[...] I'd start with the hardware. Does it improve/stay the same when you hook it back up via e-SATA? If it is not possible to do that with your current hardware, then consider removing the drive and direct connecting it. The suggestions by the other posters to make a drive image is a good one. You will have both a backup and you'll be able to run various recovery tools on that image. You can even try mounting that image in read-only loop back mode, and see whether you're still experiencing problems. If everything works fine, then it suggests that the hardware isn't working. Of course, if you are able to image the drive completely that suggests the drive is working at some level, and the failure you're seeing becomes more difficult to explain. That's why I'd recommend direct-connecting it, and trying to make an image, pronto. We have seen USB/eSATA enclosures fail in some rather unpredictable ways. One common failure is the small fan that is present on some enclosures quits spinning and either the controller electronics, or drive overheat ... leading to erratic results. Power supplies (wall warts) often seem to be the weakest link. And those self-powered USB drives, even with the two USB connectors can run into problems at the margin. Using the supplied PSU usually fixes that problem. Finally, we've seen problems with Firewire/USB add on PCI cards - they worked fine for a year/two and then just quit working, or had glitches. |
