1) Always make sure your system is clean of viruses and use scandisk to
check the file system's integrity - no point making changes to a system
based on corrupt files, as things will likely stay corrupt. Try
scanning the registry too with your favourite registry scanner.
2) Use a program like Sysinternals (Winternals now under Microsoft)
ProcessExplorer. If a process really IS using the USB drive, then you
can do a search for exactly what is being used by searching for
"<DRIVE LETTER>:" and interpreting the results. Malware could be
using it or just a program you were running hasn't correctly
'signed-off'. You can force-close the offending item if nothing else
works. Then the drive should allow itself to be safely removed.
3) Check your USB chipset drivers. Install any updates available, or if none are, then uninstall & reboot, then re-test.
4) Power is the baseline for everything electronic, people forget this
too often. If you can, check the PSU (an external one I assume with
this model of drive) with a multimeter.
5) Try on another PC (preferably with the same OS) at length.
6) Try with a different USB cable.
7) Try with the Firewire cable as a workaround (the hardware/chipset
used is different, so likely to encounter different hardware/software
issues, but interesting to check if any similarities).
GOOD LUCK - I hate USB, it's so fiddly with all the different
driver/chipset/hardware implementations that it can be a nightmare to
troubleshoot.
