Hi X4Uers!! Got a major panicked kernel, both on OS X and when I went into single user mode (command-s [panic: we are hanging here]). So installed OS X Panther on another drive and transferred users, etc. over (from googling) and everything seems to be working OK. But when I did an Applejack thing, got this message: Warning: ATA drive claims FLUSH CACHE EXT feature support but does not claim Extended LBA feature support. Is there any way I can fix that? It kept on saying disk0s6 i/o error too. That disk, according to system profiler, is the disk I have the new panther installed onto and is the startup disk. When I went to disk utility the smart drive status is verified on all of the drives. Any help would be greatly appreciated. Deb in Rhode Island
