Problem:
I keep getting Hash: Element not found errors.
Technical Details:
uTorrent 3.2.3 (latest as of this writing)
Running about 30 Torrents (all downloading)
Win 7 64 bit
Dell N5050 :sigh:
Symptoms:
Force recheck is disabled (sometimes)
When I resume the torrent, as it halts when this happens, it proceeds smoothly until the next Hash: Element not found error
It doesn't happen at a particular %age
Solutions Attempted:
Searched online a lot to find a few below
Re-download elsewhere. Set download folder and change it and re-download the torrent. NO! DOESN'T WORK! and its FRUSTRATING that I'd to DELETE my 90% downloaded torrent!!
Good 'ol thump. Swear at the screen making heavy fist thumps and hand gestures. Surprisingly, this doesn't work!
Force recheck. Doesn't help and sometimes not available.
Disk I/O errors. Came across an article which said this might due to Disk I/O errors.
Realized I was using a DELL laptop
Realized HDD had failed on a previous DELL
Tried Solution #2 again. Same results.
Seemed like the most likely explanation to the problem, hence read articles about HDD checking and downloaded a few suggested softwares to check HDD Health
Interestingly, the HDD was a OK
None of these worked!
I got this error when my hard drive ran out of disk space, so I think it is related to some file / disk access issue, depending on where you are writing to
I was trying to download some large files to a network drive (Windows XP to Samba) and I was getting the same Element Not Found error.
In my case, enabling the disk cache has solved the issue. I had to uncheck the Disable Windows caching of disk writes and Disable Windows caching of disk reads options under uTorrent Options -> Preferences -> Advanced -> Disk Cache (this way enabling the cache).

I really think this question belongs to SuperUser though.
The working solution turned out to be pretty simple.
Check your Anti-Virus!
My antivirus was quietly quarantining a few suspected files.
Added those files to the exclusion list.
All is well again.

I felt this several times before and also now the situation is same as before - always 90~100%.
I checked the almost Youtube video lectures related with this.
I did as following but all didn't help me.
How can I solve it?
1. Start/Run/services.msc -> Disable and stop the "Windows Search" service.
2. Start/Task Scheduler/Task Scheduler Library/Microsoft/Windows/Dfrag -> in the right side, click the "End".
3. Update my drives.
4. superfetch service stop. (in the Youtube video recommended, but there is no such service in my computer,so I was unable to do it)
5. My Computer -> mouse right click -> properties -> Advanced system settings -> Performance -> Settings -> Advanced -> Virtual memory Change setting(as Youtube video)
6. Skype.exe -> properties -> give write access.
7. Services -> Disabled the "Windows Update" service.
But none of this helped me. Any help will be appreciated.
How to fix this?
I tried with this, And maybe it might be different for your configuration.
I wish this will help you.
Mind: Superfetch was changed to Sysmain in new Windows.
Start -> run -> enter: regedit
Go to: Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters
EnablePrefetcher -> modify: enter 2 (default: 3)
EnableSuperfetch -> modify: enter 1 (default: 3)
It worked for me.
I had this problem with my ROG laptop. Disk usage at almost 100% even when idling.
It turned out that the original SSD of the laptop had been swapped for HDD (it was not purchased new). While this is not by itself a problem, as I don't mind the difference in speed that much, the laptop for some reason found it to be. I'm guessing some drivers for the laptop are configured to expect SSD performance.
In any case, my problem was solved by reinstalling the OS on an SSD.

My mac is sending me the frequent alert of low disk space. When I am checking the system storage then it's showing 170+gb is occupied by the system. I am not sure where is my space is getting used?
I tried a few cleaner tools also but couldn't get help much.
Please help to resolve it?
After doing research over various forums of mac's and StackExchange I figured out that it's mostly because of the following reasons.
Log files (Might be crash log files/docker files)
Your email messages stored in outlook (in my case it was almost ~20 GB)
Logs related to cores when a system restarts (~ 10 GB)
Docker Images (This had ~70 GB in my case).
Your nonsystem documents/downloads/itunes
So the question is how to find what all things are unnecessary and safe to delete? These system files are not visible directly.
I tried using a few tools like cleanmymac etc but all were paid so I couldn't get help much there.
To clean up your non-system unnecessary files, you can directly take the help of the storage management tool of mac. You just have to click on optimize storage and it will show all the non-system files.
To cleanup unnecessary system files, use below command
sudo find -x / -type f -size +10G
This command will give you all the files occupying more than 10 GB. You can analyze the files and delete them as necessary.
The highlighted cores are nothing but the state files of your mac to reboot from last state when your mac restarts so it's safe to delete.
Next step is to delete a hidden tmp folder
It will show the size as 0 bytes because your user won't have permission to read it. But will be occupying a hell amount of space. So delete it by giving root permission.
Now, Look if there are any docker images present in your system. Clean them all (Docker.raw).
Using all these steps I was able to clean almost 100+ GB.
Recently found that this issue was caused by a memory leak in one of the Java applications I was running. I had to start the Activity Monitor, searching for Java processes and Force Quit them. Rinse and repeat every time my space runs out. Also fix your code where you can to get rid of memory leaks.

