Visualize Ram / disk usage desktop application

Hey everyone,
I want to experiment with visualizing realtime ram usage / disk usage in the desktop background, it should also be a bit interactive (when the user moves his mouse the color could change for example) i want to start very basic.
Can someone point me in the right direction how to begin this? I can program in C#/asp.net, i saw some f# examples but i don't even know how to run them :)
Tx so much for any guidance.
Borrie

Hello Borrie,
you can use the PerformanceCounter class to get current RAM usage and disk usage(see
[1] for more information).
For the visualization, you can use the DataVisualizetion package from the WPF ToolKit [2].
There is a sample project about visualizing ram usage at
[3].

How to find disk usage by application

Using the Activity Monitor, I can see that something is making an excessive number of disk IO's and generally slowing the system down.
Is there some way I can see the disk IO on a per-process bases (the same as I can see the CPU usage for each process)?
Thanks
Susan

That does not seem to be it - the process that shows up by far the most messages being sent and received is 'kernel task'.
I think I have tracked down the problem that I was seeking this information to solve (does that make sense?). I have been doing quite a bit of software development, some of it involving installing quite large packages. As these were being installed Spotlight was going crazy trying to index them all and causing the system to slow down because of all the directory lookups etc, it was doing.
At least that is my theory and stopping Spotlight's indexing (I have never used Spotlight anyway - it never seems to find what I'm after) I have not seem the performance hit I was seeing before.
On the other hand, I would still like to know how to monitor disk IOs on a per-process basis for the future.
Thanks
Susan

RAM Issues + High disk usage on MSI GE60

Recently I've noticed that my system slowly eats up RAM. It starts off at 21% and can go as high up as 80% or more. When I'm playing games on it the RAM does not clear up properly either, it stays at 50% or so. This was an issue before that I somehow managed to solve, but it is back again.
As for high disk usage, that's been a problem since I've had the laptop.
OS: Windows 8
Processor: Intel Core i7 4700MQ (2.40GHz)
GPU: NVIDIA GeForce GTX 765M
RAM: 8GB Memory
HDD: 750GB
If you need more info I'll provide it.

If you open task manager-> performance -> open resource manager / you will see whats eating up your resources
if its windows see if indexing is off
did you installed 3rd party software diffrent than stock ?
how old is your laptop?
its not normal to have such high usage numbers !! i think its a program causing the problems !
if you check your resource manager you will be able to see whats causing it
ps if possible please post a screen shot and ill look into it

I need to re install creative cloud and related desktop application after hard disk formatting. Please advise?

My hard disk got reformatted recently, please advise how to re install creative cloud and related desktop application like LR & PS on the same machine.

Hello,
to reinstall CC shouldn't be a problem. You could download all the programs you need in the "try" Version from Adobe's download website. Because you have all needed serial numbers and so on, you can change your programs into "real" versions.
Maybe it'*s necessary, that you have to activate/deactivate pleae have a look there:

KDE 4.7: very slow and high disk usage

Since upgrade to KDE 4.7 on my i686 laptop, my system behaves weirdly. I noticed a slow down caused by a very high disk usage: when the HDD spins the cpu usage reported by the CPU monitor plasmoid is very high (~ 50%), while top reports a very small CPU load. Another strange symptom is that, when I try to close the session, the system freezes for about 15 seconds before the logout/shutdown/restart dialog window appears, again with HDD spinning furiously. If I exit the dialog window and then try to close session again it works smoothly, so I think some caching is at work at second try.
This is very painful since it slows down my workflow. Since now I tried to:
- disable nepomuk, strigi and all that using the nepomukcontroller plasmoid
- disable compositing
- delete .kde folder
- uninstall and reinstall all kde packages
without any benefit. On the same laptop I have dual boot with a 64 bit arch installation, which does not have the same problem, nor has it my 64 bit desktop pc.
Does anyone have similar issues? I don't understand what is it that makes the HDD spin so much, nor how to eventually track it down (are there som HDD usage profiling utilities?). Moreover, why top and CPU usage plasmoid report so different CPU usage stats?
I'm very confused, so any help will be greatly appreciated.

