No matter brand the Server hard drive is
We can recover its data
●Server HDD cannot be recognized on the server (computer cannot recognize HDD)
●Data access is very slow (the data access speed of HDD is significantly slower than usual)
●The HDD makes sudden strange sounds (cluck or other abnormal sounds)
●The HDD fault warning light is on (the fault warning light is on)
●The HDD is offline (an HDD failure or array problem)
The processing method of the server HDD is similar to that of home HDD, which requires a mixed RAID technology for recovery. As the server HDD usually runs RAID, it is a double fault and check. Among numerous failures, there is only one situation that we suggest you try to recover by yourself, and we suggest you leave the remaining situations to a company specifically engaged in data recovery for processing (we will, in the paragraphs below, explain the reason why you should leave the remaining situations to a data recovery company, rather than try to solve them by yourself). The only one situation is that the HDD does not suffer hardware damage, such as careless deletion of data and no writing of any data, or careless formatting of the HDD, and then you can try to recover data with data recovery software. The commonly used data recovery software includes EasyRecovery, WiseRecovery and Disk Drill, and it is necessary to pay attention to and identify their advantages and disadvantages in use. Of course, before trying it out on your own, there are certain steps you must pay attention to, otherwise, data may not be recovered and your HDD may be further damaged. The first step is to make a complete copy of the HDD according to the current state to another HDD (not the copy and paste through Windows, but completely copy every byte of the HDD through software, which can be done only when the HDD does not suffer hardware damage). This step requires a writing protection device (Write Blocker), so as to prevent change of the data. Then you can use the data recovery software to recover the copied HDD, but the recovered data must not be put back to the original HDD. It is because, in this case, overwriting and recovering will occur simultaneously and the recovered data cannot be opened. So keep in mind the above steps. For anything you don’t understand, please feel free to contact us for details at any time, and we are willing to answer questions for each customer. But sometimes the data recovery software cannot solve all problems, and in most cases, you have to rely on data recovery engineers for analysis. For example, why the rescued data does not have directory or file name or not a byte of data can be rescued. At this point, you don't have to give up and you can contact us. We will try to rescue your important data.
If the HDD suffers hardware damage, and because there is no professional technology or equipment, you might truly make the HDD worse or the data lost forever through aimless attempts. For example, there is a bad sector on the HDD, but you use the data recovery software to scan the HDD, and then you will find the HDD is getting slower and slower, even a crash. This is because scanning is to read the information of each sector of the HDD. When it comes to the bad sector, it will get stuck and reading cannot continue. The magnetism of the HDD will become increasingly weaker due to continuous forced reading, and the number of bad sectors will increase. At this moment, it is quite usual that a friend or someone knowing much about computer will tell you to recover the bad sectors with special software. The result, of course, will be in vain. This is because the software doesn't fix the bad sectors at all but marks areas with bad sectors as no longer in use, and by that time, things are worse than they originally were. If you take the HDD to a professional data recovery company at this moment, the failure detected will be more serious than it initially was. Actually, if you want to recover the data from the HDD with bad sector failure, the data can be smoothly recovered with corresponding equipment support, with relatively low price and high degree of data integrity. But if you make forced reading, scanning and bad sector recovery on your own, the HDD will become more damaged, even the magnetic head used to read and write data might fail. Then the price will be high and data integrity will be reduced. In individual cases, the disk might be scratched, leading to serious data loss. In the past recovery cases, many users would constantly try to read the HDD on their own, which would have a great impact on the subsequent data recovery. It is therefore suggested that non-professionals should minimize aimless operation. There is only one chance for data recovery. Please make backup and find a professional data recovery company to help rescue your valuable information.
If the data in an HDD needs to be rescued in case of failure, the first thing to do is to find out whether the HDD failure is a logic failure or a hardware failure, which can be done through customer’s detailed description and detailed detection with professional devices. Commonly used professional devices include PC-3000, Data Compass, dust-free laboratory, microscope and oscilloscope. These professional devices and tools can help us accurately detect specific HDD failures without damaging the HDD. Moreover, the server HDD has its own unique storage interface, mainly SCSI and SAS, and its firmware is also different from that of the home HDD. It is necessary to solve these problems with corresponding technology, so that the original data of the HDD can be extracted normally and restored to the customer's needed data through analysis and reorganization. As a result, aimless operation will cause unnecessary damage to the HDD and affect HDD data salvation.
The point is that data recovery engineers of the Company not only have excellent data recovery technology, but have qualifications of Microsoft's MCSE, VMware's VCP, Linux's LPI, and CIFI (Computer Information Forensics Investigator), as well as over two-decade experience in information technology infrastructure. They are familiar with damages in large enterprise IT, such as servers, virtual systems, operating systems, file structure, directory area and data area. Thus, they may formulate corresponding solutions to reorganize the data. Only by combining various experiences can the best effect of data recovery be achieved.
