components of hard drive

Hard Drives will soon be available in a new format which might not run with XP. Currently the drives are manufactured in 512 bytes format which will be replaced by the 4k bytes format. The 512 byte format has reached saturation levels. i.e. it is becoming difficult to reduce its size further. Whereas 4k byte format has scope to reduce the size and increase efficiency simultaneously.
Experts in a discussion said that the industry has agreed to phase out the old formats by 2011. Except XP all other new operating systems are likely to support this new format. Some say that this new drive will still be compatible to XP but the data transfer speed might suffer.
