How Does Hot Swap Work with MPC3000 and MPC60?

I am wondering how hot swap drives/readers actually work, correctly, with the MPC3000 and MPC60.

For example, if you are in the Main Screen (or a disk load/save screen) and swap CF cards, do the contents of the newly inserted card automatically show up in the disk load and save screens, and does it automatically work correctly with disk operations on the newly inserted card?

Or, do you have to go into Make SCSI Device Active option, and make the SCSI ID for the CF reader active, or make a different SCSI ID active and then the CF reader ID active again, before the newly inserted card contents are visible and it will operate correctly with it?

Just wondering what the correct hot swap operation/procedure is with these MPCs, and also whether 3.50 works differently to 3.11 with hot swapping in the MPC3000.

hmm I dont know since I dont have one.. however my guess is probably you would need to go back to main screen and then go back into disk again? to refresh the page?

that would be my guess.. are you getting a hot swap reader?

I didn't bother attempting to go down the cf reader road on my 60 simply because of the ram limitations compared to the amount the machine can allocate on a drive.

Yes, I have a SATA-CF reader I am testing at the moment with a SCSI-SATA bridge, along with a few different ATAPI-CF readers with Acard SCSI-ATAPI bridges, in both an MPC3000 (3.11) and MPC60.

I am trying a few different currently available ATAPI-CF readers at the moment, to see what works, and thought I would order in a SATA-CF reader from one supplier as well, along with a SCSI-SATA bridge, just in case it worked.

The PATA readers are a PITA, the SATA reader seems like it might work well.


Just wondering how hot swap is supposed to work, 100% correctly, in these MPCs, so I have a baseline to compare my test results to.


The MPC60 RAM vs CF card capacity comparison, or the price, isn't really an issue for me (to an extent, a $700+NDA Zip-emulating industrial CF reader is too much even for me), I just want it to provide reliable and compatible hot swap transfer between MPCs and computer, between different MPCs, etc.

I'm using MPC3000 / Vailixi 3.50 and IDE CF Drive with Acard AEC-7720UW Ultra SCSI-to-IDE Bridge. Don't know how it behaves under OS 3.11 as I upgraded to Vailixi before I installed the CF drive. I can answer how it behaves under Vailixi if that will be any help for you.

It doesn't show automatically for me nor it works correctly immediately after swap.

To show the files properly this is what I have to do. Let's suppose that I loaded some files from let's call it a "Card A" before, and need to swap for, lets call it a "Card B". I insert the "Card B", go to DISK/LOAD screen. However the screen shows the files as they appeared in the "Card A" even it is not in the drive any longer.

What I have to do is to load some random "file" from the screen which is left over from the "Card A", of course "Card A" is not in the drive any more so the machine will show the error message that the disk is not inserted blah blah blah blah so I exit and return to DISK/LOAD and from this moment a new files from "Card B" are shown properly and I can load them correctly.

Or I can repeat the same process, but instead of loading some non-existent "files" which remained from the "Card A" what I have to do is to choose another partition of the disk from <Select disk> option, let's say from partition A to partition B. After that, again machine will show the classic error message that disk is not inserted blah blah blah blah but when I return back to DISK/LOAD screen, files from "Card B" are shown properly and can be read without any problem.

Which one?
Delock? Addionics Pro?

It's Delock once. But what's interesting that the bridge I'm using is 7720UW one and not 7720U everyone has. I read everywhere that 7720UW won't work, but it works as well. I suppose it just has to have the right FW.

I have Valixi OS too.
I have an external hot swappable Spyrus card reader. The way it works is:
After putting in the new card, all you have to do is go to the disk screen and change partitions, that way it reads again the contents and refreshes the screen with the new content. No need to go to the "make active" scsi screen...

Cheers,
Carlos

Which firmware are you using?

I have no clue, I received it as a part of kit and sticker with FW version which usually sits on the chip has been peeled down. But I found it interesting that 7720UW works as well, but of course it has to has the right FW.. But I don't expect U and UW version to be any different except the connector. Maybe the same FW which works in 7720U probably works with UW version as well? I really don't know and have no way to test it.
