Χαιρετώ τη λίστα.

Κατάφερα να σπείρω απόλυτο πανικό στο partition table ενός φίλου, με 
εξαιρετικά λίγες κινήσεις. Το πρόβλημά μου είναι ότι δεν ξέρω ακριβώς 
πού έγινε το κατόρθωμα. Αν μπορεί κανείς να μαντέψει, θα ήμουν 
ευγνώμων, ώστε να ξέρω να μη κάνω την ίδια βλακεία ξανά.

Ξεκινάμε με μηχάνημα με δύο partitions, WinXP NTFS και στα δύο. Σβήνουμε 
το δεύτερο, και στη θέση του δημιουργούμε τα εξής:

[0] /dev/hda5 ext3 /
[1] /dev/hda6 vfat /mnt/windows
[2] /dev/hda7 ext3 (!) /mnt/windows2
[3] /dev/hda8 swap

Όλα αυτά με τον installer του RedHat8.0. Τελειώνουμε την εγκατάσταση, 
και τότε συνειδητοποιούμε ότι κατά λάθος το /dev/hda7 είναι ext3fs και 
όχι vfat όπως θέλαμε.

Δεν κωλώνουμε, umount τα πάντα εκτός από το /, sync και mkfs.vfat 
/dev/hda7. Αλλαγές στο /etc/fstab, και μετά mount + read/write σε όλα 
τα partitions. Όνειρο.

(το λάθος) Reboot σε WinXP. Δεν βλέπουν το /dev/hda7. Το σβήνω από τον 
disk manager και το ξαναφτιάχνω.

(snip gory details)

Επόμενος τόνος: WinXP δεν bootάρουν καθόλου (BSOD), linux bootάρει μια 
χαρά. Από το linux μπορώ να διαβάσω τo NTFS partition των XP. Όλα τα 
ψιλά (/dev/hda6+ έχουν διαλυθεί και είναι unreadable). To (c)fdisk δεν 
μπορεί να κάνει list τα partitions, δίνοντας "Unable to seek on 
/dev/hda". Ένα fdisk -l /dev/hda* δίνει τα αποτελέσματα που έχω 
επισυνάψει.

Πού χάλασε η σούπα;
