Hi,

I have a Lindy usb external IDE enclosure (usb 2.0 version) with a Matrox
40 GB hard disk (7200 rpm) in it.

Q1: should the disk be master/slave both ?

It connects to a usb 1.0 (1.1 ?) port on the motherboard, Linux (red hat
7.3) se it fine - no need to load any extra modules.

I partitioned it (linux 83): 1 partition,

I formatted it,

I mount it, copy a couple of files onto it,

all is well.

However, when I try to do a LARGE cp (many files, and some large ones),
I get a lot of errors writing to the USB drive, and even some disk full
(when it is not) errors.

Then running fschk, throws up loads of problems with inodes, i_blocks,...

Q2: any one have any ideas ?

NB. currently checking the disk for bad blocks - none yet, it will be
finished in the morning.


I'm going to try copying all files through a shell script (using find *), to
see if having a little delay between each file copy helps ?

Q3: how should I really ensure that all the buffers are flushed to the
drive before I remove it ? I don't think umount is enough. Is adding a
sync enough ?

Thanks,
John.
