dos2unix did not help

Thank you blowtorch for the suggestion. I tried dos2unix on the .gz files, and it did produce smaller files. But they were still unacceptable to gunzip. I guess it would only take one "legitimate" occurance of the byte pair 0D0A in the .gz file to make the approach I am taking not work, because dos2unix would replace it with 0A (I think). I would want that to happen most of the time, but not if the original 0D0A were in the original good .gz file.

I appreciate your help, though. You provided information that I had already wanted to try, but I didn't know the name dos2unix.

Since I can extract a few of my original files from the corrupted .gz files, I will keep them around. At this point I think I need to learn more about how .gz files are organized, and about how gunzip works.

(My files contain several million newsfeed blurbs related to over 8,000 topics. They represent a form of current events history, so I really want them back. But, at the same time, there is no real rush. )

Thanks again for your suggestion.

oce

OCE(4)							   BSD Kernel Interfaces Manual 						    OCE(4)

NAME

     oce -- Device driver for Emulex OneConnect 10Gb network adapters

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel configuration file:

	   device pci
	   device oce

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   if_oce_load="YES"

DESCRIPTION

     Emulex OneConnect adapters come in various skews and with different combinations of NIC, FCoE and iSCSI functions.  The oce driver claims the
     NIC functions in all these adapters.

     The oce driver supports VLAN Hardware offload, TCP checksum offload, TCP segmentation offload (TSO), Large receive offload (LRO), Bonding,
     Jumbo frames (from 1500 - 9000), Multiple TX queues, Receive-Side Scaling (RSS) and MSI-X interrupts.

HARDWARE

     The oce driver supports the following network adapters:

     o	 Emulex BladeEngine 2
     o	 Emulex BladeEngine 3
     o	 Emulex Lancer

UPDATING FIRMWARE

     Adapter firmware updates are persistent.

     Firmware can be updated by following the steps below:

     1.   Copy the below code to a Makefile:

		KMOD=elxflash
		FIRMWS=imagename.ufi:elxflash
		.include <bsd.kmod.mk>

     2.   Replace imagename in above with UFI file name

     3.   Copy Makefile and UFI file to a directory

     4.   Execute make & copy generated elxflash.ko to /lib/modules

     5.   sysctl dev.oce.<if_id>.fw_upgrade=elxflash

     6.   Reboot the machine

     In case of issues with supplied UFI, flashing fails with one of the following errors.

     1.   "Invalid BE3 firmware image"
     2.   "Invalid Cookie. Firmware image corrupted ?"
     3.   "cmd to write to flash rom failed."

SUPPORT

     For general information and support, go to the Emulex website at: http://www.Emulex.com/ or E-Mail at freebsd-drivers@emulex.com.
