Kindly note that the rating will fluctuate over time, so the rating you see on our website may not be the same as the rating on the current Trustpilot. Regarding the warning at the top of this page, we've contacted Trustpilot and appealed to it, and they are still investigating and monitoring it and promise for us to solve it as earlier as possible. ![]() In line with your concerns, we'd like to explain them one by one in more detail, and hopefully, it makes things clear and help you. Thanks for taking the time to write a review for us. Reply from Wondershare Recoverit May 25, 2023 Really appreciate a lot for your time and patience! To address your concern, our support will investigate this matter further and then keep you updated as earlier as possible. ![]() Knowing you were encountering a problem, we desperately hope to fix it, and this is the reason our support might invite you to provide more details (like a screenshot showing the problem and log files, etc.) for troubleshooting, and this was also the reason we didn't process a refund for you in the first place. We accept a refund request if the customer encounters a technical or compatible issue that is unable to be solved within 7 days. In case you might need help urgently next time, we sincerely invite you to submit a callback request from the following link and we'll call back in your time zone from 9 am - 10 pm. We'll keep improving and do our best to provide a better and better experience for each user. I understand that it is very important for users to get help timely when he/she has trouble using the product. It might be caused by the overwhelming phone calls at that time. We are sorry to hear that you didn't get in touch with our phone support. If the particles cannot be written, they will be marked as unavailable and become a bad sector, with no more data being written.Reply from Wondershare Recoverit Updated Jun 30, 2023 Before writing data into the particles, the state of the particles will be checked in advance. The flash memory particles of SSD have a life limit for writing data. These advantages make the work of SSD more stable. In contrast, the likelihood of physical bad sectors in SSD is smaller than in HDD because SSD is designed to withstand stronger vibrations and does not require heads to write and read data. As it turns out, the probability of logical bad sectors in SSD is even greater than in HDD. So that explains bad sectors for an HDD, but what about an SSD that doesn’t have platters or heads for accessing data. Using disks under extreme conditions, such as high temperature, dust, ultrasound, and violent vibration, can destroy platters or disks and cause bad sectors.All these can cause damage to the operation of platters and heads. The poor working condition of disks causes bad sectors, such as unstable voltage, and overshoot current.Bad usage habits can result in bad sectors on disks, such as frequent collisions, improper software operation, excessive I/O for a long time, forced shutdown, etc.But if users reset the disk firmware, the bad sectors will be exposed. Usually, these manufacturers will hide this secret during low-level formatting. Due to technical issues, disks may have bad sectors before leaving the factory. These structures can verify each sector’s positioning, data synchronization, and correctness checking. ![]() In this way, the reading of data can be realized.Īnother component of a disk is sectors, the logical structure of which include gap, sync, address mark, data, and ECC. Based on changes in the electric field, the polarity of the magnetic media on the platter can be identified. After that, the disk can generate an induced electric field in the disk coil due to the head passing over the surface of platters. The changes in polarity are generated by the current change of the head coil, which is only 0.1~0.3 microns to the surface of the magnetic media. Hence, the cooperation between platters and heads realizes the addressing of sectors.Īs for the data writing process, it occurs when changing the polarity of the magnetic media on the platter. The motor shaft drives the platters to rotate, and the head can move in the radial direction. The polarity of magnetic media (N/S) is used for recording data storage. They are made from hard metal materials and magnetic media. The platters of HDD are what carry the data storage. ![]()
