Nov. 15: Dell Inc. says revenue will likely be hampered in the next few quarters because of shortages in hard drives. The company says it still cannot pinpoint the magnitude or duration of hard drive shortages because of the complexity of the situation.

Nov. 21: Hewlett-Packard Co. says supply constraints should start to ease by the end of the fiscal second quarter, which ends in April. But the company says the situation remains dynamic. "I've been on the phone with the heads of all four of our disk drive partners and I'm not even sure they have a complete picture about when they're going to be back up and running," CEO Meg Whitman said. She says the company expects to get more than its fair share of drives because of long-term relationships with suppliers, but "this is going to be pretty tough for the industry."
Nov. 22: TiVo Inc. warns of increased costs for hard drives in the current quarter.
Nov. 28: Seagate says it will hit the low end of its previously forecast range of disk drive shipments. Seagate now expects to ship 43 million units in the current quarter. In October, it had projected 40 million to 50 million units.
Nov. 30: Analog and mixed-signal semiconductor maker Semtech Corp. says it expects results to be hampered in the current quarter. It issues a quarterly forecast that is short of analysts' expectations for adjusted earnings and revenue.
Dec. 8: IHS iSuppli estimates that the flooding will result in a shortfall of nearly 4 million PCs — most of them laptops — shipped in the first quarter of 2012. The research firm now expects global PC shipments to total 84.2 million in the period, down from a previous estimate of 88 million. This would be a drop of nearly 12 percent from the October-to-December period, using iSuppli's estimate of 95.3 million PCs in the current quarter.
Dec. 12: Intel Corp. cuts its fourth-quarter revenue outlook, saying that companies are reducing inventories and microprocessor purchases because of shortages of hard drives.

Feb. 9: Lenovo Group Ltd., the world's second-biggest maker of PCs, says a global shortage caused by flooding is adding $5 to $10 to the cost of each hard drive. Chief Financial Officer Wong Waiming says the impact of the floods on hard drive production will "likely continue to affect global PC supply" into the next quarter and hard drive costs "will continue to stay high in the short term."
Feb. 22: Hewlett Packard Co. blames flooding for more than half of its drop in revenue, a 7 percent decline to $30 billion. HP says it decided to divert supplies of drives to higher-margin products. It expects constraints to continue in the quarter through April, but the effect on revenue should be smaller compared with the recent quarter.
March 29: Data storage provider Xyratex Ltd. says its net income in the latest quarter more than doubled, despite flooding in Thailand hindering its ability to meet customer needs. Xyratex, based in England, had warned that it may have trouble meeting its customer's storage demands because of a limited supply of certain disk drives.
April 11: Estimates from Gartner and IDC suggest that PC manufacturers have mitigated hard drive supply constraints. Gartner says there were moderate problems in selected markets, such as low-end consumer laptops, but "low PC demand was able to mask the tight (hard drive) supply overall." IDC says larger PC makers such as HP and Dell succeeded in managing inventory and absorbing price increases in the parts.
