I work in technical support and received a company laptop after a user downloaded a trojan. The malware was removed, but the previous technician suspected the operating system had been damaged. I used the built-in Windows reset option, which reinstalled Windows 10, then upgraded the machine to Windows 11 and installed the available updates. When I try to enable BitLocker, the process begins loading but fails with the message: "A device attached to the system is not functioning." Could this indicate a corrupted or failing drive? I have not performed any hardware diagnostics yet, and I am looking for recommendations on what to check before reinstalling Windows from scratch.

Before assuming the drive is bad, run the laptop manufacturer’s hardware diagnostics, especially the SSD or hard-drive test. You can also check the drive’s SMART health data and review Event Viewer for storage or disk errors. CHKDSK can find filesystem problems, but it is not a complete test of the physical drive. Since the built-in reset may leave problems behind, a clean Windows 11 installation would also be a sensible next step after backing up anything needed.
A clean installation is preferable here, particularly because the machine previously had malware and the operating system was already suspected of being damaged. The built-in reset does not always produce a truly clean result. After reinstalling and updating Windows 11, confirm that TPM is enabled and working, check the disk health, and then try enabling BitLocker again. If it still fails, investigate the storage controller, firmware, TPM, and drive hardware rather than focusing only on the Windows installation.
Our standard setup uses Windows’ built-in BitLocker, so I’ll keep that approach. I’ll check the TPM and drive diagnostics and then perform a clean Windows 11 install if necessary.
The reset was done through the standard Windows recovery options. I’ll run the manufacturer’s diagnostics first, then try a clean Windows 11 installation if the hardware checks out.
