Hi all! I have a problem with drive size detection. After any power cycle my HDD ST31000340NS detected by FreeBSD 7.2 as 31Mb drive. For example: Dec 9 20:33:12 green kernel: ad14: 31MB <Seagate ST31000340NS SN06> at ata7-master SATA300 Dec 9 20:33:12 green kernel: GEOM: ad14: corrupt or invalid GPT detected. Dec 9 20:33:12 green kernel: GEOM: ad14: GPT rejected -- may not be recoverable. # atacontrol cap ad14 [skipped] cylinders 64 heads 16 sectors/track 63 lba supported 65134 sectors lba48 supported 65134 sectors # smartctl -a /dev/ad14 [skipped] User Capacity: 33,348,608 bytes I'm tried to reinit/detach/attach drive via atacontrol, but have no result. But after reboot the system in linux and then back to FreeBSD, I have correct disk geometry: ad14: 953869MB <Seagate ST31000340NS SN06> at ata7-master SATA300 In linux's dmesg.out I found this messages: [ 8.984053] ata6: SATA link up 3.0 Gbps (SStatus 123 SControl 300) [ 9.120175] ata6.00: HPA unlocked: 65134 -> 1953525168, native 1953525168 [ 9.120180] ata6.00: ATA-8: ST31000340NS, SN06, max UDMA/133 [ 9.120183] ata6.00: 1953525168 sectors, multi 16: LBA48 NCQ (depth 31/32) [ 9.179789] ata6.00: configured for UDMA/133 [ 9.179851] scsi 5:0:0:0: Direct-Access ATA ST31000340NS SN06 PQ: 0 ANSI: 5 [ 9.179960] sd 5:0:0:0: Attached scsi generic sg5 type 0 [ 9.179992] sd 5:0:0:0: [sdf] 1953525168 512-byte logical blocks: (1.00 TB/93 1 GiB) [ 9.180041] sd 5:0:0:0: [sdf] Write Protect is off [ 9.180044] sd 5:0:0:0: [sdf] Mode Sense: 00 3a 00 00 [ 9.180066] sd 5:0:0:0: [sdf] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA What is HPA? Why drive locks HPA? And... Can I unlock HPA from FreeBSD? -- MATPOCKuH
