External HDD lost space after format

[ipo65]

I wanted to use a 160GB external USB hard drive with an old powerbook G4.the problem is that the Mac can't write to NTFS, so I used the disk utility that comes with OS X 10.4 to format it to HFS+ (Mac OS Extended, Journaled).

i don't why, but it reformated it to 74.8GB (the same space that powerbook has).
then I tried to reformat it back to NTFS to see if i get back the space - it didnt

i connected it to a windows 7 machine and used the disk managment utility to see if there is unallocated space on the hard drive - there wasnt

its showing 74GB and no matter how i reformatted it - it remained the same space
i even tried to use a program to low level format it (called, Hard Disk Low Level Format Tool, here a link to the web page - http://hddguru.com/) - it didn't help.

i ended up just formatting it back to NFS+ so the powerbook can at least use the 74GB for now until i find a solution

any help?

Which external USB drive is it? maybe running a manufacture specific tool to low level format the HD might help.

its actually just a regular old notebook Fujitsu 2.5 hard drive inside an external case, but i'll check their website, thanks for the idea.
i'll post if this helped
