    Ridiculously slow file transfer

    Hello
    For the past week+ I have been experiencing very slow file transfers, moving files from one HDD to another - both internal, connected with SATA, should anyone care..
    When I move any file, regardless of its size, it is moved with 1.1 MB/sec at very best
    That's a major pain in the behind, even for moving small amounts of data!

    If anyone could point me in the right direction, or give me a solution, it would be greatly appreciated
    Do tell what information you need

    It would appear the problem isn't there, when moving files to a USB flash drive - Formatted NTFS..

    Check that your SATA cables are fully inserted, they may have got loose.

    well with them both being ext4 I'm not sure what the problem might be. I've done some research and there was a problem copying large files. causing slowdowns of the entire OS but i cant see anything directly related to your issue. sorry i cant be of more help.

    Just checked and double checked that, and they didn't seem loose, nor did it fix the problem - But thanks nonetheless

    If nothing else it at least tells me, that it's not just my system using all its resources on file transfers - At least used to..

    Do a file transfer. While waiting:

    Open a terminal:

    dmesg | tail -50

    Any disk-related messages?

    I had similar thing happen to me on Dapper Drake machine that had been up for several years--continuously. I was getting read errors and IO waits in the dmesg. Great, failing hard disk.

    Opened up the machine. The power connector to the drive had vibrated loose (after several years) and the drive was literally going to sleep without power. The kernel said, "I'll just wait here until the data comes back."

    As far as I can tell, it doesn't say anything like IO-error or the like..But then again, I'm not sure what to look for
    It does however mention something about some error and remount..?
    And by the way, the two discs are sda1 and sdb1..

    Here's the output of 'dmesg | tail -50'
