Άργησα να απαντήσω γιατί έκανα αρκετές δοκιμές-ψάξιμο.
Ιδού το αποτέλεσμα της εντολής dmesg (την έδωσα σε debian-testing, το
ίδιο πρόβλημα όμως ισχύει και σε ubuntu-feisty), όπου πράγματι στο τέλος
αναφέρεται στο sda2 το οποίο έμφανίζει το πρόβλημα:

Έψαξα λίγο το hdparm και έβαλα στο /etc/hdparm.conf την ακόλουθη
καταχώρηση:
/dev/sda2 {
mult_sect_io = 16
write_cache = off
dma = on
}
Χωρίς να είμαι βέβαιος για την διαπίστωση, έχω την εντύπωση ότι πλέον ο
δίσκος αργεί λίγο περισσότερο να πέσει σε κατάσταση ύπνωσης ή αναμονής
ή ... (πως λέγεται, iddle?). Παρατηρώ (από τον ήχο και την ένταση του
φωτός στο λαμπάκι) ότι όταν ο δίσκος δεν είναι ενεργός κάνει 1-2
δευτερόλεπτα να ξαναπάρει μπροστά κάθε φορά που επιχειρώ πρόσβαση, και
τότε είναι που γίνεται το ext3 mounted ως read-only.
Χωρίς να γνωρίζω αν χρησιμεύουν, ιδού το αποτέλεσμα της εντολής hdparm
-Tt /dev/sda2:
iplaptop:~# hdparm -Tt /dev/sda2
/dev/sda2:
Timing cached reads: 694 MB in 2.01 seconds = 346.00 MB/sec
Timing buffered disk reads: 4 MB in 4.03 seconds = 1016.02 kB/sec
και της εντολής hdparm /dev/sda2:
iplaptop:~# hdparm /dev/sda2
/dev/sda2:
readonly = 0 (off)
readahead = 256 (on)
geometry = 30401/255/63, sectors = 68372640, start = 420019425
και της εντολής sdparm -a /dev/sda2:
iplaptop:~# sdparm -a /dev/sda2
/dev/sda2: Seagate FreeAgentDesktop 100D
