Hello all: I bought a Seagate ES.2 ST31000340NS (1000GB) and run at Gentoo Linux kernel 2.6.24. But Linux kernel report the disk size only 33MB. I tried Intel ICH5 and Sil3112, but get the same result. I don't know this issue was caused by libsata or scsi layer . Could you help me to solved it ? Here is the relative information. I think this would be helpful. == dmesg == ata4: SATA link up 1.5 Gbps (SStatus 113 SControl 310) ata4.00: HPA detected: current 65134, native 1953525167 ata4.00: ATA-6: ST31000340NS, SN04, max UDMA/133 ata4.00: 65134 sectors, multi 16: LBA48 NCQ (depth 0/32) ata4.00: configured for UDMA/100 scsi 3:0:0:0: Direct-Access ATA ST31000340NS SN04 PQ: 0 ANSI: 5 sd 3:0:0:0: [sdc] 65134 512-byte hardware sectors (33 MB) sd 3:0:0:0: [sdc] Write Protect is off sd 3:0:0:0: [sdc] Mode Sense: 00 3a 00 00 sd 3:0:0:0: [sdc] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sd 3:0:0:0: [sdc] 65134 512-byte hardware sectors (33 MB) sd 3:0:0:0: [sdc] Write Protect is off sd 3:0:0:0: [sdc] Mode Sense: 00 3a 00 00 sd 3:0:0:0: [sdc] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sdc: unknown partition table sd 3:0:0:0: [sdc] Attached SCSI disk sd 3:0:0:0: Attached scsi generic sg2 type 0 == Seatool == # ./st -i /dev/sg2 /dev/sg2 Vendor = ATA Product = ST31000340NS Version = SN04 Serial Number = Copyright = SCSI Firmware = Servo RAM Release = Servo ROM Release = Servo RAM Date = Servo ROM Date = Blocksize = 512, Highblock = 65133, Capacity = 33 MB -this is a Seagate drive -this drive does not support DST -Mode Page Settings [current value (default)]: -WCE bit = 1 (0) -RCD bit = 0 (0) -AWRE bit = 1 (0) -ARRE bit = 0 (0) -DExcpt bit = 0 (0) -Number of cache segments = 0 (0) == hdparm == hdparm -i /dev/sdc /dev/sdc: Model=ST31000340NS , FwRev=SN04 , SerialNo= 9QJ09BJ4 Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs RotSpdTol>.5% } RawCHS=64/16/63, TrkSize=0, SectSize=0, ECCbytes=4 BuffType=unknown, BuffSize=0kB, MaxMultSect=16, MultSect=?16?
