Problem

Solutions: If you can't use a drive on your hard disk after installing MS-DOS 5.0, and you don't receive the "Invalid Media Type" message when you try to access information on a partition, that partition is probably incompatible with MS-DOS version 5.0. To regain use of the partition, you need to back up your files and replace the incompatible partition. CAUTION: Do not use this procedure if you plan to modify your primary DOS partition. Otherwise, you might replace your MS-DOS files. This procedure describes how to replace an incompatible partition with a compatible one of the same size. Follow these steps to replace an incompatible partition: 1. Insert the Uninstall disk in drive A, and restart your computer. The Uninstall program will appear on your screen. 2. Follow the instructions to restore your previous version of MS-DOS. 3. Insert Disk 1 in drive A, type A:HDBKUP, and follow the instructions to back up the files on the partition that is incompatible with MS-DOS 5.0. (You can use a different program to back up your files, if you want.) 4. When you finish backing up the files on the incompatible partition, press F3 to quit the Setup program. 5. Remove the incompatible partition by using the same disk-partitioning program you used to create that partition. 6. Reinsert Disk 1 in drive A, type A:SETUP, and follow the instructions to reinstall MS-DOS version 5.0. 7. Use the FDISK to create a new partition. If you do not have an extended DOS partition, create one. Once you have an extended DOS partition, create a new logical drive. (Do not create a primary DOS partition.) 8. Use the FORMAT command to format the logical drive you just created. 9. Insert Disk 3 (5.25" disk) or Disk 2 (3.5" disk) in drive A, and type A:HDRSTORE to restore the files from the previously incompatible partition. (If you used a different program to back up your files, use that program to restore your files. Be careful not to replace your MS-DOS 5.0 files when you restore your files.
