NeXTSTEP Disktab Entry for Iomega Bernoulli

This is from Doug Mitchell ([email protected]).

When using 150 Mbyte cartridges with a Bernoulli box which has firmware revision T.47, no further special procedures are necessary. If you insert a blank 150 Mbyte cartridge, Workspace Manager will ask you if you want to initialize it. You can initialize it with either a Mac or a NeXT file system. (An indication of non-Rev T.47 firmware is when you insert a blank 150 Megabyte cartridge and Workspace refuses to initialize it, ejecting it instead.)
When using any other size cartridge, or a Bernoulli box with other than Rev. T47 firmware, you must initialize the NeXT file system manually, using the 'disk' command. The Workspace Manager will not be able to initialize a NeXT file system on these drives automatically. To perform this operation, do the following before inserting the Bernoulli box cartridge:
1. Open up a Terminal window.
2. su to root.
3. Type the following:
```
disk -t iomega-DISK_SIZE -i DISK_NAME
```
  where DISK_SIZE is the capacity of the cartidge in megabytes (e.g., 65). DISK_NAME is the name of the raw device associated with the Bernoulli box. If the Bernoulli box is the first (or only) SCSI drive connected to the system, DISK_NAME will be /dev/rsd0a. If it's the second drive, DISK_NAME will be /dev/rsd1a.
  So, for example, to initialize a 65 MByte cartridge in SCSI drive 1, you'd type
```
disk -t iomega-65 -i /dev/rsd1a
```
  To initialize a 20 MByte cartridge in SCSI drive 0, you'd type
```
disk -t iomega-20 -i /dev/rsd0a
```
4. Workspace manager will put up an alert panel saying "Please insert disk in external drive N", where N is the SCSI unit number (0 for /dev/rsd0a, etc.)
5. Insert the cartridge in the Bernoulli box.
6. Initialization only takes a minute or so. When it's complete, type the following:
```
disk -e DISK_NAME
```
  Where DISK_NAME is the same as you used in the previous "disk" command. When the drive spins down and the light goes out, the procedure is complete. If you want Workspace Manager to mount the newly initialized cartridge, pull the cartridge out and re-insert it.
