Sector size in new HDDs influences on images and performance


Today I received an email from HP on my notebook that informs the need to include in the images a KB from Microsoft or then change formatting even in Linux!!!

The document is attached in the post, but the explanation is, at least, intriguing. I was impressed to know that wasn’t disclosed that this problem exists in a more extensive and was not available on Windows Update.

The problem is that industry HDDs changed the sector size of 512 bytes to 4 Kbytes and simply not advised manufacturers that optimize chipset and BIOS for working with blocks of 512 bytes, which can generate a slowness of absurd 300%, mainly in the performance of Windows XP or newer SOs when installed by image.

Worth reading, even if you don’t have an HP equipment since the KB982018 applies to any equipment.
