FlexColor 4.7.1 – issues

Guide - Lisa - April 1, 2020

Last week I worked on a job that included using the Hasselblad H3D system and digital back.

This choice of digital capture system was based on a special promotion being offered by Hasselblad.

All most immediately we began experiencing problems with the camera during the evenings pre-light.

Since the rental company was closed I called my Hasselblad contact directly and he was kind enough to help us out during his commute home.

Our initial problems seemed to be solved by doing a global reset of the cameras firmware.

We got through the pre-light shooting to CF cards, and decided to get an early start the next day and see if shooting tethered was less problematic.

Almost immediately things went from bad to worse.

Once FlexColor V.4.7.1 was up and running we attached the H3D and instantly received an error message

stating that this version software was incompatible with the current camera firmware: “Do you wish to upgrade”

So we stepped through the firmware upgrade process which involved taking the whole camera apart as directed in the on-screen step by step process.

At the end of this process, which again resets all factory defaults, we were left with a camera that initially didn’t even want to turn on,

and then once turned on it refused to recognize the digital back and the back refused to acknowledge the camera body.

Again another round of problem solving that was resolved by plugging in the firewire from the computer to the camera and firing of 4-6 frames.

This method seemed to wake up both the digital back and the camera and allowed us to shoot to card once again.

Shooting tethered was not an option due to logistics.

As the morning progressed we next experienced problems with the brand new Extreme IV 8 gig CF cards.

after shooting to card , downloading and then reshooting to the same cards a few times the camera stopped writing to the CF card.

At first we thought it was a fluke. we switched out the bad card and added a new one into rotation. Two hours later the same thing.

I reformatted the card on the MAC then brought the card back to the camera and reformatted it two more times in the digital back before trying to shoot again.

This worked for all of 90 minutes when the same CF card produced the same issues.

In using the MAC disk utility I now found that the card had been corrupted and had bad write sectors.

This is what happens to low quality hard drives that over heat over long periods of time.

This is not something that should be happening to a brand new CF card.

We again added another CF card to the rotation and hours later the same result.

In all three different CF cards of sizes all became corrupted.

Calls to Hasselblad and teh rental company revealed that this is becoming a known issue impart due to the release of FlexColor 4.7.1 and the firmware upgrade.

Lexar Professional UDMA 300X CF card, and the Lexar Professional UDMA Firewire 800 reader.

Guide - Lisa - March 25, 2020

We get some great new toys to play with on occasion. The latest was sent to us by Lexar when they introduced the Lexar Professional UDMA 300X CF card, and the Lexar Professional UDMA Firewire 800 reader.

While most people specifically those renting digital cameras from rental companies find a Sandisk CF card included with the rental package. These new offerings from Lexar are well worth taking a look at.

Though Sandisk may have the strongest brand name in the flash memory market, they are not without their short comings in terms of the cards life span based on read/write capacity, and they also are the most expensive.

Lexar is actually a wholly owned subsidiary of Micron Technology, Inc. A company that like Sandisk manufactures there own flash memory chips.

For those not familiar with Micron Technology who markets there DRAM as Crucial memory and Flash memory as Lexar; Micron and Crucial memory has been the brand of choice for those building hard-core gaming computers and home computer enthusiasts that have been over-clocking their processors since the days of the Pentium 166.

The reason these computer users have chosen this brand of memory is because it takes the abuse, it runs fast, stays cool, and rarely to never causes system errors. This has also been my personal experience. I have been over clocking my PC’s including this sites servers for years using Crucial DRAM. And MAC users will find the Crucial memory is more stable and less expensive than other memory for Mac’s.

So during our last Digital Tech Workshop we put the Lexar Professional UDMA 300X CF card, and the Lexar Professional UDMA Firewire 800 reader to the test. I made every attempt to abuse it beyond what is was designed for.

This UDMA 300X card was tested in the Phase One P25+, P30+ backs, the Leaf AFi that was presented a few weeks ago by FotoCare and Leaf, and it was also used in the Canon 5d, MKII & MKII cameras.

After capturing to the card, and reformatting after every download, reformatting for every system change, including formatting it to both MAC and PC operating systems and using it to transfer video files; the UDMA 300X never had any problems.

The fact is when used in conjunction with the Lexar Professional UDMA Firewire 800 reader this is the fastest CF card data transfer combination that you can currently buy including any offering by Sandisk.

“..Blazing Fast!!” was what everyone that tried the card and card reader combination said.

Since we don’t have any speed test software the best we can offer is our opinion. But when compared to the Sandisk Ultra III that we have here. We saw data transfers taking seconds with the Lexar UDMA 300X as opposed to minutes with the Sandisk card.

