hdparm
Evening all.
I've been trying to get hdparm to work, but it seems ( I can not verify)
unsuccessfully.
I got
Scorpio:/home/ryn# hdparm -i /dev/hda
/dev/hda:
Model=WDC AC11000H, FwRev=12.07H12, SerialNo=WD-WT364
Config={ HardSect NotMFM HdSw>15uSec SpinMotCtl Fixed DTR>5Mbs FmtGapReq
}
RawCHS=2046/16/63, TrkSize=57600, SectSize=600, ECCbytes=22
BuffType=3(DualPortCache), BuffSize=128kB, MaxMultSect=16, MultSect=off
DblWordIO=no, maxPIO=2(fast), DMA=yes, maxDMA=0(slow)
CurCHS=2046/16/63, CurSects=2062368, LBA=yes, LBAsects=2062368
tDMA={min:120,rec:120}, DMA modes: mword0 mword1 *mword2
IORDY=on/off, tPIO={min:160,w/IORDY:120}, PIO modes: mode3 mode4
an IDE drive (one of my 3), and -i seems to work fine.
However, when I try to do
Scorpio:/home/ryn# hdparm -t /dev/hda
/dev/hda:
Timing buffered disk reads: 32 MB in 7.46 seconds = 4.29 MB/sec
HDIO_DRIVE_CMD failed: Invalid argument
I get that HDIO_DRIVE error message. But it at least read the disk once.
Same error occurs when trying to
Scorpio:/home/ryn# hdparm -S 120 /dev/hda
/dev/hda:
setting standby to 120 (10 minutes)
HDIO_DRIVE_CMD failed: Invalid argument
I guess my question is: What does that error mean, and is hdparm really
setting the sleep time, or does it quit with error message?
I guess I'd find out soon enough, but I want to know for sure.
TIA,
Andrew
