To do a defrag I think SilverAce will need to mount the drive on a Windows system. IMO defrag on NTFS has always been overrated as a solution to any problem, its a hang over from FAT and something with which to kick the can down the road - maybe Draghi should defrag the Euro

The 'drivers' from Paragon etc should be properly called called emulators. I use file system emulators on a Solaris system for NTFS and HFS+; performance of both is poor compared to native NFS over USB.

@SilverAce - if you've not done so already, I suggest you replicate the library to an HFS+ volume and point Calibre at it, if performance is OK then the problem is almost certainly the use of NTFS, although it could also be a bad drive, there may be OS/X utils available from WD to 'measure' drive health.

If you have access to a 'friendly' windows box, you could put Calibre Portable on it, and point it at the library on your WD USB drive - if its performance is acceptable then its 99.9 % sure its the NTFS on a Mac issue, if its slow then you may have a bad drive - WD have Windows utils for measuring drive health.

On reflection the data is being written to the NTFS volume via one of these so-called 'drivers', so a defrag may have a bigger effect than I would normally expect. Who knows how they manage the drive space.
