Thanks I am using your method as you described and it works very well for my thumb drives, but does not work for my external 160gb hard drive. The drive is recognized but no files are accessable. It could be because it has multiple Fat32 partitions. I don't know. Later I will try another hard drive that only has a single partition. Anyway thanks for the advice.
Your welcome. You need to have patience my 1tb hard drive has 300gb of music on it. It takes it some time to check for errors (listed in notification bar), but it does complete. The PowerAMP music program next takes a lot of time to scan and catalog the music folder each time I mount it. Again it completes.
Edit: I just dismounted two flash dirve with the busybox command and then mounted the 1tb external hard drive with no problem.
