Invalid partition table Error

All hell came lose when i used Hiren's boot disk(or some other partition doctor software ) and so in its diagnostic that there is an error in MBR(but it worked well) so curious to see what happens i selected repair.............

And then i couldn't boot from HD gives Invalid partition table Error............

The thing is i had linux partitions in HD and this software has interpreted it as an error......

Two partition have been marked as active-----------------> this gives Invalid partition table Error



So what did I do


With xp boot disk booted in recovery mode............ :(  then did FIXMBR @ cmd prompt, but it didn't
 work.


Then used from Hiren's boot disk Norton partition doctor ----> diagnostic ------------>repair


And hey all boot errors solved...

no need to format the whole thing and lose all data and make it a mess.....

The state-run PowerGrid
Corporation of India proposes to lay down an under sea line between
India and Sri Lanka. The proposed undersea high voltage direct current
(HVDC) transmission line will be for the transfer of 500-mw, which will
be subsequently upgraded to 1,000 mw.

According to power ministry sources, “The
proposed undersea transmi-ssion line entails an invest-ment of around
Rs 1,500 crore. A pre-feasibility study is being carried out by the
PowerGrid Corporation for the proposed venture. So far undersea HVDC
transmission lines are in place between the UK and the France for
transmission of 2,000 mw.” PowerGrid Corporation’s plan was according
to the bilateral investment arrange-ment between India and Sri Lanka,
sources said.

The proposed undersea transmission line could be
useful for NTPC which plans to set up 500 mw imported coal-based power
project at Trincomalee in Sri Lanka. PowerGrid has installed inter
regional transmission capacity of 18,000 mw and plans to increase it to
37,000 mw by 2012.

PowerGrid has lined up an investment plan of Rs 55,000 crore for the same to be completed during the 11th Plan.

Earlier, power minister Sushilkumar Shinde asserted
that the infamous Enron chapter was closed and more and more investors
from abroad mainly from the US were keen to invest in the India’s power
sector.

Undersea power to Sri Lanka

Undersea power to Sri Lanka


Gestation period of forty two months


By Chandani Kirinde



The proposed India-Sri Lanka Electricity Grid Interconnection project
which aims to lay an undersea power line between Rameshwaran in South
India and Talaimannar could be commissioned within 42 months from the
inception of the work on the project, according to the pre-feasibility
report on it.


It has been
estimated that the project will cost around Rs 4.8 billion. The basis
for the cost estimates have been based on quotations from leading HVDC
(high voltage. direct current) equipment manufacturers in Sweden,
France and Germany.







The
pre-feasibility report is to be followed up by a full feasibility study
to be undertaken jointly by the two countries shortly, The Sunday Times
learns.


According to the pre
feasibility report, the proximity of the location of India and Sri
Lanka provides for the opportunity of power exchange between these two
countries through transmission interconnection.



The power supply position of India is envisaged to improve with the
commissioning of planned capacity additions, especially in the southern
region which is expected to have a large quantum of surplus supplies
between 2011 and 2012, reaching a peak surplus of around 6000 MW and an
off peak surplus of 12,300 MW.


The
interconnection of the southern grid with Sri Lanka shall help in
enlarging the power market reach for generation projects in India to
export power from India to Sri Lanka while Sri Lanka shall have access
to the competitive power availability in the Indian power market, the
Report said.


Sri Lanka, at present
is dominated by hydro power (50 per cent) but this hydro dominance
would reduce progressively in future as the future generations are
mainly thermal based. India on the other hand has a substantial amount
of hydro based generation (overall 26 per cent)



The Report said that the transfer of power from India to Sri Lanka
would also reduce the use of expensive thermal generation in Sri Lanka
based on liquid fuels.Thus the link will be mutuality beneficial to
both the countries with Sri Lanka achieving significant savings on cost
by importing cheaper power from India while India would benefit from
having access to newer market to sell surplus power.



The power supply scenario of both countries suggests that in the short
term period (2009-2010), India and Sri Lanka can exchange power to the
tune of about 500 MW. The quantum of power exchange can be enhanced to
about 1000 MW in the medium time period (2011-2012) when both the
countries would have reasonable experience in exchange of power as well
as a comfortable power supply scenario.



As of now, with the projected power scenario, it is envisaged to retain
the capacity of exchange of power of 1000 MW in the long term as well
(2015-2016). While planning the interconnection, flexibility need to be
provided so that either side can transfer power up to 1000 MW depending
upon the availability and demand for power, the Report said.



The transmission system between India and Sri Lankan need to be planned
judiciously as it would involve expensive submarine cables. The
transmission line would be 400 KV HVDC overhead lines from Madurai to
the Indian coast (near Rameshwaram (139 km), a 400 KV HVDC cable from
the Indian sea coast to the Sri Lankan sea coast (39 km), a 400 KV HVDC
overhead line from the Sri Lankan coast to Anuradhapura/Puttalam
(125km).



A detailed marine survey is to be carried out prior to the laying of
the undersea/submarine cables. The cable survey will look into the
traffic of movements of ships in the area, depth of sea, earthquake
zones and volcanic actives as well as the presence of sharks in that
area of sea.

$450-m submarine cable link to connect Madurai and Anuradhapura


New Delhi - The feasibility study for the proposed $450-million
mega undersea power transmission link between India and
Sri Lanka is slated to be ready shortly.

The 200-km submarine cable would enable India to export
electricity to the island nation and is likely to be set
up with a capacity to wheel around 1,000 MW of electricity,
government officials involved in the exercise said.

The report on the HVDC (high voltage direct current) link
between the two countries is being prepared by State-owned
transmission major Power Grid Corporation of India Ltd (PGCIL),
which had earlier estimated that it can set up the link
in around 40 months once all clearances are in place, officials
said.

The link is likely to connect Madurai in Tamil Nadu and
Anuradhapura in Sri Lanka’s North Central Province.

While a joint Steering Committee has been set up to oversee
the project, a task force comprising representatives of
the Power Ministry, Central Electricity Authority and PGCIL
on the Indian side and the Sri Lankan Energy Ministry and
Ceylon Electricity Board (CEB) on the other, has been firmed
up to study the feasibility report and make recommendations
to the Committee.

Officials said Indian utilities could get higher tariffs
from electricity supplies to the country. Initially, surplus
power would be transmitted from India to Sri Lanka using
the link.

With NTPC Ltd, already working on a 500-MW coal fired plant
in Trincomalee, wheeling power from Sri Lanka to India could
also be a possibility over the long term, they said.

Sri Lanka’s Cabinet of Ministers had, early last year,
given its go-ahead to its Energy Ministry on the project
and the United States Agency for International Development
is reportedly extending technical assistance to Sri Lanka.
Sri Lanka currently uses diesel — one of the most expensive
power generating resource — for nearly 65 per cent of its
power generation. The generation cost there is around Sri
Lankan Rupees 15 per unit (about Indian Rs 6.21 per unit),
according to CEB data. India currently has transmission
links with only Bhutan, as part of the 1,040 MW Tala hydroelectric
power evacuation system. The proposal to link-up countries
in the South Asian region is being seen as a forerunner
to the proposed BIMSTEC power transmission network, which
is under active consideration.
