Wow, an answer directly from Plasmon, that's nice. :-) I've already got the FUSE driver (udofs-1.1-92.i386.rpm, based on FUSE 1.4, is this current?!). It is nice for a standalone drive, but we use a SCSI robotic changer in conjunction with an HSM system (Legato DiskXtender 2.9) which needs some kind of direct access to the drive. It probes for /dev/nst*, but I guess /dev/sd* would also work.
I know this exact configuration is not officially supported, but I'm a bit dissapointed that the limiting factor seems to be the Linux kernel. If I don't find a solution, it will probably become a Solaris/SPARC solution next week. :-( Cheers, Johann On Friday 22 July 2005 20:18, Steve McIntyre wrote: > Johann wrote: > >Hi everybody, > > > >i'm trying to access UDO/WORM mediums (which have a sector size of > >8192) via a Plasmon UDO drive, but all I get is "unsupported sector > >size 8192" when I try to access it via /dev/sdX. drivers/scsi/sd.c > >suggests that the maximum sector size currently supported by Linux is > >4096. > > > >How difficult will it get to support 8192?
