It happens often enough that computer crashes occur the minute it is turned on. Cutting the power and then turning the PC on will sometimes allow you to reach Safe Mode. This will buy you time to backup documents and programs. But what if you can no longer reach Safe Mode? The answer is DOS. DOS data recovery is useful when your PC will not even boot Windows.
DOS data recovery can be very limited in the choices it gives you in terms of changing file locations. If you want to backup to an external drive, you will need a DOS driver.
It is, of course, a good idea to have one ready BEFORE your PC crashes because how will you be able to get online to download it if you've already crashed? So surf your external drive manufacturer's website and download the appropriate DOS driver today!
Now, what if you don't have an external drive but only a CD-RW one? Try going to MS-DOS and accessing it? It is unlikely that you will be able to. Even if you have a CD-RW driver it may be next to impossible to find the software to make DOS data recovery work.
An ounce of prevention is indeed better than a pound of cure – so make it a habit to periodically create batch files for ALL important documents and programs. Store them in an external backup device, such as an external drive, disc, or floppy. If they are critical to your business, make two copies and store one offsite.
But what if, despite reading this warning, you still don't feel inclined to backup your files or even take tedious measures to make DOS data recovery possible?
Basically, you have three easy options in dealing with a denial of service response from your PC.
- First, you can buy a heavy-duty backup device. This normally comes with its own DOS driver, which you can use to try to salvage your work through DOS data recovery. If you buy such a device as a preventive measure, just make sure to remember where you keep the driver.
- Second, you can create drive partitions or use more than a single hard drive to hold all your data. This is a preventive measure if you don't want the hassle of periodically creating external batch files. All you have to do is use DOS Navigator to backup to a working drive. Note that partitions only work if your hard disc is not damaged physically.
- Third is the old reliable floppy. If your PC still has a floppy drive, and a floppy DOS driver that can still be read, then you should have no trouble with a backup command in DOS.
The lowly floppy drive may be undesirable in terms of storage capacity nowadays, but as far as being universally accepted by every OS, which includes DOS, the floppy can be a godsend when the worst happens.
