External HDD

_blank_

I have an external HDD plugged into my Linux Mint box, but when I go into "Computer" on the desktop, I can't see it.

Am I looking in the right place?

Open a terminal. A few seconds after you've plugged in the hdd, type "dmesg" and press enter, paste the last ~10 lines here.

Hm. With the HDD connected, could you paste the output of

sudo fdisk -l

hmm, is that a number 1 or a lower case Letter L?

So there it is. It doesn't show up anywhere? Restarting PC doesn't help?

Hi.
Can you unplug your webcam, unplug and replug the external HDD, and
tell us what lsusb lists out.

Can you also post up the model of the harddrive, and confirm whether you're connecting it via USB, firewire, eSATA, SCSI or whatever.

Can you confirm the cable and drive work on another machine ?

Nope, it's integrated into the screen. It's a laptop.

will post it in a minute.

No idea of the model, it was scavenged from an old laptop and I stuck it in a caddy.

It definitely works on another (Windows7) laptop. I have two files stored on it at the moment, for testing. A picture (jpeg) and a mp3 music track.

The other day before I posted here, I had formatted the HDD to remove all the info stored on it, and was able to copy both these files to it. I was advised to format using FAT, not NTSC

Assuming that /dev/sdb is the disk in question, then the partition you want to use is /dev/sdb2, and you need a driver that can handle NTFS. Since Mint is a modified Ubuntu, I'm reasonably sure that the package you need is ntfs-3g, with its dependencies. I suggest installing that, rebooting, and trying again.

Or, if there isn't anything on there that you need, I'd blow it all away and repartition with VFAT.

Hi,
just checking back in.
If I'd realised the computer was a laptop, the first thing I'd have suggested is to make sure it's getting enough power. You can get a two way USB cable to supply with power from two ports if there's not quite enough in one, or you can often get an external power supply for them.
That said, it looks likely that sdb above is the one you want and it's at least detected.
If power is low though, it may disappear when you try to write to it!

There's a comment here from someone with exactly the same enclosure where he says:

Mounting an external hard drive
I have a 2.5" enclosure that's powered off the USB ports. I'm unable to get it to mount, however I can get it to appear in the lsusb:

Bus 002 Device 005: ID 04fc:0c25 Sunplus Technology Co., Ltd

Occasionally I can get it to appear, but it just quits after a few moments. Any ideas?

ok, I'll try this. Thanks

Oh, then I probably should have mentioned, it already has two usb cables attached, one looks specifically like it's for power.
