Slow pendrive upload
|

| Hi there,
I've got MoVo TX MP3 player - which is also usable as a pendrive.
I've compiled in kernel all required options (just like some How-To
says) and it's detected correctly.
Copying from pendrive to my hard drive is pretty fast, about 3-4MB/s
(USB 2.0), but uploading is much slower.
Strange thing is, that this "slow" speed is very significant - it's
32KB/s. Sometimes it's 256KB/s, but I see no rule for this.
It's horribly slow! I've tried it under Windows system, on the same
machine and the result of uploading to pendrive is about 3MB/s.
I've checked if Windows does or doesn't do this asynchronously, but it
doesn't. It's fully synchronized.
What can I do?
This is what dmesg says about my pendrive:
hda: ST340016A, ATA DISK drive
blk: queue c03af460, I/O limit 4095Mb (mask 0xffffffff)
hdc: HL-DT-ST DVDRAM GSA-4163B, ATAPI CD/DVD-ROM drive

ide1 at 0x170-0x177,0x376 on irq 15
hda: attached ide-disk driver.
hda: host protected area => 1
hda: 78165360 sectors (40021 MB) w/2048KiB Cache, CHS=4865/255/63,

| Deam it! dmesg output is wrong of course, this one is correct:

sda: Write Protect is off
sda: Mode Sense: 38 00 00 00
sda: assuming drive cache: write through

Which distro are you using? AFAIK, SuSE had this problem in 10.0.

My friend who uses SuSE also had such speeds.

Same.
