I was having this very same problem and the fix below worked for me (but the actual path was /sys/block/sda/device/scsi_disk:8:0:0:0/allow_restart ). I don't really know much about the linux device model at all, so I'm not sure if that's to be expected.
However, if I unplug the drive and plug it in again, the value is set back to 0 (and the device in the path above would be incremented to 9 so the path would be ... /scsi_disk:9:0:0:0/allow_restart ). Is there a way to set this more generically for this drive? It seems like I shouldn't need to do it every time I plug it in.
