Hard drive partition mess

  Pineman100 17:05 12 Mar 2006

I've got myself into a hell of a mess, trying to delete paritions on a hard drive. Sorry if this rather long, but I need to explain everything carefully.
I have a 60GB Maxtor HDD that I want to use as a backup drive in an external USB caddy. Somehow I have totally screwed up trying to delete its partition system and reformat it (probably due to stupidity and lack of knowledge).
Current situation: because fdisk won't work on a USB drive I have put the HDD into an old computer, intending to fdisk it from a Windows 98SE startup floppy. The drive's partition information that fdisk is reporting is as follows:
Part'on Status Type Vollabel Mb System Usage
C:1 A PRI DOS BACKUP 8 Fat12 %
2 NON DOS 58636 100%

I have tried deleting the non dos partition, but fdisk says it can't do it.
Basically, I want to wipe the entire drive clean, then create a single partition with a single logical drive in it.
Can anyone please talk me step by step through what to do?

hi pineman100...
if you goto the maxtor website and download the maxtor utility ...this will create a bootable floppy ....boot the old pc with the floppy and follow instructions to set up a h/disk .....hope this helps.Dave

Many thanks for that - I'll give it a try and report back tomorrow.

Is the non dos partition an NTFS partition?. You cannot delete a non dos partition if it is inside an extended partition you can use a utility called delpart to do this. read this and download the utility click here

The fdisk report doesn't show any file system for the non dos partition - that part of the table is just blank. But fdisk still refuses to delete it. I'll download delpart as you suggest and add it to my armoury in case the Maxtor utility doesn't work.
Many thanks.

As suggested by daxian, I ran Maxtor's utility. However, it reported: "Maxblast detects a non-Windows boot sector on your primary hard disk (I had disconnected the main system HDD so the only "live" HDD was my troublesome backup disk). Maxblast went on to report that it cannot delete partitions on disks whose boot sector was created by (among other things) Norton GoBack.
When I used this HDD in my last computer, I used it as a backup with GoBack. So I think this must be the problem.
I also tried running Delpart, as suggested by Legolas, but it reported that it could not find the HDD at all!
Has anyone got any other ideas please?

"GoBack creates it's own proprietary Type 44 partition. It takes over the disk I/O like a Disk Manager or Dynamic Drive Overlay would, and keeps its logs in its own partition. Many/most third party partition tools and many undelete applications do not support Type 44. This alone should be reason enough to avoid GoBack.

For the techs in the group;
Be very careful when dealing with Type 44 partitions. GoBack has made some highly experienced techs into very humble little boys over the years. It's fully capable of eating your lunch, and kicking your butt all in one shot.
DFSee is very good at managing GoBack partitions should you find yourself in the midst of a GoBack nightmare, it's your first download. click here
DFSee will allow Type 44 partitions to be converted to standard types. The demo version allows this conversion without the need of registration."

Here's what I have done: I found instructions on the Symantec website on how to use fdisk to remove the GoBack entry from the drive's master boot record (FDisk /MBR). I ran it, and afterwards found that Delpart was now able to see the partitions on the drive. I deleted both partitions (listed in my OP above). I then ran fdisk again to start afresh - however fdisk now reports "Error reading fixed disk".

Have I created an attractive Maxtor paperweight?

I don't need any of the old data from the disk - just cleaning and prepping it to use as a backup. As you guys suggest, I'll try Powermax again on it.
Thanks very much.

Maxblast 4 finally did it! I now have a cleaned, and fully useable USB drive for my backups.

As you have probably guessed, I think I'm living proof of the old saying: "a little knowledge is a dangerous thing"! But thanks entirely to all the advice on this thread, I've got there in the end.

A million thanks to you all.
