    Hello everyone,

    My father (who is getting better with computers) tried to defrag an external hard drive (USB 2.0), and he ran into errors that almost deleted all of his data (I'm getting this info from him...I don't know if he's stretching the truth). I know that you should run a disk check (scandisk/chkdsk) before you defrag your drive to correct errors, and when I told him that, he admitted that he neglected to do that, but I'll have to admit that I've never heard of defrag destroying any data. I defrag my external drives all the time and I haven't had any problems. I would assume that defrag would stop in the event of drive errors, but you know what they say about assumptions.

    Is there anything that I'm overlooking, or have I come across an incident that is new?

    Hi Nigelum not 100% sure but maybe it could happen if the data is corrupt a bit or theres damage sector on the usb 2 drive. I always do a checkdisk then defrag my drive.

    Defrag might destroy a little data if you pull the power, or crash your computer in the middle of it.

    might be able to recover it with some effort...
