The old hard disk is not responding after the cable is connected.
The old hard drive did not respond after the cable was connected. This could be caused by the following reasons: 1. ** Power supply problem **: - If it was a 3.5-inch mechanical hard disk or a desktop optical drive, it might require a 12V power supply, and it would not work properly with USB power supply alone. Generally, the drive current of a solid state hard disk or a notebook hard disk was less than 1A, and it could be plugged and played with a 5V 2A power supply of USB3.0. However, if the notebook hard disk could not be used in the power cable and the solid state hard disk could be used, it could also be a power supply problem. - If there was a slight cracking sound, it was mostly due to a lack of power. You can try to connect the USB directly to the port on the back of the computer (on the motherboards), because the power supply of the front USB port may not be as strong as the port on the motherboards, or check if you need to connect an additional power source. 2. ** Connection problem **: - USB port malfunction or poor contact may cause the hard disk to not respond. Check whether the USB port of the patch cord is plugged in properly or damaged. - There may be problems with the patch cord itself. For example, an IDE-to-USB cable may not be able to drive a large capacity hard disk, or the patch cord may not be compatible with the hard disk. 3. ** Driver Problem **: - If it was under the Win98/2000 system, a driver might need to be installed. In the XP system and above, there was usually no need to drive the drive line, but there were special circumstances. If the driver is not installed or installed incorrectly, you may need to install the corresponding driver, such as the USB 2.0 driver. 4. ** Other questions **: - If it is a specific device (such as a Canon device connected to a hard disk), you may need to install your own software to read it. You can download and install the corresponding software through the random CD or the official website. Read more exciting novels for free
The hard disk is connected to the power source and runs repeatedly
The repeated operation of the hard disk after it was connected to the power source could be caused by a variety of reasons: 1. ** Memory factor **: If the memory is too small, the hard disk may be swapped too frequently, causing the hard disk to run repeatedly. 2. ** Too many disk fragments **: When there are too many disk fragments, you need to defragment them. This may happen if you don't defragment them. 3. ** Poisoning or Trojans **: Virus and Trojans in the computer are the more common possible causes. 4. ** Power supply problem **: For ordinary computer hard disks, if the power supply of the power charger is insufficient (for example, when an ordinary computer hard disk starts up, the instantaneous current may reach 2 amperes or even higher. If the power supply cannot provide enough current), it may cause the hard disk to work abnormally and repeatedly. 5. ** Hard disk problems **: For example, the hard disk has bad sectors. A hard disk that is used for a long time as a consumable may have bad sectors, which will affect the normal operation of the hard disk and cause it to run repeatedly. In response to this situation, the following measures could be considered: 1. Check if the memory is too small and upgrade it if necessary. 2. Defragment the disk. 3. Use an anti-virus software to carry out a comprehensive anti-virus. If one anti-virus software doesn't work, you can try other anti-virus software, or even tools under the dos, which may be more thorough. 4. Check if the power supply can provide enough current. If you suspect that there is a problem with the power supply, try to replace it with a suitable power supply. 5. For the hard disk bad track problem, you can connect the hard disk to a computer that is normally powered on, select the USB drive to boot through the computer boot, and use the hard disk repair tool in the hardware detection scan to detect and repair, but note that not all bad tracks can be repaired. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What should I do if the data cable of the mobile hard disk is changed and there is no response?
If the external hard drive still does not respond after changing the data cable, you can try the following operations: 1. Check the USB port: Make sure the USB port connected to the portable hard drive is working properly. You can try connecting it to another USB port on the computer, or connect it to the USB port of another computer for testing. 2. Check the power supply of the mobile hard disk: If the mobile hard disk needs an external power supply, please make sure that the power supply is working normally. 3. Check the driver: In the Windows system, right-click "Computer" or "This computer", select "Management", and check whether the disk drive has a yellow warning sign in the "Device Manager". If there is, it means that there may be a problem with the driver. You can try updating or reinstalling the driver. 4. Check for viruses or malicious software: Use anti-virus software to scan the external hard drive to ensure that it is not infected. 5. Use the built-in tools of the operating system to check and fix file system errors. 6. Use professional data recovery software: If you suspect that the data is lost or the file system is damaged, you can use professional data recovery software to repair it. Some software can perform disk inspection and repair operations. 7. Checking for hardware problems: Loose interface cable of the mobile hard disk, hard disk power supply problems, and other hardware faults may also cause the hard disk to not respond. You can try to replace the interface cable or connect it to another computer to test to eliminate the possibility of hardware failure. If none of the above methods can solve the problem, you may need to recover the data and reformat the hard drive. Please be careful with this step, because reformat will delete all data. If the problem still cannot be solved, it may be a hardware failure. It is recommended to contact a professional data recovery service or contact the technical support of the mobile hard disk manufacturer for help. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
DSLR hard disk
As for the DSLR and the computer hard disk, during the DSLR photography process, the computer hard disk could be used to store the shooting materials. From the information provided, it could be seen that the capacity and speed of the hard disk would affect the work efficiency when processing the materials taken by the DSLR camera. If the hard disk capacity is insufficient, such as when you want to use the stack effect to replace the light reduction mirror effect, there may be no temporary space to operate because the hard disk is full (Ref. 2). For the storage of the materials for the single-lens reflex camera, the capacity of the solid-state disk should not be too large. It should be more focused on speed, reliability, and size. For large-capacity material backup, it is more cost-effective and relatively reliable to choose a mechanical hard disk (Ref. 6). In terms of data transmission, different ports and types of hard drives had different speeds. For example, the maximum speed of a 2.5-inch mechanical hard drive in a USB 3.0 hard drive case was 200MB/s. A small capacity could easily reach 400MB/s when placed in a solid state drive, and a large capacity and high quality could reach 460MB/s (reference 7). This would affect the efficiency of transferring the DSLR footage between computer hard drives. When processing large footage such as 8K video (120mb data per second, bit rate of about 1000mb/s), the hard drive speed was required to be higher (reference 7). At the same time, there were also different specifications of devices such as hard disk boxes with 10 Gbit/s interface speeds to meet different material transmission needs. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The old man is breathing but not responding.
