I have a 500GB Samsung 5400 spin hard drive. I first had it in my 2008 MacBook unibody and then recently moved it to my 13" MacBook Pro. On both machines from time to time I get a new folder in the trash called recovered files. It seems to happen after boot up. What I can't figure is it doesn't do it on the other hard drives. The 13" MacBook Pro's stock drive never did it nor did the Seagate 310GB 7200 spin now in my 15". Does anyone think the drive is bad for some reason? Thanks
