Βγάζει σημαντικά προβλήματα με το σύστημα αρχείων. Θέλει μορφοποίηση ξανά (format) και δοκιμή.
Μπορεί το πρόβλημα αποσύνδεσης να προέρχεται από χαλασμένο σύστημα αρχείων.

Το πρόβλημα που αντιμετωπίζεις είναι ότι μέσω USB (ως εξωτερικός δίσκος USB) δεν έχεις πρόσβαση στις πληροφορίες S.M.A.R.T. που μπορούν να πουν αν υπάρχει πρόβλημα υλικού.

Αν μπορείς να ανοίξεις τον εξωτερικό σκληρό δίσκο και να τον βάλεις στο φορητό σου (ή να τον συνδέσεις ως SATA σε κάποιο υπολογιστή),
τότε με ένα LiveCD μπορείς να δεις τις πληροφορίες S.M.A.R.T. και αν υπάρχει πρόβλημα hardware.

Στο laptop 1 γιατι δεν εχει προβλημα αυτος ο σκληρος δισκος;
Μηπως φταινε οι θυρες USB του HP;
Αυτος πώς μπορω να το τσεκαρω;

Στο laptop 1 γιατι δεν εχει προβλημα αυτος ο σκληρος δισκος;
Μηπως φταινε οι θυρες USB του HP;
Αυτος πώς μπορω να το τσεκαρω;

Δεν μπορώ να σκεφτώ αυτή τη στιγμή. Αυτό που θέλεις να δεις (ή να googlάρεις) είναι
1. πως βλέπεις αν ο εξ. σκληρός λαμβάνει τόσο ρεύμα όσο χρειάζεται. Είναι πιθανό να μη φθάνει το ρεύμα.
Έχεις εκείνο το καλώδιο USB που χρησιμοποιεί δύο θύρες από το φορητό; Αν ναι, χρησιμοποίησέ το.
2. μπορεί να υπάρχει τεχνικό ζήτημα με τις θύρες USB. Δε γνωρίζω περισσότερα,
cat /proc/interrupts
μπορεί να δείξει κάποια πράγματα.

Ευχαριστω για τη βοηθεια.
1. Ρωτησα τον πωλητη και μου ειπε οτι σε λαπτοπ HP και Toshiba εμφανιζεται καποιες φορες χαμηλη ταση σε θυρες USB.
Για αυτο συνδεεται/αποσυνδεεται συνεχως.
Τωρα δοκιμασα στην αριστερη πλευρα την θυρα Combo eSATA/USB και παιζει κανονικα.
Αρα οι δυο θυρες αριστερα δουλευουν (μια απλη USB και μια Combo eSATA/USB) ενω οι δυο θυρες δεξια (απλες USB και οι δυο) δεν δουλευουν, πιθανοτατα λογω χαμηλης τασης.
2. Δεν καταλαβαινω το περιεχομενο του αρχειου.
Θα ψαξω αλλιως το θεμα.

Θα μπορούσες παρ' όλα αυτά να παραθέσεις εδώ τα περιεχόμενα του μέσα σε code tags, δηλ. έτσι:

Τι παρατηρειτε;

[2010]

Πηρα τηλεφωνο στην τεχνικη υποστηριξη HP και μου ειπαν οτι οι δυο δεξιες θυρες USB δεν ειναι ενσωματωμενες στη μητρικη οπως οι αριστερες.
Συνδεονται με αυτην μεσω ενος USB Connector και ενος Base Cable Kit, αρα μπορει να εχει χαλασει το καλωδιο συνδεσης με τη μητρικη.
Σκεφτομαι να το παω στο Service.
Δεν πιστευω να πουν τιποτα οταν δουν οτι δεν εχω Windows...
