CrunchBang Linux

I solved this write-protection in a very simple way, after trying all these complicated tips without success!

In my old but good Fujitsu Siemens laptop with amd64 processor and latest Debian squeeze system, i just installed package "ntfs-3g" with packet manager (Synaptic)  .  Before that, external HDD:s mounted automatically and were readable mut allowed not write anything.  After that little package installation, all worked perfectly.  HDD:s were 500 Gb WD MyPassport and Toshiba.

It take me one week work to solve, what a moron I was!  Hope that someone else finds this helpfull, life is too sll hort for this kind of time wasting!  I still wonder why this ntfs-3g packet was not installed by default in squeeze?

certainly there is many different reasons for this problem in different hard/software systems, so this helps only in some cases.
