Bug Description
I was installing to an external SSD, HP P600 to be specific.
This is an annoying bit of hardware, as it's actually 2 125GB SSDs in a single case, so functions as 2 drives.
The message...
"The partition ... starts at an offset of 3584 bytes from the minimum alignment for this disk, which may lead to very poor performance.
Since you are formatting this partition, you should correct this problem now by realigning the partition, as it will be difficult to change later. To do this, go back to the main partitioning menu, delete the partition, and recreate it in the same position with the same settings. This will cause the partition to start at a point best suited for this disk"
There are 2 options "Go Back" and "Continue".
The issues...
1) Both buttons "Go Back", there is no way to ignore the error and continue. So you need to either only have the "Go Back" button, or truly allow the user to ignore the issue.
2) The advice is incorrect. Recreating the partition does not solve the problem. The problem was with the default partition table on the devices. I have no idea why it was like that, but the resolution was to wipe the partition table, not just recreate the partition without the existing table. This was not trivial to work out, I was messing around trying to find what to do for a while.
