the tower can hold 5 drives but at present I only have 4 installed. At the end of the log.txt file I sent, it shows the drives being properly discovered and remounted after I plugged the esata cable back into the esata port. do you want me to follow the instructions in usbmon.txt and post the file to the list? Should I just plug in the Addonics adapter without the drives connected or with the raid tower connected as before? thanks, Steve sginn@xxxxxxx On Jun 27, 2011, at 9:56 AM, Alan Stern wrote: > On Fri, 24 Jun 2011, M.
