It works. I'm currently using both an IBM 34560 LVD (4.5GB) and an IBM 39130 LVD (9GB) in SE mode (I ordered "wide SCSI drives" and my vendor shipped me LVD ones ;-). They're very nice, and are attached to a Gigabyte 6BXDS (Adaptec 7895) motherboard. I also have another plain F/W (not LVD) IBM 39130 on the same SE bus, and I'm using vinum to stripe the LVD and plain F/W 93130 drives. They work well. The only thing to note about LVD drives is that they have *NO* provision for on-drive termination. All termination must be provided elsewhere. -- Darryl Okahata darrylo@sr.hp.com DISCLAIMER: this message is the author's personal opinion and does not constitute the support, opinion, or policy of Hewlett-Packard, or of the little green men that have been following him all day.
