Best way to transfer files from OpenBSD to Windows 7?

[guitarscn]

I have about 50GB worth of files to move, a couple files which are like 5GB in size so I don't think FAT32 would work.

In any case, I have an external hard drive with 2 partitions I already pre-formatted:

#fdisk
Disk: sd1       geometry: 12161/255/63 [195371568 Sectors]
Offset: 0       Signature: 0xAA55
            Starting         Ending         LBA Info:
 #: id      C   H   S -      C   H   S [       start:        size ]
-------------------------------------------------------------------------------
 0: 83      0  32  33 -  12033 171  42 [        2048:   193318912 ] Linux files*
 1: 0B  12033 171  43 -  12161  72   7 [   193320960:     2050048 ] Win95 FAT-32
 2: 00      0   0   0 -      0   0   0 [           0:           0 ] unused      
 3: 00      0   0   0 -      0   0   0 [           0:           0 ] unused

Here is my dmesg:

# dmesg
[snipped]
sd1 detached
scsibus2 detached
umass1 detached
umass1 at uhub0 port 1 configuration 1 interface 0 "Seagate USB Mass Storage" rev 2.00/0.02 addr 3
umass1: using SCSI over Bulk-Only
scsibus2 at umass1: 2 targets, initiator 0
sd1 at scsibus2 targ 1 lun 0: <ST910021, A, 0000> SCSI0 0/direct fixed
sd1: 95396MB, 512 bytes/sec, 195371568 sec total

It just repeats this over and over every time I unplug/plug in my external hard drive.

On the FAT32 drive, I created a test text file, but I can't seem to mount /dev/sd1i:

# mount_msdos /dev/sd1i /mnt/mount1/
mount_msdos: /dev/sd1i on /mnt/mount1/: Device not configured

I can't seem to find the ext3 partition, either. I tried mounting mount_ext2fs /dev/sd1a, sd1b, etc. all the way up to like half the alphabet.

I thought I could put the larger files into ext3, use an ext3 reader on Windows 7, and copy over the files that way. The FAT32 I was just gonna use for the smaller files (like the Firefox executable installer and such).

Does anyone have any other ideas? I have like 2 more external drives