Why do some software require system restart in windows ?
Meanwhile , I have never encountered such situation in Linux based Distros.
It is innate to the way Windows was designed. Loading an executable doesn't load the file into RAM. Windows creates a memory-mapped file for the executable instead. Chunks of the program get loaded into RAM on demand only as needed. A page fault copies 4096 bytes from the file. The RAM pages themselves are not backed by the paging file. If RAM is needed for other processes then Windows simply unmaps the page and throws away the bytes it contains. If the process again lands on the page then a page fault reloads RAM from the file. Very efficient, this mattered a great deal when you need to run a 32-bit operating system and many processes in only 16 megabytes of RAM. Still efficient today, but not as critical as it once was.
One side-effect of the memory-mapped file is that it puts a write lock on the file. Necessary to prevent another processes from altering the executable. That would be disastrous, RAM could contain a mix of old and new bytes in the file. That's guaranteed to cause the program to malfunction.
Of course that makes the life harder for programs that intentionally want to change the executable. Including the malicious variety btw. So having to stop the processes that have the file loaded is required, it releases the write lock. An update delivered through Windows Update tends to update executables that cannot easily be unloaded since they are part of the operating system. Which is the reason they tend to require a reboot, the file is updated as part of the boot sequence when the machine restarts.
One way to bypass the lock is to rename the file. The lock only protects the file data, not the directory entry. You can then create a new directory entry with the same name as the old one. And the next time the process gets started, it will use the new entry. One minor complication is that you have to eventually delete the renamed file.
One thing I can think of is that some software requires services to be running for it to run properly. The restart likely adds these services to the ones that automatically run when you start the computer so that the program can run smoothly.

I'm a bit newbieish when it comes to the deeper parts of OSX configuration and am having to put up with a fairly irritating niggle which while I can put up with it, I know under Windows I could have sorted in minutes.
Basically, I have an external disk with two volumes:
One is an HFS+ volume which I use for TimeMachine backups.
The other, an NTFS volume that I use for general file copying etc on Mac and Windows boxes.
So what happens is that whenever I plug in the disk into my Mac USB, OSX goes off and mounts both volumes and shows an icon on the desktop for each. The thing is that to remove the disk you have to eject the volume and in this case do it for both volumes, which causes an annoying warning dialog to be shown every time.
What I'd prefer is some way to prevent the NTFS volume from auto-mounting altogether. I've done some hefty googling and here's a list of things I've tried so far:
I've tried going through options in Disk Utility
I've tried setting AutoMount to No in /etc/hostconfig but that is a bit too global for my liking.
I've also tried the suggested approach to putting settings in fstab but it appears the OSX (10.5) is ignoring these settings.
Any other suggestions would be welcomed. Just a little dissapointed that I can't just tick a box somewhere (or untick).
EDIT: Thanks heaps to hop for the answer it worked a treat. For the record it turns out that it wasn't OSX not picking up the settings I actually had "msdos" instead of "ntfs" in the fs type column.
The following entry in /etc/fstab will do what you want, even on 10.5 (Leopard):
LABEL=VolumeName none ntfs noauto
If the file is not already there, just create it. Do not use /etc/fstab.hd! No reloading of diskarbitrationd needed.
If this still doesn't work for you, maybe you can find a hint in the syslog.
This is not directly an answer, but
The thing is that to remove the disk you have to eject the volume and in this case do it for both volumes
I have a similar situation.
OSX remembers where you put your icons on the desktop - I've moved the icons for both of my removable drives to just above where the trash can lives.
Eject procedure becomes
Hit top-left of screen with mouse to show desktop
Drag small box around both removable drives
Drag 2cm onto trash so they both get ejected
Remove firewire cable

I know this isn't strictly speaking a programming question but something I always hear from pseudo-techies is that having a lot of entries in your registry slows down your Windows-based PC. I think this notion comes from people who are trying to troubleshoot their PC and why it's running so slow and they open up the registry at some point and see leftover entries from programs they uninstalled ages ago.
But is there any truth to this idea? I would not think so since the registry is essentially just a database and drilling down to an entry wouldn't take significantly longer on a larger registry. But does it?
EDIT: To be clear, I'm not looking for advice on how to make a PC run faster, or asking why my PC in particular is slow (it's not), I'm just curious if people who say "bigger registry means slower PC" are accurate or not.
I think its a symptom, not a cause, as fever is a symptom of an infection.
When you install windows updates, at least in xp and up, a folder called SXS is maintained for rolling them back. These rollback points are also stored in reg keys.
The size of the sxs(side by side) folder grows exponentially and definitely has been linked to why, when some people simple reinstall with sp3 instead of installing sp1 and rolling up to sp3 they get better performance, even with the same programs installed.
1) Start -> Run -> msconfig
2) Check the Startup tab
3) If you don't know what it is, uncheck
4) Reboot
Its not the registry, its the crap you have running in the background.
In short, not really.
In the old days when machines were slower the answer was yes; but having a modern processor rip through even a 60MB registry is not a problem.
Typically, the real reason a modern machine starts running slow is due to everything from malware to virus scanners: Mcafee, Norton's, etc are prime targets in my mind.
Also, the WinSXS folder tends to grow as service packs and applications are installed. This seems to have a negative impact on system performance. There are only two possible solutions in this scenario. First, if possible, reinstall the OS with the latest service pack already slipstreamed into the install. Second, if that isn't possible AND you are running Vista with SP1, you can run the vsp1cln.exe tool (see technet) which will clean up a lot of the older versions of components. Note that this tool can only be executed once and it does not allow you to roll back.
any problems occur on the registry could also make your computer much slower.the fix registry problems you need to install a registry cleaner as this will fix the errors and make your pc back to its normal state.
