Linux recognizes external HDD connected via eSATA but not via USB
yesterday I connected an external HDD via eSATA to my notebook. I formatted the disk and created an NTFS filesystem on it. Afterwards I copied a bunch of datas to this disk. Everything worked fine.
Today I connected the disk via USB and my system didn't recognized the NTFS-partition, so I couldn't mount the device. A Win7 system declarated the disk as "RAW".
When I connect the disk via eSATA again it is recognized by my Linuxsystem and I can access the datas on it. That's very strange and I guess I haven't understood the technology at all?!
My system is a LinuxMint 14 (64-bit).
Can anybody help me?
