Since you are technical, take the drive out of the case and attach it directly to your computer’s disk controller, using the appropriate IDE or SATA data and power cables.
You may also want to try mounting it on a Linux system, both as a USB device and, out of the box, as just another hard drive.
If the drive is truly dead, then get a BIG FAT MAGNET and bulk erase the drive before returning it. That should erase most if not all of your data. I believe there are even bulk erase machines that could do an even better job of it.
I could, but why? I have the drives redundant with RAID stiped, and the manufactured will just send me a new one. I’m not concerned about my data; it’s already protected. I’m just wondering about a big scary possible picture.
Can't be done unless you work at a scrap yard and attach it to a magnetic car hoist.
