Not sure if it is related to the update this morning but last week, things worked fine. Booting with previous kernel version does not help.
Any suggestions?
Many thanks in advance.

kdvgent,
The whole drive is there. /dev/sdb extsts but the partitions are missing.
Do you have the MSDOS partition table code in your kernel?
If its missing, the kernel can't read your partition table.
The option for GPT is separate, so that will still work.
