Hi, I think your problem is whith harddisk(s) S.M.A.R.T. capability not activated in the BIOS settings of the machine (most motherboards I have worked on have it disabled by default). So, go to BIOS settings, locate the S.M.A.R.T. settings and make sure this capability is enabled. If S.M.A.R.T. is enabled, or the problem persists after enabling it, probably you should check if your harddisk(s) S.M.A.R.T support this performance attribute. On the other hand, it seems to me that often the seek performance attribute is not very useful (though marked as "prefailure" on some disks). BR, Petko

Performance monitor is trying to access a disk that is probably not defined correctly in the performance monitor. Accourding to Microsoft this is the registry setting and Disk performance counters can be enabled by using the Hardware Device Manager property pages. NT4 Instance Names HKLMSYSTEMCurrentControlSetServicesPerfDiskPerformance Data type Range Default value REG_DWORD 0 | 1 0 Description Determines whether instances of the PhysicalDisk performance object displayed in performance tools, such as System Monitor, include the names of logical drives residing on the physical drive. Value Meaning 0 Instances of the PhysicalDisk performance object display the drive number and logical drive letters. (New for Windows 2000.) 1 Instances of the PhysicalDisk performance object display only the drive number. (Same as Windows NT 4.0 and earlier.) For example, suppose a physical drive, Disk 0, includes three logical disks, C, D, and E. If the value of this entry is 1, the physical disk instance is represented as 0: C, D, E. If the value of this entry is 0, the same instance is represented as 0. Activation method To make changes to this entry effective, restart the Remote Registry Service or restart Windows 2000. Note Image Note Windows 2000 does not add this entry to the registry. You can add it by editing the registry or by using a program that edits the registry. Tip Image Tip To test this entry on your computer, in System Monitor, click the + button and, in the Performance object box, click PhysicalDisk. View the names of instances in the Select instances from list box. Then, add this entry to the registry, set its value to 1, and view the names again.
