before reflashing...u can try these things...

1) connect to windows pc and scan and correct drive errors
2) if u have backup of ur all data including contacts and all stuff...go to settings-->tap on drop down menu and select clear device...default code is 12345
3) if 2 of above donot help then flashing is the last option..

or if u have rootsh installed u can try this..

in xterminal type

root
umount /home/user/MyDocs
fsck -a /home/user/MyDocs
