Compatibility Issue for Samsung 850 Pro with LUKS partitions

[gill984]

I've been attempting to open LUKS partitions which I created using cryptsetup in Ubuntu on a Samsung SSD 850 PRO but I've had some issues. I'm on a Windows 7 64 bit laptop. I am using an eSATA cable to connect directly to the laptop, I have also tried using an eSATA to USB 3.0 adapter cable.

I create the LUKS partition in Ubuntu using cryptsetup and then make a fat32 filesystem inside of the LUKS partition. When I attempt to open the partition in Librecrypt, Librecrypt recognizes the partition as being LUKS. When I enter the password and hit OK I get the message "Unable to open container. Please check your keyphrase and settings, and try again."

When I use the exact same process on a USB flashdrive, the process works as expected and I can open the LUKS partition which I create in the exact same way.

Other things I have tried include using the 6.3 alpha executable and using FreeOTFE both of which behave similarly and did not fix my issue.

I was wondering if anyone has had this issue and might know how to fix it, thank you.

I figured out that the issue was due to having too many partitions. If Windows is using up to drive Z, there are no spaces left to mount a LUKS partition. Does anyone know the best workaround for this?

Thanks for reporting this. LC should report the error better.
There are some registry hacks to hide drive letters.
