I need some help. I’m looking for replacement of power adapter for WD My Book Essential, but in Web I found 2 different informations about size of connector: 5.5 x 2.5 mm and 5.5 x 2.1 mm. Can anyone tell me something about that?
In this topic ( http://community.wd.com/t5/External-Drives-for-PC/Power-adapter-for-mybook/m-p/517216#M14378) I found information that Ktec has connector 5.5 x 2.1 mm. But on this PDF from WD site ( http://wdc.custhelp.com/ci/fattach/get/100048/0/filename/Power+Supply+Matrix.pdf)) the information is that connector size is 5.5 x 2.5 mm and this size is for many other WD products. In addition I tried to connect the power adapter from my TP-Link TL-WR1043ND router and it didn’t fit (I found that connector size is probably 5.5 x 2.1 mm). Connector from power adapter of Seagate My Expansion fits WD My Book.
The connector for WD looks like this:
