I have a wd my book home edition 500gb external drive connected to my hp pavilion dv7-1245dx laptop via a eSata cable. After some time my drive "disappears" from my computer. It also cannot by seen under device manager although it is still physically connected and powered up of course. If I click scan for hardware it will eventually find it. Sometimes also after drive spin down and I try to access a file on the drive, it spins up but screen just freezes until I shut down drive. I have already reinstalled OS, reinstalled drivers
, and even got a new drive. Can someone please help me with this. It does work fine with USB cable.
