They seemed to have tweaked the firmware of the disks they use to work with the POS ATA controller the Blade 100/150 uses. When my Sun stock drive died, I went thru pure hell trying to find a disk that would work OK. Of 5 40GB drives I tried, only an IBM IC35L040AVVN07 worked (has IC35L040AVVN07-0/VA2OAF0C firmware) works OK (no *_DMA timeouts) at ATA66. -- -- David (obrien@FreeBSD.org)
