[ale] expansion drive

[n4zm at mindspring.com (zeb)]

All:
    I have a Seagate portable expansion drive that is not recognized by 
Slackware Linux 12.2 (or Windows 98 SE, XP, or 7).  The drive is seen 
during Linux boot, but it cannot be mounted.
    The drive originally was formatted as NTFS.  I formatted it as ext2 
and was able to mount it.  I then formatted it as NTFS (using mkfs -t 
ntfs), and that's when the fun (or trouble) began.  I wrote Seagate a 
week ago, but they have not replied.  Their web  site  says they do not 
support Linux.
    Anybody have any thoughts as to how I can revive this paperweight?

Thanks, and regards....Zeb
