Hello again, Had some time to play with libata and this ST340823A drive. I had some problems with 2.6.23-rc2 setup failing at early boot so I kept on going with 2.6.22.1. First, vanilla 2.6.22.1 which works as HPA is not disabled by default: http://bugzilla.kernel.org/attachment.cgi?id=12251&action=view $ egrep "Host Prote|current size|native size|sdb" dmesg_ide_bug_26221_pata.txt ata2.01: Host Protected Area detected: current size: 78165360 sectors native size: 78165361 sectors ata2.01: Host Protected Area detected: current size: 78165360 sectors native size: 78165361 sectors sd 1:0:1:0: [sdb] 78165360 512-byte hardware sectors (40021 MB) sd 1:0:1:0: [sdb] Write Protect is off sd 1:0:1:0: [sdb] Mode Sense: 00 3a 00 00 sd 1:0:1:0: [sdb] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sd 1:0:1:0: [sdb] 78165360 512-byte hardware sectors (40021 MB) sd 1:0:1:0: [sdb] Write Protect is off sd 1:0:1:0: [sdb] Mode Sense: 00 3a 00 00 sd 1:0:1:0: [sdb] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sdb: sdb1 sdb2 sdb3 sd 1:0:1:0: [sdb] Attached SCSI disk Then I went to disabled HPA by default. Actually the drive and filesystem work altough boot looks nasty: http://bugzilla.kernel.org/attachment.cgi?id=12252&action=view $ egrep "Host Prote|current size|native size|sdb" dmesg_ide_bug_26221_pata_hpa.txt ata2.01: Host Protected Area detected: current size: 78165360 sectors native size: 78165361 sectors ata2.01: native size increased to 78165361 sectors ata2.01: Host Protected Area detected: current size: 78165360 sectors native size: 78165361 sectors ata2.01: native size increased to 78165361 sectors sd 1:0:1:0: [sdb] 78165361 512-byte hardware sectors (40021 MB) sd 1:0:1:0: [sdb] Write Protect is off sd 1:0:1:0: [sdb] Mode Sense: 00 3a 00 00 sd 1:0:1:0: [sdb] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sd 1:0:1:0: [sdb] 78165361 512-byte hardware sectors (40021 MB) sd 1:0:1:0: [sdb] Write Protect is off sd 1:0:1:0: [sdb] Mode Sense: 00 3a 00 00 sd 1:0:1:0: [sdb] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sdb: sdb1 sdb2 sdb3 sd 1:0:1:0: [sdb] Attached SCSI disk ata2.01: Host Protected Area detected: current size: 78165360 sectors native size: 78165361 sectors ata2.01: native size increased to 78165361 sectors ata2.01: Host Protected Area detected: current size: 78165360 sectors native size: 78165361 sectors ata2.01: native size increased to 78165361 sectors sd 1:0:1:0: [sdb] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE,SUGGEST_OK sd 1:0:1:0: [sdb] Sense Key : Aborted Command [current] [descriptor] sd 1:0:1:0: [sdb] Add.
