How to repair it? Thanks! Re: If you plug out the USB harddisk without remove it in Windows. Sebastian Schneider21-Jun-05 22:04 Sebastian Schneider 21-Jun-05 22:04  It should still be recognized. Try replugging it into a different USB-port and into a different computer (using proper dismounting). This could be the solution to your problem. If it is not, you have probably killed the indizes or partition tables. That happens when you unplug an USB-HDD while it is writing. You may also have fried the USB-to-IDE bridge, which sits between the built-in HDD and your computer. You might want to try to use the Administration panel (right-click on the "my computer" icon) to re-partition the drive. That is the quickest solution if there is no important data to recover. If there IS important data to recover, try using a different USB-to-IDE bridge and/or plug the drive directly into a IDE-channel and try reading it from there. If its recognized, but not accessible, a disaster-recovery tool might help. AFAIR, SpinRite (www.grc.com) can recover destroyed indizes and tables.

Use the COM Port while using XP j*18-Jun-05 6:48 j* 18-Jun-05 6:48  I want to write a program in VB.Net which accesses my computer's COM-Ports. While using windows 98 this is no problem, because there's a DLL which I can use. While using XP this is not possible because of HAL (Hardware Abstraction Layer). I already know that with HAL, it is possible to access COM-Ports by open a file. The problem is that I don't just need the TXD/RXD port but also ports like RI or RTS. How can I manage this? (Maybe there are drivers who create a virtual COM port and translate it to HAL to use the real port?)

On XP, those I/O ports are restricted to supervisor mode (the kernel). You must use the serial communications APIs. Unfortunately this is one of the less-well documented areas of the Win32 API. To be notified when the Ring Indicator or Clear-To-Send (i.e. the PC's view of the other end's Ready-To-Send line), use the WaitCommEvent[^] API. Stability. What an interesting concept. -- Chris Maunder Thanx, closed j*20-Jun-05 8:29 j* 20-Jun-05 8:29  Thanks to you, I've now found a way to use the PORT.dll with WinXP as well, and it's nearly the same as with win89: You just have to set the outports to 0 at the beginning. Windows Update on XP Professional disturbs hardware? Vasudevan Deepak Kumar18-Jun-05 1:00 Vasudevan Deepak Kumar 18-Jun-05 1:00  Hi: Would Windows Update Service disable any drivers or devices if they are not signed?

Alexander M.,18-Jun-05 2:07 Alexander M., 18-Jun-05 2:07  I've never heard a thing like this. Windowsupdate does never change hardware settings if the user does not select driver updates from windowsupdate. Don't try it, just do it! Re: Windows Update on XP Professional disturbs hardware?

Roger Wright18-Jun-05 2:51 Roger Wright 18-Jun-05 2:51  As long as you don't accept any driver updates you should be alright. I foolishly accepted a new driver from Microsoft once for my wireless card, and it caused the card to cease working, and the computer to become unstable. Fortunately, XP now has the Restore function - you could make a restore point, then do an update. If anything breaks, you should be able to roll it back. As far as I've seen, there is no check for signing after you have installed a driver, and you should not have a problem with XP trying to remove an unsigned driver.

If its an addon PCI card check the chip name/model, go to the card manufacturer's website and download drivers. Re: USB Host Controller Driver?

I want to do it for win 95 and then I need win 95 ddk but it doesn't exist... I read that it did in one place but none other. Where can I find it? The PROgrammer Niklas Ulvinge aka IDK Re: BIOS drivers... toxcct20-Jun-05 5:37 toxcct 20-Jun-05 5:37  i think you also need lots of studies on hardwares to do such things...

The things I'll have to do is to do a driver that takes input from an input and then put it in memmory. Not to hard to do with a driver. I realise I don't have to do a bios.

Re: BIOS drivers... Niklas Ulvinge20-Jun-05 23:41 Niklas Ulvinge 20-Jun-05 23:41  NO, not for what I want to do... I want to take input from the serial port and threat it as a keyboard.