Although I'm not having any of the issues as Snack, I have found KDE 4.7.0 to be a very horrible release. In fact, I'm sick and tired of the KDE release notes bragging about killing thousands of bugs each release, when in actuality the first few revisions of each stable release are horrible. When I first upgraded, I ran into at least four really nasty bugs. Although I've worked around some of them, it left a really sour taste in my mouth. Here is what I've experienced:
1.) With a new user or fresh install, there is no wallpaper by default, even if I install kde-wallpapers before I log in, it makes no difference.
2.) Sometimes kwin will crash during log out.
3.) Worse yet, if I exit a full screen game, it will more than likely crash Kwin. This is a problem on my laptop (which has intel video) and not my desktop (which has nvidia video). If I don't remember to disable desktop effects before opening a game, I may run into a problem.
4.) Although my performance is good, it's not great. I would think a laptop with a Core i5 processor and 8GB of RAM would run faster than it is.
I have tested XFCE for a bit, and I do like it alot. However, with XFCE I am unable to browse Samba shares, and that is a huge problem. In addition, I find KDE's applications to be much better than what ships with XFCE, but I question whether they're worth the performance hit. I really love Kate, Gwenview, Digikam, and Amarok. I know you can install those in XFCE, but they feel out of place and then my desktop pretty much becomes a mutt. Not only that, but KDE is full featured, whereas XFCE is not. It's like I have to choose between a stable desktop or a desktop with full of bugs.
I hope that KDE 4.7.1 fixes everything, but historically it's usually the 4.x.2 release that really does the trick.

Disk Usage stuck at 100%, Factory installed windows 8 running like a turtle not being able to use my laptop. What should i do?

I have a HP Pavillion Sleekbook 15-b002ee with Third generation core i5 processor 1.7 GHz, 500 GB Hard disk and 4 GB of RAM installed. Windows 8 came pre installed on it.
I bought this laptop 11 months ago and it worked fine for 10 months and then from the last month its presenting unusual problems. My disk usage is stuck at 100% and the laptop freezes and never lets me work or do anything. Heres what i have already done
to solve the issue but have been unsuccessful:
1) I have reset my PC completely and reinstalled windows 8 using the factory setup. Didnt solve the issue, newly installed windows displays the disk usage 100% and the performance is same i.e the system freezes.
2) I have tried adjusting my paging file, no change made a difference to the performance of my laptop. The default system managed Paging file size is something around 3.89 Gb. Does my problem have anything to do with my paging file?
3) I have tried solving this issue by disabling the "Windows Search" and "Superfetch" services and still it didnt solve the problem.
4) I have also run checkdisk on my hard drive completely. It took me a complete day to do so but still no change.
5) Before resetting my laptop, an error called "Kernel_data_inpage(http.sys)" used to come on my upgraded windows 8.1. Whats the issue?
So what should i do? Is there any problem with my hardware? Is my hard drive having bad sectors and is that causing the problem? Or is there any other technical problem which i couldnt yet find out?
I have explained my problem in a lot detail and i would like a clear answer please, i have been at this issue for many days and this forum seems like the last place where i can find relevant answer because Google isnt helping.
Thanks in advance.

If you are looking for help on a particular Microsoft product, start your search from support.microsoft.com instead of going to a random Microsoft forum. But since you got a HP laptop, chances are you have software prompted by HP as well, like antivirus/printer

How to erase DVD-Ram disk

I have a half dozen DVD-Ram disks (from my now-dead DVR). They mount on the Desktop and I can see the contents (VRO and associated files). I am exploring the various Toast, Streamclip (etc.) options to play/rescue the files. Once that is done, how can I erase (and rewrite/reuse) the disks? Neither Toast 8 nor Disk Utility seem happy with formatting/erasing this media. Any ideas?
~ Keri

Ah,... makes sense. Thanks! And here's what it says [below].
So, it seems to say I cannot "erase" ... but I can "overwrite" (??), which is splitting a hair finer would have occurred to me.
Okay. Then, how would I "overwrite" the files -- what application could I use to do this? Toast? Other??

Itunes wont disable disk usage

Ok so heres the deal: I just upgraded to a new desktop that runs under windows vista and thought that moving my old library to this new computer would be a snap. I checked out this site for directions on using my 30g classic as a hard drive to make the move. I followed the directions step by step and everything went smoothly up until the "Switch the iPod back to automatic update". I unchecked the Enable disk use tab, hit Apply, synced all my tunes back onto my iPod, but for some reason all the data from my old library is still on it. And it wont let me eject my iPod because it says it contains files that are in use by another application. How can get all that info off my ipod safely?
edit: in a nutshell, I should only have 10.57 gigs of music on my iPod, but it still shows that i have 10.57 gigs of music and 12.40 gigs of "other"
Also, where did all my play lists, ratings, and playcounts go? Can I get them back somehow?

