Already solved it!!!!!! For now at least :>) I didnt need to delete the drives. Just use the check box in device manager. After ur suggestion i did a search on PIO mode and found an article explaining why in particular with the sleep state which i use ALL the time. So i made the corrections in registry and have not had a problem thus far. Will reboot and place in sleep mode to see if it comes back but the registry fix should prevent it from happening again. Gotta say it officailly.... You are DA BOMB techie!!!!! Truly living up to your name as Magic Andre !!!!!!!!!!!!!!!! One last thing befoe i go. any reason why my device manager does not have a SATA controller listed under the IDE ATA/ATAPI Controller group. All of my internal drivers are SATA and the Hitachi is a SATA3 (6Gb/s) It says UltraDMA 6 an i feel like im not getting anywhere near the performance of my board and disk drive. If by chance I have to delete them. Will i loose the drive letter or have trouble booting if i delete all my internal drives? Here is the link to the registry fix http://support.microsoft.com/kb/817472 Let me fix it myself Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base: 322756 How to back up and restore the registry in Windows Follow these steps, and then quit Registry Editor: 1.Click Start, click Run, type regedit, and then click OK. 2.Locate and then click the following key in the registry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}\0001 3.On the Edit menu, point to New, and then click DWORD Value. 4.Type ResetErrorCountersOnSuccess, and then press ENTER. 5.On the Edit menu, click Modify. 6.Type 1, and then click OK.

Note The numbered subkeys that are listed earlier correspond to the primary and secondary IDE channels on a computer that contains a single IDE controller. If your computer contains two IDE controllers, the numbered subkeys for the primary and secondary IDE channels for each of the two controllers may be: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}\0002 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}\0003 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}\0004 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}\0005 To verify that you have located the correct subkey, verify that the DriverDesc value for the subkey contains the string value "Primary IDE Channel" or the string value "Secondary IDE Channel."

Yes. In Device Manager I have two ATA Channel 0. The 1st one says ATA Disk in PIO Mode 4 (I beleive that is the Hitachi) The 2nd one says 'Target Id 0, ATAPI Cdrom in Multi-Word DMA Mode 2' & 'Target 1, ATAPI Cdrom PIO Mode 4' I did notice that my device manager does not have a SATA controller listed under the IDE ATA/ATAPI Controller group. Could this be the reason. All of my internal drivers are SATA and the Hitachi is a SATA2

Hi Andre: Your tuotrial is truly magical. It worked like a charm using both xperf and Latency Monitor. After running both test, it seems like the culprit is ATAPORT.sys. I have searched this thread for all instances of ATAPORT.sys to see if someone posted a solution. Unfortunately it seems like there was no real solution... unless i just didnt understand what people did to fix theirs. My version of the drivers is "ataport.SYS", "6.1.7600.16385 (win7_rtm.090713-1255)" I am using a Hitachi Deskstar™ 5K3000 for my internal HD and a Western Digital WD My Book 1110 USB External Drive. I have had this set up now for months with no problems until recently my music was popping and hissing and then I noticed one core at full blast which eventually led me to this thread. Are there any other possibilities other than what I have read so far to alleviate this problem? I realy and truly scoured the net for a solution and tried using this thread to do it myself but i am lost at the moment.
