Hi anita54 ,
Welcome to the Community Forums.
Tech support would be the guys that can decode WHD01000-DL7086 for you .
It maybe a a simple drive block error or bad data sector but if you are experiencing slow performance or freezing , try re-running individual storage test and cross check it with other diagnostic test similar to this and this .
Note the result of SMART read and write if it would show any error and call in tech support for intervention.
Back up any important data to a different storage to be on the safe side.
Update us how things go.

The message means that your system's hardrive is beginning to go south, so if it is still under warranty, backup your data ASAP, because the new drive will probably just have the generic Lenovo load of what ever OS and software that your system originally came with.
Note: If the drive is going south, the more you use it the shorter its life span, so do not do a bunch of testing on the drive before you first back all of your important data.
If it is out of warranty, a good computer shop may be able to still clone your old drive over to a new drive for you depending on the state of the old HD, and you might even consider going to an SSD, or getting a bigger and faster HD than it originally came with, or both if your system supports it.
