AAM software for Barracuda ATA IV?

The following link on the storagereview.com site talks about disabling
'automatic acoustic management' on Seagate Barracuda ATA IV drives. It says
that Seagate's made a utility to do this available on their site (but
perhaps only if you ask for it) - I can't find it anywhere. Has anyone
downloaded this already? I figure I'll check here first rather than wait
for their tech support.

Here's the link to the storagereview article:

Thanks,
Andrew

pop over to IBM's website and download there "featuretools"

follow instructions and make a "bootable" disc

Boot system and you can mess around with your seagates "features"

have fun

Also

just tested the performance diff by switching off AAD using IBM's
featuretools!

scores from HD-tach

Default AAD enabled

seek rate 15.4ms
Data burst rate 69.3mbps
min transfer 28656mbps
max transfer 43252mbps
Average 41690mbps

AAD switched off

seek rate 10.6ms
Data burst rate 70.7mbps
min transfer 30256mbps
max transfer 43264mbps
Average 41688mbps

raises min a little but will you notice it?

Great. Thanks.

I downloaded what sounds like the right tool (haven't tried it yet) at this
location:
http://www.storage.ibm.com/hdd/support/download.htm

Scroll down to 'IBM Feature Tool'.

thx again,
Andrew

Not suited for this task (except for seekrate).

Those are sequential reads, probably even streaming, hardly involving any
seeks. Try a benchmark that does random I/O and you'll probably notice
a much bigger difference.
