Artemis has an iMac, it was coming up on 3 years old, and it had never been backed up. Worse, it was running Tiger, which does not have Time Machine, and it makes no sense to consider upgrading to Snow Leopard until she already has a backup. I decided to remedy the situation by sending her an external USB drive for her birthday. The drive arrived, the birthday passed, the holidays came, school started again, and the drive had still never been connected. Last week the opportune time came.
I had sent a drive which was twice the size of her internal disk, so I recommended partitioning it in two. I sent detailed instructions with images about how to use Finder and Disk Utility and Carbon Copy Cloner. I was certain that this would be a straightforward procedure, even for someone who didn't know the terms USB mass storage or disk partition.
Artemis proceeded, but she kept reporting that even when she unmounted the disk partitions the iMac kept warning her that she had not disconnected properly and might lose data. Then she reported one thing I could not have expected -- the Finder was showing something like a brain which vanished when she unplugged the USB cable. Worse, she reported that when she ejected the brain, it came back again.
I had bought her a
drive from Western Digital, and that was enough to send me asking google what they knew. I found that
others, including
Mac owners had already been through this experience.
I managed to buy this drive during the first weeks of its availability, and it has a new feature -- a "Virtual CDROM" (VCD) which contains their backup software. The firmware in the drive presents it both as a USB mass storage device and as a CDROM. Within 6 weeks the vendor offered a
patch for the firmware to disable the VCD. Perhaps if I visit Artemis I'll bother to do the firmware upgrade, but for now I've simply said to use the power switch on the drive after unmounting the disk partitions.
From the blogs above it's pretty clear what happened. Customers started bringing these drives back to the big box retailers with complaints that they did not act right. The big box retailers called the manufacturer and said "they're returning your drives, fix it". The manufacturer acted fast to do that.
It's not that the space consumed by the VCD is a big deal, for only one tenth of one percent of the capacity of the drive is being used for their software. It's the principle of creating a product which foists unwanted software upon the user. It's more than that.
By setting up the firmware such that Mac OS X repeatedly remounts the Virtual CDROM even when the user repeatedly ejects it the manufacturer created a little yapping dog. It's a little yapping dog that keeps coming back to hump your leg every time you kick it away.
