Blind Writes is when the computer writes data to the drive without a read verification. This is good if you want something done fast but it can come with mistakes if the media is iffy. Personally I do not use Blind Writes. It can cause problems.

Furthering, with a heated discussion about OS9 and SSD (including CFs as an SSD), your partitions should be under, not over 2GB.  This is because you're using System 7, and a '030 CPU. This creates limitations as to how big partitions should be.

So just try again, but with smaller partitions. I say between 1.75GB and 1.9GB. If you do 1.5GB partitions, you would get two 1.5GB partitions and one 1GB partitions for 3 little hard drives.
