Ah -- good catch. According to the man page, you can pass an "mft zone multiplier" to mkfs.ntfs (option -z), with values 1..4 corresponding to 12.5%..50%, default being 1 (12.5%). Perhaps the OP has more luck with bigger values? > Howsever, I suppose, others know better than me, like before, just an idea... No, no -- I think you were spot-on! Cheers -- t
