Copy files from Ubuntu 12.04 guest to host corrupts file content

[ppxnouse]

Guest: Ubuntu 12.04.
Host: 10.11.6
Paralles version: 12.0.2
Every file I copy from the Ubuntu guest to a shared folder on the host gets corrupted. Looks like it takes wrong parts of the VMs disc.
e.g. if I copy a large file - I can find the content to several unrelated documents within the copy of that file on the host.

It would be great to get some additional bits from you:
0. what method do you use for copying (using shell commands or via Nautilius or something else)?
1. what the the typical size of files being corrupted?
2. what's the kind of those corrupted files (text of source code or OpenOffice documents or something else)?
3. is *every* file being corrupted or just some part of?
4. please, generate Problem Report on the running VM and post its number here.

0. does not matter. cp in shell or d&d in nautilus. Both give the same result.
1. random - since it is virtually every file. If it is a very small file (20 line text file) - you might be lucky. All the rest is not the same when it lands in the shared folder.
3. All. logs, sourcecode, binaries. Like written in OP - looks like they contain random parts of other data from the VMs disks. Sometimes zeros. Looks like it is getting the wrong offset -blocks etc. from the virtual hdd file when moving the data.
4. 118765590 - please note that I renamed some disks images after abandoning the VM.

This issue could be fixed by generating a new VM and attaching the old VMs disks to it. Anyhow it would be interesting to see a solution since this is not the first time I see this on a Ubuntu Parallels VM.
Thanks.
