Can't mount WD Passport hdd usb and sandisk pendrive after upgrade to Lion

I can't speak to the sandisk pendrive, but I have an iMac 20.5" late 2009 Core 2 Duo with 12 GB RAM and and a MBP late 2006 Core 2 Duo 3 GB RAM and my WD Passport USB drive works fine on both of them. I run my Carbon Copy Cloner daily incremental full backup to it.

Can you remove everything from USB for testing, including hubs, and directly connect the WD directly to one of the rear USB ports to see if that helps?

Also, what does Disk Utilitiy report? Does your disk show up there?

Hi, Berna.

The fact it is visible in Disk Utilitity is a good sign.

A few questions to help debug the issue:

• If you select the disk in the left panel, is the Mount icon clickable or is it grayed out. If it is clickable, does it report an error?
• What if you click Repair Disk Permissions? Are errors reported?
• If that is ok, What if you click Repair Disk? Are errors reported?

Let's try this next, ok?

By the way, does this drive have data on it, or is it a new drive you want to connect up? Is it a drive we can reformat if necessary?

OK. Here's a dumb question, but it can't hurt to ask!

All the symptoms are indicating that the disk is mounted:

(1) You see it in Disk Utility.

(2) Mount disk is grayed out (as it would be if it were already mounted).

(3) Repair disk works and there are no errors reported.

So... let's go back to the original premise - that the disk is not mounted. Why do you think it isn't mounted?

If you go to Finder > Preferences and click on General, are all these three boxes check?

• Hard disks
• External disks
• CDs, DVDs and iPods

I'm guessing now that maybe it's just not showing on the Desktop which is why you think it isn't mounted. Can you check that.

Berna,

I'm running out of ideas, but let's at least check this:

(1) In Finder > Preferences on the Sidebar settings, under Devices, do you have everything checked? (iDisk doesn't matter)

(2) If so, does your WD HD appear in the Finder sidebar, at the bottom (used to be on top) in the Devices section?

Is it just an issue using the drive in Time Machine? If so, could be the same issue I have with Seagate GoFlex home where AFP has been updated, but is not supported by the vendor (yet)...

Berna, going back to Disk Utilities for a moment...

I know you said if you select the disk "Mount" is greyed out and unselectable. Yet you were able to run Repair Disk on it.

What about "Eject" - is it also greyed out?
