I have two HD's 1. maxtor 54098u8 (supports UMDA 100) 2. maxtor 91080D5 (supports UDMA 33). Have all bios options set to auto (only other option is disable) MB is soyo 7vca supports UDMA 33/66 modes, and just installed a new 80 pin UDMA IDE cable (supports UDMA 66). My question is with all things considered why is HD 1 only at Ultra DMA Mode 3 and HD 2 at Ultra DMA Mode 1.
Ultra DMA Mode - Cycle Time (nanoseconds) - Maximum Transfer Rate (MB/s) - Defining Standard
Mode 0 240 16.7 ATA/ATAPI-4
Mode 1 160 25.0 ATA/ATAPI-4
Mode 2 120 33.3 ATA/ATAPI-4
Mode 3 90 44.4 ATA/ATAPI-5
Mode 4 60 66.7 ATA/ATAPI-5
Mode 5 40 100.0 ATA/ATAPI-6?
It seems to me that HD 1 should be at UDMA Mode 4 and HD 2 at UDMA Mode 2.
I have tried everything to correct this, I have looked throught posts relating to this issue but haven't been successful in correcting it. Any insight into this issue would be a big help.
