FreeAgent Drive is Read Only on Mac OS X

My husband copied a bunch of stuff on his PC to this new drive, now when I plug it into my Mac, I can only copy stuff from it, not to it. Is there any way to change this?  Can it not work with both a PC and a MAC?
Thanks!!

    I have just bought a new Seagate FreeAgent (1tb) external hard drive, which I want to use mainly to transfer files from my OS X 10.5.6 Mac. It's been formatted for Windows though, I see. Can someone please take me step-by-step through the process of converting this for use with my Mac?
    Many many thanks!

OK, after having read through these responses and having tried some different things, I wanted to post what worked for me, because there seems to be some confusion here. First of all, I took the route of trying the ntfs-3g driver. I downloaded it and looked at the directions for a Mac. I have only had my Mac for a little over a year and working with Fink or whatever was not user friendly, so I looked elsewhere. It turns out that Mac does INDEED do Fat32. As one of the other sites that I read says, it is not really very clearly done, but if you use the Mac disk utility application (it comes with Mac OS - I am using 10.5), then you can reformat the disk. It says "MS-DOS (FAT)" for creating the partition, but if it is a large partition, then it will automatically use FAT-32. So I have just formatted my 1.5 TB Free Agent drive with that and copied a .DOC and .PDF file onto the drive. It works fine on the Mac. Then I take it over to my Windows Vista machine, plug it in, and Windows Vista recognizes it, opens the Doc file in Word, the PDF in Adobe Acrobat, and it sees all of the disk space on the drive (after formatting, it says it is actually a little over 1.3 GB - Western Digital stretches it a bit by calling it 1.5 GB). Anyway, the bottom line is that it seems to work like a charm. One caveat is that apparently formatting such a disk with Windows Vista is limited to 32 GB partitions (see MS docs here - http://technet.microsoft.com/en-us/library/cc766145.aspx). However, that seems to be arbitrary and set by Microsoft and is not a technical limitation of the FAT32 technology. So that is how it worked for me.

Ok, first, the format is NTFS not NTSF. NTFS is the new windows format that replaces FAT32. And no, mac does not use FAT32, that is a windows format, Macs natively use HFS+. This does not mean you can't use the drives though. Macs can write to NTFS, you just need the right driver. I found it here: http://www.ntfs-3g.org/

The disk drive format between Mac and PC are very different. Mac uses FAT32 and PC is NTSF. Mac can only read NTSF. If you want the Mac to read and write the drive you will need to reformat the drive to MAC standard which is Fat32.

Posted on Jan 05, 2008

The OP wants it usable on BOTH PC and Mac.

That would be FAT32 since both operation systems can read and write it.

PC can not read Mac OSX Extended Journaled drives (Native to OSX) so that is not an option.

Mac's can't write to but can read NTFS (Native Window NT/XP/...) so you can at least move data in one direction.

Posted on Sep 07, 2008

You have to create a new partition with the Mac Disk Utility, overwrite the old partition. Start Disk Utility, choose the drive (not the volume!), click options, pick GUID, choose Mac OSX Extended Journaled, enter a name for the volume..click apply and wait a little...done :)

My new seagate go flex hard drive is being read by mac but I cannot do any modification, which includes data transfer!!


Most likely the hard drive is formated as NTFS and you will need to download a 3rd party app in order to write to an NTFS file system in Mac OS X, such as Tuxera NTFS or NTFS For Mac OS X

I have a 230 gb FreeAgent Go external drive.


Hi,

I think the solution that meeknotweak gave is a little bit twisted. First and foremost you can not be able to format a 230gb hard drive as a FAT or even FAT32 simply because that FAT and FAT32 is only set to be used and can be used only if your drive is less than 40gb. If your drive is larger than 40gb then the only option is to format it using NTFS.

Second you can be able to format and set the volume format of the drive under the ERASE tab of the DiscUtility on Mac. Not in "RAID" tab.

This is the right way to do it......

