I'm sure I could find the answer to this on Google, but it's 2am and I wanna go to bed. I've just built a 2.6.16 kernel which I need to support my MP3 player. All seems to work fine, except I can't see my 160GB drive. If I reboot to 2.6.15, I can see the drive. I've got 2 IDE hard disks - an 80GB master and 160GB slave. The 160GB drive has all my music on it, so if I use 2.6.15 I can see all the music but can't access the MP3 player, and if I use 2.6.16 I can see the MP3 player but can't copy any music to it! Are there any obvious kernel configuration options for large drives that I might have missed? Thanks Olly