Disabling the "Enable disk usage" should prevent the iPod shuffle from being mounted as a volume on the Mac desktop. In fact, this is exactly what happens in other iPods that allows disk usage.
That's right, but the iPod shuffle is a much simpler design than the bigger iPods, and apparently does not support this. In my experience, the iPod shuffle is generally mounted as a volume whenever it is connected. It also seems that iTunes requires the iPod shuffle to be mounted in order to synchronize it. iTunes will automatically unmount it after synchronization if disk use is disabled, but temporarily mount it again each time it needs to resynchronize it later.
And now it's working. The iPod shuffle NO LONGER mounts on the desktop. Exactly the way it should be with my settings.
I'm afraid that you may be mistaken. Please try the following:
- Quit iTunes.
- Open a Finder window (with the sidebar showing the volumes).
- Now connect your iPod shuffle and wait about 10 seconds.
- The iPod volume should appear in the side bar (and on the desktop).
- The iPod shuffle's LED will be blinking yellow because it is mounted.
- Now start iTunes, which will synchronize the iPod.
- Afterwards the iPod volume will disappear.
- At this time the iPod shuffle's LED will turn to steady yellow or green.
- Arrange windows so that you see both iTunes and the Finder window.
- Select the iPod shuffle in iTunes under Devices.
- Change anything, e.g. drag one song to a different position.
- This will cause iTunes to synchronize the iPod shuffle again.
- While this happens the iPod volume will temporarily reappear.

Spotlight mds bringing down system, constantly leaking RAM & disk access

Spotlight is going rampant here.
The mds (metadata server, aka Spotlight) process is constantly accessing the disk and writing some data to it, filling it until there is no space left on the device. I cannot find out what file it is writing to. I've tried with fsevener which sadly didn't help.
mds is also eating up all the CPU cycles it can get leaving my system fully loaded at all times.
The mds process is also taking up inceasingly huge amounts of memory, causing permanent swapping of memory and bringing the system to a grinding halt. (Cache Hits go down below 1%, About 250.000 pageins happen per minute.) Memory Footprint is going up to several hundred MB or real RAM.
$ vm_stat
Mach Virtual Memory Statistics: (page size of 4096 bytes)
Pages free: 53166.
Pages active: 275736.
Pages inactive: 135633.
Pages wired down: 59698.
"Translation faults": 10217862.
Pages copy-on-write: 136166.
Pages zero filled: 5983710.
Pages reactivated: 96772.
Pageins: 1236330.
Pageouts: 77113.
Object cache: 24391 hits of 1183451 lookups (2% hit rate)
(This is 95 minutes after reboot. Only running: Finder, Terminal, LaunchBar, Safari, Mail)
This bahaviour goes until the disk is full and I get a "low disk space" warning. Then mds crashes, the system frees up the (temporary?) files written by the process and also frees the RAM taken up by it. Resulting in even more swapping, as the system tries to page-in other processes now. Subseqently the system launches a new mds process and the game starts over.
Things I've tried to remedy:
Rebuilt spotlight index several times. Including totally deleting the .Spotlight-V100 folder on local volumes. Doesn't help, takes about 16 to 20 hours to rebuild on my machine, so is not a thing one wants to just-try.
Reinstalled 10.5.5 Combo Update, doesn't help. Privileges are repaired.
Turn off spotlight completely: Does indeed stop the madness, but now I cannot find anything on my system. So this is not a solution at all.
I've tried to keep the index small by excluding more and more stuff in the privacy settings of the Spotlight PreferencePane. This doesn't solve the problem either.
My System:
PowerBook G4 1.5GHz
2GB RAM (Maximum) (Tested with ASD ok, Rember ok. Different RAM modules, also ok.)
160GB HD (5GB free) (SMART ok, Blockscan ok, Filesystem ok, File privileges ok)
Mac OS X 10.5.5 (9F33) including Security Update 2008/007 (no further updates available)
Any help or suggestions are welcome. I'm happy to provide any further details you may need.
Best regards