If you plan to use the external HD into a PC or Mac, you should first plug it into a Mac Computer and format it using the Disc Utility. Choose the Erase Tab and select Volume Fomat. Make sure that you choose MS DOS. Only Mac OS can format a drive of any size to a FAT file system. If you have already formatted it you can now be able to use it vice versa.

One more thing if the HD is formatted as NTFS, Mac OS can read it but can't write on the drive. So that's why you need to make it as a FAT so that it would be readable and writable to both OS. Also make sure that the folders and files that you're transferring into the HD doesn't contain special characters. Mac OS can recognize those special characters on a file but windows can't.

I hope this clarifies everything.

I plugged my seagate into my mac OS and backed it up first, then went to my pc running windows xp and tried to locate the seagate drive and couldn't. Can I only use the Seagate on one machine or another?


Hi,

If you are planning to use the Seagate Hard Drive on a PC and MAC better format it on your MAC Computer thru disc Utility and choose MS-DOS. This should solve the problem.

Mac has the ability to recognize a FAT, NTFS and MAC File System for the hard drive but the PC Computer cannot recognize MAC File System.

Check on your mac the File system of your hard drive.
MAC OS Extended
MAC OS Extended (Journaled)

If this is the file system then you now know that it will not be read by PC.

Also formating it with the use of PC will only result in an NTFS File System, and it can be read by Mac but it is only in a Read Only mode. You cannot copy paste or even erase on the drive having an NTFS on a MAC.

Formatting my Freeagent 1tb external hard drive for my Mac?


the problem is that your western digital operates using the NTFS (New Technology File System) which is the standard file system of Windows. Apple macs is not interopable with native NTFS therefore you need to install a read-write NTFS file-system driver on your mac.

an excellent free mac NTFS driver can be found here-
http://mac.softpedia.com/get/System-Utilities/NTFS-3G.shtml

download and install the software then restart your mac.

My Freeagent external hard drive doesn't show up on My Computer


Your Mac would have formatted the Seagate drive as HFS+ (journaled) format. If you have access to a Mac, copy your data off the Seagate to any Mac, then use your PC to reformat the Seagate drive in FAT32 format. Macs recognize FAT32 format, and can store data in it, but can't create the format. The Mac holding your data can store it on the Seagate in the FAT32 format, and you can then copy the files to your PC. Hope this helps.

Seagate Free Agent Drive Cannot be Modified on Mac G5


First of all Hello John :)

The new seagate drive you got needs to be unpartitioned and its file format system needs to be deleted and changed.

NB: You will lose all your data so make sure that you copy everything useful off it before you do these steps.

1. Get hold of a windows PC and right click on my computer
2. Choose manage ... choose disk management right click on the drive and delete the partition type
3. delete again until it comes unpartitioned space
4. Then go to your mac and you should be able to format it as a regular Mac drive.
5. If the Windows PC is inaccessible. Get hold of a copy of Linux UBUNTU distro. Boot your MAC from CD choose to boot os from CD (don't worry it will install nothring on your MAC it will just use the CD but make sure you choose the right option)
6. Keep your hard drive attached so it gets detected during bootup. Once the UBUNTU OS boots choose GParted and from there do the same thing i explained above.

Hope that this was of help :)

Cheers
(please take some time to rate solution)

Configuring FreeAgent for Mac OS


Lesson No. 1 - Never buy hardware or software from a store at which sales staff think the best way to answer your Mac questions is to convince you to buy a PC.  Lesson No. 2 - Reformat the drive using the Mac Disk Utility included with your MacBook after consulting with a store at which the sales staff know there is more to the computer world than PCs.  If you only intend to use the drive on your Mac, choose the option Mac Extended Journaled when rewriting the drive. There is also an formatting option to use the drive on both PC's and Macs. But I'm not going there.

FreeAgent Drive cannot be Modified?


The problem with the compatibility between your external drive and your mac is that freeagent drives are formatted in NTFS and the Mac uses FAT32. Mac's can read from NTFS drives but cannot write to them. I'm afraid that the only solution is to re-format the drive in FAT32 format if you want to be able to write to it.
