XPS 1340 Locking Up + nvstor64 Errors

I have the same exact issue after upgrading to Win 7 and using the 64 bit drivers. I have been looking for an answer but with no luck.

Hey Guys!

I have the same problem. 

Using the latest firmware from Nvidia 11.1.0.33. 

Did you find any solutions?

Anyone find a solution for this?  Its getting ridiculous.

So far there does not appear to be a proper solution, however, I have a work around.

The NVIDIA nForce Serial ATA Controller driver supplied with the latest Windows Vista/7 drivers are at fault. To stock the lockups and event log erros simply download the older A00 Chipset driver from Dell. The drivers are only available by choosing Vista as the OS. I extracted the files and then point Device Manager to the drivers to downgrade it to version 10.3.0.42 of the SATA driver.

All lockups have now gone, no more error messages and the Laptop now performs better. Even the bechmark within the driver in Device manager reports a four fold increase in throughput compared to the version 11 driver for Windows 7. I have had no drawbacks from using the older driver.

Hopefully Dell/Nvidia will eventually issue an update to the driver that resolves the issue

@UncleScooby - man! i wish i found this thread 5 days ago!  Event Viewer was logging 180-200 nvstor64, Event ID 129, Reset to device, \Device\RaidPort0, was issued' errors a day for 6 days in a row and the initial Dell Tech support rep did not believe me.  i had corrupted files, indexes, freezing, etc. and it's my (layman's) belief that these delayed read/writes contributed to the demise of my hard drive. Dell Diagnostics was telling me to punt the hard drive, too, WD's hard drive tool was telling me the same thing so i thought it was my hard drive. 

so prior to reading this fix, i purchased a new hard drive (because Dell refused to send me the 500 GB HD that was installed in my laptop by mistake vs 320 GB on the invoice), i installed it and restored from a good backup only to see the same nvstor64 errors within 30 mins of final configuration. there were much less event entries, but the freezing was really bad. next i spent 2 hours on the phone/online with an understanding and willing Tech support person trying to figure out the problem when this thread popped up during my search.  i rolled back to the Vista 64-Bit, NVida SATA A.00 (10.3.0.42) driver and for the last 4 hours not one nvstor64 error.  gosh, i hope this works!  thanks so much for posting your work around!

I am glad some one has found it useful, I found the answer in another forum and posted after trying it out. Since I posted I have had no further lockups and am very happy again, hopefully you will experience the same. I have also contacted Dell support as there are clearly a number of us finding the issue and there is no recognition of the problem. Initially after telling them what I had done the answer came back saying keep checking for later drivers with no axcknowledgemtn anything is actually being worked on. I wrote back again explaining that was not good enough and I want to know that the solution is being worked on and that the Knowledge Base should have an entry for the issue. Here is the response:

"Thank you for replying.

I have reviewed your email and based on that we have already forwarded the issue to our product engineering group for a fix to resolve the issue. As of now, we do not give you any stipulated time period as and when the fix will be released. Please be assured, the issue is under investigation and will come up with the resolution as well.

We have already forwarded your feedback to the concern team.

Should you have any concerns please feel free to write in."

And I have a case number to chase if needed. Fingers crossed they don't take too long and come up with a decent fix.

Normal 0 false false false EN-US X-NONE X-NONE **UPDATE**... ZERO, 0, ZILCH nvstor64 issues for 3 days on my xps 1340. unbelievable!!! i have to wonder what am i giving up by using an older driver vs the newest version? RAID capabilities? NOT!!! Not one time did support suggest i go back to the stock/original driver. Dear Dell, please list this solution as an option for others with the same challenges. NOTE: had to re-post my response, because a (misspelled) word was mistaken for bad language. Brother... fix that bot will ya!

Helloooo.....Dell wake up.

How many people must have this problem before you decide to update the drivers?

So does the A00 work?

Installing A00 put an end to my nvstor64 errors; there are no, zero, ziltch nvstor64 errors in my Admin Event Viewer log since i installed A00. if you're as frustrated as i was, it's worth trying... good luck getting Dell to acknowledge this fix.  it simply will not happen.

Hmmm....

I had a look at the A00 file, but the IDE drivers in there seem to be 32bit (nvstor32.sys), and I'm running W7 x64.

What I did was to uninstall the driver from device manager(it asked me if I wanted to uninstall the software and I uninstalled that, too) and let windows install its default drivers Standard AHCI 1.0 Serial ATA Controller. Run a windows assesment test and I was getting the same results. I did not go the way to banchmark the HDD speed and performace but looks like I have lost nothing by unistalling the driver. Now to install the x32 driver on my x64 system i dont know. I am a bit reluctant.

DELL can you please stop using nVidia motherboard chipsets. They are good only at graphics and stick with the Intel chipsets (never had a problem with those before).

If anyone finds a better solution to nvstor64, please let us know.

In the mean time, thanks to the contributors and a special thanks to the original solution by UncleScooby

i don't know the difference between the 32-bit and 64-bit versions. like you i'm using Win 7 64-bit.  to date, i have not had any issues with my laptop; it's working and that's all that matters to me. :emotion-1:

So is this a problem with the A01 or the A02 file? I have A02 and everything seems to be working fine, although I don't use the laptop for long periods of time, usually shut it down between classes.

The problem is with A02 or the 64bit chipset driver for the SATA controller nvstor64.sys

It is strange as to why in some systems the same drivers works and in some doesn't because it is exactly at start up that I had most of the errors. Dell never has replied or commended on the issue.

List of drivers can be found in http://drivers.softpedia.com/downloadTag/nVidia+MCP79+Chipset+Driver including A00 and A01 but not A02. I don't know the difference between A00 and A01 but they are released to close to each other.
