What disk drives will work with the NeXT?
disk drives There are some situations in which there are problems. Here is a short list which might help you in your disk drive quest: * These drives don’t work with NeXT hardware: FUJITSU 2684SAU, SEAGATE ST51080N, IBM IB06H8891 * The SCSI driver for NeXT hardware only accepts asynchronous data transfer. Although every new SCSI-2 drive should support this mode, this isn’t true for certain drives. Also sometimes there is a hardware switch (a little jumper on the drive) which switches between synchronous and asynchronous mode. You definitly can only use asynchronous disks! * There are also problems with sync negotiation on NeXT hardware. In general there should be another jumper to toggle this are you might change this with an SCSI utility. There are also problems with the tagged command queuing option. Anyway all these problem can be solved. Often these problems arise with IBM drives. We recommand to look in the technical documentation of the drive, which is available only from IBM’s W
