bhai naraaj kyun hogya,,,,ya to hakikat se ke Singpure aalya ne Singapur basaya thaa.....puraane time mein ve rakbe di diya karte ne,,,,,,nyu e ek be Singpure aalya ne rakbe mil ge the,,,ar daakiya ne naam dhar diya Singapur,,,,,,
yu to bhot aachha hoya ke aaj aura ki bi GK badh gi,,,,ar vo Mr. Ch. Jaglan bhai ne thread shuru karya se na Civil Services aala,,,jyaant aur bi jaruri se GK ar current affair ki baat batana:rock

On Serious note:D,,,I have one query,,,,
Jaisa ki is Pendrive ke baare mein bataya gaya ki "it can store 32 GB Data in it but problem pop up when some body tries to retrieve it because the data get converted in to Images",,,,,,
Mere dimaag mein ek idea aaya is 100 rupees aale pendrive ka sahi istemaal karan khaatir,,,,,kyu na hum nyu kaara ke usme bheetar 32 GB ki Images store kardyaa retrieve karti haan bhi Images deekhengi,,,,,,
Bhai 6-7 Hindi ki Film store to kari jaa sake se naa,,,,,bata 100 rupeya mein baat banan laag rhi,,,
Sangwan I think its feasible to do so,,,,can some expert through some light on the innovative idea given above by me
Sachin bhai sarvottam idea.... mein kal uss ladkey ko dhoond-ta hoon jo ki yeh pendrives bech raha tha kuch din pehle..... agar aisa hua toh mein uss se pen drive le kar iss experiment ka Proof Of Concept (POC) kal hi kar doonga....aur apni report bhi ASBP highkamaanko soump doonga....
Yeh work-around iss samasya ka sahi samadhaan ho sakta hai...... !!! :rock
भाई माहरे ऑफिस में भी आया था एक 32gb पेन ड्राइव बेचन . मेरा एक दोस्त 80gn HDD खरीदना चाहता था, मैंने उसे फ़ोन करके पूछा, भाई लेन है के, पंद्रह सो मांग रहा है, हजार तक दे देगा, वो बोल्या ले लो.
मैंने बात की और छः सो की दो देने की बात हो गयी. वो बोल्या सर चेक कर लो, मैंने ड्राइव लगाई
उसे फॉर्मेट किया और एक डीवीडी मूवी उसमे कॉपी की. मैं उसे पैसे देने ही वाला था, की मैंने मूवी को प्ले कर दिया. वो नहीं चली. मैंने दूसरी पेन ड्राइव में भी चेक किया, वो भी नहीं चली. मैंने नहीं ली. उसने कहा सर कल नया स्टॉक लाऊंगा.
आज इस थ्रेड को देख कर सोची, चलो मैं बवकूफ बनने से बच गया.
Praveen bhai mere khyaal se to Movie chal jaani chaahiye thi,,,,,kyonki Image store karne ke baad Image hi retrieve hogi na,,,
Sangwan bhai is also carrying out some serious trial on these 32 GB pendrives and he is very hopefull of a positive result,,,,,shayad 2-3 din aur lagenge trial karne mein,,,,
Sangwan,,,trial theek chaal rhe se na bhai,,,,,
Hi,
There can be three issues regarding such fraud.
1) Confusion with storage unit---------------------------------"b"-- bit & "B"---Byte ( 8b=1B).
2)System Design issue-------------------------------------------Linked with project design
3) Memory & Microprocessor design issue Chip-------- linked with Semiconductor Comp.
Confusion with storage unit:--
Most of us know about this that 1Byte=8bits, letter "B"(Capital) is for Byte & letter "b"(small) for bit so some online seller can make you fool.....in their ad. they can write 8Gb for a 1GB Memory..
System Design issue:-
What is in a USB pen drive??
USB connector===>Microcontroller chip===>NAND memory chip
USB connector have 4 pins( 2 for power supply( 5Volt & Gnd).. 2 pins for signal ( technically known as D+ & D-)), PC provides 5V to USB devices.
Inside the memory chip there is a voltage regulator chip to convert 5V supply to a 3.3V or 2.5V depending on Microcontroller & Memory chip
There can be two places of error, One Microcontroller & IInd Memory chip.
1) Error with microcontroller (To understand this one need to know USB protocol, I m not explaing all but in small & only relevent) When u connect any USB device( nay device), Microcontroller talks with PC ,this process called Enumeration, in this USB device send data about that device, eg. what type of device, comp. name, product name, Driver location and lots of other information.. and all this data is programmable & stored in Microcontroller.. telling size of Pen drive is also part of this Enumeration. By mistake or fraud one can even show a 1000GB pen drive for a 1GB.. ...that can be happening here... 32GB fake for 512MB/1GB
2) Error with memory Chip:-
This is Storage where pen drive store data... one can format "FAT/NTFS" depending on Microcontroller's firmware..
about FAT & NTFS, a OS engineer can explain better then me.....So related to this Fraud.. one can solder smaller memory & in Microcontroller Programed it a bigger value..... "That is happing here".. if some one open this fake drive & check Memory part no. Google.. that chip will be either 512MB or 1GB.... what is know to "embedded product designer"
So to buyer of this FAKE pen drive Plz try to put small file & read back... note down biggest file u stores & also retrieved...that is actual size of ur pen drive.
One example may clear this issue, in 2001 one my Project was "USB Data logger"..at that time there was nothing on Google search .
I was using 256KB memory in my design ( At that time 16MB was biggest size available)... In one day I was playing with source code of enumeration process to display my name as Company name, I don't remember what I did but when I connected to PC this was showing 64MB as memory. but when I was writing to this more then 256KB , data was overwritten ( we were not using any format like FAT or NTFS) so we were lossing all information. But if one is using FAT/FTFS then ur data might be corrupt but there will be information about File, like file name, date,file size.. again an OS engineer can tell explain more on this.
Memory & Microprocessor design issue Chip:-
There are very rare chances of some issue regarding Semiconductor design.....very long to explain.
In totaly non technically explanination..
There is house 32 rooms and there is board at gate to tell what is inside room-- u can put some thing in room & write down on board.. get back & wtite there.... say that is your original 32GB pen drive.
One fraud person made only front wall & placed 32 Gates with board ( to log information about what is inside). When you will count, u will see 32gates & you will assume that there are 32 rooms. .. but actually there is no room ( or say one room to show customers).......-- This is about a 32GB fake drive.
