How to mount a hard drive dock?


I have a NexStar dual bay hard drive dock, model nst-200.
I am using Crunchbang Waldorf 32 bit

I have tried to mount a Sata hard drive with this dock without success. I don't know how to trouble shoot this and haven't found any help on the Net. How do I go about this?

When I plugged in the dock a device showed up in /dev/sdf1
I don't know what filesystem is on it. I tried to mount it with ext4 and ntfs-3g.

Thanks

Is this a new drive? It may have no file system on it. In this case, you can partition it if you like, and format it. Then you will know what file system you have.

It would also help if you ran the commands you say didn't work, and post the output from the system, so we can see the error messages that you get. Without useful information like that, it is difficult to suggest much else.

If this is an used drive, and you have no idea what is on it, go ahead and format it, then try to mount the drive. You are doing that as root, correct?

Hi,

Is this a hot swap dock?

Make sure you have drive in one of the bays then do a 'fdisk -l' from cli to show available disks. You can look at the type of partition via ID and System listed if the partition has been prepared for use.

Then use 'df-T' from cli;
Code:
df -T
Filesystem     Type    1K-blocks    Used Available Use% Mounted on
/dev/sda5      ext4      3030800  900432   1973084  32% /
/dev/sda6      ext4     10190136 5794380   3871468  60% /home
/dev/sda7      ext4     10190136 7784572   1881276  81% /usr
/dev/sda8      ext4       999320  398972    547920  43% /var
/dev/sda9      ext4      3997376  305144   3482520   9% /tmp
tmpfs          tmpfs     8148576       0   8148576   0% /dev/shm
/dev/sdb2      fuseblk  14337020 7705372   6631648  54% /mnt/win7
Note the filesystem listed for one of my disk partition(s) above.

Whenever I try to mount /dev/sdb with the cli or scan for devices with gparted it just hangs. df didn't pick upp /dev/sdb1. Is this info helpful?

Thanks

This device is appears to be e-sata, USB-3. Is that correct?

I'm thinking this may be a device driver problem. Not sure, and I have no experience with such a device.

Is this the device?

It looks like it, but the model # is different. Mine says usb 2.0 and eSata
I couldn't find any particular info on this model.

It looks like your system needs ahci.ko loaded as a module, or compiled into the kernel.

I run Slackware, and its compiled into the kernel. Here is what is in the kernel config for Slackware.

Quote:
#
# Controllers with non-SFF native interface
#
CONFIG_SATA_AHCI=y
CONFIG_SATA_AHCI_PLATFORM=y
CONFIG_SATA_INIC162X=y
CONFIG_SATA_ACARD_AHCI=y
CONFIG_SATA_SIL24=y
CONFIG_ATA_SFF=y
I also did some reading, and some of these devices need proprietary drivers supplied my the manufacturer. I have no idea if this is the case with this device. Best advice I can give here is to look at the documentation that came with the system.

If you need guidance on how to look at the kernel config, or if the module is loaded, post that request. I'll see if I can help.

I don't know where the modules are located, not that familiar with drivers.

Turned on dock and hooked in usb after 10 min

gparted had a warning label, not sure what that is for. It said filesystem was clean

How do I find the name of the module to load the driver?

Quote:
modprobe ahci.ko
This command looks correct, however, I don't remember if adding the .ko on the end is necessary. You can try the command without the .ko on the end.

What kernel are you running? To find out, run the command as root 'uname -a' and post the results.

When you run modprobe it looks in
Quote:
/lib/modules/`uname -r`
If the kernel loaded is not 3.2.0-4-486, that would explain the 'not found'.

modprobe ahci loaded the driver. Gparted will recognize the drive, but I can't get it to format or mount the drive. Maybe it's the drive that's a problem; I'll have to check into it.
