lastalive0.dat lastalive1.dat

[Guest]

Hi,

I have something writing to the hard drive once every minute or so. I'm
assuming this is preventing my laptop hard disk from sleeping when off power.

It writes to 2 files, flipping between them: lastalive0.dat lastalive1.dat

The process is svchost.exe.

The files are in:

c:\windows\serviceprofiles\localservice\appdata\local\lastaliveX.dat

The stack trace (according to sysinternals process monitor) is:

0 fltmgr.sys FltRequestOperationStatusCallback +

Is this a known issue?
