Windows 10: Can't Stop Sharing Folder - Doesn't Exist

Windows 10 Pro Version 1909 (OS Build 18363.720)

Quite some time ago, I shared the DVD drive of one machine with my Surface Pro 4. Unfortunately, I was dumb enough to map it as D: drive. Now, every time I insert a USB stick into the Surface, it thinks it's that shared DVD drive. It's mapped location is:

\\Acer-Office\Acer_DVD

I am trying to disconnect that old share (no longer map it) on the Surface, but I get an error that it doesn't exist. I have used an elevated command prompt and ran the following:

net share sharename /delete
Result is "share doesn't exist" (something similar)

I've tried two variations of the sharename just in case it was a syntax error: \\Acer-Office\Acer_DVD, and I've tried simply the Acer_DVD. Same results.

I went into Regedit and located: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Shares. where there is no reference to the DVD drive.

I mapped the same DVD drive to another drive letter successfully (setting it to S: drive), and am able to disconnect it, but the old drive letter (D persists.

Can anyone provide some guidance on how to get rid of that mapped network D: drive?

Windows doesn`t start. Authomatic repair doesn`t work.

Thanks again!!

I`m sorry I had not noticed that the text on the picture was in spanish. It says that windows has replaced some damaged clusters in "name" file and "directory". Then, at the end "an unspecified error occurred (75736e6a726e6c2e 4f6)".

I`ll do it and I`ll be updating this thread when I have the report.

I ran SeaTools. These are the results:




Does it mean my HDD is useless?

Thanks for your answer, ken!

I deleted all my data. I had have it backed up.

I did a clean installation using the windows media creation tool (usb option).

No, I didn`t. I thought a clean installation would solve the problem.

After posting my previous message, I did it.





After chkdsk, I close cmd and tried to boot and the laptop just turned it off. This morning I`ve restarted it and automatically windows did a repair. Windows has booted and it seems that the repair tool has removed chrome and acrobat pdf reader (the only two programs I had installed after reinstalling windows).

Now Windows is installing updates and restarting my lapop, I`m kind of frightened. I don`t want it to happen again. Anyhow, I want to know what has brought the issue

I`ve been looking for information about the error code at the end of the picture and I didn`t get anywhere.
