In my experience this behaviour is caused by either not having an external power supply, or by having one that functions badly. In most cases external disks, especially large ones, need their own power supply. Look into that. Or contact the retailer/manufacturer directly and report this.

As far as the disk corruption goes, that isn't surprising. You could try iRecover to copy files to safety, but only after having fixed the disconnection problem. Do not run chkdsk or any other "repair" software. People who offer that particular advice have no idea what they're talking about, and they seem to mainly hang out in the type of forum where you asked the question. Avoid.

I found out i am getting CRC errors. Any way to fix them?

[Tom]

Depends on the type. Any chance you can create a health log? For that to work the disk must be connected directly, so not over USB. Info: http://www.diydatarecovery.nl/dp_manual/guide_smartcheck.htm

Usually this indicates a physical problem with the disk, so if possible, find out what the disk's health is. How old is this thing, can you get it replaced under warranty?

CRC errors can be 'fixed' as long as there are spares. Question is how did those sectors become corrupted in the first place? If the disk disconnects in the middle of writes that could explain them.

Fixing them will cause data that's stored in such a sector to be deleted (see http://www.diydatarecovery.nl/dp_manual/surface_scanning.htm).

If there's data on the disk that needs to be recovered, attach the disk directly to a PC motherboard and recover the data first.
