Alina Posted December 31, 2007 Share Posted December 31, 2007 Hi, does the wear leveling works with the ext2 filesystem? My question ist, how does the chip know which block ist free. This is a filesystem specific thing. Or does it treated a block which only contains zeros as free? Regards Alina Link to comment Share on other sites More sharing options...
Alina Posted January 1, 2008 Author Share Posted January 1, 2008 Hi! In the USB Flash Drive FAQ I can read the following: Corsair’s flash drives typically use dynamic wear- leveling. But CMFUSB2.0-4GBGT say: Wear Leveling: Static wear leveling What is now right? If it really use static wear leveling I have no Problem with the ext2 support in wear leveling.

Corsair Employees RAM GUY Posted January 2, 2008 Corsair Employees Share Posted January 2, 2008 I am sorry but that was a mistake on the Data Sheet and I have asked to have it corrected our Drives all use dynamic wear-leveling at this time. However that may change in the future. Link to comment Share on other sites More sharing options...
schnittig Posted January 29, 2008 Share Posted January 29, 2008 Hi RamGuy! I also read the technical information about the function of wear-leveling like implemented in the usb flash drives. There is no problem for me to understeand, that data is always written to an first empty cell with the tiniest write count and the original cell is marked as free. But what is, when a file is deleted? In case of a FAT32 filesystem only the entry in the file allocation table for the file is deleted. The memory cells are still marked as non-free. So in the course of time there will be no memory cells which are marked free. Do you understeand what I mean? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted January 29, 2008 Corsair Employees Share Posted January 29, 2008 The way the file system works that will not happen unless you keep the drive 90% full or more all the time, and then it would just rotate the free blocks.
