Data storage outfit

McData

(MCDTA)

lowered its first-quarter guidance for the second time Thursday, saying it now expects a wider loss and lower revenue than

predicted just a month ago.

The company is now planning to report a loss, before items, of 4 cents to 7 cents a share on revenue of $62 million to $64 million. When McData first took down its projections in March, the company predicted a loss of 2 cents to 4 cents a share and a top line of $73 million to $78 million. Originally, the company had been expecting to break even, or even post a profit of as much as 2 cents a share for the quarter.

McData attributed the even lower guidance to additional order reductions from its largest customer. The company plans to report its results on April 18.

In a press release, the company said the revenue expectations "suggest that McData is being adversely affected, in part, by delayed IT spending in the high-end sector of the storage market."

The Class A shares of McData were dropping 23.2% to $9.35 in Instinet trading after the closing bell. The stock ended the regular session at $12.17.

Not surprisingly, other storage stocks were caught in the downdraft, though they weren't hit as hard as McData.
