I have a V9 PS2 which started showing disc read error, so I got a new ps2 laser a HD7 one, but the ps2 still says DRE. I've got my friend to try it in his ps2 and it works fine. Also my ps2 doesn't spin the disk, it will only spin if you spin it and shut the door quickly, otherwise you shut the door, it comes up reading disc for a sec then dissappears. Why isnt the disc spinning? maybe if i sort this problem out the DRE might be easier to solve. I once sat there for 2 hours getting the disc the spin, then adjusting both white cogs in the ps2, then spinning the disc, adjusting the white cogs and so on. Please help, any help.
