Western Digital JS series drive temps are wrong admit WD
After having very high temps (via Speedfan) on my WD JS160 sata drive; around 55-60°C, while the Maxtor right next to it was always around 30-35°C, I asked WD what the problem was. Here's their reply;
Dear Mr Anderson,
some new JS version have a fault in the temp algoritm coding, that's why the temp can be 20C over the actuall temp. We are still working on a sollution for this( maybe firmware update, but it is not sure).
You data is safe only the reading of temp is wrong. We are still working on a sollution. You can offcourse make an RMA replacement, but we advise to do this in about 1 month, because the js and KS models are given a new firmware and are now not in stock.
Again, your data is safe, the temp reading is not correctly given, for other sugestions, we will always consider it.

Now I'm a little bit more at ease knowing my drive isn't going to burn out.
Just thought I'd post this so other WD users can benefit from their reply.

All you really need to do is calibrate the offset. Check the temp immediately upon booting into windows from a cool overnight start. The HDD doesn't change temps all that fast, so compare the HDD reading right at the start to the room ambient. That's your offset.NoizEnvader wrote:Same here. I've got the WD1600JS and temp reading is currently at 59C, yet the drive is reasonably cool to the touch.
My most recent Samsung SP 80GB, an SP0842N, has a 7C positive offset - it consistently reads high. No problem, I just mentally subtract the 7C. Somebody told me that offset can be programmed into SpeedFan, but that's too much work. I like raw data.
