Sorry, the operation could not be completed because an unexpected error occurred. Error Code -1309

I am using a MacBook Pro Intel Core 2 Duo 2.33GHz/3GB RAM running OS 10.4.11

I am trying to copy large files to this external hard drive
Western Digital Cavier SE WDXC2500JB 250 GB FireWire 400 Hard Drive

1GB files transfer no problem. But when I try to copy larger files that are 4GB and higher, the progress gets to 99% and I encounter this.

“Sorry, the operation could not be completed because an unexpected error occurred. (Error Code -1309)”

I formatted the hard drive to FAT32 and tried again to no avail.

Please help!

FAT32 has a max file size of 4 gig that’s the problem no way around it. Are you trying to use this drive on both Mac and Windows? 




I installed Mac NTFS 3G on my Mac 10.6.5 and it worked. I can read and write big files, more than 4gb to and from it on both my Mac and Windows PC.

Here is the link to download the NTFS driver

After installed this driver, restart the computer is needed before new change to take effect.

Then do the partition and format the drive:

Take the drive an plug it back to the Mac computer.

Note: Re-partition the drive will erase all data. Please back up first.

Go to Disk Utility.

Choose the “Partition”

Under “Options” choose “Master Boot Record”

Under Format " choose “Windows NT Filesystem (NTFS-3G)”

click “Apply” and “Partition”

The drive is now Formatted with Master Boot Record NTFS File system.

It can be read/write from both Mac and PC computers.

Hmm didn’t know that… interesting. Thank you sir!

Wow this seems very promising! :smiley:

Gonna try it out and see if it works!

Yeah I have a Sharp Quattron LED TV that I wanna plug a usb external hd into and the format is FAT32 only.

My other 1TB is formatted as MacOS Journaled so won’t read. And despite the fact that I have FW800 it still would take forever to backup 700GB+ and reformat.:cry:

Mac OS 10.4.11 had problems with it or something and DIsk Utility dosen’t bring up the NTFS 3G option.

Instead you had to do it through Terminal (which **bleep** if you hate computer code stuff)

However I found an alternative to using Terminal which is MacFuse. Just install before you install NTFS 3G.

Plugged in my PC formatted NTFS external drive to my Mac and it just appeared on my Macbook’s desktop - read-write!!!
