Ticket #11149 (closed defect: duplicate)
Constant disk read
|Reported by:||gaborca||Owned by:|
I have got a relatively old harddrive in my PC, and recently I noticed that it keeps constant disk reading (or writing) when I run particular programs, because it has got audible seek sounds. After investigating a bit (stopping all my software, and starting them one by one) it turned out that VirtualBox is making that noise.
To prove it, I downloaded and ran ProcMon from Microsoft ( http://technet.microsoft.com/en-us/sysinternals/bb896645.aspx), chose Filter (ctrl+L), and added two rules: "Operation is ReadFile" and "Operation is WriteFile". VBoxSVC.exe and VirtualBox.exe make together about 300 disk reads in the ProcMon process reading refresh period (in 2 or 3 seconds). The weird thing is that both processes keep reading the same file, C:\Program Files\Oracle\VirtualBox\VBoxC.dll, about 100-200 bytes, and they start it over and over again. You can see that on the attached screenshot of ProcMon, and I also upload that onto my website.
My host is: Windows XP SP3 This bug is present in 4.2.0 and also in 4.2.4 (the newest one) The bug is present in all guest I started (Windows XP, Debian, OpenBSD) The bug doesn't generate visible CPU load, but I fear it wears the disk
