defuser Posted December 24, 2025 Posted December 24, 2025 (edited) As you know, the speed of ScanDisk under Windows 9x depends on the intensity of mouse movement. I made a short recording demonstrating this effect: As you can see in the recording, the speed of the scan increases significantly when you move the mouse. The question is, is it possible to fix this behavior so that the scan always runs at maximum speed and is not affected by mouse movement? Thank you. Edited December 24, 2025 by defuser

I don't have Windows ME on bare metal right now to test this. However, on Windows ME running in Virtual PC, the behavior of "SCANDSKW" is similar, and the effect is quite good: This provides a clear demonstration of the change in write speed during disk surface scanning, where: "1" - when the SCANDSKW window is in the background; "2" - when the SCANDSKW window is active; "3" - when intensive mouse movements occur above the active SCANDSKW window.

MERCURY127 Posted January 8 Posted January 8 (edited) i think, it is just stupid typo in code: they want "eat less cpu time if user is active", but get reversed. Edited January 8 by MERCURY127 1

Thank you. it would be great to have a software that mimics mouse movement by just a keyboard shortcut, and that is compatible for 98/ME... With that, it can complete faster... 1

With that, it can complete faster... That's a good idea. I'll give it a try, but if I can't find a complete solution to this problem (and I still haven't given up hope), there's not much else I can do. I already have the "RECORDER" tool from Windows 3x, which allows me to record and play back any actions with a high level of accuracy (including mouse movements) and reproduce them in the same sequence. It works well in Windows 98 (although I'm not sure why Microsoft didn't include this useful tool in Windows 9x and later versions). About once every few days, I check RAMDRV64, which is used by several programs that are writing to it at the same time, causing occasional cross-writes that are successfully corrected by ScanDisk (restoring lost free space). Over time, these "mouse movements" become somewhat tedious. Therefore, it is important to me. Thank you!
