next in thread | raw e-mail | index | archive | help
I use a DGVS09U hard disc drive (8.7 GB) with 68-pin connector at an
Adaptec 2940 UW controller. As shown below the driver always reports
only 10.0 MHz for the drive. It is the same speed like for the other
hard disc (Quantum) with 50-pin connector.
The drive with 68-pin connector should work at 20 MHz, shouldn't it?
Can someone help me?
