Often, we can. The overall process is to install a new hard disk on the server and then attempt to mount the old drive so that we can restore the data from it. There are times when a drive cannot be mounted or read at all, and no data can be extracted from it. In these cases, when the data is valuable enough, you may be able to have the data center send the physical disk to a data recovery specialist who may be able to assist.  If you do not have an adequate backup plan in place, please consider using our Linux Server Backup, which can be purchased as an add-on when you buy management.
