<h1>IT Partnership Fasthosts Web Server Slow Disk Drive Issue Now Resolved (22 July 2012)</h1>
<p>
Following shows what happened when disks were reversed after moving to new chassis.<br>
It didn't boot because he had reversed the drives and because there was no mirror. <br>
Mirror had been removed due to testing and poor performance of the disk 1.<br>
Mirror wasn't created correctly by the Fasthosts engineer. System Reserved partition, important for booting, was missed.<br>
It booted when he added a new disk because the BIOS tries to boot from the first disk that isn't completely empty.<br>
This new disk was also 30% slower for writing in the second partition.
