This morning after my walk I went to Fry's and found that the drives they have on sale were Seagate rather than the Maxtors they had piled up yesterday. Those were still $160, and had a 3-year warranty instead of Seagate's 5-year. Then I made the interesting discovery that the Maxtor's and some of the Seagates were made in Thailand, while the otherwise-identical Seagates in the big piles were made in China.
A quick trip home confirmed that the flaky Seagate drive I removed a couple of months ago was Chinese, and I seemed to recall that the failing one is, too. The Maxtor I've been using as the mirror drive is Thai. Drove back to Fry's and bought a Thai Seagate.
After that, we went to Dave and Joyce's to bring them lunch: barbecued chicken, cole slaw, and baked beans from Emil Villa's. Much appreciated; Joyce isn't especially mobile due to health problems (which, however, should be fixed fairly soon). From there we went to Kathy Mar's bash. Good stone soup.
I did a little singing at Kathy's: "Ship of Stone", "Cicero in the 21st Century", "Desolation -- Oh, No!", and "Lily, Rosemary, and the Jack of Hearts". I'm impressed with how much nose-watering has helped my voice: singing is less painful and doesn't dry me out nearly as quickly as it used to.
