واقعا قطع کردن فلش از کامپیوتر نیاز به safely remove دارد؟

Summary

In this informative video, Ardeshir Kaviani discusses the necessity of safely removing flash drives on Windows systems. He clarifies that while it's often unnecessary, there are specific conditions—like using an external hard drive or working with files in progress—that warrant the use of 'Safely Remove Hardware'. The video also covers the impact of 'Write caching policy' on performance and data safety, advising viewers on when it's crucial to eject devices properly to prevent data loss or corruption.

Takeaways

• 😀 The script discusses the necessity of using the 'Safely Remove Hardware' option when disconnecting a flash drive from a computer.
• 🔧 Most of the time, it is not necessary to use 'Safely Remove Hardware' for Windows systems, but it is important for Linux and macOS.
• 🖥️ The behavior of safely removing hardware can depend on the operating system and the type of device connected, such as a hard disk, SSD, or flash drive.
• 🔌 For Mac and Linux, it is recommended to always eject the device before physically disconnecting it to avoid data corruption.
• 💾 Windows systems usually handle device disconnection differently from Mac and Linux, often allowing for direct disconnection without the need for an eject command.
• 🛠️ The script mentions that certain conditions and parameters, such as the device being in use or specific Windows settings, can affect whether you need to eject a device safely.
• 🔄 The 'Write caching Policy' setting in Windows can influence the need for safely removing hardware, especially when set to 'Better Performance'.
• 🚫 If a file is open and being used from a device like a flash drive, it is crucial not to disconnect the device without properly ejecting it first to prevent data loss or corruption.
• 🔍 The video script advises viewers to watch until the end for detailed explanations on when it is necessary to safely remove hardware and when it is not.
• 🔗 The 'Safely Remove Hardware' policy in Windows can be managed through device properties and is related to the 'Write caching' feature.
• 🔌 USB ports and the power supply to connected devices can also affect the safety of disconnecting a device, with potential physical damage occurring if not handled properly.

Q & A

Is it necessary to use the 'Safely Remove Hardware' option when disconnecting a flash drive on Windows?

In most cases on Windows, it is not necessary to use the 'Safely Remove Hardware' option, especially if you're using a flash drive and not an external hard disk or SSD. However, if you have changed the default settings in Windows or are using Linux or macOS, you should eject the device properly.

What are the conditions under which it is necessary to eject a flash drive before physically disconnecting it?

It is necessary to eject a flash drive before disconnecting it when using macOS or Linux, regardless of the type of storage device. In Windows, you should eject the device if it is an external hard disk or SSD, or if you have enabled write caching in the device's properties.

What is the difference in handling flash drives between Windows, macOS, and Linux?

Windows generally allows for hot-swapping of flash drives without ejecting them first, unless specific settings have been changed. In contrast, macOS and Linux require users to eject the device before disconnecting to prevent data corruption or damage to the device.

Why is it important to consider the type of storage device when deciding whether to eject before disconnecting?

Different storage devices have different mechanisms for ensuring data integrity when power is removed. Hard drives, for example, have a mechanism to park the read/write head safely, while SSDs and flash drives do not have such a mechanism and are less susceptible to damage from sudden power loss.

What is the purpose of the 'Write caching policy' in Windows device properties?

The 'Write caching policy' in Windows device properties allows the system to use the device's cache to improve performance. However, when this policy is enabled, it is important to use the 'Safely Remove Hardware' option before disconnecting the device to ensure that all cached data is written to the storage device.

What is the 'Quick Removal' policy in Windows, and when should it be used?

The 'Quick Removal' policy in Windows is a setting that allows for the immediate disconnection of a storage device without using the 'Safely Remove Hardware' option. It should be used when the device does not have write caching enabled and when it is not actively being used or accessed by the system.

How can you check if your storage device supports 'write caching' in Windows?

You can check if your storage device supports 'write caching' by going to the device properties in Windows, navigating to the 'Policies' tab, and looking for the 'Write caching policy' or 'Removal Policy' settings.

What is the impact of using the 'Better Performance' policy on a storage device?

Using the 'Better Performance' policy enables write caching on the device, which can improve system performance. However, it also requires that the 'Safely Remove Hardware' option be used before disconnecting the device to prevent data loss or corruption.

What precautions should be taken when using an external hard drive or SSD with Windows?

When using an external hard drive or SSD with Windows, you should ensure that the device is not in use (no files are open or being written to) and that you have either enabled the 'Quick Removal' policy or are using the 'Safely Remove Hardware' option before disconnecting.

How can you tell if a storage device is in use and should not be disconnected without ejecting first?

A storage device is in use if files are open or being written to on the device. You can check this by looking at open applications and ensuring that no files from the storage device are open. Additionally, Windows may prompt you if a file is in use and cannot be safely removed.

What are the potential risks of not ejecting a storage device properly before disconnecting?

Not ejecting a storage device properly before disconnecting can lead to data corruption, loss of unsaved changes, or even physical damage to the device, especially if it is an external hard drive with moving parts.
