MacBook Pro :: Formatting External Hard Drive - Format Using Extended Or Free Space?

Jul 27, 2010

I just got my new Seagate 640gb external hard drive and am in the process of formatting it on my MBP. However, I am not sure which format to do? My main use for the hard drive is for transferring media files back and forth between my MBP and PC using just one partition on the drive. I already know I'm not supposed to pick 'Mac OS Extended (Journaled)' because I believe that is to use it as a boot drive. So should I pick 'Mac OS Extended' or maybe 'Free Space'?

MacBook Pro :: How To Reformat An External Hard Drive After Time Machine

Feb 18, 2012

I have an external hard drive upon which I put movie files that I view through a Sony box (like the Roku box). I brought my MacBook in for a repair and connected the same external HD and used Time Machine to make a back up. It did reformat it in order to do so, but since the Sony box isn't a pc or mac I didn't think it would make a difference, but now the Sony box won't recognize HD. Is there a way to reformat it on my MacBook so that I can use it on the Sony box again, or do I need to reformat it with a Windows computer? I had no issues when transferring files only and using the Sony box.

OS X :: Changing External Hard Drive From Journaled To Extended?

Feb 21, 2010

I just recently realized that my Seagate external HD is under Mac OS extended (journaled) and not Mac OS extended. I only want to use this device for storage/backup and don't want to run anything off of it. Is there any non-destructive way to change it to just extended? If not, what are some of my alternatives?

OS X :: External Hard Drive Or Reformat Old One?

Jan 18, 2010

On my vista / xp machines, I have several external hard drives, Seagate, WD, HP, and 1 enclosure kit which contains some old internal hard drive.I don't really need all these drives on my VISTA/XP machines, as I'm trying to migrate to MAC.

I mostly use my mac for photos & creating home movies. So backing up the priceless pictures of my kids is critical.Do I really need to buy a MAC based external hard drive? or can i simply reformat one of my old drives to use on my mac. I know macs have their own file system (as pc's have fat32&ntfs).

Will apple time machine work with a generic re-formatted external hard drive.I also notice their are fewer choices for MAC ready external hard drives ...less specials than PC based externals.

I've never done anything but plug a HD in and get right to work. Now that I've got an Apple, I'm a total nervous Nellie.I just got a WD external hard drive that is FAT32. I understand that the Mac can read/write this format. Would you recommend that I change it to HFS+ or should I leave well enough alone?

Hardware :: How To Reformat External Hard Drive From PC To Mac

Apr 28, 2010

I have a SimpleTech external HD that I want to reformat from PC to Mac. I went to disk utilities and selected "erase", but it will not erase the HD so that I can reformat it.

I have since attached it to my PC, but do not know how to erase/reformat on a PC (I'm a Mac user that only uses my PC for running specific programs). How can I erase this hard drive and reformat it?

Jun 29, 2012

I purchased an external hard drive ( a Seagate 2 TB Expansion Desktop Drive) and was told by the MAC rep in the store to perform the following simple task to reformat the disk so I could drag and drop files from my iMAC and store them on the external hard drive: 

1. Go to Disk Utility

2. Choose the External Hard Drive

3. Select Erase

4. Select MAC OS Extended (Journaled)

5. Click on Erase button 

Unfortunately when I do this, I get the following error: Disk erase Failed with Error: File system formatter failed? I have Mac OS X (10.5.8)...

OS X :: Reformat External Hard Drive For Time Machine Methods?

Mar 29, 2009

I have a Western Digital 500gig external hard drive (model wd5000c032) which I'd like to completely reformat to use with my macbook pro and Time Machine (running os 10).As it is now, my mac can only use 147 gigs, and often gives an error message saying it needs additional space to backup. It was previously used on a pc to hold pictures, but I doubt it used anything near 357 gigs for that.

IMac :: Unable To Recognize External Hard Drive / After Reformat

Jul 7, 2010

Yesterday I reformatted my Macintosh hard drive, partitioned it, installed Snow Leopard on one partition and Windows 7 on the other. I installed all the drivers for Windows 7 from the Snow Leopard disc.

When I plug in my 1TB Seagate external hardrive it's not showing up in Snow Leopard or Windows 7. Not even in Disk Utility. I tried plugging the external drive into my Windows laptop and a pop-up comes up saying "USB Device Not Recognised. One of the USB devices attached to this computer has malfunctioned, and Windows does not recognise it." I think that this may just be because it's formatted to Mac OSX?

