How long for Analysis and what are read errors?

#1 Postby Frazel » 04 Apr 2012, 05:15

Hi

Thanks for creating this utility and making it available for download.

I have a 2Tb USB HDD that windows no longer recognises (tried in a range of WinXP machines both installed internally (SCSI) and in USB enclosure without success. Always same outcome. The drive appears (with serial number) in Computer Management/System Tools/Device Manager/Disk Drives but does not appear in Computer Management/Storage/Disk Management.

I have downloaded and am running TestDisk. It has recognised my external USB hard drive with correct size which looks promising. However, when I get to window "Should TestDisk search for...Vista...." the keyboard does not work so I can not write the required Y or N (up until this screen keyboard works fine). I have rebooted and retried several times using different keyboards (both USB and non USB). Any suggestions?

The screen has now changed on the machine that I am running testdisk on. Currently showing:

Analyse cylinder 122 / 30399 : 00%

Read error at 121 / 1 / 1

After watching it for a while I noticed that every Analyse cylinder number produces a corresponding read error on the next line.

Shall I just leave it running for a few days?

Might be advisable to avoid stressing HDD.
Some manufacturer of external disks using hardware encryption.

Please check it.

No, currently it's not advisable to stress your disk as much.
Otherwise it's depend on how many read errors you receive?
If there only a few, you can consider to create an image or clone to another intact disk.
