Pre-formatted hard drive only

I have seen in shops that you deserve to buy outside Hard drives in both Windows and Mac format.

You watching: Pre-formatted hard drive only

I was under the impression that an outside Hard drive will work throughout both platforms, but having seen this and also the fact that the Mac formatted one was £20 ($32) more expensive for the exact same capacity. I wanted to recognize what the distinction is and what the benefits of a pre-formatted hard drive were.

It"s more than likely no various hardware-wise, simply currently formatted for the Mac. There"s a totality pile of people that still think Macs require special everything, so the providers take benefit of that to fleece them out of an extra £20.

In general, you do not need one-of-a-kind Mac-just hardware stuff anyeven more. Hard drives, RAM, peripherals, and so on are all fairly mostly universally compatible; even the stuff that"s primarily seen as "Mac" (i.e., FireWire and also currently Thunderbolt) is Windows- and also Linux-compatible and also will certainly primarily work-related fine.

EDIT: I guess I deserve to think of one good reason to buy a pre-formatted "Mac" drive: if the user is not someone who is comfortable formatting disks. On the other hand also, Disk Utility is sufficiently straightforward I"ve walked my parental fees via formatting drives a couple of times over the phone, so I wouldn"t waste the money.

This is most likely the instance 99% of the time. External tough drive compatibility rests largely on the file device (HFS+ for Mac, NTFS for Windows, EXT3 for Linux, etc.). Cross compatibility rests on the OS itself (and also extra plugins). But occasionally, the devices themselves, which carry proprietary firmware for the controller, might vary. Some WD external systems don't play nice via OS X power settings (Mac's use the pmcollection energy to set points prefer HD spindown and sleep time). So while it might be just a case of petty "fleecing," it doesn't hurt to hit up Google and also double examine compatibility. –user10355 Mar 19 "12 at 23:13

Tright here is no advantage to purchasing a Macintosh formatted drive bereason it is trivial to reformat the drive yourself utilizing Disk Utility.

Open Disk Utility.

Select your new disk from the panel on the left. Select the disk, notthe partition which appears listed below it.

Click on the Partition tab on the ideal.

Important if you arrangement to use this as a bootable drive, choose Options… (under the Partition Layout section) and select a GUID partition map (assuming you"re using Intel based Macs.)

Select the Format which is Mac OS Extended (Journaled) unlessyou know the specific factor why you"re utilizing something else. I would certainly also leave the drive as a solitary partition unmuch less you have a clear concept about why you"re not doing so.

Click on Apply.

None to any kind of user that knows just how to format it via Disk Utility. Its just a marketing technique to justify a slightly better expense. Now if you setup to plug it right into a Airport Extreme as a outside hard drive and don"t have a Mac in the residence to format it, then it has worth.

It is exciting to note that Hard Drive Manufacturers use the correct meaning of "Gigabytes" when referring to difficult drives, and also not what a lot of world think of as a GB which is actually a Gibibyte:

Gigabyte = 10 to the 9 bytes = 1000000000bytes = 1000 megabytes

Gibibyte = 2 to the 30 bytes = 1073741824bytes = 1024 mebibytes

Due to the fact that Mac OS X additionally switched to this "proper" definition for storage systems such as Gigabytes as of Snow Leopard, then the dimension of the drive as stated on the box is more likely to be precise once formatted for a Mac Partition than for a Windows Partition wbelow your usable room seems "lower".

Keep in mind that all this is simply so a lot technical drivel, your actual area easily accessible is the exact same on both, it"s simply that from a marketing perspective the given dimension will be correct on Mac as they have actually a common knowledge of what a Gigabyte is, and incorrect on Windows which supplies the generally missupplied Gibibyte structure on it"s filesystems whilst customers mistakenly assume it is steps in Gigabytes.

Technically manufacturers should usage GiB not GB once marketting and also packaging their drives, however they don"t/won"t, and also usage Gigabyte which they know nearly everyone offers incorrectly.

So, to make this a valid answer, the advantage is to know accurately the dimension of the drive you bought, and not have actually it magically shrink when you use it.
