I have a removable disk of type RDX, connected by SATA to my linux machine. I access it via libata on /dev/sdb, like a classical disk. I write to it a certain time with some mounts and umounts. After a certain number of mounting and unmounting, or maybe a certain number of hours (not clearly identified), the device refuses to be mounted, saying "You must specify the filesystem type.". Looking to /var/log/messages I have the following logs : Jul 15 14:55:54 testrdx kernel: sd 0:0:1:0: [sdb] READ CAPACITY failed Jul 15 14:55:54 testrdx kernel: sd 0:0:1:0: [sdb] Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK,SUGGEST_OK Jul 15 14:55:54 testrdx kernel: sd 0:0:1:0: [sdb] Sense not available.

My system is : linux kernel 2.6.21.1 with some patches : - libata-start_stop_management (http://bugs.gentoo.org/attachment.cgi?id=118829) compiled with libata. Motherboard ICH6 family (id 2651) Does anyone know this problem or have an idea about what it is and what to do? Thank you in advance Pascal
