New page

==Overview==

Runs hdparm -t, seeker and Nates dd script.

By default each test is run 3 times to get a good running average.

Outputs are cleaned up to provide usable information

For Nates dd test you will need to have the drive mounted and listed in fstab

==Script==

<code>[javascript,n]
#!/bin/bash

testpath=`grep $1 /etc/fstab | awk '{print $2}'`
testcount=3

echo "Testing hdparm -t $1"
for i in `seq 1 $testcount`;
do
hdparm -t $1 | grep "Timing"
done

echo "Testing seeker $1"
for i in `seq 1 $testcount`;
do
seeker $1 | grep "Results"
done

echo "Testing DD pv"
for i in `seq 1 $testcount`;
do
sync
echo "Write Test"
dd if=/dev/zero bs=1M count=2048 2>/dev/null | pv | dd of=$testpath/ddfile 2>/dev/null

sync
echo "Read Test"
cat $testpath/ddfile | pv > /dev/null

rm -f $testpath/ddfile
done
</code>
==Usage==
<code>[bash,n]
sh hdtest <drive path>
</code>

==What to change==

testcount This should be set to the number of times you want this test to run.
