My Lenovo laptop got hot while I was gaming, then crashed with a blue-screen error and restarted. Windows still runs normally from the SSD, but the HDD no longer appears in File Explorer. It does show up in Disk Management, though trying to initialize it produces a "Data error (cyclic redundancy check)" message. The drive contains important files I'd like to recover. Should I try any troubleshooting steps, or could initialization and recovery software make the damage worse?

If the drive is still readable in any way, copy the most important files immediately to another disk. Otherwise, leave it disconnected and replace it. This is also a good reminder to keep important files in at least two separate backup locations.
The crash may have been caused by the HDD failing rather than the BSOD causing the failure. If the data matters, avoid repeatedly powering the drive on, running repair tools, or using recovery software directly on it. A specialist can usually tell you the likely recovery cost before proceeding.
Stop trying to initialize or format the drive. A CRC error can indicate serious read or hardware problems, and further attempts may reduce the amount of data a professional can recover. Disconnect the HDD and contact a reputable data-recovery service for a diagnosis and quote.
You can inspect the Windows crash logs or minidump files to investigate the original blue screen, but that won’t repair the HDD or recover its contents. The CRC error and disappearing drive point more toward a disk or connection problem than a normal Windows configuration issue.
