Need to mention that bad sectors can’t be fixed since they are actual physical damage to the disk surface. How long does chkdsk f r take? If you run chkdsk /f /r command in Windows 10, it may take quite a long time since it will check every sector on the disk. Sometimes it may take a few hours depending on the partition size and your computer performance, so be patient. If you only run chkdsk /f command in CMD, it costs much less time. Does chkdsk erase data? No, generally CHKDSK doesn’t delete files. It only finds and fixes disk errors in Windows 10. However, if you find CHKDSK deleted some files after the disk checking, you can easily recover CHKDSK deleted files. Does chkdsk fix corrupt files? If you only run chkdsk command by itself, it will scan the drive in read-only mode and report detected errors, but not repair them. If you want CHKDSK to attempt to fix logical file system errors in the scan, you can add the /f swtich. To fix corrupt system files, you can run another command: sfc scannow. Which is better chkdsk r or f? Generally you can only run chkdsk /f. If you really need to check bad sectors on the disk, you can run chkdsk /r. How do I run chkdsk in Windows 10? You can open Command Prompt and type chkdsk /f or /r in CMD, hit Enter to run CHKDSK in Windows 10.

CHKDSK /F /R vs CHKDSK /R /F Windows 10

If you want to repair a corrupted hard drive and try to run both chkdsk /f and /r switches in Windows 10, you can type chkdsk /f /r or chkdsk /r /f command in CMD in Windows 10.

There no much difference between chkdsk /f /r and chkdsk /r /f. They do the same thing but just in different order. chkdsk /f /r command will fix found errors in disk and then locate bad sectors and recover readable information from bad sectors, while chkdsk /r /f conducts these tasks in the opposite order.

However, there is no need to run either of the two commands above. You can only run chkdsk /r command since it includes the /f function. However, if you only want to fix disk file system errors, you can only use chkdsk /f command since it will cost much less time.

Need to mention that you don’t need to run a chkdsk /r commasnd unless you think the target hard drive has physically bad sectors. This is because, checking 1TB hard drive may take more than 5 hours depending on your hard drive performance.

CHKDSK /F or /R – Differences

Based on the disk error types, you can use the corresponding CHKDSK commands and switches to fix disk errors. CHKDSK /f and CHKDSK /r are most commonly used two CHKDSK command switches. You can check their differences below.

chkdsk /f: this command can find and fix any errors on the hard disk.

chkdsk /r: this command can detect and locate the bad sectors on the target hard disk, and try to recover the readable information from the bad sectors.

Do you have to run both chkdsk /f and /r switches, namely, chkdsk /f /r command in Windows 10 to fix hard drive errors?

Generally chkdsk /r not only does the same thing as chkdsk /f, but also checks the bad sectors on the hard disk and tries to recover the readable information. Running chkdsk /r also means that the chkdsk /f is run. However, running chkdsk /f will only check for logical disk errors, but not bad sectors.

Therefore, if you only want to check and correct logical disk errors in the file system, you can only run chkdsk /f command; if you want to find physical disk errors in the disk, you can use chkdsk /r command.
