Request to all My Jat Land Friends...
not to buy any Kingston 32 Gb Pen drive..watso ever they are going to give it to you only in 100 rupees....
as these are completely FAKE...
Only it has 1gb storage space.
Strangely, the program installed inside is showing 30gb even after you've formatted several times.
You can copied nearly 7x4gb files in it.
But you cant open any of files in OS(windows/linux).
All Kingston 32gb drives are FAKE.
And most of 32gb flash drives are also FAKE.
Do not buy or try. You'll be in trouble or headache.
This is not actually question.
This is a really WARNING for all USB flash drive users.
The Problems you can face after buying it:-
1.you can put 32 Gb data in it ...but you cant retrieve data from it..as it creates only and only image files of those not any data(written) on it.
2.It can corrupt ur windows and in 99% cases its YES.

Please also guide it to ur friends..

Thanks and Regards,
Jaglan

Bhai,,,aisa koyi tareeka nikal sakta hai ki hum Image se idea lagale apne data ke baare mein,,,,

When we are able to put 32 GB inside it ,,,atleast its there in the drive,,,,kam te kam bahar to biraan nahi gaya na,,,,,ab sawal uthata hai ki uski images kaise padhe,,,,,iska koye tareeka nikaalna chaahiye bhai,,,,,32 GB ka pen drive cheej to kasuti se,,,,bas thodi si modification ki to jarurat se,,,,,Data ki image bahar kaadh ke usne padh lyo,,,,shayad kaam chaal jyaa



1.you can put 32 Gb data in it ...but you cant retrieve data from it..as it creates only and only image files of those not any data(written) on it.

Next time when you want to buy computer hardware go to Nehru Palace so that people can save their time by not getting such a crap and jatland will save wastage of one thread if you want good things you have to pay.You won't get even poision for free.



If you buy pendrive from palika bazar you will face same problem cost will be hardly 300-500 bucks but if you get it from Nehru palace you will get replacement and repair warranty but cost will be many many times more you can get 8gb for 650 thre i haven't checked for 32 gb

Yesterday I also met one person who was selling this kind of Pen drives. I had jaglan's post in mind and I checked the pen drive immediately by storing 32 GB stuff in it... Lekin it could not store. So, I didnt buy it...

Bhai maine vahin par aapna Laptop Kholya,,,Pen Drive lagaya aur 32 GB Data store kar diya,,,,,,bhai Hairani ki baat thi ke,,,,32 GB data store to hogyaa,,,,,par jab main usne retrieve karan laagya to,,,sukki Image deekhi,,,sabat data ki,,

Bhai sachin,

This shows that racket of nakli thumb drive is strong and people are fooled everywhere. At least we hv examples of Delhi and Chandigarh with in a day.....

Request some technical gurus on Jatland who can update us... how these NAKLI pendrives are made and how come these people are making money even after selling it in 100 rupees or so.....

Lets have a serious discussion this time!

Well, I was so wrong in judging it to be another rumour downgrading 'Kingston' - the company. But Mr. Jaglan is right.

Look how coincidental it is... I met this bloke at The Boulevard (Hull City's home stadium)yesterday where I had gone to see Hull City taking on Aston Villa in yet another EPL encounter. And guess what, he offered me the very much infamous 32GB Kingston Flash Drive. I tried to shun him off but when he offered me 'live' data from Phil Brown's mouthpiece... I thought to give it try. Much to my own embarrassment he was right... I could hear Phil Brown in conversation with his technical associates. I was thrilled. But later due to some noise interference (caused at our end) Mr. Brown lost the connections and Hull City lost 0-1 to Aston Villa. It was a nice game and I bought the flash drive. As I moved out of the stadium I thought of 'playing' the recorded conversation again... and to my own amusement I found that I was duped.

Heard a similar incident from my Pakistaani friend here... seems like the entire Yorkshire is being targeted... especially us - the 'brown' Asians.

How I wish I had taken Mr Jaglan's advice seriously... I would have saved 40 Great Britian Pounds. I am on fast today:(!!

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,,,

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.

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.



This is really something very disappointing that we have not recieved any expert comment on this serious issue from any of the worthy member on this site and i know we have many Network experts here,,,,,,,

Sarkaar ko is ghatna ke upar ek commission baithana chaahiye

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.

Ajay you have shared amazing technical info which will benefit even a non-techie like me, thanks 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.



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



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.

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,,,,,

The Message given was "Cannot Render File"
Same message was given when the file was copied back to HDD and then played.

Kya kisi aur bhai ka bhi aisa experience raha? I hope this thread has been helpful....so refreshing it once more so that more people can read !!! :D


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.
