I prefer IBM. I like how it runs ( it's speed ). Had WD drives, two died on me before, one recently, had an old Seagate drive ( 4GB ) that killed itself also . Right now I'm just sticking with what works. IBM.
A big number of the IBM 60GXP and 75GXP had major technical problems due to their construction. IBM lost alot on them. But with 120GXP (and forward) it has been fixed. I have a 120GXP and it has been the best Hdd so far, fast seek time and it is rock steady.
in my dell, i'm on my 3rd drive (a WD) i was never really sure what the other two were, but they both failed on me, but i didn't know so much about computers then, it probably was some sort of **** up on my part and the part of 98SE/Me. but my 40G WD has been going strong for at least a year now.
