From 18b2466c3050e23c98bb69bd3f35295ff8164851 Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Wed, 8 Aug 2007 14:28:49 +0100 Subject: [PATCH] libata-core: Allow translation setting to fail On some early drives (pre ATA1) this feature is not supported. If it fails then we know the drive geometry is the hardware geometry and the one we tried to set anyway so just carry on.
