Hard Drive Partitioning

By banzai ·
I had a 425MB hard drive that I had partitioned using Unix420 partition facility. I made a 125MB partition for Unix operating system and two more partitions for DOS with a primary partition of 220MB and a secondary(logical) partition of 80MB. When Irebooted I booted from a floppy and made DOS primary partition as the active one to boot from instead of the UNIX partition. When I booted to DOS from the hard drive, I ran fdisk and by choosing the 3rd option for deleting a harddrive partition, I deleted the UNIX partition which was listed as a Non-DOS partition. But when I restarted the computer I found the both the DOS partitions were there when I viewed them in fdisk but I was unable to access the 125MB of the UNIX partition. I also tried to boot from floppy and run the UNIX setup again but I was unable to revive the lost partition. I also used utilities like Disk Manager but without any success. The way is the I should use Disk Manager and do a low level format on the hard drive but Ihave got data on the

In recovering the data you will have to use Norton Disk Utility,otherwise you have lost the data
Choosing option 3 you are given a choice on the next screen of which partition to delete,by partition and you selected the delete the unix partition onthe screen.You cannot access a deleted partition

Try re-creating the Non-dos partion again either using UNIX or fdisk. You should be able to see the non-dos partion from fdisk. Alternatively install NT work station on one of your DOS partion and run disk administrator

Or use a disk utility likepartition magic.

Good luck.

DOS can only see 1 extended partition. It may be broken into several LOGICAL drives, but, you can only have 1 Extended partition. On the assumption that you want to use the other 125MB for DOS, you will need to
1 - move your data off the 80 mb partition to your 220 mb partition.
2 - run fdisk & delete the 80 mb partition
3 - reboot (yes, you should reboot)
4 - run fdisk and create a new Extended partition of 205 mb (80 + 125)
5 - reboot
6 - format the new partition as drive and you are ready to go.

Best of luck to you,
Jeff H.

I have found a utility called DelPart.exe to be really useful. It seems to do a much better job of actually removing unwanted partitions. This may help you too. It can be found in various places by searching the net e.g. http://www.esc14.net/troubleshooting/files/pcfiles.htm
