This tiny prog can unmount attached FireWire or USB drives.

Now I can remove my USB stick without the risk of loosing data (AFAIK PE lacks of this functionality or I just don't know how to do it).
There are more options such as device id or device name. Refer to the commandline output for the syntax of DevEject.

@Bart: I've adapted your checkdisk.cmd to fit my needs.

Forgive my ignorance, but should deveject.cpp be included in the deveject.inf to be copied to the PE build?

No, deveject.cpp is the source code and is included with the app in case someone wants to 1) use it in their own app, 2) just curious about how it works, or 3) modify it to do more or fix a bug and rebuild it themselves

Deveject.cpp is NOT required to run the app.

@slic:

Nope it's just the c++ source code of deveject. No need to be included into pebldr.

Changes:

- Startup menu added

Wow, thanks! Didn't check it with XPE, so I'm glad you consider my plug useful!

I'm totally new to this forum, so please don't be too harsh if this has already been pointed out elsewhere.

I've been using deveject for a while now, but there's a couple of things that still bug me:

1) Despite the world cup, i can't speak or understand German to save my life, let alone understand what the readme says, so I'd really apprciate it if someone gave me a hint as to the copyright and distribution of deveject. I'd like to distribute it, but if no can do then i'll only output info for users obtained from wmi and request them to eject devices.

2) Can anyone explain what the debug swith does. An example would be really forthcoming, as I've used the -v swith in all possible ways I could think of and nothing happens.

Regards,
IVAN

The readme.txt file says:

DevEject -- devices log out automatically, for Windows 2000/XP/2003 =================================================================
DevEject serves to log out external data storage units such as FireWire plates or USB sticks by program control with the operating system.

A closer description you find in c't to 16/03, S. 208.

DevEject.exe -- the executable program
DevEject.cpp -- source text in C++

according to http://world.altavista.com/tr

The fact that it was published indicates that he owns the copyright. Write to the author and see what he says about your desire to distribute his utility.

Use the links in the plugin's deveject.htm Help file to try to find the author.

You could also write (PM) to Kalonji at http://www.911cd.net/forums//index.php?showuser=2579 and see if he has a contact with the author.

@Ed_P

Thanks for the reply. I'll follow your suggestions and post the feedback on this thread.

I also found some other utils that do similar stuff with USB. I'll try them out before adding threads. Again, lots of stuff is in German.

I tried comipling the source with dev-c++ 4.9.9.2 and got the following error:

CODE

Compiler: Default compiler
Executing g++.exe...
g++.exe "d:\0316_208\0316-208\deveject.cpp" -o "d:\0316_208\0316-208\deveject.exe" -I"C:\Dev-Cpp\lib\gcc\mingw32\3.4.2\include" -I"C:\Dev-Cpp\include\c++\3.4.2\backward" -I"C:\Dev-Cpp\include\c++\3.4.2\mingw32" -I"C:\Dev-Cpp\include\c++\3.4.2" -I"C:\Dev-Cpp\include" -L"C:\Dev-Cpp\lib"

d:\0316_208\0316-208\deveject.cpp:323: error: (Each undeclared identifier is reported only once for each function it appears in.)

Execution terminated

however, when substituting

CODE

if (toupper(*s1++) != toupper(*s2++))

for

CODE

if (s1++ != s2++)

compilation worked.

I also run the app and no prob.

Hope this helps others that might want to start playing with the source, which I must say, is quite complicated!

Wow!! Great link ivan. Especially the part that states:

QUOTE

But Windows XP optimizes and bundles write accesses to pen drives only when they are NTFS formated, so NTFS is the right choice.

Furthermore NTFS stores small files together with the file information so they are written into the same flash block which is the best that can happen.

Interesting.

@Ed_P

To be honest, I'm not that concerned about flash memory sticks as much as wireless network devices using usb enabled with PnP (plug&Play). I get all my info (deviceId, name, etc) straight from wmi scripts and match the data from the registry.

The reason I'm after a util like deveject is that it's much neater and impressing to have a script do the removing of the device than having to ask the user to physically do it. I wannna take step by step, though, after I get a proper removal, I also wanna be able to mount it back (not needed for my purposes, but for the sake of completeness!). The catch is that when I use wmi scripts, these can only be used for Windows ME onwards, leaving win98 aside.

The documentation came in handy!

i believe Matthias Withopf, the author of deveject can be found at

perfwatch@withopf.com

if anyone is interested. I sent him an e-mail asking for copyright info and posed the question on the debug switch too!

Public domain

Roughly I think it means it has open access, anyone can use it, and no one can sell it or claim it as their own work.
