elenco attributi codice A0 file 1A è danneggiata

Question

Buon giorno a tutti.

Sto avendo delle difficoltà con un hdd esterno che a un certo punto mi ha smesso di funzionare. Quando ho provato ad effettuare un chkdsk mi ha restituito questi due errori:

La voce dell'elenco attributi con codice A0 nel file 1A è danneggiata

La voce dell'elenco attributi con codice B0 nel file 1A è danneggiata

Cosa posso fare per evitare di perdere dati contenuti nell'hdd? Se faccio una scansione utilizzando chkdsk /F /R rischio di danneggiare file?

Ciao Elia Romano

Probabilmente un file si è danneggiato, ma chkdsk non peggiorerà la situazione, anzi tenterà di recuperarlo.

Per il futuro, ti consiglio di eseguire un backup completo e frequente dei tuoi dati.

Hello Elia. The errors you're experiencing "File 1A has an attribute list entry with code A0/B0 that is corrupted" is an indication of file system metadata damage to the NTFS file system in particular the Master File Table. The attribute list entries manage extended file data, and the corruption of this data can cause the inability to access files or folders in the NTFS file system. Executing chkdsk /F /R will probably attempt to repair - but the repair processes are not recalled, but it can and may also delete elements of broken and thereby unrecoverable NTFS metadata, or rather - may not be able to repair the metadata corruption so badly that anything recovered is not worth the hassle.

Without a concern of data loss the best thing to do in this situation is to recover files before running and hopefully repairing - while ensuring data is exported to a capable storage solution from the instance drive. Next is to employ read-only recovery solutions like TestDisk, Recuva and so on; and it is worth a thought to mount the drive in Linux and utilize only read-only access as many Linux distributions are able to access NTFS Volumes without writing to them directly.

Once you get copies of important data, you can run chkdsk /F /R to repair anarly all of NTFS File System data. If the drive has issues retaining stability of file, you may have to consider using NTFS recovery, while using sophisticated scanning solution like SpinRite and HDAT2, which are able to recover data from physical location sectors, and again would be reluctant to provide a fix to NTFS structure issues.

Best regards,
