External HDD Powered Hub

[renanpaiva]

Hello,

I'm trying to use my RPi as a print server and NAS, so I bought a powered hub and attach a first drive, my Seagate Expansion Portable Drive 500gb.

Please do not begin your post with a core dump-- that is rude.

Begin be describing the issue in simple terms (if possible) and let everyone go from there.

What is your problem | question?

[renanpaiva]

Sorry wasn't my intent, otherwise was simplify.

My problem is because I can't mount my external hdd.

I'm using a powered hub, It list in /dev/etc/ but don't appear in fdisk and I can't mount It.

Thanks

[MarkHaysHarris777]

I'm using a powered hub, It list in /dev/etc/ but don't appear in fdisk and I can't mount It.

Try to get the hub out of the equation for the moment... but make sure your power adapter is adequate. Only plug the hdd directly into your PI, but only if you have a power adapter that will provide enough current; at least 2A... I would recommend 2200 mA minimum. See if the hdd will mount without the powered hub. Not all powered hubs are equal.

Also, will the hdd mount anywhere else?

[PeterO]

Your syslog shows that /dev/sda has been created so you are nearly there Your hub looks to be is working fine, so ignore the advice to remove it as the person saying that hasn't actually looked at the log files you posted to see what is happening.

Can you run "fdisk /dev/sda"
and print the partion table with the "p" command.

PeterO

PS: The device resets at the end of syslog are a bit worrying, but lets sort out why it won't mount first.

Rather than being rude, it is exactly what we ask people to do, post some useful log files and run some useful commands.
All that was missing was the actual problem description which you could have asked for rather than getting on your high horse and putting down the OP.

[renanpaiva]

Peter first of all thanks a lot,

following the command that you ask for:

[PeterO]

OK so there is a partition table and it has a single partition defined.

I would expect "mount -t vfat /dev/sda1 /mnt" to work. "vfat" mignt need to be "ntfs" but I have no experience with windows filesystems other than using them on floppy disks.

PeterO

[renanpaiva]

Code: Select all

sudo mount -t vfat /dev/sda1 /mnt/usbdrive_fotos2/

mount: /dev/sda1 is not a valid block device.

this file system is exFat but I got same message using exfat.

thanks

[PeterO]

Ok, so now we know there is some data on the drive it is time to loop back to the topic of the power suppliy for the hard drive.

Some questions....

Does this drive work OK on any other computer ?

If yes to the above, do you use the same powered hub to connect the disk to that computer ?

What else (apart from the powered hub) is connected to the USB ports on your PI ?

What rating (in Amps) is your PI's power supply ?

PeterO

[renanpaiva]

Does this drive work OK on any other computer ?
Yes, with my MacBook Pro works fine

If yes to the above, do you use the same powered hub to connect the disk to that computer ?
With power hub and without works fine

What else (apart from the powered hub) is connected to the USB ports on your PI ?
A Samsung printer is connected and my power hub

What rating (in Amps) is your PI's power supply ?
850 mhA

[PeterO]

OK, well if it works on other PCs with the hub there is no point in trying it directly connected to the PI, plus your PI's PSU wouldn't take the extra load !

As a general point my first suggestion is to try a better PSU on your PI as 850mA is a bit too low (espcially for a PI 2).
Are you seeing any "low voltage" warning squares on the display ?

PeterO

[renanpaiva]

No any warning.

Ok all buy a 2A power supply.
