I recently bought a 661-2048 floppy drive for my PDQ G3 PowerBook. I read everywhere on the internet that the PDQ floppy was the last SuperDrive one in a laptop, so I was very surprised to discover that my unit (marked 821-4156-A) doesn't read DD 800k floppies, not even through DiskCopy. I noticed there are 2 different versions of the floppy drive for PDQ G3: 821-4156-A and 825-4267-A. I own the first, which one do you have? Did you successfully manage to access 800k disks. Thanks in advance!

I honestly admit this is my first time using SCSI and I still have to understand what “term power” is. I mean, I got how it is supposed to work but I don’t really know how I should check for it either on the PowerBook or on the drive itself.

I also tried any selectable ID on the device with and without the Apple terminator without luck, the only difference I was noticing was the used IDs shown in SCSI Tools.

Hello, I've been trying to read some SyQuest 44 MB HFS formatted disks through a SyQuest SQ555 drive. I'm connecting it to a PDQ PowerBook G3 with Mac OS 9.2.2. I've connected it via SCSI through a HDI-30 to DB-25 adapter and a new DB-25 to 50 pin centronics cable. The device is correctly terminated and I selected SCSI ID 4 on it. Here are some photos of the setup: https://imgur.com/a/kSKLTTE The thing is that SCSI Tools from 1987 shows that SCSI id 4 is currently connected, but any other tool only shows up the motherboard on SCSI id 7 Here are some pics fro
