The system randomly locks up, it appears applications lock up when they access the USb disk. Also, when accessing the USB disk, the entire system lockup often for minutes. Performance with accessing USB disks is horrendous,. it took 7 hours to copy a directory that was 200 MB. Any program that accesses the USB disk tend to freeze for minutes, and often the entire system becomes unresponsive for minutes. Overall FreeBSD here is characterized by severe instabilities, ive had better performance from Windows 98 systems. The fact that the entire system freezes up, this should not happen, a well designed system will not lock up the entire OS when accessing disk. Are there any diagnostic tools uch as getting a log of tranmissions on USB and probe it, ,or finmd out what code it is lockilng up on ?Has anyone else seen these problems with USB disks?
