From: JF Mezei on 9 May 2010 21:12 Had a scary episode which rendered my GPS inoperative. Plugged the GPS into my Mac, set it to USB-disk mode, resulting in tge Mac mouting the FAT disk in the GPS' micro SD card. Got to see the various .GPX files as well as the map database file. However, the GPS would no longer reboot after that. Had to remove the card for it to reboot properly. Turns out it doesn't like some of the files/directories that get created by the Mac (.Trashes ._Trashes, .Spotlight and others). I was able to insert the SD card into the GPS and remount it, and use command line to remove all those hidden files, and then used the finder to dismount the disk (just trag it to the trash) and then the GPS rebooted fine. At what point does the Mac created all those hidden files/Directories ? First time the FINDER opens the disk ? As the disk is mounted ? or when the disk is first modified ? Is there a way to tell the Mac to never create those files for FAT disks?

Not to defend bad practices such as this, but I'd also send a separate note to the manufacturer of the affected device asking them why files that are clearly not used by the device should affect normal operation. -- Send responses to the relevant news group rather than email to me.

I was getting ".DS_Store" files magically appearing in my Eclipse projects and some inevitably found their way into deployment packages to cause various kinds of strange errors at deployment time. The problem was fixed in my case by switching to the Windows Eclipse platform for Java software development.

Any attempt at reading files on the internal memory or the flash card crashed the gps unit (due to the hidden Mac files according to Garmin support). I've solved the problem with BlueHarvest http://www.zeroonetwenty.com/blueharvest/ This very nice little app. will transparently delete all offending files from any non-Mac disks mounted. You can set it either to do this automatically (as I do) or manually if you wish. Problem solved! It's worth every penny or cent of the $16.95 license. -- Mike Lane UK North Yorkshire email: mike_lane at mac dot com |