The hardrive had all of my photos, videos and music on so I hope it's salvageable. I find it hard to believe that the hard drive malfunctioned at the same time I reinstalled the software onto the iMac.

MacBook Air :: Disk Utility Won't Allow To Mount NTFS External Hard Drive

Aug 29, 2014

I've recently converted to the Mac-side:

I'm having difficulty with my external hard-drive, here's the info on that one: 

Disk Utility won't allow me to mount the drive, I've tried using a number of softwares to read it (working under the assumption that it's an NTFS drive), including Tuxera and Paragon. I have too much stored on the hard drive to empty it back onto my old computer, and so I'm not able order to re-format it.

MacBook Pro :: Disk Utility Recovery Of Files After Deleting From External Hard Drive?

Jun 10, 2012

I had downloaded some files to add to an external hard drive, the hard drive was assigned to a pc before adding these files so it wouldn't let me add files from my MacBook.. 

Had a look around online and made some changes (well thats what I thought) and I was able to transfer files form my MacBook onto the external hard drive. 

What I then figured out was that there was nothing left on the hard drive except for the two file sI just transferred.. 

It turns out I deleted everyting without noticing.

The stpes I followed was to go to disk utility then select the hard drive and click erase (not knowing this would erase evrything). 

So now I have two files on my hard drive and no idea how to recover the 'delted' files. 

I tried using Disk Drill, which found the files but then it said I need to buy the full version to recover them. 

I am wondering if there is any free methods to recover these files at all

Info:
MacBook Pro (13-inch Early 2011)

Mac Pro :: External Hard Drive Seen In Disk Utility But Partition Won't Mount?

Sep 2, 2014

I've been running a Toshiba 1TB external drive on my Mac Pro tower and it's been working fine.  But yesterday it wouldn't mount.  I could see the drive in Disc Utility, but the partition wouldn't mount.  I brought it into work where I'm running an iMac and it mounted just fine.  Why would it stop working on one computer (where it was previously fine) yet work okay on another? And how do I get it working on the tower?

Mac Pro, iOS 7.1.2

Applications :: Can't Modify External Hard Drive Partition With Disk Utility

Jan 7, 2011

I have an external 750GB hard drive that I previously formatted as FAT 32 because I wanted to be able to plug it into Windows computers as well. I was not very thoughtful at the beginning and I just created one big 750GB partition. I currently have 450GB used and about 300GB free.

I would like to create a new partition in the free space without losing the data I have in the disk, and format the new partition as Mac OS Extended to use it for Time Machine backups. Presumably Disk Utility can do it, but when I go to the "Partition" tab it says "This partition cannot be modified" and the "+" sign below it is grayed.

Applications :: Disk Utility Won't Format Or Partition External Hard Drive

Apr 18, 2010

The hard drive is a 1TB Western Digital my book I bought it in January I think. I tried to format it to Mac OS Extended (Journaled) when I got it but for some reason every time I try to erase the part thats named disk3s2 or partition the main one it stops a little before half way through. I don't think its the hard drives fault so I called apple about it one day and they helped a little but it didn't work. Thanks in advance if you can help me. Also a few times I waited about seven hours for it while I was at school and when I came home it didn't move.

MacBook Pro :: How To Reformat Hard Drive (OS X 10.7.3)

Feb 16, 2012

How do you reformat a MacBook Pro (OS X 10.7.3) 2011s Hard drive? I already backed up all the files I wanted to save. But since I have the new Macbook pro 2011 (only a few months since I got it) it didn't come with an installation disc, but instead already came with all the applications. I'm wondering how to reformat the hard drive so it wipes out everything and I can start fresh and what would happen to all the applications?

Hardware :: Running Disk Utility - Moving BIG File On External Hard Drive

Dec 23, 2007

Will running the 'repair disk' disk utility on an external drive screw up any of the files on my external hard drive? I only want to run it because I can't transfer a file from my HD to the external...it's a 6 gig video file in quicktime format, and I'm getting 'error 1309', which I understand is related to file size on FAT32 format. I know it's a huge file, but I've moved others to the external that are over 20 gigs with no problems (iMovie projects, etc). Anything I can do to get this file moved to the external?
