Does a filled up hard disk slow down your computer?
First and foremost is memory swapping. Windows use Hard disk to swap its memory for working. Over period of single usage these swaps also known as Virtual Memory or Paging File increases and fills up your hard disk space. This will significantly slow down your computer if your hard disk does not have enough space.Fragmentation: If you work on large files doing multiple editing, fragmentation occurs. Hard disks do not store files as one chunk, but instead in clusters. The clusters tail information will provide the location of the next cluster. So in order to load one complete file, the hard disk will have to make several trips on the spindle to locate all the clusters and get the file. Modern OS reduces these fragmentation by providing good buffer spaces for a file (8K or 16K File Allocation Table) . Yet, this is unavoidable. Defragmenting the hard disk will provide some relief.As you fill to 90% of the hard disk, expect the system to slow down. Larger size hard disks have thousands of files which are to be properly indexed. at 90% usage, the memory may not be sufficient to keep all the indices of file and the OS will resort to swapping it in the hard disk itself. Hence larger the hard disk, more space would be required for this. In general we advice when hard disk is at 80% capacity look for archiving, or deleting files or add additional hard disk to ensure smooth operation of the computer.
Can overfilling an external HDD make it stop responding?
There are several things that I would try. Boot with a different OS and see if you can access it that way. This may allow you to at least move the important files while you diagnose. Check "permissions." Some versions of windows I have used have had the odd habit of randomly reassigning permissions and denying me access even as administrator without jumping though many hoops. This is particularly a problem when you use a drive between multiple computers. Have you checked the manufacturers website to see if this is a particular known issue with this drive and if there is a patch or work around? Have you tried to drive on another computer to see if you can access it ( similar to the second OS choice). Have you tried it with a known good cable and in another slot ( or port depending on how it connects). Are all your slots good and are they all available ( my motherboard, for instance, has an msata slot, but if you use it you can no longer use one of the main sata sockets.) These are all things I would check/consider. Okay, in Disk management, see if the "mount" option is available. It's only happened to be once, but I did once have a disk come "unmounted" in disk manager. Actually one other thing, the first I should have mentioned, is to check BIOS. It can sometimes get wonky if you have a powerspike or outage, and make sure the disk is recognized there.
What does buffer mean in C?
The idea of buffering is general in computation, it is not specific to C.A buffer is an area of memory, set aside for temporary storage of data. Wikipedia (Data buffer - Wikipedia) defines a buffer as:a data buffer (or just buffer) is a region of a physical memory storage used to temporarily store data while it is being moved from one place to another.Examples of when you use a buffer in C (applicable to other languages also):Reading the contents of a file, before applying some operation (like parsing records, etc) on the data.Saving user input, while awaiting further input.This is the commonest use in C. A buffer will usually be declared as an array of char or uint_8, although it can be of any type, include void * (Please note you can’t dereference the void pointer directly, you will need to cast it to another type in order to access the contents of the buffer).You may also hear the term buffering in relation to the standard IO streams library. One of the functions of the Standard IO Library (stdio.h) is to handle Input/Output buffering. That means when you read/write to/from files, the stdio library intervenes and buffers these operations. The buffering mode is usually either Full Buffering, Line Buffering, or No Buffering (all defined via macros in stdio.h). You can easily tweak the buffering mode of any open file stream by using the setbuf() function call.
Can disk formatting resolve fragmentation?
20 years ago I needed to defragment my hard drive every couple of months because that was the biggest cause of slow performance. Instead of getting a file from one location, bits of it had to be retrieved from several hundred and that took much longer.With today’s much faster hardware fragmentation has to be really bad before it has much effect on performance, and I haven’t needed to defrag for a long time.The biggest problem now is left-over junk files from today’s third-generation programs which would cost several times as much to develop if a team of humans had to sift through thousands of lines of code to make sure every temporary file was deleted on closing, particularly since any block of code can call an external utility which may itself create temporary files. They’re often only a few bytes but finding the file the OS wants takes much longer if it has to search through many thousands. That’s why a de-junking utility like Advanced System Care has become much more useful than a defragmenter.One unforeseen consequence in the middle years was the Prefetch file which seemed like a good idea at the time. Whenever the OS had to search for a file it posted a quick link in Prefetch for the next time it was required. Except that as Prefetch grew really large it took longer to search its quick links than a direct search would require and defeated the original purpose,
How much space is reserved by recycle bin?
Recycle Bin is a virtual folder that stores only the information of files deleted in Window Explorer by users. It doesn't have a path or a fixed capacity. The capacity of the Recycle Bin is determined by each volume size.In Windows operating systems with NTFS filesystem, each volume has a $Recycle.Bin folder under it, which normally is set to Hidden. The capacity of Recycle Bin is the total size of each $Recycle.Bin combined. The calculation might vary in different versions of Windows but starting with Windows Vista, the algorithm for default $Recycle.Bin size is ten percent of the first 40GB of volume size/quota, and five percent of any remaining volume/quota above 40GB.For example, if you have a 100GB hard drive, the capacity of the $Recycle.Bin folder of this drive is 40x10% + 60x5% = 7GB, which is 7168MB. If you attempt to delete anything on this drive bigger than 7168MB, the operating system will show you the "File too large for recycling bin do you want to permanently delete?" message. If you choose permanently delete, the file will bypass the Recycle Bin and be removed straight way. As the deleted files slowly fill up the recycle bin, older files will be cleared out to make room for newly deleted files.Data Recovery: Restore Files Too Large for Recycle Bin
Nobis 9 " tablet wont go past go?
You need to do a factory reset . Press gently the “reset pin-hole” present generally on a side of Tablet. Use a clip-pin or similarly fine thing to gently push inside to reset your device to factory settings. That should reset to factory original condition.
How would installing high number of software still slow down the PC even if they all are installed in external SSD & disabled to run at background ?
I am interpreting that you have external SSD drives. You don’t mention whether your internal/boot disk is SSD or HDD. I am assuming that it is HDD.The bottlenecks in PCs are the mechanical hard drives and the amount of memory installed. If you want to make your PC faster, replace your internal HDD with SSD if you haven’t done so already.Installing your software in an external hard drive is not the answer. External hard drives use serial technology to render files and data. While USB 3 is really fast, it is still a lot slower than an internal SSD.A good strategy is to install the software that you use the most in your internal SSD, large files like movies, music and photos in external SSD. Make sure you don’t overfill your SSD, 2/3 should be the max.Memory (RAM) comes into play only after your first load your software. If you load it from an internal or external HDD it will not load fast. Once it is loaded if you have enough memory then they will run really fast. What is enough memory? For HDDs more than 8 gigs, for SSD 4 is usually sufficient. When you load up too many programs (multitasking) then the free space in your hard drive comes into play as it shuffles part of the software to the drive and back. This is when not having too much junk in your hard drive comes into play. Of course with a HDD this shoveling back and forth slows down performance significantly.For a fast computer you should have internal SSD instead of HDD and as much memory as you can afford. I run SSD and 16 gigs in my main computer. It boots up in less than 4 seconds and software is active in less than 2.
