Shortly afterward I tried a second usb-sata enclosure. I didn't immediately notice a difference and though it didn't matter. You comments served to make me think again. > while of course that could be coincidence, who really knows what happens in this untrackable inconsistent behavior of the usb-boot?! Unfortunately in this case, human inconsistency (my own, alas) was compounding at least part of the trouble. The more troublesome bridge contains a JMS577 chip, the less troublesome JMS576. https://pdf1.alldatasheet.com/datasheet-pdf/view/1136441/JMICRON/JMS576.html Contains a brief description, but I didn't see much quantitative information. I've reverted the host to the less troublesome JMS576 and will try to reproduce some of the earlier results as a sanity check. Thanks for rattling my cage! bob prohaska > > > >
