1, minimize the related software (related to stored files) that automatically runs when the computer is turned on, such as fast broadcast and thunder. In case of occupation.
2. After deleting files, clean the garbage collection box, and then delete the mobile hard disk.
3. Right-click to delete it safely. If it cannot be deleted safely, please delete it safely twice in a row.
4. Last resort: It is safest to restart the computer and then delete it.
5. External regulated power supply is more conducive to protecting the mobile hard disk and prolonging its service life.
Question 2: How to unplug the mobile hard disk is the safest way? When plugging and unplugging a mobile device, it depends on whether the data in the disk is being read, and whether the indicator light on the disk flashes on the USB flash drive. If it doesn't flash, it can basically be pulled out directly with all file windows closed. Just like the mobile hard disk, if the disk is not loaded with program files or reading data, it can be pulled out directly. . . Everything is safe. . . Never * * * when reading the data in the mobile device, it will easily lead to the end of the mobile device. . .
Problem 3: The removable hard disk cannot be safely unplugged. Usually Windows systems are optimized for USB storage, that is, for quick deletion, so as long as there is no reading or writing operation, you can directly unplug the USB connection.
If you want to solve the current problem, it may be that your Win7 program has other connections with your USB storage device, so it takes time to disconnect the current background operation when you issue the disconnect command. If you have other questions, you can ask me. My account number is my QQ number, and my mobile phone number is also on QQ. If I have a diploma, I will try my best to help you solve it at any time. I'm honored to help.
Question 4: If the mobile hard disk can't be pulled out safely when it is plugged into the computer, you can cancel the safe pulling out, or you can end the explorer process in the task manager and run explorer in a new task.
Question 5: Why can't my mobile hard disk be taken out safely when it is pulled out? The author found that when the system loads the hardware driver of the flash drive, it will automatically run the system file rundll32.exe. If this process is closed, the flash drive can be safely removed. The method is as follows: firstly, do not read or write the programs running on the closed U disk, and then unplug or eject the hardware, which can greatly increase the possibility of data not being lost or damaged. Then right-click the taskbar and select the task manager, or press Ctrl+Alt+Del(Windows NT/2000 users need to select the task manager again. ) The Task Manager window will appear and click the Processes tab. Look for rundll32.exe processes in the image name (if there are multiple rundll32.exe processes, just close them all. ), select the rundll32.exe process, and then click End Process. A warning from Task Manager will pop up. At this point, in order to let the user decide whether to close the process, click Yes to close the rundll32.exe process. But in order to ensure foolproof, there is one last way-turn off the computer first, and then safely pull out the USB flash drive after the indicator light goes out; If there is no flash drive with indicator light, it can be safely pulled out after the computer power indicator light is turned off and extinguished. Both of the above methods have happened. The universal volume device cannot be stopped now. Please stop the device later. Is there any way to prevent this problem? The answer is yes! Open my computer and select your flash drive. Right-click and select Properties, and the Removable Disk (H:) property will pop up (the drive letters here are arranged according to the partition of the operating system hard disk and the partition of the optical drive. E.g., disk H.) window, click the hardware tab. Select the flash drives used by all disk drives (Note: Don't make a mistake, there will be hard disks, floppy disks, optical drives, virtual optical drives and other devices. ), after selection, click Properties. The Flash Disk Name property opens and the Policy tab is selected. At this time, users can make choices according to their own needs: if users choose to optimize for quick deletion, at this time, the speed of reading and writing with the flash drive will decrease, but when users dial the flash drive directly, the data on the flash drive will not be lost or damaged. If the user chooses optimization to improve the performance, the read-write performance of the optimized USB flash drive is used at this time, but if the user dials the USB flash drive directly, the data of the USB flash drive may be damaged or lost. After selecting, click OK. How's it going? After reading it, do you feel that there are so many technologies in a small USB flash drive? Indeed, as long as you put your heart into it, you will find more miracles!
Question 6: Why can't the mobile hard disk be pulled out safely?
When using a u *** device (U disk or mobile hard disk) under xp, sometimes I will be prompted: You can't disable the universal volume ... What should I do? What if I can't stop and dare not pull it out? It happened that I met this problem again today. According to my experience, let's talk about several solutions.
1. Confirm that the data replication between the u *** device and the host has stopped and that the data is still being transmitted. Of course it can't stop.
2. Sometimes the explorer.exe process often causes the u *** device to be unable to delete, and the files and folders cannot be deleted. The solution is to open the process list in the task manager, close explorer.exe (the system interface will be empty at this time), then add a new task explorer.exe (interface recovery), and finally try to delete the u *** device. This method is the most commonly used, and this is how I solved it today.
