kassender 2 is best tool for repair badsector reset smart and also u can edit capacity..
also extract data from full badsector drives...

The Kesender II is more of a tester/wiper. Yes, it can do data recovery, but I wouldn't suggest using it for that sole purpose.

If you can afford it and want to do data recovery, I'd suggest one of our data recovery products, like the Ninja-F (ATA/SATA) or the King Demi AS-F (ATA/SATA/SCSI). They are more configurable and the recovery will be much faster.

As far as the Kesender II goes, yes, it's a great tool (I might be a little bias though ). It's very popular with drive recyclers.
