Re: [solved]Impossible to make an ext4 file on large external drive
I managed to get what I wanted : ext4 files.
How ?
1) I run : sudo cfdisk /dev/sdc
---> new, type:linux
2) I check the path : sudo fdisk -l -u
3) I run : sudo mkfs.ext4 -j -O extent -L backupdisk /dev/sdc1
Why ?
Who knows ?
Solution is not satisfying.
Wonder if these troubles come from power supply (only one usb2 cable for such a large disk capacity)?
Last question : how to mount this disk as my PC Linux does not recognize ext4 ?
(before I upgrade to 9.04.)
i had the same problem and this also was the only solution that worked for me but i kept getting errors messages like "ata.4:SRST failed[error=-16]" but wasn't aware of the real cause of the problem.then one day i recgnized that one of my disks jumpers connected as slave is not set properly .so i set the jumpers right and update dmi pool and then: WOW.the machine is working great with no slow down or ATA.4 error messages(i expect you get them too) .this is when i decided to reformat the faulty disk in normal way using GUI Gparted.it's amazing ,it worked at last in less than 15 min(as expected for healthy disk as such).i hope this could help you
