(...) Wow! Just to prevent from a disaster, ensure you have a full and updated backup copy of your whole data. Then you can proceed with some basic tests: 1/ Check the cabling inside the computer, mainly sata cables, they could have been moved or be badly seated (ensure that all sata connectors are firmly tighten). 2/ Use sata quality cables when possible. For testing purposes, you can try with a different sata cable, at least for the device attached to ata6.00 port ("dmesg | grep -i ata6.00" will tell what's hanging there). 3/ Download the disk utilities from the hard disk manufacturer (which usually runs from an ISO livecd) and scan your hard disks for smart or another errors (always run soft/non-destructive tests). 4/ From a LiveCD, you can additionaly get the results from "smartcl" long test mode to compare with the results from step 3/. And provide the results of all these set of tests :-) Greetings, -- Camaleón -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
