I have been having numerous problems with my ST251-1 hard drive almost the
enitre time I've owned it.  Errors seem to crop up daily with my files,
making them useless.  Norton Utilities finds about 5 errors a day. 

After reformatting the drive all errors were gone until I copied more files
to it.  After looking more carefully,  it appears that unused sectors of
the disk never have errors.  

I suspect that the reason only used sectors are damaged is due to heat 
problems.   Can anyone confirm this?

I have installed the drive in a relatively small computer (Epson Apex) without
it's own power supply.  Could it be that it also needs it's own supply?

BTW, I was having similar problems when I bought an ST251 last August,
	and Hard Drives Internat'l replaced it no problem.  Since this 
	problem is still occuring, I assume that the drives were both 
	physically OK.
