GParted ...

Since 2 years we have a 3TB USB drive which I divided into 4 NTFS formatted primary partitions of almost 700 GB each. In Slitz3 the 4th partition was never visible or accessible, which probably had to do with the old kernel. But the first 3 partitions worked fine. In Slitaz5 all 4 partitions have always been accessible.

Yesterday I cleared out partitions 3 and 4, and re-formatted them with ext4, so as to preserve the permissions. I then copied lots of stuff to the new ext4 partitions and, as before, everything was ok in Slitaz5. But strangely, in Slitaz3 I can now only use the first 2 partitions. Partition No.3 doesn't show in PCMan and GParted. Does anyone know what's been happening there?

Re: GParted ...

Hi, for my little experience, the bug get out from fstab. Seem wrong stored same partition as same device... (slitaz3 not use UUID)

IMHO

Re: GParted ...

Thanks for your reply, gibor. Yes, it may be something like that, although my fstab in Slitaz3 doesn't even specify any USB devices ...

But who knows what's going on when an external USB drive is plugged in? It had never occurred to me before but I just ran a simple fdisk and found that I can actually see all 4 partitions of the external USB drive ...

... hda1 is my infamous 1GB Seagate drive and sdd1-4 are the four partitions of the 3TB WD USB drive. But what ever I try I cannot mount partitions 3 and 4, which is probably the reason why neither PCMan nor GParted even show them.

But I do not want to create too much fuss about the whole thing as everything works fine in Slitaz5.

Re: GParted ...

Easy on my case fstab store the partition swap... if I connect a device in a content a swap partition, this are stored on fstab.

All usb memory stick are /dev/sdxx, and all serial usb hardisk are marked sd... (a,b,c,etc.)

On next case if a insert new disk have partition on same position but not formatted swap, not working why are already marked of fstab as swap. And pcmanfm not view any partition marked swap.

But its only my case...
