Maintaining Trouble

The hard drive in RFO2 has given us trouble before. A year ago, we swapped out the disk, the enclosure, and even the computer itself. For a while, it was smooth sailing, but then started acting up again.

So, after replacing the disk and enclosure again, we tried the power and data cables. That was an improvement, but still not 100%. And since we can’t observe without the hard drive, anything less than perfect isn’t good enough.

We’ll be headed up to Ferguson again soon, this time with a new idea in hand, to try to put this trouble maker to bed once and for all: a solid state disk. Smaller capacity, but completely different performance, electrical, and other characteristics.

Since RFO2 wants to be an attention-hogging snowflake, here’s the work from its perspective. LaserSITTIE is, by far, my favorite piece of maintenance equipment. There’s nothing like sitting when we previously had to bend over the instrument, or kneeling on it instead of the often-sweltering roof.
