I have had a brick for an external hard drive with failing caps. I was
able to easily replace the caps and the PSU is back up and going.
Unfortunately, in this instance, the hard drive was an internal type. I
had just replaced a failing PSU due to bad caps so that may have
contributed to the hard drives demise. Of well. I need to pay better
attention to where I store my backups. They do no good if stored on the
same physical drive as the source.
Thanks,
James
