Mi Recovery 3.0 Wipe Data Means
Etienne Levic
The goal is to securely wipe the data, following the procedures that the customer is asking. Ideally we would like to keep a record of what has been wiped and when, but that would be for audit purposes, not because the customer is asking.
The issue with creating your own script with s-delete is that you will not have any verification and reporting built in to the process and also s-delete has limited support of erasure standards in general.
Thin provisioning is potentially an issue if the configuration is set up so that instead of overwriting a defined location, the write commands will expand the volume if you are targeting free disc space for example. This will all depend on the detailed configuration though.
Speed is always depending on the system and what resources are available. In general all our erasure clients are optimized for erasure speed which is not the priority for a script with an s-delete command for example. However, since we include verification and audit trail in the process as well as running the exact pattern of a chosen erasure algorithm it might be comparing apples and pears if you are looking at an existing process implemented in a different way.
When you change your Chromebook password, it asks for your old password when you sign back in. If you forgot your old password, it erases all local data. Local data is supposedly the files and downloads you've made as well as your Chromebook history. I have had TWO YEARS worth of downloads, and I had forgotten my password. I accidentally signed myself out after changing it, and I was stuck locked out until I entered my old password. Well I had forgotten my old password, and had to click 'proceed' anyways. It erased everything I had downloaded, and I'm PISSED with Google right now. Does anyone know how I could find a way to restore the data I lost?
You can feel free to look through data recovery software options here and try your luck at getting some of your files back, but I would not get your hopes up. If the operating system wiped everything, then it's very unlikely that any of it will be recoverable.
Believe it or not, there is a reason that these systems are in place. If someone were to get ahold of your Chromebook, would you want them to be able to access your potentially sensitive files, even if they didn't have your password? If you lost your device, then I'm sure you would expect that your data would be safe, and that is not possible if your files can be recovered without your password. So, for the sake of the security of your Chromebook, it would be rather concerning if you were able to recover any substantial amount of data after wiping it.
Doing a factory reset on the Android device will remove all the applications installed on the device along with the data associated with them. This brings back all the default settings of the device as it was when the phone was new, giving you a clean slate to start all over again.
Since Wipe data/factory reset deletes all applications, app data, and information (documents, videos, images, music, etc) stored in the internal space, it is required for you to perform a data backup operation before you reset the Android device to factory settings. However, wipe data/factory reset does not affect the SD card in any way. So, even if you have the SD card inserted with videos, images, documents, and any other personal information in the Android device while carrying out a factory reset, everything will remain safe and intact.
Step 1: First of all, turn off the device. Then, use the volume up button, volume down button, and Power button on your Android device simultaneously and hold on to the buttons until the phone turns on.
In some time your device will be reset into factory settings with all your data erased. The entire process will take a few minutes. Ensure that you have the phone at least 70% charged so that it does not run out of charge midway.
First of all, install Dr.Fone on your computer and launch it by double-clicking on the icon. You will find the below window. You will find various toolkits on the interface. Select Erase from various toolkits.
To remove all data, confirm with the given code. After inputting the code, select Erase Now. A message will appear upon erasure completion. Click Erasure Report to review the types of data erased.
Hence, today we learned about wiping data and also factory reset. Well as per us, using Dr.Fone - Data Eraser is the best option as it is a simple and click-through process and helps you completely erase data from your Android. This toolkit also is the best as it supports all Android devices available in the market today.
A factory reset restores a computer, smartphone, etc., back to the state it was in when it left the factory. This includes deleting all the data, apps, and settings the user changed on the device. The next person to use it should have the same experience as when it was first unboxed.
Depending on the electrical gadget, factory resets can be accomplished in a variety of methods. In certain cases, this can be accomplished by accessing the device's Service Menu. Other gadgets may need complete software reinstallation. The following sections will explain the importance of a factory reset and detail how to restore factory settings to various common devices.
A factory reset is a process that clears all data and settings from a device and returns it to its default settings, meaning that the device is reset to the point where it is in the same state it was in when it was first taken out of the box.
Factory reset means that you restore a device to its original system state by erasing all of the information stored on the device in an attempt to restore the device's software to its original manufacturer settings.
Factory resetting the device to its original state helps solve any software or configuration issues, allowing it to function normally again. This can include fixing issues with software updates, fixing errors in the operating system, and improving overall performance.
Some types of data might not be fully erased during a factory reset, and could theoretically be recovered using specialized software. This is particularly a concern for highly sensitive data. To completely eliminate data, the device's storage would need to be securely wiped or physically destroyed.
However, it's crucial to remember that not all malware and viruses can be eliminated with a factory reset. Furthermore, even after a device has been reset to factory settings, some viruses can persist, especially if they have been well embedded into the firmware or operating system; seeking professional assistance in such cases is necessary.
For an organization wanting to maximize the impact of its IT budget, loaner devices are a logical choice. Allowing employees to check out devices as needed prevents waste if they are only using them sporadically, if at all.
However, shared corporate devices create the potential for employees to have unnecessary and unauthorized access to corporate data stored on them. Performing a factory reset of devices between owners helps to prevent these accidental data leaks.
Since a factory reset restores a device to its original state, it can be a solution to these persistent malware variants. Deleting all files and restoring original settings removes the malware and its various persistence mechanisms.
Information accidentally left on sold or discarded devices is a common source of data leaks. Some cyber threat actors will buy them up secondhand to collect sensitive information that was accidentally left on them.
Smartphones commonly have built-in limitations on what their owners can do. For example, the only way to achieve root-level permissions on these phones is to root/jailbreak the device by exploiting a vulnerability in the operating system.
Applications, configuration settings, and other factors that may cause a device to become unusable. If it is running slowly or freezing, the logical first step is to attempt to identify and fix the problem application or setting.
However, a factory reset may be the best option if this does not address the issue. Since this removes all applications and data from the device and resets its settings to factory state, it can likely fix any software-related issues with a malfunctioning device.
The factory reset process differs based on a device's type and operating system. The easy way to perform a factory reset is with data protection tools that offer this feature. If no such tools are installed, here is how to perform a factory reset on Android, iPhone, macOS, and Windows.
An iPhone can also be factory reset by connecting it to a Mac computer. After connecting the device, tell it to Trust This Computer and select it when it appears on the Mac. Under the General tab, click Restore iPhone and confirm by clicking Restore.
On a Windows device, follow these steps to perform a factory restore. But first, if you're using a laptop or another mobile device, connect it to an outlet to keep it charged. If you can't connect your laptop to an outlet, ensure you have a battery charge of at least 50%; otherwise, Microsoft won't let you do a factory reset
Overall, a factory reset can be a helpful tool for returning a device to its default settings and addressing device problems. However, knowing its potential disadvantages is important to prevent losing critical data or further compromising the device.

I was reading another post on destroying IDE drives, and how you could remove data, wipe it, or just destroy the drive. The removed data would still be there in some state, although not easily reachable without software. Wiped data is just removed data, but it has been overwritten and is essentially gone. A destroyed disk, if done well enough, will remove everything, or make it nearly impossible to recover anything. According to my understanding.
