HP C1537A cannot store >12GB

[Stephan Paukner]

We have two identical HP C1537A DDS-3 drives, both of them are not able to store an amount over 12GB on a 125m 4mm DDS-3 tape. We tried with different controllers (Adaptec, NCR) on different Linux-machines (SuSE, 2.4.18), but the result is always the same. The compression test by the LTT software passes successfully (ratio is slightly above 2:1)

Does anyone have a solution for this?

Hi
the compression depends on the type of files that you are backing up.

what kind of files are you trying to back up?

Indeed, I found out that most of the files are already present in a compressed format (JPEGs, zipped,...), so that could be the reason.

Thanks!
