New 2TB WD2001FASS, Windows 7
Read performance seems fine, but writes are awful. Takes several hours to format a 50Gb partition.
HDTune file benchmark shows less than 10 Mb/sec for writes. Screen shot is here (blue are reads, orange are writes):
Also, WD’s spec ( http://www.wdc.com/wdproducts/library/SpecSheet/ENG/2879-701276.pdf) says 138 Mb/sec.
Windows driver configuration for the hd has checkmark next to “enable write caching for the device”.
I didn’t touch any jumpers.
Is there anything I can try (jumpers, firmware update) ? Any help is greatly appreciated!