This probably isn't Spotlight so much as one of the index plugins (mdimporters). Spotlight itself is very robust, however, all it takes is a single bad indexing plugin. MDS, basically, identifies a file type and loads in a list of plugins that are registered for that file type and executes a routine in the plugin to grab the metadata. If the plugin is improperly written, it can go haywire.
Thanks for the suggestion, I already had checked that.
I don't have any custom (read non-apple provided) Spotlight or QuickLook Plug-Ins on my system. So it is unlikely that it is related to a custom .mdimporter Plug-In. (Might be a buggy Apple one going rampant though.)
I've personally found Spotlight to be quite a solid technology as well. Just the user interface provided by Apple is terrible and especially useless in the Finder (Taking away functionality, or making it horrific to use since Tiger… but that is another story.)
What was the last application that you installed prior to it going crazy? Perhaps one of the last 2-3...
Failing that, you can wipeout the metadata database for a Volume like so (from Terminal.app):
*sudo mdutil -E /Volumes/yourvolumehere*
... or '/' in place of '/Volumes/...' for the local disk. You can turn off metadata indexing for a volume entirely like so:
As I already said, rebuilding the index from scratch doesn't help. Completely deleting it, and rebuilding doesn't remedy as well.
*sudo lsof | grep mdimporter*
... which might help you understand what's being used to index, and this:
/System/Library/Spotlight/Chat.mdimporter/Contents/MacOS/Chat
/System/Library/Spotlight/iCal.mdimporter/Contents/MacOS/iCal /System/Library/Spotlight/Mail.mdimporter/Contents/MacOS/Mail

Error Installing Adobe Air from Story Desktop Application Installer

This is truly driving me nuts already.
Every time I try to install the Desktop Application from the Story website, it says I must install Adobe Air. So I click Install, it shows the progress bar to 100%, then errors out with a window. The window header reads "Adobe AIR Installer" and the main section of the window reads "Couldn't write the application to the hard disk. Please verify the hard disk is available and try again." - There is a Retry and Cancel. Retry does it all again with same results.
No, I had no previous versions of Adobe Air. So I tried installing AIR direct from the Adobe website, and it installs fine. So I go back to the Story webpage and try installing the Desktop Application again and the exact same set of events as described above happens. I uninstalled the AIR install, tried again, same result.
I had Production Premium CS3 previously, and installed Production Premium CS5 UPGRADE. All the programs in the suite work like a charm!
I'm running Windows 7 64 bit with 208 Gig free on my C drive, as well as over 500 gig free spread out over two other drives. 8 Gig memory, and two Nvidia Qadro FX 3500 video cards (If that matters at all). Full admin rights to the PC, not limited in any way.
A quick Google search shows plenty of other people having the same problem, just no known fixes I've found!
HELP!!!

Warranty Void query(High Impotence) AND DISK USAGE 100% NEED HELP!!!

I Have an HP Dv6 pavillion 7011tx. after i upgraded this laptop to windows 8, i observed that the disk usage (in task manager) always shows 100% activity..had an Clean boot, tried all the disk checks and management things . rebooted th pc again with windows 8 but still the problem continues..
i dont think there is any solution to this problem as i have seen many many more other posts similar to this problem
COMING TO MY QUERY,
I think that the problem is with bios config, my hardisk type is SATA but the bios has it set to EF mode currently .
Which has made my pc very very slow The insyde h20 bios sucks!
Bios utlilty doesnt has the option even to change it. Is there any solution to this problem?
PC Configuration:
I5 3rd gen intel processor
6GB Ram
600GB HDD
CAN THIS CONFIGURATION ACHIEVE A 100% DISK USAGE EVEN IF NOTHING BIG IS RUNNING IN BACKGROUND?
I AM THINKING TO BUY AN SOLID STATE DRIVE, i hope that it will resolve the problem as it is compatible on both the mode. I will extend my HDD with SDD!
Can i do it myself or shall i have to go to HP CENTER.
DOES MY WARRANTY GETS VOID IF I OPEN THE LAPTOP BACK FOR THIS ?
REPLY ASAP (URGENT)

Hi,
Disk Usage 100% does not mean disk full but there is task which is doing a lot of i/o during that time (probably swap/page file). If nothing using i/o, the number should be down to 0% as shown:
Now, I start a download, you can see both disk usage and Networks activities:
In your case, the utility may do a lot of i/o to the swap/page file. My suggestion: stop it or BUYING MORE RAM.
Hope this helps.

