Problem copying files from PCMCIA Compact Flash

[UberFreak]

Hi

I'm having a strange problem copying files from CF - small files are copied Ok but bigger ones (usually above ~300Kb) get "stuck" - the copy dialog box is still displayed, but there's no progress.
At this point, if I remove the CF & re-insert it, copy will resume

This could happen several times on files over 1MB and is very frustrating!

The system is an A1200 with BPPC & BVision, ClassicWB3.9 + BB3 with WarpOS/PPCLibEmu/Warp3D installed.

Copying the same files between partitions on the HDD, or between RAM: and HDD is fine.
All partitions have MaxTransfer set to 1fe00 with SFS filesystem.
The CF in question is a Sandisk Ultra 4GB (30MB/s).

I have another A1200 with 030, on that system the problem does not exist.

Any would be greatly appreciated, I've ran out of things to try!


Thanks

Buffer size?

What happens if you do a shell copy?

[UberFreak]

No idea about buffer size, probably using the default.
I tried copying using Workbench & Dopus, not shell.
Will try that when I get home later

Thanks!

@FOL:

Same problem with shell.

Try another reader.

You mean CF->PCMCIA adapter?
I have 3 of them here, from different manufacturers, problem happens with all of them

EDIT:

Dont know if it helps, but when copying to RAM: instead of HDD, the problem happens less frequently.

Where did you format card? PC?

[UberFreak]

Yes, FAT formatted.

Try quick formatting it in the A1200.
Other than that, try a different CF Card.

[thomas]

If all that does not help, check which version of compactflash.device you use. There are two of them on Aminet (1.25 and 1.27). Try both (or try the other one if you already use one of them).

Hi

Ok, so far I tried:

- Changing compactflash.device to previous version (1.25)
- Formatting the CF on the Amiga

Neither fixed the problem.
Using a different CF is a problem, over the past 6 months I bought 5 different cards, the Sandisk is the only one that the Amiga recognizes.

Also, I now discovered that some of the files I did manage to copy are corrupt!
This explains why nearly all the demos I copied from CF dont work correctly

Thanks for all your suggestions so far!

[thomas]

Are you really sure that MaxTransfer is set correctly? In your first post you mention "all partitions", but what about the CF0 dosdriver?

The symptoms you describe point to a MaxTransfer problem.

Can you change max transfer of CF0?

He said it happens when copying to RAM: too.

[UberFreak]

I'll check if I can change MaxTransfer for the CF.

About the corruption, I have a hunch it only happens in files that get "stuck" & I need to remove & re-insert the card.

EDIT:

Can't change MaxTransfer through HDToolBox, it doesnt recognize the CF as an Amiga drive & wants me to "install" it.
Is there another way?

Ofcourse, silly me, Forgot about that, never needed to change it before, .

[UberFreak]

This is CF0's contents, as you can see there's no MaxTransfer setting.
I did try increasing the number of buffers & stack size, just to see if it has any effect (it doesnt).


FileSystem = l:fat95
Device = compactflash.device
Unit = 0
Flags = 0
LowCyl = 0
HighCyl = 0
Surfaces = 1
BlocksPerTrack = 1
BlockSize = 512
Buffers = 20
BufMemType = 1
BootPri = 0
Stacksize = 4096
Priority = 5
GlobVec = -1
DosType = 0x46415401

That doesn't necessarily mean you can't give it one. Try setting it to 0xffff (64k).

[UberFreak]

Ok, I added MaxTransfer of 0x0001fe00 & Mask of 0x7ffffffe (same as my HDD) to the CF0 mount file.
Still the same problem

When I tried lowering MaxTransfer to 0x0000fe00, the CF stopped showing up in WB & if I tried to access it via shell, it caused the window to stop responding & I needed to reboot.

EDIT:

MaxTransfer 0xffff behaves the same as 0x0001fe00
