Hello all. I've been getting glitches in my recordings and I suspect the hard drive might be faulty. The Humax HDD test shows no errors. I tried running the fix-disk command via telnet but I get the message: humax# fix-disk Checking disk sda Unmounted /dev/sda1 umount: can't umount /mnt/hd2: Device or resource busy Any suggestions? I'm running Custom firmware version: 2.12 Humax Version: 1.02.29. Is there another way to check the hard drive without removing it from the case? Thanks in advance.
