Hey guys. I own a seagate GoFlex Net which uses this same pogoplug service. I am runnig mac OSX 10.6. I recently ran into this also. For weeks I have been trying to figure out why my drives where no longer showing up. Yesterday I discovered something that answered my question. I recently set up my MacBook Pro to run in 64bit mode. Since then I have not been able to mount my pogoplug disk to my desktop. Then digging around in my computer I was cleaning files and getting rid of stuff I no longer needed. In the past I have installed MacFuse on my system and thought I no longer needed it so I uninstalled it. This caused the pogoplug app to show a error message. When researching the error I discovery I needed MacFuse for pogoplug to setup file directories on my mac..OOPs. I also realized that when you install the pogoplug software it installs a 32bit kernal of MacFuse which does not properly operate under the 64bit mode in OSX.(At least not for me) There is a 64Bit MacFuse which is hard to find online. I tried installing it but I still have no luck with mounting the pogoplug drives in 64bit mode. All is well in the 32bit mode of OSX. It would be great if someone can look into this to get this working in 64bit so I can use all my 8GB of ram I purchased and to use for my other software.

Let me know if you guys have any luck with this.

you can force your mac into 32Bit mode by holding down the keys "3" and "2" together before startup.

I've been having the same problem for months - in fact, my PP (Pink) worked great when I got it, but I thought it had failed. I'm trying to figure out how to force a firmware upgrade. The software is working - a friend's files that he shares are still available to me. My PP still tells me there is no drive attached - and I have four on it now (even when I have one, it doesn't work.) I'm in 32 bit mode on a MacBook Pro. Today I updated MacFuse. Still no joy. Beginning to think PP can't keep up with software upgrades. Hoping someone else broke through this roadblock.

Just activated a Pogoplug Biz and getting similar error "no drive attached" .. but there is. Have now tried with three different drives that all mount fine directly to the machine. (Mac OS X 10.6.6) and have verified all with disk utility.

Not sure if it is related but we noticed also that we cannot copy a file to the drive using the local Pogoplug app without getting error message "One or more items can't be copied to "Files shared with me" because you don't have permission to read them". Of course we checked and we do... there is only one Adminstrator account on this Mac in any case.

Has this first problem been open since December or are there fixes posted elsewhere? We would really like to try the Pogoplug out. The videos make it look easy... We don't feel real smart right now. Thanks!

I also got it working, but by actually rebooting the PogoPlug. I verified my drives many, many times and ultimately, in a fit of frustration, just unplugged the PogoPlug. When I plugged it back in, everything just worked.

I bought my Pink Pogoplug yesterday. I'm having the same problem, my Pogoplug can't find my USB drive (500GB) nor any of my 3 thumb drives. The device can be registered with no problem, so it must not be a connection problem. I've tried unplugging the Pogoplug, but still no luck. If this continues, I'm gonna to get a refund tomorrow, and will Blog my (FAE) less than prefect review on the device.
