scsi: st: Tighten the page format heuristics with MODE SELECT

Browse source

[ Upstream commit 8db816c6f1 ]

In the days when SCSI-2 was emerging, some drives did claim SCSI-2 but did
not correctly implement it. The st driver first tries MODE SELECT with the
page format bit set to set the block descriptor.  If not successful, the
non-page format is tried.

The test only tests the sense code and this triggers also from illegal
parameter in the parameter list. The test is limited to "old" devices and
made more strict to remove false alarms.
