Fastlane Z3 checksum errors

[jlariv8957]

Hi,

I have the following config:
A3000/A3640(25mhz)/A2065/Picasso2+/Buster 11/FastlaneZ3 (56mb ram)/4,3Gb SCSI IBM hard disk

I have the following problem:
When I use my amiga after a certain time (don't know how exactly) i have some checksum errors on my boot disk
I use synchronous mode (10mbs), the cable seems to be OK, original cable from fastlane.

I thought it was a overheating problem but the 68040 have a very good fan: don't seem too hot, when i former had some overheating problems the errors disseapeared as machine getting cold but it is no more the case, i have the same problem when i use the disk with Winuae.

If it is a overheating problem i don't know what is overheating.

Should i use slow cable mode ??

Is there a way to repair checksum errors ? i tryed Disksalv but error remains.

Thanks

The disk is on the Fastlane card (i buyed it to have a reliable SCSI card because my a3000 & A3640 doesn't run properly)

I think there is no problem with scsi termination: i have one device witch is terminated.

I've seen somewhere that it is possible to "terminate" fastlane, does it have any interest ?

Thanks
