Hey! friends today I wanna share an event of my life related to PENDRIVE which is a commonly used & known for data storage & transfer.The event I m gonna share can happen with any one who has lack of knowledge in the field of electronic items.So friend a tip from me don’ buy pendrives & sd cards from the induviduals who roam here & there holding them in their hands.Actually I was new in Delhi & was fooled once. I had bought a 128GB pendrive in Rs150. And was very happy after buying it that itni sasti pendrive aur itna zyada storage but when I came to my place & used it.In its properties it shows the 128 GB storage. When I copied files the files get copied easily but when I eject it & re plugged it every thing was gone.Actually the reality about these type of pendrive or sd card is they ae built in such a way that they have a flash memory of 2MB or 4MB which works in a loop due to which it shows in properties the storage space of 128GB, 256GB or whatever they say.this loop is also working when we copy files but it is working in a way if the flash memory is of 4MB the it is simultaneously deleting & copying the file we have copied. So when we eject & plug in again it doesnt show anything.So please dont fall for big storage in less price.This type of event is common in big cities like Delhi, Mumbai.One more piece of info.If you buy pendrive of any company from a well known store it will work & if by any chance it doesnot work that means the piece is defective & will be replaced.So Be Aware.Thnx fr reading.
