Accidentally set wrong Jumper and lost its data

Hi all,
I had Maxtor 6L 160PO (160 GB) as a data storage hard drive for about 3 month in a windows 2003 OS Pc, Yestersday I unpluged that hard drive and connected to another Pc that has windows XP as an OS, in the process of plug this hard drive to the other machine I did accidentally set CLJ jumper on instead to set it as Slave  or  CS (cable select) after I turn on the machine it does not shown this newly connected hard drive, so I realised that I accidentally set the wrong jumber .

Since then the hard drive can not be read even that I plug back to the original machine with a correct jumper setting, of course.
The BIOS reported the size of the hard drive is only 128 GB and in Windows 2003 OS  Computer management- Disk management reported that the size of the hard drive is only 31 GB, even worst the hard drive is reported to be unformatted. Every time I click on the drive from Window explore I will get a prompt to give me option to format this drive.

If any one know how to retrieve the data from this disastor, Please help.

Many thanks.

nctran.

Windows XP should not have done that, it does not make sense.  What makes more sense is that the motherboard did not recognize the full capacity of this drive, so you used some MAXTOR drive utility to put a sector translation program on the boot sector of the hard drive -- thus this maxtor utility showed to full capacity of the drive.  When you inserted it in the XP system, windows overwrote the device media byte with its own signature, so now the maxtor utility is not running any more from the hard drive.

I would trace your steps to the beginning and find out if you ran any Maxtor software on this hard disk to make the OS "SEE" the larger drive (given the MB limitations).  If you did that, then you should be able to run that same program again, from a floppy or CD, and once again see the full contents of the drive.

BTW Rindi, getdataback will only work to recover if the BIOS sees the drive to full capacity, and that seems not to be the case here.  Therefore he really has "LOST" all the extended data unless the maxtor utility is reinstalled on the sector 0 of the drive, to make the OSes see the full size.  It is sector-LBA magic.

Make sure you have enough space on your server or elsewhere to be able to take the data that is on that drive, then get and run getdataback, it should scan the disk and show you what is recoverable. If you are satisfied you can buy the software and then you will be able to copy the data from this disk to that other free space. Once you have recovered your data, you can use the maxtor utilities to reinitialize the disk (lowlevel format or zero-fill).

Sounds good to me rindi

Alternatively you could try one of the freeware tools such as  PC Inspector File Recovery instead of getdataback:

Thanks guys,

Thank you for your effort, Scathcyboy is correct about the drive full capacity is not recognised therefore any recovery software out there that I know do not work.

  I initially intall that hard drive into the Machine which has 2003 server as the OS, I did not have to run any software to recognise its size, The BIOS has no problem recognise it as well as the OS. This problem only occurs affter I have accidentally set  the CLJ as described above. ( I suspect that when you set this Jumper on It will some how automatically create an partition of size 32 GB)

 There must be some utilities out there to view(to see what going on) or to fix the actually image of the disk so the OS can access data again.

I am very appreciated for your ideas and suggestion.

Thanks heap.

NCTran, look at the jumpers again at the back carefully.  There is such a jumper called a 32GB CLIP, it is possible you have the jumpers set to clip at 32GB maximum, which would cause this problem.  Usually the jumpers are both vertical, none horizontal (which is the 32GB clip).  Check this to make sure.  Maybe you read the diagram back to front or upside down, it is very easy to do !!!

Two other possibilities, the BIOS is not seeing it right if you have another drive on same controller.  Put it as the ONLY drive on secondary, jumper to master.  Reboot 2003 system, see if BIOS finds it.  Second possibility, the drive in windows is fixed at wrong detect.  You would have to boot into safe mode, and go into device manager (my computer, properties, hardware tab, device manager), then in the hard disk drives section, remove everything that is there.  Then also go into computer management, disk management, see if drive is seen.  If so, assign it a different drive letter than what it has.  Reboot in normal mode, see what happens....

Thanks again Scrathcyboy,

I tried all the posible things that I could thinks of, Including all your suggestions above. I even put the hard drive into different PCs. The BIOs can see the hard drive with full capacity but in the OS ( XP and win2000) can not see its data. everytime I click on the drive It give me an option to format the hard drive which I don't want to do to  lose my data.

For now, I think the only way to get the data back is to find any software that can read and fix the corrupted partition structure of this hard drive . Unfortunately, All the software that I know of don't do the job.

I guess, I will have lose a couple of days of works unless we can find such software.

Thanks,

ncTran.

I think you should look at getdataback -- www.runtime.org -- if the BIOS sees the drive correctly, then getdataback will see all the data.  This program is very safe, because it makes NO changes to the disk -- just gets the data off -- and even better, you dont pay for it until you know if can recover the data.

As long as the BIOS on whatever system you put this drive on sees it to full capacity, getdataback will work.  It sounds like the NTFS file structure has become corrupted....

Thanks Scrathcyboy,

I tried getdataback with the  XP pc but no luck.

Thanks for trying, I guess I have to format the hard drive and move on.

well, if the BIOS can see the drive correctly, the data is STILL there.

So before formatting, I would try 2 things.  Go to www.knoppix.com and download the knoppix boot disk.  This you cut to a CD.  It is a linux program, but it sees the REAL data structure of the hard drive.  See if you can find the data with that, if so, copy it off before formatting.

If that does not work, there are programs to see NTFS from a DOS boot disk.  There are some here --
http://www.google.com/search?num=30&q=NTFS+on+DOS

Now if you go to www.bootdisk.com or ultimate boot disk site  -- you can get a windows 98SE boot disk, with fdisk and format on it.  you can also add the free NTFS program on DOS to this disk, then boot to 98SE command prompt, and run the NTFS on DOS program, see if you can see the disk contents from there.  If so, you could xcopy (at least the data) to another drive on the system.

If the disk was FAT32 and not NTFS, you would be able to recover everything from this disk, no problems.

Thanks Scrathcyboy,

Again, I asked a friend to try it out your two suggestions  because I did not have a lot of time and turned out that we had no luck.

I spent quite a lots of time for a solution. Initially, I thought it is straigthforward to retrieve the data, Just a matter of getting the right software.

Unfortunately, I had to reformate the drive and move on..

Thanks,

Regards.
