Chkdsk "found" folder missing

Hi,

I moved files to my external hard drive at work and I can't see them on my home PC. I ran a chkdsk in Command Prompt and it shows the following:

39 unindexed files recovered to lost and found.Lost and found is located at \found.005

The problem is that I can't find the found.005 folder. found.000 to found.004 are there but not found.005. I have the "show hidden files" option enabled.

This is not the first time that this happened with this hard drive and usually after I repair the disk I can copy stuff at work and I can access it at home but I lose the files. I'm running Windows 10 64 bit on both machines. Any idea what is causing the issue? I am using ESET Nod at work and Windows Defender at home so I'm not really convinced that it is a virus.

Thanks.

I usually wait for the PC to switch off before I remove the drive. This is hours after I the copy operations are finished so it's weird. The data is written to disk because I can see the files with recovery software but it doesn't help me much because the original folder locations are lost.
