[Apologies for reposting this --- 1st attempt messed up] Hi, hardware people. I need some info about the 360k floppy drives in my Z-158. The B: drive is flaky, and I wanted to swap A: with B: to make sure that it is the drive that's at fault (rather than the controller or something). I believe that there are jumpers on them to indicate which is A: and which is B: but the jumpers are unmarked, and quite different between the two. General information about jumpers for A:/B: would help a lot. I could also use specific data about the drives... One is a Panasonic/Matsushita, with the numbers "JU-455-5 ACG", "FMD00790B4", and "JVC SS01FF" on it. The other is a Magnetic Peripherals/Control Data drive, "ID 9428", "PN 77740012", "LOT H-8519". The machine came with one drive and the other was added later --- I think the Control Data drive was the original one, although it's the B: drive now. Any info would be appreciated. Oh, for what it's worth, the drive problem is that it has *much* trouble reading sectors on the innermost tracks. Lots of "bad sector" errors when I format a disk, although the same disk will format fine in the A: drive. (Following up on a previous posting of mine, it appears that I can drop in a 3.5" 720k drive with no problems...)
