zip file containing photos with my computers. So I decided to run some tests with a 1.24 GB. Now, I thought okay maybe it’s just a bad drive? But all four of them being bad, purchased from two different sources? I doubt it. Instead, I must hold down the power button until the Mac turns off. Killing the Finder or Force Quitting doesn’t help either.
I can’t even perform a restart, if I do the Mac hangs at a gray screen after trying to log off. I can’t cancel the Copy dialog box, it just says “Stopping” and hangs. The Seagate 5TB drive is seen by my Mac, I can copy files from the drive quickly, but if I try and copy files to the drive after the copy starts everything freezes and the Finder becomes unresponsive. Previously this was not a problem, as my photo drive has over 3TB of data on it currently. Either way, I can no longer correctly write to the Seagate 5TB drives if using a USB 3.0 port. Maybe it was after I upgraded to OS X 10.9, or after a minor Software Update. Somewhere along the line something stopped working. I purchased these while on sale a while back for the sole purpose of using one as a photo drive and one as a video drive, each with a spare drive to use as a cloned backup. However, I also have four Seagate 5TB USB 3.0 Expansion drives. I can read and write to and from across these disks, and my iMac’s internal disks, with no problem. I have a series of Western Digital and other USB 3.0 hard drives which operate at USB 3.0 speeds.
#SEAGATE NTFS DRIVER FOR MAC OS MAC OS#
On my Windows 8.1 PC, the USB 3.0 write and read is fine (if I format the disk to NTFS). The disks are formatted using GUID and Mac OS Ext. They work fine on my Mac using USB 2.0, I can read and write fine.
However, I can read files fine over USB 3.0. If I do the file copy stops at 1%, the Finder freezes and I can’t even reboot. I cannot write to my Seagate 5TB USB 3.0 drives using the USB 3.0 connection on either of my Macs. However, I have a CalDigit Thunderbolt dock which gives me USB 3.0 capability and very fast USB 3.0 transfer speeds for most of my external disks. I have a 2011 iMac (OS X 10.9) which only has a USB 2.0 ports. I’ve been having an odd issue with my Seagate drives and I’ve run out of troubleshooting ideas.
