I'm currently writing (yet another) program to recover damaged disks, but
I have one big problem:
What is the maximum size of a partition under FFS ? Under the old file
system the root block has room for 26 pointers to bit map blocks, giving
26*127*32=105664 sectors or about 52.5 megabytes.
As far as I know, FFS does not such a limitation.
What exactly did change ? Are those bitmap blocks linked together somehow ?
If yes, how ?
Anyone ?
Thanks in advance,
Werner (g35@dhdurz1.BITNET)
