Use dd to make a USB flash drive warm/hot?


I was shown a long time ago how to make a USB drive real warm including hot (like it hurts to touch) using the dd command but I dont remember. It really serves no prupose other than to show off and yes, I know it will cause wear and tear faster on the drive.

You could also see read/write speeds with this I think.

Anyways, how do you do it?

Disk could get hot by it's internal rotations during read/write operations. And if you want to check speed, try dd:
Code:
~$ dd if=/path/to/input of=/path/to/output
Also check manual here.

I think it would be a dd command that sends random constant writes to the disk. I forget the exact command but it is similar to a mega wipe disk/secure delete operation.

I googled this and found a post by the OP on another forum:
http://www.neowin.net/forum/topic/11...entry595572360
Somebody pointed to a wiki here:
http://romanrm.ru/en/dd-benchmark
It shows how to make dd sync after every byte which, I would guess, would cause more concentrated writes onto the drive?
