In unix, disks are files like any other file.
So if your programming language allows you to
read and write files, it allows you to read and
write disks.
Just write the equivalent of:
int fd=open("/dev/hda",O_RDWR,0) ;
if(0<==fd){
check_errors(ls eek(fd,SECT_SIZ E*sect_num,SEEK _SET));
check_errors(re ad(fd,buffer,SE CT_SIZE));
modify(buffer);
check_errors(ls eek(fd,SECT_SIZ E*sect_num,SEEK _SET));
check_errors(wr ite(fd,buffer,S ECT_SIZE)); close(fd); }
and be sure to have the access rights on /dev/hda (and to know
what you're doing!).

Firstly, if you asked me advice on where to buy some goats-milk,
I'd answer in the context of where YOU stand now [especially
since you told me], NOT form where I'm standing.
For several reasons I need many partitions on my IDEs.
The one lost the chain of logical partitions at hdx26.
It's not linux, but that's not important.
The most convenient tool for ME [at my present status] to
read/write blocks is linux: dd; and to see/edit is linux:mc.
This involves a lot of tiring manual work.
I previously read of a contributor who automated the steps
of linux:fdisk [iterating through size guesses] inside of a bash
script, to recover his lost [last] partition.
I'm not keen on investing time to become more fluent in Bash,
which could drive dd.
I have other reasons to invest time in Python.
If Pyton could 'drive' dd, I would try it.
My normal OS is oberon S3, which can do better than the
C-code above, but I want to work at the highest level.
Understand ?
Thanks,
