Hi,
Караул! Поможите люди добрые...
Есть винт:
hdparm -i /dev/hda

/dev/hda:

  Model=SAMSUNG SV4002H, FwRev=QP100-07, SerialNo=0379J1FT137559
  Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs }
  RawCHS=16383/16/63, TrkSize=38997, SectSize=619, ECCbytes=4
  BuffType=DualPortCache, BuffSize=1945kB, MaxMultSect=16, MultSect=16
  CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=78242976
  IORDY=yes, tPIO={min:120,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 udma3 udma4 *udma5
  AdvancedPM=no WriteCache=enabled
  Drive conforms to: ATA/ATAPI-6 T13 1410D revision 1:

  * signifies the current active mode
Видно, что стоит режим udma5. Винт ТОРМОЗИТТТТ безбожно.

hdparm -t /dev/hda

/dev/hda:
  Timing buffered disk reads:    2 MB in  8.72 seconds = 234.84 kB/sec

Такая скорость практически постоянно. Никаких жалоб на винт на 12ю 
консоль не падает. Если дать команду hdparm -t /dev/hda несколько 
раз подряд, винт постепенно разгоняется до приемлемых значений.
  hdparm -t /dev/hda

/dev/hda:
  Timing buffered disk reads:   50 MB in  3.54 seconds =  14.11 MB/sec
Но, как заставить его работать нормально постоянно?!
