FAT32 USB 2.0 drive mounted but neither FTP nor SMB shares working

[2000wolf]

Hi there, I've got another strange issue:

My USB drive is detected and mounted (according system log) but when I go to the Media Server pages where I can activate FTP or Samba shares and add user accounts etc. that drive is not available.

Am I the only user suffering from that issue?

As mentioned in other posts (no guest WLAN...) my RT-N66U behaves a little bit strange though clearing NVRAM after flashing .178 and afterwards .178.15.

Does the drive have either multiple partition, or is a drive that comes with a special "hidden" partition that emulates a CD-ROM drive (some do that to store special backup software on it)?

What does the following command returns (change sda for sdb or sdc depending on what device your USB disk is):

echo "p" | fdisk /dev/sda

Hi RMerlin,

Thank's for your fast reply; that are the results :

The number of cylinders for this disk is set to 1096.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

Command (m for help):
Disk /dev/sdb: 8044 MB, 8044675072 bytes
256 heads, 56 sectors/track, 1096 cylinders
Units = cylinders of 14336 * 512 = 7340032 bytes

Device Boot Start End Blocks Id System
/dev/sdb1 * 1 1096 7855044 b Win95 FAT32



... and echo "p" | fdisk /dev/sdb1 provides the following:

Partition table entries are not in disk order

 

[RMerlin]

From what I can see there's indeed only one partition visible. Have you looked at syslog for any actual error message that might give a hint as to what's wrong?

That second fdisk command returned garbage because you told it to display the partition table of a partition - that doesn't work, the partition table is only at the actual device level, not inside a partition.

Hi RMerlin,

That's my most current syslog:

Can you detect something strange?

 

[RMerlin]

Nothing particular in that log. Maybe something related to the drive volume name? Try renaming it in case it might have some special characters in its name that doesn't agree with the webui.

What does the following command returns (change sda for sdb or sdc depending on what device your USB disk is):

On a side note, you can use fdisk -l /dev/sda instead of echo/pipe ;-)