High disk usage/high memory usage.

i keep getting high memory usage and high disk usage in ps cs6.
its slow when i open a file. how can i solve this problem.
thank you.
philip.

Not to put too fine a point on it, but more than what? More RAM is almost always better, but you haven't answered most of the questions posed here. The answer might be different if you have 2 GB of RAM or 32 GB of RAM already. A 9 megapixel document could get rather large with a lot of layers, but again you've neglected to give any hard info about its size.
Regarding your video card, that's a bit of a judgment call you need to make. For Photoshop CS6 I currently advise people to try to get a video card that gets a score of 1000 or better on this benchmark: http://www.videocardbenchmark.net/high_end_gpus.html
Video card speed will matter when you're editing those 3D components and video card VRAM will also matter, but possibly even more importantly your GeForce 320 is a bit old, and nVidia may just not be doing their best driver work for it any more.
Everything in general will run more smoothly with a powerful modern video card. I like to recommend a VisionTek ATI Radeon HD 7750 - or if the computer power supply and your budget allow, the even more powerful 7850. VisionTek does a very good job with their hardware, IMO, and it comes with a lifetime guarantee.
Keep in mind that if you switch from nVidia to ATI or vice versa, you should carefully sweep your system to ensure all files from the old card are removed, then visit the web site of the new card's maker and download/install their latest display driver release.
Best of luck.

hello i am also having the %100 disk usage problem and am starting a thread to upload my etl. file and see if i can get a solution. thnx. i should also mention i have tried every suggestion i have read on the internet even ones that worked for other people
did not work for me i.e. (switching to high performance power plan, disabling cd drive, etc.) no matter what i try "system" is always utilizing 90%-100% of my hard drive and it is driving me crazy.
i can barely do anything on computer without it taking 10x times longer than it should. ive also run dskchk and boot time virus scans and malware scans. all to no avail. i have more than enough ram and a quad core cpu. when i first purchased my laptop it
was running windows 8 and was lightning fast once i upgraded to 8.1 i think is when the issue started occurring.
i am currently installing the windows assessment and deployment kit right now and will upload my etl. file to the skydrive asap.

In order to diagnose this problem please follow these instructions
Install the WPT (windows Performance Toolkit) http://social.technet.microsoft.com/wiki/contents/articles/4847.install-the-windows-performance-toolkit-wpt.aspx ,
open a CMD prompt with administrative rights (right click it>run as admin) and run this command for 60 secs to capture the high HD usage:
xperf -on PROC_THREAD+LOADER+CSWITCH+FILENAME+FILE_IO+FILE_IO_INIT+DISK_IO+DISK_IO_INIT+DRIVERS+PROFILE -f kernel.etl -stackwalk Profile+CSwitch+DiskReadInit+DiskWriteInit+DiskFlushInit+FileCreate+FileCleanup+FileClose+FileRead+FileWrite -BufferSize 1024 -MaxBuffers 1024 -MaxFile 1024 -FileMode Circular && timeout -1 && xperf -d XperfSlowIOcir.etl*When complete, zip the trace & upload it to skydrive (or some other file sharing service) and put a link to it in your next post.

Windows 8.1 100% Disk Usage Problem

I am running a Toshiba Satellite C855D-S5110. 12 GB Ram, 456 GB HD with 311 GB free, CPU Max speed 2.7 GH. My computer, as many other
W8 and W8.1 users seem to suffer, is nearly constantly at 100% disk usage (apparently
I have seen many claims as to what causes this; some even say it involves a bad HD. However, I do not think my HD is bad because
1. My HD was fine before I got 8.1, to the best of my knowledge ( was on 8 prior to 8.1)
2. Most importantly, when my computer isn't in the 100% phases, it seems to work absolutely fine!
I would like help in figuring out what to do about this problem, as well as why it occurs and why it works the way it does (i.e. seemingly just going away for long periods of time).
It is extremely difficult to work when my computer is being very slow, and not knowing when it will happen or what makes it stop happening is frustrating.
I will provide below a list of measures I have taken, edited to include new things tried.
1. Adding RAM
2. Increasing pagefile
3. Running programs to clean up clutter, fix registry problems, free up memory, etc (specifically, Iolo System Mechanic)
4. Disabling the Windows Search Indexing service
5. Checking for updates
6. Running Microsoft Security Scanner (it found nothing)
7. Disabling Live Tiles (of which I only had one in the first place!)
8. One person claimed that their problem went away when they ran Skype, of all things. I tried this, though it did not do the trick.
9. Booting in Safe Mode.
10. Clean Boot.
11. My drive is 0% fragmented.
12. Trying to repair the Windows Image does nothing, as it comes up as being healthy when scanned.
13. sfc /scannow did not fix the problem either.
14. Running Microsoft's performance scanner and uploading the .etl file got me a reply blaming Chrome, which is impossible because
the problem occurs with no programs running. I will try another recording and put it up; the link will be edited in.

