Reproduced on two different USB sticks, therefore seems to be a real bug,
and not just a temporary flaw.
Working on Haiku revision 33109 (R1/alpha1) in VMWare Player 6.5 under
Windows XP. USB sticks are: Kingston 4GB, SanDisk Cruiser Micro 2GB, both
are formatted in FAT.
The problem is as follows:
1. Get the current Haiku code from the repository :)[[BR]]
2. Zip it using Zip-o-Matic.[[BR]]
3. You'll receive a file with size of approximately 236 MB.[[BR]]
4. Stick in the USB disk-on-key and allow the Haiku to discover it.[[BR]]
5. Mount it in read-write mode (since you want to copy the file on
it).[[BR]]
6. Start copying the file. I copied to the root folder of the disk.[[BR]]
7. Earlier or later, a KDL screen jumps in. It happens at about 186 MB
copied.
Smaller files are copied without any problem.
I tried to workaround the problem using
{{{
dd if=haiku.zip of=/usb_stick/haiku.zip ifb=8192 ofb=8192
}}}
- but it took A LOT of time and resulted in the same error.
Syslog complains about SCSI driver (see attached syslog.png file).
Some additional info is attached also.
