I bought my slim PS2 in August of last year. Two weeks ago while playing some Tekken 5, the game started stuttering on me. I knew that it could've not been the disc because I had just recently bought it brand new. I get up to check the disc anyway but before I got there I heard this horrible grinding noise of doom followed up by a burning smell. I already knew that it wasn't good. I powered off the system and left it alone for about 2 hours. Mind you that I had not been playing for a long peroid of time or anything.
After 2 hours, I turn on the system. No problems so far. I put in a different game and it starts checking, checking, checking and soon after it tells me that there is no data could be found on the disc. I have heard of people having DRE (Disc Read Errors) but I had never heard of it not finding any data on discs. I even tried a CD and DVD and I got the same results. Bottom line was that my PS2 had gone kaput. Afterwards, I sold the broken PS2 to Gamestop for $45 which was more than I was expecting. I think the GS employee made a mistake and she just let it go.
I then proceeded to go to Gamecrazy and get me a refurbished fat PS2 for $100 and for an additional $20 I added a guarantee that if anything happens to my PS2, I can just take it back and get another one. The fat Ps2 that I have now is a SCPH 30001 model and so far it has been working like a charm. It also reminded me how much better the fat PS2 is than the slim PS2. The slim gets pretty warm if you play for more than an hour or so since it doesn't have the nice fan that the fat PS2 has.
Overall I think the old PS2 is better than the slim Ps2. Needless to say, I was dissapointed with the slim PS2, especially since I always take good care of my systems and all. I hope this has helped in some way.
