On October 6, Western Digital fell 3.15% in regular trading, easing after the prior session's sharp rebound. The pullback comes as storage peers traded mixed, with SK Hynix down over 2% and Micron Technology down nearly 2% at the time, reflecting a sector-wide mood of consolidation rather than fresh selling pressure.

Earlier, Morgan Stanley and Bernstein pushed back against fears over Toshiba's HDD capacity expansion, arguing the market had overreacted. Their checks indicated an effective annual capacity increase of roughly 30%, in line with industry supply growth, while both Seagate and Western Digital showed no intention to follow with their own expansion. Despite this supportive view, shares gave back some of Monday's gains as the broader storage complex wavered.

Western Digital Corporation develops, manufactures, and sells data storage devices and solutions, including HDDs and SSDs for client, enterprise, and consumer markets under the Western Digital, SanDisk, and WD brands.
