So I had a few large files to copy, about 5GB each. From/to same partition. Start the copy, it says '3 minutes left', so I think....a quick solitare game. And poof...system hangs. Nada. Nothing. I wait about 5 minutes, and nada...mouse is obviously not working. Power down, reboot. And of course the new directory I was copying to doesn't even exist after a reboot.
I have two physical hard disks, one around 200GB and one 1TB. I had the large one splitted into 3 partitions around 300GB each. I used Windows XP.
Yesterday I formatted the small disk and installed Ubuntu 10.4 (trying not to mess with anything in the large disk).
Now from within Ubuntu I can see only the third partition of the large disk (referring as size 1TB).
When copying large (or even files of a few KB) to an sd card from ubuntu 10.10, the files appear to be there but when i access the card from another device, the files are either missing or 0 bytes in size.
I suspect that the problem is that it takes time for the files to copy to the card and I'm taking it out too soon but there is no progress bar - im just doing it from cmd line.
I have very large data disks on my computer. To prevent data loss from crashes or 'hostile action' I keep a backup copy. I prefer to have the back up as a 'mirrored' disk and not as a compressed 'backup'.
Today while copying a large file from my computer to the external hard disk, it got interrupted and copying stopped. Afterwards when I tried copying again, the process of copying started from the beginning. Why it did not copied the only portion that was left behind.
I have CentOS 6.4 64-bit PC with 24 GB of memory. I typically use /dev/shm extensively for large temporary files. However, about a month ago, it started behaving wierd. When I copy large files to /dev/shm, the PC slows down and starts swapping to disk.
