Hi guys,

My first post so here it goes:

I've added a Ubuntu 64-bit guest to my Windows 7 machine.

I connect a USB device to the VM but when I try to copy files into it I always get this error saying: "error splicing file: read only file system"

I can't seem to find a solution to this problem.

Also when it gives me this error the USB drive automatically disappears from the VM and I have to restart to have it mounted again.

I hope I can find a solution for this!

EDIT: I've tried to copy small files and it's working fine but when I copy a big one the USB drive ejects automatically and then this error comes up.

Post the guests log file ( as an attachment ). Right click on the guest in the Main Manager then click show log. Save and post as an attachment. Compress if it is too large to post.

Here's the log

Set the guests CPU count to 4 and see if that helps.

Nope, it stopped again in the middle of the copy process

OK so leave it a 4 CPU and change the USB to eHCI instead of xHCI and see if that works.

How large is the file anyway?

I need this VM to do just this: copy files into a ext3 drive. Normally I get huge files beginning in 130GB till around 200GB.

If I use eHCi I only get usb2.0 speeds right?

EDIT: If I use eHCI I get the error message when I connect to the drive saying:
Failed to create proxy device for the USB device. (Error: VERR_PDM_NO_USB_PORTS).

Yes that's correct, but it is for a diagnostic test so it must be tried.

Just to be clear this is to see where the real issue is. The log file does not show any issues and assuming that log came from one that failed then it puts the problem in the host, guest, or the host side VBox code.

Here is a search link that describes this error in detail. https://www.google.com/search?q=error+s ... ile+system

So what I did was change from 14.04 to version 13 and copied the same file and it worked.

I am going to try some more tests but this seemed to do the job. I'll post the results!

Thank you for your help!

OK, tried with another file on another disk and the same thing happened, now the error says:

Error splicing file: input/output error

It's the same as in the link you gave me. I'll look for one of the solutions posted there.

I tried everything from changing the Disk enclosure to changing the usb ports in the computer, to copying a zip file, making a folder inside the disk and copying into the folder, nothing helped until now

Have you looked at the syslog and dmesg to see what is reported?

You lost me there, sorry how do I do that?

I was searching and searching and searching and I also have another guess that it might have to do with the usb drivers on windows 7 supporting or not the xHCI.

Now the thing is, which should be the best drivers?

The thing is I tried a lot of times and some times works and like 90% of times doesn't. I just can't figure what makes it don't work.

I don't know what more to tell you. I transfer huge files all the time and have never seen this issue. From what I read though it points to hardware on the host or host OS itself. I would think that the translation mechanism from one formatted drive to another different format might have something to do with it. I only use ext4 or btrfs sometimes on everything. You can always post a ticket at bugtracker and see if the DEVs have any idea.
