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, 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.

sorry. but please close question by choosing answer (or the answers -- use split points link for that just above where you reply) that helped you the most. thanks.

Since there is no solution for my problem. So I split the point among participants to say thank for your attempt....

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.
