Testing Biwin's 300X CompactFlash under Linux with the Delock 91694 FireWire to CompactFlash Reader

We wanted to test samples of 300X CompactFlash Cards from Biwin Semiconductor (HK) Company Limited. We decided to try using a different test platform than our typical iMac, and used a Xubuntu Linux desktop and the Delock 91694 CompactFlash FireWire 800 Reader. The great news is that the FireWire reader works just fine under Linux, and we were able to complete our benchmarks tests on these non-DLSR grade CompactFlash cards.

Our test machine is a Intel Core2 6300 @ 1.86GHz with 2GB RAM running Xubuntu 12.04.2 LTS. The reader was our Delock FireWire 800 to UDMA CompactFlash Drive Read-Writer 91694. We used the Linux application Disk Utility 3.0.2 to run the benchmarks. Here are the benchmarks for the cards, which are intended for general storage purposes.

Using Elan's U111-M SRAM and ATA Flash PCMCIA PC Card Drive with Unix-like Systems [first draft]

EverythingHerePlus.com announces a first draft of a document which outlines the use of the BSD and Linux compatible USB reader for PCMCIA PC Card SRAM and ATA Flash memory devices. While the draft isn't complete, experienced users will have no problems using the command line instructions to complete tasks.

Elan's U111-M PCMCIA PC Card reader for SRAM and ATA Flash memory devices is unique in that the reader itself brokers all the interfacing with the PC Card and presents itself to the host computer as a USB mass storage device. In addition to working on The Windows platforms, the device works with various versions of BSDs and Linux. Because of this, the U111-M allows users of Unix-like platforms to perform actions on these cards using common command line tools that usually require specialized and expensive software for The Windows. EverythingHerePlus hopes the document will be helpful to those wanting to deploy the U111-M with Unix-like systems.

U111-M Q&A, Compatibility with Mac OS X?

Question: Interested in purchasing the USB to PC card reader/writer but i want to make sure it is compatible with Apple computers and OS X.

Answer: Unfortunately, the U111-M currently doesn't work with Mac OS X as of this writing (January 2010). We've tested it extensively under Linux (Xubuntu Linux 9.04 (Jaunty Jackalope) amd64 edition), and even discovered viable work-around methods to get the U111M to work with OpenBSD (OpenBSD 4.6 beta i386 edition). However, the way the U111-M presents itself to Mac OS X precludes using even low level commands like diskutil and mount_msdos from Terminal. Mac OS X sees the U111M reader, and even the capacity of the inserted PCMCIA PC Card, but can't read the MBR of the PCMCIA PC Card, and hence is unable to treat it as a filesystem.

We're not sure if this is Elan or Apple's fault, but we're just as disappointed that it doesn't work with the Mac since we're Mac users too. If you have a spare Linux or OpenBSD machine, we can send you instructions for getting the U111M to work with those systems. U111-M also works with Windows 2000, XP 32, Vista 32.

If you have no need to read PCMCIA PC Card SRAM, and just need to read PCMCIA PC Card ATA Flash, we do have two different combinations of products that are well supported under Mac OS X.

PCM-CR-UEMUL03 MotionFlash32 USB 2.0 to 5 Slot Multi-Card Read-Writer 
in conjunction with the
ADP-ATA-CF CompactFlash Type I to 16-bit PC Card Type I/II Adapter for ATA Flash

or

PCM-CR-FW81ECF-02 CFFire800 Pro FireWire 800 to UDMA CompactFlash Drive Read-Writer 
in conjunction with the
ADP-ATA-CF CompactFlash Type I to 16-bit PC Card Type I/II Adapter for ATA Flash

Ordinarily we would recommend the FireWire solution because of overwhelming speed advantages, but ATA Flash PCMCIA PC Cards are so slow (PIO mode 4 -- max), that even USB 2.0 is more than adequate to read and write to them.

technology musings: U111-M USB to PC Card Read-Writer 1 Slot PCMCIA PC Card ATA Flash and SRAM Memory Cards

The U111-M is an external read-writer for PCMCIA PC Card SRAM, and ATA Flash memory cards. The U111-M works without additional software or drivers on supported operating systems, treating both SRAM and ATA Flash as standard removable USB mass storage devices. Used in concert with a Type II PC Card adapter, the U111M USB to PCMCIA Memory PC Card drive will work with a variety of consumer memory cards including CompactFlash and SD Cards. Used with desktop or notebooks computers, the U111-M USB to PC Card Read-Writer 1 Slot PCMCIA PC Card ATA Flash and SRAM makes copying files to and from PCMCIA PC Card SRAM and PCMCIA PC Card ATA Flash devices simple and straight forward without confusing software interfaces.

The U111-M comes with a USB 'Y' for use on rare systems with underpowered ports. Simply plug in the additional power only connection in order to provide necessary current. The U111M provides an inexpensive, hassle free solution to deploying legacy PCMCIA PC Card memory SRAM and ATA Flash cards on modern Linux and Windows computers with USB 1.1 or USB 2.0 ports.
