Hi there,
Just a quick post as it is past bedtime here. Will post up tomorrow for you so keep logging back in to check.
OS: Winodws XP- SP2
HDD : 640GB SATA, (using it only for storing data, no windows installed)
System: Intel P4, 2.4 GHz, 1GB RAM (its a dell-optillex gx-270 machine)
I'm just a bit intrigued by this though,no windows installed? what does it mean?
Anyhow,how many partitions did you have on your drive, just two? one of which is now unallocated?
A quick scan at your post tells me you accidentally deleted your partition.
Will guide you through the steps to get your partition and data back, no need to lose any sleep, you should be OK.
Any info on what you were doing or what happened before your disk went offline? any info would be helpful.
cheers,HTH,

i've installed windows on another 40GB hdd. i was using this SATA hdd as a secondary hdd purely for storing data.
as for the partitions, i really don't remember how many, i had a few 50gb partitions and one 100gb partition.
as for what caused this, i recently bought a 1tb hdd(SATA), was copying data from this 640gb to the new hdd. the new hdd was having some issues, i changed the SATA cables and when i started the system, the disk went offline, tried changing the cables and it didn't worked, tried to activate the partition, didn't worked at all. Then used the testdisk and now am in stress.
All that i now see is one partition(50gb), the data of which i can't copy to another drive for some odd reason and 546GB unallocated space

if there is something else to be known, please do tell me so i can tell about it as well for recovering of data.
Regards
UPDATE:
just checked the 50gb partition and its NOT showing any files which were previously showing, maybe its because of the LONGgggggggg chkdsk which happened when i started the system?
