I should clarify that at the time of my hard drive crashes, I only had one hard 
drive, so the heat issue to which you refer didnt apply in my case.  The first 
drive failed in February within a week after installation, following carrier 
despatch, and the second in August.  Both were Maxtor.  The slowness to which I 
referred applied to each individual drive and neither was capable of recovery, 
although the second was partitioned and the data on the partition was recovered 
with Norton Ghost, the C: Drive corrupt.

I have a Dell Dimension 8400 with 250 GB HD and double 1024 MB RAM, not low end 
or old.

I note otherwise what you say.
