Other storage companies also lost ground in heavy trading.

WDC said this morning that its second-quarter results would be negatively impacted by competitive pricing pressures in the desktop hard-drive business, as well as by product-mix and cost issues associated with the company's last rollout of desktop drives.
One analyst said there were pricing pressures in the high-end SCSI drives about six months back, and that pressure has dripped down into the desktop market as well. He stressed, however, that this is not a demand issue, but rather the result of oversupply.
"The demand is awesome, but despite that, too much supply is hurting profitability," the analyst said.
He added that much of the back-up will get corrected in December because, seasonally, it is a strong quarter. Additionally, the seasonal up-tick is expected to be followed by another strong March quarter. "This should be cleared entirely or to a great extent by March because the OEM business is still very robust," the analyst said.
Some companies have cut back production slightly to ease the congestion in the channels--there is about six weeks of back-up there now, the analyst said.
However, the analyst pointed out, once things become less congested by the end of the March quarter, another seasonally slow period is expected to begin.
