/dev/sdb. You don't fdisk a partition.

Could you please try? It now at least thinks I have a partition table Smilie. Check my previous post.
Well, my directions would've been on how to get that partition table back. That it has is both very good and very bad news; something's seriously wrong with either the drive or the USB cage for a sector to just vanish and return like that! Also good that you posted it here. Armed with that you have enough information to recreate it from scratch if it vanishes again.

If windows doesn't see the partition table, first off I would rewrite the same partition table back to it, just 'w' from fdisk /dev/sdb. If there's anything odd in it preventing windows from seeing the partitions, that may clear it.

NAME
repartition - load a partition table SYNOPSIS
repartition device [partition-file] DESCRIPTION
Repartition uploads a new partition table for the partitions of device. The table is obtained from the first sector of partition-file if given, device otherwise. Device may refer to the whole drive or a primary partition, depending on whether you want to upload a partition or a subpartition table. The partitions will be truncated to fit within the enclosing device like the disk driver does, unless the numbers are coming from partition-file. EXAMPLES
repartition /dev/hd0 repartition /dev/hd4 /etc/hd4.table Reload the partition table of drive 0 setting /dev/hd[1-4], and the subpartition table of /dev/hd4 setting /dev/hd4[a-d] using a file. The latter may be useful if you need more than the 4 subpartitions a single Minix partition gives you. DIAGNOSTICS
The new table is printed on standard output. FILES
/dev/hd[0-9] SEE ALSO
hd(4), part(8). BUGS
The disk must be in use for the changes to stick. The partition table of an idle disk will be reloaded on the first open. AUTHOR
