Disk is showing as locked that was previously fine

[3lectr1cPPC]

I’ve got my PowerBook 540c running on a 320MB IBM hard drive and it’s running the install still from when I got it. I went recently to put a 7.1 system folder onto it, switched to it in system picker and then when I went to boot it gave an incompatibility error. So I went to get an enabler for it and now upon booting from my external PiSCSI, it doesn’t let me write to the disk, it’s locked somehow and I don’t know how to fix it. Also really don’t want to wipe the drive if I can help it. I also can’t change the system folder back to 7.5.5 as it’s locked.

Can anyone here help?

I've discovered further strangeness. The disk before was being detected as a CD-ROM disk (for some reason???) which was probably why it was showing as locked. I removed the CD Sunrise driver that was detecting it and rebooted, now it doesn't mount. Gonna go run SCSI probe and probably norton or something to see what's up. I hope the drive isn't failing or anything like that.

Ok, solved. Told SCSI Probe to mount it and then, it did, and it's no longer showing as locked. That was weird.

Gonna blame SCSI voodoo and move on.
