Plugable U3 docking station stops working after a few hours. It’s on, but file transfers just stall. I had this problem in both Windows 7 and in Ubuntu. In Windows 7, this inevitably results in a message saying the drive can’t be found and when clicking to continue or skip it still can’t find anything and trying to navigate the file structures doesn’t help.
The best workaround I could find is to use TeraCopy to handle file transfers to the drive because when this happens I can view a list of which files completed successfully so I can at least manually select which files to continue. As long as I physically turn the drive off and then back on again it works again for a few more hours. It seems to be some kind of power saving feature gone horribly wrong. I have all firmware updates applied. Hard drive in use is a Seagate Barracuda XT 4 TB. An old model which still uses 512 byte sector size. Using 2 Partitions, each Primary/Fat32 set to 1.8 GB. GPT.
As a side note, I really don’t like the Docking Station form because it lacks a fan. Maybe the design could be improved by having a cap with a fan on the top placed over it to suck air up and away with maybe a gap between the drive and base held firm by little edges. Such a form would help the drive run cooler and allow it to continue to function as a Docking Station, but could be “closed up” like a normal external hard drive for more continual use. Honestly the only reason I am using this instead of one with a fan is because so far it’s the only one that seems to properly support 512 byte drives at 4 TB. If such a product already exist, or if you have fan model that supports 512 byte drives, let me know and I will buy it.
