linux系统下如何知道配件配置和测试硬盘? 测试硬盘的读取速度 是SATA 还是SCSI之类的. 硬盘是否有坏道.

Options:
-a   get/set fs readahead
-A   set drive read-lookahead flag (0/1)
-b   get/set bus state (0 == off, 1 == on, 2 == tristate)
-B   set Advanced Power Management setting (1-255)
-c   get/set IDE 32-bit IO setting
-C   check IDE power mode status
-d   get/set using_dma flag
--direct  use O_DIRECT to bypass page cache for timings
-D   enable/disable drive defect management
-E   set cd-rom drive speed
-f   flush buffer cache for device on exit
-g   display drive geometry
-h   display terse usage information
-i   display drive identification
-I   detailed/current information directly from drive
--Istdin  read identify data from stdin as ASCII hex
--Istdout write identify data to stdout as ASCII hex
-k   get/set keep_settings_over_reset flag (0/1)
-K   set drive keep_features_over_reset flag (0/1)
-L   set drive doorlock (0/1) (removable harddisks only)
-M   get/set acoustic management (0-254, 128: quiet, 254: fast) (EXPERIMENTAL)
-m   get/set multiple sector count
-n   get/set ignore-write-errors flag (0/1)
-p   set PIO mode on IDE interface chipset (0,1,2,3,4,...)
-P   set drive prefetch count
-q   change next setting quietly
-Q   get/set DMA tagged-queuing depth (if supported)
-r   get/set device  readonly flag (DANGEROUS to set)
-R   register an IDE interface (DANGEROUS)
-S   set standby (spindown) timeout
-t   perform device read timings
-T   perform cache read timings
-u   get/set unmaskirq flag (0/1)
-U   un-register an IDE interface (DANGEROUS)
-v   defaults; same as -mcudkrag for IDE drives
-V   display program version and exit immediately
-w   perform device reset (DANGEROUS)
-W   set drive write-caching flag (0/1) (DANGEROUS)
