Data error cyclic redundancy check on an external hard drive is common while trying to access a drive on a PC. But what is a Cyclic Redundancy Check? Cyclic Redundancy Check (CRC) is a simple data verification method that your Windows system uses to check the accuracy of data on different storage devices such as hard drives, CDs, DVDs, and USB Drives.

In general, the Cyclic Redundancy Check error occurs when CRC fails to verify the data due to accidental changes to the RAW data on the hard drive. Although, several other factors can also trigger this error including registry corruption, a cluttered hard disk, an unsuccessful program installation, misconfigured files, etc.

If you encounter a “Cyclic Redundancy Check” error, the specific drive will become inaccessible and you won’t be able to load its data at all. Here are 3 workable methods in the video that you can try to fix the data error cyclic redundancy check.

Started with the third method and it worked for me. Took less than 5mins for a 500gb external hard drive. Thank you so much

[foedeer]

Thank you so much, I ran the chkdsk on a 2TB external hardware, took about 7 hours, but solved the CRC error

[Americka]

First option worked! Thank you so much! This took me about a day just waiting for it to check my hard drive. Just a heads up on that.

[zackio]

The third method took only 10 minutes and worked very well, so I'd recommend starting with that one.

[gamebugz-blockstrike]

I just want to understand: these methods would be applied only on hard drives, like if I have a disc/dvd and during the setup it reads the CRC error, should i use one of these methods or just clean the disc

[HoangAnhNguyen-jsdo]

All 3 methods are failed to recover my data. Cyclic redundancy check, raw drive, bad sector are still there. The cost of fixing my external driver is 4 times that of the driver itself.

Please continue making excellent videos like this one. It was very clear, well laid out, good close up screen and easy to follow.

Thank you.

Useless if windows doesn't assign your hard drive a drive letter.

"the bad sectors will only be repaired if the "/r" option is specified."

[onaihpaul]

Started with no 1 - it started reading then when it got to 160, it started showing unable to read files A1, then went to next line unable to read file A2 & so on.

I moved to step 3, went on tools scanning and repairing is just there not moving or doing anything. It's an external drive, I just moved stuffs from my system to a particular folder refused to open.

how can i run method 3 ?i cant see my external hard drive, only in device manager (and all this problems start after an windows 10 update

[scariasebastin]

For me external disk itself not reading. From disk management am getting CRC error. So does `recoverit` software can help to fix?

[florriacarrell]

Thank you recoverit for the videos I got my external back by using your methods

[tmoha]

I did 1st way fixing and it says windows is replacing bad clusters on file papers.txt and it working on over a1000 file now, what do u think?

[trustee]

Please I need someone to help me resolve the issue below. I have two hdd drives (not my main OS drives) 1TB and 500gb I want to use the 500gb as external backup and the 1TB as internal, but when I connect the 500gb to my external case, it doesn’t work ( shows as allocated and not even recognized when I use diskpart. Also shows as not initialized under disk management ) and when I try to initialize it, it shows cyclic redundancy check. But when I connect directly as internal disk, everything works 100%. I thought the external case was the problem then I decided to put the 1TB on the external case and it works 100% well ( both as internal and external) and I don’t want it to be as external. Please can someone help me identify the issue here ?

[vishnuvaravath]

I am getting Error for a particular folder. What do I do for that?

[jacklesnar]

think you should have started with no.3 lol, , worked for me after 1 and 2 failed, , thanks alot mahn this was super helpful
and yeah i just hit like and that subscribe button

[warunakumara]

sir how do we try them if the external hdd is not showing in my computer or this pc ( windows 8.1 )

[TheFifaFootballChannel]

how do you run checkdisk when the disc in question has no drive letter because its not initialised?

[lionablaze]

Method 1 fixed my issues. Thanks for saving me a lot of headache dude.
