7173a problem (hangs up when writing)



the problem is, that if it is in dma transfer mode it just cashes files and hangs up, though cd/dvd is still spinning.
i’ve tried changing cables (80pins), software, uninstalling and reinstalling ide drivers, i even tried with other nec drive…went back to shop and they gave me another one, as if that was bad :smiley: but nothing…writes in pio only mode.
any ideas:
cant change firmware, just in case i need to return it back to shop.
