Copy Error 0 - Can't copy .img file to external drive

I am getting "Copy Error 0" when I attempt to copy an 8 GB .img file to an external drive.

The .img file has been dismounted, and no applications are using it (I have re-booted).

I have copied files this large to this disk before, but never with a Mac (my iMac is new). There is still plenty of space on the disk.

Is this a file permissions problem? I can't seem to figure out why this does not work.

Thanks for any help.

iMac 3.06 GHz, Mac OS X (10.5.5)

Hi,

to what was the external HD connected before you got your Mac ?
To a Windows PC ?

If so, open Disk Utility, click on the external HD in the left pane and check what file system the external HD uses.

If it is NTFS then OSX can not write to it without the help of either NTFS-3G http://www.ntfs-3g.org/ or Paragons NTFS for OSX http://www.paragon-software.com/home/ntfs-mac/

Hi mcphja2

Both Mac's and PC's can read and write to FAT32, but have a *single file* size limitation of 4GB.

Note: With the OS X Disk Utility you can reformat the drive Mac OS Extended (Journaled) to handle larger files, but it will "erase" the current data and make the drive unusable on a windows system!

Hi,

if it is FAT32 then you are encountering the single file size limitation of FAT32 which is 4GB (or slightly lower than 4GB).

If you can't reformat the external HD to HFS+ (the OSX file system) or NTFS, your only choice is to split big files into smaller ones using something like SimplyRAR http://www.macupdate.com/info.php/id/21430/simplyrar

Hi Leberger Jacob,

the only PC format that accepts +4GB files is NTFS.

To access a Mac formated drive in Windows your only choice is MacDrive http://www.mediafour.com/products/macdrive/ which seems to have problems running with Vista 64-bit.

To access an NTFS formated drive fully from OSX you can use either NTFS-3G http://www.ntfs-3g.org/ or Paragons NTFS for OSX http://www.paragon-software.com/home/ntfs-mac/
