I think that's the ribbon that connects the spindle to the PCB ?
Why did you unplug it ? Did you unplug it with the drive turned off ?If you have disconnect it with the power off and then connect it again it should pose no problem. The only problem that i see is that if you remove that ribbon with the drive working ....
Are you sure the drive is spinning and that the ribbon is hold in place properly ?

As for the table it would help to have a picture but i can guarantee that it won't help you at all to fix your problem.
Is the drive detected on the bios ? Is the drive spinning ?

Exactly
My mean is the ribbon that you talking about it
Now i have to give more details:
Two hole of the IDE cables is blocks. I plug my IDE cable inverse and 2 block holes push two pins off HDD into the HDD. But still Bios detect HDD and i could boot windows and access data. so at that time there is no problem. any way i want to be sure. So i open the PCB, unplug the ribbon and push back the two pins of IDE port. then i give back the PCB on HDD and plug again the ribbon. then goto bios and see my HDD still detect. but my windows not booting. i used a maxtor HDD on my pc for boot the windows, now i have two hard disk on my pc. when i want to access my data i understand all my hitachi partition is deleted and i have to re create partitions. the hitachi is no problem and i can create new partition and use it again, but i need my data
im expert, many times i have many problems, i could resolve them, but i have not any idea about this one
realy thanks for your reply

the hitachi is no problem and i can create new partition and use it again,

And why do you want to re-use a cheap hitachi drive with

two pins off HDD into the HDD

??? Do yourself a favour and go buy a new HDD ! Then you can clone the damaged drive on the new one with something free called partition saving and when the copy is done you can run another free tool called testdisk and re-create the partitions on the new drive !

I purchased a new Seagate 1 TeraByte HDD:
