I have Ubuntu 16.04 running on a Windows 10 host in VirtualBox. I'm trying to
rsync a large folder (192GB) onto an external USB hard drive enclosure (Orico USB 3.0 2.5 SATA III) containing a Samsung 830 SSD (240GB). The disk is formatted as NTFS, and I have
ntfs-3g installed on Ubuntu.
The operation starts out fine, but at some point the
rsync fails and the USB seems to have unmounted:
rsync: rename "/mnt/usb/bitcoin/blocks/.blk00201.dat.vptzQx" -> "blocks/blk00201.dat": Input/output error (5) rsync: mkstemp "/mnt/usb/bitcoin/blocks/.blk00202.dat.QAivPb" failed: Input/output error (5) rsync: mkstemp "/mnt/usb/bitcoin/blocks/.blk00203.dat.XoflbV" failed: Input/output error (5) ...
I can see in VirtualBox that the USB drive has been unmounted:
I'm not sure which logs I can check to see why it's unmounting. Suggestions?
