Synopsis: fdisk: Unable to read MBR: 5TB drive.
Environment:
System : OpenBSD 5.8
Details : OpenBSD 5.8-beta (GENERIC.MP) #1125: Fri Jul 3
20:54:45 MDT 2015
[email protected]:
/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
Description:
Unable to (fdisk -e or fdisk -i) usb3 5TB drive with 4096-byte Sectors.
The usb host port version usb2 or usb3 makes no difference.
Smaller 500GB 1TB 2TB and 3TB drives work as expected,all show
512-byte Sectors.
Using ( disklabel -v -A sd0 ) does aper to allocate partitions.
Also not able to ( dd if=/dev/zero of=/dev/rsd0c ).
Although ( dd if=/dev/zero of=/dev/sd0c ) works as expected.
How-To-Repeat:
# fdisk sd0