3. Sometimes, some programs are accessing files on the USB flash drive or mobile hard disk. For example, a xxx player is playing a xxxx movie on the mobile hard disk, and the player has not been turned off, so of course, the mobile hard disk cannot be deleted. Sometimes, although the player is off, I don't know that there is something wrong with the string. The process of the player is still in the task manager, and it can be deleted when it stops. Not only the player, but also other xxxxx programs. For example, if you use qq to transfer files, you can't delete the USB flash drive immediately without closing the QQ dialog box after the transfer. If closing the dialog box doesn't solve the problem, close QQ.
4. If there is really no way, just restart it, and then you can delete it.
Radical method:
Right-click My Computer-Properties-Hardware-Device Manager, then double-click the disk drive, and then double-click your mobile hard disk or mp3, which is the kind with USB device. Select the Policy tab, select Optimize for Quick Delete, and then click OK. You can pull it directly in the future
There seems to be a USB interface in the control panel, which means you can dial USB control directly from the computer without clicking "safely delete hardware" in the system tray, but there is something wrong with this setting.
This method will create the illusion of "secondary transmission", which is actually to change the file into background cache transmission. In other words, when you see that the transfer is complete, the file is actually still being transferred. At this time, you can't disconnect the u *** device. If you forcibly disconnect, you will find that the file is not completely copied.
Danger: after this modification, it is impossible to correctly judge whether the file is really transmitted, but it brings trouble and the speed is not improved. Moreover, because it is impossible to judge the completion time of transmission, it is easy to disconnect the device when the files are not completely transmitted, which may lead to the loss of all files.
However, the reason why windows won't unplug is because the system has always misjudged that the transmission is not completed, so it can be used as a transitional method to artificially judge whether the hard disk stops running.
The complete solution is to install the latest motherboard driver or Intel official inf file, which can be found on Intel's website. If your motherboard is an Intel chipset, you can try it.
Question 7: Why is the mobile hard disk still running after I heard that the 360U disk assistant safely pulled out my mobile hard disk? You can pull it out. No problem.
As long as it pops out, the head retracts, but the disk is still spinning.
Do not move the hard disk at this time. It's best to unplug the USB one or two minutes before moving the hard disk.
Question 8: Will it affect if the newly bought mobile hard disk is directly unplugged after use? I won't. Take it easy. I also played directly several times. Once or twice, no problem. There was an error in making that sound. Just like a computer, it sometimes beeps when something goes wrong. Don't worry about storage, but it's best not to be direct. This is not good for your health.
Question 9: How to safely remove the mobile hard disk from the computer * * * This is a question of how to safely delete the hardware.
You safely deleted the hardware by right-clicking, so your current problem arises. There are many choices, but you don't know which one to delete. It's actually quite simple. You need to know the drive letter you use on the mobile hard disk so that you can delete it after it is safely deleted. (Drive letter: drive C, drive D, drive E, etc. on the computer. These are the drive letters. For example, your original computer only has three drive letters, namely C, D and E. Suppose your mobile hard disk is divided into two drives (with two drive letters), then the drive letters of your mobile hard disk will be displayed as "F" and "G" in the computer.
In fact, the above methods of safe deletion are not easy to use. The other is left-click deletion. This method is very easy to use, it will not display the original drive letter of the computer, and no matter how many drives your mobile hard disk is divided into, it will be classified as one line when deleted. You can safely delete the entire mobile hard disk with one click. (You can try to find out)
Therefore, it is suggested to delete the left key.
Question 10: What happens when the removable hard disk cannot be safely deleted and then unplugged? I don't know about your system, but I also have something to do in Win7. When the mobile hard disk is safely deleted, a window will pop up saying, "This device is in use. Please close all programs or windows that may use this device. Then try again. Occasionally, as long as you are not reading or writing, it is not a big problem to pull it out directly.
* * * Tell you a once-and-for-all method to avoid the damage of mobile hard disk caused by direct plugging and unplugging in the future: (Take Win7 as an example. XP is almost the same) (xyz58 19 original reply, welcome to copy)
Right-click to move the drive letter of the hard disk > Properties > Hardware >; Select mobile hard disk > Properties > General > Change Settings > Policy > Select OK to delete quickly. You can plug and unplug the mobile hard disk in the future without using safe deletion hardware, but you should avoid forcibly plugging and unplugging when reading and writing data, which should be paid attention to at any time and under any settings!
