Problem with SEMAPHORE - Windows 10

Question

Hi,

I have sometimes errors message regarding semaphore.

NOTICE : I'm french and using a french version of Windows 10. So, I'm not sure for the exact translation of error message...

I have a batch that each night make a copy of my folder "Documents" to an external HDD linked by an USB_3.0 wire.

My "Documents" folder weights about 73GO and 950 folders and 22000 files.

In cmd.exe console, I can see that a minimum of about 9999 files have been properly copied (I can't see more assuming that the maximum height of cmd.exe console is 9999 lines...)

I can ask properties on destination folder using explorer and checks that before error 61Go, 838 folders and 20587 files have been copied.

and I can see that, for the last file copied, an error message is present :

ORIGNAL MESSAGE : "Erreur lors de la création du fichier - Le délai de temporisation de sémaphore a expiré."

TRANSLATION : "Error when creating file - Semaphore timeout has expired."

This errors occurs for the batch of THIS night.

This errors occurs for the batch of LAST night.

Answer 2

I finally use Seagate SeaTools for Windows.

I used all tests available, including full long test (4h) : NO ERROR.

Hum... I understand : nothing...

Making another copy/paste test, it blocks at 32%...

Answer 3

A simple CHKDSK H: gives me no error.

I'm currently running a CHKDSK H: /R to analyse sector physically...

Answer 4

Making another test of copy/paste of "Documents" folder, I obtain exactly then same result:

• at 14%, speed falls to 0 bytes/sec...

Answer 5

I just make a test :

I make a copy/paste of "Documents" folder from my internal SSD to the external HDD.

All works fine until 89% and then the speed falls to 0 bytes/sec and stop.

I let explorer to 0 bytes/sec for ten minutes...

And kill manually the process.
