Just bought a 40GB IBM Deskstar 60GXP. On boot, the system reports:
hda: 40132503 sectors (20548 MB) w/1902KiB Cache, CHS=2498/255/63,UDMA(100)
hdc: 80418240 sectors (41174 MB) w/1916KiB Cache, CHS=79780/16/63,UDMA(33)
hda is my old disk, hdc is the new disk. Does this mean that the new
disk is not operating in ATA-5 (which allows 100MB/sec transfer) mode?
Running hdparm -t -T confirms that the second disk is slightly slower
although the general concesus is that 60GXP is the fastest IDE hard
drive out there ..
/dev/hda:
Timing buffer-cache reads: 128 MB in 0.91 seconds =140.66 MB/sec
Timing buffered disk reads: 64 MB in 1.87 seconds = 34.22 MB/sec
/dev/hdc:
Timing buffer-cache reads: 128 MB in 0.91 seconds =140.66 MB/sec
Timing buffered disk reads: 64 MB in 3.13 seconds = 20.45 MB/sec
Note that the second disk is spinning unmounted and unused at the moment
of running hdparm.
The settings for both hard drives are identical:
/dev/hda:
multcount = 16 (on)
I/O support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 1 (on)
keepsettings = 0 (off)
nowerr = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 2498/255/63, sectors = 40132503, start = 0
/dev/hdc:
multcount = 16 (on)
I/O support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 1 (on)
keepsettings = 0 (off)
nowerr = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 5005/255/63, sectors = 80418240, start = 0
This doesn't really much to me, I am just curios why those two kernel
are not consistent with each other..
