Mac Pro :: Backup Hard Drive Decision For Time Machine Only

May 6, 2010

I'd like to add a backup HD to my Mac Pro. Not with the intention of doing a RAID set up, but rather just for Time Machine. The two drives in my line of sight are the...

WD Caviar Green 1T
( http://www.wdc.com/en/products/products.asp?driveid=763 )
and the
Hitachi Desk Star 7K1000.C
( http://www.hitachigst.com/portal/sit...star/7K1000.C/ )

I know there's the Caviar Black, as well,, that has a 5 year warranty as opposed to each of the above's 3 year. But I hear its on the loud side, and since it won't be running much more than every other week I don't see the need for the added performance. But perhaps the 5 year warranty alone is worth it. I'm also aware that the Caviar Green will spin at 54K, and that Hitachi is at 72K. Again, the intent and purpose is to be that of a backup HD.

I have a friend that works in Google's server R&D department that swears by Hitachi (based on their excessive testing standards). But I have no experience with Hitachi. So I'm looking for a few more real world stories on what you all are currently experiencing. My main concern is which will be the least problematic over the long haul. I am not interested in Seagate's, nor Samsung's.

MacBook Pro :: Backup Data On Hard Drive When Time Machine Is Setup On External Drive?

Sep 5, 2014

Basically I have a 750GB hard drive in my Macbook Pro and over 300GB is taken up with 'BackUp' data. This is more than the total of everything I have on the drive other than that. Time Machine has always been setup on an external drive and when searching all files on the Macbook there is nothing for backup files so don't know where it is coming from.

OS X :: External Hard Drive For Time Machine Backup?

Mar 29, 2009

I was thinking of getting an external hard drive for use with Time Machine. On Amazon I found a Seagate 1.5 TB unit for $129. However there is a similar model "for the mac" for $192. I am wondering if the cheaper unit would work, or if the one for 50% has some indispensable feature.

Dec 8, 2014

I am doing a backup prior to my first ever format & reinstall. Time Machine will not allow my use of this external hard drive that I had previously used for a Time Machine backup . Time Machine says, " The backup disk is not in Mac OS Extended ( journaled) Format, which is required." how do I change it to Extended (journaled) Format?

Yes the external hard drive in question is meant for Mac.

OS X :: Restoring Time Machine Backup On Blank Hard Drive

Apr 16, 2010

I have a question about upgrading the harddisk on my unibody macbook (last year's model). I have done a time machine backup and the macbook is running snow leopard. However, I currently don't have the snow leopard DVD with me, only the leopard DVD that came with the macbook. Can I still do the hard disk upgrade? In other words, can I boot with the leopard DVD, and restore back to snow leopard via time machine or do I need the snow leopard dvd?

Hardware :: External Hard Drive - Time Machine Backup - Ended Up Freezing My Mac

Sep 7, 2009

Recently this external hard drive I have spun down right in the middle of a Time Machine backup. It ended up freezing my Mac for a second so I turned it off only to have it come up saying it was corrupt and needed a format. I did that and it seemed to work fine only to see it would never eject (it had nothing on it but it claimed programs were using it) so I was forced again to shut it off without ejecting.

This time I turned it back on and it didn't (and still doesn't) appear for about 15 mins.. now SL says "Can't be read" and when I go to disk utility it just shows the drive (no volumes, everything like partioning and erasing is all greyed out)

OS X Mountain Lion :: Time Machine Won't Exclude Hard Drive From Backup / Grayed Out

Jun 23, 2014

I am backing up my data from my mac book pro for a second time. I plug in my external, and it says it doesn't have enough memory to back up my computer. I have 1 TB hard drive and used about 650 MB for the first back-up. Obviously I don't have enough to back up everything for a second time. I just want to back up the new stuff. When I go to exclude the current external from the new back up, it's grayed out. Do I have to delete the contents of the hard drive and re-back up the entire computer?
