Upgraded and lost my data drives

[tim_m]

I upgraded my Ubuntu install and the system boots except it ignores my two data drives. I get a prompt to continue waiting, skip or manually recover. If I skip I boot into Ubuntu. The fstab entries for the data drives are:
/dev/hdb1       /itunes            ext3 noatime 0 2
/dev/md0        /musicorig      ext3 defaults 1 2

I booted with a knoppix cd and both drives are found and contain data. What steps can I take to remount these drives and recover the data?

Thanks.
