Seagate Technology Inc. (STX) expects to take a $64 million non-cash charge to impairment of goodwill and other long-term assets to write-down the value of equipment it plans to sell.

According to a filing with the Securities and Exchange Commission, Seagate will take the charge during its fiscal first-quarter of 2010.

The hard-drive maker will sell equipment "related to certain research activities that have ceased," and is writing-down the assets to fair value less the cost of the sale.

Seagate doesn't expect the charges to result in any material future cash expenditures.

Seagate shares closed down 4.6% to $14.51 Thursday. The stock was inactive after-hours.
