nothing changed. from 1.8 blocks to 28.5 blocks its something in the network. like watching paint dry.

At ~26 blocks/hour it'll take ages to finish the last 100k blocks. Your external harddrive and the enclosure interface aren't suitable for this job and setup, quite obviously. I assume that your Bitcoin node blockchain data is also on the same drive? If yes, very likely most of the time is wasted for spinning rust head seeking action. Harddrives are not known for decent IOPS performance compared to even SATA SSDs.

If you changed some Fulcrum setup options, why is it that you don't write what you did? But maybe your external harddrive is such a severe and narrow bottleneck that option tweaking simply doesn't come through much.
