The solution was much simpler than that. Win2k has an utility called
diskprobe. It allows you directly manipulate sectors. In fact in my case
information in first EBR about the next extended partition was overwritten.
It was matter of minutes to calculate the right data, write it and all the
chain of extended partitions was recovered. However I spent the whole
week-end learning about partitions in order to do this. BTW recover boot
sector in NTFS is even easier.
Actually I made floppy backup of all partitions tables as well as boot
sectors. Now I am looking for two DOS utilities from NT4 resource kit:
disksave and diskprobe.

No it just freezes for a fraction of second.

This is certainly HD head hitting something. But I have never heard that
kind of sound on other HD IBM or not.

The name of "one person" is Nicolas Rubinstein. As I remember he is no
longer on the list. He is otherwise smart guy and gave us many useful tips
about Win2k and overclocking. By the way I remind you that he fixed his
motherboard with a drop of glue.

I must admit that card in question fits rather tight and if your motherboard
is weak it can be damaged. But in my opinion his and mine problem is that we
tend to forget that most so called IT professionals are just incompetent
when are not trying to cheat you. It just hard to imagine that you paid $$
for a potentially dangerous misconceived card.
Finally, David about previous suggestion about FAT. From all that I had to
read about FAT/NTFS comparative stability I am happy to stay with NTFS. Most
if not all recovery utilities just take the address from MFT of the first
sector of file to recover and then recover the next sectors corresponding to
file size. Thus, unless you defragmented partition minutes before failure
your chances to recover are nil.
Theese are just my 2c,
Alexandre
