hard drive by Lacie for Time Machine backups. I haven't used an external hard drive for this purpose before -- previously I've always used Apple's Time Capsule. So, I don't know if I can leave the Lacie hard drive unejected and powered on even when I've shut the computer down. The Time Capsule never needs ejecting from the desktop and is always on, but I'm not sure if the same can be done with an external hard drive when using it for time machine backups.
So, I just need to know if, when using an external hard drive such as a Lacie for Time Machine backups, I can 1. leave it unejected even when I shut down the computer? and 2. Can I also leave the hard drive powered on even when I shut the computer down? It would be good if I could do this because then it would just always be on and ready for hourly time machine backups without my having to remember to turn it on and the eject it when it's finished for the day.
I'd appreciate any advice or information.
Thanks in advance.
John

What are you referring with "unejected"? You should know that LaCie drives have got three modes: "On" (permanently turned on), "Auto" (when you turn off your computer, your external disk turns off or you unmount it) and "Off". Choose the one you want.

Of course. You can leave the external disk turned on when your Mac is turned off without any problem. In "Auto" mode you won't have to do anything in order to turn it on again

Using Mac mini as External Hard Drive for time machine

I know this can be done but I am not sure how. How can I set up a mac mini as an external hard drive. Can this be used as a drive for time machine?? Any help is appreciated, Thank you.

Personal file sharing (which may require Leopard on the Mini) or by connecting the Mini to your other Mac via Target Disk Mode. I wouldn't recommend that latter, though; too much chance of inadvertently erasing files critical to the operation of the Mini.

External Hard Drive for Time Machine - 2 TB. Can I remove other external drives it was backing up?

I have an external drive dedicated for Time Machine, it's 2 TB. Last year I started backing up computer (500 GB) and one external hard drive that has 500 GB. IAlso, I have another external drive that is 1 TB connected to my computer. I noticed last week that I was hearing that other external drive sounding funny, so I thought I would add it to Time Machine to back up. Now today my Time Machine failed. I tested the drive or verified the drive and all was well. My thought is because I added this drive to Time Machine it failed because of not enough room? Is there a way to remove that other external hard drive and go back to just the computer and the 500 GB?
I did btw out of a panic mode buy the GDrive that has Thunderbolt with 3 TB, yet I can't use Thunderbolt because that plug is used for my monitor, bummer. But, maybe using this new external drive I can back up the 500, the computer and the 1TB. Any thoughts?

When you say the Time Machine failed, do you mean the drive containing the Time Machine backups failed, or what failed was trying to back up the new drive you added? If Time Machine was able to complete the first full backup of the new drive, then adding Time Machine didn't cause the problem, it was a coincidence. If Time Machine runs out of space it just starts deleting the oldest backup. I suppose it might fail on the first Time Machine run after the initial backup if it didn't have space to delete stuff. When you look at the Time Machine drive in the Finder, is it in fact full? If there's plenty of space left on it, it's not clear what the failure was about.
Also, testing and verifying with Disk Utility will spot some problems but not all.

Thunderbolt can be daisy-chained, so if it or other Thunderbolt devices have a pass-through port it might be possible to do all that. But it might be better to return the drive and get a USB 3 drive instead. It would be fast enough, cheaper, and more versatile. For a single hard drive (not a RAID or SSD), Thunderbolt is not really much faster than USB 3.
