Unable to copy to the external hard drive
Solvedgugu01 Posted messages 15669 Registration date Status Contributor Last intervention -
Hello,
It has suddenly become impossible for me to copy to the external hard drive, while it works perfectly in the other direction. The brand's diagnostic software (WD) confirms that the drive is working fine.
What can be done?

Hello,
Start by backing up your data to another drive < Important
Then launch Windows PowerShell (Admin)
Type chkdsk /f x:
(Replace x with the drive letter)-
Excellent! chkdsk has resolved everything, thank you!
"Added 23 defective clusters to the bad cluster file.
Fixed errors in the BITMAP attribute of the master file table (MFT).
Fixed errors in the volume map.Windows has made corrections to the file system.
No further action is required."use CrystalDiskInfo as indicated to check the health status of your drive
https://www.commentcamarche.net/telecharger/utilitaires/6735-crystaldiskinfo/ (yes, I forgot the link in my previous message)
bad sectors, your drive must be in poor condition.
If caution in health means it is likely defective, move your data elsewhere and buy a new drive.

Good evening,
(in addition)
Is it correct to say files on the PC to copy to an external drive? (messages 1 and 3 contradict each other on this point)
> What is the size of the file to be copied?
> Right-click on your external drive, choose properties and indicate what file system it is (fat or ntfs...)
> Use CrystalDiskInfo, download it and run it, it will give you the health status of your drives.
You will have a tab for each drive
Provide the health status of the PC drive and the external one.
> And what is the free space on your drive?

Without regular feedback from you...you can always refer to article 22 ;-)
A little reminder regarding the volunteers who are helping you: Reply, Respect, Politeness,...-
Indeed, CrystalDiskInfo indicates a "caution" message. I'm not quite sure how to interpret everything else below. The data is moderately sensitive, but it seems to suggest that an unrecoverable crash is likely to happen soon, right?

Good evening,
If it's working very well, there’s no problem..!! I have to say that apart from that, you're not very talkative when it comes to explaining things, at least a little bit.
jeannets Posted messages 28398 Registration date Status Contributor Last intervention Ambassadeur 6 603
Provide useful information... The brand and model of the PC, its age, its operating system and version...
Information about the disk, the WD model..? Have you used it on a TV to record movies..? or a MAC
It might be a write protection..?? with this PC..?
Does this disk work on other PCs..?
The file might be too large..? corrupted..?? defective disk sector..? Insufficient USB power..? etc..etc..? the name of the file with disallowed characters..?
Reading on the subject https://recoverit.wondershare.fr/harddrive-errors/fixed-cant-read-from-the-source-file-or-disk.html
Sorry for the confusion: in the disk -> PC direction, I get the message "Action interrupted. Unable to read from the source file or disk." This is surprising because the same file can be transferred to a USB stick without any difficulty.
