i have buy a pen drive of 16 gb. But it can't store data more than 30 mb. After formatting it still show 15gb. I want to know how i can know the real capacity of my pen drive.

As i hear that in market there are fake memory pen drives come, then how we know that it is fake or real?

@jcksn...
If you had bought pendrive recently... then you can approach the store to find out the Prioblem...since it's under warranty...

This is the first time iam listening about the fake pen drives... do such things exist in market...?
28 Aug 2008
Silly suggestion - but worth a try.

Try formatting the pen drive and try storing stuff in it again. Might work.

I don't think you will get total 16GB of memory space to use.
It took some memory space for the ratio is 1/10 mostly.
In our PCs also for 40GB HD, we never get complete 40GB of memory but somewhere between 36 to 37GB. Same case here.
So I would say, enjoy 15GB😀.

Ohhh..I thought after formatting he is able to use whole 15GB.
Then its weird.
Contacting a seller is the best option.

What if I look at the 40 GB this way.

Let us suppose by 40 GB the manufacturers mean
40000000000 (40 X 10^9) bytes of data
which is equivalent to 39062500 KB if i divide it by 1024.
Again if I divide it by 1024 I get 38146.97265625 MB.
Again dividing by 1024 I get 37.252902984619140625 GB

which is what your PC shows for a 40 GB hard disk

This is related to our discussions here:
https://www.crazyengineers.com/forum...rotect-error-my-1gb-moser-baer-pen-drive.html

To know whether the pen drive is fake or not depends on WHERE you get it from. Also, look at the price. 16GB of flash is probably relatively expensive at the moment (about $65 dollars) and if you got it cheap, then something fishy is up.

Unfortunately, the only other way to know whether the drive is fake or not is to physically test it.

Its best to just buy from shops and make sure there is warranty.

Jckson,

Gone through all posts.
What i suggest on all...
1>Go to seller & simply presuurize him to replace.
2>Maybe 30mb data will be a reason of its corrupted EEPROM.
3>Ask them to let you show around 15.3Gb of space as it will be or ask them to copy anything on it above 30 Mb.

Hope you will find your solution

It's not type fake storage device,
But many times in Company Manufacturer some device not properly made or configured so if your pen drive is branded then replace it to company

If not then buy a branded pen drive because they give life time warranty

hey jackson ,
i think i may help you..
actually pendrives are usually made up of capacitors(not real aluminium spinddle)
these capacitors are used as flash memory as charge is stored in there
in market capacitor can have (at max) 4gb of storage capacity
to make larger size pendrive we connect the capacitors in series so if one capactior fails(or is of cheap quality)others follow..
you will encounter problems like this either your data is corrupt or it is not shown at all(but you find size equilent)..
so
1. never buy pendrives above 4gb of storage(at least for a year or so)
2. always look for serial no on your pen-drive(tell me the distributor i'lltell you where to find it)
genrally this is escaled on your pendrive's metallic part (the one that is plugged into your pc)

pendrive viruses are mainly activated by autorun.inf . to reduce the problem disable autorun feature(autorun is different from autoplay).

read more about autorun problem here and download the registry crack for stopping it at the end of the post.

also, use autorun eater . get it from here for free. it will automatically kill malicious autorun.inf files in the usb drives.

additionally you may also use the free panda usb vaccine and use it to vaccinate your drives and usb drives. download from here

follow the steps and you will be relieved from most usb drive related problems.
also take care to scan your usb drive once before using it , with an antivirus.

recently a lot of news about fake pen drives.
i have heard that fake pen drives contain software which increases its storage capacity but its fake capacity.
once u format pen drive, it contains no software in it, hence its capacity reduces to a great extent.
these pen drive are available without any warrenty so we cannot claim anybody later

Yes fake pen drives do exist.But in your case a 16gb pendrive is providing 15gb space,what more you want.Its working properly,for example a 2gb pendrive provives space of 1.88gb.

Hi, Simply i am giving you the solution that 'Change your pen drive' otherwise if u want to try to recover the pendrive,it will eat your valuable time. I think the pendrive name is Kingston,because most of the fake flash drives found on that name(Chinese). The operations that can try to do recover are

--Formatting the Pendrive was of no use(even 100 times).
--Disk Check utility to see whether the bad sectors could be recovered but the program used to hang on initiating it. It will consume ur hours of time,but can't say.
--On opening the pendrive we can find the PCB was in a pretty bad condition,It had a 2GB RAM chip and was patched in firmware to make it look as it was of 32 GB or 16 gb or something
--Many Hidden system folders with random names having files more that 2.5 GB of size appeared randomly and you cannot delete them.
--so on......

Better to dont buy at out side including ebay(may be fake).
Try to buy the pendrives at reputed showrooms.

May be you have bought chinese pen drive.
Some chinese pen drive have capacity upto 32GB But can store only upto 1 or 2 GB
So go for Iball,Transcend,Moserbear,HCL etc.

ofcourse the speed can never be equal to the actual ram u are absolutely right, but it was useful in case u need for example 2 gb ram to run any application and you have less than 2 gb
