<div dir="ltr"><div><div>I have a couple of 1TB external USB drive that I was using for backup, and replaced with an eSATA dock some time back.<br><br>I wanted to re-purpose the 1TB drives for use with the PVR.<br><br></div>
So before doing this, I wanted to check the disk for bad sectors.<br><br></div>The method I used is to connect the drive to the laptop, unmount the NTFS filesystem that is on it, and then do:<br><br>time dd if=/dev/sdb bs=16mb of=/dev/null<br clear="all">
<div><div><div><br></div><div>So, I am trying to read every sector off the raw block device, in 16MB chunks, if possible.<br><br>The problem is that it is taking many hours now, with the laptop heating up (73C to 81C).<br>
<br></div><div>Now the questions:<br><br></div><div>1. What is a reasonable temperature for a laptop on A/C power? Under load and no load?<br><br></div><div>2. Is there a better way for checking for errors on a disk? Faster way?<br>
