Error message when checking external drive before full disk encryption on Mac

This issue has been solved. See solution.

Hi,

I'm new to PGP. I want to use WDE for the first time on an external drive connected via USB with my Mac. In the process of checking the drive, I'm translating from German now, I get the error message that a problem has occurred when testing the drive and that there may possibly exist a problem with the partitions of the drive. I formatted the drive with Mac OS Extended (Journaled). Can somebody, please, help me?

Make sure it's a GUID (GPT) partition, and not an Apple Partition or MBR.

 

Caution:  Changing partition types wipes all data from the disk.

Hi,

Thanks. I should have mentioned it but the drive was already partitioned in GUID, and I still got the error message. I had looked this up in this forum before I posted. It's an Iomega eGo which is made by EMC, I believe.  I tried a Seagate drive, and it seemed to have worked, but I have a question on how long it takes to encrypt an empty drive, please. Both are drives that I erased first and then partitioned. I did interrupt the erasing process on the Iomega drive half way through, though. I was overwriting it seven times with zeros, and I stopped the process after the fifth turn or so. That may have something to do with it. I'm erasing it again once now and will go through the whole process again. See what happens. Maybe that drive does not work with PGP?

My question on the  Seagate drive is the following, please: the process seems to be working as I get directed to use either a keypair or a passphrase. I choose passphrase. It checks the quality of the passphrase showing me the strength of it in a bar. I select proceed. Again, I'm translating from German here. A new window opens that shows me zero progress has been made on encrypting the drive. I choose forward or proceed with encryption. The Mac Rainbow ball turns for a few seconds, it shows zero progress on the encryption. I do it a few times. Same thing. I unmount the drive. When I mount it, it asks me for the passphrase. So my question is: Is the drive now encrypted? Shouldn't the encryption process take much longer and why is it showing me zero progress has been made on the encryption. Again, the drive was erased and then partitioned. I want to make a bootable clone using CCC, and I think it was settled on the PGP forum that one should encrypt the external drive first and then make a clone. Thanks.

Just realized that the Iomega has one of those annoying virtual partitions that cannot be removed.

Hi,

I'm sorry to have posted so often, but the Seagate drive is being encrypted right now. I went to file -> decrypt/verify (again translating from the German version), chose the drive in the finder window, clicked on the button decrypt/verify, it asked me for the passphrase, and I ended up where it showed zero encryption and continue. I chose continue and it started encrypting the drive. So this topic has been resolved. Thanks to everyone that looked at it.

Cheers,
