Hi,
Do you know locking/unlocking capability of your hard disk? If not, read following.
Every hard disk has inbuilt controller, called ATA controller. ATA stands for Advanced Technology Attachment or AT Attachement. ATA is the standard protocol to interact with the hard disk. ATA protocol has several commands using which hard disk can be locked or unlocked.
This lock is the hardware lock. Once hard disk is locked, you can't read/write from your hard disk, until unlocked. Once it is locked, all commands to hard disk will be aborted, except commands for unlocking and some special commands.
Almost all modern hard disk support security feature. By default security feature is disabled. It needs to be enabled and then only hard disk can be locked/unlocked. Some older hard disk might not support this feature.
I have created a utility, completely coded 'C' language, to lock/unlock hard disk.
For more details and downloading this utility, visit Lock-Unlock Hard Disk[^]
Thanks,
Sandeep B. Vaniya

This seems to be good material for an article.

I will publish article for the same on code project.
Thanks for your suggestion.

What about the last article you wrote here on that utility?
Make sure you include the source this time... 
|
|
|
|

I had published article after Andersson's suggestion. But you guys might not like that article so I have removed it.
I am already in my home with my bat and ball.
I am wondering that you are still searching for source code.

Hi Sandeep,
I thought your last article was a good start. There were perhaps a few details missing that would have added to the knowledge it imparted, like the nitty-gritty details of the port numbers used and the protocols for use, (e.g do an "Out 70h, al" followed by reading 10 bytes from 71h, using the 11th byte as the result-code, blah-blah) but overall I found it to be a highly interesting concept - It's been 10 years or more since I played with DOS programming, and always found it to be a challenging medium to write ASM code under, what with the 64kb segments and all the 'fun' they entail.
So please, if you feel like grabbing your bat & ball and coming back out to play, I'm sure a lot of the other kids would be interested in what you had to say.
Oh no, I'm not still searching for the code, I've already got it. I already know which ports were used, as do about 1/2 a dozen other people that downloaded the source I posted for you. It would just be nice to see the (well commented) code finish off what has the potential for being a really interesting article. Remember, no author in the world won a Pulitzer Prize for a piece that was classified and not released to the public....

In winxp int8 not time interrupt How can i get it?
|
|
|
|
|
Windows doesn't allow you to hook interrupts from user mode. If you want to do things with timers, see SetTimer (if your timing doesn't need much accuracy) or timeSetEvent if more accuracy is required. There are also system timers you can use by calling CreateWaitableTimer, which I believe is the only approach in kernel mode.

Return your system to your computer dealer and buy another one that comes with the disk. 
So the creationist says: Everything must have a designer. God designed everything.
I say: Why is God the only exception? Why not make the "designs" (like man) exceptions and make God a creation of man?

For linux you can create a livecd of your entire os + applications. For windows you can use bartpe to do something similar but you do not directly get all the applications.

I assume that you want to make a copy of your OS installation disk. You can use Alcohol 120%( http://www.alcohol-soft.com/[^])
There are many other such softwares. Whichever one you use, select the "Copy DVD" option.

I don't know about vista but I have not seen any copy protection on any Microsoft CDs prior to that OS and even it it had some you can slipstream you own copy without any difficulty. So just about any cdrom software will copy the OS disks.

Is it possible to get two wireless routers to talk to each other wirelessly?
I'm having trouble with my DLink wireless USB key and am wondering if I could use a wired connection to one router ->wireless to other router -> wired to telephone line.

Use a repeater.
Either you buy a repeater, or you can buy a bridge/router/gateway or accesspoint with repeater functionality. You'll have to read the specifications.
|
|
|
|
|
You should be able to, and it would be easier if both routers were the same brand/model. You would need to set one up as a bridge/WAP (without any "router" functionality).
However, why do you have two wireless routers that are both set for wireless operation?

My employer loaned me one when I first got broadband as I work at home occasionally and I've just been given a netgear one as part of signing up with virgin media. Only one is active but I was hoping the wireless connection between two routers would be more stable than the DLink USB adapter I'm currently using.

Dear all
I have a set up for a multithread application that works with Sound Card and it uses Socket Connection. this set up works perfectly on a computer with these specifications:
motherboard: ASUS P4P800-MX Model
Processor: Intel Celeron CPU 2.53GHz
Memory: 512 MB , GEL brand
Hard Disk: 80GB Maxtor , IDE
Sound Card: Creative Sound Blaster 24 bit
but when mentioned setup run on another computer , this application occur many different exceptions e.g. some times some Icones hide or access violation.
second computer specifications:
Motherboard: ASUS P5GC-MX/1333 Model
processor: Intel Pentium D 2.8GHz Dual-Core Processor
Memory: 512 MB , Kingstone brand
Hard Disk: 80GB Maxtor, SATA
Sound Card: Creative Sound Blaster 24 bit
I was changed OS, RAM ,Motherboard BIOS , Power supply, Sound Card and used another VGA ... but the problems remain.
the application wrote with Delphi7 .
any body have suggestion?

Really? What IP address and port does it open on the sound card? 
Anyway, you could have a thread maxing out and monging the GUI. Whst the CPU usage in task manager?

We need to install a network drive on the cheap.
We want to put a 500gb drive on a network so that the users can view/write to it as a network drive.
The only spare licenses we have are Windows XP Professional and Windows 2000.
Windows XP Professional only allows 10 concurrent users (we have around 80).
Windows 2000 only sees 127gb of the drive (connected via USB 500gb can be seen - but hey who want to run a network drive on USB?)
Any suggestions?
(And yes we are total cheapskates  )

Ubuntu Server (i.e. "Linux + Samba"). Easy to setup, Shares can easily be administrated, even over a Web-Interface AFAIR.
Otherwise, try partitioning the volume, if Win2000 allows that, or try to find a custom driver.
Cheers,
Sebastian

(Slipstreaming SP4 into an W2K Disk will enable 48-bit addressing and, if the BIOS supports it, allow you to allocate the whole bunch to one partition... supposedly)

Thanks - I will pass this on to the hardware/networking chap - looks promising

Buy a NAS (network attached storage), or build your own[^].

Thanks.
In the end the network manager decided to put 120 gig hard drives into a cheap windows 2000 server box.
What you managed is very impressive and I must say way out of my hardware ability - hats off to you.
