You can download a bootable disk with gparted on it. * Perform actions with partitions such as: o create or delete o resize or move o check o label o set new UUID o copy and paste * Manipulate file systems such as: o btrfs o ext2 / ext3 / ext4 o fat16 / fat32 o hfs / hfs+ o linux-swap o lvm2 pv o nilfs2 o ntfs o reiserfs / reiser4 o ufs o xfs go to www.gparted.org to get more information. --doug
Re: Disk /dev/sdb doesn't contain a valid partition table
I once had an USB stick with a broken controller and couldn't partitioning it anymore. It was brand new, gets broken at the day when I used it the first time. It was warranted and I got another USB stick. Perhaps your drive isn't broken, but one cannot rule out the possibility that it's defect. I would test different USB slots and another, very short USB cable. Regards, Ralf -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

It looks like either the new partition you have been writing hasn't actually been written to the disk, or the kernel didn't realise that the partition table has changed. What do you mean reboot after creating partitions? This is an external hard drive that does not have any OS. So how can I reboot from it? Do you mean disconnect and reconnect? What I mean is reboot the computer (not boot from the new disk you're trying to partition, just reboot it normally). So: 1.) write the new partition table 2.) reboot the computer and run fdisk again and see if it still says the same If it still says the same, I'd try to connect the disk to an SATA port and try it again. If it still doesn't work, return it. Or don't go the lengths of connecting it to SATA and just return it ... 2) Is msdos a valid option to choose for this hard drive? Is msdos a useful partition type for you? Try Linux, and if it works, you can try to change it to msdos. There is no Linux option.

[1]: http://en.wikipedia.org/wiki/Partition_table [2]: http://en.wikipedia.org/wiki/Disk_partition There is confusion here between partition table type and partition type. The partition table holds information about the different partitions. An msdos partition *table* can hold a linux partition. Use msdos, gpt, or nothing: LVM over a physical volume, for a partition *table* type. gpt has the advantage over msdos (or just 'dos') that it supports partitions over 2TB in size. Use linux for partitition type if you don't go for LVM. Step one: INitialize the disk with a partition table. Step two: Add some partitions. At least one partition for the system (root---/), and probably a small one for swap. Maybe a separate one for /boot, maybe a separate one for /home. (I use LVM, so to keep things simple, I put LVM logical volumes inside a partition (rather than on a bare disk), and put /boot on an 8GB separate partition.) -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.
