the flash made it give up faster, which is actually an improvement. 
cleaning the drive turned the fan noise down but didn't fix the read 
issues. it just spins. windows. dos. no os at all. same thing. so, i'm 
concluding that the drive is broken.
which means i haven't ruled out the ide on the board.
today,
 i need to get an external sata/ide-->usb thing and some other 
things. i'll be taking a run for old parts (ram for my secondary board 
is like $2/stick, might as well fill it up. it's also time to upgrade to
 usb 2.0, lol, given that usb 3.0 cards have pushed the price down. it's
 useless from a store's perspective. like, $5. and if i can find one for
 cheap enough ($10) i might even upgrade the chip from a pIII 500, 
although the max the board can take is pIII 950.) tomorrow and will grab
 an old ide then.
i mean, that board has maximum specs that are dirt cheap to attain. might as well...
