I've got a Z80 CP/M system with two 5.25 in drives. A: is ss/dd, B: is ds/dd. I keep getting the error message Bdos error on B:R/O when trying to delete files, or copying using PIP, and with Wordstar. The canonical situation is having a write-protect tab on the disk: I don't. Does anyone have any idea what might be wrong? Whatever it is, it's intermittent. Any pointers as to where the problem may lie would be appreciated. TIA, dan davison davison@bnl.arpa davison@bnl.bitnet davison@sumex-aim.arpa ...decvax!philabs!sbcs!bnl!davison

Some CPM systems will assign a dick drive a R/O when the drive door is opened, as when changing disks (hence the intermittence). If this is the case, enter CTRL-C after changing disks. Paul
