Fix corrupt NTFS partition?

[Guest throwitout]

I'm trying to fix what looks like a corrupt NTFS partition on a HP

Media center PC.

 

Initial symptoms were that the machine would show the POST screen,

then show a blinking cursor in the upper left and not boot, giving no

errors. F8 will not offer Safe-mode options. I believe the user may

have been improperly restarting the computer when this started.

 

Pressing F10 at boot will still bring up the HP recovery environment.

 

The PC will not boot into recovery console from a Windows CD because

it doesn't recognize a valid file system on c:

 

The Windows installation CD lists the HP Recovery partition as FAT32

as the second partition, but an "unknown" partition with the remaining

balance of the hard drive size. I did not touch the partitions from

here, I was just checking to see if they were still valid.

 

Booting the machine from the BartPE "Ultimate Boot CD 4 Windows", My

Computer lists Drive C: as "RAW File system" Free / used 0 bytes, and

it lists H: as a the valid HP_Recovery partition.

 

None of the scandisk tools on the CD will recognize the partition.

 

TestDisk:

http://www.cgsecurity.org/wiki/TestDisk

 

Will recognize the partition as "HPFS-NTFS" with the proper volume

name and recognized will recognize the recovery partition as "FAT32

LBA".

 

I tried running the "Repair MFT" and "Rebuild BS" options.

 

Currently it lists "Boot sector Status: OK" and "Backup boot sector

status: OK" "Sectors are identical"

 

When i select Repair MFT it quickly flashes the message "Failed to

open inode: Input/Output error."

Offers to "Fix MFT mirror" I select yes, it responds "MFT mirror

fixed"

 

Going to "repair BS" it says "Use MFT from 786432, confirm?" I select

yes

"

Sectors per cluster: 8

MFT LCN 786432

MFTMIRR LCN 16

Mft record size: 1024

 

filesystem size 470206422

MFT LCN 786432

MFTMIRR LCN 16

Mft record size: 1024

clusters_per_mft_record: -10 ???????

Clusters_per_index_record 1

Extrapolated boot sector and current boot sector are identical.

"

If I go into the list feature of TestDisk it will show me the correct

file structure of the partition, and of the couple files I tried using

the copy function on, they copied to the BartPE RAM drive correctly.

However the partition will still not appear to be valid in BartPE or

any other application, even after a reboot.

 

Is there any other free recovery tools that might let me fix this semi

corrupt NTFS partition?

I think your best bet is to format the partition and do a reinstall of the os.

Re: Fix corrupt NTFS partition?

 

It is worth using the hard drive manufacturer's test software before you

follow sgopus's good advice. You may as well check the drive.
