I also noticed that issue on a far more powerful machine and the WDC 2TB drive. At first I thought the drive was broken, then I switched from ext2 to ufs2 that improved efficiency to an acceptable level, but still it does not look as it should, maybe something wrong with the SATA(2) driver or the WDC drives :-) Glad to hear I am not alone, thanks!! :-) -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
