The thought that if you reinstall Windows, your installed application programs are safe if they are in a separate partitions is simply wrong. So if Windows goes, the pointers and files go with it. Since programs have to be reinstalled if Windows does, this rationale for a separate partition for programs doesn't work.
In fact, there is hardly ever a good reason for separating Windows from application software in separate partitions. Some people erroneously think that having the page file on a separate partition will improve performance. For best performance, the page file should normally be on the most-used partition of the least-used physical drive.
Some people make a separate partition to store backups of their other partition s. People who rely on such a "backup" are just kidding themselves. It's only very slightly better than no backup at all, because it leaves you susceptible to simultaneous loss of the original and backup to many of the most common dangers: head crashes and other kinds of drive failure, severe power glitches, nearby lightning strikes, virus attacks, even theft of the computer.
In my view,. The reason I call it a false comfort is because I fear that many people will rely on that separation, think that their data is safe there, and therefore do not take appropriate steps to back it up. In truth the data is not safe there. Safety comes from a strong backup regimen, not from how you partition.
However for some people it can be a good idea to separate Windows and programs on the one hand from data on the other, putting each of the two types into separate partitions.
If you backup data only, that backup is usually facilitated by having a separate partition with data only; that permits backing up just that partition easily, without having to collect bits and pieces from here and there. On the other hand, for those who backup by creating an image of the entire drive, there is usually little, if any, benefit to separating data in a partition of its own.
By the way, in all fairness, I should point out that there are many well-respected people who recommend a separate partition for Windows, regardless of your backup scheme. Some people like to treat pictures and videos as something separate from other data files, and create a separate partition for them. To my mind, a picture is simply another kind of data, and there is no advantage in doing this. The comments above pertaining to picture files apply equally to music files. They are just another kind of data and should be treated the same way as other data.
To actually set up a file system and save any files to the drive, the drive needs a partition. The partition can contain all of the storage space on the drive or just some of it.
On many storage devices, a single partition will often take up the entire drive. You must first create at least one container with a file system. We call this container a partition. You can have one partition that contains all the storage space on the drive or divide the space into twenty different partitions. Either way, you need at least one partition on the drive. Files are then written to that file system on the partition. If you have multiple partitions, multiple different drives would appear when you plugged your USB drive into your computer.
However, you may want multiple partitions for other reasons. Each partition can be isolated from the others and even have a different file system. For example, many Windows computers come with a separate recovery partition where the files you need to restore your Windows operating system to its factory default settings are stored. When you restore Windows, the files from this partition are copied to the main partition. If the recovery files were stored on the main system partition, it would be easier for them to be deleted, infected, or corrupted.
Some Windows geeks love creating a separate partition for their personal data files. When you reinstall Windows, you can wipe your system drive and leave your data partition intact.
Linux systems are generally set up with multiple partitions. For example, Linux systems have a swap partition that functions like the page file on Windows. The swap partition is formatted with a different file system. You can set up partitions however you like with Linux, giving different system directories their own partition.
A disk with a traditional partition table can only have up to four partitions. Extended and logical partitions are a way to get around this limitation. Each disk can have up to four primary partitions or three primary partitions and an extended partition. If you find that the organization methods available to you on a single partition aren't enough, adding new ones could help keep your data straight. We've discussed separating your OS files and personal data in most of the above reasons.
But that's not the only use for partitioning a hard drive. You can also add a partition to a drive to install another operating system on it. Perhaps you want to run Linux alongside Windows, but your computer can't handle a virtual machine.
You can create a new drive partition for Linux without touching your existing Windows system. Alternatively, you could install an older version of Windows on a separate partition for backwards compatibility purposes.
Another multi-platform use for partitioning is to work with multiple file systems. While you won't need to do this with your internal drive, it can make external drives more useful if you use them with multiple OSes. Making one partition FAT32 or exFAT would work with pretty much any platform, while you could still keep a separate Mac-friendly file system on another partition.
On the flipside, there are several reasons you should avoid partitioning your hard drive. Here are a few of them. If you're not careful, having multiple partitions could lead to a data loss disaster. While Windows shows separate entries for each partition you've created, those partitions are all still on the same physical drive.
Because of this, if your hard drive fails, is destroyed by a natural disaster, or otherwise stops working, you'll lose everything on it. This could be a shock for a new user, who's used to every drive in the This PC window representing a separate physical device. Thus, backing up your data in Windows , no matter what partition it's on, is crucial. You need to have multiple copies of data for a proper backup. One of the biggest hassles when you have several partitions is keeping them straight.
With any more than three or four partitions, you'll likely lose the organization benefits just trying to keep track of them. And even with an extra partition or two, you'll still have to set up Windows to save your files and software on the other partitions. This is more complex than saving everything on one partition, making it unnecessary for most people. Additionally, the complexity of having multiple partitions introduces more chances for a mistake.
When formatting one partition, you might accidentally erase another. I am surprised that people even know what a partition is.
When I upgraded to Windows 10, my partition was erased. I now use it for extras storage. And yes, I even tested them. Do manufacturers assume that people back up their software? Would it be possible to look at these recovery partitions to determine what they contain?
You can look at them if you have admin privileges. Whether you can understand what is in them is another story. They contain the information to restore a computer to its factory state Windows installation.
It would appear that Microsoft has now made all except the main C: or system partition now invisible when using the disk defragment tool in Windows 10 In previous versions when using the disk defragment tool you could optimise a couple of partitions since usually more than one appeared within it..
However, now it is either the whole hard drive or just the C; partition that is presented for defragmentation or optimisation. What if i want to delete the useless partitions because im about to clone my drive to a completely new computer? I cloned the new drive with Macrium Reflect Free, installed the new drive and it would not load , got the screen that said repair your computer. I swapped the new one back in again and Windows loaded fine, but when I tried to do a fresh backup of the new system, Macrium would not see and of my external hard drives in the usb PE environment, no matter what I tried.
I messed around a bit and remembered this article and I decided to leave the Samsung drive in and somehow restore a backup image of my old drive I took just before I began the swap to the new Sansung drive.
