Hey,I've always said you have a very unique issue. I don't recall seeing anyone else go through as many as you have!
The actual number of HRs that I have received as replacements is actually higher than 60. I think 60 is around the number that were activated. A lot came in pieces or just wouldn't power up. They went right back.
But other than fan and power supply, I see no reason for anything else to regularly break in these things anyway. I have a feeling the number one issue that DIRECTV has other than hard drives though is power supply's, and then maybe the fans.
I've also had HRs that wouldn't work with my remotes unless I stood a foot away from the HR. I had a couple that got into 771 loops and wouldn't do anything but search for signals. Meanwhile, 10 or 11 other HRs were working fine. I had a 24-500, I think it was my first one, that went completely bonkers. Damn thing would do whatever it wanted to whenever it wanted to. I had a new 21-200 that started smoking the first night it was activated. I could go on and on, but I think you get the idea.
Most of the HRs I activated had big HDD in or on them and I'm still using all the 2TB HDDs (except for one and I'm not positive it was bad) that were in/on them.
But yeah, everyone is different. I just don't see enough people asking about issues that are likely non hard drive but definitely DVR related to think that hard drives aren't the number one issue by far, after install issues. I think installs are probably the number one issue in general people have with DIRECTV systems.
I don't remember exactly when it happened, but there was a time when HDD complaints were rare, then it seemed as if everyone was blaming the HDDs for everything.
My main reasons for all the replacements were bad installs and HDMI incompatibility. But the replacements rarely worked correctly either. Most of my problems were from late '06 to the spring of '08. Since then, I've had few problems.
Factor in my lousy luck, I'm the kind of guy you want to see walk into a craps game with a big wad of money, and that accounts for most of the HRs. The upside is I've learned a lot about these beasts. More than I want to know...
