Western Digital Corp. (WDC) - Get Report shares were up 0.64% to $85.51 premarket after the company received assurances from Toshiba Corp. (TOSYY) that the company would provide it with notice before selling the chip unit which both companies have a stake in. 

Toshiba is looking to sell the memory-chip unit, including its joint-venture interests, as it attempts to recover from the collapse of its U.S. nuclear unit, which threatens to bring down the entire company. 

"Our goal has always been to protect and preserve the health and future of our successful joint ventures. Our ongoing discussions with Toshiba and its stakeholders have been constructive, and we will continue to work to seek a solution that is in the best interests of all parties," Western Digital said in a statement.
