Is it possible to run multiple instances of Wdckit.exe simultaneously?”

It is possible to run multiple instances of wdckit.exe in separate Command Prompt windows, each targeting a different WD SATA 512e non-RAID hard drive. The Windows 10 Pro 64-bit operating system and Intel SATA chipset support concurrent access to multiple drives, so the system itself won’t prevent this. However, whether wdckit.exe is designed to handle simultaneous execution safely is uncertain.

The tool performs low-level operations like formatting and changing block size from 512-byte to 4096-byte sectors, which typically require exclusive access to each drive. If more than one instance tries to access hardware resources at the same time, it may cause conflicts, failures, or even data loss. Without official documentation confirming that wdckit.exe supports concurrent operations, it’s better to assume it does not.

To avoid problems, run one instance at a time. If you want to streamline the process, use a batch script to automate the commands in sequence. This approach ensures each drive is processed safely without risking interference from another active session.
