IDE drive now freed from case and in scsi rack

Excellent service. Fast and efficient. Will definitely use again!!

Same as Colin:

I use this adapter with my AKAI S6000 sampler and a Barracuda 80GB hard drive and now my sampler is whisper quiet, performs better, and I have lots more storage for my samples and programs.

For anyone wishing to use this adapter with AKAI samplers.:

Problem and simple resolution:
The supplied firmware (v 3.88) led to random SCSI errors when writing sample data or deleting directories recursively but after some initial troubleshooting steps, I finally downgraded the firmware to version 3.7 which can be found on Acard's website. Since the firmware downgrade it has been perfectly reliable! I hope this helps someone out there.

I wholeheartedly recommend SPAN as a seller. Many thanks to Dean in particular who assisted me and was very reassuring and helpful.

Used this adapter to fix an old 68k Macintosh replacing defective original SCSI 240MB HD with new IDE 80GB HD. Adapter worked perfectly, new HD was immediately recognized by MacOS, formating to HDFS format was fully succesful. As a result the storage capacity of my old mac increased by more than 300 times !
Ordering was really easy, packaging was good and product has been timely delivered to me (Italy). Full satisfaction for a good price.
27/02/2008 | | GB Flag |
Fast Delivery and a great product. I used this use on an old 1986 Emu Emax Sampling Keyboard to convert from scsi storage to compact flash and it worked great. A recommended bridge to keep old technology alive.

I was testing this device for compatibility with a legacy automation product and it worked almost straight away. I have ordered more to carry out load testing with four devices.

Superb device! Used it with a legacy HP D-class Unix server to attach an IDE DVD burner, worked 100%!

Excellent service from Span too, hghley recommended.

in a fit of retro insanity, i got my creaky old Amiga 500 out of the loft, but very rapidly became irritated by the howl of the 17year old 52Mb scsi drive.
bought one of these SCSI to IDE cards,
bought a compact flash to IDE adapter,
bought a 4Gb compact flash card.

4Gb solid state hard disk on an Amiga 500, that is absolutley silent!! The OS saw it first time, partitioned, installed, booted! amazed!

as for the SCSI2IDE card - very impressed, truely operating system independent, plug in and go, does what it says on the tin etc. :)

thinking about getting another couple of these for my A1200 to move the Hard disk and DVD off of that nasty old IDE interface, but in an A1200's case, space is a premium.

I'm using a couple of these adapters with hardware MIDI samplers, and they have been excellent.
Even if you can find a decent capacity SCSI drive for a sampler, they are generally much noisier in operation than IDE drives.
I use one adaptor in an Akai S6000 to connect a Seagate Barracuda IDE drive, giving inexpensive and quiet storage.
The other adaptor I have connected to an IDE to Compact Flash card interface - this lets you attach a Compact Flash card to an IDE bus, to use as a solid-state hard drive (CF standard includes an ATA-compatible mode).
With the IDE to SCSI adaptor chained to the CF/IDE adaptor, I can use a 4GB Compact Flash card on the SCSI bus of my EMU sampler, for absolutely silent storage. Lovely.

I used this Adaptor to convert a SCSI output from a DAW in order to adapt an IDE dvd writer to backup data from the DAW. The Acard AEC-7720 fitted to the back of the DVD writer and the whole fitted into a SCSI box. The only drawback was that there was no power adaptor included, but some careful soldering made an adaptor out of an old power supply. Connecting up to the SCSI of the DAW, the Acard SCSI Adaptor was seen by the DAW, as was the IDE DVD writer, and communication between the writer and the DAW is no problem. Altogether a most impressive product, I see no reason why it should not work equally as well with an IDE hard Drive.

I purchased this card because I needed to build an external SCSI CDRW for use with one of my AKAI DPS16 DAWs. I used a very cheap Sony CDRW (£22) which has the advantage of being a little shorter than standard drives. This means with the Acard attached it is still no deeper than a regular drive. The included power supply splitter cable was a boon as it meant I had all the necessary cables and connectors. The only problem I had was mating the SCSI ID cable from the enclosure to the Acard - mainly because I did not know which part of the cable and the Acard connector were the commons. After a bit of trial and error the correct configuration was found. The only other slight niggle is the Acard slightly covers the CDRW audio connector but not enough to stop it being used; just makes it a tad awkward to fit that's all.

As for performance, the Sony burns and reads perfectly. I am only using SCSI II bus so the the Sony and Acard easily keep up with this. Overall I built myself ahigh speed external SCSI CDRW burner for less than £100. The Acard is excellent value for money IMHO and performs flawlessly.

"I have been using my Acard unit for a few weeks now, and felt that it deserved a review here.
It really is a remarkable piece of hardware.. easy to install, (just plug one end into an IDE drive, the other into your Scsi chain), NO DRIVERS required!!..(you may need to set the jumper for scsi drive assignment).. it is powering my Maxtor 120gig IDE with absolutely NO problem whatsoever, the system (a Dell server) detected the drive, spun it up, and declared itself happy!!. This hardware really doesn't need a manual.. and what a cost saving on IDE vs Scsi!!!!!, (Mine is utilised on an online server, where speed is optimal, and believe me.. it MOVES).
If there was one criticism, it is that the IDE and Scsi connectors are set to one side of the card, meaning it does protrude slightly over one side of the harddrive, and this may cause a few issues for the 5.25 drive bay users, but.. I would say unequivocally THIS IS A FINE CARD!."
