Ethernet miner does not recognize hard disk

1. It depends on what brand of 7W Ethereum mining chassis is used. Some of them are very low. They soon get hot and crash. A better one, that is, McKenzie's, is a relatively good choice.

2. If the hard disk is not recognized, it means that there is a physical fault in the hard disk. In this case, if there is no important data on the hard disk, just replace it with a new one. If the data on the hard disk is very important, you need to contact a professional data recovery organization to extract the data. In this case, if you want to recover the data, it is very likely that you will open the disk to recover the data, because if the hard disk cannot recognize it, any software will not be able to operate.

[the reason why PE can't identify the hard disk]

1. The PE tool version is too low

it may be the problem of PE tool. For example, the PE tool version is too low, and the low version PE tool usually needs to switch the hard disk to ide mode to identify it

2. Incorrect setting of hard disk mode is the most common problem.

the two most common modes of hard disk are AHCI and IDE. Systems above win7 or SSDs use AHCI mode, while older PE tools use ide mode, so hard disk cannot be recognized when encountering PE, Users only need to reset the corresponding mode in the BIOS

3. Hard disk failure (including improper installation of hard disk and hardware failure of hard disk itself)

if the hard disk is not recognized in the BIOS, it may be because the cable is not connected properly ring the installation of the hard disk, or the hard disk is not installed properly, or the hard disk has failed

[solution for PE unable to identify hard disk]

1. You can switch the hard disk mode according to the PE version

2. If the hard disk can't be identified in the BIOS, can you replace it with a SATA serial port cable? If not, the hard disk itself may be broken, so it is recommended to replace the hard disk

The steps are as follows:

1. Principle explanation

in view of this phenomenon, it is most suitable to use the following troubleshooting in computer maintenance. Because, before the computer is no problem. Therefore, there is no need to replace the hardware or something. Simply, you can solve the problem by following the investigation. Let's take a look at the IDE settings of the hard disk in the BIOS before the repair. As shown in the figure, no detected is displayed

here is a detailed introction to the solution to the problem that the hard disk cannot be detected in the computer BIOS. Such a problem may be caused by the bad hard disk. Of course, it is not caused by other reasons. Jianyi will change this hard disk to another good computer and try to see if it can be used. You can also try the above solutions

5. The computer can't read the mobile hard disk. There are many possibilities. Use the elimination method to eliminate them one by one. First, try to replace the computer. If you still can't read them, you can judge that it's the fault of the mobile hard disk. The interface and data cable of the mobile hard disk box are relatively simple in structure, so the probability of damage is relatively small. You have the ready-made data cable and box to try, You can also open the box to take out the hard disk and find a desktop computer to pick it up. If you still can't identify it, it's the problem of the hard disk itself. The most common faults are irreparable, such as bad physical track and abnormal mechanical structure inside the hard disk. At this time, you should consider whether the hard disk has important data. If there is data, it's troublesome, The hardware problem can't be solved by itself. You can find 51recovery

6. What if the USB flash disk is broken and cannot be recognized? U-disk is a common information storage tool in our work, study and life. It is loved by people because of its large capacity, low price and small size. Therefore, U-disk has become an information carrier for some important information. However, e to long-time use, performance degradation or user misoperation, sometimes the U disk will lose or delete data by mistake. How can we recover the lost data? At this time, we must remember not to read and write again, in order to prevent the data from being covered and permanently lost, and use professional software to recover at the first time, because the shorter the time of data loss, the greater the possibility of recovery

at this time, there is almost no rescue operation that can be carried out through the computer system, so we must rely on professional data recovery software. Taking hi format data recovery master as an example, the operation steps of using professional software to recover data are as follows:
in the first step, log in to the official website of hi format data recovery master, download and install the software according to the steps

in the second step, insert the USB disk into the USB interface, and the software can automatically identify the USB disk. At this time, in the "scene mode", select the "USB disk / memory card recovery" function to scan the data of your own USB disk. The scanning time is determined by the amount of data information. At the same time, it is necessary to ensure the stable connection of the U disk in the scanning process in order to scan the data information completely and complete the recovery

