Hey there ! I have been looking for a DAT , and have looked for second source DAT's as well do anyone have experience with installation of non HP DATs on a HP9000/s300. I am looking at a GigaTape (German product) which has a standard SCSI interface will it be possible to make this work ?. My second question: do anyone have experience with the compressing DATs I have seen products capable of storing upto 8 GBytes on one tape, is it more riskfull than the standard of 1.3 GBytes ?? Thanks in advance Dan Soren Nielsen, ElektronikCentralen, venlighedsvej 4, 2970 Hoersholm, Denmark Disclaimer: This request is not an expression of the polecyicy of EC, or me

I believe that the original GigaTape product uses a proprietary format that is not compatible with the DDS format used by HP and most other DAT drive manufacturers. I believe GigaTape were working on a DDS drive, but I have not heard of any announcements from them. The other main manufacturers of DDS SCSI drives are Archive and WangDAT. I do not know whether these will work successfully with an HP9000 s300, but they have generic SCSI interfaces. >> My second question: do anyone have experience with the compressing >> DATs I have seen products capable of storing upto 8 GBytes on one >> tape, is it more riskfull than the standard of 1.3 GBytes ?? The data compressing drives have the same error rate as non-compressing drives. That is, the proportion of host data that would be unrecoverable due to a failure is the same whether it is compressed or not. The addition of the compression hardware potentially adds an extra point of failure, but the chance of such a failure is so small that it does not affect reliability.
