I have upgraded an SME 6.0 server to 7.0 (pre1).  The main HDD are SCSI on an Adeptec DTP raid controller.  I have two additional IDE drives mirrored using an Adaptec 1200 IDE raid controller.  This was removed for the upgrade as it has caused problems in the past.  I am now trying to remount the file system on this drive.  I am getting no success.
Fdisk reports the drive as being present (hde 60GB)
[root@linuxserver etc]# fdisk -l

[root@linuxserver etc]# 
Trying to mount it produces the following error 
[root@linuxserver etc]# mount -a
mount: /dev/hde1 already mounted or /home/e-smith/files/ibays   busy
[root@linuxserver etc]# fdisk -l
Snip from fstab
/dev/hde1               /home/e-smith/files/ibays  ext3 usrquota,grpquota 1 2
Now I tried creating a new temp mount point  but got the same error when tryinf to mount the device.
Where should I look from here I feel I must be missing something basic ?
