Windows 10 Bug That Can Corrupt Hard Drives

FTA: An example command that corrupts a drive is shown below

  cd c:\:$i30:$bitmap

So, ‘cd’ can trigger writes to a file system?

This also is a very scary bug as it allows a user level command to corrupt a disk.

If you remember the con\con bug this isn’t that surprising.

More discussion in this other thread which I didn't find when submitting this. [0]

It appears that the file system is not actually corrupted. The bug is just triggering a warning popup and a consistency check at the next boot. [1]

Thanks. Especially that second link seems very much more plausible in its analysis “This is probably a simple check assertion somewhere which is seeing unexpected data passing through a call”

If you write a file system every bug can destroy years of data, silently, so “better be safe then sorry” should be a poster hanging on every wall, so even a simple directory traversal, upon seeing a “this normally shouldn’t happen” event, should raise a few flags.
