Windows 7 - Unable to partition

I have a seagate FreeAgent Desk that i partitioned a 50GB partition and formatted it to HFSj for my mac. Now when i try to delete it under disk managment, it doesnt work. It says

What does that mean and why cant i partition it back to the 1.5 TB (Delete the partition)

Also iv tried EASEUS Partition Master, that wouldn't work either. It would say it worked, but when its done, it doesnt say unallocated, it says Other for the file system.

try a bootable Linux disk or Hirens boot cd any thing like that and try deleting the partition that way

Suggested many time in this forum. Always back up first.

GParted -- Live CD/USB/PXE/HD

Neither of those worked. It wont let me format either partition either i just found out.

have you tried to use disk wipe and write zeros to the whole drive and start from scratch

I cant, because all my data is on that drive and i cant back it up anywhere because it is my backup drive.

If you delete the partition - you will lose your data.

Paragon Partition Manager Free Edition

Si I notice you're recommending Paragon now instead of Partition Wizard.

What are the advantages of Paragon over PW? I am still using PW to help with copy operations and it seems to work every time.

After all, the one really big Copy disaster in the past month was when she used imaging software instead of PW, resulting in the Not-Geniune fiasco.

So I'm reluctant to let go of PW which you turned me onto in the first place and has now helped extract 150+ dual boots with almost total succcess, by my rough count.

Paragon is useful for resizing Extended partitions.

It also supports ext2, ext3, ext4 , and some support for Apple .

It depends on the task in hand.

There have been several issues with PW - not just that one - often the OP has been saved by guidance from here. It is very good for a freebie. It is far from perfect. There have been one or two recent cases of data loss thru incomplete operations.

PW is no use if you are not using FAT or NTFS.
