I bought a SATA to USB3.0 connector for an external HD and just realized the maker's OS designation is Windows, not Mac. Plugged it -- with the HD attached -- into my Macbook Pro and got the message "the disk you inserted cannot be read" so I reformatted the drive on Disk Utility to Mac OS extended journaled. Ran verify and repair disk and all seemed to be OK. But when I tried to run a Time Machine backup to it, the backup failed and the message said the disk was ejected improperly. This happened twice. My question is, are these dongles specific to an OS -- Windows, Mac, etc. -- or can they be reformatted. Hope someone can help.

To help you I need to get some clear information.
"SATA to USB3.0 connector", "external HD" and "these dongles" . When you say "dongle" I asome you mean the "SATA to USB3.0 connector".
Am I right your external HD has gote a E-SATA connector on it? What make and model is it?
Your "SATA to USB3 connector" is marked for use with Windows? and you call it a dongle (witch is something else)
After re-formatting the external HD (not the "dongle" you can't re-format a connector) the message was "disk was ejected improperly"?
If this is all right then it may be (in no order these idears will help):
1) The connector should be "E-SATA to USB3.0" most external HDs are E-SATA "External-SATA" and not SATA
Exchange the SATA connector for a E-SATA one.
2) The connector was disconnect from the computer and reconnected without properly ejecting it, before Time Machine was run
Make shoure you eject and disk you connect to the USB port befor disconnecting them.
Two ways of doing this:
ONE: if the disk appears on the Desktop drag it to the Trash befor unpluging it.
TWO: in finder right click it and click on "Eject".
If this error happens again then run "repair disk again"
3) The "SATA to USB3.0 connector" IS! windows specific. May be;
Get a replacement.
What make and modle? and I'll try an check.
I hope this helps and sorry for the spelling I am dyslex....
