Ubuntu系统下查看硬盘信息

Ubuntu系统下查看硬盘信息的方法，可以查看到硬盘的型号、序列号、接口类型，转速，缓存等，这里记录一下。

方法一：直接通过内核查看

$ cat /sys/block/sda/device/modelST31000524AS$ cat /sys/block/sda/device/vendor ATA

方法二：用过hdparm命令查看

$ sudo hdparm -I /dev/sda/dev/sda:ATA device, with non-removable mediaModel Number:       ST31000524AS                            Serial Number:      9VPF38YCFirmware Revision:  JC45    Transport:          Serial, SATA Rev 3.0Standards:这里省略大量信息Configuration:Logicalmaxcurrentcylinders1638316383heads1616sectors/track6363--CHS current addressable sectors:   16514064LBA    user addressable sectors:  268435455LBA48  user addressable sectors: 1949396401Logical/Physical Sector size:           512 bytesdevice size with M = 1024*1024:      951853 MBytesdevice size with M = 1000*1000:      998090 MBytes (998 GB)cache/buffer size  = unknownNominal Media Rotation Rate: 7200Capabilities:LBA, IORDY(can be disabled)这里省略大量信息Commands/features:EnabledSupported:   *SMART feature set    Security Mode feature set   *这里省略大量信息   *SCT Data Tables (AC5)Security: Master password revision code = 65534supportednotenablednotlockedfrozennotexpired: security countsupported: enhanced erase164min for SECURITY ERASE UNIT. 164min for ENHANCED SECURITY ERASE UNIT.Logical Unit WWN Device Identifier: 5000c5003fc5c146NAA: 5IEEE OUI: 000c50Unique ID: 03fc5c146Checksum: correct

可以发现，通过这种方法，看到的信息很全面，连硬盘型号，序列号，容量，接口，转速全都看到了。

方法三：通过lsscsi工具查看

$ sudo aptitude install lsscsi$ lsscsi --device[0:0:0:0]    disk    ATA      ST31000524AS     JC45  /dev/sda[8:0][4:0:0:0]    cd/dvd  ATAPI    DVD A  DH16ABS   PC21  /dev/sr0[11:0]$ lsscsi --list这里省略大量信息

方法四：通过scsitools工具查看

$ sudo aptitude install scsitools$ sudo scsiinfo -l/dev/sda$ sudo scsiinfo -c /dev/sdaData from Caching Page----------------------Write Cache                        1Read Cache                         1Prefetch units                     0Demand Read Retention Priority     0Demand Write Retention Priority    0Disable Pre-fetch Transfer Length  0Minimum Pre-fetch                  0Maximum Pre-fetch                  0Maximum Pre-fetch Ceiling          0

scsitools查看到的信息比较高大上，直接看不太懂。