Now as you can see below the Lexar option from a cost/performance stand point is by far the better option.

The above table represents the current comparable high performance CF card and CF card reader options from Lexar and Sandisk

Once again we see that checking out all of the options can not only save us money it can boost our workflow performance.

Guide - Lisa - March 20, 2020

The first thing I found when I plugged in the drive was that one of the Firewire 800 connectors on the back of the drive did not work.

The drive comes with 3 cables; Firewire 800 to 800 , Firewire 400 to 800 & USB 2.0. These fit the two Firewire 800 & single USB 2.0 connectors on the back of the drive. The drive also come with a power adapter which is needed when using the USB connection.

Once connected to the computer the drive heated up pretty quickly. Under a constant work load of transferring 9 gigs of data the heat sink got blazing hot. I took apart the drive to see if there was away to get things cooler. Once opened the real surprise came when I found that the heat sink is neither connected to the hard drive nor does it come in contact with any of the IC chips on the circuit board. In fact it seems that the sole purpose of the Heat sink is to act as a tray to hold the circuit board which slides into the heat sink via two narrow groves. the hard drive is then connected to the circuit board and faces out and away from the heat sink. So the hard drive is enclosed in a somewhat air tight container with no direct way to transfer the heat that is being generated by the hard drive. Though there are four mounting holes on the heat sink that could have easily allowed for connectivity to the hard drive no screws were attached. I found some spare mounting screws and attached the heat sink to the hard drive simply in hopes of extending the drives life span. While the drive was still running hot under a heavy load I have to believe that once the drive was actually attached to the heat sink at least some heat was being drawn away and the drive running just a bit cooler.

The heat sink displayed here is not connected to the hard drive. Which seems foolish considering the amount of heat being generated in this almost air tight container.

The sole propose for checking out this drive was for use as a way to transfer data between computers during our workshops. This drive would also be great as a small data storage device that is only connected for very short periods of time, or as a small back up drive that is used briefly and then gets stored away, or even as a drive to hand off to clients with the days images. This is not a drive that should be connected and running 24/7.

Pros: “Its’ pretty” like all things Mac, Small light weight, very fast, quiet. Seagate link.

cons: gets real hot real fast, poorly designed and lay out make the heat sink virtually useless since it is not directly connected to any part of the drive or circuit board. Not all connections worked on our test model. Pricey. the model tested listed on their web site for 259.99 plus tax and shipping. The Seagate drive alone can be found on the internet for as little as $148.00

Now for those of you that are not faint of heart, here is one method that will help to disperse some of that excess heat. — PLEASE NOTE THAT THIS PROCESS WILL VOID YOUR WARRANTY AND MAY CAUSE DAMAGE TO THE CIRCUIT BOARD. ——-

Ok, first we remove the two small screws on either side of the case, that are holding the back face plate covering the 1394b connectors.

Next remove the 4 screws holding the heat sink in place.

At this point the drive assembly should drop into the case and with a slight shake (over a soft surface) you should be able to remove the hold hard drive, circuit board and heart sink.

slide the heat sink off of the circuit board.

Now for the next steps you will have to make a decision; Leave the hard rive connected to the circuit board or remove it?

I chose to leave the drive connected since it added stability to the circuit board during the next steps.

In order to get the heat sink in closer contact with the hard drive we are going to attach the drive to the heat sink. The problem here is that the circuit board is wider that the inside area of the heat sink. In order to change this we will need to file down the circuit board so that the heat sink will completely wrap around the hard drive and not touch any portion of the circuit board.

To do this you will need a rasp or file preferably with a handle.

Now rather than drawing the file or rasp across the fiberglass printed circuit board, we will be sliding the edge of the circuit board accords the length of the file or rasp.

Before doing this I would suggest wrapping the drive circuit board combination in several layers of paper towel with only the surface to be worked on left exposed.

Before beginning, take notice of the tiny resisters attached to the edge of the circuit board. You will be filing right up to the point that you could knock one of these off; and they are on both sides of the board.

Set the edge of the circuit board on the file and with just a small amount of pressure begin drawing the board back and forth across the files surface. be extra careful to apply even pressure across the entire surface of the circuit boards edge so that you are not taking too much surface area off of the front and or back leading edges of the board while the center remains intact and becomes rounded.

You will be doing this to both side of the board, and you should be checking regularly to see which Side of the board needs more filing so that it will fit inside of the heat sink. Do not do all of the work on one side because it just won’t work.

