I've been getting errors when I try to analyze and defragment and when trying to use the flash card for our digital camera. When trying to use the falsh card< I get the error F:\DBIL is not accesible. The file or directory is corrupted or unreadable. When defragmenting and analyzing, I get similiar error messages. I don't know how to fix these. I have tried chkdsk, but maybe I am doing something wrong. Any help would be great. Thanks.
