My Lenovo laptop became hot while I was playing a game, then crashed with a blue-screen error and restarted. Windows still sees my SSD, but the HDD appears to be missing from normal use. The HDD is visible in Disk Management, but trying to initialize it produces a "Data error (cyclic redundancy check)" message. There is important data on the drive, so I want to recover it without making the situation worse. What should I do next, and are there any safe recovery options?

The crash may have been caused by the HDD failing rather than the BSOD causing the failure. If the drive is still accessible at all, copy the most important files immediately to another disk, but avoid repeatedly powering it on if it is making unusual noises or disconnecting. If the data matters, stop experimenting and have it assessed professionally.
If the drive appears as RAW or unallocated, treat that as a warning and don’t attempt initialization. Software recovery can sometimes help with logical damage, but with a CRC error it may also put extra stress on a physically failing disk. A recovery specialist can usually provide an estimate after inspection.
Once the data is recovered, replace the HDD and set up a backup system using another physical drive or cloud storage. Important files should exist in at least two separate locations; otherwise a single disk failure can make them effectively unrecoverable.
Don’t initialize, format, or run repair tools on the HDD. A CRC error often points to failing hardware or unreadable sectors, and writing to the drive can reduce the chances of recovery. Disconnect it and contact a reputable professional data-recovery service for a diagnosis and quote. Recovery can be expensive, but this is the safest approach if the files are valuable.
