Slow Hard Drive?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



All,

I am running FC6 (with latest update, 64-bit) on AMD Dual Core with 1GB
RAM. It contains a SATA hard disk. I am experience sluggishness when
files are opened or closed (saved). I suspect that i have slow SATA
performance even though i am not sure. I have following stats.

# hdparm -Tt /dev/sda

/dev/sda:
 Timing cached reads:   2452 MB in  2.00 seconds = 1226.48 MB/sec
 Timing buffered disk reads:   86 MB in  3.03 seconds =  28.35 MB/sec

I am concerned about 28.35 MB/Sec speed here.

# hdparm -i /dev/sda

/dev/sda:
 HDIO_GET_IDENTITY failed: Inappropriate ioctl for device

# dmesg | grep -i sata
sata_nv 0000:00:0e.0: version 3.2
ata1: SATA max UDMA/133 cmd 0xE800 ctl 0xE482 bmdma 0xE000 irq 21
ata2: SATA max UDMA/133 cmd 0xE400 ctl 0xE082 bmdma 0xE008 irq 21

scsi1 : sata_nv
ata2: SATA link down (SStatus 0 SControl 300)

# lsmod | grep -i sata
sata_nv                29509  4
libata                120553  1 sata_nv

Kernel Boot Parameter
kernel /vmlinuz-2.6.20-1.2933.fc6 ro root=LABEL=/1 noquiet
combined_mode=libata

Any suggestions/recommendations/comments are welcome.

Thanks

Srikanth
