Same SD card when used by USB card reader IOCTL_DISK_GET_LENGTH_INFO reports 979968 sectors, but when used in Texas Instruments PCI Integrated FlashMedia Controller IOCTL_DISK_GET_LENGTH_INFO reports 979776 sectors. Why they are so different?

IOCTL_DISK_GET_LENGTH_INFO[^] does not return the number of sectors it is returning the length in bytes of the object.

Sir ,
Here i m introducing u my project based on embedded system ................
This project is basically abt learning RF Communication with the help of " BLUETOOTH USB DONGLE "......
bluetooth has it's own protocol stack and in which i m going to use only rf communication part .........i m interfacing this
Bluetooth Usb Dongle with microcontroller with the
help of usb socket ..................and joining these wires with the microcontroller
Now , I will burn the USB Code and Bluetooth Code in the microcontroller ........so that they will first read out the usb code
and enable it and then read out the bluetooth code
and then start my Bluetooth Usb Dongle and then i will Disable the AUTHENTICATION i.e. passkey funda from it i.e. either
by removing passkey or making it "0"...........so that it can be used by any bluetooth Device
now i m stucked in midst of coding only ..................i need usb code to enable usb and bluetooth code to enable my usb
dongle which is of " ENTER " company ...........with the help of usb socket ..........
So pls have a look for this open source code for both so that i can deal with my devices.................pls sir send me that code as soon as possible as i have no help from anyone because no one knows abt it
pls tell me sir...........pls mail it on my id atbaheti.baheti24@gmail.com
pls solve my problem .............

Hi All,
i want to develop a application which resides on mobile(mobile application)and runs on PC when connected.
Now to do this my phone memory should be detected as removable disk.
Can i have any mechanism(drivers to be designed) to make my phone memory removable disk when connected to PC
Please post ur help...

Your mobile phone USB device should report as mass storage class, which has class 08, and subclass 06. At the same time the class protocol should be also supported.

I currently have 6 Windows Server 2003 machines and 2 Windows XP PCs running specific tasks.
2 of the 6 Server 2003 machines cannot be virtualised, but I see no reason why the others cannot.
The question is what are advantages and disadvantages of virtualisation and how would I go about specifying hardware?

Well, it obviously would prevent you from wasting resources and energy. You might have to invest into higher-end hardware, though, especially if one or more of the servers have maxed their CPU loads. The main disadvantage: If that system fails, all VMs fail as well - you need redundant power supplies, networking, harddisk storage....
If you want to specify the hardware: see above. You need to provide CPU cycles for all VMs, as well as redundant hardware.
Cheers,
Sebastian

now i need to know some people who are realy want to help me.
i know my project is not clear right now but i will explin it later.

but now i want to get code that let me stor data from passport reader to the database.....

I doubt that you will get an answer. You might, but I doubt it.
For me at least to make a response other than this one, you gonna have to explin it now, in full, in detail.

I'm sorry ...
now i will explain my problem and i hope you help me...
i made my graduate project which is control the ports of country,
so it's apply on airports...
and i need the passport reader to input the details of the passengers
of their passport....
but i don't know how can i connect the passport reader device with
a PC and then with my project form.
i need at least to read the data from the traveler's passport by
the passport reader device to hyper terminal program which come with any
win-XP or to any text file....
i use (CM20xx) passport reader.

Your best bet for this is to contact the manufacturer of the CM20xx, via their website if they have one. Get the technical specs to discover what interfaces they have, together with details of any encryption / data encoding and schema they use.
It may turn out to be as simple as the data is read into a database, which you might be able to access.

Thank you mr- Henry Minute for your answer ..
but i searched about the web site but i failed..
if you have any information about any thing that help me to
connect the passports reader to the Hyper Terminal Or to any program
in windows i will be glad and i give you a small Kiss.

Well, gee, thanks! But I think I'll pass on that. 
Before I gave my last reply I Googled for 'CM20xx' and got several hits, none of which could be specifically attributed to a Passport Reading device. One of them, which did mention 'reader' had both a USB and a serial interface. There are lots of articles on interfacing to both of these using C#, however, that's not a lot of use unless you can somehow confirm that your choice has either/both of these.
Two things occur to me.
1) Find the postal address of the manufacturer and write to them, explain your situation and ask what help, if any, they can give you.
2) And you may have to do this if 1) doesn't work. Select a different reader, that you can get some information on.
That's all I got, sorry.
Good luck with whatever you do.

i am trying to write an app for an hotel to help manage inventory and accounts by taking records of sales from the cash register i want to be able to read the sales data from a cash register through either a serial port or network card from a pc i.e my app,any ideas?

Hi,

Get the manual from the manufacturers of the cash register to find the protocol used and what data is output.
Hook a PC with a serial port monitor to the register and see what is received when the register is used.
