Help! MBR or BootSector corrupt


X

xtoned

Hi!
Can someone help me with this? Yesterday I was using a data recovery
software, while Winamp is running, suddenly the machine turned off,
after that it won't boot.

My hard drive has some bad sectors and later I found out that the
RAM was also a little bit faulty, It was replaced. Later I booted the
machine with another HD, then the system(XP) detected the faulty drive,
But it didn't have partitions in it. Then I used Partition Magic 7.0,
It showed the disk, But It shows the whole drive as Unallocated and I
tried a data recovery software (a demo version of Handy Recovery), It
showed partitions and files as recoverable and then I tried Seagate's
SeaTools It stated Invalid MBR.

I think the problem is possibly a corrupt MBR or Partition table or
Bootsector and a little possibility of a boot sector virus. What can
Ido? There are alot of tools for restoring MBR's, But I haven't got a
Backup of it. I have Norton Antivirus 2003 and I have used Partition
Magic 8.0 in the faulty disk, I have used Partition Magic several times
to resize partitions. Does any of these or any other software store a
copy of MBR in the disk or registry. Because on a MBR access Norton AV
warns and I think it replaces it if needed and I think When Partition
Magic does tasks it replaces the MBR with a temporary one and when the
task is done it replaces the original one. Does Windows FDISK's fixmbr,
fixboot commands restores the previous MBR or just rewrites them.
What's the software that could help me? Please help me!

That is usually a hardware failure.

Which may well just indicate that the sector it occupys is flakey.

You dont necessarily need one if you know the partition structure,
particularly if there was just one partition for the entire drive.

Yes, some recovery software can handle bad a MBR
and some recovery software can recover some files
without the MBR being available.
or registry. Because on a MBR access Norton
AV warns and I think it replaces it if needed

Only if you have use NAV previously and its saved a copy of it.
and I think When Partition Magic does tasks it replaces the MBR with
a temporary one and when the task is done it replaces the original one.
Does Windows FDISK's fixmbr, fixboot commands restores the previous MBR
Nope.

or just rewrites them.
Yep.

Or a software failure.

Or just "Invalid".

Which is the same, basically.

The process is no different.
Yes, some recovery software can handle bad a MBR
and some recovery software can recover some files
without the MBR being available.

(What's the difference) (And no, that wasn't the question).

And some software just restores the MBR so you don't need any
additional (file)recovery software at all.
Only if you have use NAV previously and its saved a copy of it.


(Half)Wrong.


Yep.

Nope. It restores the code part. It leaves the partition table alone.
I'd try Easy Recovery Pro, but it aint free.

ResqDisk or FindPart + PTEdit.

Hi!
Thanks for the reply. Yes I've Easy Recovery Pro 6.0, Would it work? I
tried it but after some point I thought It wouldn't work and closed it.
Have you tried it? And where do you think Norton AV 2002 would store
the MBR?
Thanks!

Try it and see.

Yes. But not on your drive obviously.
And where do you think Norton AV 2002 would store the MBR?

Dunno, havent bothered to check. From memory
you get to specify that, and can put it on floppy etc.

Hah ha! NO need for combats guys.

Coz, Just now I fixed the system. I just inserted the Norton Sysworks
2004 cd, It had
an Autorun which allowed to run utililties without installing it. I ran
the Disk doctor, It
said There's an invalid partition table and asked whether it should fix
it by searching
the faulty disk for partitions, Then I rebooted and Right now Iam
posting this message
from the same system I had 3 days ago, still I haven't even installed
Norton Systemworks.
No matter what stuff from Norton are the best!

Some have found it screws the drive much worse than it was.

Is that why very, very few professionals use Norton products?

By professionals, do you mean those people that do things for money, that can be done for free?

So you need some plumbing / electrical work / car repairs / etc - can
all be done for free, Folkert. But you do it all yourself, right?

Try again, troll.

Why do people use companies like KEMA? Surely this sort of thing could
be done for free?

Where do you draw the line, Folkert?