This should take around 40 or more passes over the file, but check on the progress continuously to ensure that you don’t break any of the on board connections.

Now as your doing this and checking the progress you will notice that you are now exposing the top and bottom layer of copper on the circuit board. this is ok as long as you are applying constant even pressure as you are filing down the edges.

Once you have the desired width check the edge of the board for stay pieces of copper along the edges and clean them off either with the file or with emery paper.

Use dust off to completely remove any dust left behind. You may even wish to take the drive off of the circuit board to blow any dist out of there too.

Now its just a matter of reassembling the drive and putting it all back together.

Why hire Adam Gongwer?

Guide - Lisa - March 5, 2020

After I was born near the end of the Vietnam War, my mother divorced and moved us to Lexington, Ohio – south of Mansfield. While growing up in a small mid-Ohio town with only a few friends, I developed an interest in technology. I played chess on an A.I. computer board from Radio Shack and learned how to program “if-then” statements on a basic text editor. I quickly realized I could not write more than 10 lines of code before it would break and gave up a career in C programming. (See picture below for my early experiences on a TRS-80 computer at the local public library in 1983). In the early 90’s, I replaced a typewriter with a 386 PC for writing college papers in Cincinnati. Who can forget that unique noise from the DOT Matrix printer….I went from DOS to Win 3.1 during my two year stint in Bible College.

After moving back home to Lexington in the mid 90’s, I upgraded to Win 95 and began experimenting with HTML coding. The most annoying noise was a V.34 modem trying to connect to the internet.

View a clip of me predicting ‘the internet’ will be the “next big thing” in a 1996 newsclip (while on the Mansfield Reformatory Preservation Society board of directors).

Eventually, 56K modems took over the internet and more visually appealing websites were possible as I developed into a mature graphic artist. I built my own PC computer and soon realized that open-box display models at Microcenters were just as cheap. Working as a pre-press graphic designer for a few years, I was exposed to MAC and fell in love with the task bar placed at the top of the screen. After the turn of the century, I joined Ontario Police Department in 2003 and began assisting Chief Smith with I.T. responsibilities and evidence room management. I was added to the HNT team assisting with I.T. setup. I currently perform SRO duties which allows me to instruct in various classrooms on multiple topics including 7 years of DARE. I have participated in the following forensic classes: DOS, Internet Investigations 1, and Basic Computer Data Recovery.

At home, I soon found myself hosting other client’s websites and maintaining email pop accounts on a CentOS Unix server. Cpanel allowed for easy maintenance, upgrades, and installs. (For a full history of my graphic arts career from 1994 to the present, click here). I also represent citizens of Lexington as their councilman (cumulative total of 7 years dating back to the 90’s).

Ditching my old Blackberry for an android based phone, I could not convince the rest of my family to drop their iPhones. I co-exist in a world of Apple even though my inner heart has a Windows foundation. I even tried flirting with Ubuntu; however, I almost always chose Win 7 during the dual boot.

I also enjoy taking photos (portfolio) with my two Nikon cameras. I’m not anti-Canon but I do love Nikon and Nikkor lenses. I have been capturing HD video of my son’s high school band this year and posted his drum stick trick-throw on my Youtube channel.

I volunteer on the soundboard crew at my local church. Duties include Mixing, recording, mic setup, music and video choreography, and dual / split projectors.

I now look forward to a day where I can share this vast (almost expert) knowledge of computers with other law enforcement officers. My career goal now involves interviewing for and beginning an instructor position at OPOTA. After 8.5 years teaching various age groups in a school district as part of my SRO position, I attended “Instructional Skills” with Kerry Curtis in May 2016. That class has revolutionized my outlook on presenting material including utilizing a Student Centered Learning approach. Please review my computer history, instructional exposure, photography examples, and team work experiences or view a bullet point list of above.

In the meantime, if I could only get rid of all the Win 8.1 installations in the world and replace it with an updated “Win 7ish OS” look and feel…….

Adam began applying with OPOTA in July of 2016 while in his 14th year of law enforcement. Adam was hired by Ontario Police in 2003 after working as a Juvenile Corrections Officer. Adam has been a School Resource Officer for over 8 years with Ontario Local Schools, and taught DARE for 6 years. He has also been on the county-wide Hostage Negotiation Team since 2006. Adam received an Associates Degree in Criminal Justice from North Central State College. Adam currently holds the Secretary/Treasurer position on the board of directors for the Ohio School Resource Officers Association and assists with training new SRO’s. Adam specializes in assisting the Police Department with computer I.T. issues and Evidence Room management.
