Unix vs microsoft?

If we have CD-ROM, DVD-ROM, floppy drive and TWENTY-FOUR (24) logic disk partitions on a single Windows system with a very big disk drive, how do we handle these drives per Microsoft's 26-letter drive naming convention? If it is on a Unix or Linux system, do we have similar problem

Unix vs microsoft?
As long as you are using NTFS in Windows 2000/XP or greater, then you can map the partitions as directories under an existing drive letter (typically C:). Otherwise, you are limited to 26... A/B for floppy, C for the boot partition, then usually D/E for CD/DVD, and 21 more for additional partitions.





Essentially, UNIX requires you to "mount" all partitions (and external devices) as a directories within the root, or slash / (which represent the boot partition)... so UNIX/Linux has never had a limitation.





The final question is why 24 partitions? The latest Windows and Unix/Linux versions can handle Terabyte drives without the need for partitioning.
Reply:Why so many partitions? Totally illogical.
Reply:I think in windows it would then go aa:\ ab:\ and so on, but I don't know how many drives you could have total. in unix(linux, at least) the cd and dvd wouldn't matter because they would be cd0, dvd0 or something like that. the partitions would be sda1 - sda99 or hda1 - hda99. I don't know how many it would support total either. but if you have a disk big enough to need all those partitions, you should get lots of disks or a raid in case that one disk goes out.
