Hello, forum!

Connected my external WD HDD 4TB and three flash drives 32 & 16 & 4 MB to my HP laptop with Roswill 2.0 USB 7-ports hub.

Laptop didn't recognized them, no matter what I did - reboot, checked BIOS, check device manager. They were working perfectly fine just before I connected them to laptop through hub. I added a hub for convenience of switching, b/c laptop have only 2 usb ports.

I disconnected a hub and tried to connect HDD and flash drives directly to laptop, but now they're not recognized by laptop at all!

I tried again everything again: reboot, BIOS, device manager, uninstall USB drivers etc. Nothing!

I have very important and personal data on HDD and flash drives, and can't even think about lost of it. Is it possible that Roswill Hub fried something in my drives?

How I can save my information? What can be done? Please help, I’m really upset now.

P.S. Sorry for mistakes, English is my second language.

WD's external 3TB and 4TB enclosures are configured with 4KB sector sizes. If you purchase an enclosure with the traditional 512-byte sector size, then your data will be inaccessible.

I presume you have tried at least some of your devices in a different machine.

Is the hub a powered type? Can you measure the voltages at each of the 4 pins of the USB ports on the hub?

Is your WD drive an Essentials or an Elements model? Essentials are encrypted whereas Elements are not. It may be that the USB-SATA bridge board inside the enclosure restricted the damage to itself, in which case your HDD would still be intact. You would need to open your enclosure, but this will void your warranty. Ask WD Tech Support if they will give you permission to do this.

be sure to create backups of this stuff once you get access to it again. Never trust your important files to just one device. Everything breaks and you have to plan for it.
