FreeAgent GoFlex Desk 2 TB usbdrive - device not ready
O/S:RHEL 5.3
I'm having issues with setup of a new Seagate 2 TB usbdisk. Onced i created partition and fileysystem, then mounted the disk, used rsync to backup test data to this new device. Early on, everything works, but shows problems fairly soon afterwards. Over a few days of testing, I've tested with variety of partition sizes. Here is some output which may be useful lsusb command returns info for this device: Bus 002 Device 003: ID 0bc2:5071 Seagate RSS LLC PARTED used to make a small partition on this device (size 1.4 GB) and filesystem (type ext2). parted command "test" showed clean file system. Mounted new partition (smaller than 2 GB for testing) /dev/sdc1 1.4G 30K 1.3G 1% /mnt/backup Parted commands (parted) unit GB (parted) mkpart Partition name? []? File system type? [ext2]?

You can use "sdparm" to query and set the spin done parameter. Looks like the drive might go spinning down in to power save mode and then not waking up fast enough. This is typical with certain FreeAgent drives and certain linux kernels. I have a FreeAgent USB drive I bought a few years ago and had a very similar problem. Newer kernels supposedly fixed this issue...
Here's some info I dredged up a while back on one or another distro forum (I don't remember which). Check sdparm man page too: Code:
