The problem suddenly appeared just once after months without a problem.
It was qmail-send that couldn't create a file on disk.
It happened at a very quite time (at night, no backup or whatso-ever was running), and after qmail-restart everything was fine again.
I'm trying with the maintainer of the package to solve the problem, and he asked me to mount the qmail-queue synchronous.
That's when I bumped to this MBR-problem
@bormant:
EFI was tried but failed to install with the slackware USB-stick, so it was skipped and tried with normal install.
@syg00:
I think your right (EFI header is left behind).
Code:
~# sudo dd if=/dev/sdb count=1 skip=1 | strings
EFI PART
��B%
1+0 records in
1+0 records out
pC��բ���
512 bytes (512 B) copied, 9.9175e-05 s, 5.2 MB/s
Should I clear this, as said on:
http://www.rodsbooks.com/gdisk/wipegpt.html
And what about the first cylinders?
parted says it's first partition is 105 MB boot,
fdisk doesn't see that, it's first partition starts at cylinder 2048
Also note that parted says: "Partition Table: gpt"
For the records my outputs of sda (both sda/sdb have this "problem")
Code:
~# gdisk /dev/sdb
GPT fdisk (gdisk) version 0.8.7
Partition table scan:
MBR: MBR only
BSD: not present
APM: not present
GPT: present
Found valid MBR and GPT. Which do you want to use?
1 - MBR
2 - GPT
3 - Create blank GPT
Code:

Warning: /dev/sdb contains GPT signatures, indicating that it has a GPT table. However, it does not have a valid fake msdos partition table,
as it should. Perhaps it was corrupted -- possibly by a program that doesn't understand GPT partition tables. Or perhaps you deleted the GPT
table, and are now using an msdos partition table. Is this a GPT partition table?
Yes/No?
