Hello,
I recently had a Toshiba
You hit the correct jumpers for this model to remove the motherboard bios lock, which shows you have done your homework well. Toshiba, like Dell set a bios lock and HDD lock on some laptops for security reasons, often when the cmos battery needs changing, it manifests itself.
As to why you got this request for a bios pass is very odd, if you did not change the cmos battery, however, removing the battery as you state would not fix the hard drive problem. The hard drive will remain locked and if, as I suspect, it is a security measure, you will not be able to remove it and externally access files or even format it by slaving it in another computer or docking station.
Your best solution would be to contact a Toshiba service centre and explain the problem and ask them for a bios unlock code. IF this was installed at the factory, they should be able to remove it (you WILL be asked to provide proof of ownership)
I have heard of some laptops being "time locked", which is where the time/ date settings in the bios trigger a request for a bios password for security purposes, but never actually seen this occur. This might explain why the bios pass request appeared randomly as it did. There is the possibility that this was caused by a virus, although, again, I've never heard of this happening.
