I have a Seagate st1480N disk, with sun roms: Vendor: SEAGATE Model: ST1480 SUN0424 Rev: 7516 Type: Direct-Access ANSI SCSI revision: 02 running fdisk on this disk fails because on exit nothing is apparently written (the disk led shows activity): reentering fdisk shows an invalid or the old disk label. I tried both automatic disk label, a custom disklabel with auto or correct (manufacturer's) values. No difference. I tried - attaching the step to anther computer running OpenBSD. There I could disklabel and format the disk w/o problems - rebooting after fdisk exited without errors - dd'ing the first sector to zero. This removed the OpenBSD label but still I couldn't create a new one finally, since I have another almost identical disk (same model, slightly older revision, not sun roms) I dd'd the first sector from that one to this disk. Now disklabel sees it. I formatted the disk and can use it flawlessy. I conclude so the problem is fdisk related since dd can access the first sector without problems. But I might be wrong. Reproducible: Always Steps to Reproduce: 1. 2. 3.
did you try modifying the partitions after creating the sun disklabel with fdisk? because it behaves the way you mention. just try erasing the swap partition or some other, re-create it and write.
well, you neglected to mention what version of util-linux you're using ... and you neglected to provide `emerge info` please re-open once you've done both of these things, and you've responded to Gustavo's question ... if his suggestion does not fix your issue, could you try with latest util-linux ? (meaning 2.12p)
-> we feedback
