Definitely A. CheckDisk and others won't work on Linux.

I was unsure, but Badblocks makes sense. Other options are for Windows.

Badblocks? More like "Bad-at-hiding-the-bad-blocks!" This tool is a lifesaver for any Linux user.

CHKDSK? More like "CHK, this disk is toast!" Badblocks is the ultimate disk detective.

ScanDisk? More like "Scan for a working disk" amirite? Badblocks is the only way to keep your hard drive in tip-top shape.

I tried CheckDisk once, but it was like trying to find a needle in a haystack. Badblocks is the real MVP.

I’m a bit confused; I thought "ScanDisk" was a Windows tool too. Does "Badblocks" really work for Linux?

I practiced a similar question, and I believe "Badblocks" was the answer. It scans for bad sectors, right?

I feel like I've seen "CheckDisk" mentioned in Windows contexts, so that one doesn't seem right for Linux.

I'm a bit confused on this one. I know there are some disk checking utilities in Linux, but I'm not certain which one is used specifically for bad sectors. I'll have to think this through carefully.

Badblocks sounds familiar, I'm pretty sure that's the right answer. I'll mark that one down unless I can think of a better option.
