Hardware is the most likely... I have a 2000 with a 4MB 2630, 2MB Micron mem board and a 2091 with a 40MB Quantum drive. The drive has four partitions, a small 2MB dualboot partition, a 10MB 1.3 partition, a 10MB 2.0 partition, and the rest is work space. The four partitions have buffers set to 20, 100, 100 and 100 blocks using HDToolBox. Under 1.3, once I have opened and closed the partition icon and displayed the window, subsequent openings occur from the buffer memory and no disk access is made. The buffers seem to be working OK. However, under 2.0, the disk is accessed every time the icon is opened. ie open/close/open produces two disk accesses whereas only one is made first time under 1.3. It appears that 2.0 ignores the buffers, or the automount doesn't work correctly. What's happening ? (This problem occurs independently of the 2630). ------------------------------------------------------------------------------ Phil Williams cbmuk!cbmuka!pharma!philw Dept Pharmaceutical Sciences Univeristy of Nottingham JANET: paxpw@uk.ac.nott.vax Nottingham NG7 2RD UK
