NTFS partition lost :/

[koschka]

Hello,

I've tested jkD on my laptop, it works fine.
But, when i've tried on my desktop (W2k sp4), I had some error box during the step 5 (has i could remeber). T
he first message box said "can't read file XXXX", after clicking "ok", an other error message "can't read file YYYY".
I've decided to stop jkdefrag and after tried to access my disk... ooops, can't read drive D: (D like datas :/)
Even after rebooting it's the same. I can't read any datas on this ntfs drive.

Does anyone have an idea to rescue my drive ? (and sorry for my poor english)

Hi,

this sounds like you have a major hardware problem. I've seen this a couple of times over the last years during my work. Now probably your MFT and/or partition table has gone corrupt.
Is your drive still visible in the bios and in the windows disk manager?
If yes and if you are lucky you will be able to save your data to another drive with some of the recovery tools available on the market. But none of them is for free as far as I know. At least some of them are doing a really good work and helped me and my company a couple of times to recover the data.
If not you will need a recovery specialist and their will bill you a fortune without a guarantee that they will be able to recover all your data.
I hope you did make frequent backups of your data.

best regards
Guido

I'm very sorry to hear that you have lost your harddisk while using JkDefrag. You are the first, or at least the first that I have heard of. I am therefore certain that the problem was not caused by a bug in JkDefrag. The program excersizes harddisks in a tremendous way, and can easily trigger a hardware fault. But that's not much consolation to you...

Take a look at http://www.ultimatebootcd.com/. It's a free CD with a huge number of repair tools, including lot's of harddisk tools. I don't know how much of an expert you are, some of the tools are very dangerous and must be used with extreme caution. Try the non-destructive tools first, such as the tools to try and read the disk and backup everything, before trying to repair it. Best of luck, and I hope you'll be able to get (the data on) your harddisk back!

If the desktop disk was larger than ~137 disk-GB (i.e. 128GiB) and you had not enabled "big LBA" (48-bit addressing), I'm sorry to say your data is most likely lost (unless you really know NTFS' disk-layout, in case you can possibly fix it manually by writing tools to do it, but take it from one who has done it: it's painful, slow and quite complex, and if the MFT is wiped it's orders of magnitudes harder if at all feasible or even possible).

For more information about this issue, do a web-search for EnableBigLba.

Try using File Scavenger to recover your files. It's very efficient, even for damaged HDD and when partitions are lost !
