Hard Disk Partition

[yoonghan]

I've just had a hard disk failure a couple of days ago. Changed it and installed everything from scratch again on only one disk without partition. After installing, my drive suddenly has several partition that I don't know if it is actually normal because I did not create it. So I was thinking if it would affect my PC. Please clarify thank you.The three other partition other than the main C drive just appears.

The Windows install will make the partitions on the hard drive when it is installed.  That appears to be normal, so not to worry.  Most partitions are not visible to the user unless you go looking for them

Just to be certain, however, what tools did you use to reinstall Windows?

I used an external USB drive that has a Windows 10 installer in it. When I opened one of those partitions, why is there nothing in the recovery drive but it is almost fully occupied?

[TheOldMan · Accepted solution]

Those partitions are what Windows uses for a specific purpose and not for the user to see what is in there (in other words files are hidden)

FYI: deleting or modifying these partitions will probably cause Windows to quit working.  For the normal user - there is nothing to worry about.  To find what Windows uses those for would require extensive investigation

Thanks a lot old man! That clears everything up
