Some try to work around the 504MB / 1024 cylinders issue by making a large partition using a friend's computer, Linux' fdisk, or something else. They use it for a day or two, conclude that it works, then post a triumphant article claiming that they found the Solution To Everyone's Problems[TM].
It will work... for precisely 1024 cylinders. The very moment the OS or anything else attempts to write something to cylinder 1025 through int13 calls, the write wraps around to cylinder 0. This cylinder happens to hold some of the most important data structures on the disk: the Master Boot Record, partition table, both FAT copies and the root directory of the first partition. Overwrite these and probably only a specialized data recovery company will be able to salvage your data.
Try it if you must. If you know exactly what you're doing, you can make it work using Win95. Sort of. The first error will be fatal. But please don't post any stories about it, recommending the procedure to everyone. The spectres of their valuable data will come back to haunt you.