in the third step, after scanning, find the data you want to restore in the scanning results, check and click restore. If there is too much information, you can also adjust the sorting method to find the data information you want to recover. It should be noted that when restoring a file, the restored file and the original storage path cannot be the same. This is to prevent the original data from being lost or some other errors

the above is about the U disk broken unrecognizable repair methods. The key to how to recover the lost data of USB flash disk is to stop reading and writing immediately to prevent the data from being covered or lost, and then seek the help of professional software. As mentioned in the article, hi format data recovery master is an expert data recovery software, which supports the data recovery of all kinds of storage devices such as the recovery station emptying file recovery, USB flash disk, memory card, etc, At the same time, it supports many functions such as fast scanning, deep scanning and so on. For users who are not familiar with computer operation, hi format data recovery master also provides a more simple "Wizard mode" for retrieval, and you can try the scanning function for free. Go and have a try!

7. This question is a bit interesting. If I guess correctly, it should be that there was a hard disk originally, and then another one was attached. Otherwise, how could there be system and disk management
if this is the case, the problem will be solved slowly. The main reasons are wrong jumper setting, wrong interface, insufficient power supply, unable to hang two hard disks, and the hard disk itself may be broken

the motherboard and hard disk are not compatible??? This is the first time I heard that there is something wrong with the hard disk interface of this motherboard

8. If you can't identify the hard disk, it depends on whether your hard disk is a SATA interface or nvmem point 2 interface. Some low-end CPUs of Intel and AMD do not support nvme hard disk with m-point-2 interface. But it has strong compatibility with hard disk of SATA interface. If the m-point-2 hard disk is not recognized by the motherboard, you can try it. Nvme adapter card is inserted into the graphics card interface. My computer realizes nvme hard disk recognition through the graphics card interface inserted into the adapter card.

9. The first symptom: the system can't find or recognize the hard disk after power on

this kind of situation leads to the system can't have the hard disk boot, even if we start the computer by other means, we can't find the hard disk. In fact, the solution to this situation is very simple, because up to now, I haven't heard of the compatibility problem between the hard disk and the motherboard. It is very likely that this kind of problem is on the connection between the hard disk and the motherboard. Therefore, I suggest you replace the connection between the hard disk and the motherboard, If it's not the problem of connection, then you can see whether the master-slave line on the hard disk is set correctly, and how to set the location of the master-slave jumper. Generally, there will be a prompt on the hard disk. According to your own needs, you can set the hard disk as the master disk or the slave disk to solve this kind of problem<

the second symptom: improper BIOS settings lead to problems with the hard disk

this kind of problem is generally not the responsibility of the user, because the current motherboard has the function of automatically detecting the type and brand of the hard disk, so it is usually not changed, However, some motherboards may have errors in identifying the type of hard disk when they are running, which will also cause the system to fail to boot from the hard disk
in addition, the BIOS of the motherboard can also set the normal, LBA, large and other working modes of the hard disk, which must be set according to the situation of the hard disk, otherwise other errors are likely to occur. The solution to this kind of situation is not difficult, as long as the BIOS instructions of the motherboard and the hard disk itself are set correctly

the third symptom: there is a main boot program, but the hard disk cannot be started

as we all know, the hard disk has a main boot area, in which the main boot program is stored. If there is a problem with the main boot program, then the system cannot be started from the hard disk, which is a very normal thing. It's not a very complicated thing to remove this fault, as long as you input the fdisk / MBR command in DOS mode. This is mainly because the fdisk command file itself contains a main boot program of the hard disk. Since Microsoft has thought of it, why not. From the current situation, there are many cases that the system can not guide the system correctly, but the common ones are basically mentioned in this article<

the fourth symptom: it can be recognized in the BIOS, but not in the system.

this problem often occurs when a new hard disk is added to the computer. It can be seen in the BIOS, but it can't be seen in the disk management and device manager of the system. In addition to the common jumper and setting the master-slave disk, another point is often ignored, That is the property of "ide ATA / ATAPI controller" in the device manager - "primary IDC channel" or "secondary IDC channel" (which port you plug the hard disk into), and "advanced settings" - device 0 - device type. If it is "None", please change it to "automatic detection", and then restart it.
