This may have caused the panic as a secondary effect after the read failed. Thanks for taking the time to respond. Not good news obviously, but could be worse. This is my mule machine. I was using it as a gateway, to develop some networking skills, and had installed SAMBA and was also trying to install HylaFAX . Fortunately it has a second hard drive which currently holds the /var slice. Out with the bad and in with the good. BTW, can the data on this drive be copied to the surviving drive? What commands do I need to review? My initial thoughts were to simply install 6.0 and go on from there. Any hints/suggestions are appreciated. Bob
