I cant tell you anything about Testdisk but that I I do want to know is what did chkdsk say while it was running what were the errors it was fixing?

My Maxtor OneTouch 300gb NTFS (WinXPPro) started acting up. I goofed and ran command prompt from XP and then chkdsk and chkdsk /f /v /r. Now xp doesn’t recognize the NTFS partition. Using testdisk as:
If the partition has been reformated to another filesystem (FAT32 formated as NTFS or vice-versa),
* run TestDisk,
* select the harddisk, the partition type
* choose Advanced
* select the partition
* choose Type,
* enter the value corresponding to the previous filesystem
* choose Boot
* choose RebuildBS
Results in a failure message: Can’t read NTFS MFT Mirror also other software gets me MFT error messages

Just want to give a big “THANK YOU!!” to DTI for making the Partition Recovery Tool and to Jacqui for writing this article. I was scared about what might happen so I was able to make a disk image before changing any settings but the tool worked like a charm and my data drive is back to normal.

Ouch, 1 to 2 days to do a physical sector scan?! You should have already put that drive in a drawer/unplugged it until you could get a spare to copy it to.
It normally takes about 1 hour to scan a hard drive. My 1TB drive might take a little more than that, but it should never take over 4 hours. For the next time, get a cheap UPS that gives you at least a few minutes for Windows to shutdown. Oh well… Since you only used the first 50GB, it should be easy enough to try making an image file on an older drive. This will let you go back in case of an accident while trying to fix it. Good luck!

This tool would have helped me do the math for my damaged boot record, but I figured it out myself. Thanks for the next time, though!

I used your Partition Repair Tool, firts step, to disclose the following info for my Slave (not bootable) Seagate ST380013A, with 80 GB capacity:
Boot: NO. SH: 128, SS: 0, SC: 128, FS Type: Unknown, EH: 128, ES: 0, EC: 128, Rel Sectors: 2147516416, Total Sectors: 2147516416

I have read your instructions about using WinHex and the MBR Template to determine the correct values.

Are you aware of MBR Wizard? Would it do the MBR repair any easier?

Would the procedures in this article “How to Replace a Partition on a Single Partition Drive” work on a 500gb My Book NTFS USB EXTERNAL DRIVE?

Windows went down. Upon recovering, chkdsk was initiated against this drive. 12 days later, it went into phase 2 of 5. 2 hours later a power outage took me out again. When power was restored and Windows came back up the drive was no longer available to Windows.

The drive suffered no apparent physical damage ( still sounds the same ) but is not available to the system. All indications are that the Partition and MFT areas are corrupted.

It is my guess that chkdsk was writing to the drive when the second outage took place and chkntfs was running instead and with the /R option set.

Your thoughts would be greatly appreciated.

Thanks
Gary

P.S. There is only about 50gb of this 500gb used on this drive. Hope this will help others as well.
