There have been a number of electrical disturbances in my area recently. They have been complete power failures, and low-voltage episodes, "brownouts", where the lights dim for a while and then come back up to normal intensity. I think this has caused some kind of accumulating damage to my system and I am looking for advice on how to respond.
I have a 6100/60 with A Sonnet 400Mhz G3, 256 Mb RAM, system 8.1. Most of my files have been kept on an external 8.5 Gb HD, an old full height Seagate Elite 9 housed in a generic SCSI box. The box has three of the 4-pin power connectors inside it, presumably because it could hole 3 1/3 height drives. The Elite 9 takes up the whole thing, though. I leave the drive and computer turned on just about all the time because it has been my experience that drives last forever, figuratively speaking, if they are not turned on and off much.
There have been a number of brief power fluctuations that have caused the external drive to shut down even as I sit here and type, but which have no effect on the 6100 itself. It has always come back on if I turn it off, wait 5 seconds, and turn it back on. Then, Friday I was working at the computer and the Elite 9 just powered down. After waiting a while for the Mac to sort things out, I was able to save the file I had open on the smaller internal HD. Then I got into the scsi box to check on the power supply. It was dead, making at most 1 volt across any combination of pins.
Worse, I tried connecting a power supply from another 1/2 height SCSI box to the Elite 9 drive, and it still wouldn't respond. I confirmed that the spare box supply was putting out 5 and 12 volts as it is supposed to.
2 questions:
1. Is the 6100 likely to croak soon becuase of the low voltage episodes?
2. Anyone know any trick to resurrect a drive which has failed after the power supply feeding it dies? This could turn into a an expensive problem for me becuase I have gotten too lackadaisical about data back-ups on the external drive.
