my hard drive isbroken up into 5 drives how to make it one

Use fdisk.exe (partitioning program). Delete each partition one by one, then repartition as one drive using same program. Once finished with fdisk.exe program, then use format.com (formatting program) to format drive. Please consult HELP or DOS manual for proper use of fdisk and format programs. Both programs are run from dos prompt.

Note: fdisk or format program will delete all existing data on hard drive so be sure to backup important data before performing above procedure.

The programs mentioned above come with DOS (later versions), Windows 95 and Windows 98. You can also use partitioning software (like Partition Magic) from several different vendors (for a fee of course.... it's not free). Use google search engine to look for it. :)

Jerry K is quite correct but here are some extra points to consider:

The FAT16 file system (as used by DOS and Win 3.1) only allows partitions up to 2Gbytes so if you have a 10Gbyte disk it will be in at least five pieces. Win 98 defaults to FAT16 but allows you to convert your drive to FAT32 - after which DOS won't be able to read it. I don't know what the size limit is on FAT32 because I've never used it.

In my experience, the Win 9x versions of FDISK don't work very well. I once rescued an 8 Gbyte SCSI disk from the bin after its owner had declared it useless. His Win 98 FDISK said it was faulty but DOS 6.22 FDISK fixed it.
