How to use diskutil to verify USB drive attached to Time Capsule?

[philcyeung]

Hi. I have an USB external HD attached to Time Capsule. Trying to find out how one can use diskutil to do a verifyVolume on this drive.

I tried something like:

diskutil verifyVolume /Volumes/myDrive

but it didn't work

The command is (naturally) ok with an USB external HD attached to the USB port on the Mac itself.

Thanks in advance.

Well, is the drive even mounted?

ls /Volumes

Yup, I clicked through Finder so that it's mounted:

Volumes Family$ ls -al
total 8
drwxrwxrwt@ 5 root admin 170 Jan 8 11:31 .
drwxrwxr-t 33 root admin 1190 Dec 16 02:47 ..
lrwxr-xr-x 1 root admin 1 Jan 8 10:28 Family's Macintosh HD -> /
drwxrwxr-x 11 Family staff 442 Dec 2 18:21 My Book Primary Volume
drwx------ 17 Family staff 534 Jan 8 08:15 My Book Secondary Volume

I can do a diskutil verifyVolume on "My Book Primary Volume", which is attached to the USB port on the iMac itself, but not "My Book Secondary Volume" which is attaching to the USB port on Time Capsule.

Here's the output when doing the two verifyVolume:



Volumes Family$ diskUtil verifyVolume "My Book Primary Volume"

Verify or repair the file system data structure of a volume.

VerifyDisk and repairDisk are allowed but deprecated synonyms for
verifyVolume and repairVolume, respectively.

Basically the second time it just show the 'usage' text.

Thanks.

Okay, try running

sudo chmod a+rx My\ Book\ Secondary\ Volume

Yeah, thought about that also earlier. Just tried it to no avail. It's ignoring the chmod as well.

So I tried to unplug the USB HD from Time Capsule back to the iMac, and the permissions got set to rwx for 'u' and 'g', and rx for 'o', the same as the USB HD which has been connecting to the Mac from the get go, and diskutil was able to do it's thing.

Connecting it back to the time capsule, and all got reverted back, and diskutil was ignoring it again.
