[RT-N66U] change sdb5 to sda1 etc.

[SnoPoX]

Hi
I have attached an external USB HDD to the router but unfortunately after a power cut (also after reboot) the "mountpoint" (dont know if thats the right term) changes. Sometimes the router shows my HDD as sda1, sda5, sdb3 and so on, the name changes.
The bad thing about this is, that i created some scripts using the "mountpoints", so if the name changes from sda1 to sda5 my scripts dont work anymore.
Is there a way to manually rename the drives or prevent the router giving them new names?
Or do i have to change my scripts?

I am using Merlins RT-N66U_3.0.0.4_374.33_0, the external harddisk is a 2TB NTFS HDD and I hope there is a way to do it without formatting my harddisk I also leave my HDD always in the same USB Port.

Thanks in advance!

Did you set a label?

I did not set a label (well, at least not that I know).
I am on Windows 8 and if I look after shared network drives, then I see \\RT-N66U\sdaX
Via telnet (putty) I can see that the harddisk is mounted as "sdaX" (where X is a number). Sometimes its sdb or even sdc, unfortunately I cant reproduce this behaviour everytime. I rebootet the device quite often and for now the harddisks' name/mount stays "sda5".

That means that disk has multiple partitions. sda5 typically appears under Linux if your disk has both primary and extended peratitions, and this would be the first extended partition.

Just set a volume label, that way the disk will mount under /mnt/label instead of /mnt/sdaX.

Thank you both! I've tried to set a label with tune2fs, but it didn't work out well:

admin@RT-N66U:/tmp/home/root# tune2fs -L Test /dev/sda5
tune2fs 1.42.8 (20-Jun-2013)
tune2fs: Bad magic number in super-block while trying to open /dev/sda5
Couldn't find valid filesystem superblock.

Meh, guess I've done something wrong. The harddisk has a NTFS Filesystem, maybe thats the reason.

Use Windows to set a label on an NTFS volume. Properties on the drive from within the Computer window.

Thank you.
I was wondering why it didn't work since the device got a label when it is connected to a Windows machine via USB.
I figured it out: just don't use a dot "." in your label name. Naming conventions are just not my cup of tea Now everthing works fine!
And don't hit me
