MacFilter: Disk Utility will not let me restore external hard drive.
January 28, 2014 3:01 PM   Subscribe

When trying to restore a FreeAgent XTreme 1.5TB from a Western Digital source, the following error message occurs: "Restore Failure Could not change the partition type for /dev/disk2s1 -error- 3554"

The Seagate was in NTFS format, has been erased, and partitioned for ExFat-- I have also tried Mac OS Extended. And I use Guild Partition, as directed. Once I select the Seagate for the destination, and press erase, I receive the error 3554 message. Google searches have not supplied an answer specific to my problem, as I have tried a few fixes--which are beyond my grasp of mac functions.

Thank you for your time and consideration in this matter.

Have you run Disk Utility to see if there's problems with the drive itself?

Yes. I have run every utility within the application, including disk repair and verify. And, the drive worked fine before.

A shot in the dark - but are there any further error or diagnostic messages in the console app that might point to the underlying problem?

No, nothing. It will say it is partitioned correctly. Read and write capabilities. It recognizes the exFAt. I forget the exact phrase, but the first aid utility says it is a drive in good working order.

But once I try and copy the drive from another, I get the error message I posted above.

What exact method are you using to copy to that drive?

Restore. And I have also tried drag and drop.

Can you copy just a few of the files to your internal hard drive (that fit within the drive's free space) from the WD drive? If so, then try copying them from there to the Seagate drive.

Also, if you haven't yet contacted Seagate to see if they've got any advice, it might be worth a shot.