Having the exact same problem on a computer after the Windows update installed from 8.0 to 8.1.
Even after reloading the computer from scratch.
The drive activity goes WAY up when booting - to 100%. It then seems to calm down but randomly will go up and down throughout the day peaking at 100%. Even when nothing is open except a MSWord page into which I am typing.
If other programs are open such as Excel and/or Internet Explorer they will display the file name at the top as usual with (Not Responding) at the end. The screen will fade to an opaque look. This lasts for up to approx. 15 minutes at times and the computer
responds to no keyboard or mouse clicks. The mouse pointer on the screen still moves but nothing happens when I click on anything.
I managed to keep the Task Manager visible and it clearly shows less than 20% memory use and less than 5% CPU use when this occurs. But the HDD is at 100%.
The fact that it was fine prior to updating to 8.1 indicates an issue with 8.1 to me. Absolutely nothing else has changed on this machine - aside from Windows Update.
This is a know fault and I hate W8.1. Once it finishes whatever it is doing then there are a bunch of screen flashes as it catches up to what ever and where ever I had clicked with the mouse while it was frozen. It is like it is catching up because W8.1
is causing the HDD to ???????????
Another issue I encounter is the stupid Automatic Maintenance that cannot be disabled. I have found nothing to accomplish this that actually works no matter what anyone has posted on MS sites. It last rendered my computer today useless for approx. +1
hour today!!! I had been using the computer and it was never idle for more than 1 or 2 minutes but yet it started. It is set to run at 1:00 am but it was only approx. 5:00 pm.!!
The Automatic Maintenance is not running however, when the computer freezes and uses 100% HDD as indicated by Task Manager.
Also I can disconnect the computer from the modem or power off the modem and the HDD remains at 100%! So it is not sending nor receiving anything at that time.

Windows 8.0 ntoskernel has producing 100% disk usage

hello i am also having the %100 disk usage problem and am starting a thread to upload my etl. file and
see if i can get a solution. thnx. i should also mention i have tried every suggestion i have read on the internet even ones that worked for other people did not work for me i.e. (switching to high performance power plan, disabling cd drive, etc.) no matter
what i try "system" is always utilizing 90%-100% of my hard drive.
the issue started with windows 7 Ent edition and I decided to reflash the drive Cof my Laptop HP Probook 6470B with windows 8.0 ENT 64 bits and has the
same symptom ntoskrnl.exe is causing hiccups on I/O and delays . The access to C on windows 8 compared h Windows 7 is better but continue showing the issue.
Other peers on the same company not complaint of this delay but I'm sure that they have same symptom.
the symptom is that the Ntoskernel read and write constantly few bytes for fractions of second but repeatedly, the effect is that the queue disk
is high and this issue no let to use the drive C, the system need to wait that the drive is free to let that other applications can use the drive SATA.
I try to share my .etl collected with windows performance analyzer , but "ONE drive" application no let my up more of 100MB in single
file.
If you can help provide some space to upload the file will be appreciated.

Hi Wanikiya,
Unfortunately I can´t remove the Mcafee sw due that is is a policy of my company.
Checking the MS Performance tool you can see that the behavior that show the disk is caused not by Mcafee process. You can select only Process system (4) and right click and select filter selection you can see that the output match exactly with the
disk behavior.
when you put the mouse and click the top 100 % line of the graph you will see a message like this:
Path name- c:\$logfile
IO Init Stack -- [Root] /ntoskrnl.exe ? /ntoskernel.exe?/nto..../fvevol.sys!?/volmgr.sys!/partmagr.sys!?
the Pathname change in each point of the graph but the IO Init stack remain the same.
I'm afraid the the SATA drive is having an issue and windows try to fix.
But if you found something more let me know.
Let me tell you that I'm using bit locker encryption and all the data on my disk has been encrypted.
Any idea will be welcome.
