If your hard drive is listed in disk management then only it will be detected by Stellar Data Recovery Professional software. If your hard drive is not displayed in disk management then it indicates that your hard drive is physically damaged. You can be sure about physical damage if it is making clicking or grinding sound. Please note that in case of data loss due to physical damage, no software can help you to recover the inaccessible data.
It is advised that in case of physical damage, DO NOT attempt data recovery on your own or through inexperienced technicians. It will lead to further damage of your hard drive, rendering it unusable for physical data recovery services at data recovery labs. Please send us your contact details with description of exact problem at support@stellarinfo.com so that Stellar Data Recovery Experts can speak to you to provide more details of physical recovery process of your hard drive.
