However, some users are confronted with 'the media is write protected' in Windows 10. Help! The disk is write protected on Windows 10Ĭurrently, USB drives (flash drives or pen drives) and SD cards (micro SD or memory cards) are widely used by computer users to store and transfer data. I tried different floppys, but nothing change.How to remove disk write protection in Windows 10?

The Write Protect circuit seems ok even before doing this modification on a drive (if I try to format a protected floppy the format process whas stopped instantly while if i use a not protected floppy the heads move, like in the VIDEO 3 FORMAT) I also bypassed the Write Protect circuit of one drive (suspecting something regarding this) installing a socket for the 74LS125IC, disconnecting the pin 3 of the 74LS125IC from the socket and keeping the pin on the socket down to ground, but nothing change. Testing signals on the IWM all seems ok but when I'm trying to write an image using ADTPRO, with an oscilloscope I checked that the WRDATA PIN remain HIGH, while the WRREQ pin remain LOW (I supposed to see pulses on the WRDATA pin) and the floppy head remain fixed, so this is because the floppy is not formatted right? (See VIDEO 1 WRITE AN IMAGE) When i try to format a floppy, the head is moving to all surface, but at the end I get always 'Check disk or drive door' (See VIDEO 2 FORMAT) if i using ADTPRO, while using the DOS loaded using ADTPRO i get the I/O error instantly (the head do not move). I also tried to load DOS using ADTPRO and execute the command INIT HELLO, without no success. I can read, but not write or format floppy (by using ADTPRO).

Initially I suspected the problem was the drive, so I bought a new one but got the same behavior (Heads cleaned on each one). (To better understand the issue I attached 3 videos) Hi, I have a very strange problem with an Apple IIC.
