USB HD blues

Hi guys, I'm wondering if someone could please shed some light on this issue. I recently bought an 80GB portable USB1.1/2.0 HD. It currently has the following partitions:
/dev/sda1 -- ext3 -- 47.5 GiB
/dev/sda2 -- FAT32 -- 27.5 GiB

I'm running Slackware 9.1 and have compiled the kernel (2.4.22) to have built-in USB2.0 and USB storage support (not using modules). I've disabled hotplug since I found it segfaulting a lot.

The partitions show up with [fdisk -l]. After I mount them with:
[mount -t ext3 /dev/sda1 /mnt/pub]
[mount -t vfat /dev/sda2 /mnt/winxp],

I can properly see the files on the FAT32 partition. However, when I try to copy some audio files from the FAT32 partition to the ext3 partition, the terminal freezes (both Ctrl-C and Ctrl-Z have no effect).

Eventually it says that it can't read from a sector or inode or something like that (the drive is nearly brand new so I doubt that). The light on the drive goes red, the drive "dies" and the partitions disappear from [fdisk -l].

Here's the actual error message:
usb-storage: host_reset() requested but not implemented
EXT3-fs error (device sd(8,1)): ext3_get_inode_loc: unable to read inode block - inode=2, block=6

I'm wondering if I'm doing something horribly and obviously wrong :/ Please help, I'd rather not have to return the drive because I can't get it to work properly...

My wild guess would be that the usb drivers, hardware and cable are not able to handle the load you are putting on them. If the files that you are copying are large and this problem appears for large files but not for small files, that would tend to confirm my guess.

can you write at all to the ext3 partition or is just when you try to copy from the fat32 partition?

you should try run fsck on the ext3 partition. Look at
man fsck
for the details and options.

It died when I try to play mp3s directly off the FAT32 partition...

I can't access either partition for any extended amount of time before both are unaccessable due to the disk fubaring...

However, I downloaded Knoppix 3.3 the other day and booted it up... while the drive is slow (I'm guessing it's using USB1.1 instead of 2.0), it has no problems reading from the drive... the kernel version is 2.4.22-xfs...

Anyway, now that I'm convinced it works at least for some Linux distros, I'll be patient and wait for kernel 2.6.0 before trying it again in Slackware (or maybe even ditch Slackware and move to Debian, although that's painful)... thanks for the help though!
