Hello Shahar,

The block size could change after a medium change. The (untested) 
attached two patches cause a message to be logged in case of a block 
size change and also prevent attempts to parse the block size if the 
READ CAPACITY command has been aborted. It would be appreciated if 
anyone could review and/or test these patches.

Thanks,

Bart.
