Έλεγχος σκληρού δίσκου Hardware

[matthew]

θέλω να ρωτήσω αν το 39 στους βαθμούς κελσίου που αναφέρει είναι η πιθανή αιτία του προβλήματος

39 βαθμοί είναι λογική θερμοκρασία για δίσκο. Εμένα πέρυσι το καλοκαίρι, πριν καθαρίσω το λάπτοπ, ο δεύτερος δίσκος που ανέφερα πιο πάνω έφτανε μέχρι 55 βαθμούς! Ο πρώτος δίσκος λόγω της θέσης του στο λάπτοπ πιάνει 4-5 βαθμούς χαμηλότερες θερμοκρασίες. Τώρα το έχω σε βάση ψύξης με ανεμιστήρα & οι θερμοκρασίες είναι σε ανεκτά όρια.

[nickaraxnos]

Οπότε να φανταστώ πως υπάρχει μεγάλη περίπτωση να παγώματα να οφείλονται στο μετασχηματιστή;

[matthew]

Χωρίς το τροφοδοτικό συνδεμένο, με τη μπαταρία μόνο δηλαδή, έχεις & εκεί παγώματα στην οθόνη; Είπες σε προηγούμενο ποστ ότι παρουσιάστηκε τις τελευταίες μέρες. Ίσως είναι θέμα driver της κάρτας γραφικών, βλέπω στην υπογραφή σου ότι έχεις τον ανοιχτό οδηγό (nouveau). Καλύτερα να ανοίξεις νέο θέμα στην κατηγορία με τις κάρτες γραφικών.

Εκτός από το CLI, πως το ενεργοποιώ από το GUI? Το εγκατέστησα (στο laptop), αλλά στο μενού δεν το βρίσκω.

Είχα από παλιά το Applications -> Accessories -> Disks, το οποίο έχει Home page το https://wiki.gnome.org/Design/Apps/Disks. Αυτό είναι?

Να και οι τιμές από το laptop:

Σχεδόν όλες είναι πάνω από το WORST. Δε καταλαβαίνω, είναι για πέταμα ο δίσκος?

Όχι, μια χαρά είναι ο δίσκος σου.

[Learner]

Σχεδόν όλες είναι πάνω από το WORST. Δε καταλαβαίνω, είναι για πέταμα ο δίσκος?

Όχι. Οι τιμές είναι raw values και δεν μεταφράζονται έτσι, απλά κοιτώντας τα νούμερα. Πολλές τιμές είναι HDD/SSD vendor specific , οπότε αναλόγως την μάρκα και το μοντέλο ίσως έχουν άλλη σημασία.

Οι μόνες (ίσως) ανησυχητικές να είναι αυτές

[bobptz]

Αν έχεις άλλο καλώδιο (πιο καινούριο) , δοκίμασε και αυτό.

Οι τιμές είναι από ένα laptop σχετικά καινούριο, το αγόρασα το Σεπτέμβριο. Δε μπορώ να αλλάξω τίποτα εκτός από το HDD.

[Learner]

Δε μπορώ να αλλάξω τίποτα εκτός από το HDD.

Ε τότε όχι μην αλλάξεις HDD. Τουλάχιστον όχι ακόμη. Πάντως για καινούριο HDD οι τιμές αυτές (εμένα) δεν μου κάθονται καλά.
Για παράδειγμα αυτές είναι οι δικές μου τιμές, από δίσκο σχεδόν 2 ετών

Μήπως έχεις το Laptop σε χώρο με υγρασία ; Μήπως κάνεις εκτεταμένη χρήση Windows ;

Ο χρήσης Learner προειδοποιεί: Η εκτεταμένη χρήση Windows βλάπτει σοβαρά τον δίσκο
Πέρα απ' την πλάκα, έχε το νου σου στον δίσκο, δηλαδή πως ; αποθήκευσε τις τιμές αυτές σε ένα αρχείο .txt και μετά από 1 μήνα τρέξε πάλι την εντολή και κάνε μια σύγκριση να δεις αν ανέβηκαν.

[bobptz]

Μήπως έχεις το Laptop σε χώρο με υγρασία ; Μήπως κάνεις εκτεταμένη χρήση Windows ;

Στο σπίτι μου αυτή τη στιγμή έχω σχετική υγρασία 60%. Δε νομίζω αυτό να είναι πρόβλημα. Το laptop έχει dual boot με windows7, αλλά μέχρι τώρα τα χρησιμοποιούσα λιγότερο.

Θα ελέγξω πάλι σε ένα μήνα. Τι να πω....

[qsd330]

μιας και πετυχα αυτο το θεμα και ανχωθηκα για λιγο.... να φανταστω οι δικοι μου hdd την εζεισαν την ζωη τους??
αλλα δεν καταλαβαινω κατι ακομα ο 320 ειναι σχετικα παλιος οκ ο 500 ειναι σχετικα νεος και διχνει να εχει περισσοτερεσ ωρες

μπορω να κανω reset στα stats? και ρωταω με τη λογικη οτι τα Seek_Error_Rate μπορει να προηλθαν απο κραδασμους ή καποια τυχαια γεγονοτα

CR = Command Register [HEX]
FR = Features Register [HEX]
SC = Sector Count Register [HEX]
SN = Sector Number Register [HEX]

Powered_Up_Time is measured from power on, and printed as
DDd+hh:mm:SS.sss where DD=days, hh=hours, mm=minutes,
SS=sec, and sss=millisec. It "wraps" after 49.710 days.

Error 842 occurred at disk power-on lifetime: 31034 hours (1293 days + 2 hours)
When the command that caused the error occurred, the device was active or idle.

After command completion occurred, registers were:
ER ST SC SN CL CH DH
-- -- -- -- -- -- --
