Me neither, but the other report in this thread made it sound like there's some kind of complication.

You have a point.

I think a 20gb IDE 2.5" laptop drive is the best solution.

I like the compact flash approach since it's quiet and doesn't generate heat but a small laptop drive would probably work pretty well too.

Hello all!

Lovely forum you got here! No need to be misunderstood elsewhere anymore.

I have been thinking about the possiblilties to add a smart card reader as well. No one seems to have tried a dedicated internal scsi reader here right?

I found some links to some stuff that might work.

scsi - ide adapter

Floppy disk adapter

http://www.nightowlcamera.com/products/flashpath.html

Or the MicroTech PCD-25B or MicroTech PCD-47B SCSI Media Card Drive from SCI for samplers.

What do you think?


Edit: Changed last link

I have a Microtech PCMCIA to scsi reader/writer in my Kurzweil which is fitted into the floppy drive and it works well in the Kurz. My Ultras can all see it so I use it for sharing stuff across them.

I haven't considered putting it into an Ultra only because I didn't think there was a need. There is no reason why it shouldn't work though my only concern would be how much power it draws. This can be an issue for some loaded up Ultras.

Hmm interesting. I might check with scsiforsamplers.com and see if someone have succesfully used their readers for the emus. The power consumption might be a concern I?ll have to look it up.

I've noticed that most readers lately are usb, so a scsi internal reader should work by simply connecting it to where you would connect a Scsi HD. Is your internal HD scsi or IDE?

I?ll have to look that up actually.

Hi,

I've successfully used a Microtech SCSI CF unit (multi reader) in the Ultra - however, I ran into problems when also setting up the system to see a connected PC, and an external CD Rom and the Card Reader unit. I tried all manner of configurations (and I consider myself a SCSI veteran ) and could either get the card reader to work, but not both. PC would see sampler, but then hang when trying to access the SCSI bus. Just not reliable. I am not sure if this is to do with bugs in 4.7 either - I had the CF card (2G) EOS formatted to avoid the dual-master FAT conflict that I would expect to cause issues (i.e. having FAT32 on the SCSI that the PC can see at the same time as the Ultra - bad news as there is no multi master).

The unit also provides each reader as a separate SCSI ID - so PCMCIA, CF, Smartmedia (useless, as its max storage is 128MB).

It did take some time to get it right -as if the termination is wrong, or the ID's are set wrong or conflict, then the sample may see it but you get SCSI errors on writes, or it will appear as a ton of mirrored devices - confusing and conflicting the Ultra at the point of mounting the drive.

I compromised by making the unit an external mounted in the same unit as the CDROM (dual slot case).

I've also some non bootable IDE -CF adapters that I will try, an ACARD SCSI-IDE converter, plus various other drives and storage systems.

When I get a chance (job allowing, completing my analog synth mods etc etc ) I will write up a report showing what works and what does not.

I would be interested to hear if anyone else has an internal SCSI device connected inside the Ultra, along with an external PC to send samples.

I suspect the additional internal connection (which is in fact a SCSI split on the Ultra motherboard) is causing a termination impedance mismatch which is not possible to fix.

I can report that the Ultras will happily use a 2.5" IDE drive up to 137 GB (I used 120 GB) Samsung and WD drives no problem, and will use the full amount. The speed is good and these are near silent apart from tiny tiny tiny amounts of resonance when the heads track (hardly noticeable) - an excellent compromise and highly robust storage.

I have considered the 2.5" Drive mounting systems too - they convert say a 3.5" floppy slot into a removable 2.5" drive. This would be ideal for then say backing up the drive on a PC or Mac, but they are quite expensive ($120+).

Cheers,
Mark

ATAPI
For this reason SSDs (IDE) will not work in the EMu either.

ATAPI ... hmm... this seems to make sense.
With a IDE-SCSI bridge adapter you will get the (IDE) SSD working with the EMU.

The issues I see are:
- EOS cannot benefit from the high transfer rate of the SSD. The limit of the used SCSI-IC is 1,5 MB/s.
- EOS cannot handle HDs with more than 20GB in a reasonable way, with exception of EOS 4.70 using FAT32 as filesystem.
- A SSD with a IDE-SCSI bridge adapter is a very expensive solution in contrast to the SCSI CF-cardreader solutions SCM PCD-50B, PCD-47 or PCD-60.

Guys i have come across an issue with 'hotswapping' with the SCSI/IDE bridge. This is where you take the CF card out and change it and then press 'mount'. Anyway what i have discovered is that the Sandisk Extreme IV will not swap whereas the Sandisk Ultra 8gb (slightly slower) CF card will hotswap. Anyone else come across this ?
