I'd agree with you about the high number of PCCs. The HDR-T2 here is set to come on at 5pm and off at midnight so the figures are 13625/3701 POH/PCCShould be fixable with fixdisk.
Worrying though with such low hours. But high number of stop/starts relative... - I still maintain it's better to leave it on, overall.
I don't agree. The differential thermal expansion and contraction as the result of power on/off cycles will promote failure due to stress fractures in circuit tracks, solder joints (especially lead-free), IC internal bond wires, etc etc. This is the usual cause of failure in any electronics assembly if you analyse the detail of the failure down to sub-component level, and anything which reduces these stresses will improve the service life.The life vs cycles idea is another one that goes back to the very early machines and has been largely disproved nowadays, or at least modern discs are built to cope easily with cycling.
Me neither.I don't agree.
Likewise.My HDRs are on 24/7.
But those percentages are irrelevant without considering the bad sectors.If you look at the life left column in the table in the OP you can see that the tool estimates 90% on hours but 94% on cycles (ours has 91 & 94), so presumably the disc manufacturer doesn't see that many PCC as being a problem.
