no external disk access after lion-installation

[ffbkdavid]

hi - we run an MACBOOKPRO as well an a MACBOOKAIR... both under OSX Leopard - we provide accounting services to clients bringing their own disks formatted under WINDOWS NT DATASYSTEM (COMPRESSED) - no problem until yesterday, when we started updating our OS to OSX LION...

... no further access to the disks - remarks on the DISK-SERVICEPROGRAM:
- Mount-Point: no activated
- Format: WINDOWS NT DATASYSTEM (COMPRESSED)
- owner activated: -
- number of frames: -
- capacity: 499.9 GB
- available: -
- occupied: -
- number of data: -

*** sorry, system run in german, so translation into understandable it-english a little complicated

what could/should be done?

thanks for any support and help

If you have been using one of the NTFS drivers, such as NTFS-3G, then you could try updating that software. Here's a page that tells about the problem:
