Running Dell diagnostics
is one way for you to check your computer hardware without any additional equipment and without destroying any data. The diagnostic tests can provide important information that is needed when talking to Dell's customer service personnel. However, some issues can arise when it comes to performing diagnostics on an encrypted hard drive.
Dell engineering has confirmed that DST/PSA/ePSA hard drive diagnostics can be performed on encrypted hard drives, even without an administrator password. While it is true that the data is inaccessible, the diagnostic can access areas on the hard drive that will allow them to test and store results. These diagnostics can also be performed on Bitlocker
