        Hello,

        i have a problem accessing an ATA disk on a Solaris 10 x86 server. The file systems on the disk became inaccessible and i found the following portion of messages in the /var/adm/messages log.

        Apr 17 19:01:20 host.tld.com scsi: WARNING: /pci@0,0/pci-ide@f,1/ide@1 (ata5):
        Apr 17 19:01:20 host.tld.com timeout: abort request, target=0 lun=0

        Apr 17 19:01:20 host.tld.com genunix: ata_disk_iosetup: byte count zero

        When i tryed to access the disk via the ``format'' command, it freezes for a long time and produces the messages above.

        Cound someone point me whether the controller or the disk has problems, or both ?

        Thanks in advance!

                Vladimir
