ok, i anybody know why i got data error, coz im trying to avoid that in the future, right now currently i'm using stellar-phoenix data recovery, its working but it takes long time to scan the whole hard drive aprox takes 12 hours to scan 10% of the hard drive ( 160gb), any suggestion what is the best data recovery program? do i using the right program?
try GetDataBack, if this program is giving you trouble.
put the D drive in the fridge overnight.  Boot with C, and very quickly try to copy as much stuff as you can.  Start with the most important directories first, like D:\my documents.  You only have 5-10 mins before you will get sector errors.  If you get them immediately, you can write off most data on that drive.
Important comment on scrathcyboy's post.

Place the hard drive in a SEALED plastic bag before placing in fridge.

Once removed, leave the hard drive in bag, but connect the cables and seal the bag as best as possbile (rubber band, loose string - this is to prevent condensation).

This is a last shot attempt, it usually only works once.

Other posters have recommended GetDataBack, I do too.

hi thx for all the inputs. really2 usefull, yeah i'm still on recovering process, it takes while prob 2 days, but i think i only manage to safe 50% of the data, since when i tried to open some files and it's corrupted.... (with stellar-phoenix), right now im trying getdataback hopefully it's not corrupted as much as the last one..
anyway is there anyway to fix the corrupted program or do i have to use a particullar setting on the program to get the maximum result? thank you very much
If the drive gets bad you get that error too. Once you have recovered the data (I agree that getdataback is the best, butthat will take a long time too) you should really extensivly test the HD. Best is to use the utility from the manufacturer, but maxtor's powermax will work with most HD's I know. Most of these tools, if you don't want to download them individually from their homepage, are on the UBCD

Forgot to mention, if you get errors with these tools, you should replace the bed disks. Maybe you can get a warranty replacement.
