5.25 floppy drive

Hi I have an old Pent 1 Dell 120T I popped a oldish 5.25 floppy drive into it.
It’s a 1.2MB unit but the PC can’t Format the DD Floppy Disks. Is it possible the PC is not suited or two young or old. The Bios dose have the settings for it as well as the 750K.

Forgot to mention running DOS 6.2 Win 3.11

if the disks can be read then i would think its some form of disk protection, on a 3½" floppy you move the plastic tab on the back, but im not sure about 5½" drives. there has to be something similar to prevent overwriting the disk.

or it might be that the protection is a break out tab (like the video cassette), which you need to cover with a bit of selotape or something similar.

I don't recall ever having any sort of write protection on the 5.25 floppy. If the floppies are scratch diskette ie fresh out of the box then they should format with Format A: for a hard disk system or Format B: for a dual-diskette system.

Wasn't it a stick on silver tab or something?

can vaguely remember them at work in the early 1990's

Almost, Fellsider

"sticky paper tabs are folded over the notch in the side of a 5¼-inch disk to prevent the computer from writing data to the disk"

You've got to cover up a little square notch on one side of the disk if I remember correctly.
