Windows 7 Windows 7 Enterprise 64 bit - Disk 0 Partition 2 suddenly missing

It seems like you are facing an issue with your D drive disappearing in Windows Explorer. This can be a concerning situation, especially if you had data stored on that drive. The screenshot you provided suggests that the D drive is showing as a RAW partition, which means that the file system on the partition is unrecognized by Windows. Here are a few steps you can take to try to resolve this issue and retrieve your data from the previous D drive: 1. Check Disk Management: Since you've already checked Disk Management, you can try to assign a new drive letter to the RAW partition. This might make it accessible in Windows Explorer again. 2. Use Data Recovery Software: If assigning a new drive letter doesn't work, you can try using data recovery software to attempt to recover your files from the RAW partition. There are many data recovery tools available that can help in such situations. 3. Avoid Formatting: Do not format the RAW partition as this might erase your data permanently. It's essential to try to recover the data before considering any formatting options. 4. Consult IT Support: If the data on the D drive is critical and you are unable to recover it using simple methods, it might be worthwhile to contact your IT support team or a data recovery specialist for assistance. 5. Backup Important Data: In the future, it's always a good practice to regularly back up your important data to prevent data loss in situations like these. If you have any further questions or need more detailed guidance on data recovery options, feel free to ask.
