I had this 320GB 2.5" HDD in external USB casing for quite some time (2 years +) and it fell accidentally a week ago while connected to the system, and as a result got damaged. I do not have any data on it so data recovery is not an issue. I still want to use it to copy data from one PC to another, and so, would like to isolate the bad sectors. I have read other related posts and found it can be done by partitioning in such a way to isolate bad sectors. However, first problem is to find bad sectors. I'm using Windows 7 and Chkdsk with /R option won't identify the bad sectors unless data is already stored in those sectors (It just goes past empty/free sectors), and when I try to copy data to HDD, it gets stuck for a long long time when it encounters bad sectors, and I need a quicker way to identify bad sector locations. I remember there used to be such utilities for DOS (Noton Utilities, etc.). Can someone suggest a software which can scan the hard disk surface and mark bad sectors so that I can then repartition the hard disk?
The disk has no problem in connection and identification by OS, and trouble starts after 20-25 GB of data copying.
