I have an e-sata ext hd 1TB of verbatim. Since the last weeks, I have a very annoying problem. At random points in time it is unmounted and then re-mounted again. Sometimes, this is after 30 min, but more and more this time span decreases towards a couple of minutes. Of course, this is very annoying since in this way it is impossible to read or coppy large files to it. I have it only for less than a year, so it couldn't be because of heavy usage. I also tried it on a different (linux)pc and had the same problems with it so i guess it isn't because of the drivers.
The screenshot is fine, you can try the error scan also, it will scan all sectors on the HDD. Probably your HDD is fine though, and this is some other problem related to communication via USB.
I'm assuming you connect the USB cable directly to your motherboard's back USB ports without sharing a USB port with another USB device, right? USB shares 1 channel with 2 ports (so each 2 ports are like 'tied' to eachother).
Ah ok, then I was wrong in the previous post. My mouse was connected to the usb port next to the port of my hd (I'm assumming that on the picture, the two blue usbports are on the same channel, same for the two black ones?). Maybe that could be the problem. I will look to it how it behaves now.
I don't think that my mouse is usb2.0, just a simple and cheap logitech.
But one question suddenly popped up in my mind. I also have the same problem when I connect my hd to my laptop. Since there is no other usb-device connected, it could not share the same usb-channel.
Anyway, I will see how it reacts now. For the moment, my hd is being scanned for one hour now and did not have any disconnection problems (will not say this too loud,, otherwise it could have problems now )
In the case I still have problems, what would you recommend? Buy a new cable?
