Repairing damaged partitions on is a risky business. Even if you use the best toolkit and are absolutely sure in what you are doing, you are still risking your files shall something go wrong. Changes made to the damaged partition are irreversible; it is just too easy to overwrite an important system structure that holds vital information about your disk, files and data. Bottom line: it’s good to backup before performing data recovery. But is this really the best way to do it?

There is a different approach to do data recovery that is even safer. No need to backup and restore during the recovery. Instead of making a backup copy of corrupted data, you can simply take a binary snapshot of the partition being repaired, and attempt the recovery with different settings as many times as you need on this snapshot instead of the actual disk.

SoftAmbulance Partition Doctor by http://softambulance.com/ is one of a few data recovery tools that allow recovering a virtual image of a damaged hard drive instead of repairing the hard drive directly. The data recovery tool lets you create a binary image of the damaged hard drive, and works with the binary image instead of the real thing. The binary image is a big file stored on another hard disk, CD, DVD or other media. The technology is similar to making an .iso image of a CD or DVD disc, only SoftAmbulance Partition Doctor extends it to partitions or even entire disks.

The hard drive copy may be virtual, but any data you save from it is for real. SoftAmbulance Partition Doctor can recover your files, documents and other data from the binary image and put it on a healthy media. After that, you can attempt fixing the damaged system structures of the corrupted hard drivewithout taking any risk at all. Any modifications will be performed on the virtual image.

Don’t rush the recovery. Don’t take the risk of losing or corrupting your data. Create a virtual snapshot of the hard drive being repaired, and work on that snapshot instead of accessing the corrupted hard drive. This procedure keeps your original data safe, and ensures the highest level of safety during the recovery process.

SoftAmbulance Partition Doctor recovers files from damaged and corrupted disks and partitions and fixes damaged hard drives. The disk recovery product supports all 32-bit versions of Windows, and recovers FAT and NTFS formatted hard disks, memory cards, CD and DVD media, and USB flash drives. The evaluation version is available for free at http://softambulance.com/

If you have experienced a Windows “No Audio Device” error, it most likely means that your sound card is not installed properly. Even though other problems can cause this error, an improperly installed sound card is the most common reason. If the audio card isn’t properly connected in the motherboard or you do not have an audio controller connected, you will get this error. Also, it is possible that the device you are trying to use is not compatible to the motherboard you are using.
Troubleshooting the most common error
Here are a few steps to take to solve the most common error, an improperly installed card:
You will first need to find your audio controlling device or controller. This controller is what gives you the ability to adjust the sound for everything. From your start menu, go to your control panel. Then, go to add hardware and search for the hardware yourself. Don’t let the computer search for it automatically, because if it is improperly installed it may not be seen. Then, scroll down to sound devices and search for your audio controller. Check the properties of the device, and see if it is installed properly. If it isn’t installed properly you will see a yellow highlighted question mark beside the device’s name
? The best way to solve this problem is to uninstall your sound card and drivers. You will reboot, enter the bios, disable the onboard audio, game port, and midi. Then boot back into windows, go to add remove programs and make sure that any programs for the device was removed.
Next, you should reinstall the sound card and drivers. It is possible driver updates have been made since the sound card was manufactured and released, so it is a good idea to visit the manufacturer’s site and see if there are driver updates. Once you do this, restart the computer again. The problem is (more than likely) the default device in audio properties is still the onboard, you can select the creative devices and it will probably work, but it will be better to disable the onboard all together.
Uninstalling and reinstalling the sound card will more than likely fix your problem.
Other troubleshooting tips
If you are still experiencing difficulties, try these other troubleshooting ideas.
? If you think your sound card may be ‘dead’, before buying a new one, I would recommend borrowing one that is fully functioning from a friend, if possible, and installing that one to see if the error is in the card itself.

? Try using a different PCi slot, that way windows may detect it as new instead of trying to reconfigure it on the slots its currently on. This can also help you to determine whether one of the slots are bad.
? If you have an onboard sound card but are trying to use a sound card you bought separately, ensure the onboard one is disabled.
Always ensure the sound card you purchase is compatible with your board. If it doesn’t say on the packaging, do a little research online prior to the purchase.
