hdb1 access suddenly EXTREMELY slow...
symptom: read access to my home directory has dropped to internet access speeds (VERY slow, i'm not networked). also, about every four or five times i boot the machine, the start up hangs at "mounting local filesystems". when i reboot, it complains the disks were not cleanly unmounted, checks them all (i have 3, all except one is working properly). when it checks my hdb1, it takes 1 and a half hours! it finds it to be fine and boots successfully. the other two disks check out at normal speeds...a few seconds.
my stats: mandrake 9.1, p4 1.5gz, 512 RAM, 3 hard drives all 7200 rpm, ide, 40 gb.
my fstab (hdb1 is the problem):
/dev/hda1 / ext3 defaults 1 1
none /dev/pts devpts mode=0620 0 0
/dev/hdb1 /home ext2 nosuid,defaults 1 2
/dev/hda5 /mnt/backup ext3 rw,suid,dev,auto,user,async 1 2
/dev/scd0 /mnt/cdrecorder auto rw,noauto,user,exec 0 0
/dev/hdd /mnt/cdrom auto ro,noauto,user,exec 0 0
none /mnt/floppy supermount dev=/dev/fd0,fs=auto,--,iocharset=iso8859-1,sync,codepage=850,umask=0 0 0
/dev/hdc5 /mnt/openspace ext2 rw,suid,nodev,noexec,auto,user,async 1 2
none /proc proc defaults 0 0
oh please oh please any ideas out there? grinning but desperate.
