How to avoid losing data if windows crash?

When the OS crashes, it is very unlikely the actual data on any drive is actually damaged. However, what is more likely is that you might have a hard drive failure or the index that tells the OS were all you files are located might be corrupted. So while the data might still be there, the OS might not be able to find it. There are several software tools that assit in recovering from this problem. Also, you can often remove the hard drive, and make it a slave in another computer and recove the files just fine. However, your life will be a lot easier if you backup regularly. The cheapest way of course is to burn to a CD or DVD regularly. A better way is to buy an external USB or Firewire drive that you can make scheduled incremental backups to. Better yet, buy a network hard drive (NAS) drive that connects to your local LAN and that anyone on your home LAN can backup to. While Windows includes backup scheduling tools, it is anything but intuitive to use. You can purchase inexpensive backup software that will backup your files to another drive regularly.

Yes of course. But, as you said about the case of a windows crash...these thing happen mostly due to malwares like spywares or viruses. So these viruses can even affect your data in E and F drives. So a good soultion is to first make a list of important data that you cannot recover from some other resources easily and calculate the storage space required by them in all(total) and accordingly buy some ReWritable CDs or DVDs and take regular backups of these files regularly. So you can atleast hav at least 95% of your data safe in case of malware attacks. As far as your concern for data in drives E and F, these partitions are not affected, 'coz windows is installed only in one drive (C in most cases), so a crash wont affect other partitons(Drives). Bye...Best of luck.

Back up your info on an external HDD

yes because if you have the hard drive partioned in two like me the data you have in other place than your system drive (where windows is installed that data will be intact unless you are using a file when it crash

If the OS crashes and it is truly a software issue (most of the time it's hardware related); you can always buy another hard drive and use that for your new windows installation. your second hard drive can be a slave and you can still access all of the data on it. The data will not be in any danger, its just sitting on the hard drive and as long as the drive isn;t damaged, you'll be fine.

you most kepp saving your work every time you do something with it. that is the best way to avoid losing info.

BY DATA YOU MEAN THE OPEN USER-FILES YOU ARE WORKING ON. JUST UPDATE DATA TO THE HD AS OFTEN AS YOU CAN. ANYWAY, DATA IN MEMORY WILL BE LOST. OR MAKE THE RIGHT CHOICE: SWITCH TO LINUX.

It is always good to back up important documents in case your computer ever crashes. There are different ways to do this. The easiest DIY method is to save data to disks or a USB drive.

If you are worried about it copy your important files to a disk every day or something and keep them around. . I dont think so.
