Check disk errors

[darkness_awakens]

Hello,

I hope I am posting in the correct section.
I don’t know much about informatics, only the basics and following tutorials. My computer is running slower and my brother told me to perform a diskcheck and defrag.

I did a CheckDisk today and it shows the following errors:
The volume bitmap is incorrect
Windows found problems with the file system

Should I still do the fixing part? Or can it mess up my computer?
I plan on doing the diskdefrag after.

I have windows 7 Home premium. Service Pack 1
Only one HDD and no partitions.

Thank you for reading.

Lets run check disk and have it check and repair errors.

https://pchelpforum.net/r/run-chkdsk-using-command-prompt.20/

Here is one way that you can pull the log to view it.

Press the Windows + R keys to open the Run dialog
Type powershell.exe
Then press Enter.

In PowerShell, copy and paste the command below, and press Enter.
get-winevent -FilterHashTable @{logname=“Application”; id=“1001”}| ?{$_.providername –match “wininit”} | fl timecreated, message | out-file Desktop\CHKDSKResults.txt

The CHKDSKResults.txt file will be created on your desktop,

COPY and PASTE the contents from the CHKDSKResults.txt file into a post.

The volume bitmap is incorrect

Look like it fixed it

CHKDSK discovered free space marked as allocated in the
master file table (MFT) bitmap.

Go head and run the windows defrag.

The bigger question is how big is the HDD and how much free space is there?

Good to know that it’s fixed,

The disk has is 1Tb and has 140Gb free.
