Заметил страннось в выводе hdparm
Вот часть вывода hdparm -I:
Capabilities:
LBA, IORDY(can be disabled)
bytes avail on r/w long: 52 Queue depth: 32
Standby timer values: spec'd by Standard, no device specific minimum
R/W multiple sector transfer: Max = 16 Current = 0
Advanced power management level: unknown setting (0x0000)
Recommended acoustic management value: 128, current value: 128
DMA: mdma0 mdma1 mdma2 udma0 udma1 udma2 udma3 udma4 *udma5
Cycle time: min=120ns recommended=120ns
PIO: pio0 pio1 pio2 pio3 pio4
Cycle time: no flow control=240ns IORDY flow control=120ns
А вот hdparm -i:
Model=IC35L080AVVA07-0, FwRev=VA4OA50K, SerialNo=VNC400A4G2S0KA
Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs }
RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=52
BuffType=DualPortCache, BuffSize=1863kB, MaxMultSect=16, MultSect=off
CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=160836480
IORDY=on/off, tPIO={min:240,w/IORDY:120}, tDMA={min:120,rec:120}
PIO modes: pio0 pio1 pio2 pio3 pio4
DMA modes: mdma0 mdma1 mdma2
UDMA modes: udma0 udma1 udma2
AdvancedPM=yes: disabled (255) WriteCache=enabled
Drive conforms to: ATA/ATAPI-5 T13 1321D revision 1: 2 3 4 5
Обратите внимание на строки DMA/UDMA - для hdparm -i она
явно обрезана. При этом фактически UDMA прекрасно работает
hdparm -t показывает 45 Mb/sec. Да и субъективно
всё работает весьма быстро.
Мама - ASUS A7V8X-X на KT400.
Жесткий диск - IBM AVVA 80Mb.
При этом наблюдается ещё только одна маленькая странность.
При загруженом Linux постоянно горит лампочка активности
HDD. В Windows такого не замечено.
