Say, has anyone noticed when Safeboot is installed there is frequent (every 0.5 sec) hard drive access on Dell Precision M4400 laptops even after initial encryption is complete? I have 3 with Safeboot and one without. When Safeboot is installed the HDD is being accessed frequently.
However, when I remove the optical drive, the HDD access is minimal (every 30 sec).
Could there be a Dell firmware incompatibility with Safeboot or otherwise?
Any and all comments much appreciated..
Using process monitor, I have not been able to fully identify what process is accessing the drive. The most likely suspects based on the trace are vsmon and safeboot. But, the trace does not show the access from these two apps as being as repeatable as that being observed. With that being said, one key indicator is that a relatively new machine of the same make and model that has essentially identical core applications in the build with the exception of SafeBoot does not exhibit the constant disk access. I am also working with Dell to see if they have any ideas.
I would get a copy of psmon and see what's going on. As you say, once EEPC has finished the initial encryption, it doenst need to touch the drive again.
Maybe it's a virus scan, or indexing going on?
I ran the unit in Safe Mode with and without network support and it exhibited the same problem. I don't know, however, that this entirely eliminates Safeboot as a source of the problem.
Process Monitor is useless for this task.
Process Explorer is much better, but still will not tell you what function in that process, performs particular I/O's.
Why is process monitor not useful? It will show you in real time what files are being accessed, and by what task? Isn't that the question here?
Process explorer shows you what functions own what files etc, but the problem here is continuous disk access.
It seems to me that's easier to work out if you can see a list of what is accessing the disk...Message was edited by: SafeBoot on 4/28/10 11:09:36 PM EDT
