Beso,

the block size in the filesystem is 4k, this I know having formatted a
second HD with same sized partition as failed HD.

I don't know how much data I should tell dd to skip (and NULL=fill) in
case of read error. From the dd output I only know there is a read error
and only 32kbyte were transferred, but I have no idea how big was the
block of data dd was trying to access.

But probably, as Duncan suggests, this is not important. dd will try to
access a block size as specified on the command line, and if error
occurs it will zero-fill and jump to next block of data, but this size
it totally unrelated with the _filesystem_ block size.
