The devince contains files written by a Linux system, mount= ing the USB Flash via extended4fs, the size of the written datafiles is > 128GB. Deleting tho= se files larger than some 20GB results in an I/O error reported by FReeBSD (# sudo rm /mnt/= USB/filename). Unmounting the ext2fs after deletion (sudo umount /mnt) results in a total = freeze of the box. No crash, no core dump, nothing. I waited almost an hour hoping for recover= . I have to physically switch off the box. I checked with other USB flash I have at hand, one Samsung 256 GB, ZFS - no= problem, another 128GB, UFS, no problem and several much smaller (4 - 64GB) with FAT or UFS = filesystems, all no problem. I can not figure out whether it is the USB flash drive itself, the size or = the ext2fs itself causing the problem. Does anybody see similar problems or do have an tip to investigate without = risking my box' health switching it on/off on failure?
