- PROBLEM: We had a customer who was trying to use a Swift ST1126A IDE
- drive with ELS II v2.15. He had the new drivers for IDE
- drives. It wouldn't allow him to COMPSURF the drive. The
- drive had 1072 cylinders x 7 heads x 29 sectors per track.
- There is a drive type in setup for this. He had tried Disk
- Manager-N without success. He had also tried it on several
- different machines.
-
- COMMENTS: These are some problems with IDE drives:
-
- 1) The fact that some of them have to be user defined is a
- problem. Novell at this point does not fully support
- user defined drives.
-
- 2) They cannot be low level formatted. Do not low level
- format these drives with NetWare utilities.
-
- 3) ECC format (the number of bits that are used for error
- correction) is switchable on the drive so you must
- match the setting on the drive with the disk controller
- ECC setting.
-
- 4) When chaining IDE drives together, the first drive is
- the "master" drive and all others are "slave" drives.
- This IDE specification makes the "slave" drives totally
- dependent on the "master" drive for commands. Because
- of this drive protocol, you cannot mirror IDE drives.
- You are forced to duplex them.
-
- NOTE: See IDE.TXT on NetWire library 12 for a detailed
- explanation of all the support issues regarding IDE drives.
