maxtransfer setting/ corrupt files

[acspo]

Hello group

i wanted to ask if there is any way to check the maxtransfer setting of the current hd?

Hd toolbox dont give me this values of the current Hd.


As for the corrupt files. Ill keep getting corrupted(not working games) with the dos-error # 219 (seek failure) on reading "gamename"

For the transfer of the (zipped) packages from pc to amiga 1200 I use the null modemcable and amiga explorer.

help :-)

thanks in advance

You need to click on 'Advanced Options' then 'Change' to view maxtransfer in HDToolbox

when i start HDtoolbox i cant select the advanced options for the current HD. I can edit the HD but there is no option for the maxtransfer..

Maybe there is a DOS command for this?

[Arnie]

Type in the new maxtransfer and press enter when done to save changes.

[Toni Wilen]

Remember that "Press enter" part of above post is required or new value is not saved!

[roy bates]

i think the setting you are looking for is : 0x1fe000 and press the enter key,not the return key.

and you should be able to save it.you can go back to see if its changed or not before saving it.

[acspo]

ah yes , found it. :-) Then the next question; can i change the maxtransfer without losing data? or do i need a new install of the workbench etc?

[thomas]

The correct setting is 0x1fe00 (255 times 512 bytes, converted to hexadecimal, preceded by 0x). And you can press Return, Enter or Tab, whichever you prefer. Just make sure that the cursor is active in the text field you want to confirm before you press the key.

The values for Mask and Maxtransfer can be changed without data loss. Be aware that you need to change the settings for each partition.

[acspo]

thanks for the replies,

But now i've got 2 different settings; roy mentioned 0x1fe000 and thomas mentioned 0x1fe00 . Which one is the one needed?

This is always confusing and pisses me off because you never understand what you have to type right since HD Toolbox or other similar tools use MORE zeroes than what is explained.

If I understand correctly, it's Thomas's solution. You can have leading zeroes (0x000001fe00) but not trailing zeroes (0x1fe0000000). Also Thomas is pretty much an authority on the matter so I'd always believe him :P

If this is wrong please clarify, this is just what makes mathematical sense to me, but the fact is that HD Toolbox uses more spaces than what is always said so it would be more helpful if people just write the full value instead of assuming people know about trailing and leading zeroes. Doing a search on the EAB just brings out a swarm of correct and incorrect values.

[johnim]

yes mate 2 zeros on the end thomas is correct

[acspo]

ok it's done, without problems. Thanks for the advice.

Sadly, i still got the;

dos-error # 219 (seek failure) !on reading "gamename"
with a lot of games.

Already downloaded and transferred the whd pakages from my pc to the amiga but those files still seems to be corrupt.

have somebody any other suggestion(s)?

Whatever you loaded on it with the wrong settings got corrupted . You need to copy them all again. No workaround.

[Arnie]

What is the size of the HardDrive?

[roy bates]

sorry mine was a typo,i meant two zeros

4gb compact flash

already did that, but still the same prob

[Arnie]

Are the whd packages in zip form?

The reason I ask is that some of the names are too long for the Amiga. Try shortening the names on the PC before transferring to the Amiga.

[acspo]

ok , going to try that 1

[acspo]

still got the dos error #219.
could it be that the files get corrupted through the way of transfer between pc and amiga?

I use a nullmodemcable and amiga explorer.

Hi acspo,

See http://www.wonkity.com/~wblock/a1200/a1200.html

"A1200 Hardware Frequently Asked Questions

Version 2.1 - Copyright © 1997 by Warren Block"

"Hard Drives"

"Q. What is MaxTransfer?

