- There are a number of possibilities for the source of the problem.
- Perhaps people on this list can help me out. Those drives are
- sufficiently inexpensive that if we weren't really tight on cash right
- now, we'd just buy one and figure it out from here, but we just can't
- do that right now.
-
- There are two different ways that a Mac disk can have an HFS
- filesystem on it. The original way, which was used on the first SCSI
- hard drives, and is still used by floppies and HFS CD-ROMs is to just
- plop the filesystem down at the beginning of the disk. However, as
- disks got larger, it made sense to partition them, so some disks have
- partition tables at the beginning. In addition to these two issues is
- the question of just how large the underlying block size is on the
- disk.
-
- The trouble is that currently, Executor does not support disks that
- have partition tables that have block sizes > 512 bytes/sector.
- Writing the support for such drives is really fairly easy, the problem
- is we have no such critters in house. It may be that the Zip drives
- fall into this category. Is there anyone out there who can dump the
- first 2048 characters of the drive into a file and then drop the file
- into ftp://ftp.ardi.com/incoming? Furthermore, does anyone know with
- certainty the block size of Zip drives?
-
- If I get a dump of the first 2k characters and also find out that the
- block size is indeed > 512, then I'll modify Executor to theoretically
- support larger block sizes and then have someone test it on a Zip
- drive. If I can't get answers to those questions I can write some
- special code that can be run on the Zip drive that will answer the
- questions for me. The latter takes more of my time, so I'd like to
- wait a few days to see if anyone has answers to the former.
-
- We very much want to support both the Zip drives and SyQuest's new 130
- MB drive. We almost bought one of the SyQuests last night, but the
- cost of an unexpected root canal held us back. Once 2.0 is shipping
- we shouldn't be quite so broke.
