Partitions have vanished!
i woke up this morning to find that all the logical partitions on my second hard drive have vanished! fdisk -l for this drive now turns up:
However, prior to shutting down last night hdb4 didn't exist and hdb3 was an extended partition containing hdb5-9 (and several distros!). Thankfully there was nothing particularly important on any of the partitions but what's happened!?
Disk /dev/hdb: 163.9 GB, 163928604672 bytes
255 heads, 63 sectors/track, 19929 cylinders

/dev/hdb4 19929 19929 8032+ e W95 FAT16 (LBA)
Is there any way to recover the data?
