1. How is the Maxtor formatted?? FAT32? NTFS??
2. Under Windows can you see ALL files in the 200GB data and read/write OK?

It might be a good idea to do some repairs under Windows to check the HDD is 100% OK rather than Disk Warrior on OSX.

The Maxtor is probably formatted with NTFS, just as it shipped from Maxtor.

One thought I had is to copy it off to the Windows PC (good idea anyway), share the folder, format the drive on Windows, see it work again on the Mac, and then copy the data back using the Mac from th ebackup across the network.

I think you have solved your problem yourself. I would add that when you are done you may want to consider reformating and repartioning your drive with one ntfs partition and one fat32. As as far as deciding what is the right size of each partition goes the only downside to fat 32 is that it has a 4 gb file size limit so it would not be good for things like big movies or big compressed  .zips or .rars. Windows,however, can read and write to it without any other hitch as can MAx OS X .  The other plus is that you are much less likely to have mft corruption type issues such as you are llikely experiancing now.

my maxtor format is NTFS and it can read/write on windows with full dat.but in Mac OS,it show no data and space available is 300GB(weird right?).

As I was saying, to avoid this in the future, repartition the drive with a fair amount formated to fat32.

Johnriptest - OSX CANNOT write NTFS formatted partitions and has problems reading them too  .. this is the reason you see a 300Gb volume with no data under OSX.

You have 2 options.

1. If you have an Intel Mac you could install BootCamp or Parallels and access the drive from within the Windows OS.
2. Try MacFUSE a special add-on for OSX that allows NTFS read-write. I have heard that it works well but have not used it myself.

I have a sneaky feeiling you may be dealing with a permissions issue.  If, for whatecer reason, OS X has decided you have no rights to the files and folders, poof, they're gone.  Put the unit back on the Windows PC and check.  You may have to temporarilly disable Simple File Sharing to easilly see; but, right-click on a folder and choose Sharing and Security.

i don't know but when i right click to get info of my HDDbox in Mac OS,my permission is read/write.
how can i have a no permission on this HDD?

Davis McCarnOwnerCommented:
NTFS has permissions for each and every file, folder, and volume.  OS X does too and would almost have to support them on an NTFS drive.  In Windows, for example, if I require a login and password to access a folder, anybody else cannot even see what exists; no subfolders, files, nothing.
You need to check those permissions on the Windows machine, not the Apple.

open the disk utility then repair the drive permission. you might want to just boot from the boot CD/DVD (put in the CD start up holding C) that came with the mac and repair the harddrive and the permission off the CD /DVD so that way it will most likely fix the issue that you are having. if that does not work run the hardware diagnostic off the CD/DVD (to do this hold down D at starup) it will tell you if there is something wrong with say the computers memory (i think it also checks the S.M.A.R.T on the drive) that might of caused the issue in the first place.
