OK, the hardware should be good and you are using the same driver & 
descriptor as used previously so they also should be good.

If you have accurately described the method for loading the driver & 
descriptor (which seemed to be as individual files) that will be a 
problem. You really need to merge them into one file with execution 
attributes set; for ex.
merge bbfhdisk.dr H0_ST225.dd >hdisk
attr hdisk e pe
load hdisk
iniz /H0

Then try reading the hard drive and report what the results are.
