-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Firstly, hello list. This is my first post here and while I'm a long time Linux user, I'm a recent FreeBSD convert so please bear with me. Yesterday I installed an extra hard drive that used to be in a Windows 7 box. In sysinstall I ran fdisk then label to try to get the disk ready. The problem was that even though after I hit 'w' and it didn't give any errors, when I did a `ls /dev/ad*` it was still showing the old partitions, even after a reboot. I tried running fdisk manually and a few other things I found on Google but they all seemed to just be silently failing since they never showed an error but the changes never really went into effect. When I was first building out this box I had an issue partitioning the disks but the behavior was different in that it errored with messages about not being able to commit or write the changes to disk. That issue turned out to be with some GPTs on the drive which I was able to remove in Linux with parted. Anyway, I figured that there was a chance that this might be a GPT issue since this drive came form the same machine as the other. I couldn't remember what command I had run and didn't feel like pulling the drive into another machine so I just ran `dd if=/dev/zero of=/dev/ad12 bs=512` and let it run. That must have done the trick because I was then able to partition the disk in sysinstall and all is well. What I'm wondering is what really went on here? I'm not clear at all as to why FreeBSD (or some mechanism within this installation) isn't able to handle this. Or was this a GPT issue at all? I'd like to find out what was going on so that I don't chase my tail again on issues like this in the future. Thanks. -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.16 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQIcBAEBAgAGBQJM22Q5AAoJEB/pNtMYu8Pl8G4P/RyHfn03BxY0tSaii2J1a5gQ L7q7ZK9mrvpXCv/tGk+ieWwct01cgpf3SRoEbmjpnL4c//g54fChCdOylJDD7wpU LlxB4CsNMkV9JIT46zkw6ET6ERFYVC0sG+DxJr3JRCkRcTseQjNbNaKJuESMHsu3 OoYrjKjosz5juqkqS0Ty930KCcWRX5DYLsBH0QSHg7q+9ZNnFBuNIB0os4DyZ803 rmxg0bz4YDzTHFe7sJG1/uhN1gUGT3jGUuXUEKnKIrZQaUvdJe3xfNtq/mqHKiZG il45ljdxESt/Y9p7MyGle439YM/BtFt48+O9vcbd0Oljl+nwlFVHNPMKd91KOv/b WPd8y1wmO2X7tTUetDqjby3GlRjvpuPrzddfbpj87DqKdvJ3hqGtGRflrMeWLklg dAS5n3Q8x42vu/5CXlCWtNO2GQMYWTX7VPWmCzymzC60A3YM4UoY3GEF7PV/tChS etUVcSp3JhpepOjgVyY7SA+dO3sZhLAvulqhy/KX6E1ffkCoRMPYWdu9zYXk1F/i 6tEpEDdU7QAViCSbUnp7ZZrt/QcG5XbD0yOUy1M/bvfkGo3qd+TukTCJ8s0JDZ8x lPYF+p8pkzm9zfFeA1e90VqkkhNb/gDFzwg3grcO5hEse4OXlsXMmA5kfxjVKbFj mUO0LYyMmd0QW49J91ts =w5P4 -----END PGP SIGNATURE-----
