Originally titled Device Disconnect/Connect keeps playing. Badum. Dabum. ... Badum. Dabum. At seemingly random intervals I get this noise occurring, despite the fact I could be only doing something like typing this message. It doesn't seem to be my USB devices. I hear the noise even when nothing is connected. One thing I suspect it could be is my hard drive. I noticed that the Disconnect Device icon was active despite there being no device connected to my computer. This was never the case before. I could be wrong, but I'm pretty certain that was neither there before; nor should it be there at all. While yes it's a "device", it's not a "device" in the sense of a mouse, printer, webcam, or fingerprint scanner - other things that appear in the "Devices and Printers" panel. The hard drive shouldn't be one of them should it? Obviously I can't eject it. So, what do I do? Is it even my hard drive doing it? I've recently done a fresh install of Windows 7 after having some frustrations with it, and trying to change to something else. Finding no alternatives that work for my situation (or don't install), I return to Windows 7. Unlike last time, I installed all updates that appeared specific to my HP tx2500, rather than skipping what I didn't expect to use like the fingerprint reader drivers. It's possible an update recognised my hard drive, and is confusing it into thinking it's an external device, and it sounding off the device disconnect whenever its activity goes down. At least, that would be my wild guess. Another difference is that I am using the Microsoft Security Essentials rather than AVG, but I don't expect it to be the cause. --- EDIT: I disabled an unknown device (no details except for located "on PCI standard ISA bridge"), and tried having all devices unplugged and it seems to have stopped. However the confusion remains about the C: drive appearing in the Safely Remove Hardware menu. EDIT 2: Scratch that, there the noise goes again. ... maybe my keyboard is doing it. (I can type fine though. Everything seems to be running fine, except for the USB wireless mouse and that's disconnected.) da page :B

Jabbi - I'm going to go out on a limb and guess that hard drive is a SATA drive of some flavor. If that's the case, it's not entirely unusual. My XP box has 2 IDE hard drives and one SATA II drive - and for someunknown reason, the SATA drive appears in the Safely Remove list - even though Ihave NO need, want nor desire to ever disable the drive.This computer, has 2 internal SATA drives and in XP and Vista, both of those appear on the Safely Remove list. Surprisingly, this computer when booted into Windows 7 - the SATA drives are NOT treated as such. In all cases, Windows - regardless of which version is running treats the drives as being INTERNAL drives. I believe it's possibly a driver issue. Given there IS such a thing as eSATA (or ExternalSATA), in some cases, the driver may mistakenly flagagiven drive is an external/removable drive as opposed to one that's inside the box. As far as what's connecting and disconnecting... I doubt it's the keyboard - if you're typing something and it disconnected and reconnected, you'd notice there was something funny going on. There would be some serious typos popping up if it was the keyboard was the problem.

If you don't want to see your drive listed as a device that you can safely remove, then change your bios settings for the storage controler that the drive is attached to from AHCI to IDE.

I wouldn't know if it's SATA I'm afraid, nor can I see any details mentioning "SATA". I wouldn't doubt that it's a driver issue, considering I blindly installed all driver updates that appeared in Windows Update. In my previous install, I may have missed them somehow or skipped them accidentally. In terms of the keyboard causing the noise, I probably should've said something like the key-presses are causing pressure changes in a connection somewhere. o .o ... nah. Too specific. XDda page :B

I don't see that option. Should it normally be there?da page :B

Proton - Not all systems have AHCI/IDE options. My 4 yr old motherboard certainly doesn't.. It runs SATA drives as IDE by default - and still, my XP and Vista installations on this computer show the SATA drives on the Safely Remove list.

Is there any way - maybe with the Event Viewer - that I can see what's initiating the device disconnect/connect alerts?da page :B

Jaabi-Maybe.. In the Event Viewer log, there may or may not be hardware related events - Take a look...

So far I haven't found anything that seems related to this issue; but I did find something that seems rather odd. Applications and Services Logs > Microsoft > Windows > NlaSvc 2,496 events all the same , many all at the same time down to the second: Gateway resolution failed on interface {20e48606-e93a-4116-8c6d-f8682d15c8de} for 0.0.0.0 with error: 0x57 - < Event xmlns =" http://schemas.microsoft.com/win/2004/08/events/event " > - < System > < Provider Name =" Microsoft-Windows-NlaSvc " Guid =" {63B530F8-29C9-4880-A5B4-B8179096E7B8} " /> < EventID > 4205 </ EventID > < Version > 0 </ Version > < Level > 2 </ Level > < Task > 3 </ Task > < Opcode > 21 </ Opcode > < Keywords > 0x4000000000000002 </ Keywords > < TimeCreated SystemTime =" 2009-07-06T03:43:24.808392700Z " /> < EventRecordID > 6384 </ EventRecordID > < Correlation /> < Execution ProcessID =" 1364 " ThreadID =" 5688 " /> < Channel > Microsoft-Windows-NlaSvc/Operational </ Channel > < Computer > HP </ Computer > < Security UserID =" S-1-5-20 " /> </ System > - < EventData > < Data Name =" InterfaceGuid " > {20E48606-E93A-4116-8C6D-F8682D15C8DE} </ Data > < Data Name =" GatewayIpAddress " > 0.0.0.0 </ Data > < Data Name =" ErrorCode " > 87 </ Data > </ EventData > </ Event > ... is this normal? o .o Well, I searched throughout the event viewer and I couldn't find anything else that closely matched the random periods of the sound effect. ... I suppose I could turn it off, but I found it helpful when I was disconnecting/connecting anything. EDIT: I have found this post that seems to be a similar issue here . However I have no idea what the two files mentioned mean, so I have uploaded them for anyone who does understand them: http://tos.revasser.net/temp/setupapi.app.log 5.8MB? o .o http://tos.revasser.net/temp/setupapi.dev.log 280KB On the topic of the device driver that's confusing treatment of the hard drive - is there a way to uninstall it ... without potentially bricking my computer? (I don't know if uninstalling it normally will necessarily restore the Windows 7 default driver for it.) Only the 'disconnect' sound is playing. I never noticed it before, but now that I've been paying attention, it's always the same sound. da page :B

Proton - Not all systems have AHCI/IDE options. My 4 yr old motherboard certainly doesn't.. It runs SATA drives as IDE by default - and still, my XP and Vista installations on this computer show the SATA drives on the Safely Remove list. Oh, ok. I only saw this behaviour when AHCI was enabled and a hard drive was plugged into one of the sata ports for thestorage controller with AHCI set.None of my internal hard drives shows up in the Safely Remove list. But when I plug in an external HD with the eSata cable, that one shows up.If I plug in a HD cable into one of the four internal ports for the storage controller with AHCI enabled, that internal HD will show up in the list.My other storage controller had IDE or RAID as its options.

Update: Deinstalled the AuthenTech fingerprint reader driver and the noise has stopped as far as I can tell. Unless it's taking a hour long break, I haven't heard it since. At least, it's still in the devices window but no longer in the Programs and Features list. Now about the hard drive driver... since when did it even need one? Windows Update must've got confused about the actual state of the drive and gave me a minor-ly mismatched driver. But how to get rid of it, or at least get Saftley Remove Hardware to ignore it? *is quite confused by now @ _@*da page :B

Jaabi - Personally - I just ignore it. As long as everything else is working - does it matter? Probably not. The safely remove thing goes away into the bubble otherwise.

You're probably right. Even as a "bug" it's not doing any harm. = u=;da page :B
