I recently bought 2 different USB flash disks. These are some cheap no-name devices. Their parameters:
bytes C/H/S ID 4194304512 509/255/63 Vendor: Generic Model: USB Flash Drive Rev: 1.00 ANSI SCSI revision: 02 4288676352 1023/132/62 Vendor: USB Model: USB 2.0 Rev: 1.00 ANSI SCSI revision: 02 When I put a FAT32 filesystem on them, everything is OK, but when I put an ext3 filesystem, everything is OK when I write files to the disk, I can fill it with files, but then when I remove the disk from the computer (after a proper umount) and putting it in again, most of the files have corrupted direcotry entries (they look red in midnight commander, some of them pink). But some (about 5 to 10%) files are normal, and normally accessible. I tried them both on two completely different computers with very different hardware, and different Linux versions, and the effect is the same. One of the computers is a desktop with and old AMD K7 Clayton motherboard with only old USB1.1: VT82xxxxx UHCI USB 1.1 Controller, and Debian sid with 2.6.18-4-k7 kernel from Debian. The other computer is a much newer AMD Athlon64 HP laptop with USB2.0 port and SuSE 10.2. Did anyone observe anything similar with any USB flash drives (FAT OK, ext3 corrupted)? -- Miernik http://miernik.name/ ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
