I can't mount my Iomega Zip 100 drive under SuSE 8.0. I can get linux to recognize the zip drive but not to mount it. "Mount" tells me that it detects a bogus logical sector size and that it is unable to find a valid FAT filesystem, yet I am using zip disks that work fine under Win98, and to which I have written files. Details follow. This is a parallel device, one of the later Iomega models that uses the imm driver, not ppa. I have the drive attached to parport0, and an HP printer attached to parport1. The drive works under Win98, and it contains a disk to which I have just written some short files. /etc/modules.conf contains the line: options parport_pc io=0x378,0xffa8 irq=none,none The directory /mnt/zip exists. The file /etc/fstab contains the line: /dev/sda /mnt/zip vfat noauto,user,owner 0 0 I first issue the command "insmod imm", which causes the drive to spin, and the following informaton is printed to /var/log/messages: imm: Version 2.05 (for Linux 2.4.0) imm: Found device at ID 6, Attempting to use EPP 32 bit imm: Communication established at 0x378 with ID 6 using EPP 32 bit scsi1 : Iomega VPI2 (imm) interface Vendor: IOMEGA Model: ZIP 100 Rev: P.04 Type: Direct-Access ANSI SCSI revision: 02 Attached scsi removable disk sda at scsi1, channel 0, id 6, lun 0 SCSI device sda: 196608 512-byte hdwr sectors (101 MB) sda: Write Protect is off sda: sda4 When I issue the command "fdisk -l", it returns the following information: linux:/home/blackdog # fdisk -l Disk /dev/sda: 64 heads, 32 sectors, 96 cylinders Units = cylinders of 2048 * 512 bytes Device Boot Start End Blocks Id System /dev/sda4 * 1 96 98288 6 FAT16 Disk /dev/hda: [...hda information] Disk /dev/hdb: [...hdb information] When I issue the command "cat /proc/scsi/scsi", it returns the following information: Attached devices: Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: HP Model: CD-Writer+ 9900j Rev: 1.30 Type: CD-ROM ANSI SCSI revision: 02 Host: scsi1 Channel: 00 Id: 06 Lun: 00 Vendor: IOMEGA Model: ZIP 100 Rev: P.04 Type: Direct-Access ANSI SCSI revision: 02 Now comes my problem: when I type "mount /mnt/zip" I get: mount: wrong fs type, bad option, bad superblock on /dev/sda, or too many mounted file systems and I get the following info written to /var/log/messages: Jul 19 21:58:12 linux kernel: FAT: bogus logical sector size 8293 Jul 19 21:58:12 linux kernel: VFS: Can't find a valid FAT filesystem on dev 08:00. If I type "mount -t vfat /dev/sda /mnt/zip" I get the same response. I have tried to mount various zip disks, all of which I've tested on Win98, and I get this symptom every time. I'm stumped. Please help!

You probably need to mount sda4, not sda.

Here is what I get: linux:/home/blackdog # mount -t vfat /dev/sda4 /mnt/zip mount: special device /dev/sda4 does not exist By the way, there are no contents whatever in /dev/scsi.

Hm, haven't we been there already? Anyway, try this: mknod /dev/sda4 b 0 4 Then try the same mount command again.

Thanks very much for your posts here and for your correspondence; I have the drive working now. I noticed that /dev/scsi was not populated with any files, and so I ran scsidev, followed by the mknod command that you suggest. Now it works fine, even after rebooting.
