When your external hard disk is inaccessible, unreadable, corrupted, or crashed, or it shows up as a RAW in Disk Management, you can run CHKDSK /F or /R to repair it. How to run CHKDSK /F or /R to repair external hard drives? If a file system with a light logical error, though there are some tiny changes during the repairing process, your files are still kept there. Thus, data loss happens.Д¬ommonly, the data that you can notice is lost is usually caused by heavy file system issues. And then reorganize the logical structure of the file system (or we say the disk's file allocation table) through new computing algorithms to make the disk re-accessible. That's because when CHKDSK /F or /R repairs logical errors, it needs to delete corrupted or invalid indexes first. It may be the question of greatest concern for most of us.В CHKDSK won't make data loss when scanning a volume, but it possibly will when repairing disk errors with parameter /F or /R. Notably, running CHKDSK /R /F or CHKDSK /F /R has the same effect as running CHKDSK /R as CHKDSK /R contains the role of CHKDSK /F while running /F and /R waste at the same time only waste more time. For CHKDSK /F /R, it runs in the opposite order. The only difference is the checking order.Д¬HKDSK /R /F checks and fixes hard drive errors first and then locates the found bad sectors and restores readable data from the bad sectors.

CHKDSK /R /F vs CHKDSK /F /R on Windows 10Д¬HKDSK /R /F and CHKDSK /F /R do the same check and fix work for the target hard disk. It will fix the possible errors on the disk and simultaneously check if the disk has bad sectors and do readable data recovery. If your disk is unmounted, unreadable, inaccessible, or corrupted, you can run CHKDSK /R. If you just proceed routine check of your disk, running CHKDSK /F is enough. Thus, using which one of them depends on your situation. Usually, the CHKDSK process will take hours for a 1TB disk. That's because CHKDSK /R not only checks and fixes logical disk errors but also diagnoses physical disk errors. Running CHKDSK /R will cost more time than running CHKDSK /F. It seems that CHDSK /R is better, right? Not absolute. As mentioned above, CHKDSK /R includes the functionality of CHKDSK /F and also has additional analysis of physical disk errors. Most of you may be confused with the same question ' Should I run CHKDSK /R or /F?'. What needs to mention is that both of them can't repair the corrupted files like videos and photos on the target disk. Besides, locate bad sectors on the disk and try to recover readable data from affected disk sectors. Here are the differences between CHKDSK /F and CHKDSK /R:Д¬HKDSK /F: Check and fix the file system errors on the disk.Д¬HKDSK /R: Check and fix disk errors. Both of the two CHKDSK commands are used to fix the logical errors of a disk. And /F and /R parameters are the most commonly used. CHKDSK /RД¬HKDSK has kinds of parameters, which help users solve different disk errors. But usually, users use First Aid in Disk Utility to repair disks. But it cannot repair the physical disk errors. When used with parameters like /F or /R, CHKDSK utility can also repair logical disk errors and restore the file system integrity of the volume. What to do when CHKDSK fails to run?Д¬HKDSK, a cmd command, is used to check the logical and physical errors of the file system (In computing, a file system is a way for storing and organizing files) and file system metadata of a volume on Windows. How to run CHKDSK /F or /R to repair the internal hard drive? What does CHKDSK /R /F or CHKDSK /F /R mean? Differences between CHKDSK /F and CHKDSK /R? More importantly, if CHKDSK /F or /R gets stuck or fails to check a hard drive successfully, here are testified solutions to help you out. It also offers the detailed steps of how to run CHKDSK /F or /R to check and repair hard disk errors on Windows 10/8/7.
