Old Dell 9300: HD Transfer Speed down to 2.5 MB/sec after some Windows Updates?

This was an old laptop that I kept for my mother to use for her once a blue moon usage. Big screen and convenient.

Off late I had some data on it that I wanted to have so I transferred a bunch through USB to external 2.5" HDD as well as via Ethernet network.

Speeds were 15-18 MBps.

Then while it was on the network it kind of wanted to update the OS with patches. So I let it do that.

The next time I tried a Network or USB Transfer the speeds crawled to 2.5 MBPS.

I figured something was wrong with USB since XP updates.

But today I ran HD Tune and it shows HDD Max & Avg speed at 2.4 Mbps.

What happened? Why is it croaking slow now?

Thanks. That was the issue and no one was able to point it out. I did the WORKAROUND in the article.

I wonder if there is a QuickFix without having to install a full service pack?

If you do like in "Let me fix it myself"
Then when problem is solved,counter is reset so even after more errors once it's fixed counter is reseted and all begins.from 0
Without that counter increase and increase until driver is stuck in PIO mode.
