Lately, I've been experiencing unusually excessive hard disk activity. The drive is constantly being accessed even when I'm not doing anything. Long after I boot up and all my security software checks for updates, the sound continues.
I'm not sure when this started, but I'm hoping someone can offer insight:
- Dell 5150 Dual Core Pentium D. 2.8 GHz
- 2 GB DDR-2 SDRAM, 533MHz
- 512MB ATI Radeon PCIe Video Card
- runs Vista Home Premium, fully patched.
C Drive - Primary - Active, NTFS, 55GB - contains Op System & Applications
- paging file is set constant to approx. 5.3GB and has been defragmented.
Extended Partition containing 2 logical drives, both formatted to NTFS. These contain:
D Drive - Logical, NTFS, 40GB - Music, Videos, Photos & Media temp files
G Drive - Logical, NTFS, 50GB - Backups & Images
Acronis Recovery Partition - FAT32, Primary 40GB
50GB unallocated space
Task Manager does not show any unusual processes or startup enteries. CPU is usually around 5 - 20%. I've disabled all non-essential services. All virus and spyware scans show up negative.
Note: I installed Diskeeper Pro 2007 to auto defrag my drives. Disk activity was "aggressive". I've since turned off auto and will defrag as needed.
The computer does not seem to slow down and responds well to commands and internet browsing.
I'm very annoyed at this disk activity. Any thoughts?
