Re: Any linux-based microSD utilities?
Max Pyziur wrote: Greetings, I have a Kingston 4GB microSD card in my cellphone. I use a microSD USB reader to move files to and from the card (pdfs, mp3s, etc). I tend to move it between phones and computers a fair amount. It seems that the card has failed and does not auto-mount properly on either my desktop or laptop, both of which run F12, or on my phone now. However, reviewing /var/log/messages I see that the relevant daemons sense the card and create a block device (/dev/sdb or /dev/sdc depending on the machine) when I use the USB reader and insert it into a USB port. However, the device doesn't automount, nor can I mount it from root. If the card has failed, I'd like to try and recover whatever data I can. Can the card be made useable again through some sort of formatting utility? Any guidance would be appreciated. Start by using fdisk -l /dev/XXX from command line, where XXX is the sd device. If you are lucky there will still be a partition /dev/XXX1/ which you can try to recover (and can dd it into a disk file for more future trials). -- Bill Davidsen david...@tmr.com We have more to fear from the bungling of the incompetent than from the machinations of the wicked. - from Slashdot -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines

You could have a card failure or a corrupt filesystem (or both). Try reading the card with something like: dd if=/dev/sdb of=myflakeycard.dd bs=2M conv=sync,noerror If that succeeds, the disk is probably OK. Usually they're vfat filesystems, so look into how to recover those. Can the card be made useable again through some sort of formatting utility? something like: mkfs -t vfat -n yourphonenumberhere /dev/sdb1 works in my phones and cameras. That'll wipe your data of course. The -n flag is optional, but in theory a number there will help an honest man return your lost device. It worked once for me anyway. -Bill -- Bill McGonigle, Owner BFC Computing, LLC http://bfccomputing.com/ Telephone: +1.603.448.4440 Email, IM, VOIP: b...@bfccomputing.com VCard: http://bfccomputing.com/vcard/bill.vcf Social networks: bill_mcgonigle/bill.mcgonigle -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines

2010/1/7 Max Pyziur p...@brama.com: If the card has failed, I'd like to try and recover whatever data I can. What you want is photorec, part of the testdisk program. It can search your devices on the block level and recover data. Afterwards, you can re-format it with VFAT as it's most likely a file allocation table corruption. -c -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
