| Adtron SCSI Compact Flash drive? | |
| Posted by: Macdrone on 2013-10-19 14:07:32 I may have a cable for you, I'll look. | |
| Posted by: NJRoadfan on 2013-10-19 19:07:05 After digging on the other external drive I have, I found another 68000 friendly partition and SCSI driver program, Transoft SCSIDirector 3.1. | |
Posted by: Bunsen on 2013-10-20 06:52:05These would be perfect to fit into one of those 2.5" SCSI external "pocket" drives that were kicking around here recently.http://cgi.ebay.com/281188955190 - seller happyhairgirl Unrelated: I have some 3.5" SCSI to PCMCIA adapters here. Would anyone like to swap one of these 2.5" adapters for one of them? They're untested right now, but if anyone is interested, I will test with a PCMCIA-CF before shipping. PM please, so as not to derail this thread. | |
| Posted by: Paralel on 2013-10-20 09:50:29 Be forewarned, both Uni and I had to return those exact same units we bought from this seller because they were faulty. | |
| Posted by: Bunsen on 2013-10-20 10:02:25 Which, the 3.5" SCSI-PCMCIA, the 2.5" drive boxes, or the Adtron SCSI-CF? Mod note: everyone, please don't quote the post right behind you, unless it's to clarify what part exactly you're replying to, by quoting only that. In this house, we read down the page. | |
| Posted by: techknight on 2013-10-20 17:49:08 the SCSI boxes. I was following that thread, because i thought about tossing an adtron in one of those. | |
| Posted by: snuci on 2013-10-21 15:29:49 Well, it turns out the Adtron CANNOT do 16GB CF cards. Lido says "Cannot determin capacity" and then gives SCSI errors. I swapped in a 512MB card I had used before and then saw no problem. I guess bigger isn't always better 🙂 What is the largest those who have them has tried? | |
| Posted by: Paralel on 2013-10-21 16:04:19 Looks like 4 is the largest one yet, if I'm not mistaken, and it worked. All we need is 8 GB and we'll know what they are capable of. If no one else has an 8 to try, I can always pick one up locally to test, in the name of science. | |
| Posted by: NJRoadfan on 2013-10-21 17:55:44 I really need to get off my butt and test mine out. I could really use a 2.5" to 3.5" adapter though since tearing apart Powerbook 100 series isn't much fun at all. Plus I can test and see how it behaves in various desktop Macs and PCs.... and an Amiga. What was the ROM revision on the card that couldn't see the 16GB card? Its a strong possibility the unit will work with 8GB cards, but won't see anything above 8.4GB due to Int13h limits. | |
| Posted by: snuci on 2013-10-21 18:28:21 The firmware in mine is 1999 version 2.02a. I'm totally fine with 8GB or 4GB but I just want to be sure before purchasing. I will be trying to re-purpose the 16GB for an Amiga 1200 this weekend and give up my 4GB for one of these. I'd also like to put one of these in a NeXT Cube so either of the smaller sizes is fine but I just want to maximize the size and forget about it. Any testing you can do would be great. | |
| Posted by: Paralel on 2013-10-22 00:47:06 If someone can do it before me, great, if not, I'll do it. I just need to wait to get a new SCSI cable for my Powerbook since I retardedly managed to destroy the one I had. | |
| Posted by: olePigeon on 2013-10-26 12:16:39 I can't seem to get mine to work. I've put in some 2GB 133x CF cards in them. Lido says it can't recognize the size then gives me a BUS error and crashes. On my G4, HDT says the device isn't ready and won't let me erase it. :-/ | |
| Posted by: Macdrone on 2013-10-26 13:21:35 Which version of hard disk toolkit? I know 2.5 works. Did you try just one CF card in either slot? It's picky about CF cards. I had to erase mine in a digital camera before it would use what I had. Do your CF cards have lock switches on them? That will trick it. Some cables that plug into the card may or may not have the correct pin missing for the card and it may be plugged in backwards. If your putting it in a desktop you must have the 2.5 to 3.5 adapter that may also be your issue. It's not a power monster and may not play nice with the adapter. I hope I have given you some ideas you have not looked into. Good luck. | |
| Posted by: olePigeon on 2013-10-26 17:49:52 I tried just one card in 1 slot, 1 card in the other slot, and 2 cards in both slots. Same result in each case. I erased the CF cards using my ATA CF card adapter. I also tried partitioning them to under 1GB in size each, and still didn't work. Micronet reports that the carriage is empty, even when there's a card inserted. | |
| Posted by: Macdrone on 2013-10-26 18:48:26 Do you have a laptop to try it in? Again maybe the adapter doesn't agree with the adtron. | |
| Posted by: NJRoadfan on 2013-10-26 18:49:39 Finally did my testing. First off, this device does support 8GB CF cards. My Transend 8GB 133X CF card was recognized without a problem. I'll also add that it supports very small CF cards too as a Canon branded 8MB CF card worked without a problem. Connection to desktop machines was with a Cables-to-Go 2.5" to 3.5" SCSI adapter. What I did have a problem with is with host controllers. My 486's Adaptec AHA-2740W EISA card (40MB/sec WideSCSI with 50/68pin plugs) wouldn't see it at all, but I have had problems with that card seeing devices in the past. My PCI AHA-2920C card (10MB/sec fast SCSI) worked fine with it. Anyway this device is.... slow. Here is the native speed of the device running off of a Promise UltraTX2 ATA100 card as a baseline:  These speeds check out with Transend's data sheet. For comparison, here is the card running off of the onboard IDE ports, likely using PIO transfer mode (DMA disabled). This is very close to what I get running this CF card on an ISA bus controller:  The Adcom off of the Adaptec SCSI card:  OUCH. Performance in anything remotely modern with this device is going to be lousy. Good thing the only 2.5" SCSI devices out there are old and slow anyway. Its a good choice for old computers like Powerbooks though. Whats sad is the SCSI controller on the Adcom adapter supports 20MB/sec transfers, so the bottleneck is likely the firmware, ATA interface, or CPU. I would love to get a hold of one of the ACARD adapters or the Power Monster and see how they compare to this. I wouldn't be surprised if they are much faster. | |
| Posted by: techknight on 2013-10-26 20:13:39 186 CPU. probably the CPU. lol. However, that should make mmcmaster feel better, his SD adapter is faster. | |
| Posted by: NJRoadfan on 2013-10-26 20:22:17 I wouldn't be surprised if the CF Card was running in PIO Mode 0, a paltry 3.3MB/sec. I think this card was conservatively designed anyway given its target market of industrial machine use. I didn't check to see what speed the SCSI interface actually ran at. I wouldn't be surprised if it was the standard 5MB/sec SCSI-1 mode. Would be an interesting device to firmware hack to see if more speed can be coaxed out of it. | |
| Posted by: NJRoadfan on 2013-10-26 22:21:42 Apparently the Adcom is using something better than PIO0, here is the results from hooking up the CF card directly to an ISA controller in a 486. About 1MB/sec. Eck!  | |
| Posted by: olePigeon on 2013-10-26 23:26:47 Well, then I hope it's my adapter. I plugged it directly into my IIci bypassing the Adaptec card, and same issue. I'll try and find the same adapter njroadfan has. This is the one I have, by the way: http://www.cablesonline.com/25lapscsihar.html | |
