It's A Digital Disease!

Hello everyone,

Just wanted to share a small program I wrote that writes and verifies data on a raw disk device. It's designed to stress-test hard drives and SSDs by dividing the disk into sections, writing data in parallel using multiple worker threads, and verifying the written content for integrity.

I use it regularly to test brand-new disks before adding them to a production NAS — and it has already helped me catch a few defective drives.

Hope you find it useful too!
