Windows 10: Windows 10 must have corrupted files on my CF card

I have a CNC milling machine, C-tek. Today, I wanted to make a copy (clone) of its CF card. I took the card and read it on my PC (windows 10) through a card reader. Clone it, Then, return in it back to the CNC machine. After that, I started the machine, MS-DOS started, few message were shown, and then the machine freezes with black screen. I think that windows 10 modified some files on my CF card. Is it possible? I know windows defender can do something like that, but I had a look at the notifications and found nothing. The card has many EXE and bat files and others. I wish I could return my CF card as it was before it was read by my windows 10. What is your recommendations? My windows version number is 10.0.17134.

Windows 10 corrupts files without warning on SD & CF memory cards (FAT32)

What sampler? (Brand, model, serial, OS version)

Do all files from the sampler corrupt in 10, even on different CF cards? Do they not corrupt in Windows 8? I want to make sure it's not just a bad CF card.

The problem found over the summer was a very specific one due to a partner not writing a file correctly on FAT32 cards. So we added additional checks to work around the problem in their code.

Windows 10 corrupts files without warning on SD & CF memory cards (FAT32)

Summary: Windows 10 suspected to corrupt/destroy files without warning on memory cards when plugged in

Problem description:

• After upgrading to Windows 10 I put a SD-card (FAT32 formatted) into my external USB card reader.
• The files on the memory card appear in green text - internet search indicate the files are (or are believed to be) encrypted by Windows EFS:

• Going to properties | advanced for the file the attribute shows that "Encrypt contents to secure data" is ticked - clicking the Details button shows and empty window where "Users who can access this file" is empty and "Recovery certificates for this file
  as defined by recovery policy" is empty:

• Trying to untick "Encrypt contents to secure data" followed by OK and Apply results in "Access Denied" and then "Error Applying Attributes" (I have administrator privileges on my account and I use Run As Administrator on my Windows Explorer)

Further steps performed:

• On my Windows 8.1 laptop, using the same card reader and card, the files appear in black and not encrypted - but they appear to be corrupt and can't be read as WAV-files following the "incident" on the desktop computer.
• I have two cards with the same files, a SD-memory card and a CF-memory card because my audio recorder records to two cards for safety and backup reasons. Unfortunately I tried to access both cards in the reader on my Windows 10 computer and both memory
  cards now behave the same - messages as above on my Windows 10 computer and corrupt when accessing them on my laptop.

Since this happened following the Windows 10 upgrade, and the same behaviour took place on two memory cards, and EFS is not supported on FAT, I can only guess that this is a very dangerous bug.

I contacted Microsoft Support using the Contact Support app chat who referred me to post the issue this forum and also said that the issue is under investigation.

Does anyone have more information on this issue? And can the files be saved somehow?

 

Corrupted file RAR

If the archive has been created using WinRAR, why don't you try WinRAR itself? It has a built-in repair feature for repairing corrupted archive (ZIP as well as RAR). Follow the steps given below:

• Open WinRAR application in your system.
• Now click on File tab > Open or simply press Ctrl+O.
• A small window "Find Archive" will pop up. Locate the corrupt RAR archive from your system directory and select it.
• Now click Open button.
• Click Tools tab > Repair archive or simply press Alt+R.
• Again a small window "Repairing File name.rar" will pop up.
• Now click Browse to select a location to save the repaired archive.
• Check the box "Treat the corrupt archive as RAR" and click OK.
• WinRAR will start repairing of corrupt RAR archive. Once it gets completed click Close.

I hope the above steps will help you repair the corrupted RAR archive.

Thanks.