A. MaxTransfer is a value (set in HDToolBox) that limits how much data can be transferred to or from the hard drive at one time.
*

Q. Why is MaxTransfer needed? Shouldn't the drive move as much data at one time as possible?

A. Yes, it should, but some hard drives have arbitrary limits on how much data they can move at one time. On the Amiga, if you have problems transferring files of 128K or larger to or from the hard drive, this is a likely cause of the problem.
*

Q. I have have no idea what the MaxTransfer value should be for my drive. What value should I use?

A. For unknown drives, the maximum "safe" value is 0x0001FE00. Other (older) drives may require 0x0000FFFF or even 0x0000FE00. The sure test is to copy files larger than the MaxTransfer value to and from the drive, checking for corruption afterwards. Pictures work well for this, as corruption is easy to detect.
*
Q. Will this low MaxTransfer value slow down disk transfers?

A. Very little or not at all. Most disk transfers are smaller than 128K, and so this setting will not affect them. But don't take my word for it; use DiskSpeed and test it yourself. "


I hope this helps.

How sensitive is the Mask setting for hd-operations? What value is recommended eg. for BPPC scsi?

YEs, it could very well be.
Set your baud rate lower and try again. But if you have a CF device, your best solution (and MUCH faster) would be to put the CF card in your PC and copy the files over using WinUAE..

[rockape]

Hi Bamiga2002,

See the same Link I replied to ascpo.

Quote.

"Q. What is Mask?

A. Mask is a value (set in HDToolBox) that determines what area of memory can be used to buffer data transfers to or from the hard drive. Unless you have a good reason to change it, leave it at the default setting in HDToolBox."

Also Warren has posted a Link ref SCSI on the Amiga.

See http://www.wonkity.com/~wblock/SCSI/SCSIExamples.html


Hope this helps.

Doesn`t the transfer of packed files from PC to Amiga cause the loss of some file attributes ?

Yes i think so. But the weird thing is , that some games are ok by this way of transfer an some others not. Curse of enchantia is ok (large file) and defender of the crown (small file) gives me a dos error # 219

[acspo]

i am trying now beneath a steel sky (very large file) , it cost me an hour for transfer

and yes , CF card is much better and faster, i have ordered one at vesalia, but get no response from them.

[acspo]

grrrrr beneath a steel sky .......dos....errorrr.....ugh 219 aaaaah

[Arnie]

AmigaDos Error 219: Seek error
The AmigaDOS low level SEEK function has failed. This can be caused by an attempt to seek beyond the end of a file. It is usually a programmer error.

I have no idea what this means.

Same here..... altough getting crazy of it ...

[Bamiga2002]

@rockape
thx but what is the default setting of mask? I've changed it already to something else earlier.

[acspo]

I checked the zip files of the games that give the dos 219 error with unzip -t . unzip found no errors or corrupt files.

could it be the maxtransfer settings then? Thomas and several others on other forums say that 0x1fe00 as the recommended setting for the maxtransfer.

but the guys who michael mentioned gives totaly different settings;

So.. hm which setting will it be then?
and.. could it be the really the maxtransfer ? Because defender of the crown is just 758 kb and is also giving the dos219 error.

the Dos error mentioned that there is a seek failure in reading the "gamename". This gamename, for example futurewars is delphine and is located in the data folder.

do i have to edit something in the startup sequence? and if so how can i edit the startup sequence of a particular game?

[acspo]

hurray, thumps up for the Whdload support team (Wepl)

The problem is solved,

Finally i can enjoy the WHdinstalls

Thanks!

[Bamiga2002]

I kissed FFS goodbye a long time ago and switched to PFS3
Was tired of the goddamn validating...

[acspo]

well the positive part is that it was a good lesson in Amigalogy :-)

[thomas]

version dh2: is 39.27

So effectively you didn't change anything. If you'd use SFS then version would be 1.279.

The only corrective action I can see in the linked thread is "format al the partitions". This forces you to copy all files from another source again. You have been told that corrupted files have to be copied from a non-corrupted source. Probably you missed some.

[acspo]

well that is not entirely true. I did a full format and clean wb install before (with the old setting) also with new games from whddownload.com but at that time it didn't fixed the dos 219 error.
