Hello all, long time lurker but finally came across an issue that I need to reach out for help with.
The Problem: I'm working on a Thinkpad 755CS I received from a friend who bought it at a resale shop in 1998. I've gotten it to turn on but it's in a state where I am unable to get any files onto it or off of it due to the floppy drive not working in Windows. The internal floppy drive can boot when the internal hard drive is removed, but once I add the hard drive, I am unable to boot from the floppy drive. I can boot windows from the hard drive but then windows errors-out when trying to read floppies. Same thing when restarting into ms-dos mode and trying to read the floppy from there.
I have cleaned the floppy drive a lot, although I already know it works since it boots a bootable floppy just fine.
I saw that windows thought there was a CD-ROM drive which was disconnected, which leads me to believe that could possibly be from the computer resale store using an external CD drive to reinstall windows in 1998. I removed that from the device manager.
I have tried a formatted 1.44mb floppy and a 720kb floppy (several of each actually). The error starts by windows saying the disk in drive A is not formatted and asks if I wish to format, I select a full format and it seems to try to re-read the first sector over and over before erroring-out with "Windows could not format the disk". This thing really liked to mess up the formatting on the disks when it attempts to load and format them, so it seems like it starts doing something but then halts.
I don't see any IRQ conflicts in the device manager, but it's really time consuming to flip between each device. I happen to have an HP laserjet printer. would a good troubleshooting step be to bring the printer home and tell it to print out a system summary to the printer? I see that is an option but never actually did that before.
Anything else to recommend for troubleshooting?
I decided against sharing any pictures right now since it's all very basic error messages.
