Hi friends, I want to personal opinion about Lenovo F309Tb hard disk, my computer storage reaches maximum level then I brought the hard disk from local retailer as need to store my editing software files in it .at first the hard disk works good. When it reaches to1 Tb starts lagging and the speed of it to decreased, after one year when I connected the hard disk to my computer it say the disk is corrupted and I loose all my old pics and important dates.
