--- Comment #3 from Tomasz "CeDeROM" CEDRO <to...@cedro.info> --- Hello Andrew! :-) Thank you for your reply. There is a discussion on a mailing lists (questions andusb), where some folks say this is the pendrive problem, others suggest that invalid MBR may be the reason of discarding writes to MBR. I think here is the best place to ask questions and solve the issue directly with authors :-) 1. I would like to clarify why I was unable to write to MBR (first 512 bytes) of the da1 while there was no problem with writhing to the rest of the disk? 2. GEOM_PART: integrity check failed (da1, MBR) <- could that block / discard writes to MBR silently? 3. Why `dd if=/dev/da0 of=/dev/da1` did copy all disk except the MBR? 4. Why I was unable to write to MBR from a file but it was possible to write that data from a file over md0? This is the first time such situation happened to me in FreeBSD for many many years. I am working a lot on disk copies / images so reliable and trustworthy DD is a must have for me.. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-geom@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-geom To unsubscribe, send any mail to "freebsd-geom-unsubscr...@freebsd.org"
