Windows 10: lost drive

my Laptop updated itself last night and the D drive dissapeared

:)

 

Lost data from hard drive, what to do now?

Well, I'm sorry to hear that it's a WD My Passport that failed on you, @tomhenry ! *Frown
I'd recommend you to try using a different USB cable with it and see if that will help your system to detect it without it disconnecting.
I'd also suggest you to go to Disk Management and see how the drive is listed there. It won't hurt to check up on the health and SMART status of the HDD by running the QUICK and EXTENDED tests from the WD's Data LifeGuard Diagnostics. Here's a link to the available software: http://products.wdc.com/support/kb.ashx?id=11ZOpD

Give these troubleshooting steps a try and keep us posted with the results!

Lost the Seagate...

The drive seems to be completely dead, my computer will not boot if I have it connected...to the windows cd or the new installation on the F1 drive (which is the boot drive now by the way)

Thanks for the above article, im booting into Vista: U 64 right now, I cant follow those steps if the drive is in, it will lock up before it gets that far or if its not a cold boot the drive does not appear on the list.