If the old man was breathing but not responding, the situation would be more complicated. First of all, he had to observe whether the frequency and rhythm of breathing were normal. If his breathing was shallow and slow, it might be a sign that his spontaneous breathing was about to stop. He might die at any time due to the stop of breathing and circulation. If the old man had severe heart and lung failure and was in a coma, even if his breathing frequency and rhythm were temporarily normal, he might not be able to produce phlegm or eat, which might cause complications such as lung infection, malnutrition, bedsores, and so on. This could lead to respiratory failure, circulatory failure, and death. In addition, some elderly people may have underlying diseases that affect the respiratory system and are slow to respond to oxygen deficiency. Even if there is no obvious response, they may already be in a state of oxygen deficiency. Some elderly people may have this condition due to heart or lung disease. For example, patients with chronic obstruction of lung disease may develop respiratory failure. The symptoms may not be specific and difficult to distinguish from the usual symptoms. In this case, medical examination is needed, such as an artery blood gas analysis to determine the cause. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Is the data cable connected to the phone camera?
Some data cables can be connected to the phone and camera. For example, if the data cable connection of the Sony-camera does not respond, you can set up the phone and camera before inserting the cable. The USB mode of the camera should be switched to "MMT" or "Computer Remote Control". If the phone and camera are both Type C ports, try to swap the data cable and reconnect. During the filming process, the camera and the phone were frequently disconnected. It might be because the connection cable was unstable, so it was necessary to change the data cable with a tighter interface. You can open the Android version of the APP and buy it according to the camera model and phone interface in the data cable of My Xiangxiang Mall. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The data cable cannot be connected to the DSLR.
If the data cable cannot be connected to the DSLR camera, there may be several reasons: 1. There were too many photos in the camera's memory card, and it would take some time for the computer to read them. However, if there was no reaction after a few minutes, there might be other problems. 2. If the USB port failed, he could try another USB port. For example, the desktop should not be connected to the front panel port, but plugged into the USB port on the back of the computer. 3. The USB cable was faulty. He tried to change the USB cable. 4. The USB cable is too long, or the use of a poor quality USB hub or a socket will cause the reading of data to be slow or even non-existent. It is recommended to use a short USB cable of about 50cm. 5. The computer cannot correctly identify the camera that is plugged in. You need to install the driver (if there is one) from the CD that comes with the camera in the computer. The installation method can be carried out according to the installation instructions and prompt steps. You must install the driver first before inserting the camera data cable. 6. If it can recognize but cannot operate, it may be a driver error or a hardware conflict. However, before unplugged the camera, he opened the Device Manager (right-click "My Computer" → "Attributes" → "hardware" → Device Manager), found the "Universal serial bus controller", and clicked the + sign in front to see which of the several USB device options was open? No! number. If there is, delete it and try reinstalling it after uninstalling the original driver (scan to detect hardware changes and reload the driver) or restart the computer. 7. Check the Control Panel → Administrative Tools → Services to see if the related services such as "plug and play" and "windows image usage" are disabled or set to manual. If so, they should be set to automatic. 8. The computer could only recognize the USB device after the DSLR camera was turned on. It might be because it was not turned on. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Can there be electricity if the cable is connected in reverse?
Is the camera cable connected in series or in parallel?
The series and parallel connection of the camera lines had their own characteristics, and it was not easy to say which was better. In the series connection method, the equipment was connected in turn, and there might be a risk that a fault would affect the operation of subsequent equipment. However, the line was relatively simple, and the cost of the cable might be lower. In the parallel connection mode, each device was connected to a power source or signal source independently. A device failure usually would not affect the normal operation of other devices, but this method may require more wire materials, which was relatively complicated. If the stability requirements are high and the budget allows, parallel connection may be a better choice; if the cost is considered and there are countermeasures for the overall stability risk, series connection can also meet the requirements. For example, in some monitoring systems with high reliability requirements, such as the monitoring network of a bank, the parallel connection may be preferred; in some small and simple monitoring scenarios, the serial connection may be able to meet the requirements. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

External recording hard disk
There were a variety of products available for external recording hard disks. For example, the ATOMOS-related recorder could be used for external recording on a DSLR. For example, the ATOMOS-Ninja Ninja V recorder could be used for external recording on a DSLR 4K. There were different sets of accessories, including hard disk docks, Samsung hard drives, and other accessories. Also, the Hibis mini solid state hard drive case was a more cost-effective choice for recording videos and taking photos on the Pantheon G9M2 (belonging to the category of DSLR). In this way, the 256G high-speed double-sided SD card was more expensive to meet the needs of the camera to shoot videos, but the 1TL solid state hard drive and hard drive case could be solved for a total of more than 500 yuan. Its reading and writing speed could reach more than 1100 trillion per second to record videos, and there was no need to export the video from the memory card after recording. Directly insert the hard drive into the camera and record. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
