Can CHKDSK Corrupt Files?

✴️ If CHKDSK freezes when you run it, you may have a problem with your files or hard disk, but CHKDSK didn't cause them.

✴️ CHKDSK and file corruption
CHKDSK does not cause file corruption, but it can expose pre-existing problems on a hard disk. The best prevention is to back up regularly so that when, not if, problems occur, you won’t lose any data and will be minimally inconvenienced.

This is an excellent and nuisanced response. I was in disagreement early in the video BUT his point regarding what truly causes a problem verses changing how an pre-existing problem manifests is brilliant.

Please l lost 300gb of files through chkdsk but the drive still shows that ive used the space in the disc but doesn’t show my files, please is there an easy way of recovering my files

[danbromberg]

Nicely discussed but I never read an explanation describing what chkdsk does to correct a corrupt system file. Does it actually go out to the MS site to fetch a replacement?

I have a 64 GB SD card from my phone and I did check this command and it would not recover the corrupted files it shows that the files were hidden I don't know if it was a virus that causes the issue because I used to download lots of videos and stuff I don't know if that was the issue but I was wondering can you help me because I have lots of old videos of horses and photos and if you can help me by the way I love all your videos they all help me work on computers maybe you could do a video talking about how to recover files that are not coming on your SD card

[miswarbio]

It's is safe to access the drive during CHDSK /r?

@6:40 "SSDs, for example, wear out"
Technically that is true. But you will never wear out your SSD, even if you go out of your way to wear it out.

One type of crypt-o mining is named Chia.
Chia uses a temp storage device to perform its operations. That process involves never-ending reads, writes, and deletions (deletions are a form a write operation).

There are countless people, globally, that are mining via Chia. With few exceptions, they use NVMe drives (SSD drives) as their temp storage for the process. Those folks have been running their Chia operations for 18+ months, 24 hours a day, every day. Yet, no one has reported that they wore out their SSD. Not a single person, based on the Chia forums.

SSDs have a TBW (terabytes written) value, specified by the manufacturer. The SSD keeps track of how many bytes of data you have written to the SSD. If you exceed the TBW value, then you end your warranty. And if you run the manufacturer's software that checks the health of the SSD, it will claim that the SSDs status is "Critical".

Yet, people continue to hammer away on those SSDs, for not double the number of bytes written when things supposedly turned "Critical", but 100x the number of bytes written, and the SSD keeps reporting critical, yet keeps working at full speed with no performance issues.

So, yes, our host is correct that there is a finite number of writes that a SSD can handle. It will, in theory, eventually wear out. But it will probably outlast your computer, and nearly every part in your computer, before it wears out. It will likely live on long after you are 6 feet under.

Now if you have a $2 SSD or a freebie from a giveaway, those SSDs are slow beyond words. Perhaps, with their ultra-low-end quality, they will wear out if you use it 24/7/365 without rest? But that assumes that anyone can write enough data to them to wear them out, because writing data to those snails takes half of forever.

But for an SSD that is included in your computer purchase, you will never wear it out. If your SSD dies, it is due to a power hit, overheating, controller failure, or some manufacturer's defect. If your SSD dies, it will not be because you over-used it.
