Several troubleshooting methods discussed here require formatting your hard disk, resulting in data loss. However, you can recover a significant portion of your data using the chkdsk command or recovery software before applying the advanced fixes mentioned above. EaseUS Data Recovery Wizard, Recuva, and Disk Drill Data Recovery are the best recovery software to save lost data. Even if the software fails to get your information back, you can contact a hard drive data recovery service and extract your data from even the most severely-damaged drives. SalvageData, CBL Data Recovery, and Ontrack are some of the best data recovery services available.
