I'm sorry to hear that your desktop computer's hard drive has failed. The chances of data recovery depend on several factors, such as the severity of the failure and the steps taken to recover the data. It is not always possible to recover data from a failed hard drive, but there are professional data recovery services that may be able to help.
If you do decide to pursue data recovery services, it's important to choose a reputable provider with a track record of success in recovering data from failed hard drives. Prices for data recovery services can vary widely depending on the complexity of the recovery, the amount of data being recovered, and the provider's pricing structure. As a rough estimate, data recovery services can cost anywhere from a few hundred dollars to several thousand dollars.
In the meantime, if your computer is still under warranty or if you have a service plan with the manufacturer or a third-party provider, you may want to contact them to see if they can help with data recovery or offer a replacement for the failed hard drive. Additionally, if you have any important data that you need immediately, you may want to try recovering it yourself using data recovery software or by contacting a local computer repair shop for assistance.
