Driver with tag "Stor" on Windows XP (32 bit)

Question

I have a leaking driver (leaks 40-60MB/day) on Windows XP (32 bit). I used poolmon.exe from Server2003 SP2 (file-date is in 2007), I get:

Stor Nonp 169527 ( 13) 950 ( 0) 168577 49377328 ( 3744) 292 Unknown Driver

After hours of googling and searching my *.sys files for strings, I am still not able to identify this driver. Has anybody encountered it?

TIA, Radim

Here is "driverquery /V" output:

@Radim: Post the results of a "driverquery" from a command-prompt somewhere. Odds are that most of the drivers can be eliminated from question that way, and whatever is left ought to be a pretty small group to search thru. — Evan Anderson, Jun 30 '09 at 22:15

Everything I have seen seems to link this to a storage device driver, mostly related to Qlogic or Nvidia RAID setups. Hope that helps.

Probably this one:

I've had no problems with this driver myself. If I were you, I would try to upgrade/change to a different one.

iaStor.sys was my original suspect, but it is listed in the poolmon output and seems to have reasonable and stable numbers. – Radim Cernej Jul 01 '09 at 13:51

There was a previous post that had issues with the iaStor, specifically with the Intel ICH9R controller - both hardware/software wise. IMO, an on-board RAID controller is useless. Intel, nVidia, HighPoint whatever. Now, on-board controllers for workstations are all the same: awful. But in the server market it's a little tricker to determine if the on-board solution is the real RAID or not. Personally, whatever equipment you buy you should research the specs to see exactly what you're getting (or getting into).

I'm not sure if you're running RAID or not, but using on-board RAID will ultimately end up causing more headaches then preventing them. If you need RAID for speed (RAID0) on-board controllers or even software RAID is fine by me. But if you need redundancy, get the real thing and buy a PCI-e/PCI-x/whatever-bus-you-have controller with a real processor and RAM (hell even a battery if money isn't a concern). You'll thank yourself later.

Just my two cents. Sorry for the diatribe.

I am still doing some checks, but I am >95% sure that the leak was caused by Daemon Tools v3.46. I had this virtual CD/DVD software installed since 2004, something else had to trigger this leak (a Windows update, etc.). I removed the Daemon Tools and now the Poolmon tag "Stor" does not show up. Also, the file atapi.sys is now showing with Microsoft version info, before the uninstall it there was no version info embedded in the file. Daemon Tools have served me well over the years, but I will remember this pain for a long time :).

Confirmed, Daemon Tools v3.46 driver was the cause. I removed Daemon Tools and not the PC has been healthy for several weeks. — Radim Cernej, Sep 09 '09 at 12:45
