Bought a LEXAR USB 3 dual card reader and it doesnt work at all on my new 2012 MacBook Air. Works fine as USB 2 on old Mac Pro Tower. LEXAR blames Apple's new USB 3. Awaiting updates from both companies.
MacBook Air, Mac OS X (10.7.4), 2012 w/USB 3 i7
I have a mid-2012 Air (120gb SSD/8gb RAM) and have had mixed experiences with USB 3 external HDDs.
I am using a WD 750GB external HDD partitioned for Time Machine and "mobile" backups of files, software etc = all good, no problems on USB 3 port on Air.
I also have a WD 3TB Caviar Green HDD in a mains-powered enclosure - sweet drive, quiet etc but the USB 3 port on the Air doesn't have the power to drive the WD drive (even with main supply). To access/use the 3TB drive, I have to connect it through a mains-powered USB hub.
Without the hub, I can hear the drive spinning up/spinning down and am unable to copy files to/from Air. Connected through powered USB hub, all is good.
any thoughts? anyone else with similar experiences?
Same here: an extrenal WD 500GB USB 3.0 drive runs fine. A Corsair SSD Force 3 128 GB in an ICY BOX USB 3.0 case sometimes doesn't get recognized or looses connection while copying/standby - unusable.
The same Corsair SSD works fine with an older USB 2.0 case. For me it looks like certain controllers won't work.
Yes... same problem here... Verbatim 64GB USB 3.0 Store and Go' flash drive and MBA 2012 8GB RAM, 128GB SSD and it started to read and write just fine, then all of sudden stopped working ont he first day of use. Verbatim pointing to Apple... Lots of calls with Apple and we've tried just about everything. No resolution yet, but was mentioned that they are seeing various reports of this issue, and we could likely be looking at a firmware upgrade for these Airs soon...
