Update2: For all the Vista users (mostly x64), please follow the suggestions by deadsimpleand use hdparm if you don't want to deal with the constant "screen brightness" issues that NHC has with vista.Update: This solution has been proven to work with Western Digital and Toshiba Hard Drives in addition to Seagate. Several users reported success while applying the following steps. I can only recommend this to everyone who wants to max out the performance of their HDD and get rid of the annoying clicking sound.Well finally after waiting 6 weeks, I got my inspiron 1520 on Monday.
I have an AUO screen (fortunately not the grainy one, unfortunately with some bad leakage on top/bottom, but tolerable), and my headphone jack is working correctly. The CPU Whine is sorta gone after installing XP.
But just as I thought I got lucky, I heard it....a permanent
clicking noise coming from the hard drive accompanied by the LED light of the HDD.
But before I present you with the solution, my specs:
# Processor: Intel Core 2 Duo T7300 (2.0 GHz/4MB L2 Cache)
# OS: Microsoft XP Professional
# Hard Drive: Seagate 160 GB SATA @ 5400RPM
# Screen: 15.4" WXGA+ Widescreen (1440 x 900) AUO 2077
# Graphics: NVIDIA GeForce 8600M GT 256MB
# RAM: 2.0GB DDR2 SDRAM @667 MHz (2 x 1GB)
# Optical Drive: 8x CD/DVD burner (DVD+/-RW) w/Double Layer Support
# Battery: 6-cell lithium ion
# Wireless: Intel 3945 ABG
Purchase price: $ 1,013
So, after spending countless hours researching the internet for a solution to the
clickingsound of the HDD while being idle, I nearly gave up.
Then I recalled a handy little tool I used a while back with my old acer laptop.
Notebook Hardware Control.Since I identified the
clicking noise as "HDD head parking", I knew the drive wasn't failing (and ofc I ran every possible HDD health check utility) so the only thing I needed now was a utility to change the acoustic management setting of the drive. And you guessed it, Seagate didn't offer anything like that. Thank you Seagate.
But lets get to the solution:
1. Download the NHC 2.0 Pre-Release 06 (
Dell version)
2. Download and install
Microsoft .NET Framework 2.0 (if you don't have it installed)
3. Install NHC
4. Run NHC
5. Go to the newly appeared icon in your system tray and doubleclick

(it's the one with the CPU frequency...so don't confuse it with the RMclock one)
6. In the window that just appeared select the
Settings tab
7. Click
Show all NHC options and settings8. Now select the
Hard Disk tab, and under Advanced Power Management select the highest setting:
Max. Peformance ModeVoila, the constant
clicking sound is gone for good. Have fun.
PS: Ofc you can play around with the settings. Hope this solves the issue for many inspiron users out there.
