Just an update on this problem:
It does NOT appear to be the usb external drive anymore! I just plugged the latter into my laptop and all worked perfectly - No badblocks and large file copy worked perfectly.
Confirming that the problem is NOT a USB external hard drive problem.
I have no clue on where an "Error splicing file..." would come from. But I had something that matches some of your other symptoms - large file accesses failing under one distro, okay under another - but this was real file corruption, and an internal disk. Years ago I had an internal disk giving corrupted large files, which turned out to be a RAM problem which *only* showed up on large file accesses. Intermittent RAM fault seemed to have fallen on statically allocated kernel buffers which only got accessed on large file writes (and may be reads, can't remember). Douglas
I have successfully read/written large files several times onto the USB drive using 4 different distro installations with no error and no badblocks shown in any of those distros. I have used Ubuntu 13.10, Linux Mint Debian and a fresh install of Debian 7 (latest) on the same original host and also attached the USB disk to a laptop with UB 14.04). All worked fine.
Good news is the USB drive looks ok and I have not lost any data. Bad news is I got no idea where to look for the original problem and why it came up in the first place!
The actual error is "Error splicing file ..." and there are references to this error on the web, but no solution.
Of possible interest, if I connect the USB drive directly to a KVM guest VM with Debian 7 running on the original host, the drive works fine, (except for a serious slow down as one would expect.)
So any ideas where to look for a fix for original problem would be nice?. But its not critical anymore.
Cheers, Daniel.
