Brilliant. Whirring disk noise is nice touch. If AI generated this is what the AI revolution is all about. Can we get a cross platform screensaver?

Need this but for AI models. Sleep mode where they self prune and optimize overnight for their daily purpose.

I love this. I wanted the disk noise, and I got it. I will say that’s a lot faster than my drives were in the late 1990s though.

My computer's definitely gonna be faster after this.

Love the warning for using on a mobile device.

The sound killed me... :D

There's something satisfying about defragging that has been lost to time. Like oiling a squeaky engine

I love it. A couple notes: - This is about 10x a real defrag speed - WAAAY too fast - IIRC the "Data that will not be moved" was typically lumped at the beginning of the drive, not spread out all over.

Will need to degauss after this

What were the major filesystem technology improvements that made this redundant?

I need to set up a Windows 95 computer with a hard drive and stream the defragging online, complete with live audio.

bill gates, I want my time back!

When I was younger, my friends and I joked about making a "Disk Fragmenter" which would enumerate through every file on the disk and split them into non-contiguous clusters to make sure that the actuator arm on your platter-drive gets a PROPER WORKOUT TO FEEL THE BURN.

4 Drives, 5.5G total. Luxury! Per-drive individual sounds, and BSoD included. Nice touches, love it!

There is even a click noise when you idly tap the screen. As great as it is, way too fast.

It feels a little too defragmented to start. Typically it would be getting some bits from other parts of the drive and there would be a few (that many) bits it wouldn't move because they were the swap file and DOS boot system files.

I recall there being some techno-mysticism surrounding defragging regarding how often and when it was necessary, what it did and didn’t help, etc. I also remember the claim “Macs don’t need defragging” but I don’t know if HFS(+) was actually any less prone to fragmentation than FAT32 was. Companies like Symantec were happy to sell defragging tools to Mac users regardless.
