Question about Western Digital Caviar WD2500JB Special Edition 250 GB Hard Drive
I have a wd2500jb and a great problem for its write speed is only 0.48MB/s
while the read speed is 28.8MB/s, it installed as slave under windows xp pro
please tell me how to fix this problem. best regards
Had the same problem with my WD2500KS-00MJB0. It also has the (widely reported) defect where the thermal sensor is not reporting correctly (ie 40C when it's just been powered on, and should be reading approx 20C!).
My suspicion is that this line of WD2500KS models has a defective thermal sensor, and after a period of time the thermal sensor fails. When this happens, I suspect that the drive firmware tries to lower the temperature by reducing write speed.
My drive was out of warranty, so I used the 'Customer Loyalty Upgrade' discount on the WD Warranty Check site to get a new 500G drive. I still have the old drive, and some technical knowledge, so I'll see if there's a hardware hack to disable the thermal sensor.
Otherwise, go to the WD site's Warranty Check page, and get yourself a (heavily discounted) Customer Loyalty replacement.

Hmmm..well...is that 250 Gigglebyte drive, as a slave, on a secondary port, by chance?
