Intel X25-M 34nm firmware update triumphs, then fails hard
"In the most unfortunate of circumstances, many critical problems ensued right after Intel released the update and enthusiasts began the flashing process. The company quickly pulled its TRIM enabling firmware update and software package when reports abruptly came in of bricking drives under Windows 7. For those unhappy campers left in the cold after a promised 40-percent sequential write speed boost, Intel gave its short official statement to Engadget on the matter:"
“Yes, we have been contacted by users with issues with the firmware upgrade for our 34nm SSDs and we are investigating. We take all sightings and issues seriously and are working toward resolution. We have temporarily taken down the firmware link while we investigate.”
