External USB drive very slow on first access

January 11, 2011 at 02:49:43
Specs: OpenSUSE Linux 11.1
The very first access to my Linux external drive is terribly time consuming.
The first access can occur at boot time - where booting then takes a number of minutes to complete.
It also occurs each time the drive is manually mounted. In this case a df -k or ls -l command may take upwards of a minute.
Further listings or dfs are instantanious - as you would expect.

The drive was working fine until a recent system hang - not sure what caused this to happen. But since then the drive has this annoying behaviour first time of asking.
Anyone have any idea why it could be so slow the very first time?
Thanks very much.

Have you tried running fsck on the drive to check for errors?

I haven't.
The drive seems to behave well once it is mounted.

'mount' shows:
/dev/sdd1 on /usb1 type vfat (rw,noexec,nosuid,nodev,gid=1000,umask=0002,utf8=true)

fsck /dev/sdd1 shows:
fsck 1.41.1 (01-Sep-2008)
dosfsck 2.11, 12 Mar 2005, FAT32, LFN
/dev/sdd1: 24436 files, 12058532/15254800 clusters

Nothing obvious there?
