errors in the boot procedure badCRC
 

hi,
i m an absolute novice so help me out
i had installed red hat 9 a month back on my p3 550mhz pc.it worked fine
for a month,i used the text mode only(dint have enuf RAM,64sd)

i had windows ME installed on my single samsung 10gb drive
before i installed linux.
GRUB was my bootloader and it was installed in the MBR.
so the other day i tried to boot in to red hat and during the boot procedure
i got the following error messages
hda: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hda: dma_intr: error=0x84 { DriveStatusError BadCRC }
hda: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hda: dma_intr: error=0x84 { DriveStatusError BadCRC }
hda: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hda: dma_intr: error=0x84 { DriveStatusError BadCRC }
hda: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hda: dma_intr: error=0x84 { DriveStatusError BadCRC }

and somethings after that i dint note
it failed to boot up after these errors.
i tried booting linux again but the same things happened.
later i tried booting into windows,it did with some errors.
the second or third it failed to boot up and asked me run setup again.

so i formatted my c:/ drive and reinstalled windows which is working properly
i think i might have wiped out the mbr in the process as grub does
not appear on booting.

i guess i still have linux installed but i need a way to access it,and fix anything
i checked out the errors in some of the forunms but i dint understand much

one more thing i dint mention was i opened up the cabinet just before these errors
started.i had to take out a floopy drive that had stopped workinhg a long time back.
before i formatted and all,i did make sure no connection relating to the hard disk had come off.
dont know if that had anything to do with it.

help me out,i want to access linux without reinstalling it.
and also i dont want to cause permanent damage to the hard disk
and what causes this badcrc thing anyway?

thanks
dj

Each disk sector has a CRC (Cyclic Redundancy Check) information. When the sector is read there is a check
if the submitted CRC is equal to the CRC calculated from the received data. If not, then there is something wrong with
that particular sector *or* in the transmission.

Bad CRC means either the file(s) being read are corrupted
A sector on the drive got corrupted, e,g, due to a disk head crash.
Transmisson problems.

So you probably messed up some sectors on the disk drive.

Boot from the installation CD. There will be an option like "rescue".

Then you can reinstall GRUB.

err,problems
 

thanks a lot vlad for helping and all..
was on your advice but i reaized the insstallation cd i had burnt does not seem bootable...the cd i installed from did infact boot,i guess the images part of my back up cd are not in the first few sectors or something...will do something bout that....
