ok, so i've gone and done something a bit daft, as always when i ask for help here on TS. my ever reliable NEC ND6750a DVD drive finally gave up, so in my inifinite wisdom i went to the store and bought something off the shelf which looked like it would do the job (brow becomes furrowed). i bought a Sony Optiarc AD7580a. which now seems a mistake. having read up a bit on the internet it seems that Toshiba laptops don't like 'em that much and mine won't even recognise the drive or power it up so i can even open it. anyways, some people have pointed out that i may need to change the IDE settings with a utility. but the utilities usually point to the drive being an AD-7590a... so, the question is; will that utility work or can anyone recommend another tool or another way to proceed..?? p-l-e-a-s-e-!!
