Yep , good source of info and here is a Quote from a GCR forum member .
Quote : "If your PS2 is giving disk read errors and you have not modded it or
physically abused it phone 1-800-345-7669 and explain the problem to the
Sony rep and they will tell you where to send it for a free fix.You only
have to pay postage to send it to them and if the warranty sticker is gone it doesn't matter.They say it will be fixed in 7 to 10 working days after receiving it.Worked for me, my ps2 works like it was brand new."
